[0001] The utility model relates to the technical field of medical supplies, in particular to a detachable oral and nasal mask. Background Art

[0002] In order to reduce the discomfort and fear of patients during painless gastrointestinal endoscopy and some bronchoscopy, intravenous anesthesia is often used while maintaining spontaneous breathing. During the examination, the examiner needs to occupy the oral airway and use an endoscope to enter the body through the patient's mouth. During the anesthesia, due to the respiratory depressant effect of intravenous anesthetics or upper airway obstruction after sedation, patients may be more likely to have difficulty breathing and decrease blood oxygen saturation, especially those who are obese with sleep apnea syndrome or small jaws. In severe cases, the operation needs to be stopped. However, when the examination reaches an important step, the operation is often not stopped immediately, and the oxygen supply efficiency needs to be improved while the examination is being performed. This poses a huge challenge to doctors and seriously threatens patient safety. Anesthesia masks commonly used in clinical practice, such as the Chinese patent with patent application number 202021538752.0, discloses a mask for painless gastroenteroscopy, including an oxygen mask, a bite fixedly arranged in the oxygen mask, and an operating port corresponding to the bite.

[0030] The following will be combined with the drawings in the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work belong to the protection scope of the utility model.

[0031] like Figures 1 to 6 As shown, the embodiment of the utility model provides a detachable oral-nasal mask 100, including a nasal mask 100 and an oral mask 200 detachably connected to the nasal mask 100. The examiner can choose to use the nasal mask 100 alone according to actual use needs, or can choose to use the nasal mask 100 and the oral mask 200 together, which is flexible and convenient; wherein the detachable connection between the nasal mask 100 and the oral mask 200 can be realized by snapping or gluing, but is not limited thereto. For example, the snapping method can be achieved by providing a slot on the nasal mask 100, and providing a snap-in protrusion on the oral mask 200 that snaps with the slot; the gluing method can be achieved by Velcro, non-stick adhesive, etc.

[0032] The oxygen tube interface 110 provided on the nasal mask 100 is used to connect with the oxygen tube of the wall humidifier bottle for oxygen supply therapy; Figure 4 The oxygen tube interface 110, the nasopharyngeal ventilation tube interface 170, the anesthesia machine threaded tube interface 190, and the carbon dioxide collection port 180 are not shown, but it should not be understood that the above-mentioned unshown parts cannot exist in this embodiment or other embodiments.

[0033] The nasal mask 100 is also formed with a sealing plate 140 on one side close to the oral mask 200, and the sealing plate 140 separates the internal spaces of the nasal mask 100 and the oral mask 200 from each other; the sealing plate 140 is also provided with a vent 130, and after the nasal mask 100 and the oral mask 200 are connected, the vent 130 is located inside the space enclosed by the nasal mask 100 and the oral mask 200, so as to realize the communication between the internal space of the nasal mask 100 and the internal space of the oral mask 200, so that the oxygen in the nasal mask 100 can enter the oral mask 200 through the vent 130. The vent 130 is also provided with a seal for opening or closing the vent 130. For example, when the nasal mask 100 and the oral mask 200 are used together, the seal opens the vent 130, and when the nasal mask 100 is used alone, the seal closes the vent 130.

[0034] The mouth mask 200 is provided with an endoscope port 220, and an opening 210 is provided at the edge of the mouth mask 200. The opening 210 extends from the edge of the mouth mask 200 to the endoscope port 220 and is connected to the endoscope port 220. The width of the opening 210 is sufficient for the insertion tube of the endoscope to pass through. The width of the opening 210 is the size of the opening 210 perpendicular to its extension direction. During the examination, if the patient's blood oxygen saturation decreases, there is no need to withdraw the mirror. The insertion tube of the endoscope can enter the endoscope port 220 through the opening 210 on the mouth mask 200, and then the mouth mask 200 is connected to the nasal mask 100, and the wearing is completed quickly to perform non-invasive ventilation of the mouth and nose to improve the oxygen supply effect; it should be noted that when the nasal mask 100 is used alone, the vent 130 needs to be closed to prevent oxygen from being directly discharged to the outside of the nasal mask 100 through the vent 130 during use, resulting in an inability to effectively supply oxygen to the patient.

[0035] Specifically, in order to realize the wearing of the detachable oral and nasal mask on the patient's head, straps can be fixedly provided on both sides of the nasal mask 100 and the oral mask 200. In this embodiment, a first strap 160 is provided on the nasal mask 100, and a second strap 240 is provided on the oral mask 200. The lengths of the first strap 160 and the second strap 240 can be adjusted, and both are elastic straps. When the patient uses them, they can be adjusted according to the patient's specific situation, and the elastic material makes them more comfortable to wear.

[0036] Further, such as Figure 1 and Figure 6 As shown, the sealing member is preferably set as a first sealing cover covering the vent 130, which is convenient and quick to operate, greatly improving the life protection of the patient, and the sealing cover is used for sealing, so that the overall air tightness of the nasal mask 100 is stronger and the oxygen supply efficiency is high. In addition, the first sealing cover can be covered on the vent 130 by means of snap-fitting, gluing or threaded connection, and the sealing member can also realize the present invention if it adopts a structure such as a sliding door sheet or an indentation sheet, but the matching method of the first sealing cover and the vent 130 is not limited to this.

[0037] Further, such as Figures 1 to 5 As shown, by providing mutually cooperating card slots and card blocks at the connection of the nasal mask 100 and the oral mask 200 for card fixing, the card fixing method can realize the rapid installation and connection of the oral and nasal mask. If the patient's blood oxygen saturation decreases during the examination, it may even threaten the patient's life. Therefore, improving the connection efficiency of the oral and nasal mask and quickly improving the oxygen supply efficiency can effectively improve the life protection of the patient.

[0038] Further, such as Figures 1 to 5As shown, the nasal mask 100 and the oral mask 200 realize the snap connection of the oral and nasal mask through the mutually cooperating snap slots 150 and snap protrusions 250. Specifically, the nasal mask 100 is provided with a snap slot 150, and the oral mask 200 is provided with a snap protrusion 250 that cooperates with the snap slot 150; or the nasal mask 100 is provided with a snap protrusion 250, and the oral mask 200 is provided with a snap slot 150 that cooperates with the snap protrusion 250. However, it should be noted that the snap slot 150 or the snap protrusion 250 provided on the nasal mask 100 is provided on the upper edge of one side close to the oral mask 200.

[0039] Specifically, in this embodiment, a slot 150 is preferably provided on the upper edge of one side of the nasal mask 100 close to the oral mask 200, and a snap-in protrusion 250 is provided at a position corresponding to the slot 150 on the side of the oral mask 200 close to the nasal mask 100, and the snap-in protrusion 250 is snapped into the slot 150, and cooperates with each other to realize the quick connection between the oral mask 200 and the nasal mask 100. At this time, the slot 150 is an arc-shaped slot provided along the upper edge of the nasal mask 100, and the snap-in protrusion 250 is an arc-shaped snap-in protrusion provided on the inner wall of the oral mask 200, and the snap-in connection between the two can effectively increase the airtightness of the connection, but the slot 150 is provided as a plurality of snap-in slots 150 provided at intervals along the upper edge of the nasal mask 100, which can also realize the utility model.

[0040] Further, such as Figure 1 and Figure 2 As shown, a slot 150 is provided on one side of the nasal mask 100 close to the oral mask 200, a snap-on protrusion 250 is provided on the oral mask 200, and the opening 210 provided on the oral mask 200 is provided on the side of the oral mask 200 where the snap-on protrusion 250 is provided. At this time, a support portion 151 may also be provided in the slot 150, and the support portion 151 may be a structure such as a support column, a reinforcing rib or a support block, so as to avoid the width of the slot 150 changing due to the nasal mask 100 being subjected to force, which affects the insertion of the snap-on protrusion 250 into the slot 150. Among them, the support portion 151 may be a separately manufactured component, and then snap-fitted and fixed inside the slot 250, or may be integrally formed with the nasal mask 100. In addition, a yielding portion should be provided at a position corresponding to the support portion 151 on the snap-on protrusion 250, and its position corresponds to the position of the support portion, so that the snap-on protrusion 250 can be snap-fitted inside the slot 150.

[0041] Furthermore, in this embodiment, the end of the clamping protrusion 250 facing the clamping slot 150 is set to be tapered, and further rounded, so that the clamping protrusion 250 is easier to insert into the clamping slot 150, and the connection speed of the oral mask and the nasal mask is improved. It can be understood that the end of the clamping protrusion facing the clamping slot refers to the end of the clamping protrusion that first enters the clamping slot when the clamping protrusion is matched with the clamping slot.

[0042] Further, such as Figure 1 and Figure 3 As shown, a shielding portion 260 is provided on the oral mask 200, and the shielding portion 260 completely covers the opening 210 to prevent oxygen from flowing out of the mask through the opening 210 during the combined use of the nasal mask 100 and the oral mask 200, so as to improve the oxygen supply efficiency. Specifically, the shielding portion 260 can be a shielding sheet connected to the top of the opening 210 by a detachable manner such as gluing or snapping, and can achieve a shielding and sealing effect on the opening 210. For example, the shielding sheet can be a rubber sheet, and one side of the rubber sheet can be flipped and set on one side of the opening, and the opening can be opened or covered by flipping the rubber sheet.

[0043] Further, such as Figure 1 to Figure 2 As shown, the nasal mask 100 is also provided with a nasopharyngeal ventilation tube interface 170, an anesthesia machine threaded tube interface 190, and a carbon dioxide collection port 180; the nasopharyngeal ventilation tube interface 170 is used to install a one-way ventilation valve, and the nasopharyngeal ventilation tube is inserted into the nasopharyngeal ventilation tube interface 170 to alleviate the patient's ventilation difficulties such as tongue prolapse; the anesthesia machine threaded tube interface 190 is used to connect to the anesthesia machine threaded tube to implement anesthesia; the carbon dioxide collection port 180 is used to connect to the sampling tube of the monitor when carbon dioxide collection is required, monitor the patient's breathing, and judge whether there is carbon dioxide accumulation through the collected values. If there is accumulation, corresponding treatment measures should be taken, and the ventilation port 130 needs to be closed when carbon dioxide is collected.

[0044] Further, such as Figure 1 to Figure 2 As shown, the anesthesia machine threaded pipe interface 190, the nasopharyngeal ventilation tube interface 170, the oxygen tube interface 110, and the carbon dioxide collection port 180 are all provided with a second sealing cover. When not in use, the second sealing cover is covered and each pipe interface is closed, which does not affect the normal use of the oral and nasal mask 100.

[0045] Further, such as Figures 1 to 6As shown, a first airbag 120 is further provided at the contact point between the nasal mask 100 and the face, and a second airbag 230 is further provided at the contact point between the oral mask 200 and the face. When the nasal mask 100 and the oral mask 200 are worn, the first airbag 120 and the second airbag 230 are in contact with the face, which can effectively reduce the pressure of the mask on the patient's face during wearing, improve wearing comfort, and avoid facial discomfort or even damage caused by long-term wearing; both the first airbag 120 and the second airbag 230 are provided with an inflation port for inflation, specifically, the first airbag 120 is provided with a first inflation port 121, and the second airbag 230 is provided with a second inflation port 231. When the user wears the detachable oral and nasal mask, the nasal mask 100 contacts the face at the edge of the nasal mask 100, and correspondingly, the oral mask 200 contacts the face at the edge of the oral mask 200, so that the first airbags are distributed along the edge of the nasal mask 100 that contacts the face, and the second airbags 230 are distributed along the edge of the oral mask that contacts the face. It can be understood that the edge of the nasal mask 100 that contacts the face includes one side edge of the diaphragm.

[0046] When in use, the examiner can choose to use the nasal mask 100 alone or combine the nasal mask 100 and the oral mask 200 according to the examination items and the actual situation of the patient. When the nasal mask 100 is used alone, the oxygen supply device is connected to the oxygen tube interface 110 on the nasal mask 100 and the wearing is completed. At this time, the patient's mouth is not blocked, which is convenient for the examiner to perform the examination operation. If the patient's blood oxygen saturation decreases during the examination, the examiner inserts the endoscope into the endoscope port 220 through the opening 210 on the oral mask 200, connects the shielding sheet, removes the first sealing cover at the same time, opens the vent 130, connects the oral mask 200 and the nasal mask 100, quickly completes the wearing of the oral mask 200, realizes non-invasive ventilation of the mouth and nose, improves the oxygen supply efficiency, avoids the operation of withdrawing the mirror, and is flexible and convenient to use. If the nasal mask 100 oxygen supply treatment is still needed after the examination is completed, it is only necessary to remove the oral mask 200 and close the vent, which is flexible and convenient to use.

[0047] The utility model is further described above with the help of specific embodiments, but it should be understood that the specific description here should not be construed as limiting the essence and scope of the utility model. Various modifications made to the above embodiments by ordinary technicians in this field after reading this specification are all within the scope of protection of the utility model.
