Description

Technical Field

[0001] Invention Field This invention relates to the field of fittings for gas delivery hoses. Prior Technology

[0002] Background of the Invention A nasal cannula is a device used to deliver supplemental oxygen, other gases, or airflow to patients or individuals requiring treatment or assisted breathing. Typically, the cannula comprises a plastic tube and a set of two needles placed in the nostril. Oxygen or other gases can flow through these needles.

[0003] Nasal cannulas can be connected to oxygen cylinders, portable oxygen concentrators, wall mounts in hospitals via flow meters, or other gas sources. The cannulas can deliver oxygen to patients at rates that depend in part on their size. For example, nasal cannulas for infants or newborns can deliver less oxygen and use smaller needles compared to those for adults. The cannulas can be used to supply oxygenated air, humidified air, or other gas mixtures. Summary of the Invention

[0004] Invention Summary Therefore, an object of the present invention is to provide a connector and / or a connector for a gas delivery hose that will at least partially solve the aforementioned problems or at least provide the public with a useful option.

[0005] References to patent specifications, other external documents, or other sources of information have been made in this specification, generally to provide text for discussing the features of the invention. Unless otherwise expressly stated, references to such external documents should not be construed as an admission that such documents or sources of information are known art or part of the general common knowledge in any jurisdiction.

[0006] Other aspects and advantages of the invention will become clear from the following description, given only by way of example.

[0007] In some cases, nasal cannulas are used to deliver humidified airflow or oxygen therapy. To monitor the airflow received by the patient, a sensor probe can be used. However, the farther the probe is from the needle supplying air to the nostrils, the greater the potential difference between the sampled air and the air inhaled by the patient. Therefore, placing the sensor probe closer to the airflow in a catheter connector can improve the accuracy of the measurements.

[0008] Because nasal cannulas or other breathing devices are connected to patients for extended periods, they can cause discomfort or otherwise begin to perform poorly. For example, as patients move around in their hospital beds, the tubing may become tangled or twisted, leading to discomfort or restricting airflow within the tube. Therefore, a design that facilitates adjustment of the nasal cannula can provide greater patient comfort or improve performance.

[0009] Sometimes, it may be necessary to remove or replace a nasal cannula or airflow source. If removing the nasal cannula from the airflow source is difficult or time-consuming, it can cause serious discomfort to the patient. Furthermore, in emergency situations, slow or difficult connection mechanisms can potentially endanger the patient's health. Therefore, a catheter connector that provides a "quick connection" or "quick release" feature offers greater comfort and / or safety, facilitating attachment and removal of the nasal cannula from the airflow source, and contributing to component interchangeability.

[0010] To address the problems discussed above, several aspects of this disclosure include a connector or connector assembly for attaching a nasal cannula to a gas delivery tubing. In one embodiment, the connector element includes a sensor port for a sensor probe. The sensor port is positioned near one end of the nasal cannula, facing the patient. In one embodiment, the connector is configured to allow the sensor to be placed closer to the patient's nostril than previous connector parts have permitted.

[0011] Several aspects of the invention also include a self-aligning connector element configured to automatically align a plurality of locking protrusions on a first component with a plurality of locking recesses on a second component, wherein insertion of the second component into the first component causes the second component to rotate relative to the first component, thereby aligning the locking protrusions with the associated locking recesses. In one embodiment, the connector is configured to advantageously allow rotation of the nasal cannula relative to the gas delivery tubing. By allowing rotation, the connector enables a patient or healthcare provider to unwind or otherwise straighten the tubing or cannula, thereby improving patient comfort.

[0012] As used in this specification, the term "comprising" means "consisting of at least in part...". When interpreting each statement in this specification containing the term "comprising", features other than the one or more features following that term may also exist. For example, related terms such as "includes" and "comprises" will be interpreted in the same manner.

[0013] The present invention can also be broadly defined as any part, element, and feature individually or collectively referred to or specified in the description of this application, as well as any or all combinations of any two or more of the said parts, elements, or features, and when a specific integer having a known equivalent in the field to which the present invention relates is referred to herein, such known equivalents are considered to be incorporated herein as if individually listed.

[0014] The present invention is based on the foregoing content, and various structures are also envisioned, of which only examples are given below. Simple Explanation of the Diagram

[0033] Detailed Description of Preferred Embodiments Figures 1A and 1B show a perspective view and a side view, respectively, of a gas delivery conduit 100, which includes an embodiment of a connector 105 for attaching a first conduit 110 from a nasal cannula, mask, tubing, or other breathing device for a patient to a second conduit 115 from a ventilator, humidifier, breathing circuit, or other airflow device for delivering gas to a patient. This connector allows components of the gas delivery conduit 100 to be connected or disconnected from each other, thereby facilitating the disconnection and reconnection of the breathing device and airflow device with minimal potential disruption to the patient or the gas delivery system.

[0034] For example, a patient may receive humidified, oxygenated, and / or pressurized gas via a nasal cannula 110 connected to a gas delivery line 115, which in turn connects to a humidifier or ventilator. For ease of explanation, the following disclosure relates to several embodiments of a connector for connecting a nasal cannula to a gas delivery line (e.g., for providing oxygen), but mention of such embodiments is not intended to limit this disclosure, and other embodiments are possible. For example, in other embodiments, alternative patient interfaces such as nasal masks or full-face masks may be used to supply gas to the patient, or alternative gas flow sources may be used to supply gas.

[0035] In the illustrated embodiment, connector 105 includes a terminal catheter connector 120 for receiving a nasal cannula 110, a source catheter connector 125 for receiving a gas delivery conduit 115, and a connection adapter 140 for connecting the catheter connectors. The source catheter connector 125 includes an optional sensor port 130 for receiving a sensor probe 135. In the illustrated embodiment, the connection adapter 140 releasably connects the terminal catheter connector 120 to the source catheter connector 125. The gas delivery conduit 115 is configured to connect to the source catheter connector 125, and the nasal cannula 110 is configured to connect to the terminal catheter connector 120, thereby forming a gas conduit 100 for supplying oxygen or other gases to a patient. Typically, oxygen flows from the gas delivery conduit 115 to the nasal cannula 110. For ease of explanation, the orifice of the gas conduit components adjacent to the gas delivery conduit 115 is referred to as the source orifice, and the orifice adjacent to the nasal cannula 110 is referred to as the terminal orifice.

[0036] In the illustrated embodiment, a source port 145 of the source conduit connector 125 is connected to the gas delivery conduit 115, for example, by fitting over and / or around the gas delivery conduit 115 to form a seal. The source conduit connector 125 may be releasably or permanently attached to the gas delivery conduit 115. In one embodiment, the terminal port 150 of the source conduit connector 125 includes a plurality of locking tabs 151 and / or alignment tabs 152 for receiving the connection adapter 140. In one embodiment, the locking tabs are configured to lock by a plurality of locking recesses 154 formed on a plurality of fingers 153 of the connection adapter 140, thereby forming a releasable seal. In one embodiment, the alignment tabs 152 are configured to rotate the connection adapter 140 within the terminal port 150 if the locking tabs are not aligned with the locking recesses when the locking recesses are inserted into the terminal port 150. The alignment tabs rotate the connection adapter 140 until the locking tabs align with the locking recesses. In one embodiment, the recesses 154 extend through the holes in the finger-shaped member 153 and are configured to serve the same function as the recesses 154.

[0037] In one embodiment, the locking tabs are configured to engage with the locking recesses 154, producing a click to provide affirmative feedback that a complete connection has been established. In one embodiment, such a click can be produced when the fingers 153 are biased as they pass the locking tabs, and subsequently when the locking recesses 154 engage with the locking tabs. An audible click can also be produced in other ways, such as when other components engage with each other.

[0038] In the illustrated embodiment, a source port 155 of the terminal conduit connector is configured to receive the connector adapter 140 to form a rotatable connection. In one embodiment, a plurality of ridges formed within the terminal conduit connector are adapted to lock with a channel 160 formed on the circumference of the connector adapter 140. By allowing the ridges to rotate along the channel 160, the terminal conduit connector 120 and the connector adapter 140 are rotatable relative to each other. In one embodiment, a plurality of raised edges or collars along the terminal port and source port of the connector adapter 140 prevent or inhibit disengagement of the terminal conduit connector 120 from the connector adapter 140.

[0039] The terminal catheter connector 120 may include a terminal aperture configured to receive a nasal cannula 110. The terminal aperture 165 may include two openings for receiving a dual-catheter cannula. Each catheter may be connected to a pin for insertion into a patient's nostril. The nasal cannula 110 may be releasably or permanently attached to the terminal catheter connector 120.

[0040] Figure 1B shows a side view of connector 105. Source catheter connector 125 is connected to terminal catheter connector 120. Sensor probe 135 is connected to connector 105 through sensor port 130. Axis 167 shows a cross-section, which is taken in Figure 6.

[0041] Figure 1C shows a perspective view of another connector embodiment, which includes a source catheter connector 125, a terminal catheter connector 120, and a connection adapter 140 (hidden in this view). This embodiment shares many of the structures and features discussed above with respect to Figure 1A, such as the sensor port 130.

[0042] Figure 2A shows a perspective view of the side of the terminal orifice 150 of the source conduit connector 125 of Figure 1A. In the illustrated embodiment, the source conduit connector 125 includes a generally cylindrical conduit having a terminal orifice 150 and a source orifice 145 (Figure 1A). The source conduit connector 125 may also include an optional sensor port 130 for receiving a sensor probe 135. In Figure 2A, the sensor port 130 includes a generally cylindrical conduit extending perpendicularly from the source conduit connector 125. In some embodiments, the conduit is perpendicular to the body of the conduit connector 125. In some embodiments, the conduit is generally vertical but may form an angle of a few degrees with respect to the vertical (e.g., less than 5 degrees, 10 degrees, or 15 degrees). In some embodiments, the angle formed by the conduit exceeds 15 degrees. One or more finger grooves 202 may be formed on the outer surface of the source conduit connector 125 to provide the user with additional grip or friction, for example, for connecting or disconnecting the connector 105 (FIG. 1A). For example, two finger grooves 202 may be located on opposite sides of the source conduit connector 125.

[0043] In the illustrated embodiment, the source catheter connector 125 includes a plurality of locking tabs 151 and alignment tabs 152 for receiving the connection adapter 140 (FIG. 1A). In FIG. 2A, two locking tabs 151 are formed on the inner surface of the source catheter connector 125 and configured to lock with locking recesses formed on the connection adapter 140. These locking tabs 151 may be formed opposite to each other.

[0044] In Figure 2A, the alignment tab 152 is formed by a single, continuous protrusion or ridge on the inner surface of the source conduit connector 125. In one embodiment, this single, continuous protrusion or ridge alternates from a first distance toward the terminal orifice 150 of the source conduit connector 125 to a second distance away from the terminal orifice 150. The continuous protrusion or ridge may be cup-shaped or saddle-shaped, having a plurality of alternating valleys 215 and peaks 220. The peaks 220 are configured to guide a plurality of fingers of the connection adapter 140 into the valleys 215, wherein the locking tabs 151 can lock with locking recesses on the fingers. For example, the peaks 220 may be inclined toward the valleys 215 so that when the fingers are inserted into the source conduit connector 125, they are guided toward the valleys 215 by the ramp of the peaks 220.

[0045] In Figure 2A, the source conduit connector 125 includes an optional sensor port 130 for receiving the sensor probe 135. In the embodiment shown in Figure 2A, the sensor port 130 is positioned near or substantially adjacent to the terminal orifice 150. By placing the sensor port 130 close to the orifice 150, the sensor probe 135 can sample the airflow closer to the patient. Such sampling can provide a more accurate measurement of the airflow received by the patient. For example, if the sensor probe 135 is positioned further away from the patient, there may be a greater difference between the sampled airflow and the airflow inhaled by the patient. Therefore, airflow that appears to be within the patient's comfort zone (e.g., based on temperature or humidity) may cause discomfort because the measured airflow differs from the inhaled airflow. In one example, the airflow source 115 may include a heating element that warms the air, but the airflow temperature drops rapidly as it leaves the source 115. Therefore, in one embodiment, the sensor should be placed as close to the patient as possible to obtain more accurate results. Similarly, humidity changes occur very rapidly due to condensation. Likewise, the closer the sensor is to the patient, the more accurate its measurements will be. Clearly, by positioning the sensor probe 135 near the orifice 150 or toward the patient or nasal cannula 110, similar benefits can be obtained without using an optional sensor port 130. This can be achieved, for example, by replacing the sensor port with an integrated sensor as described below.

[0046] As shown in Figure 2A, sensor probe 135 is positioned within the gas flow within gas delivery conduit 100 to sample, measure, and / or analyze the gas flow. Sensor probe 135 may include any type of sensor, such as a temperature sensor, thermistor, flow meter, or sensors for oxygen (O2), carbon dioxide (CO2), nitrous oxide, and / or humidity. Sensor probe 135 may be reusable or disposable, and may be detachable or integrated with a conduit connector. Sensor probe 135 may be connected to a monitoring system having one or more processors for analyzing measurements, and the sensor probe may communicate with the monitoring system via cable or wirelessly. The monitoring system may include a display or other output device (e.g., speaker, alarm, or wireless transmitter) for displaying measurements or issuing alarms. The sensor probe 135 and / or monitoring system may include a storage device, such as an electrically erasable programmable read-only memory (EEPROM), an erasable programmable read-only memory (EPROM), flash memory, non-volatile memory, or the like. The sensor probe 135 may include a plurality of conductors for transmitting signals to and from its components, including sensing component conductors and memory device conductors.

[0047] In some implementations, sensor port 130 is configured to accept different types of sensor probes 135, thereby allowing sensor probes 135 to be replaced based on current use. For example, a humidity sensor may be used during humidification therapy, while an oxygen sensor may be used during oxygen therapy.

[0048] In some embodiments, there may be only a single locking tab 151 or three or more locking tabs 151. In some embodiments, these alignment tabs 152 may be formed by multiple protrusions or discontinuous ridges, rather than by a single continuous protrusion. For example, two unconnected peaks 220 may be formed on opposite sides of the inner surface of the source catheter connector 125. In some embodiments, the source catheter connector 125 may include alignment tabs 152 or locking tabs 151.

[0049] Figures 2B-2G show various views of the source catheter connector 125 of Figure 1C. This embodiment shares many of the structures and features discussed above with respect to the source catheter connector 125 of Figure 1A.

[0050] Figure 2B shows a perspective view of the source conduit connector 125 facing the terminal orifice 150, and illustrates a locking tab 151 and an alignment tab 152 formed on the inner surface.

[0051] Figure 2C shows a side perspective view of the source conduit connector 125, showing the source orifice 145.

[0052] Figure 2D shows a side view of the source conduit connector 125, illustrating the source port 145, the terminal port 150, the finger slot 202, and the sensor port 130.

[0053] Figure 2E shows a cross-sectional view of the source conduit connector 125 taken along the line indicated in Figure 2D. Figure 2E shows the source orifice 145, the terminal orifice 150, and the locking tab 151 and alignment tab 152 on the inner surface.

[0054] Figure 2F shows a view of the source conduit connector 125 facing the terminal port 150, showing the sensor port 130 and the locking tab 151 and alignment tab 152 on the inner surface.

[0055] Figure 2G shows a view of the source conduit connector 125 facing the sensor port orifice, showing the orifice of the sensor port 130, which opens into the body of the source conduit connector 125. In Figure 2G, the sensor port 130 is shown substantially adjacent to and perpendicular to the terminal orifice 150, and away from the source orifice 145.

[0056] Figures 3A and 3B show perspective views of the connector 140 of Figure 1A from the side of the source port 305 and the side of the terminal port 310, respectively. In the illustrated embodiment, the connector 140 includes a generally cylindrical conduit with two locking fingers 153 extending from the source port 305. These locking fingers 153 may be spaced apart to form an insertion port 312 for engaging a sensor probe 135 (Figure 1A) between the fingers 153. The insertion port 312 provides an opening through which a portion of the sensor probe 135 extends into the gas delivery conduit 100 to sample airflow within the gas delivery conduit 100 (Figure 1A). The insertion port 312 may also allow the sensor probe 135 to be positioned closer to the nasal cannula 110 (Figure 1A), for example, by allowing the connector 140 to extend around or above the sensor probe 135 toward the airflow source 115 (Figure 1A). In one embodiment, the insertion port 312 allows the sensor probe 135 to be placed closer to the patient while simultaneously allowing a portion of the connection adapter 140 to engage with the source catheter connector 125 (FIG. 1A). For example, without the insertion port 312, the sensor probe 135 might have to be placed beyond the end 314 of the connection adapter 140, further away from the nasal cannula 110, which could eliminate, suppress, or reduce some of the potential benefits of placing the sensor probe 135 closer to the patient discussed above.

[0057] In some embodiments, each locking finger 153 includes a locking recess 154 formed on the outer surface of the locking finger 153. In one embodiment, the locking recesses 154 are configured to lock with the locking tabs of the locking source conduit connector 125. In some embodiments, the locking fingers 153 comprise a flexible or semi-rigid material such that sufficient longitudinal force can cause the locking recesses 154 to pass through the locking tabs 151 of the source conduit connector 125, thereby releasing the connection adapter 140 from the source conduit connector 125. For example, pushing the connection adapter 140 into the source conduit connector 125 (during assembly or connection) or pulling the adapter 140 out (during disconnection) can cause the locking tabs of the source conduit connector 125 to engage or disengage with the locking recesses 154 of the locking fingers 153.

[0058] The connector 140 may include a locking channel 160 formed circumferentially along its outer surface. In FIG. 3A, the edge of this channel is defined by collars 320, 325 at the source and terminal orifices. For example, a ridge on the terminal conduit connector 120 (FIG. 1A) may lock into the channel 160. For example, pushing the connector 140 into the terminal conduit connector 120 (during assembly or connection) or pulling the connector 140 out (during disconnection) may cause the ridge of the terminal conduit connector 120 to engage or disengage with the locking channel 160. Due to longitudinal forces (e.g., forces along the axis of the conduit 100), these collars may prevent or inhibit disconnection of the ridge while allowing the ridge to rotate along the locking channel 160. In some embodiments, the terminal collar 320 comprises a flexible or semi-rigid material such that sufficient longitudinal force allows the ridge to pass through the collar 320 and release the connector 140 from the terminal conduit connector 120.

[0059] The connector 140 may have one or more optional spikes 330, which are formed longitudinally on the inner surface of the connector. The spikes 330 may provide rigidity to the connector and, in one embodiment, are evenly spaced along the inner circumference of the connector 140. In one embodiment, the spikes 330 taper and may provide greater rigidity at one end than the other. For example, the source orifice 305 side of the connector 140 may require greater flexibility for attachment and / or disengagement from the source conduit connector 125, and the spikes 330 may taper toward the source orifice 305 (in height or width).

[0060] In some embodiments, the connector 140 may have one, two, three, four or more locking fingers 153 or spikes 330. In some embodiments, other types of connection mechanisms may be used, such as threaded mechanisms, pinion mechanisms, friction fits, spring rings and / or adhesive or other chemical joints.

[0061] In some implementations, different types of connector adapters can be provided for connecting different types of catheter connectors. For example, a ventilator catheter may have a different type of source catheter connector than a humidifier catheter. By changing the connector adapter, the same nasal cannula can be connected to the ventilator catheter or humidifier catheter. By providing interchangeable connector adapters, the nasal cannula does not need to be changed, thereby minimizing patient discomfort by eliminating or reducing the need to change the nasal cannula attached to the patient. Similarly, by changing the adapter, different types of terminal catheter connectors can be connected to the same type of source catheter connector. For example, a nasal cannula can be replaced with a mask with a different type of terminal catheter connector by attaching the mask to the same humidifier using a different connector adapter. The interchangeability of connectors can potentially accelerate the setup of gas delivery catheters, which may be particularly advantageous in emergency situations.

[0062] Figures 3C-3G show various views of the connection adapter 140 of Figure 1C. This embodiment shares many of the structures and features discussed above with respect to the connection adapter 125 of Figure 1A.

[0063] Figure 3C shows a top view of the connector 140, illustrating two locking fingers 153 extending from the body of the connector 140, and two locking recesses 154 formed on the outer surface of the locking fingers 154. In some embodiments, raised strips 350 form the bottom boundaries of the recesses 154 corresponding to the locking fingers 153. Each raised strip 350 can provide additional support and / or rigidity to each locking recess 350, thereby allowing for a more secure connection between such locking recesses and the corresponding locking tabs.

[0064] Figure 3D shows a side view of the connector 140, illustrating a locking finger 153 extending from the body of the connector 140, a locking recess 154 formed on the outer surface of the locking finger, and a locking channel 160 formed along the circumference of the outer surface of the connector. In the embodiment of Figure 3D, the locking finger 153 widens from its end 314 towards its bottom 340. By widening at its bottom, where the finger 153 connects to the body of the connector 140, the strength of the locking finger 153 is increased, making it more difficult to deform the locking finger 153 and to disengage it when engaged with the locking tab 151 of the source conduit connector 125. Additionally, the raised strip 350 can also increase the strength of the locking finger 153.

[0065] Figure 3E shows a perspective view of the orifice of the terminal conduit connector 120 facing the connector adapter 140. Figure 3E also shows the locking finger 153, the locking recess 154, the locking channel 160, and the longitudinally formed protrusions 330 on the inner surface of the connector adapter.

[0066] Figure 3F shows a front view of the orifice of the connector 140 facing the terminal conduit connector 120. Figure 3G shows a front view of the orifice of the connector 140 facing the source conduit connector 125. A spike 330 is shown formed on the inner surface of the connector 130.

[0067] Figures 4A and 4B show perspective views of the terminal conduit connector 120 from the source port 155 side, and a top view of the terminal conduit connector 120 in Figure 1A. Figure 4A shows the terminal conduit connector 120 without the connector adapter 140 inserted, while Figure 4B shows the terminal conduit connector 120 with the connector adapter 140 inserted. In the illustrated embodiment, the terminal conduit connector 120 includes a plurality of circumferentially spaced ridges 405 along the inner surface of the terminal conduit connector 120. In one embodiment, these ridges 405 are formed longitudinally by surrounding cuts or as protrusions or tabs formed axially along the terminal conduit connector 120. The ridges 405 and the surrounding cuts can reduce frictional engagement with the connector adapter 140, thereby improving rotatability. The ridges 405 may gradually narrow in width or height. This gradual narrowing allows for insertion of the connector 140 with less force, while requiring more force to remove the connector 140 as the larger surface area of ​​each locking tab engages with the terminal collar 320 (FIG. 3A) of the connector 140. In one embodiment, a locking groove 410 is formed along the circumference of the terminal conduit connector 120 and configured to engage with the terminal collar 320 of the connector 140, thereby increasing the longitudinal force required to disengage the terminal conduit connector 120 from the connector 140.

[0068] In one embodiment, the terminal catheter connector 120 includes a terminal orifice 165 configured to receive a nasal cannula 110 (FIG. 1A). The terminal orifice 165 may include two openings for receiving a dual-cannula system, each cannula being connected at its opposite end to a pin for insertion into a patient's nostril. In the illustrated embodiment, these openings are optionally surrounded by an angled surface configured to concentrate airflow into the dual-cannula system, thereby improving airflow. The terminal catheter connector 120 may also include one or more finger-shaped grooves 415 formed on the outer surface of the terminal catheter connector 120 to provide the user with additional grip or friction, for example, for connecting or disconnecting the connector 105 (FIG. 1A). In FIG. 4A, the plurality of finger-shaped grooves 415 are spaced apart along the outer circumference of the terminal catheter connector 120.

[0069] Other configurations of the terminal conduit connector 120 are possible. For example, in some embodiments, the locking tab 405 is a single, continuous ridge. In other embodiments, the ridge 405 is formed perpendicularly or at an angle to the axis of the terminal conduit connector 120. In some embodiments, the locking groove 410 is not included. The orifice 165 can be a single opening. For example, the orifice 165 can be configured to receive a single conduit leading to a face mask.

[0070] Figures 4C-4G show various views of the terminal catheter connector 120 of Figure 1C. This embodiment shares many of the structures and features discussed above with respect to the terminal catheter connector 120 of Figure 1A.

[0071] Figure 4C shows a side view of the terminal catheter connector 120, illustrating the terminal port 165 and source port 155 for receiving a nasal cannula. A first portion of the body of the terminal catheter connector 120 that receives the connection adapter 140 is at a first height. A second portion of the body of the terminal catheter connector 120 that receives the nasal cannula is at a second, lower height.

[0072] Figure 4D shows a top view of the terminal conduit connector 120, illustrating the terminal orifice 165 and the source orifice 155. The first portion of the body of the terminal conduit connector 120 has a first width, while the second portion of the body has a second, narrower width.

[0073] Figure 4E shows a front view of the terminal orifice 165. Figure 4F shows a front view of the source orifice 155, illustrating a plurality of ridges 405 spaced circumferentially along the inner surface of the terminal conduit connector 120.

[0074] Figure 4G shows a perspective view of the terminal conduit connector 120. The connector 120 includes at least one lip positioned around the first source orifice 155. Figure 4G shows one lip. This lip provides a sealing surface for sealing with other connectors. This lip is also shown in Figure 5A.

[0075] Figure 5 shows a longitudinal cross-sectional view of the connector 105 embodiment of Figure 1A. Figure 5 shows the terminal collar 320 of the connection adapter 140, which engages with the locking groove 410 of the terminal conduit connector 120. A portion of the sensor probe 135 engages between the fingers 153 of the connection adapter. Figure 5 shows the fingers 153 engaging with the alignment tabs 152. In one embodiment, the source conduit connector 125 includes an inner cylinder 505 within an outer cylinder 510, thereby forming an insertion groove 515 for receiving the delivery conduit 115 (Figure 1A). In one embodiment, pressure from the inner and outer cylinders maintains pressure engagement with the delivery conduit 115, thereby keeping the delivery conduit 115 connected to the source conduit connector 125.

[0076] Figure 6 shows a cross-section along axis 167 of Figure 1B facing the nasal cannula 110 (Figure 1A), and illustrates the engagement of the connector 140 with the source catheter connector 125. In the illustrated embodiment, the source catheter connector 125 and the terminal catheter connector 120 are attached via the connector 140. Locking tabs 151 formed on the inner surface of the source catheter connector 125 engage with recesses 154 on the fingers 153 of the connector 140. This engagement prevents longitudinal movement of the adapter and limits accidental disengagement of the connector 105 (Figure 1A). Aligning the tabs 152 allows the fingers 153 to be guided into engagement positions.

[0077] As illustrated in Figure 6, sensor port 130 provides a pathway for sensor probe 135 to access the airflow within the gas delivery conduit 100 (Figure 1A). The airflow from the airflow source passes through sensor probe 135 and then exits through terminal orifice 165 of terminal conduit connector 120.

[0078] It is evident that there are many possible implementations for connector 105. For example, in some implementations, connector 105 does not include connector adapter 140 or another component. In some implementations, multiple elements, such as tabs, protrusions, recesses, channels, or slots, are located on different components. For example, although the above disclosure describes a first element (e.g., a protrusion or tab) of a connection mechanism being positioned on a first component, and a second element (e.g., a recess, channel, or slot) of the connection mechanism being positioned on a second component, in some implementations, the positions of these elements can be switched, wherein the first element is located on the second component, and the second element is located on the first component. In some implementations, certain elements may not be included. In one implementation, a first connector component may be configured for attachment to a second connector component, while in another implementation, the second connector component may be configured for attachment to a first connector component.

[0079] In some embodiments, different types of connections may be used to attach the components of the connector 105. For example, adhesives or other chemical agents may be used to permanently bond some components together. In other instances, different mechanical connection mechanisms may be used, such as snap-fit, threaded, friction fit, or spring ring. The components of the connector 105 may be made of various types of flexible, semi-rigid, or rigid materials. For example, the connector adapter 104 and the source conduit connector 125 may comprise polypropylene, and the terminal conduit connector 120 may comprise THERMOLAST. Other materials may be used, such as plastics, thermoplastics, silicone, glass-filled nylon, metals, spring steel, polycarbonate, PVC, polyethylene, rubber (e.g., natural or vulcanized), polyurethane, or the like. For example, in one embodiment, the connector adapter 140 comprises ABS plastic, the source conduit connector 125 comprises polyethylene, and / or the terminal conduit connector 120 comprises a thermoplastic elastomer.

[0080] In some embodiments, some mechanisms of the releasable connection mechanism can be stronger than others. In one embodiment, the connection formed by the connection adapter 140 and the source catheter connector 125 is weaker than the connection formed by the connection adapter 140 and the terminal catheter connector 120. Therefore, pulling apart the catheter connectors 120, 125 causes the connection adapter 140 to disengage from the source catheter connector 125 while remaining connected to the terminal catheter connector 120. This configuration can facilitate altering the patient interface by allowing another patient interface to attach smoothly or quickly to the source catheter connector 125. Other configurations are possible; for example, the connection adapter 140 can be configured to remain connected to the source connecting catheter 125.

[0081] In some embodiments, the connection of connector 105 is configured to allow components of connector 150 to connect or release quickly. For example, these components may be configured to connect or release by a single movement (e.g., when pushed together or pulled apart). These components may be configured to self-align during engagement, such that the connection mechanisms of these components automatically align. In another example, the connection of connector 105 to gas delivery conduit 115 (FIG. 1A) and / or nasal cannula 110 may be stronger than other connections (e.g., connections to adapter 140), such that longitudinal forces applied to gas delivery conduit 100 cause the other, weaker connections to break first. In some embodiments, the connection to gas delivery conduit 115 and / or nasal cannula 110 is permanent or semi-permanent to eliminate or reduce accidental disconnection.

[0082] Other embodiments of connector 105 are possible. In some embodiments, terminal opening 165 includes a single opening, two openings, or three or more openings. One, two, or more finger slots 415 (FIG. 4A) may be present externally. In some embodiments, the gas delivery conduit 100 or multiple portions thereof may be attached to the patient by means of a tether (e.g., around the patient's neck), a clip, or other fastening mechanism. The seal formed by these components may be airtight or may allow some air leakage. In some embodiments, elements of connector 105 may be painted in different colors to indicate the size of the connector. For example, red may indicate an adult-sized connector, while blue may indicate an infant connector. In some embodiments, the gas delivery conduit 100 may include one or more spring-loaded tubing sections that may increase flexibility.

[0083] The components of connector 105 can be formed in various sizes depending on their intended use. For example, a connector for a gas delivery catheter 100 for children or infants may be smaller than a connector for a gas delivery catheter 100 for adults. In some embodiments, the source catheter connector 125 has an outer diameter ranging from 5 to 30 mm, but in other embodiments this diameter may be larger or smaller. In one embodiment, the outer diameter is approximately 15 mm. Other connector components 105 can be sized to correspond to the source catheter connector 125. For example, other components may be sized to be approximately the same as the source catheter connector 125 for engagement.

[0084] Figure 7 illustrates an alternative connector embodiment 700 of the connector of Figure 1A. In Figure 7, the terminal catheter connector 705 includes a double ball-and-socket connection 710 for individually connecting multiple nasal cannulas to the terminal catheter connector. These ball-and-socket connections 710 are movable independently of each other. This allows the nasal cannulas to be disassembled without twisting or tangling, thereby facilitating adjustment of the nasal cannulas. Furthermore, while longer cannulas typically allow for a greater degree of adjustment of the nasal cannulas, the greater degree of freedom of movement provided by the ball-and-socket connections 710 could potentially provide a similar degree of adjustment while allowing the use of shorter cannulas.

[0085] Figure 8 illustrates an alternative connector embodiment 800 of the connector of Figure 1A. In Figure 8, the terminal catheter connector 805 and the sensor probe 810 are connected substantially perpendicular to the source catheter connector 815. The source catheter connector 815 is connected to a rotating conduit 820, which in turn is connected to a gas delivery conduit 825. With the sensor probe, terminal catheter connector, and source catheter connector rotatably attached to the gas delivery conduit via the rotating conduit 820, the connector can be laid flat on the bed, potentially increasing patient comfort or keeping the connector in an unobstructed position. In the illustrated embodiment, the connector 800 is shaped to form a substantially 90-degree angle, thereby redirecting the airflow above the sensor probe 810 and directing the airflow into the nasal cannula 830. This redirection of the airflow advantageously allows the sensor probe 810 to detect the disconnection of the terminal catheter connector 805 by detecting changes in the airflow. For example, sensor probe 810 can detect changes in the direction, speed, or components of the airflow (such as humidity or temperature) and determine that the terminal duct connector 805 is no longer attached in order to redirect the airflow.

[0086] Figure 9 illustrates an alternative connector implementation 900 of the connector in Figure 1A. In Figure 9, the terminal catheter connector 905 can be connected to the source catheter connector 910 substantially vertically or substantially straight. The dual redirection of the terminal catheter connector 905 can provide greater flexibility in adjusting the nasal cannula 920.

[0087] The source catheter connector 910 may include an orifice 930 through which a sensor probe 925 can partially extend into the terminal catheter connector 910, thus positioning the sensor probe 925 closer to the point of entry for airflow into the cannula. In the illustrated embodiment, the orifice 930 is recessed to allow the sensor probe 925 to extend through it. This allows the sensor probe 925 to collect more accurate measurements of the temperature, humidity, or other parameters of the gas inhaled by the patient.

[0088] Figure 10 illustrates an alternative connector embodiment 1000 of the connector of Figure 1A. In Figure 10, a terminal catheter connector 1005 is connected to a connection adapter 1010, which is connected to a source catheter connector 1015. The connection adapter 1010 includes a collar 1020 having a larger diameter than the adjacent terminal and source catheter connectors. Therefore, when the connector is assembled, a portion of the collar 1020 extends over the outer housing of the connected terminal and source catheter connectors and remains a visible ring. The collar 1020 can be colored to indicate the size information of the connector 1000. The collar 1020 can also provide better frictional retention to the user, thereby allowing a shorter connector to provide a similar amount of frictional grip, which can facilitate the attachment and / or disengagement of these connector components.

[0089] Figures 11A and 11B illustrate an alternative connector embodiment 1100 of the connector in Figure 11A. In Figure 11, a terminal conduit connector 1105 is fitted within a source conduit connector 1110, while a threaded cap 1115 fits onto the terminal conduit connector 1105 and engages with a threaded end 1120 of the source conduit connector. The threaded cap 1115 engages with a ring of the terminal conduit connector 1125 and holds the terminal conduit connector pressed against the source conduit connector. A plurality of flaps 1126 formed on the body of the terminal conduit connector 1105 can provide a space between the exterior of the terminal conduit connector 1105 and the interior of the source conduit connector 1110.

[0090] In one embodiment, the threaded cap 1115 engages only with some of the threaded grooves on the threaded end 1120 of the source catheter connector. For example, if the threaded end 1120 has six threaded grooves, then the threaded cap 1115 is configured to engage only with three of these grooves, leaving the other three threaded grooves unengaged. This partial engagement of the threads allows condensate collected within the connector to escape along the unengaged threads, along an outflow path 1135, thereby preventing or inhibiting condensate from entering the cannula 1130. The outflow path 1135, or discharge channel, may be partially formed by the space 1137 between the exterior of the terminal catheter connector 1105 and the interior of the source catheter connector 1110.

[0091] Figure 12 illustrates an alternative connector embodiment 1200 of the connector of Figure 1A. In Figure 12, a terminal conduit connector 1205 is connected to a connection adapter 1210, which is connected to a source conduit connector 1215. The connection adapter includes an end 1220 for connection to the terminal conduit connector 1205, for example by thread or friction engagement. A source port 1225 of the connection adapter 1210 mates with the source conduit connector 1215.

[0092] Figure 13 illustrates an alternative connector embodiment 1300 of the connector of Figure 1A. In Figure 13, a terminal catheter connector 1305 is connected to a source catheter connector 1310. A plurality of locking tabs 1315 formed on a connecting end of the terminal catheter connector engage with other locking tabs within the source catheter connector 1310. Twisting the terminal catheter connector 1305 relative to the source catheter connector 1310 disengages the locking tabs 1315, thereby allowing the connector 1300 to be disassembled.

[0093] Figure 14 illustrates an alternative connector embodiment 1400 of the connector of Figure 1A. In Figure 14, a terminal catheter connector 1405 is connected to a source catheter connector 1410. A locking thread 1415 formed on a connecting end of the terminal catheter connector engages with the source catheter connector. Twisting the terminal catheter connector 1405 relative to the source catheter connector 1410 disengages the locking thread 1415, thereby allowing the connector 1400 to be disassembled.

[0094] In one embodiment, one side of the conduit connector 1410 can be configured to engage with another component using a unique or proprietary connection mechanism, while the other side of the conduit connector 1410 uses a general or standard connection mechanism. This general connection allows connection to a variety of components manufactured by different manufacturers. Conversely, the proprietary connection only allows connection to components from a single manufacturer or a selected set of manufacturers. Providing two different types of connectors is advantageous when one component requires higher precision than the other, and a specific component is needed to allow the use of components with known or predetermined characteristics. Simultaneously, the general connection provides greater interoperability. In an exemplary embodiment, the general connection 1420 uses a friction fit for attachment, while the proprietary connection 1425 is connected with a locking thread 1415.

[0095] Figure 15 illustrates an alternative connector embodiment 1500 of the connector of Figure 1A. In Figure 15, a terminal conduit connector 1505 is connected to a source conduit connector 1510. The edge of the source conduit connector 1510 can engage with a locking groove 1512 on the terminal conduit connector 1505. An O-ring seal 1515 forms a seal between the terminal conduit connector and the source conduit connector. In the illustrated embodiment, a sensor port 1520 is formed on the source conduit connector, away from the connection between the source conduit connector and the terminal conduit connector.

[0096] Figure 16 illustrates an alternative connector embodiment 1600 of the connector of Figure 1A. In Figure 16, a terminal catheter connector 1605 is connected to a connection adapter 1610, which is connected to a source catheter connector 1615. In the illustrated embodiment, the connection adapter 1610 includes three fingers 1620 for engaging with the source catheter connector 1615. These fingers 1620 may be spaced apart to form an insertion port 1630 for fitting a sensor probe 1605 between two of the fingers 1620. The insertion port 1630 allows the sensor probe 1605 to be positioned closer to the nasal cannula 1635. For example, without this insertion port 1630, the sensor probe 1605 might have to be placed beyond the end of the connection adapter 1610, further away from the nasal cannula 1635.

[0097] Figure 17 illustrates one embodiment of a catheter connector 1700 having an integrated sensor probe 1705. The sensor probe 1705 is positioned to engage in an insertion orifice formed by two finger-shaped elements of a connection adapter (e.g., connection adapter 140 of Figure 1). By engaging in an insertion orifice, the sensor probe 1705 can be positioned closer to the nasal cannula. In the illustrated embodiment, the sensor probe 1705 is positioned at a distance approximately equal to the distance to the orifice 1707 of the catheter connector 1700 and to the locking tab 1720. The sensor probe 1705 engages between the finger-shaped elements when the finger-shaped elements of the connection adapter engage with the locking tab 1720. In one embodiment, the catheter connector 1700 does not have a sensor port.

[0098] Figures 18A-18C show different views of one embodiment of a conduit connector 1800 having a receptacle for a removable sensor probe. In the embodiment shown in Figure 18A, the receptacle includes channels 1805, 1810 for receiving the sensor probe. Channels 1805, 1810 may extend partially or completely within the inner surface of the conduit connector 1800. The sensor probe may be disc-shaped, rectangular, oval, rhomboid, or any other shape configured for reception by the receptacle. In one embodiment, the sensor probe includes a plurality of alignment tabs configured to engage with channels 1805, 1810. These alignment tabs may be configured to position the sensor probe at a predetermined location within the conduit connector 1800, such as a location where sensor measurements can be obtained more efficiently, or a location within an insertion orifice formed by one or more locking fingers of a connection adapter.

[0099] In one embodiment, the receptacle may include a hook, notch, tab, wall, or other structure for locking or securing the sensor probe in place once it reaches the predetermined position. In some embodiments, in addition to or as an alternative to channels 1805, 1810, the receptacle may include other structures for receiving and / or securing the sensor probe. For example, the receptacle may include a plurality of ridges configured to engage with channels on the sensor probe. The conduit connector 1800 may also include one or more locking tabs 1820.

[0100] Figure 18B shows a rear perspective view of the embodiment of Figure 18A, and Figure 18C shows a cross-sectional view thereof. In the illustrated embodiment, an insertion slot for a second conduit (e.g., a hose or delivery pipe) is formed by the space between the outer walls 1825, 1830 and the inner walls 1827, 1832 of the conduit connector 1800. In the illustrated embodiment, one end of the outer wall extends beyond one end 1822 of the inner wall. However, in other embodiments, the inner and outer walls may have the same length, or the inner wall may extend beyond the outer wall.

[0101] Figures 19A-19B illustrate an alternative connector adapter embodiment configured for connection with the source conduit connector embodiment of Figures 20A-20B.

[0102] Figure 19A shows a side view of a connection adapter facing one of the two locking fingers 153 and its locking recess 154. As shown in the various embodiments disclosed herein, a channel 160 formed on the body of the connection adapter provides an engagement surface for a corresponding terminal catheter connector. In Figure 19A, the locking recess 154 extends beyond the locking fingers 153 to provide engagement with an annular locking ring on the source catheter connector embodiments of Figures 20A-20B.

[0103] Figure 19B shows a perspective view of the connector of Figure 19A, illustrating the locking finger 153 and its locking recess 154.

[0104] Figures 20A-20B illustrate an embodiment of an alternative source conduit connector 125 having an annular hole for attachment to the alternative connector adapter embodiment of Figures 19A-19B.

[0105] Figure 20A shows a perspective view of the source conduit connector facing the terminal orifice 150. Formed within the inner surface of this source conduit connector is an annular locking ring 2005, which is formed by a raised strip extending circumferentially within the body of the source conduit connector. The locking recess 154 of the connector adapter in Figures 19A and 19B is configured to engage with the annular locking ring 2005 when the connector adapter is inserted into the source conduit connector.

[0106] Figure 20B shows a cross-sectional view taken along the section line indicated in Figure 20A. This cross-sectional view shows the annular locking ring 2005 formed on the inner surface of the source conduit connector.

[0107] Figures 21A-21D show different views of an embodiment of a nasal cannula 2100 connected to an airflow source via various connector embodiments discussed in this disclosure. In some embodiments, the nasal cannula is used for infants and young children.

[0108] Figure 21A shows a top perspective view of the nasal cannula 2100 facing the patient. The nasal cannula 2100 includes two pins 2105a, 2105b that fit into the patient's nostrils. An air passage 2110 extends from the pins and is connected (e.g., via connector 105 of Figure 1A) to an air source.

[0109] Figure 21B shows a top perspective view of the nasal cannula 2100 away from the patient. Figure 21B shows the two forks 2105a, 2105b and the two air passages 2110a, 2110b connected to the two forks.

[0110] Figure 21C shows a side view of the nasal cannula 2100, showing one of the needles in the needle 2105 and one of the tubes in the airway 2110.

[0111] Figure 21D shows a bottom view of the nasal cannula 2100, showing the two forks 2105a and 2105b and the two air channels 2110a and 2110b connected to the two forks.

[0112] In some implementations, certain features may be associated with different components or omitted. For example, the connection mechanism in the terminal conduit connector 120 may be implemented by the source conduit connector 125, and / or the connection mechanism of the source conduit connector 125 may be implemented by the terminal conduit connector 120. In another example, the sensor port 130 may be located on the terminal conduit connector 120, rather than on the source conduit connector 125. Some features may be implemented by a different component (e.g., the terminal conduit connector 120, the source conduit connector 125, or the connection adapter 140) rather than by the component described above as implementing the feature.

[0113] The conditional language used herein, such as in particular “may,” “can,” “possibly,” “for example,” and the like, is generally intended to convey, unless otherwise expressly stated or understood in the context of its use, that certain embodiments include, while other embodiments do not, certain features, elements, and / or states. Therefore, such conditional language is not generally intended to imply that such features and / or elements are required in any way for use in one or more embodiments.

[0114] Although the foregoing disclosure has described certain preferred embodiments, those skilled in the art will readily understand other embodiments from the disclosure herein. It is anticipated that the various aspects and features of this disclosure can be practiced separately, combined together, or substituted for one another, and that such features and aspects can be combined and sub-combined in various ways, all of which remain within the scope of this disclosure. Therefore, this disclosure is not intended to be limited to the description of preferred embodiments, but rather to be defined with reference to the appended claims.

[0115] The foregoing description of this invention includes the preferred form of the invention. Modifications may be made to this invention without departing from its scope.
