[0001] This application claims the benefit of and priority to U.S. Provisional Patent Application No. 63 / 722,306, filed November 19, 2024, and U.S. Provisional Patent Application No. 63 / 740,395, filed December 31, 2024, both of which are incorporated by reference herein in their entireties.INTRODUCTION

[0002] Medical patients, such as patients who are mechanically ventilated, can require a tube (e.g., an endotracheal tube) inserted into their trachea. The tube can obstruct access to a patient’s mouth and prevent adequate administration of oral care to the patient.SUMMARY

[0003] The present disclosure relates to various oral medical devices that can provide irrigation fluid to the oral cavity to clean (e.g., rinse, wash, cleanse, flush out, or otherwise clean) the oral cavity of a patient. The oral irrigation devices can include a first portion to provide irrigation fluid to the oral cavity and a second portion to remove the irrigation fluid from the oral cavity. The first portion can be an irrigation portion. The irrigation portion can include at least one opening to provide irrigation fluid from a cavity of the irrigation portion to the oral cavity of the patient. The irrigation portion can be coupled with an irrigation conduit that is further coupled with an irrigation fluid source. Irrigation fluid can be provided to the irrigation portion via the irrigation conduit. The second portion can be a suction portion. The suction portion can include at least one suction opening through which irrigation fluid can pass from the oral cavity of the patient into a cavity of the suction portion. The suction portion can be coupled with a suction conduit that is further coupled to a suction device (e.g., a vacuum pump or other device configured to cause the cavity of the suction portion to be under negative pressure). The suction opening of the suction portion can be configured to allow irrigation fluid and other debris (e.g., particulate matter, mucus, or other secretions) to pass from the oral cavity of the patient to the cavity of the suction portion when the cavity of the suction portion is under negative pressure (e.g., negative pressure as applied by the suction device via the suction conduit). The suction portion can be configured to substantially prevent occlusion of the suction opening. For example, the suction portion can include the suction opening having a14931 -5214-5527.2Atty. Dkt: 139168-0149; SWF-008PCT geometry or other feature that can substantially prevent a tongue of the patient or large debris (e.g., particulate matter, mucus, or other secretions) from occluding the suction opening. The suction portion can include multiple suction openings, where the occlusion of some subset of the suction openings is unlikely to materially affect the efficacy or operation of the suction portion in removing debris and irrigation fluid from the oral cavity of the patient. For example, the suction portion can include a first suction opening and a second suction opening, where the second suction opening is configured to open when the first suction opening is occluded, such as when the cavity of the suction portion is under sufficiently high negative pressure by virtue of occlusion of the first suction opening. In other examples, the suction portion can include at least one movable or actuatable element that, in response to a user input or in response to an occlusion of a suction opening, is moved or actuated to remove the source of the occlusion or create a second suction opening to continue a suction operation despite an occlusion.

[0105] Following below are more detailed descriptions of various concepts related to, and implementations of, methods, apparatuses, and systems of oral irrigation. The various concepts204931 -5214-5527.2Atty. Dkt: 139168-0149; SWF-008PCT introduced above and discussed in greater detail below may be implemented in any of numerous ways.

[0106] Ventilated patients require a tube to be inserted into the trachea so that a ventilator can deliver oxygen to the lungs. The tube is generally an endotracheal tube, oral tube introduced via a tracheostomy. An end of the tube is coupled to tubing attached to a ventilator so that air can be delivered to and from the lungs and the distal end of the tube is disposed below the glottis into the trachea. Ventilated patients or other patients can experience undesirable accumulation of pathogens, microbes, bacteria, particulate matter, or other unwanted substances within their oral cavity. Specifically, the presence of an endotracheal tube or other tube within the patient’s oral cavity, particularly for long durations, can undesirably act as a reservoir for pathogens which may prevent or dramatically slow the formation of biofilms that contain pathogenic microorganisms. Beyond patients with an endotracheal tube or other tube within their oral cavity, cleaning and maintaining the cleanliness of the patients’ oral cavity can be challenging when the patient is in a hospital or other environment for any number of reasons (e.g., if the patient is unable to administer their own oral care or other complicating factors), which can also allow for the undesirable accumulation of pathogens, microbes, bacteria, particulate matter, or other unwanted substances. The present disclosure is directed to systems and methods of oral irrigation. Specifically, the present disclosure relates to medical devices that provide for irrigation of a medical patient’s oral cavity (e.g., the interior of a patient’s mouth, including the patient’s teeth, cheeks, gums, tongue, and other areas, among others).

[0107] The present disclosure relates to oral medical devices that can suction (e.g., remove, evacuate) irrigation fluid from the oral cavity of the patient, as may be necessary after a fluid is provided to the oral cavity of the patient to clean (e.g., rinse, wash, cleanse, flush out, or otherwise clean) the oral cavity. For example, the oral medical devices of the present disclosure can provide irrigation fluid to the oral cavity to clean the oral cavity and reduce an incidence of undesirable bacteria or pathogen growth within the oral cavity and simultaneously or subsequently suction the irrigation fluid and any other matter (e.g., mucous, debris, secretions, or other matter) to remove said irrigation fluid and other matter from the patient’s oral cavity. By effectively suctioning the oral cavity of the patient after an irrigation operation, for example, the patient’s oral cavity can be substantially free from pathogens, microbes, bacteria, particulate matter, or other unwanted substances. The present disclosure relates to214931 -5214-5527.2Atty. Dkt: 139168-0149; SWF-008PCT oral medical devices having an irrigation portion and a suction portion. The irrigation portion is configured to provide irrigation fluid to the patient’s oral cavity. The suction portion is configured to remove the irrigation fluid and any other matter from the patient’s oral cavity. The suction portion includes one or more suction apertures through which irrigation fluid or other matter enters the suction portion of the medical device from the patient’s oral cavity for removal from the oral cavity. The suction apertures can include at least one non-occlusion feature that is configured to prevent or substantially reduce the incidence of matter (e.g., thick mucus, secretions, or debris) from occluding (e.g., blocking, impeding, covering) the suction aperture of the suction portion. If the suction aperture is occluded — whether in part or in full — the efficacy of the suction aperture can be reduced undesirably, which can cause the suction portion to ineffectively remove irrigation fluid or other matter from the oral cavity of the patient. If the irrigation fluid and other matter is not effectively removed from the patient’s oral cavity, the undesirable pathogens, microbes, bacteria, particulate matter, or other unwanted substances can persist in the patient’s oral cavity, which can further lead to sub-optimal medical care or results.

[0108] The disclosed solutions have a technical advantage of providing improved oral care compared to conventional devices and techniques, such as conventional toothbrushes, mouth washing or rising techniques, or otherwise. By improving the cleanliness of the patient’s oral cavity, the various devices described herein can reduce a length for which a patient may need to remain mechanical ventilated or otherwise hospitalized by effectively removing bacteria and organic debris from the oral cavity, which can otherwise damage or impair a patient’s respiratory system and correspondingly slow the patient’s recovery. To provide improved oral care for ventilated patients, for example, the disclosed solutions provide for the irrigation of the patient’s oral cavity by both providing an irrigation fluid (e.g., water, saline solution, or some other fluid) to the oral cavity and suctioning (e.g., removing, evacuating, vacuuming) the provided irrigation fluid from the oral cavity. For example, after the irrigation fluid is introduced to the oral cavity, it can rinse the oral cavity and wash away bacteria, particulate matter, or any other undesirable substances within the oral cavity. The oral irrigation devices disclosed herein can then remove the provided irrigation fluid — which also contains the undesirable substances like bacteria and particulate matter — from the patient’s oral cavity. The disclosed solutions can both provide irrigation fluid and then remove the irrigation fluid without any external suction catheters or other separate suction devices. This benefit can further decrease risk of mucus membrane injury and may promote healthy mucous membranes.224931 -5214-5527.2Atty. Dkt: 139168-0149; SWF-008PCTThe oral irrigation devices disclosed herein can also allow for irrigation without unnecessary dwell time. For example, the irrigation fluid can be provided to the oral cavity of the patient and simultaneously removed from the oral cavity such that the irrigation fluid (which upon introduction to the oral cavity can contain bacteria, particulate matter, or other undesirable substances) does not remain within the oral cavity for any extended period of time. In addition, in light of the aforementioned manufacturing and performance advantages, among other benefits, the disclosed oral irrigation devices can provide a cost effective, efficient, and easy to use solution for irrigating a patient’s oral cavity. This can allow for frequent intervention to further expedite a patient’s recovery or avoid unnecessarily avoid protracting the same.

[0109] FIG. 1, among others, depicts an oral medical device 100. The oral medical device 100 can facilitate the irrigation and suctioning of an oral cavity of a patient. For example, the oral medical device 100 can be inserted into an oral cavity (e.g., a mouth) of a patient and can be configured to provide an irrigation fluid (e.g., water, saline solution, or some other irrigation fluid) into the oral cavity of the patient to irrigate the oral cavity of the patient. Irrigation can include providing fluid to the oral cavity to clean (e.g., cleanse, disinfect, wash, rinse, or otherwise clean) or provide some other therapeutic treatment to the oral cavity. For example, the oral medical device 100 can provide the irrigation fluid to the oral cavity, where the irrigation fluid can wash away pathogens, bacteria, particulate matter, or other undesirable substances that may have accumulated within the oral cavity of the patient. The oral medical device 100 can be inserted into the oral cavity of the patient and can be configured to suction (e.g., remove, evacuate via negative pressure, or otherwise draw out) the irrigation fluid (e.g., the irrigation fluid that is first provided into the oral cavity by the oral medical device 100), pathogens, bacteria, particulate matter, mucus, secretions, debris, or other material from the oral cavity of the patient. For example, the oral medical device 100 can remove the irrigation fluid from the oral cavity after the irrigation fluid has first been provided to the oral cavity to clean the oral cavity as well as mucus, secretions, and other debris that may be present within the oral cavity of the patient.

[0110] The oral medical device 100 can be used in conjunction with (e.g., simultaneously with) other medical devices, such as an endotracheal tube or some other medical device, as noted above. The oral medical device 100 can be used independent of any other medical device, in other examples. As mentioned above, the patient’s oral cavity can be in need of irrigation or cleaning (e.g., cleansing with solution, disinfection, scrubbing, removal of234931 -5214-5527.2Atty. Dkt: 139168-0149; SWF-008PCT microbes, bacteria or particulate matter, or some other type of cleaning) as the patient remains intubated (e.g., via an endotracheal tube). Moreover, the presence of an endotracheal tube or another medical device within the oral cavity of the patient can inhibit or obstruct access to the oral cavity and substantially prevent the irrigation or cleaning of the oral cavity by conventional means (e.g., brushing with tooth brush, rinsing with water, or some other means.) Further, if the patient is ventilated, it can be undesirable to irrigate or clean the oral cavity of the patient by conventional means because to do so may risk introducing fluid into the patient’s lungs.

[0111] The oral medical device 100 can include a first portion 105 and a second portion 110. The first portion 105 can be an irrigation portion 105. The second portion 110 can be a suction portion 110. For example, the oral medical device 100 can provide irrigation fluid into the oral cavity of a patient via the first portion 105 and can remove fluid from the oral cavity of the patient. The oral medical device 100 can be positioned within an oral cavity of a patient with the first portion 105 positioned to one side of the patient’s oral cavity and the second portion 110 positioned to an opposite side of the patient’s oral cavity. For example, the first portion 105 can be positioned proximate an inner tissue surface of a first cheek (e.g., a right cheek or a left cheek) and the second portion can be positioned proximate an inner tissue surface of a second cheek (e.g., a left cheek or a right cheek). In such examples, a tongue of the patient can be positioned between the first portion 105 and the second portion 110. For example, the first portion 105 and the second portion 110 can be positioned to the sides (e.g., left and right sides) of a patient’s oral cavity substantially without occupying a space within the patient’s oral cavity inward relative to an inner surface of the patient’s teeth, as such space may be occupied by the patient’s tongue, an endotracheal tube, or otherwise.

[0112] The first portion 105 can include at least one first paddle 115 (e.g., an end portion, a tip, or some other portion), a stem 140, and a junction 145. The first paddle 115 can be configured to facilitate the providing (e.g., dispensing, emitting, injecting, spraying) of irrigation fluid into the oral cavity of the patient to further facilitate the irrigation fluid of the oral cavity. The junction 145 of the first portion 105 can be a region (e.g., area, zone, portion) of the first portion 105 between the stem 140 and the first paddle 115. For example, the stem 140 can transition into the first paddle 115 at or proximate to (e.g., within two centimeters of) the junction 145. The first portion 105 can include at least one grip tab or other portion to facilitate a user’s gripping or grasping of the oral medical device 100.244931 -5214-5527.2Atty. Dkt: 139168-0149; SWF-008PCT

[0113] The first portion 105 can include a first member 200 or half (e.g., an upper or lower member) and a second member 205 or half (e.g., a lower or upper member). For example, the first portion 105 can be constructed by coupling the first, upper member 200 with the second, lower member 205. The first member 200 can a portion or entirety of the stem 140. The second member 205 of the first portion 105 can include a portion or entirety of the stem 140. The first portion 105 can include a first cavity 225 (e.g., an irrigation cavity). For example, first member 200 and the second member 205 of the first portion can be coupled together to form the irrigation cavity 225 positioned between the first member 200 and the second member 205 of the first portion 105. For example, the first member 200 and the second member 205 of the first portion 105 can respectively include an inner surface, and the irrigation cavity 225 can be disposed between the inner surfaces of the first member 200 and the second member 205 of the first portion 105. The inner surface of the first member 200 and the second member 205 of the first portion 105 can respectively be recessed relative to a perimeter (e.g., outer edge) of the first member 200 and the second member 205. Accordingly, the first cavity 225 of the first portion 105 can be the spaced between the inner surface of the first member 200 and the inner surface of the second member 205 of the first portion 105. The first cavity 225 can be fluidly coupled with the stem 140 such that fluid passing through the stem 140 can flow into the first cavity 225 and vice versa.

[0114] The first paddle 115 of the first portion 105 can include at least one first opening 150. The first opening 150 can be an opening (e.g., a hole, an aperture, a void, a passageway, a lumen, an outlet, or some other opening) that can facilitate a flow of fluid from the first cavity 225 and out of the first paddle 115. The first opening 150 can be formed in the first member 200 or the second member 205 of the first portion 105. For example, the first opening 150 can be extend through the first member 200 and to the first cavity 225. The first opening 150 can be extend through the second member 205 and to the first cavity 225. The first opening 150 can be positioned at any location along the first paddle 115, or otherwise. For example, the first opening 150 can be positioned on a central portion of the first paddle 115. The first opening 150 can be positioned on an edge or periphery of the first paddle 115. For example, the first opening 150 can be positioned on an edge or periphery of the first paddle 115 at a juncture or seam between the first member and second member of the first portion 105 such that the first opening 150 resembles a notch, groove, or indentation, for example. The first paddle 115 can include multiple first openings 150. For example, the first paddle 115 can include multiple first openings 150 extending through the first member 200 and multiple first254931 -5214-5527.2Atty. Dkt: 139168-0149; SWF-008PCT openings 150 extending through the second member 205. In such an arrangement fluid (e.g., an irrigation fluid) can flow from the irrigation cavity and into the oral cavity of a patient via the multiple first openings 150. The multiple first openings 150 can be variously positioned on the first paddle 115 to strategically direct fluid within the oral cavity. For example, the various first openings 150 can be positioned so as to cover as great an area within the oral cavity with an irrigation fluid as possible. To accomplish such substantial coverage with fluid, the first openings 150 can dispense irrigation fluid in multiple different directions (e.g., at varying exit angle relative to the first paddle 115).

[0115] The first portion 105 can include a rigid or semi-rigid polymeric material. For example, the first member 200 and the second member 205 of the first portion 105 can be injection molded components that are made of a rigid or high durometer material, such as polypropylene, polyester, copolyester, polycarbonate, styrene acrylic copolymers, styrene block copolymer (SBC), ABS, high durometer TPU, polyethylene, or some other material. Because the first member 200 and the second member 205 can be injection molded, the first opening 150 formed therein can include an orientation or geometry to facilitate ease of manufacturing. For example, the first openings 150 can include a geometry or orientation that allows for injection molding using single-pull or single-pull injection mold tooling, which can be cheap to manufacture and maintain as compared to more complicated tooling. Further, the quality of the molded first member 200 and the second member 205 can be improved by virtue of using simpler tooling that is inherently more error-proof. The first portion 105 can include a resilient material, such as a silicone, rubber, latex, or other material. For example, a region or portion of the first portion 105 can include a resilient material that allows a size or shape of the first opening 150 to vary as the resilient material flexes, expands, or is otherwise manipulated.

[0116] The first member 200 can couple with the second member 205. For example, the first member 200 and the second member 205 can be coupled together to form the first portion 105 of the oral medical device 100. The first member 200 and the second member 205 define a seam. The seam can be an interface between an inner-most portion (e.g., edge, face, side, perimeter, or other portion) of the first member 200 and the inner-most portion (e.g., edge, face, side, perimeter, or other portion) of the second member 205. The first member 200 can be coupled with the second member 205 to create at least a partial seal between the first member 200 and the second member 205 such that fluid provided into the first cavity 225 flows from the first paddle 115 via the first opening 150, rather than at the interface between the first264931 -5214-5527.2Atty. Dkt: 139168-0149; SWF-008PCT member 200 and the second member 205 (e.g., at the seam). For example, a sufficiently strong seal between the first member 200 and the second member 205 is desirable to cause all or a substantial majority of an irrigation fluid to flow through the first opening 150 as intended.

[0117] The oral medical device 100 can include the first portion 105 fluidly coupled with at least one first conduit 125. For example, the first conduit 125 can be coupled with the stem 140 of the first portion 105. The first conduit 125 can be configured to facilitate the flow of a fluid to or from the first portion 105. For example, the first conduit 125 can be an irrigation portion 105 that can be configured to provide an irrigation fluid to the first cavity 225 of the first paddle 115 via the stem 140 of the first portion 105. The first conduit 125 can include a flow passage 135 (e.g., a lumen, a passageway, an internal channel, or some other passage) to allow the first conduit 125 to conduct (e.g., move, channel, flow, draw, provide) fluid to the first portion 105. For example, the first conduit 125 can be fluidly coupled with the stem 140 such that the first conduit 125 is also fluidly coupled with the first cavity 225 of the first paddle 115 of the first portion 105. The first conduit 125 can provide irrigation fluid to the first cavity 225 of the first paddle 115 where the irrigation fluid can be further dispensed from the first opening 150 and into the oral cavity of the patient. For example, the first conduit 125 can be fluidly coupled with a pump device (e.g., a motorized pump, a manual pump, a syringe, or some other pump device) that is configured to provide (e.g., force, push, pump) the irrigation fluid through the flow passage 135 of the first conduit 125 and into the first cavity 225 of the first paddle 115. The pump can provide fluid to the first cavity 225 of the first paddle 115 via the first conduit 125 with the fluid under pressure or force. With the fluid under pressure or force, the fluid can flow out of the first opening 150 of the first paddle 115 and into the oral cavity of the patient, which can be a comparatively low pressure environment. For example, the first opening 150 can be fluidly coupled with the oral cavity of the patient and can represent an open flow path for the irrigation fluid to flow. A pressure differential between the first cavity 225 and the oral cavity of the patient can cause the irrigation fluid within the first cavity 225 to flow via the first opening 150 and into the oral cavity of the patient, for example. In this way, the first portion 105 can act as an irrigation device to provide irrigation fluid to the oral cavity of the patient via the first opening 150 of the first paddle 115 via the second conduit 130.

[0118] The second portion 110 (e.g., the suction portion 110) can include at least one second paddle 120 (e.g., an end portion, a tip, or some other portion), a stem 140, and a junction 145. The second paddle 120 can be configured to facilitate the suctioning of irrigation274931 -5214-5527.2Atty. Dkt: 139168-0149; SWF-008PCT fluid from the oral cavity of the patient and to further facilitate the providing of suctioned irrigation fluid to the stem 140 of the second portion 110 and ultimately to a second conduit 130. The junction 145 of the second portion 110 can be a region (e.g., area, zone, portion) of the second portion 110 between the stem 140 and the second paddle 120. For example, the stem 140 can transition into the second paddle 120 at or proximate to (e.g., within two centimeters of) the junction 145.

[0119] As depicted in FIG. 2, among others, the second portion 110 can include a first member 210 or half (e.g., an upper or lower member) and a second member 215 or half (e.g., a lower or upper member). For example, the second portion 110 can be constructed by coupling an upper member 210 with a lower member 215. Although the first member 210 is shown as being an upper-most member of the second portion 110 and the second member 215 is shown as being a lower-most member of the second portion 110, it is understood that the oral medical device does not require the precise orientation of the oral medical device 100 as shown in FIG. 2, among others. Indeed, it is understood that the orientation of the oral medical device 100 can vary (e.g., during use or otherwise) such that the first member 210 can be positioned vertically above the second member 215, or in some other orientation in space. The first member 210 can be coupled with the second member 215 to form the second portion 110. As depicted in FIG. 2, the second member 215 includes the stem 140, while the first member 210 does not. In other examples, the first member 210 can include the stem 140. In other examples, the second member 215 can include the stem 140. In yet other examples, such as those shown in FIGS. 10 and 11, among others, the first member 210 and the second member 215 can both include a portion of the stem 140 such that, when the first member 210 and the second member 215 are coupled, they collectively define the stem 140.

[0120] The second portion 110 can include a cavity 230, such as a second cavity 230 or a suction cavity 230. For example, first member 210 and the second member 215 can be coupled together to form the second cavity 230 positioned between the first member 210 and the second member 215 of the second portion 110. For example, the second member 215 of the second portion 110 can include an inner surface and the first member 210 of the second portion 110 can include an inner surface, where the inner surfaces of the first member 210 and the second member 215 cooperate to define the second cavity 230. The second cavity 230 can be fluidly coupled with the stem 140 such that fluid passing through the second cavity 230 can flow into the stem 140 and vice versa.284931 -5214-5527.2Atty. Dkt: 139168-0149; SWF-008PCT

[0121] The second paddle 120 of the second portion 110 can include at least one opening, shown in FIGS. 1 and 2, among others, as a suction opening 155 or a second opening 155. The suction opening 155 can be an opening (e.g., a hole, an aperture, a void, a passageway, a lumen, or some other opening) that can facilitate a flow of fluid or other material (e.g., mucus, secretions, debris, or other material) from some external environment (e.g., an oral cavity of a patient) and to the second cavity 230 of the second paddle 120. The suction opening 155 can be formed in the first member 210 or the second member 215 of the second portion 110 in embodiments where the second portion 110 is constructed from the first member 210 and the second member 215. For example, the suction opening 155 can be extend through the first member 210 of the second portion 110 and to the second cavity 230. The suction opening 155 can be extend through the second member 215 of the second portion 110 and to the second cavity 230. The second paddle 120 can include multiple suction openings 155. For example, the second paddle 120 can include at least one suction opening 155 extending through a top side (e.g., through the first member 210 of the second portion 110) and at least one suction opening 155 extending through a lower side (e.g., through the second member 215 of the second portion 110). In such an arrangement, fluid or other material (e.g., mucus, secretions, debris, or other material) can flow from the oral cavity of the patient and into the second cavity 230 via the multiple suction openings 155. The multiple suction openings 155 can be variously positioned on the second paddle 120 to effectively and efficiently draw fluid and other material (e.g., mucus, secretions, debris, or other material) out of the oral cavity and into the second cavity 230. For example, the various suction openings 155 can be positioned so as to draw irrigation fluid or other material from a location of the oral cavity in which said fluid or other material has a propensity to pool, collect, or otherwise aggregate. In this way, the suction openings 155 of the second paddle 120 can remove a substantial amount of fluid or other material from the oral cavity so as to facilitate effective irrigation of the oral cavity and to prevent fluid from undesirably remaining within the oral cavity of the patient. The suction opening 155 can be positioned at any location along the first member 210 of the second portion, the second member 215 of the second portion, or otherwise. For example, the suction opening 155 can be positioned on a central portion of the first member 210 or the second member 215 of the second portion 110. The suction opening 155 can be positioned on edge or periphery of the first member 210 or the second member 215 of the second portion 110 such that the second opening 155 resembles a notch, groove, or indentation, for example.

[0122] The second portion 110 can include a rigid or semi-rigid polymeric material. For294931 -5214-5527.2Atty. Dkt: 139168-0149; SWF-008PCT example, the first member 210 and the second member 215 of the second portion 110 can be injection molded components that are made of a rigid or high durometer material, such as polypropylene, polyester, copolyester, polycarbonate, styrene acrylic copolymers, styrene block copolymer (SBC), ABS, high durometer TPU, polyethylene, or some other material. Because the first member 210 and the second member 215 of the second portion 110 can be injection molded, the suction opening 155 formed therein can include an orientation or geometry to facilitate ease of manufacturing. For example, the suction openings 155 can include a geometry or orientation that allows for injection molding using single-pull or single-pull injection mold tooling, which can be cheap to manufacture and maintain as compared to more complicated tooling. Further, the quality of the molded first member 210 and the second member 215 can be improved by virtue of using simpler tooling that is inherently more errorproof. The second portion 110 can include a resilient material, such as a silicone, rubber, latex, or other material. For example, a region or portion of the second portion 110 can include a resilient material that allows a size or shape of the second portion 110 to vary as the resilient material flexes, expands, or is otherwise manipulated. The suction opening 155 of the second portion 110 can be or include a resilient or flexible material such that a size or shape of the suction opening 155 can vary as the resilient or flexible material flexes, expands, or otherwise moves. For example, the second portion 110 can include a suction opening 155 that is closed in certain circumstances (e.g., when a negative pressure within the second cavity 230 is below a certain threshold) and open in other circumstances (e.g., when the negative pressure within the second cavity 230 is above a certain threshold), where movement of the opening 155 from a closed position to an open position occurs at least partially by virtue of the flexure or movement of the resilient or flexible material that is possible at least partially by virtue of a material property of the resilient or flexible material.

[0123] The first member 210 can couple with the second member 215 of the second portion 110. For example, the first member 210 and the second member 215 of the second portion 110 can be coupled together to form the second portion 110 of the oral medical device 100. The first member 210 and the second member 215 can define a seam. The seam can be an interface between an inner-most portion (e.g., edge, face, side, perimeter, or other portion) of the first member 210 and the inner-most portion (e.g., edge, face, side, perimeter, or other portion) of the second member 215. The first member 210 can be coupled with the second member 215 to create at least a partial seal between the first member 210 and the second member 215 such that negative (e.g., suction, vacuum) pressure within the second cavity 230 can build and be304931 -5214-5527.2Atty. Dkt: 139168-0149; SWF-008PCT substantially maintained such that fluid can flow into the second paddle 120 via the suction opening 155, rather than at the interface between the first member 210 and the second member 215 (e.g., at the seam). For example, in embodiments where the second portion is constructed by coupling the first member 210 with the second member 215, a sufficiently strong seal between the first member 210 and the second member 215 is desirable to achieve a sufficient suction force at the suction opening 155 and to consequently bolster the performance (e.g., suction efficacy) of the second portion 110.

[0124] The oral medical device 100 can include the second portion 110 coupled with a second conduit 130. For example, the second conduit 130 can be coupled with the stem 140 of the second portion 110. The second conduit 130 can be configured to facilitate the flow of fluid from or to the second portion 110. For example, the second portion 110 can be a suction portion 110 that can be configured to remove fluid or material (e.g., mucus, secretions, debris, or other material) from the oral cavity of the user and provide the removed fluid or material to the second conduit 130. The second conduit 130 can include a flow passage 135 (e.g., a lumen, a passageway, an internal channel, or some other passage) to allow the second conduit 130 to conduct (e.g., move, channel, flow, draw, provide) fluid to the second portion 110. For example, the second conduit 130 can be fluidly coupled with the stem 140 such that the second conduit 130 is also fluidly coupled with the second cavity 230 of the second paddle 120 of the second portion 110. The second conduit 130 can draw irrigation fluid within the oral cavity of the patient into the second cavity 230 of the second paddle 120 via the suction opening 155 of the second portion 110. For example, the second conduit 130 can be fluidly coupled with a vacuum pump, or some other device configured to suction (e.g., suck, draw, remove, vacuum, create negative pressure to remove) the irrigation fluid and any other matter from the oral cavity of the patient. By applying a suction force to the second conduit 130, the second cavity 230 of the second portion 110 can be under some amount of negative or vacuum pressure. The negative pressure within the second cavity 230 of the second portion 110 can cause the fluid (e.g., irrigation fluid) or other material (e.g., mucus, secretions, debris, or other material) within the oral cavity of the patient to be drawn into the second cavity 230 via the suction opening 155 of the second portion 110. In this way, the second portion 110 can act as a suction device to suction fluid and other material from the oral cavity of the patient via the suction opening 155, the second cavity 230, and the second conduit 130.

[0125] In other examples, the first portion 105 can be a suction portion configured to314931 -5214-5527.2Atty. Dkt: 139168-0149; SWF-008PCT remove and the second portion 110 can be an irrigation portion. For example, the first conduit 125 coupled with the first portion 105 can instead be coupled with a vacuum pump or similar device to subject the first cavity 225 of the first paddle 115 to negative pressure and correspondingly cause fluid (e.g., irrigation fluid within the oral cavity of the patient) to be drawn into the first cavity 225 of the first paddle 115 via the first opening 150. The second conduit 130 can be coupled with a pump or similar device to provide fluid (e.g., irrigation fluid) to the second cavity 230 and correspondingly cause the fluid to be dispensed from the second cavity 230 of the second paddle 120 via the second opening 155.

[0126] Referring now to FIGS. 3 and 4, among others, the second portion 110 of the oral medical device 100 is shown with a suction element 300 (e.g., a suction portion, a suction paddle). The suction element 300 includes at least one suction opening 305 (e.g., an aperture 305, a second opening 305) fluidly coupled with the cavity 230 of the second portion 110. The cavity 230 can be positioned within the suction element 300. The suction opening 305 can be an opening through which irrigation fluid or other material (e.g., mucus, secretions, debris, or other material) can be drawn into the cavity 230 within the suction element 300. For example, the suction element 300 can be coupled with the second conduit 130, which can further be under vacuum pressure or negative pressure to draw the irrigation fluid and other material form the oral cavity of the patient and into the suction cavity 230 of the suction element 300 to remove said irrigation fluid and other material from the oral cavity of the patient. The suction opening 305 can be disposed on a distal end of the suction element 300, where the distal end of the suction element 300 can be an end or tip of the suction element 300 that is positioned farthest within a patient’s oral cavity during operation of the oral medical device 100. The second conduit 130 can be coupled with a proximal end of the suction element 300, for example. In other examples, the suction element 300 can include the suction opening 305 positioned elsewhere, such as on an inner surface 310 of the suction element 300, on an outer surface of the suction element 300, or some other surface of the suction element 300. In yet other embodiments, the suction element 300 can include multiple suction openings 305 positioned in various positions on the suction element 300.

[0127] The suction element 300 includes a projection 315. The projection 315 can extend from the inner surface 310 of the suction element 300. For example, the projection 315 can extend from the inner surface 310 of the suction element 300 toward the first portion 105 of the oral medical device 100, which can be positioned to an opposite side of a patient’s oral cavity324931 -5214-5527.2Atty. Dkt: 139168-0149; SWF-008PCT during operation of the oral medical device 100 with the patient’s tongue disposed therebetween. The projection 315 can be positioned on the suction element 300 between the distal end of the suction element 300 (e.g., an end on which the suction opening 305 is disposed) and the proximal end of the suction element 300 (e.g., an end to which the second conduit 130 is coupled). The projection 315 can include a T-shaped profile or some other form factor having a central portion 325 extending from the inner surface 310 of the suction element 300 and at least one extension portion 320 that further extends from the central portion 325. In some embodiments, the extension portion 320 can extend in a direction that differs from a direction in which the central portion 325 extends from the inner surface 310. For example, the central portion 325 of the projection 315 can extend substantially perpendicular (e.g., ± 30° from perpendicular) relative to the inner surface 310 of the suction element 300, while the extension portion 320 can extends substantially perpendicular (e.g., ± 30° from perpendicular) relative to the central portion 325. In such embodiments, a groove (e.g., slot, opening, valley, crevice, recess) can exist between the inner surface 310 and the extension portion 320.

[0128] The projection 315 can contact a tongue of a patient during operation of the oral medical device 100. For example, the projection 315 can contact the tongue of the patient to keep the tongue of the patient substantially away from the suction opening 305 of the suction element 300. By keeping the tongue of the patient away from the suction opening 305, the projection 315 can substantially prevent or reduce the incidence of the suction opening 305 becoming at least partially occluded by the tongue of the patient. For example, if the tongue of the patient partially occludes the suction opening 305, the efficacy of the suction opening 305 in removing irrigation fluid or other material from the oral cavity of the patient is reduced. Because the projection 315 extends from the inner surface 310 of the suction element 300 and at least partially toward the first portion 105 (e.g., toward the tongue of the patient), the projection 315 is positioned to contact the tongue of the patient before the tongue of the patient can occlude the suction opening 305. The projection 315 stands proud relative to the suction element 300 to create or enforce a space or distance between the tongue of the patient and the suction opening 305 of the suction element 300, thereby substantially preventing occlusion of the suction opening 305 by the tongue of the patient.

[0129] FIG. 5, among others, depicts the second portion 110 of the oral medical device 100 having a suction element 500 (e.g., a suction portion, a suction paddle). The suction element 500 includes at least one suction opening 505 (e.g., an aperture 505, a second opening 505)334931 -5214-5527.2Atty. Dkt: 139168-0149; SWF-008PCT fluidly coupled with the cavity 230 of the second portion 110. The cavity 230 can be positioned within the suction element 500. The suction opening 505 can be an opening through which irrigation fluid or other material (e.g., mucus, secretions, debris, or other material) can be drawn into the cavity 230 within the suction element 500. For example, the suction element 500 can be coupled with the second conduit 130, which can further be under vacuum pressure or negative pressure to draw the irrigation fluid and other material form the oral cavity of the patient and into the suction cavity 230 of the suction element 500 to remove said irrigation fluid and other material from the oral cavity of the patient. The suction opening 505 can be disposed on a distal end of the suction element 500, where the distal end of the suction element 500 can be an end or tip of the suction element 500 that is positioned farthest within a patient’s oral cavity during operation of the oral medical device 100. The second conduit 130 can be coupled with a proximal end of the suction element 500, for example. In other examples, the suction element 500 can include the suction opening 505 positioned elsewhere, such as on an inner surface 515 of the suction element 500, an outer surface of the suction element 500, or some other surface of the suction element 500. The suction element 500 can include at least one second suction opening 510. The second suction opening 510 can be an opening through which irrigation fluid or other material (e.g., mucus, secretions, debris, or other material) can be drawn into the cavity 230 within the suction element 500. The second suction opening 510 can be positioned on the inner surface 515 of the suction element 500 and spaced apart from the suction opening 505, as shown in FIG. 5. In other embodiments, the second suction opening 510 can be positioned elsewhere on the suction element 500.

[0130] The suction element 500 includes a projection 520. The projection 520 can extend from the inner surface 515 of the suction element 500. For example, the projection 520 can extend from the inner surface 515 of the suction element 500 toward the first portion 105 of the oral medical device 100, which can be positioned to an opposite side of a patient’s oral cavity during operation of the oral medical device 100 with the patient’s tongue disposed therebetween. For example, the projection 520 can extend substantially perpendicularly (e.g., ± 30° from perpendicular) from the inner surface 515 of the suction element 500. The projection 520 can be positioned on the suction element 500 between the distal end of the suction element 500 (e.g., an end on which the suction opening 505 is disposed) and the proximal end of the suction element 500 (e.g., an end to which the second conduit 130 is coupled). The projection 520 can include a rectangular or linear cross-section in a first plane (e.g., a vertical plane) and a flared or curved profile in second plane (e.g., a horizontal plane). For example, the projection344931 -5214-5527.2Atty. Dkt: 139168-0149; SWF-008PCT520 can include a first end 525 positioned proximate the distal end of the suction element 500 and a second end 530 positioned proximate the proximal end of the suction element 500. The first end 525 of the projection can extend a first length from the inner surface 515 of the suction element 500, while the second end 530 can extend a second length from the inner surface 515 of the suction element 500. According to an exemplary embodiment, the second end 530 of the projection 520 can be a tapered end that is substantially flush with the inner surface 515 of the suction element 500. The projection 520 can have a width that is less than a width of the suction element 500. For example, the projection 520 can be thin relative to a width of the suction element 500. The projection 520 can include an aperture formed therethrough. In other embodiments, the projection 520 can be without any opening formed therethrough.

[0131] The projection 520 can contact a tongue of a patient during operation of the oral medical device 100. For example, the projection 520 can contact the tongue of the patient to keep the tongue of the patient substantially away from the suction opening 505 of the suction element 500. By keeping the tongue of the patient away from the suction opening 505, the projection 520 can substantially prevent or reduce the incidence of the suction opening 505 becoming at least partially occluded by the tongue of the patient. For example, if the tongue of the patient partially occludes the suction opening 505 or some other suction opening, the efficacy of the suction element 500 in removing irrigation fluid or other material from the oral cavity of the patient is reduced. Because the projection 520 extends from the inner surface 515 of the suction element 500 and at least partially toward the first portion 105 (e.g., toward the tongue of the patient), the projection 520 is positioned to contact the tongue of the patient before the tongue of the patient can occlude the suction opening 505 or some other suction opening (e.g., the second suction opening 510). The projection 520 stands proud relative to the suction element 500 to create or enforce a space or distance between the tongue of the patient and the suction opening 505 of the suction element 500, thereby substantially preventing occlusion of the suction opening 505 or some other suction opening by the tongue of the patient. The suction element 500 can include the second suction opening 510 positioned adjacent the projection 520. For example, the second suction opening 510 can be defined in the inner surface 515 of the suction element 500 and positioned substantially immediately (e.g., within 5mm) vertically above or below the projection 520. Because the second suction opening 510 is positioned proximate the projection 520, a patient cannot easily occlude the second suction opening 510 with their tongue.354931 -5214-5527.2Atty. Dkt: 139168-0149; SWF-008PCT

[0132] FIG. 6, among others, depicts the second portion 110 of the oral medical device 100 having a suction element 600 (e.g., a suction portion, a suction paddle). The suction element 600 includes at least one suction opening 605 (e.g., an aperture 605, a second opening 605) fluidly coupled with the cavity 230 of the second portion 110. The cavity 230 can be positioned within the suction element 600. The suction opening 505 can be an opening through which irrigation fluid or other material (e.g., mucus, secretions, debris, or other material) can be drawn into the cavity 230 within the suction element 600. For example, the suction element 600 can be coupled with the second conduit 130, which can further be under vacuum pressure or negative pressure to draw the irrigation fluid and other material form the oral cavity of the patient and into the suction cavity 230 of the suction element 600 to remove said irrigation fluid and other material from the oral cavity of the patient. The suction opening 605 can be disposed on a distal end of the suction element 600, where the distal end of the suction element 600 can be an end or tip of the suction element 600 that is positioned farthest within a patient’s oral cavity during operation of the oral medical device 100. The second conduit 130 can be coupled with a proximal end of the suction element 600, for example. In other examples, the suction element 600 can include the suction opening 605 positioned elsewhere, such as on an inner surface 610 of the suction element 600, an outer surface of the suction element 600, or some other surface of the suction element 600.

[0133] The suction element 600 can include at least one expandable region 615. The expandable region 615 can selectively expand or project from the suction element 600. For example, the expandable region 615 can selectively expand or project from the inner surface 610 of the suction element 600 in a direction at least partially toward the first portion 105 of the oral medical device 100, which can be positioned to an opposite side of a patient’s oral cavity during operation of the oral medical device 100 with the patient’s tongue disposed therebetween. The expandable region 615 can be fluidly coupled to an inflator device 625 via a conduit 620. For example, expandable region 615 can be or include an inflatable member 615, such as an air bag or other selectively expandable container (e.g., pouch, bag, vessel, or other container). The inflator device 625 can be a pump that, when actuated, can pump fluid (e.g., air or some other gas or liquid) via the conduit 620 to the inflatable member 615 to inflate the inflatable member 615 or otherwise cause the expansion thereof. In other examples, the inflator device 625 can be a valve that, when opened, allows a fluid to flow via the conduit 620 to the inflatable member 615, where the fluid can cause the inflation or movement of the inflatable member 615. The inflator device 625 can be automatically actuated via some364931 -5214-5527.2Atty. Dkt: 139168-0149; SWF-008PCT controller or other device. The inflator device 625 can be actuated in response to a user input (e.g., an input received via a switch or some other user input). The inflator device 625 can be powered (e.g., an electric pump) or non-powered (e.g., a manual pump, such as a hand pump). To facilitate or enable the expansion or inflation of the inflatable member 615, the inflatable member 615 can include a flexible, expandable, or elastic material. For example, the inflatable member 615 can include an elastomeric or resilient material that can expand (e.g., in response to a fluid provided by the inflator device 625) from an initial position to an expanded position, and then return from the expanded position to the initial position (e.g., in response to a removal of the fluid).

[0134] The expandable region 615 can selectively contact a tongue of a patient to create a distance between the tongue and the second aperture. For example, the inflatable member 615 can expand relative to an inner surface 610 of the suction element 600 to selectively contact a tongue of the patient. The inflatable member 615 can expand relative to an inner surface 610 in response to a fluid being provided to the inflatable member 615 via the conduit 620. For example, the inflator device 625 can provide air or some other fluid via the conduit 620 to the inflatable member 615, where the fluid can cause the inflatable member 615 to expand relative to the inner surface 610 of the suction element 600. The inflatable member 615 can expand relative to the inner surface 610 such that, when in an inflated state, the inflatable member 615 stands proud relative to the inner surface 610. The inflatable member 615 can contact a tongue of a patient during operation of the oral medical device 100. For example, the inflatable member 615 can contact the tongue of the patient to keep the tongue of the patient substantially away from the suction opening 605 of the suction element 600 with the inflatable member 615 in an inflated state. By keeping the tongue of the patient away from the suction opening 605, the inflatable member 615 can substantially prevent or reduce the incidence of the suction opening 605 becoming at least partially occluded by the tongue of the patient. For example, if the tongue of the patient partially occludes the suction opening 605 or some other suction opening, the efficacy of the suction element 600 in removing irrigation fluid or other material from the oral cavity of the patient is reduced. Because the inflatable member 615 selectively extends from the inner surface 610 of the suction element 600 and at least partially toward the first portion 105 (e.g., toward the tongue of the patient), the inflatable member 615 can selectively contact the tongue of the patient to keep or move the tongue of the patient away from the suction opening 605 and thereby substantially prevent occlusion of the suction opening 605 or some other suction opening (e.g., a second suction opening 630). For example,374931 -5214-5527.2Atty. Dkt: 139168-0149; SWF-008PCT the inflatable member 615 stands proud relative to the suction element 600 to create or enforce a space or distance between the tongue of the patient and the suction opening 605 of the suction element 600, thereby substantially preventing occlusion of the suction opening 605 or some other suction opening by the tongue of the patient. In the event the tongue of the patient partially occludes the suction opening 605 during operation of the oral medical device 100, the inflator device 625 can be actuated to inflate the inflatable member 615, where inflation of the inflatable member 615 can move the tongue of the patient away from the suction opening 605. In this way, the suction element 600 can dynamically move the tongue of the patient away from the suction opening 605 to alleviate an occluded state of the suction opening 605.

[0135] The suction element 600 can include at least one second suction opening 630. The second suction opening 630 can be an opening through which irrigation fluid or other material (e.g., mucus, secretions, debris, or other material) can be drawn into the cavity 230 within the suction element 600. The suction element 600 can include the second suction opening 630 positioned adjacent the expandable region 615. For example, the expandable region 615 can have a looped portion, and second suction opening 630 can be defined in the inner surface 610 of the suction element 600 and positioned within the looped portion of the expandable region 615. Because the second suction opening 630 is positioned within the looped portion of the expandable region 615, a patient cannot easily occlude the second suction opening 630 with their tongue, for example.

[0136] FIG. 7, among others, depicts the second portion 110 of the oral medical device 100 having a suction element 700 (e.g., a suction portion, a suction paddle). The suction element 700 includes at least one suction opening 705 (e.g., an aperture 705, a second opening 705) fluidly coupled with the cavity 230 of the second portion 110. The cavity 230 can be positioned within the suction element 700. The suction opening 705 can be an opening through which irrigation fluid or other material (e.g., mucus, secretions, debris, or other material) can be drawn into the cavity 230 within the suction element 700. For example, the suction element 700 can be coupled with the second conduit 130, which can further be under vacuum pressure or negative pressure to draw the irrigation fluid and other material form the oral cavity of the patient and into the suction cavity 230 of the suction element 700 to remove said irrigation fluid and other material from the oral cavity of the patient. The suction opening 705 can be disposed on a distal end of the suction element 700, where the distal end of the suction element 700 can be an end or tip of the suction element 700 that is positioned farthest within a patient’s384931 -5214-5527.2Atty. Dkt: 139168-0149; SWF-008PCT oral cavity during operation of the oral medical device 100. The second conduit 130 can be coupled with a proximal end of the suction element 700, for example. In other examples, the suction element 700 can include the suction opening 705 positioned elsewhere, such as on an inner surface 710 of the suction element 700, an outer surface of the suction element 700, or some other surface of the suction element 700. The suction element 700 can include at least one second suction opening 715. The second suction opening 715 can be an opening through which irrigation fluid or other material (e.g., mucus, secretions, debris, or other material) can be drawn into the cavity 230 within the suction element 700. The second suction opening 715 can be positioned on the inner surface 710 of the suction element 700 and spaced apart from the suction opening 705, as shown in FIG. 7. In other embodiments, the second suction opening 715 can be positioned elsewhere on the suction element 700.

[0137] The suction element 700 includes a projection 720. The projection 720 can extend from the inner surface 710 of the suction element 700. For example, the projection 720 can extend from the inner surface 710 of the suction element 700 toward the first portion 105 of the oral medical device 100, which can be positioned to an opposite side of a patient’s oral cavity during operation of the oral medical device 100 with the patient’s tongue disposed therebetween. For example, the projection 720 can extend substantially perpendicularly (e.g., ± 30° from perpendicular) from the inner surface 710 of the suction element 700. The projection 720 can be positioned on the suction element 700 between the distal end of the suction element 700 (e.g., an end on which the suction opening 705 is disposed) and the proximal end of the suction element 700 (e.g., an end to which the second conduit 130 is coupled). The projection 720 can include a rectangular or linear cross-section in a first plane (e.g., a vertical plane) and a flared or curved profile in second plane (e.g., a horizontal plane). For example, the projection 720 can include a first end 725 positioned proximate the distal end of the suction element 700 and a second end 730 positioned proximate the proximal end of the suction element 700. The first end 725 of the projection 720 can extend a first length from the inner surface 710 of the suction element 700, while the second end 730 can extend a second length from the inner surface 710 of the suction element 700. According to an exemplary embodiment, the second end 730 of the projection 720 can be a tapered end that is substantially flush with the inner surface 710 of the suction element 700. The projection 720 can have a width that is less than a width of the suction element 700. For example, the projection 720 can be thinner than the suction element 700. The projection 720 can include an opening 735 formed therethrough.394931 -5214-5527.2Atty. Dkt: 139168-0149; SWF-008PCT

[0138] The projection 720 can contact a tongue of a patient during operation of the oral medical device 100. For example, the projection 720 can contact the tongue of the patient to keep the tongue of the patient substantially away from the suction opening 705 of the suction element 700. By keeping the tongue of the patient away from the suction opening 705, the projection 720 can substantially prevent or reduce the incidence of the suction opening 705 becoming at least partially occluded by the tongue of the patient. For example, if the tongue of the patient partially occludes the suction opening 705 or some other suction opening, the efficacy of the suction element 700 in removing irrigation fluid or other material from the oral cavity of the patient is reduced. Because the projection 720 extends from the inner surface 710 of the suction element 700 and at least partially toward the first portion 105 (e.g., toward the tongue of the patient), the projection 720 is positioned to contact the tongue of the patient before the tongue of the patient can occlude the suction opening 705 or some other suction opening (e.g., the second suction opening 715). The projection 720 stands proud relative to the suction element 700 to create or enforce a space or distance between the tongue of the patient and the suction opening 705 of the suction element 700, thereby substantially preventing occlusion of the suction opening 705 or some other suction opening by the tongue of the patient.

[0139] The suction element 700 can include the second suction opening 715 at least partially aligned with the projection 720. For example, the projection 720 can be at least partially aligned with the second aperture 715 and spaced apart from the second aperture 715. As depicted in FIG. 7, among others, the second opening 715 can be positioned within the opening 735 defied by the projection 720. In this way, the projection 720 can at least partially cover or be positioned over the second suction opening 715. For example, the opening 735 defined by the projection 720 can be positioned between the projection 720 and the surface 710 (e.g., an exterior surface) of the suction element 700. During operation of the oral medical device 100, irrigation fluid or other material (e.g., mucus, secretions, debris, or other material) can pass through the opening 735 and into the second suction opening 715. Because the second suction opening 510 is positioned underneath the projection 720, the second suction openings 715 are at least partially shielded by the projection 720. A patient cannot easily occlude the second suction opening 715 with their tongue with the second suction opening 715 positioned underneath the projection 720.

[0140] FIG. 8, among others, depicts the second portion 110 of the oral medical device 100404931 -5214-5527.2Atty. Dkt: 139168-0149; SWF-008PCT having a suction element 800 (e.g., a suction portion, a suction paddle). The suction element 800 includes at least one suction opening 805 (e.g., an aperture 805, a second opening 805) fluidly coupled with the cavity 230 of the second portion 110. The cavity 230 can be positioned within the suction element 800. The suction opening 805 can be an opening through which irrigation fluid or other material (e.g., mucus, secretions, debris, or other material) can be drawn into the cavity 230 within the suction element 800. For example, the suction element 800 can be coupled with the second conduit 130, which can further be under vacuum pressure or negative pressure to draw the irrigation fluid and other material form the oral cavity of the patient and into the suction cavity 230 of the suction element 800 to remove said irrigation fluid and other material from the oral cavity of the patient. The suction opening 805 can be disposed on a distal end of the suction element 800, where the distal end of the suction element 800 can be an end or tip of the suction element 800 that is positioned farthest within a patient’s oral cavity during operation of the oral medical device 100. The second conduit 130 can be coupled with a proximal end of the suction element 800, for example. In other examples, the suction element 800 can include the suction opening 805 positioned elsewhere, such as on an inner surface 810 of the suction element 800, an outer surface of the suction element 800, or some other surface of the suction element 800. The suction element 800 can include at least one second suction opening 815. The second suction opening 815 can be an opening through which irrigation fluid or other material (e.g., mucus, secretions, debris, or other material) can be drawn into the cavity 230 within the suction element 800. The second suction opening 815 can be positioned on the inner surface 810 of the suction element 800 and spaced apart from the suction opening 805, as shown in FIG. 8. In other embodiments, the second suction opening 815 can be positioned elsewhere on the suction element 800.

[0141] The suction opening 805 of the suction element 800 defines a flow path through which the irrigation fluid and other material (e.g., mucus, secretions, debris, or other material) flows to enter the cavity 230 of the second portion 110. The suction element 800 includes a plurality of projections 820 that at least partially surround the flow path of the suction opening 805. For example, the plurality of projection 820 can extend at least partially into the flow path of the suction opening 805. According to an exemplary embodiment, the suction opening 805 can be surrounded by two projections 820, each extending at least partially into the flow path of the suction opening 805. For example, the projections 820 can extend into the flow path of the suction opening 805 to narrow the flow path in at least one direction. The two projections 820 can approach each other within the flow path of the suction opening 805 to form a constricted414931 -5214-5527.2Atty. Dkt: 139168-0149; SWF-008PCT or narrowed region 825 of the suction opening 805.

[0142] The region 825 of the suction opening 805 can include a shape, profile, or dimension that differs from other regions of the suction opening 805. For example, the suction element 800 can include at least one projection 820 that extends into the flow path of the suction opening 805 to create the region 825 that is smaller than another region or regions of the flow path. As depicted in FIG. 8, among others, the suction element 800 can include two or more projections 820 extending into the flow path of the suction opening 805 from substantially opposing directions such that a top and bottom of the suction opening 805 has a first shape or profile (e.g., a rounded shape), while the region 825 of the flow path can include a different shape or profile (e.g., a linear or rectangular shape). The suction element 800 can include two or more projection 820 that extend into the flow path of the suction opening 805 a top and bottom of the suction opening 805 have a first dimension or cross-sectional area, while the region 825 of the flow path can include a smaller dimension or cross-sectional area. Collectively, the various regions of the suction opening 805 can form some irregular shape or profile (e.g., an hourglass shape or some other shape) having multiple regions.Advantageously, the irregular shape or profile of the suction opening 805 as formed by the projections 820 extending at least partially into the flow path can be difficult to occlude with a single object. For example, given the irregular shape or profile of the suction opening 805, a tongue of a patient or some other material (e.g., mucus, secretions, debris, or other material) is unlikely to simultaneously occlude every region of the suction opening 805, thereby minimizing the incidence of an efficacy-affecting occlusion of the suction opening 805.

[0143] FIGS. 9 and 10, among others, depict the second portion 110 of the oral medical device 100 having a suction element 900 (e.g., a suction portion, a suction paddle). The suction element 800 includes at least one suction opening 905 (e.g., an aperture 905, a second opening 905), a first side 910 (e.g., an inner side, a top side, a bottom side, or an outer side), and a second side 915 (e.g., an outer side, a bottom side, a top side, or an inner side). The suction opening 905 fluidly coupled with the cavity 230 of the second portion 110. The cavity 230 can be positioned within the suction element 900. The suction opening 905 can be an opening through which irrigation fluid or other material (e.g., mucus, secretions, debris, or other material) can be drawn into the cavity 230 within the suction element 900. For example, the suction element 900 can be coupled with the second conduit 130, which can further be under vacuum pressure or negative pressure to draw the irrigation fluid and other material form the424931 -5214-5527.2Atty. Dkt: 139168-0149; SWF-008PCT oral cavity of the patient and into the suction cavity 230 of the suction element 900 to remove said irrigation fluid and other material from the oral cavity of the patient. The suction opening 905 can be disposed proximate a distal end of the suction element 900, where the distal end of the suction element 900 can be an end or tip of the suction element 900 that is positioned farthest within a patient’s oral cavity during operation of the oral medical device 100. The second conduit 130 can be coupled with a proximal end of the suction element 900, for example. In other examples, the suction element 900 can include the suction opening 905 positioned on various sides of the suction element 900, such as on the first side 910 or the second side 915.

[0144] The suction element 900 can include an outer member 925 defining the first side 910 and the second side 915, where the cavity 230 is positioned within the outer member. The first side 910 of the suction element 900 can be positioned opposite the second side 915 of the suction element 900. For example, the first side 910 can be an inner side that faces a tongue of the patient, while the second side 915 can be an outer side that is positioned against or proximate to a cheek of the patient. The suction element 900 can include at least one recessed region. 920. For example, the outer member 925 can define the recessed region 920 having a curved profile. The suction opening 905 can be positioned within the recessed region 920. For example, the suction opening 905 can be positioned at or proximate to a base of the recessed region 920. In such a position, the suction opening 905 can be recessed or positioned inward relative to a remainder of the outer member 925. Because the suction opening is recessed relative to a remainder of the outer member 925, the suction opening 905 can be unreachable or in a position that is difficult to reach by a tongue of a patient, for example. Consequently, because the tongue of the patient cannot easily reach the suction opening 905, the suction opening 905 is not easily occluded by the tongue of the patient. In some embodiments, the suction element 900 can include two or more recessed regions 920, each corresponding to a suction opening 905. For example, the outer member 925 can define a first recessed region 920 and a second recessed region 920. A first suction opening 905 can be positioned within (e.g., at or proximate a base of) the first recessed region 920, and a second suction opening 905 can be positioned within (e.g., at or proximate a base of) the second recessed region 920. The first recessed region 920 can be positioned on the first side 910 of the suction element 900, while the second recessed region 920 can be positioned on the second side 915 of the suction element 900.434931 -5214-5527.2Atty.

[0145] FIG. 11, among others, depicts the second portion 110 of the oral medical device 100 is with a suction element 1100 (e.g., a suction portion, a suction paddle). The suction element 1100 includes at least one suction opening 1105 (e.g., an aperture 1105, a second opening 1105) fluidly coupled with the cavity 230 of the second portion 110. The cavity 230 can be positioned within the suction element 1100. The suction opening 1105 can be an opening through which irrigation fluid or other material (e.g., mucus, secretions, debris, or other material) can be drawn into the cavity 230 within the suction element 1100. For example, the suction element 1100 can be coupled with the second conduit 130, which can further be under vacuum pressure or negative pressure to draw the irrigation fluid and other material form the oral cavity of the patient and into the suction cavity 230 of the suction element 1100 to remove said irrigation fluid and other material from the oral cavity of the patient. The suction opening 1105 can be disposed proximate a distal end of the suction element 1100, where the distal end of the suction element 1100 can be an end or tip of the suction element 1100 that is positioned farthest within a patient’s oral cavity during operation of the oral medical device 100. The second conduit 130 can be coupled with a proximal end of the suction element 1100, for example. In other examples, the suction element 1100 can include the suction opening 1105 positioned elsewhere, such as on an inner surface 1110 of the suction element 1100, within a recessed region 1120 of the suction element 1100, on an outer surface of the suction element 1100, or some other surface of the suction element 1100. In yet other embodiments, the suction element 1100 can include multiple suction openings 1105 positioned in various positions on the suction element 1100.

[0146] The suction element 1100 includes a projection 1115. The projection 1115 can extend from the inner surface 1110 of the suction element 1100. For example, the projection 1115 can extend from the inner surface 1110 of the suction element 1100 toward the first portion 105 of the oral medical device 100, which can be positioned to an opposite side of a patient’s oral cavity during operation of the oral medical device 100 with the patient’s tongue disposed therebetween. The projection 1115 can be positioned on the suction element 1100 between the distal end of the suction element 1100 and the proximal end of the suction element 1100. The projection 1115 can extend from the inner surface 1110 of the suction element 1100 and define the recessed region 1120. For example, the projection 1115 can define a valley, crevice, trough, or other recessed region 1120. The recessed region 1120 can extend along the inner surface 1110 of the suction element 1100 between the inner surface 1110 and an interior face of the projection 1115. The suction opening 1105 can be positioned within the recessed444931 -5214-5527.2Atty. Dkt: 139168-0149; SWF-008PCT region 1120. For example, the suction opening 1105 can be positioned at or proximate to a base of the recessed region 1120. In such a position, the suction opening 1105 can be recessed or positioned inward relative to a remainder suction element 1100. Because the suction opening 1105 is recessed relative to a remainder of the suction element 1100, the suction opening 1105 can be unreachable or in a position that is difficult to reach by a tongue of a patient, for example. Consequently, because the tongue of the patient cannot easily reach the suction opening 1105, the suction opening 1105 is not easily occluded by the tongue of the patient.

[0147] The recessed region 1120 can define a flow path. For example, the recessed region can define a flow path along which irrigation fluid or other material (e.g., mucus, secretions, debris, or other material) can move as said irrigation fluid or other material approaches the suction opening 1105. The recessed region 1120 can include a flared geometry (e.g., shape or profile). For example, the recessed region 1120 can include a flared geometry having a wide portion and a narrow portion. The wide portion of the recessed region 1120 can be positioned proximate the distal end of the suction element 900. The narrow portion of the recessed region 1120 can be positioned between the proximal end and the wide portion of the recessed region 1120. The suction opening 1105 can be positioned within the recessed region 1120 at or proximate the base of the recessed region 1120 and proximate the wide portion of the recessed region 1120. In such examples, the flow path defined by the recessed region extends from the narrow portion of the recessed region 1120 to the wide portion of the recessed region 1120. The flow path defined by the recessed region can funnel or draw the irrigation fluid or other material (e.g., mucus, secretions, debris, or other material) toward the suction opening 1105.

[0148] The projection 1115 can contact a tongue of a patient during operation of the oral medical device 100. For example, the projection 1115 can contact the tongue of the patient to keep the tongue of the patient substantially away from the suction opening 1105 of the suction element 1100. By keeping the tongue of the patient away from the suction opening 1105, the projection 1115 can substantially prevent or reduce the incidence of the suction opening 1105 becoming at least partially occluded by the tongue of the patient. For example, if the tongue of the patient partially occludes the suction opening 1105, the efficacy of the suction opening 1105 in removing irrigation fluid or other material from the oral cavity of the patient is reduced. Because the projection 1105 extends from the inner surface 1110 of the suction element 1100 and at least partially toward the first portion 105 (e.g., toward the tongue of the454931 -5214-5527.2Atty. Dkt: 139168-0149; SWF-008PCT patient), the projection 1115 is positioned to contact the tongue of the patient before the tongue of the patient can occlude the suction opening 1105. The projection 1115 can stand proud relative to the inner surface 1110 of the suction element 1100 to create or enforce a space or distance between the tongue of the patient and the suction opening 1105 of the suction element 1100, thereby substantially preventing occlusion of the suction opening 1105 by the tongue of the patient.

[0149] FIG. 12, among others, depicts the second portion 110 of the oral medical device 100 is with a suction element 1200 (e.g., a suction portion, a suction paddle). The suction element 1200 includes at least one suction opening 1205 (e.g., an aperture 1205, a second opening 1205) fluidly coupled with the cavity 230 of the second portion 110. The cavity 230 can be positioned within the suction element 1200. The suction opening 1205 can be an opening through which irrigation fluid or other material (e.g., mucus, secretions, debris, or other material) can be drawn into the cavity 230 within the suction element 1200. For example, the suction element 1200 can be coupled with the second conduit 130, which can further be under vacuum pressure or negative pressure to draw the irrigation fluid and other material form the oral cavity of the patient and into the suction cavity 230 of the suction element 1200 to remove said irrigation fluid and other material from the oral cavity of the patient. The suction opening 1205 can be disposed proximate a distal end of the suction element 1200, where the distal end of the suction element 1200 can be an end or tip of the suction element 1200 that is positioned farthest within a patient’s oral cavity during operation of the oral medical device 100. The second conduit 130 can be coupled with a proximal end of the suction element 1200, for example. In other examples, the suction element 1200 can include the suction opening 1205 positioned elsewhere, such as on an inner surface 1210 of the suction element 1200, within a recessed region 1220 of the suction element 1200, on an outer surface of the suction element 1200, or some other surface of the suction element 1200. In yet other embodiments, the suction element 1200 can include multiple suction openings 1205 positioned in various positions on the suction paddle 1205.

[0150] The suction element 1200 can include at least one second suction opening 1215. The second suction opening 1215 can be an opening through which irrigation fluid or other material (e.g., mucus, secretions, debris, or other material) can be drawn into the cavity 230 within the suction element 1200. The second suction opening 1215 can be positioned on the inner surface 1210 of the suction element 1200 and spaced apart from the suction opening464931 -5214-5527.2Atty. Dkt: 139168-0149; SWF-008PCT1205. For example, the suction opening 1205 can be positioned at proximate to the distal end of the suction element 1200, while the second suction opening 1205 can be positioned within the recessed region 1220 of the suction element 1200. In other embodiments, the second suction opening 12125 can be positioned elsewhere on the suction element 1200.

[0151] The suction element 1200 can include at least one recessed region 1220. For example, the inner surface 1210 of the suction element 1200 can define multiple recessed regions 1220. The recessed regions 1220 can be positioned separated by a wall 1225. For example, a wall 1225 (e.g., a partition 1225) can be positioned between two adjacent recessed regions 1220. The wall 1225 can be a non-recessed portion of the inner surface 1210 that is positioned between adjacent recessed regions 1220. Each of the recessed regions 1220 can include at least one second suction opening 1215. For example, each recessed region 1220 can include a second suction opening 1215 positioned at or proximate a base of the respective recessed region 1220. The plurality of recessed regions 1220 can be positioned on or defined by the inner surface 1210 and positioned between the distal end and the proximal end of the suction element 1200. With the second suction opening 1215 position in the recessed region 1220 (e.g., at or proximate a base of the recessed region 1220), the second suction opening 1215 can be recessed or positioned inward relative to the inner surface 1210 and a remainder of the suction element 1200. Because the second suction opening 1215 is recessed relative to a remainder of the suction element 1200, the second suction opening 1215 can be unreachable or in a position that is difficult to reach by a tongue of a patient, for example. Consequently, because the tongue of the patient cannot easily reach the second suction opening 1215, the second suction opening 1215 is not easily occluded by the tongue of the patient. In some embodiments, the suction element 1200 can include two or more recessed regions 1220, each corresponding to a second suction opening 1215, where each of the recessed regions 1220 is separated by a wall 1225. For example, the inner surface 1210 can define a first recessed region 1220 and a second recessed region 1220. One second suction opening 1215 can be positioned within (e.g., at or proximate a base of) the first recessed region 1220, and another second suction opening 1215 can be positioned within (e.g., at or proximate a base of) the second recessed region 1220. The first recessed region 1220 and the second recessed region 1220 can be positioned on the inner surface 1210 of the suction element 1200, according to one embodiment. In another embodiment, the first recessed region 1220 can be positioned on the inner surface 1210, while the second recessed region 1220 can be positioned elsewhere (e.g., an opposite, outer surface) of the suction element 1200.474931 -5214-5527.2Atty.

[0152] FIG. 13, among others, depicts the second portion 110 of the oral medical device 100 is with a suction element 1300 (e.g., a suction portion, a suction paddle). The suction element 1300 includes at least one suction opening 1305 (e.g., an aperture 1305, a second opening 1305) fluidly coupled with the cavity 230 of the second portion 110. The cavity 230 can be positioned within the suction element 1300. The suction opening 1305 can be an opening through which irrigation fluid or other material (e.g., mucus, secretions, debris, or other material) can be drawn into the cavity 230 within the suction element 1300. For example, the suction element 1300 can be coupled with the second conduit 130, which can further be under vacuum pressure or negative pressure to draw the irrigation fluid and other material form the oral cavity of the patient and into the suction cavity 230 of the suction element 1300 to remove said irrigation fluid and other material from the oral cavity of the patient.

[0153] The suction element 1300 can include an inner surface 1310, a distal end portion 1315, and a proximal portion 1320. The inner surface 1310 can form the inner-most surface of the distal end portion 1315 and the proximal portion 1320. The distal end portion 1315 of the suction element 1300 can be an end or tip of the suction element 1300 that is positioned farthest within a patient’s oral cavity during operation of the oral medical device 100. The second conduit 130 can be coupled with the proximal portion 1320 of the suction element 1300, for example. The distal end portion 1315 and the proximal portion 1320 can collectively define the cavity 230 of the suction element 1300. For example, the distal end portion 1315 can be fluidly coupled with the proximal portion 1320. The distal end portion 1315 can be flexibly coupled with the proximal portion 1320. For example, the distal end portion 1315 can be coupled with the proximal portion 1320 and can pivot or flex about a joint 1325 relative to the proximal portion 1320. The distal end portion 1315 can flex inward toward the proximal portion 1320. For example, the portion of the inner surface 1310 of the distal end portion 1315 can pivot about the joint 1325 toward the portion of the inner surface 1310 of the proximal portion 1320. The distal end portion 1315 can fold toward the proximal portion 1320 about the joint 1325. The suction opening 1305 can be disposed proximate the distal end portion 1315 of the suction element 1300. In other examples, the suction element 1300 can include the suction opening 1305 positioned elsewhere, such as on the inner surface 1310 of the suction element 1300 or on some other surface of the suction element 1300. In yet other embodiments, the suction element 1300 can include multiple suction openings 1305 positioned in various positions on the suction element 1300.484931 -5214-5527.2Atty. Dkt: 139168-0149; SWF-008PCT

[0154] The suction element 1300 can include at least one actuator 1330 coupled with the distal end portion 1315. The actuator 1330 can receive a user input (e.g., an input provided by a medical care professional, the patient, or some other user). In response to the user input, the actuator 1330 can move the distal end portion 1315 relative to the proximal portion 1320. For example, in response to the user input, the actuator 1330 can cause the distal end portion 1315 of the suction element 1300 to move or flex in a first direction toward the proximal portion 1320 (e.g., from a first position to a second position). According to an exemplary embodiment, the distal end portion 1315 of the suction element 1300 can include a mounting feature 1340. The mounting feature 1340 can be a loop, a hook an opening, or some other coupling feature to which the actuator 1330 can mount or be otherwise coupled. For example, the actuator 1330 can be coupled with the mounting feature 1340. The mounting feature can be positioned on the inner surface 1310 of the distal end portion 1315. The actuator 1330 can be a wire, a tether, a cord, a cable, a rope, a strand, a rigid or flexible elongate member, or some other member. For example, the actuator 1330 can be a wire that is coupled with the mounting feature 1340 of the distal end portion 1315 and is configured to receive a tensile force applied by a user (e.g., the aforementioned user input) in a direction 1345. The tensile force can be a pulling or a tugging force, for example. In response to the tensile force, the actuator 1330 can apply a force to the mounting feature 1340 which, by virtue of its coupling to the distal end portion 1315, can cause the distal end portion 1315 to pivot about the joint 1325. The actuator 1330 can be or include a wire that can be coupled with silicone coating or some other material (e.g., some other soft material, antibacterial material, flexible material, rigid material, or some other material) at least partially surrounding or encapsulating the wire.

[0155] As depicted in FIG. 13, among others, the suction element 1300 can include a second actuator 1335. The second actuator 1335 can be coupled with a second mounting feature 1340 coupled with the distal end portion 1315. The second mounting feature 1340 can be coupled with an opposite side of the distal end portion 1315 as the mounting feature 1340 that is coupled with the actuator 1330. For example, the second actuator 1335 can received a user input (e.g., an input provided by a medical care professional, the patient, or some other user). In response to the user input, the second actuator 1335 can move the distal end portion 1315 relative to the proximal portion 1320. For example, in response to the user input, the second actuator 1335 can cause the distal end portion 1315 of the suction element 1300 to move or flex in a second direction away from the proximal portion 1320 (e.g., from the second position to a first position). The second actuator 1335 can be a wire, a tether, a cord, a cable, a494931 -5214-5527.2Atty. Dkt: 139168-0149; SWF-008PCT rope, a strand, a rigid or flexible elongate member, or some other member. For example, the second actuator 1335 can be a wire that is coupled with the mounting feature 1340 of the distal end portion 1315 and is configured to receive a tensile force applied by a user (e.g., the aforementioned user input) in the direction 1345. The tensile force can be a pulling or a tugging force, for example. In response to the tensile force, the second actuator 1335 can apply a force to the mounting feature 1340 which, by virtue of its coupling to the distal end portion 1315, can cause the distal end portion 1315 to pivot about the j oint 1325. The second actuator 1335 can be or include a wire that can be coupled with silicone coating or some other material (e.g., some other soft material, antibacterial material, flexible material, rigid material, or some other material) at least partially surrounding or encapsulating the wire.

[0156] The suction element 1300 can include the distal end portion 1315 that can selectively move (e.g., in response to a user input via the actuator 1330 or the second actuator 1335) to prevent or reduce the incidence of occlusion of the suction opening 1305. For example, movement of the distal end portion 1315 can alert a patient to the presence of the oral medical device and prompt the patient to move their tongue away from the suction element 1300 and thus away from the suction opening 1305. In other examples, movement of the distal end portion 1315 relative to the proximal portion 1320 can jostle, loosen, disperse, break apart, or otherwise move any mucus, secretions, debris, or other material that may build up at or proximate to the suction opening 1305. By moving to jostle, loosen, disperse, break apart, or otherwise move any mucus, secretions, debris, or other material near the suction opening 1305, a likelihood that the mucus, secretions, debris, or other material near the suction opening 1305 will at least partially occlude the suction opening 1305 can be reduced, thereby preserving or increasing the efficacy of the oral medical device 100.

[0157] FIG. 14, among others, depicts the second portion 110 of the oral medical device 100 is with a suction element 1400 (e.g., a suction portion, a suction paddle). The suction element 1400 includes at least one suction opening 1405 (e.g., an aperture 1405, a second opening 1405) fluidly coupled with the cavity 230 of the second portion 110. The cavity 230 can be positioned within the suction element 1400. The suction opening 1405 can be an opening through which irrigation fluid or other material (e.g., mucus, secretions, debris, or other material) can be drawn into the cavity 230 within the suction element 1400. For example, the suction element 1400 can be coupled with the second conduit 130, which can further be under vacuum pressure or negative pressure to draw the irrigation fluid and other material form504931 -5214-5527.2Atty. Dkt: 139168-0149; SWF-008PCT the oral cavity of the patient and into the suction cavity 230 of the suction element 1400 to remove said irrigation fluid and other material from the oral cavity of the patient.

[0158] The suction element 1400 can include an inner surface 1410, a distal end portion 1415, and a proximal portion 1420. The inner surface 1410 can form the inner-most surface of the distal end portion 1415 and the proximal portion 1420. The distal end portion 1415 of the suction element 1400 can be an end or tip of the suction element 1400 that is positioned farthest within a patient’s oral cavity during operation of the oral medical device 100. The second conduit 130 can be coupled with the proximal portion 1420 of the suction element 1400, for example. The distal end portion 1415 and the proximal portion 1420 can collectively define the cavity 230 of the suction element 1400. For example, the distal end portion 1415 can be fluidly coupled with the proximal portion 1420. The distal end portion 1415 can be rotatably coupled with the proximal portion 1420. For example, the distal end portion 1415 can be rotatably coupled with the proximal portion 1420 at a joint 1425 (e.g., a seam 1425 separating the distal end portion 1415 and the proximal portion 1420) and configured to move (e.g., rotate, spin, pivot, or otherwise move) relative to the proximal portion 1420. The distal end portion 1415 can rotate in a direction 1430 that can be a clockwise or a counter clockwise direction. The distal end portion 1415 can rotate in the direction 1430 relative to the proximal portion 1420 and be substantially prevented from rotating in a second direction opposite the direction 1430. For example, the distal end portion 1415 can be coupled with the proximal portion 1420 via a one-way ratchet mechanism or some other mechanism that permits rotation only in the direction 1430 but not in an opposite direction.

[0159] The suction opening 1405 can be disposed proximate the distal end portion 1415 of the suction element 1400. For example, the suction opening 1405 can be positioned radially on (e.g., around a periphery of) the distal end portion 1415. The suction element 1400 can include multiple suction openings 1405 spaced around a periphery of the distal end portion 1415, where each of the multiple suction openings 1405 can be spaced radially from each other, for example. In other examples, the suction element 1400 can include the suction opening 1405 positioned elsewhere, such as on the inner surface 1410 of the suction element 1400 or on some other surface of the suction element 1400. In yet other embodiments, the suction element 1400 can include multiple suction openings 1405 positioned in various positions on the suction element 1400.514931 -5214-5527.2Atty. Dkt: 139168-0149; SWF-008PCT

[0160] The distal end portion 1415 of the suction element 1400 can move (e.g., rotate, spin, pivot, swivel) relative to the proximal portion 1420 in response to an input. For example, the input can be a user input (e.g., an input provided by a medical care professional, a patient, or some other user) or a condition- or signal-based input (e.g., a negative pressure exceeding a predetermined threshold). In one example, the input can be a force applied to the distal end portion 1415 by a tongue of the patient, where contact between the tongue of the patient and the distal end portion 1415 can cause the distal end portion 1415 to rotate relative to the proximal portion 1420 into a different position where the suction opening 1405 is less likely to be occluded by the tongue of the patient. In other examples, the application of a negative pressure force within the cavity (e.g., ordinary operation of the second portion 110 of the oral medical device) can cause the distal end portion 1415 to move relative to the proximal portion 1420. For example, the input can be or include a pressure signal caused by an increase in magnitude of a negative pressure within the cavity 230 (e.g., a pressure spike or pulsation). In some examples, movement of fluid thorough the suction opening 1405 into the cavity 230 during operation of the second portion 110 can cause the irrigation fluid to pass over or contact baffle, fin, or blade within the cavity 230 that is operatively coupled with the distal end portion 1415, where contact between the irrigation fluid and the baffle, fin, or blade can impart a force on the baffle, fin, or blade that causes the distal end portion 1415 to rotate relative to the proximal portion 1420.

[0161] The suction element 1400 can include the distal end portion 1415 that can selectively rotate (e.g., in response to an input) to prevent or reduce the incidence of occlusion of the suction opening 1405. For example, movement of the distal end portion 1415 can alert a patient to the presence of the oral medical device and prompt the patient to move their tongue away from the suction element 1400 and thus away from the suction opening 1405. In other examples, movement of the distal end portion 1415 relative to the proximal portion 1420 can jostle, loosen, disperse, break apart, or otherwise move any mucus, secretions, debris, or other material that may build up at or proximate to the suction opening 1405. By moving to jostle, loosen, disperse, break apart, or otherwise move any mucus, secretions, debris, or other material near the suction opening 1405, a likelihood that the mucus, secretions, debris, or other material near the suction opening 1405 will at least partially occlude the suction opening 1405 can be reduced, thereby preserving or increasing the efficacy of the oral medical device 100.

[0162] FIG. 15, among others, depict the second portion 110 of the oral medical device 100524931 -5214-5527.2Atty. Dkt: 139168-0149; SWF-008PCT is with a suction element 1500 (e.g., a suction portion, a suction paddle). The suction element 1500 includes at least one suction opening 1505 (e.g., an aperture 1505, a second opening 1505) fluidly coupled with the cavity 230 of the second portion 110. The cavity 230 can be positioned within the suction element 1500. The suction opening 1505 can be an opening through which irrigation fluid or other material (e.g., mucus, secretions, debris, or other material) can be drawn into the cavity 230 within the suction element 1500. For example, the suction element 1500 can be coupled with the second conduit 130, which can further be under vacuum pressure or negative pressure to draw the irrigation fluid and other material form the oral cavity of the patient and into the suction cavity 230 of the suction element 1500 to remove said irrigation fluid and other material from the oral cavity of the patient.

[0163] The suction element 1500 can include an inner surface 1510, a distal end portion 1515, and a proximal portion 1520. The inner surface 1510 can form the inner-most surface of the distal end portion 1515 and the proximal portion 1520. The distal end portion 1515 of the suction element 1500 can be an end or tip of the suction element 1500 that is positioned farthest within a patient’s oral cavity during operation of the oral medical device 100. The second conduit 130 can be coupled with the proximal portion 1520 of the suction element 1500, for example. The distal end portion 1515 and the proximal portion 1520 can collectively define the cavity 230 of the suction element 1500. For example, the distal end portion 1515 can be fluidly coupled with the proximal portion 1520. The distal end portion 1515 can be a flexible portion of the suction element 1500. The proximal portion 1520 can be a rigid or semi-rigid portion of the suction element 1500. For example, the suction element 1500 can include a rigid (e.g., injection molded plastic) inner shell that forms the proximal portion 1520, but not the distal end portion 1515. The proximal portion 1520 include the rigid inner shell with or without some outer coating (e.g., an outer silicone coating). The distal end portion 1515 can be substantially without any rigid inner shell such that a substantial portion (e.g., at least 75%) of the distal end portion 1515 is comprised of flexible material. The flexible material can be an elastomeric material, a resilient material, or some other non-rigid or pliable material. The flexible material of the distal end portion 1515 can permit the distal end portion 1515 to flex, fold, expand, or collapse relative to the proximal portion 1520, flex, fold, expand, or collapse relative to itself, or otherwise flex, fold or expand. For example, the distal end portion 1515 can fold inward on itself and into the cavity 230 and at least partially within the proximal portion 1520. The suction opening 1505 can be disposed proximate the distal end portion 1515 of the suction element 1500. In other examples, the suction element 1500 can include the534931 -5214-5527.2Atty. Dkt: 139168-0149; SWF-008PCT suction opening 1505 positioned elsewhere, such as on the inner surface 1510 of the suction element 1500 or on some other surface of the suction element 1500. In yet other embodiments, the suction element 1500 can include multiple suction openings 1505 positioned in various positions on the suction element 1500.

[0164] The distal end portion 1515 of the suction element 1500 can move (e.g., flex, fold, expand, collapse, or otherwise move) relative to the proximal portion 1520. The distal end portion 1515 can move relative to the proximal portion 1520 in response to a signal or input (e.g., a user input). For example, the distal end portion 1515 can collapse at least partially toward the proximal portion 1520 in response to a negative pressure signal or force. The negative pressure signal or force can be a negative pressure signal or force beyond some threshold negative pressure. For example, a negative pressure within the cavity 230 can spike or increase in response to a partial or substantially complete occlusion of at least one of the suction openings 1505. The complete or partial occlusion of the suction opening 1505 can cause the negative pressure within the cavity 230 to spike, which can cause the distal end portion 1515 to move relative to (e.g., fold or collapse at least partially into) the proximal portion 1520 from a first position (e.g., an initial position) to a second position (e.g., a folded or collapsed position). When the negative pressure force (e.g., the negative pressure force or signal beyond some threshold) is removed, the distal end portion 1515 can move (e.g., unfold or spring back) relative to the proximal portion 1520 from the second position to the first position. For example, the distal end portion 1515 can be a resilient or elastic member with shape memory that can substantially return to its original shape.

[0165] The suction element 1500 can include the distal end portion 1515 that can selectively move (e.g., in response to a threshold negative pressure force or signal within the cavity 230) to prevent or reduce the incidence of occlusion of the suction opening 1505. For example, movement of the distal end portion 1515 relative to the proximal portion 1520 can jostle, loosen, disperse, break apart, or otherwise move any mucus, secretions, debris, or other material that may build up at or proximate to the suction opening 1505. By moving to jostle, loosen, disperse, break apart, or otherwise move any mucus, secretions, debris, or other material near the suction opening 1505, a likelihood that the mucus, secretions, debris, or other material near the suction opening 1505 will at least partially occlude the suction opening 1505 can be reduced, thereby preserving or increasing the efficacy of the oral medical device 100.

[0166] FIGS. 16A-16C, among others, depict the second portion 110 of the oral medical544931 -5214-5527.2Atty. Dkt: 139168-0149; SWF-008PCT device 100 is with a suction element 1600 (e.g., a suction portion, a suction paddle). The suction element 1600 includes two or more suction openings 1605 (e.g., an apertures 1605, second openings 1605) fluidly coupled with the cavity 230 of the second portion 110. The two or more suction openings 1605 can include a first inlet 1605 and a second inlet 1605. The cavity 230 can be positioned within the suction element 1600. The suction opening 1605 can be an opening through which irrigation fluid or other material (e.g., mucus, secretions, debris, or other material) can be drawn into the cavity 230 within the suction element 1600. For example, the suction element 1600 can be coupled with the second conduit 130, which can further be under vacuum pressure or negative pressure to draw the irrigation fluid and other material form the oral cavity of the patient and into the suction cavity 230 of the suction element 1600 to remove said irrigation fluid and other material from the oral cavity of the patient. The suction openings 1605 can be disposed proximate a distal end of the suction element 1600, where the distal end of the suction element 1600 can be an end or tip of the suction element 1600 that is positioned farthest within a patient’s oral cavity during operation of the oral medical device 100. The second conduit 130 can be coupled with a proximal end of the suction element 1600, for example. In other embodiments, the suction element 1600 can include one or more of the multiple suction openings 1605 positioned in various other positions on the suction element 1600 spaced apart from the distal end.

[0167] The suction element 1600 can include a flapper 1615 that is rotatably coupled with the suction element 1600 and positioned at least partially within the cavity 230. The flapper 1615 can be rotatably coupled with the suction element 1600 via a pin 1610 (e.g., an axle 1610, a rod 1610, or some other member). The flapper 1615 can include a first arm 1620 extending outwardly relative to the pin 1610 in a first direction. The flapper 1615 can include a second arm 1625 extending outwardly relative to the pin 1610 in a second direction that is different than the first direction. The first arm 1620 of the flapper 1615 can extend from the pin 1610 in the first direction toward the suction openings 1605. For example, the suction openings 1605 can be positioned on or proximate to the distal end of the suction element 1600, and the first arm 1620 of the flapper 1615 can extend toward the distal end. For example, the first arm 1620 of the flapper 1615 can selectively extend to one of the suction openings 1605 (e.g., the first inlet 1605 or the second inlet 1605) such that an outer end of the first arm 1620 can extend at least partially into the suction opening 1605, to an edge of the suction opening 1605, or at least partially through the suction opening 1605.554931 -5214-5527.2Atty.

[0168] The flapper 1615 can move (e.g., rotate, pivot, swivel, or otherwise move) between a first position 1635 (as depicted in FIG. 16 A), a second position 1645 (as depicted in FIG. 16B), and a third position 1655 (as depicted in FIG. 16C), among other positions. For example, the flapper 1615 can selectively move in response to an input (e.g., a user input) from the first position 1635 to the second position 1645, vice versa, or any position therebetween. The flapper 1615 can selectively move in response to an input (e.g., a user input) from the second position 1645 to the third position 1655, vice versa, or any position therebetween. In the first position 1635, the flapper 1615 can at least partially occlude (e.g., block, plug, obstruct, contact, or otherwise occlude) the first inlet 1605. In the second position 1645, the flapper 1615 can be positioned so as to not occlude (e.g., block, plug, obstruct, contact, or otherwise occlude) either of the first inlet 1605 or the second inlet 1605. In the third position 1655, the flapper 1615 can at least partially occlude (e.g., block, plug, obstruct, contact, or otherwise occlude) the second inlet 1605.

[0169] The suction element 1600 can include at least one actuator 1630 coupled with the second arm of the flapper 1615. The actuator 1630 can receive a user input (e.g., an input provided by a medical care professional, the patient, or some other user). In response to the user input, the actuator 1630 can move (e.g., rotate, pivot, swivel, or otherwise move) the flapper 1615 about the pin 1610. For example, in response to the user input, the actuator 1630 can cause the flapper 1615 of the suction element 1600 to move from one position to another. The actuator 1630 can be a wire, a tether, a cord, a cable, a rope, a strand, a rigid or flexible elongate member, or some other member. For example, the actuator 1630 can be a wire that is coupled with the second arm 1625 of the flapper 1615 in a position that is offset from an axis about which the flapper 1615 rotates. The actuator 1630 can receive a pulling force applied by a user (e.g., the aforementioned user input) in a direction 1640 or a pushing force the direction 1650 to move the flapper 1615. For example, the actuator 1630 can receive pulling force (e.g., a tensile force, a tugging force), that can cause the flapper 1615 to rotate relative to the pin 1610 in a first direction (e.g., a clockwise direction as shown in FIG. 16A). Likewise, the actuator 1630 can receive pushing force, that can cause the flapper 1615 to rotate relative to the pin 1610 in a second direction (e.g., a counter clockwise direction as shown in FIGS. 16B and 16C). The actuator 1630 can be or include a wire that can be coupled with silicone coating or some other material (e.g., some other soft material, antibacterial material, flexible material, rigid material, or some other material) at least partially surrounding or encapsulating the wire.564931 -5214-5527.2Atty. Dkt: 139168-0149; SWF-008PCT

[0170] The suction element 1600 can include the flapper 1615 that can selectively move (e.g., in response to a user input via the actuator 1630) to remove an occlusion of one of the first inlet 1605 or the second inlet 1605. For example, if some material (e.g., mucus, secretions, debris, or some other material) is lodged or stuck within the first inlet 1605, a user can apply a force to the actuator 1630 to move the flapper 1615 into the first position 1635 in which the first arm 1620 of the flapper 1615 can be at least partially within the first inlet 1605. The presence of the first arm 1620 of the flapper 1615 can dislodge the material from first inlet 1605 or break apart the material within the first inlet 1605, for example. If some material (e.g., mucus, secretions, debris, or some other material) is lodged or stuck within the second inlet 1605, a user can apply a force to the actuator 1630 to move the flapper 1615 into the third position 1655 in which the first arm 1620 of the flapper 1615 can be at least partially within the second inlet 1605. The presence of the first arm 1620 of the flapper 1615 can dislodge the material from second inlet 1605 or break apart the material within the first inlet 1605, for example.

[0171] The suction element 1600 can include the flapper 1615 that can selectively move (e.g., in response to a user input via the actuator 1630) to vary a negative pressure within the cavity 230 to create pressure spikes or pulsations. For example, the first arm 1620 of the flapper 1615 can at least partially occlude the first inlet 1605 with the flapper 1615 in the first position 1635. The first arm 1620 of the flapper 1615 can at least partially occlude the second inlet 1605 with the flapper 1615 in the third position 1655. Movement of the flapper 1615 from the first position 1635 to the third position 1655 and vice versa, particularly in rapid or short intervals, can cause negative pressure spikes or pulsations as each of the first inlet 1605 and the second inlet 1605 are temporarily occluded. Negative pressure spikes or pulsations within the cavity can jostle, loosen, disperse, break apart, or otherwise move any mucus, secretions, debris, or other material that may build up at or proximate to the first inlet 1605 or the second inlet 1605. By moving to jostle, loosen, disperse, break apart, or otherwise move any mucus, secretions, debris, or other material near the first inlet 1605 or the second inlet 1605, a likelihood that the mucus, secretions, debris, or other material near the first inlet 1605 or the second inlet 1605 will at least partially occlude the first inlet 1605 or the second inlet 1605 can be reduced, thereby preserving or increasing the efficacy of the oral medical device 100.

[0172] FIGS. 17-19, among others, depict the second portion 110 of the oral medical574931 -5214-5527.2Atty. Dkt: 139168-0149; SWF-008PCT device 100 is shown with a suction element 1700 (e.g., a suction portion, a suction paddle).The suction element 1700 can include at least one first suction opening 1705 (e.g., an aperture 1705, a second opening 1705) fluidly coupled with a first cavity 1715 of the second portion 110. The suction element 1700 can include at least one second suction opening 1710 (e.g., an aperture 1710, a second opening 1710) fluidly coupled with a second cavity 1720 of the second portion 110. The first cavity 1715 and the second cavity 1720 can be positioned within the suction element 1700 and separated by a partition 1735. For example, both of the first cavity 1715 and the second cavity 1720 can be formed within the suction element 1700 but separated by the partition 1735 such that the first cavity 1715 and the second cavity 1720 are not in fluid communication. The first suction opening 1705 and the second suction opening 1710 can each be an opening through which irrigation fluid or other material (e.g., mucus, secretions, debris, or other material) can be drawn into a respective cavity (e.g., the first cavity 1715 or the second cavity 1720) within the suction element 1700. For example, the suction element 1700 can be coupled with the second conduit 130, which can further be under vacuum pressure or negative pressure to draw the irrigation fluid and other material form the oral cavity of the patient and into the first cavity 1715 or the second cavity 1720 of the suction element 1700 to remove said irrigation fluid and other material from the oral cavity of the patient.

[0173] The suction element 1700 can include a first distal end portion 1703 (e.g., a first tip 1703, a first tip portion 1703), a second distal end portion 1707 (e.g., a second tip 1707, a second tip portion 1707) and a proximal portion 1727. The first distal end portion 1703 and the second distal end portion 1707 of the suction element 1500 can collectively be or form an end or tip of the suction element 1700 that is positioned farthest within a patient’s oral cavity during operation of the oral medical device 100. The second conduit 130 can be coupled with the proximal portion 1727 of the suction element 1700, for example. The first distal end portion 1703 and the proximal portion 1727 can collectively define the first cavity 1715 of the suction element 1700. For example, the first distal end portion 1703 can be fluidly coupled with the proximal portion 1727 via the first cavity 1715. The second distal end portion 1707 and the proximal portion 1727 can collectively define the second cavity 1720 of the suction element 1700. For example, the second distal end portion 1720 can be fluidly coupled with the proximal portion 1727 via the second cavity 1720.

[0174] The first distal end portion 1703 can be a flexible portion of the suction element 1700. The second distal end portion 1707 can be a flexible portion of the suction element584931 -5214-5527.2Atty. Dkt: 139168-0149; SWF-008PCT1700. For example, the proximal portion 1727 can be or include a rigid or semi-rigid portion of the suction element 1700. The suction element 1700 can include a rigid (e.g., injection molded plastic) inner shell that forms the proximal portion 1727, but not the first distal end portion 1703 or the second distal end portion 1707. The proximal portion 1727 include the rigid inner shell with or without some outer coating (e.g., an outer silicone coating). The first distal end portion 1703 and the second distal end portion 1707 can be substantially without any rigid inner shell such that a substantial portion (e.g., at least 75%) of the first distal end portion 1703 or the second distal end portion 1707 is comprised of flexible material. The flexible material can be an elastomeric material, a resilient material, or some other non-rigid or pliable material. The flexible material of the first distal end portion 1703 can permit the first distal end portion 1703 to flex, fold, expand, or collapse relative to the proximal portion 1727, flex, fold, expand, or collapse relative to itself, or otherwise flex, fold, expand, or collapse. For example, the first distal end portion 1703 can fold inward on itself and into the first cavity 1715 and at least partially within the proximal portion 1727. The flexible material of the second distal end portion 1707 can permit the second distal end portion 1707 to flex, fold, expand, or collapse relative to the proximal portion 1727, flex, fold, expand, or collapse relative to itself, or otherwise flex, fold, expand, or collapse. For example, the second distal end portion 1707 can fold inward on itself and into the second cavity 1720 and at least partially within the proximal portion 1727.

[0175] The first suction opening 1705 and the second suction opening 1710 can be disposed on a distal end of the suction element 1700, where the distal end of the suction element 1700 can be an end or tip of the suction element 1700 that is positioned farthest within a patient’s oral cavity during operation of the oral medical device 100. In other examples, the suction element 1700 can include the one or more of the first suction opening 1705 and the second suction opening 1710 positioned elsewhere on the suction element 1700, such as on an inner surface of the suction element 1700, on an outer surface of the suction element 1700, or some other surface of the suction element 1700. In yet other embodiments, the suction element 1700 can include multiple first suction openings 1705 or multiple second suction openings 1710 positioned in various positions on the suction element 1700.

[0176] The first distal end portion 1703 of the suction element 1700 can move (e.g., flex, fold, expand, collapse, or otherwise move) relative to the proximal portion 1727. The first distal end portion 1703 can move relative to the proximal portion 1727 in response to a signal594931 -5214-5527.2Atty. Dkt: 139168-0149; SWF-008PCT or input (e.g., a user input). For example, the first distal end portion 1703 can collapse at least partially toward the proximal portion 1727 and at least partially into the first cavity 1715 in response to a negative pressure signal or force. The second distal end portion 1707 of the suction element 1700 can move (e.g., flex, fold, expand, collapse, or otherwise move) relative to the proximal portion 1727. The second distal end portion 1707 can move relative to the proximal portion 1727 in response to a signal or input (e.g., a user input). For example, the second distal end portion 1707 can collapse at least partially toward the proximal portion 1727 and at least partially into the second cavity 1720 in response to a negative pressure signal or force. The negative pressure signal or force can be a negative pressure signal or force beyond some threshold negative pressure. For example, a negative pressure within the first cavity 1715 can spike or increase in response to a partial or substantially complete occlusion the first suction opening 1705. A negative pressure within the second cavity 1720 can spike or increase in response to a partial or substantially complete occlusion the second suction opening 1710. The complete or partial occlusion of a suction opening (e.g., the first suction opening 1705 or the second suction opening 1710) can cause the negative pressure within the respective cavity (e.g., the first cavity 1715 or the second cavity 1720) to spike, which can cause the respective distal end portion (e.g., the first distal end portion 1703 or the second distal end portion 1707) to move relative to (e.g., fold or collapse at least partially into) the proximal portion 1727 from a first position (e.g., an initial position) to a second position (e.g., a folded or collapsed position). When the negative pressure force (e.g., the negative pressure force or signal beyond some threshold) is removed from the respective cavity (e.g., the first cavity 1715 or the second cavity 1720), the respective distal end portion (e.g., the first distal end portion 1703 or the second distal end portion 1707) can move (e.g., unfold or spring back) relative to the proximal portion 1727 from the second position to the first position. For example, the first distal end portion 1703 and the second distal end portion 1707 can be a resilient or elastic member with shape memory that can substantially return to its original shape.

[0177] As depicted in FIGS. 17 and 27, among others, the suction element 1700 can include a first suction conduit portion 1725, a second suction conduit portion 1730, and an actuator 2700 (e.g., a valve 2700, pressure modulator 2700). The second conduit 130, the first suction conduit portion 1725, and the second suction conduit portion 1730 can be fluidly coupled with the actuator 2700. The actuator 2700, as depicted in FIG. 17 and again in FIG. 27, can selectively couple the first suction conduit portion 1725 with the second conduit 130. For example, the actuator 2700 can be or include one or more valves that can selectively fluidly604931 -5214-5527.2Atty. Dkt: 139168-0149; SWF-008PCT couple one or more of the first suction conduit portion 1725 and the second suction conduit portion 1730 with the second conduit 130. The first suction conduit portion 1725 can be fluidly coupled with the first cavity 1715. The second suction conduit portion 1730 can be fluidly coupled with the second cavity 1720. Accordingly, the actuator 2700 can include one or more valves that can move (e.g., in response to a user input) to selectively fluidly couple the first cavity 1715 with the second conduit 130 via the first suction conduit portion 1725. For example, the first cavity 1715 can be fluidly coupled with the second conduit 130 via the first suction conduit portion 1725 with the actuator 2700 in a first position. The actuator 2700 can include one or more valves that can move (e.g., in response to a user input) to selectively fluidly couple the second cavity 1720 with the second conduit 130 via the second suction conduit portion 1730. For example, the second cavity 1720 can be fluidly coupled with the second conduit 130 via the second suction conduit portion 1730 with the actuator 2700 in a first position. The actuator 2700 can include a rotatable switch 2705 to facilitate actuation of the actuator 2700. The switch 2705 can move rotate in a direction 2710 to actuate the actuator 2700, for example.

[0178] The actuator 2700 can be selectively actuated to alter a negative pressure within the first cavity 1715 or a negative pressure within the second cavity 1720 in response to a user input (e.g., an input from a medical care professional, the patient, or some other user). For example, movement of the actuator 2700 from the first position in which the first cavity 1715 is fluidly coupled with the second conduit 130 to the second position in which the second cavity 1720 is fluidly coupled with the second conduit 130 can vary a negative pressure within each of the first cavity 1715 and the second cavity 1720 to create pressure spikes or pulsations. Negative pressure spikes or pulsations within the cavity can jostle, loosen, disperse, break apart, or otherwise move any mucus, secretions, debris, or other material that may build up at or proximate to the first suction opening 1705 or the second suction opening 1710. By moving to jostle, loosen, disperse, break apart, or otherwise move any mucus, secretions, debris, or other material near the first suction opening 1705 or the second suction opening 1720, a likelihood that the mucus, secretions, debris, or other material near the first suction opening 1705 or the second suction opening 1710 will at least partially occlude the first suction opening 1705 or the second suction opening 1710 can be reduced, thereby preserving or increasing the efficacy of the oral medical device 100.

[0179] The suction element 1700 can include the first distal end portion 1703 and the614931 -5214-5527.2Atty. Dkt: 139168-0149; SWF-008PCT second distal end portion 1707 that can selectively move (e.g., in response to a threshold negative pressure force or signal within the first cavity 1715 or the second cavity 1720) to prevent or reduce the incidence of occlusion of the first suction opening 1705 or the second suction opening 1710. For example, movement of the first distal end portion 1703 relative to the proximal portion 1727 can jostle, loosen, disperse, break apart, or otherwise move any mucus, secretions, debris, or other material that may build up at or proximate to the first suction opening 1705. By moving to jostle, loosen, disperse, break apart, or otherwise move any mucus, secretions, debris, or other material near the first suction opening 1705, a likelihood that the mucus, secretions, debris, or other material near the first suction opening 1705 will at least partially occlude the first suction opening 1705 can be reduced, thereby preserving or increasing the efficacy of the oral medical device 100. The same concept can apply to the second suction opening 1710.

[0180] FIG. 20, among others, depicts the second portion 110 of the oral medical device 100 is with a suction element 2000 (e.g., a suction portion, a suction paddle). The suction element 2000 includes an inner surface 2010, an outer surface 2030, a top surface 2020, a bottom surface 2025, a distal end 2015, and multiple suction openings 2005 (e.g., an apertures 2005, second openings 2005, suction inlets 2005). The multiple suction openings 2005 can be fluidly coupled with the cavity 230 of the second portion 110. The cavity 230 can be positioned within the suction element 2000. The suction openings 2005 can each be an opening through which irrigation fluid or other material (e.g., mucus, secretions, debris, or other material) can be drawn into the cavity 230 within the suction element 2000. For example, the suction element 2000 can be coupled with the second conduit 130, which can further be under vacuum pressure or negative pressure to draw the irrigation fluid and other material form the oral cavity of the patient and into the suction cavity 230 of the suction element 2000 to remove said irrigation fluid and other material from the oral cavity of the patient.

[0181] The suction openings 2005 can be disposed on various of the inner surface 2010, the outer surface 2030, the top surface 2020, the bottom surface 2025, and the distal end 2015 of the suction element 2000. For example, the suction element 2000 can include at least one suction opening 2005 positioned on each of the inner surface 2010, the outer surface 2030, the top surface 2020, the bottom surface 2025, and the distal end 2015. In other examples, the suction element 2000 can include at least two suction openings 2005 positioned on each of the inner surface 2010, the outer surface 2030, the top surface 2020, the bottom surface 2025, and624931 -5214-5527.2Atty. Dkt: 139168-0149; SWF-008PCT the distal end 2015. The suction openings 2005 can be uniformly shaped or dimensioned. The suction openings 2005 can have varying shapes or dimensions. For example, the suction openings 2005 can include a first suction opening 2005 having a first dimension and a second suction opening 2005 having a second dimension, the first dimension different than the second dimension.

[0182] Because the suction element 2000 includes multiple suction openings 2005 positioned variously on the inner surface 2010, the outer surface 2030, the top surface 2020, the bottom surface 2025, and the distal end 2015 of the suction element 2000, a likelihood that substantially all of the suction openings 2005 will be simultaneously occluded is reduced. For example, in embodiments having only one or some small number of suction openings, it is more likely that all of the suction openings will be simultaneously occluded (e.g., by a single, large mass of mucus or some other debris). However, because the suction element 2000 includes suction openings 2005 positioned on each of the inner surface 2010, the outer surface 2030, the top surface 2020, the bottom surface 2025, and the distal end 2015, it is less likely that each of the suction openings 2005 can be simultaneously occluded or partially occluded by mucus, secretions, debris, a tongue of the patient, or some other object, for example.

[0183] FIG. 21, among others, depicts the second portion 110 of the oral medical device 100 is with a suction element 2100 (e.g., a suction portion, a suction paddle). The suction element 2100 includes at least one suction opening (not shown) and at least one cover 2105. The suction opening can be fluidly coupled with the cavity 230 of the second portion 110. The cavity 230 can be positioned within the suction element 2100. The suction openings can each be an opening through which irrigation fluid or other material (e.g., mucus, secretions, debris, or other material) can be drawn into the cavity 230 within the suction element 2100. For example, the suction element 2100 can be coupled with the second conduit 130, which can further be under vacuum pressure or negative pressure to draw the irrigation fluid and other material form the oral cavity of the patient and into the suction cavity 230 of the suction element 2100 to remove said irrigation fluid and other material from the oral cavity of the patient.

[0184] The cover 2105 can be a porous cover (e.g., a porous foam cover, a porous fibrous cover, or some other porous cover). The cover 2105 can be or include a flexible, soft, pliable, or other deformable material. The cover 2105 can be positioned on the suction element 2100634931 -5214-5527.2Atty. Dkt: 139168-0149; SWF-008PCT such that irrigation fluid or other material reaches the suction opening by first passing through the cover 2105. For example, the cover 2105 can be positioned over at least a portion of each of an inner surface, an outer surface, a top surface, a bottom surface, and a distal end of the suction element 2100. Because the suction element 2100 includes the cover 2105 positioned over the suction opening, it is not likely that the suction opening can be occluded. For example, the cover 2105 creates a multitude of passageways through which irrigation fluid or other material can pass. If one of said passageways becomes occluded, the irrigation fluid or other material can flow to the suction opening and into the cavity 230 by a different passageway. Furthermore, the cover 2105 acts to space any mucus, secretions, debris, tongue of the patient, or some other material at a distance away from the suction opening, which reduces the likelihood that the mucus, secretions, debris, tongue, or other material can be positioned close enough to the suction opening to partially or fully occlude the suction opening. The cover 2105 can also act as a strainer or filter. For example, because the cover 2105 defines a multitude of passageway by its porous nature, application of a negative pressure to draw irrigation fluid or other material through the cover 2105 can force the irrigation fluid or other material simultaneously through more than one passageway, which can effectively break apart any material (e.g., mucus, secretions, debris, or other material). With the material broken apart and therefore having a smaller dimension, the material can more readily flow through the suction opening and into the cavity 230 without occluding the suction opening.

[0185] FIGS. 22 and 23, among others, depicts the second portion 110 of the oral medical device 100 is with a suction element 2200 (e.g., a suction portion, a suction paddle). The suction element 2200 includes at least one suction opening 2205 (e.g., an aperture 2205, a second opening 2205) fluidly coupled with the cavity 230 of the second portion 110. The cavity 230 can be positioned within the suction element 2200. The suction opening 2205 can be an opening through which irrigation fluid or other material (e.g., mucus, secretions, debris, or other material) can be drawn into the cavity 230 within the suction element 2200. For example, the suction element 2200 can be coupled with the second conduit 130, which can further be under vacuum pressure or negative pressure to draw the irrigation fluid and other material form the oral cavity of the patient and into the suction cavity 230 of the suction element 2200 to remove said irrigation fluid and other material from the oral cavity of the patient. The suction opening 2205 can be disposed proximate a distal end of the suction element 2200, where the distal end of the suction element 2200 can be an end or tip of the suction element 2200 that is positioned farthest within a patient’s oral cavity during operation644931 -5214-5527.2Atty. Dkt: 139168-0149; SWF-008PCT of the oral medical device 100. The second conduit 130 can be coupled with a proximal end of the suction element 2200, for example. In other examples, the suction element 2200 can include the suction opening 2205 positioned elsewhere, such as on an inner surface 2210 of an outer member of the suction element 2200, or some other surface of the suction element 2200. In yet other embodiments, the suction element 2200 can include multiple suction openings 2205 positioned in various positions on the suction element 2200.

[0186] The suction element 2200 can include at least one fin 2215. The fin 2215 can extend from (e.g., protrude from, project from, stand proud relative to) the inner surface 2210 or some other surface of the suction element 2200. For example, the fin 2215 can extend from the inner surface 2210 toward the first portion 105 of the oral medical device 100. According to an exemplary embodiment, the suction element 2200 can include two or more fins 2215 that extend from an outer member (e.g., the inner surface 2210) of the suction element 2100. The two or more fins 2215 can be similarly or dissimilarly oriented. For example, each of the fins 2215 can be parallel or substantially parallel (e.g., ± 30°) relative to each other or at some angle relative to each other. The two or more fins 2215 can be similarly or dissimilarly dimensioned or shaped. For example, each of the fins 2215 can be substantially linear projections, as depicted in FIGS. 22 and 23, among others. In other examples, one or more of the fins 2215 can include some other shape (e.g., a non-linear or curved shape, an irregular shape, or some other shape).

[0187] The suction element 2200 can include the suction opening 2205 positioned between two fins 2215. For example, the suction paddle can include a fin 2215 positioned to one side (e.g., a right side) of the suction opening 2205 and another fin 2215 positioned to another side (e.g., a left side) of the suction opening 2205. In various embodiments, the suction element 2200 includes multiple suction openings 2205. For example, the suction element 2200 includes a first suction opening 2205 (e.g., a first inlet 2205) and a second suction opening 2205 (e.g., a second suction inlet 2205). The suction element 2200 can include a fin 2215 positioned between the first suction opening 2205 and the second suction opening 2205. In other embodiments, the suction element 2200 includes a first fin 2215 protruding from the inner surface 2210 (e.g., the outer member) and positioned between a first suction opening 2205 and a second suction opening 2205, as well as a second fin 2215 protruding from the inner surface 2210 (e.g., the outer member) and positioned between the second suction opening 2205 and a third suction opening 2205.654931 -5214-5527.2Atty. Dkt: 139168-0149; SWF-008PCT

[0188] The suction opening 2205 of the suction element 2200 can be recessed relative to an end of the fin 2215. For example, because the fin 2215 extends from the inner surface and because the suction opening 2205 can be positioned on the inner surface 2210 of the suction element 2200, the suction opening 2205 can be recessed relative to the fin 2215. With the suction opening 2205 in a recessed position relative to the fin 2215, the suction opening 2205 can be unreachable or in a position that is difficult to reach by a tongue of a patient, for example. Consequently, because the tongue of the patient cannot easily reach the suction opening 2205, the suction opening 2205 is not easily occluded by the tongue of the patient. In some embodiments, the suction element 2200 can include multiple suction openings 2205 that are each recessed relative to multiple fins 2215 to reduce the incidence of diminished efficacy of the second portion 110 by virtue of occlusion of the suction opening 2205 by a tongue of a patient, for example.

[0189] FIG. 24, among others, depicts the second portion 110 of the oral medical device 100 is with a suction element 2400 (e.g., a suction portion, a suction paddle). The suction element 2400 includes at least one suction opening 2405 (e.g., an aperture 2405, a second opening 2405) that is fluidly coupled with the cavity 230 of the second portion 110. The cavity 230 can be positioned within the suction element 2400. The suction opening 2405 can be an opening through which irrigation fluid or other material (e.g., mucus, secretions, debris, or other material) can be drawn into the cavity 230 within the suction element 2400. For example, the suction element 2400 can be coupled with the second conduit 130, which can further be under vacuum pressure or negative pressure to draw the irrigation fluid and other material form the oral cavity of the patient and into the suction cavity 230 of the suction element 2400 to remove said irrigation fluid and other material from the oral cavity of the patient. The suction opening 2405 can be disposed proximate a distal end of the suction element 2400, where the distal end of the suction element 2400 can be an end or tip of the suction element 2400 that is positioned farthest within a patient’s oral cavity during operation of the oral medical device 100. The second conduit 130 can be coupled with a proximal end of the suction element 2400, for example. In other examples, the suction element 2400 can include the suction opening 2405 positioned elsewhere, such as on an inner surface of the suction element 2400, or some other surface of the suction element 2400. In yet other embodiments, the suction element 2400 can include multiple suction openings 2405 positioned in various positions on the suction paddle 2405.664931 -5214-5527.2Atty. Dkt: 139168-0149; SWF-008PCT

[0190] The suction element 2400 can be fluidly coupled with the second conduit 130, where the second conduit 130 can include an actuator 2425 (e.g., pressure modulator 2425), as depicted in FIGS. 24 and 28, among others. The actuator 2425 can be a pressure actuator that is used to modulate or change a pressure within the cavity 230. The actuator 2425 can include a tube 2800 that extends from the second conduit 130. The tube 2800 can include a side wall 2805 and an opening 2810. For example, the actuator 2425 can be a thumb port or open orifice that, when plugged or occluded, causes a negative pressure within the cavity 230 to increase. For example, a user can position their thumb (or another finger or object) on an end of the tube 2800 against the perimeter of the wall 2805 to partially or completely block access to the opening 2810 of the tube 2800 (e.g., to plug the tube 2800). Plugging the tube 2800 can cause a negative pressure within the cavity 230 to increase. Removal of the user’s thumb or other object from the end of the tube 2800 can cause the negative pressure to reduce in magnitude. Accordingly, repeated plugging and unplugging of the actuator 2425 can cause a negative pressure within the cavity 230 to fluctuate or modulate. In various embodiments, the actuator 2425 can receive a user input (e.g., an input of a medical care professional, a patient, or some other user and, in response to the user input, create or change a negative pressure force within the cavity.

[0191] The suction element 2400 can include at least one jaw 2410. The jaw 2410 can be pivotally coupled with the suction element 2400 and positioned at least partially within the suction opening 2405. For example, the suction paddle 2405 can include two or more jaws 2410 that are pivotally connected at or proximate to the suction opening 2405 such that a portion of the jaw 2410 through the suction opening 2405 (e.g., out of the cavity 230). The jaw 2410 can include a first jaw portion 2415 and a second jaw portion 2420. The first jaw portion 2415 can be positioned out of the cavity 230, while the second jaw portion 2420 can be positioned at least partially within the cavity 230. The jaw 2410 can be pivotally coupled with the suction element 2400 at some positioned between the first jaw portion 2415 and the second jaw portion 2420. A movement of the second jaw portion 2420 in one direction can cause an opposite movement of the first jaw portion 2415 because the jaw 2410 is pivotally coupled with the suction element 2400 at some position between the first jaw portion 2415 and the second jaw portion 2420. The suction element 2400 can include a first jaw 2410 and a second jaw 2410. The first jaw 2410 and the second jaw 2410 can each respectively include a first jaw portion 2415 and a second jaw portion 2420. The first jaw portion 2415 of the first jaw 2410 and the first jaw portion 2415 of the second jaw 2410 can extend from the suction element674931 -5214-5527.2Atty. Dkt: 139168-0149; SWF-008PCT2400. The first jaw portion 2415 of the first jaw 2410 and the first jaw portion 2415 of the second jaw 2410 can be substantially aligned such that the first jaw portion 2415 of the first jaw 2410 and the first jaw portion 2415 of the second jaw 2410 can contact each other. The second jaw portion 2420 of the first jaw 2410 and the second jaw portion 2420 of the second jaw 2410 can be positioned at least partially within the cavity 230.

[0192] The jaw 2415 can pivot relative to the suction element 2400 in response to the negative pressure force or a fluctuation of a negative pressure within the cavity 230 of the suction element 2400. For example, a change in negative pressure within the cavity 230 via actuation of the actuator 2425 can cause the second jaw portion 2420 of the jaw 2410 to move toward an inner wall of the suction element 2400 within the cavity 230. The movement of the second jaw portion 2420 of the jaw 2410 can correspondingly cause the first jaw portion 2415 to move. For example, in embodiments where the suction element 2400 includes a first jaw 2410 and a second jaw 2410, the first jaw portion 2415 of the first jaw 2410 can move toward the first jaw portion 2415 of the second jaw 2410 in response to a change in the negative pressure force. Specifically, the change in the negative pressure force within the cavity 230 can cause the second jaw portion 2420 of both the first jaw 2410 and the second jaw 2410 to move outward (e.g., towards an inner wall within the cavity 230) such that the first jaw portion 2415 of both the first jaw 2410 and the second jaw 2410 move toward each other. The movement of the first jaw portion 2415 of the first jaw 2140 toward the first jaw portion 2415 of the second jaw 2410 can mash, crush, or break apart, any material positioned between the first jaw portion 2415 of the first jaw 2140 toward the first jaw portion 2415 of the second jaw 2410. For example, any mucus, secretions, debris, or other material positioned at or proximate to the suction opening 2405 can be contacted by the first jaw 2410 and the second jaw 2410 to remove or reduce the incidence of any occlusion, for example. Furthermore, movement or pulsation of the first jaw 2410 during a suction operation can cause jostle, break free, loosen, or otherwise facilitate the movement of any material (e.g., mucus, secretions, debris, or other material) that may be positioned at or proximate to the suction opening 2405. In various embodiments, movement of the jaws 2410 can substantially prevent or reduce the incidence of occlusions of the suction opening 2405 to maintain a desired level of efficacy of the suction element 2400, for example.

[0193] FIGS. 25 and 26, among others, depict the second portion 110 of the oral medical device 100 is with a suction element 2500 (e.g., a suction portion, a suction paddle). The684931 -5214-5527.2Atty. Dkt: 139168-0149; SWF-008PCT suction element 2500 includes at least one suction opening 2605 (e.g., an apertures 2605, second openings 2605) fluidly coupled with the cavity 230 of the second portion 110. The cavity 230 can be positioned within the suction element 2500. The suction opening 2605 can be an opening through which irrigation fluid or other material (e.g., mucus, secretions, debris, or other material) can be drawn into the cavity 230 within the suction element 2500. For example, the suction element 2500 can be coupled with the second conduit 130, which can further be under vacuum pressure or negative pressure to draw the irrigation fluid and other material form the oral cavity of the patient and into the suction cavity 230 of the suction element 2500 to remove said irrigation fluid and other material from the oral cavity of the patient. The suction openings 2605 can be disposed proximate a distal end of the suction element 2500, where the distal end of the suction element 2500 can be an end or tip of the suction element 2500 that is positioned farthest within a patient’s oral cavity during operation of the oral medical device 100. The second conduit 130 can be coupled with a proximal end of the suction element 2500, for example. In other embodiments, the suction element 2500 can include the suction opening 2605 positioned some other position on the suction element 2500 spaced apart from the distal end.

[0194] The suction element 2500 can include an element 2505 (e.g., a spinning element 2505, a rotatable element 2505) that is rotatably coupled with the suction element 2500 and positioned at least partially within the cavity 230. The element 2505 can be rotatably coupled with the suction element 2500 via a pin 2510 (e.g., an axle 2510, a rod 2510, or some other member). The element 2505 can include at least one fin 2515 (e.g., a projection 2515) that can extend radially outward relative to the pin 2510. For example, the element 2505 can include multiple fins 2515 extending radially outward from the element 2505 in various directions. The element 2505 can be positioned at or proximate to the suction opening 2605. For example, the pin 2510 can be positioned within the cavity 230 in a location that is proximate to the suction opening 2605. The fin 2515 of the element 2505 can extend toward the suction opening 2605. For example, the fin 2515 can momentarily (e.g., depending upon a rotational position of the element 2505) extend at least partially through the suction opening 2605. The fin 2515 of the element 2505 can approach an edge of the suction opening 2605 to momentarily reduce a size of the suction opening 2605.

[0195] The element 2505 can move (e.g., rotate, pivot, swivel, or otherwise move) in a direction 2520 as irrigation fluid or other material (e.g., mucus, secretions, debris, or other694931 -5214-5527.2Atty. Dkt: 139168-0149; SWF-008PCT material) flows through the suction opening 2605 into the cavity 230. For example, the suction element 2500 can include the element 2505 that can move as irrigation fluid or other material moves into the cavity through the suction opening 2605 and around the element 2505 and the fin 2515 of the element 2505. In other examples, a negative pressure force within the cavity 230 can cause the element 2505 to rotate (e.g., with or without the passage of irrigation fluid past the element 2505). The element 2505 can move in the direction 2520 and can be substantially prevented from rotating in an opposite direction via a one-way ratchet mechanism or some other mechanism. Movement of the element 2505, namely movement of the fin 2515 in close proximity to the suction opening 2605 in rapid or short intervals, can cause negative pressure spikes or pulsations to occur within the cavity 230. Negative pressure spikes or pulsations within the cavity can jostle, loosen, disperse, break apart, or otherwise move any mucus, secretions, debris, or other material that may build up at or proximate to the suction opening 2605. By moving to jostle, loosen, disperse, break apart, or otherwise move any mucus, secretions, debris, or other material near suction opening 2605, a likelihood that the mucus, secretions, debris, or other material near the suction opening 2605 will at least partially occlude the suction opening 2605 can be reduced, thereby preserving or increasing the efficacy of the oral medical device 100. In addition, contact between the fin 2515 and the mucus, secretions, debris, or other material as such material passes through the suction opening 2605 and past the element 2505 can break apart, loosen, pulverize, or otherwise disperse the material so that the material more readily passes through the suction opening 2605 and into the cavity 230.

[0196] FIG. 29, among others, depicts the second portion 110 of the oral medical device 100 having a suction element 2900 (e.g., a suction portion, a suction paddle). The suction element 2900 includes at least one suction opening 2905 (e.g., an aperture 2905, a second opening 2905) fluidly coupled with the cavity 230 of the second portion 110. The cavity 230 can be positioned within the suction element 2900. The suction opening 2905 can be an opening through which irrigation fluid or other material (e.g., mucus, secretions, debris, or other material) can be drawn into the cavity 230 within the suction element 2900. For example, the suction element 2900 can be coupled with the second conduit 130, which can further be under vacuum pressure or negative pressure to draw the irrigation fluid and other material form the oral cavity of the patient and into the suction cavity 230 of the suction element 2900 to remove said irrigation fluid and other material from the oral cavity of the patient. The suction opening 2905 can be disposed on a distal end of the suction element 2900, where the distal end704931 -5214-5527.2Atty. Dkt: 139168-0149; SWF-008PCT of the suction element 2900 can be an end or tip of the suction element 2900 that is positioned farthest within a patient’s oral cavity during operation of the oral medical device 100. The second conduit 130 can be coupled with a proximal end of the suction element 2900, for example. In other examples, the suction element 2900 can include the suction opening 2905 positioned elsewhere, such as on an inner surface of the suction element 2900, an outer surface of the suction element 2900, or some other surface of the suction element 2900. The suction element 2900 can include at least one second suction opening 2910. The second suction opening 2910 can be an opening through which irrigation fluid or other material (e.g., mucus, secretions, debris, or other material) can be drawn into the cavity 230 within the suction element 2900. The second suction opening 2910 can be positioned on an inner surface of the suction element 2900 and spaced apart from the suction opening 2905, as shown in FIG. 29, among others. In other embodiments, the second suction opening 2910 can be positioned elsewhere on the suction element 2900.

[0197] One or more of the suction opening 2905 and the second suction opening 2910 can be a one-way valve. For example, the suction opening 2905 or the second suction opening 2910 can permit irrigation fluid or other material (e.g., mucus, secretions, debris, or other material to flow into the cavity 230, but not out of the cavity 230. In other examples, one or more of the suction opening 2905 and the second suction opening 2910 can be a pressure- actuated valve. For example, the suction opening 2905 and the second suction opening 2910 can be or include a flap that is normally closed (e.g., sealed against the suction element 2900 such that irrigation fluid or other material cannot pass through). When sufficient negative pressure occurs within the cavity 230 such that a sufficient pressure differential exists between the cavity 230 and a patient’s oral cavity, the suction opening 2905 or the second suction opening 2910, as the case may be, can open to permit irrigation fluid or other material (e.g., mucus, secretions, debris, or other material to flow into the cavity 230. In some examples, the second suction opening 2910 can be an opening providing free passage into the cavity 230 (e.g., the second suction opening 2910 can be without any flap or closure mechanism). The first suction opening 2905 can be a pressure-actuated valve. In the event the second suction opening 2910 becomes occluded, negative pressure within the cavity 230 can build, where the negative pressure can be sufficient to cause the first suction opening 2905 to open and allow irrigation fluid or other material to flow therethrough. Accordingly, the suction element 2900 can include one or more dynamic openings that can selectively open or close based on a pressure within the cavity 230.714931 -5214-5527.2Atty. Dkt: 139168-0149; SWF-008PCT

[0198] FIGS. 30A-30D, among others, depicts the second portion 110 of the oral medical device 100 having a suction element 3000 (e.g., a suction portion, a suction paddle). The suction element 3000 includes at least two suction openings 3005 (e.g., apertures 3005, second openings 3005) that are fluidly coupled with the cavity 230 of the second portion 110. The cavity 230 can be positioned within the suction element 3000. The suction openings 3000 can be openings through which irrigation fluid or other material (e.g., mucus, secretions, debris, or other material) can be drawn into the cavity 230 within the suction element 3000. For example, the suction element 3000 can be coupled with the second conduit 130, which can further be under vacuum pressure or negative pressure to draw the irrigation fluid and other material form the oral cavity of the patient and into the suction cavity 230 of the suction element 3000 to remove said irrigation fluid and other material from the oral cavity of the patient. The suction openings 3005 can be disposed on a distal end of the suction element 3000, where the distal end of the suction element 3000 can be an end or tip of the suction element 3000 that is positioned farthest within a patient’s oral cavity during operation of the oral medical device 100. The second conduit 130 can be coupled with a proximal end of the suction element 3000, for example. In other examples, the suction element 3000 can include the suction openings 3005 positioned elsewhere, such as on an inner surface 3010 of the suction element 3000, an outer surface of the suction element 3000, or some other surface of the suction element 3000.

[0199] The suction element 3000 can include at least one movable member 3020, as depicted in FIGS. 30A, 30B, and 30D, among others. The movable member 3020 can define a flow passage 3015. The movable member 3020 can move in a first direction 3025 or a second direction 3030, where the first direction 3025 and the second direction 3030 can be substantially opposite directions. The movable member 3020 can be positioned at least partially within the cavity 230 and can selectively extend through a first of the suction openings 3005 or a second of the suction openings 3005. When the movable member is positioned within a first suction opening 3005 (e.g., a suction opening 3005 opposite a tongue of the patient), as is depicted in FIG. 30D and as may occur when a second suction opening 3005 (e.g., a suction opening 3005 proximate the tongue of the patient) is occluded by a tongue 3035 of a patient or otherwise, irrigation fluid or other material can flow through the flow passage 3015 of the movable member 3020 and into the cavity 230. For example, the movable member 3020 can move in the direction 3025 when the second suction opening 3005 is occluded by a tongue of the patient or some other object in order to open the flow passage 3015 on an opposite side of the suction element 3000, as depicted in FIGS. 30A and 30B, among others. In724931 -5214-5527.2Atty. Dkt: 139168-0149; SWF-008PCT some examples, if an occlusion occurs in first of the suction openings 3005 (e.g., a suction opening 3005 opposite a tongue of the patient), the movable member 3020 can move in the direction 3030 and be positioned within the second suction opening 3005 (e.g., the suction opening 3005 proximate the tongue of the patient) so that the flow passage 3015 of the movable member 3020 is open on the non-occluded side of the suction element 3000. In this way, the movable member provides a dynamic or movable suction window or flow passage so provide a viable flow passage even when one side of the suction element 3000 is occluded, for example.

[0200] FIGS 31 and 32, among others, depict the second portion 110 of the oral medical device 100 is with a suction element 3100 (e.g., a suction portion, a suction paddle). The suction element 3100 includes at least one suction opening 3105 (e.g., an aperture 3105, a second opening 3105) fluidly coupled with the cavity 230 of the second portion 110. The cavity 230 can be positioned within the suction element 3100. The suction opening 3105 can be an opening through which irrigation fluid or other material (e.g., mucus, secretions, debris, or other material) can be drawn into the cavity 230 within the suction element 3100. For example, the suction element 3100 can be coupled with the second conduit 130, which can further be under vacuum pressure or negative pressure to draw the irrigation fluid and other material form the oral cavity of the patient and into the suction cavity 230 of the suction element 3100 to remove said irrigation fluid and other material from the oral cavity of the patient.

[0201] The suction element 3100 can include an inner surface, a distal end portion 3120, and a proximal portion 3110. The inner surface can form the inner-most surface of the distal end portion 3120 and the proximal portion 3110. The distal end portion 3120 of the suction element 3100 can be an end or tip of the suction element 3100 that is positioned farthest within a patient’s oral cavity during operation of the oral medical device 100. The distal end portion 3120 can define a second suction opening 3115. The second conduit 130 can be coupled with the proximal portion 3110 of the suction element 3100, for example. The distal end portion 3120 and the proximal portion 3110 can collectively define the cavity 230 of the suction element 3100. For example, the distal end portion 3120 can be fluidly coupled with the proximal portion 3110. The distal end portion 3120 can be a flexible portion of the suction element 3100. The proximal portion 3110 can be a rigid or semi-rigid portion of the suction element 3100. For example, the suction element 3100 can include a rigid (e.g., injection734931 -5214-5527.2Atty. Dkt: 139168-0149; SWF-008PCT molded plastic) inner shell that forms the proximal portion 3110, but not the distal end portion 3120. The proximal portion 3110 include the rigid inner shell with or without some outer coating (e.g., an outer silicone coating). The distal end portion 3120 can be substantially without any rigid inner shell such that a substantial portion (e.g., at least 75%) of the distal end portion 3120 is comprised of flexible material. The flexible material can be an elastomeric material, a resilient material, or some other non-rigid or pliable material. The flexible material of the distal end portion 3120 can permit the distal end portion 3120 to flex, open, fold, expand, collapse, or otherwise move. For example, the distal end portion 3120 can include the second suction opening 3115 that can selectively open to provide an additional or alternative flow passage into the cavity 230 of the suction element 3100. Like the second suction opening 3115, the suction opening 3105 can be disposed proximate the distal end portion 3120 of the suction element 3100. In other examples, the suction element 3100 can include the suction opening 3105 positioned elsewhere, such as on the inner surface of the suction element 3100 or on some other surface of the suction element 3100. In yet other embodiments, the suction element 3100 can include multiple suction openings 3105 or second suction openings 3115 positioned in various positions on the suction element 3100.

[0202] The distal end portion 3120 of the suction element 3100 can move (e.g., flex, fold, expand, collapse, or otherwise move) in response to a negative pressure signal or force within the cavity 230 of the suction element 3100. The negative pressure signal or force can be a negative pressure signal or force beyond some threshold negative pressure. For example, a negative pressure within the cavity 230 can spike or increase in response to a partial or substantially complete occlusion of at least one of the suction openings 3105. The complete or partial occlusion of the suction opening 3105 can cause the negative pressure within the cavity 230 to spike, which can cause the second suction opening 3115 positioned on the distal end portion 3120 to move to move from a closed position (as depicted in FIG. 31) to an open position (as depicted in FIG. 32). When the negative pressure force (e.g., the negative pressure force or signal beyond some threshold) is removed, the second suction opening 3115 on the distal end portion 3120 can move (e.g., unfold or spring back) from the open position to the closed position. For example, the distal end portion 3120 can be a resilient or elastic member with shape memory that can substantially return to its original shape with the second suction opening 3115 closed. In other examples, the second suction opening 3115 can open in response to a force applied to the distal end portion 3120 of the suction element 3100, such as a force applied by a tongue of a patient.744931 -5214-5527.2Atty.

[0203] The suction element 3100 can include the distal end portion 3120 having the second suction opening 3115 that can selectively open to prevent or reduce the incidence of an occlusion of the suction opening 3105 adversely affecting the efficacy or performance of the second portion 110. For example, selective opening of the second suction opening 3115 can provide an additional or alternative flow passage for irrigation fluid or other material (e.g., mucus, secretions, debris, or other material) in the event the first suction opening 3105 becomes occluded.

[0204] FIGS. 33 and 34, among others, depict the second portion 110 of the oral medical device 100 is with a suction element 3300 (e.g., a suction portion, a suction paddle). The suction element 3300 includes at least one first suction opening 3305 (e.g., an aperture 3305, a second opening 3305) fluidly coupled with the cavity 230 of the second portion 110. The suction element 3300 includes at least one second suction opening 3315 that can be selectively opened to be fluidly coupled with the cavity 230 of the second portion 110. The cavity 230 can be positioned within the suction element 3300. The suction opening 3305 can be an opening through which irrigation fluid or other material (e.g., mucus, secretions, debris, or other material) can be drawn into the cavity 230 within the suction element 3300. For example, the suction element 3300 can be coupled with the second conduit 130, which can further be under vacuum pressure or negative pressure to draw the irrigation fluid and other material form the oral cavity of the patient and into the suction cavity 230 of the suction element 3300 to remove said irrigation fluid and other material from the oral cavity of the patient.

[0205] The suction element 3300 can include an inner surface 3310 and an outer surface 3320, where the outer surface 3320 can be positioned proximate a cheek of the patient and the inner surface 3310 can be positioned proximate a tongue of the patient with the oral medical device 100 inserted into the patient’s oral cavity, for example. The first suction opening 3305 can be positioned on the inner surface 3310 of the suction element 3300. The second suction opening 3315 can be positioned on the outer surface 3320. The first suction opening 3305 and the second suction opening 3315 can be positioned at or proximate to a distal end of the suction element 3300, where the distal end of the suction element 3300 can be an end or tip of the suction element 2200 that is positioned farthest within a patient’s oral cavity during operation of the oral medical device 100. The second conduit 130 can be coupled with a proximal end of the suction element 3300, for example. In other examples, the suction element 3300 can include the first suction opening 3305 and the second suction opening 3315 positioned754931 -5214-5527.2Atty. Dkt: 139168-0149; SWF-008PCT elsewhere, such as on the inner surface 3310 of the suction element 3300, an outer surface 3320 of the suction element 3300, or some other surface of the suction element 3300.

[0206] The suction element 3300 can be or include a flexible, soft, pliable, or other material. For example, an entirety or a substantial portion (e.g., >50%) of the suction element 3300 can include a flexible material that can be an elastomeric material, a resilient material, or some other non-rigid or pliable material. The flexible material of the suction element 3300 can permit the movement of the suction element 3300. For example, a distal end of the suction element 3300 can move toward a center of the patient’s oral cavity. For example, if the first suction opening 3305 of the suction element 3300 becomes occluded by a tongue 3410 of the patient, suction can force can be applied to the patient’s tongue 3410 to seal the first suction opening 3305 of the suction element 3300 over a portion of the tongue 3410 of the patient, thereby drawing the distal end of the suction element 3300 toward the center of the patient’s oral cavity in the direction 3400, for example. Movement of the distal end of the suction element 3300 toward the center of the patient’s oral cavity when the first suction opening 3305 is occluded by the patient’s tongue 3410 can cause the second suction opening 3405 to open, thereby providing an alternative flow passage into the cavity 230. For example, a portion of the distal end of the suction element 3300 can move in the direction 3405 to open the second suction opening 3315, as depicted in FIG. 34.

[0207] The suction element 3300 can move (e.g., flex, fold, expand, collapse, or otherwise move) in response to a negative pressure signal or force within the cavity 230 of the suction element 3300. The negative pressure signal or force can be a negative pressure signal or force beyond some threshold negative pressure. For example, a negative pressure within the cavity 230 can spike or increase in response to a partial or substantially complete occlusion of the first suction opening 3305 (e.g., occlusion by the tongue 3410 of the patient). The complete or partial occlusion of the first suction opening 3305 can cause the negative pressure within the cavity 230 to increase, which can cause the distal end of the suction element 3300 to move in the direction 3400 toward the center of the patient’s oral cavity. Movement of the distal end of the suction element 3300 in the direction 3400 can cause the second suction opening 3315 positioned on the outer surface 3320 of the suction element 3300 to open, as depicted in FIG. 34, among others. When the negative pressure force (e.g., the negative pressure force or signal beyond some threshold) is removed, as may occur when the occlusion of the first suction opening 3305 is removed, the second suction opening 3315 on outer surface 3320 can close764931 -5214-5527.2Atty. Dkt: 139168-0149; SWF-008PCT(e.g., spring back to its original position), and irrigation fluid or other material can flow through the first suction opening 3305. For example, the suction element 3300 can be or include can be a resilient or elastic material with shape memory that can substantially return to its original shape with the second suction opening 3315 closed. The suction element 3300 can include the second suction opening 3315 to dynamically open upon occlusion of the first suction opening 3305 in order to prevent or reduce the incidence of an occlusion of the suction opening 3305 adversely affecting the efficacy or performance of the second portion 110. For example, selective opening of the second suction opening 3315 can provide an additional or alternative flow passage for irrigation fluid or other material (e.g., mucus, secretions, debris, or other material) in the event the first suction opening 3305 becomes occluded.

[0208] FIGS. 35-37, among others, depict the second portion 110 of the oral medical device 100 having a suction element 3500 (e.g., a suction portion, a suction paddle). The suction element 3500 includes at least one suction opening 3505 (e.g., an aperture 3505, a second opening 3505) fluidly coupled with the cavity 230 of the second portion 110. The cavity 230 can be positioned within the suction element 3500. The suction opening 3505 can be an opening through which irrigation fluid or other material (e.g., mucus, secretions, debris, or other material) can be drawn into the cavity 230 within the suction element 3500. For example, the suction element 3500 can be coupled with the second conduit 130, which can further be under vacuum pressure or negative pressure to draw the irrigation fluid and other material form the oral cavity of the patient and into the suction cavity 230 of the suction element 3500 to remove said irrigation fluid and other material from the oral cavity of the patient. The suction opening 3505 can be disposed on a distal end of the suction element 3500, where the distal end of the suction element 3500 can be an end or tip of the suction element 3500 that is positioned farthest within a patient’s oral cavity during operation of the oral medical device 100. The second conduit 130 can be coupled with a proximal end of the suction element 3500, for example. In other examples, the suction element 3500 can include the suction opening 3505 positioned elsewhere, such as on an inner surface 3510 of the suction element 3500, an outer surface of the suction element 2900, or some other surface of the suction element 3500.

[0209] The suction element 3500 can include at least one second suction opening 3515. The second suction opening 3515 can be an opening through which irrigation fluid or other material (e.g., mucus, secretions, debris, or other material) can be drawn into the cavity 230774931 -5214-5527.2Atty. Dkt: 139168-0149; SWF-008PCT within the suction element 3500. The second suction opening 3515 can be positioned on an inner surface of the suction element 3500 and spaced apart from the suction opening 3505, as shown in FIG. 35, among others. In other embodiments, the second suction opening 3515 can be positioned elsewhere on the suction element 3500.

[0210] The second suction opening 3515 can be a one-way valve. For example, the second suction opening 3515 can permit irrigation fluid or other material (e.g., mucus, secretions, debris, or other material to flow into the cavity 230, but not out of the cavity 230. In other examples, the second suction opening 3515 can be a pressure-actuated valve. For example, the second suction opening 3515 can be or include at least one flap 3600 that is normally closed (e.g., sealed against some other part of the suction element 3500 such that irrigation fluid or other material cannot pass through). As depicted in FIGS. 36 and 37, the second suction opening 3515 can include two flaps 3600 that contact each other at a sealing portion 3605 to close the second suction opening 3515. When sufficient negative pressure occurs within the cavity 230 such that a sufficient pressure differential exists between the cavity 230 and a patient’s oral cavity, the second suction opening 3515 can open to permit irrigation fluid or other material (e.g., mucus, secretions, debris, or other material to flow into the cavity 230. For example, when sufficient negative pressure occurs within the cavity 230 such that a sufficient pressure differential exists between the cavity 230 and a patient’s oral cavity, the sealing portion 3605 the flaps 3600 can separate to open the second suction opening 3515 to create a passageway 3700 such that irrigation fluid or other material can flow through the passageway 3700 of the second suction opening 3515 into the cavity 230. In the event the first suction opening 3505 becomes occluded, negative pressure within the cavity 230 can build, where the negative pressure can be sufficient to cause the second suction opening 3515 to open and allow irrigation fluid or other material to flow therethrough. Accordingly, the suction element 3500 can include one or more dynamic openings that can selectively open or close based on a pressure within the cavity 230.

[0211] FIGS. 38 and 39, among others, depict the second portion 110 of the oral medical device 100 having a suction element 3800 (e.g., a suction portion, a suction paddle). The suction element 3800 includes at least one suction opening 3805 (e.g., an aperture 3805, a second opening 3805) fluidly coupled with the cavity 230 of the second portion 110. The cavity 230 can be positioned within the suction element 3800. The suction opening 3805 can be an opening through which irrigation fluid or other material (e.g., mucus, secretions, debris,784931 -5214-5527.2Atty. Dkt: 139168-0149; SWF-008PCT or other material) can be drawn into the cavity 230 within the suction element 3800. For example, the suction element 3800 can be coupled with the second conduit 130, which can further be under vacuum pressure or negative pressure to draw the irrigation fluid and other material form the oral cavity of the patient and into the suction cavity 230 of the suction element 3800 to remove said irrigation fluid and other material from the oral cavity of the patient.

[0212] The suction element 3800 can be a flexible or extendable member. For example, the suction element 3800 can include multiple ridges 3810 and valleys formed therebetween in an accordion-style configuration. The suction element 3800 can include an initial position with the suction element 3800 in an extended state. When subject to negative pressure within the cavity 230 beyond some threshold negative pressure, the suction element 3800 can move in the direction 3900 from the initial position in the extended state to a second position in a retracted state, as depicted in FIG. 39, among others. For example, negative pressure within the cavity 230 can exceed a threshold pressure when one or more of the suction openings 3905 becomes occluded. When the threshold negative pressure within the cavity 230 is removed, the suction element 3800 can move from the retracted state to the extended state. Movement of the suction element 3800 from the extended state to the retracted state can act to jostle, loosen, disperse, break apart, or otherwise move any mucus, secretions, debris, or other material that may build up at or proximate to the suction opening 3505. By moving to jostle, loosen, disperse, break apart, or otherwise move any mucus, secretions, debris, or other material near the suction opening 3505, a likelihood that the mucus, secretions, debris, or other material near the suction opening 3505 will at least partially occlude the suction opening 3505 can be reduced, thereby preserving or increasing the efficacy of the oral medical device 100.

[0213] FIG. 40, among others, depicts the second portion 110 of the oral medical device 100 having a suction element 4000 (e.g., a suction portion, a suction paddle). The suction element 4000 includes at least one suction opening 4005 (e.g., an aperture 4005, a second opening 4005) fluidly coupled with the cavity 230 of the second portion 110. The cavity 230 can be positioned within the suction element 4000. The suction opening 4005 can be an opening through which irrigation fluid or other material (e.g., mucus, secretions, debris, or other material) can be drawn into the cavity 230 within the suction element 4000. For example, the suction element 4000 can be coupled with the second conduit 130, which can further be under vacuum pressure or negative pressure to draw the irrigation fluid and other material form794931 -5214-5527.2Atty. Dkt: 139168-0149; SWF-008PCT the oral cavity of the patient and into the suction cavity 230 of the suction element 4000 to remove said irrigation fluid and other material from the oral cavity of the patient. The suction opening 4005 can be disposed on a distal end of the suction element 4000, where the distal end of the suction element 4000 can be an end or tip of the suction element 4000 that is positioned farthest within a patient’s oral cavity during operation of the oral medical device 100. The second conduit 130 can be coupled with a proximal end of the suction element 4000, for example. In other examples, the suction element 4000 can include the suction opening 4005 positioned elsewhere, such as on an inner surface of the suction element 4000, on an outer surface of the suction element 4000, or some other surface of the suction element 4000. In yet other embodiments, the suction element 4000 can include multiple suction openings 4005 positioned in various positions on the suction element 4000.

[0214] The suction element 300 can include multiple projections 4010 (e.g., bumps, stipples, protrusions, or other projections) that can extend outwardly from the suction element 4000. The projections 4005 can contact a tongue of a patient during operation of the oral medical device 100. For example, the projections 4005 can contact the tongue of the patient to keep the tongue of the patient substantially away from the suction opening 4005 of the suction element 4000. By keeping the tongue of the patient away from the suction opening 4005, the projections 4010 can substantially prevent or reduce the incidence of the suction opening 4005 becoming at least partially occluded by the tongue of the patient. For example, if the tongue of the patient partially occludes the suction opening 4005, the efficacy of the suction opening 4005 in removing irrigation fluid or other material from the oral cavity of the patient is reduced. Because the projections 4010 extend from the inner surface 310 of the suction element 300 and at least partially toward the first portion 105 (e.g., toward the tongue of the patient), the projections 4010 are positioned to contact the tongue of the patient before the tongue of the patient can occlude the suction opening 4005. The projections 4010 stands proud relative to the suction element 4000 to create or enforce a space or distance between the tongue of the patient and the suction opening 4005 of the suction element 4000, thereby substantially preventing occlusion of the suction opening 4005 by the tongue of the patient.

[0215] FIG. 41, among others, depicts a cross-section of the second portion 110 of the oral medical device 100 having a suction element 4100 (e.g., a suction portion, a suction paddle). The suction element 4100 includes at least one suction opening 4110 (e.g., an aperture 4110, a second opening 4110) fluidly coupled with the cavity 230 of the second portion 110. The804931 -5214-5527.2Atty. Dkt: 139168-0149; SWF-008PCT cavity 230 can be positioned within the suction element 4100. The suction opening 4110 can be an opening through which irrigation fluid or other material (e.g., mucus, secretions, debris, or other material) can be drawn into the cavity 230 within the suction element 4000. For example, the suction element 4100 can be coupled with the second conduit 130, which can further be under vacuum pressure or negative pressure to draw the irrigation fluid and other material form the oral cavity of the patient and into the suction cavity 230 of the suction element 4100 to remove said irrigation fluid and other material from the oral cavity of the patient. The suction opening 4110 can be disposed on a distal end of the suction element 4100, where the distal end of the suction element 4100 can be an end or tip of the suction element 4100 that is positioned farthest within a patient’s oral cavity during operation of the oral medical device 100. The second conduit 130 can be coupled with a proximal end of the suction element 4100, for example. In other examples, the suction element 4100 can include the suction opening 4110 positioned elsewhere, such as on an inner surface of the suction element 4100, on an outer surface of the suction element 4100, or some other surface of the suction element 4100. In yet other embodiments, the suction element 4100 can include multiple suction openings 4110 positioned in various positions on the suction element 4100.

[0216] The suction element 4100 can include a projection 4105 that extends through an opening 4115 of the suction element 4100 and stands proud relative to an outer surface of the suction element 4100. The projection 4105 can be coupled with the suction element 4100 at a base of the opening 4115. For example, the physical connection between the projection 4105 and an inner wall of the opening 4115 can be or include multiple discontinuous segments, such as radially oriented segments or some other discontinuous segments. The segments coupling the projection 4105 with the inner wall of the opening 4115 can create the suction opening 4110 that can be positioned between two adjacent segments, for example. In this way, the suction opening 4110 is positioned at a base of the projection 4105 and at a base of the opening 4115. With the projection 4105 extending through the opening 4115, an accessible area of the opening 4115 can have an annular shape or some other shape defined by a space between an outer wall of the projection 4105 and the inner wall of the opening 4115. The annular shape of the opening 4115, particularly with the projection 4105 standing proud relative to an outer surface of the suction element 4100, can create an opening that is difficult to occlude by a single object (e.g., a tongue, a mass of mucus, debris, or some other object). For example, by virtue of its shape and the protrusion of the projection 4105 outward from the opening, it is unlikely that any object will fully occlude the opening 4115. Because the opening 4115 is not814931 -5214-5527.2Atty. Dkt: 139168-0149; SWF-008PCT easily occluded, so too is the suction opening 4110 that is positioned within the opening 4115. Accordingly, the suction element 4100 can substantially prevent or reduce an incidence of an occlusion substantially affecting the performance of efficacy of the second portion 110.

[0217] FIG. 42 depicts at least a portion of an oral medical device 4200. The oral medical device 4200 can facilitate the irrigation and suctioning of an oral cavity of a patient. For example, the oral medical device 4200 can be inserted into an oral cavity (e.g., a mouth) of a patient and can be configured to provide an irrigation fluid (e.g., water, saline solution, or some other irrigation fluid) into the oral cavity of the patient to irrigate the oral cavity of the patient. Irrigation can include providing fluid to the oral cavity to clean (e.g., cleanse, disinfect, wash, rinse, or otherwise clean) or provide some other therapeutic treatment to the oral cavity. For example, the oral medical device 4200 can provide the irrigation fluid to the oral cavity, where the irrigation fluid can wash away pathogens, bacteria, particulate matter, or other undesirable substances that may have accumulated within the oral cavity of the patient. The oral medical device 4200 can be inserted into the oral cavity of the patient and can be configured to suction (e.g., remove, evacuate via negative pressure, or otherwise draw out) the irrigation fluid (e.g., the irrigation fluid that is first provided into the oral cavity by the oral medical device 4200), pathogens, bacteria, particulate matter, mucus, secretions, debris, or other material from the oral cavity of the patient. For example, the oral medical device 4200 can remove the irrigation fluid from the oral cavity after the irrigation fluid has first been provided to the oral cavity to clean the oral cavity as well as mucus, secretions, and other debris that may be present within the oral cavity of the patient.

[0218] The portion of the oral medical device 4200 depicted in FIG. 42 can be used for suction purposes, to remove fluid from an oral cavity, and can be coupled with irrigation components (not shown). The portion of the oral medical device depicted in FIG. 42 can also be used to provide irrigation to the oral cavity to provide fluid out from the device 4200, for example into an oral cavity.

[0219] The oral medical device 4200 can be used in conjunction with (e.g., simultaneously with) other medical devices, such as an endotracheal tube or some other medical device, as noted above. The oral medical device 4200 can be used independent of any other medical device, in other examples. As mentioned above, the patient’s oral cavity can be in need of irrigation or cleaning (e.g., cleansing with solution, disinfection, scrubbing, removal of microbes, bacteria or particulate matter, or some other type of cleaning) as the patient remains824931 -5214-5527.2Atty. Dkt: 139168-0149; SWF-008PCT intubated (e.g., via an endotracheal tube). Moreover, the presence of an endotracheal tube or another medical device within the oral cavity of the patient can inhibit or obstruct access to the oral cavity and substantially prevent the irrigation or cleaning of the oral cavity by conventional means (e.g., brushing with tooth brush, rinsing with water, or some other means.) Further, if the patient is ventilated, it can be undesirable to irrigate or clean the oral cavity of the patient by conventional means because to do so may risk introducing fluid into the patient’s lungs.

[0220] The oral medical device 4200 can include at least one first conduit 4205 having at least one first aperture 4210. The first conduit can convey fluid to or from the first aperture 4210. For example, fluid can be suctioned from an oral cavity into the first conduit 4205 via the first aperture 4210. The first conduit 4205 can include at least one first portion 4215 and at least one second portion 4220, which can be separated from one another be at least one additional conduit. For example, at least one second conduit 4225 or third conduit 4230 can branch off of the first conduit 4205. The second conduit 4225 or third conduit 4230 can define the boundary between the first portion 4215 and second portion 4220 of the first conduit 4205.

[0221] Fluid can flow through the first conduit 4205 through the aperture 4210 and to or beyond a distal end 4235 of the first conduit 4205. Fluid from the second conduit 4225 can flow through the second conduit 4225 between the second aperture 4240 and the distal end 4235 of the first conduit 4205. Fluid from the third conduit 4230 can flow through the second conduit 4225 between the second aperture 4245 and the distal end 4235 of the first conduit 4205. The first conduit 4205, second conduit 4225, and third conduit 4230 can have the same or similar (e.g., within ± 10%) dimensioned inner diameter, or can be differently sized. For example, the second conduit 4225 and third conduit 4230 can each have an inner diameter that is less than the inner diameter of the first conduit 4215. The second conduit 4225 and third conduit 4230 can also each have an inner diameter that is greater than the inner diameter of the first conduit 4215, and all three conduits 4205, 4225, 4230 can have different inner diameters than each other. The three conduits 4205, 4225, 4230 can be made of the same or different material, and can be the same or different lengths. For example, from the branch point that divides the first portion 4215 from the second portion 4220, the second conduit 4225 and the third conduit 4230 can have the same lengths as one another, or different lengths. The first portion 4220 of the first conduit 4205 can be longer than both the second conduit 4225 and the third conduit 4230.834931 -5214-5527.2Atty. Dkt: 139168-0149; SWF-008PCT

[0222] The apertures 4210, 4240, and 4245 can also be disposed at a tip region of the respective conduits 4205, 4225, and 4230, or can be disposed elsewhere on the walls of the conduits. There can be one or more apertures 4210, 4240, and 4245 disposed on each respective conduit 4205, 4225, 4230 in for example a symmetrical or asymmetrical configuration. The apertures can provide openings to suction fluid into the conduits, or to dispose fluid out from the conduits. There can be for example two or three apertures on each conduit symmetrically or asymmetrically spaced around the outer diameter of the conduit(s). The conduits 4205, 4225, 4230, can be circular or elliptical in cross section, among other regular and irregular shapes. The conduits 4205, 4225, 4230 can be integral parts of the oral medical device 4200, for example molded from the same materials, or they can be separate components that are fluidly coupled together for example by inserting the second conduit 4225 or third conduit 4230 into openings of the first conduit 4205 that are then sealed to prevent the leakage of fluid or loss of suctioning pressure.

[0223] The material of the oral medical device 4200 can be rigid, flexible, or of any consistency. There can be any number of conduits (e.g., more than three) and any conduit can branch off any other conduit. For example, the second (or any other) conduit 4225 can itself include two additional branch conduits that branch off of the second conduit 4225.

The second conduit 130 can be fluidly coupled with a second cavity 230 of the second portion 110, and can receive fluid from the second portion 110. The second conduit 230 can be fluidly coupled to a pump or other mechanism capable of applying a vacuum or negative pressure to the second conduit 230 to draw fluid (e.g., previously-dispensed irrigation fluid and any associated particulate matter or debris) from the oral cavity of the patient to via the second portion 110. For example, the second portion 110 can be or include the suction element 300, the suction element 500, the suction element 600, the suction element 700, the suction element 800, the suction element 900, the suction element 1100, the suction element 1200, the suction element 1300, the suction element 1400, the suction element 1500, the suction element 1600, the suction element 1700, the suction element 2000, the suction element 2100, the suction element 2200, the suction element 2400, the suction element 2500, the suction element 2900, the suction element 3000, suction element 3100, the suction element 3300, the suction element 3500, the suction element 3800, the suction element 4000, the suction element 4100 or some other suction element described herein or otherwise. The second portion 110 can be structured to remove fluid (e.g., previously-dispensed irrigation fluid and any associated particulate matter944931 -5214-5527.2Atty. Dkt: 139168-0149; SWF-008PCT or debris) from the oral cavity of the patient. The second portion 110 can include the suction element including one or more feature to substantially prevent or reduce the incidence of occlusion of an opening formed in the second portion 110 so that fluid can flow into the cavity 230 of the second portion 110 without interruption due to occlusion, for example. Collectively, the first portion 105 and the second portion 110 can comprise the oral medical device 100.

[0248] The method 5100 can include providing a pressure modulator at ACT 5115. For example, the actuator can be coupled to the second portion 110. The pressure modulator can be or include the actuator 2425, which can include a tube 2800 as depicted in FIG. 28, for example. The pressure modulator can be or include the actuator 2700 depicted in FIG. 27. The pressure modulator can be fluidly coupled with the cavity 230 of the second portion 110 and can be configured to receive a user input. The pressure modulator can be further configured to alter a pressure within the cavity 230 in response to a user input. For example, a user input can cause a vacuum pressure to increase within the cavity 230 (e.g., a negative pressure spike).

[0249] FIG. 52 depicts a method 5200. The method 5200 can be a method of operating an oral medical device such as the oral medical device 4200. The method 5200 can include ACTS 5205-5220, among others. At ACT 5205, the method 5200 can include coupling a first conduit with a second conduit. The first conduit can be any one of the first conduit 4205, the second conduit 4225, or the third conduit 4230. The second conduit can be another of the first conduit 4205, the second conduit 4225, or the third conduit 4230. The first conduit and the second conduit can be fluidly coupled together and can be or include separate branches or portions of a common conduit network for example. At ACT 5210, the method 5200 can include receiving a first fluid. The first fluid can be an irrigation fluid received by the first conduit via a first aperture of the first conduit (e.g., the aperture 4210). For example, the first fluid can be fluid located within a patient’s oral cavity, and the first conduit can be under vacuum pressure to suck or remove the fluid from the oral cavity. At ACT 5215, the method 5200 can include receiving a second fluid. The second fluid can be an irrigation fluid received by the second conduit via a second aperture of the second conduit (e.g., the aperture 4245). For example, the second fluid can be fluid located within a patient’s oral cavity, and the second conduit can be under vacuum pressure to suck or remove the fluid from the oral cavity. At ACT 5220, the method 5200 can include providing the second fluid. For example, ACT 5220 can include providing the second fluid to the first conduit via the second conduit. In such examples, the second conduit is fluidly coupled with the first conduit. For example, the first conduit and the954931 -5214-5527.2Atty. Dkt: 139168-0149; SWF-008PCT second conduit can be fluidly coupled, and the second conduit can flow into the first conduit.

[0250] FIG. 53 depicts a method 5300. The method 5300 can be a method of operating an oral medical device such as the oral medical device 4200. The method 5300 can include ACTS 5305-5320, among others. At ACT 5305, the method 5300 can include coupling a first conduit with a second conduit. The first conduit can be any one of the first conduit 4205, the second conduit 4225, or the third conduit 4230. The second conduit can be another of the first conduit 4205, the second conduit 4225, or the third conduit 4230. The first conduit and the second conduit can be fluidly coupled together and can be or include separate branches or portions of a common conduit network for example. At ACT 5310, the method 5300 can include providing a first fluid. The first fluid can be an irrigation fluid provided by the first conduit to the oral cavity via a first aperture of the first conduit (e.g., the aperture 4210). For example, the first fluid can be fluid provided to a patient’s oral cavity. At ACT 5315, the method 5300 can include providing a second fluid. The second fluid can be an irrigation fluid provided by the second conduit to the oral cavity via a second aperture of the second conduit (e.g., the aperture 4245). For example, the second fluid can be provided to a patient’s oral cavity. At ACT 5320, the method 5200 can include receiving the second fluid. For example, ACT 5320 can include receiving the second fluid provided by the second conduit at ACT 5315 via the first conduit. For example, subsequent to providing fluid at ACT 5310, the first conduit can be under vacuum pressure to suck or remove the fluid from the oral cavity.
