[0035] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0036] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", "axial", "radial", "circumferential" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0037] In the prior art, especially in the critical care medicine department, patients often need to have a gastrointestinal tube placed in one of their nasal cavities for treatment due to their condition. When such patients receive high-flow nasal oxygen therapy, multiple treatment tubes will need to be inserted into one of their nasal cavities at the same time, which will cause one of their nasal cavities to be filled with treatment tubes, causing discomfort to the patient. In severe cases, it will also affect the use of the treatment tube and increase the difficulty of inserting the treatment tube.

[0038] At the same time, when existing patients receive nasal high-flow oxygen therapy, due to poor patient compliance and other reasons, they are prone to mouth breathing. At this time, the high-flow nasal airflow will overflow from the patient's mouth, resulting in a decrease in the patient's positive airway pressure effect and accelerated moisture discharge, making the patient's mouth drier. This will not only reduce the treatment effect, but also cause discomfort to the patient.

[0039] In order to solve the above problems, the present application proposes an oxygen delivery mask 1000.

[0040] The oxygen delivery mask 1000 according to an embodiment of the present invention will be described below with reference to the accompanying drawings.

[0041] Combination Figure 1 , Figure 2 and Figure 4 As shown, the oxygen delivery mask 1000 according to the embodiment of the present invention includes: a mask body 100 and a nasal plug assembly 400.

[0042] Among them, Figure 1 As shown, the mask body 100 is provided with an oxygen delivery port 110. The oxygen delivery port 110 is used to achieve communication between the inner and outer sides of the mask body 100, so as to facilitate oxygen delivery to the patient through the mask body 100, so as to achieve the purpose of nasal high-flow oxygen therapy for the patient and facilitate the patient's recovery.

[0043] It should be noted that the inner side of the mask body 100 mentioned here can be understood as the side of the mask body 100 facing the patient's face when the patient wears the mask body 100; correspondingly, the outer side of the mask body 100 can be understood as the side of the mask body 100 facing away from the patient's face when the patient wears the mask body 100.

[0044] like Figure 1 , Figure 2 and Figure 4 As shown, the nasal plug assembly 400 includes a matching seat 410 and a first oxygen delivery tube 420. The matching seat 410 is detachably connected to the inner side of the mask body 100, and the first oxygen delivery tube 420 is arranged on the matching seat 410 and connected to the oxygen delivery port 110. In other words, the nasal plug assembly 400 is detachably connected to the side of the mask body 100 facing the patient's face, so that the first oxygen delivery tube 420 can be easily inserted into the patient's nasal cavity. Since the first oxygen delivery tube 420 is connected to the oxygen delivery port 110, oxygen can be delivered to the first oxygen delivery tube 420 through the oxygen delivery port 110, so as to achieve the purpose of high-flow nasal oxygen therapy for the patient.

[0045] At the same time, by arranging first oxygen delivery tube 420 on matching seat 410, matching seat 410 is used to support first oxygen delivery tube 420, thereby improving the position stability of first oxygen delivery tube 420, thereby ensuring the working performance of first oxygen delivery tube 420.

[0046] It is worth noting that the present application detachably connects the mating seat 410 to the inner side of the mask body 100, so that the nasal plug assembly 400 is detachable relative to the mask body 100. In this way, when the patient needs to use the oxygen delivery mask 1000 for nasal high-flow oxygen therapy, the appropriate nasal plug assembly 400 can be replaced according to the patient's own situation, so as to avoid inserting multiple treatment tubes into one side of the patient's nasal cavity at the same time to a certain extent, ensure the patient's comfort during nasal high-flow oxygen therapy, improve the patient's use experience, and at the same time, avoid squeezing multiple treatment tubes against each other to a certain extent to affect the use and insertion of the treatment tubes.

[0047] In some embodiments, in combination Figure 2 and Figure 3 As shown, the nasal plug assembly 400 has two styles, one of which is as shown in FIG. Figure 2 As shown, two first oxygen delivery tubes 420 are provided on the mating seat 410. This type of nasal plug assembly 400 is used when no other treatment tubes (such as stomach tubes or intestinal tubes) are required to be placed in both nasal cavities of the patient. Another type of nasal plug assembly 400 is as shown in FIG. Figure 3 As shown, a first oxygen delivery tube 420 is provided on the matching seat 410. This nasal plug assembly 400 is used when a gastric tube or an intestinal tube needs to be placed in one side of the nasal cavity of the patient.

[0048] In addition, by setting the mating seat 410 to be detachably mated with the mask body 100, it is also convenient to maintain the nasal plug assembly 400 and ensure the working performance of the nasal plug assembly 400. At the same time, the nasal plug assembly 400 can be replaced when it is damaged. This can avoid replacing the entire oxygen delivery mask 1000 due to damage to the nasal plug assembly 400, thereby reducing the use cost of the oxygen delivery mask 1000.

[0049] As can be seen from the above structure, the oxygen delivery mask 1000 of the embodiment of the utility model, by providing the oxygen delivery port 110 and the first oxygen delivery tube 420 that cooperate with each other, enables the oxygen delivery mask 1000 to implement nasal high-flow oxygen therapy for the patient, which is beneficial to the patient's rehabilitation treatment.

[0050] At the same time, by detachably connecting the mating seat 410 to the inner side of the mask body 100, the nasal plug assembly 400 is made detachable relative to the mask body 100, thereby facilitating the replacement of the nasal plug assembly 400. This reduces the difficulty of replacing the nasal plug assembly 400 and enables nasal plug assemblies 400 of different specifications to be replaced according to different patients, thereby expanding the scope of application of the oxygen delivery mask 1000 and, to a certain extent, avoiding the simultaneous insertion of multiple treatment tubes into one side of the patient's nasal cavity, thereby ensuring the patient's comfort during nasal high-flow oxygen therapy and improving the patient's usage experience.

[0051] It is also worth noting that the oxygen delivery mask 1000 of the present application is provided with a mask body 100. Thus, when the oxygen delivery mask 1000 is used for nasal high-flow oxygen therapy, the mask body 100 can be used to cover the patient's mouth, so as to limit the nasal high-flow airflow and moisture to the vicinity of the patient's mouth and nose, so that the air pressure and humidity in the oxygen delivery mask 1000 can be appropriately increased, thereby avoiding, to a certain extent, the airway from being connected to the outside air and being unable to maintain positive airway pressure, solving the technical problem in the prior art of a decrease in the patient's positive airway pressure due to mouth breathing by the patient, and also allowing the patient's mouth and nose to always be in a relatively humid environment, thereby improving the patient's comfort experience.

[0052] In summary, the oxygen delivery mask 1000 of the present application can not only meet the needs of both patients with gastrointestinal tubes and patients without gastrointestinal tubes, but also solve the technical problem of decreased positive airway pressure in patients due to mouth breathing.

[0053] It can be understood that compared with the prior art, the oxygen delivery mask 1000 of the present application can not only realize nasal high-flow oxygen therapy for patients, but also can meet the needs of patients with gastrointestinal tubes and patients without gastrointestinal tubes, expand the scope of application of the oxygen delivery mask 1000 and ensure the comfort of patients, and at the same time solve the technical problem of decreased positive airway pressure of patients due to mouth breathing.

[0054] In some embodiments, the mask body 100 is made of a transparent material, so that when the oxygen delivery mask 1000 is used to supply oxygen to a patient, it is convenient for medical staff to observe the patient's oxygen inhalation.

[0055] In some embodiments, two styles of nasal plug assemblies 400 (a nasal plug assembly 400 with two first oxygen delivery tubes 420 provided on the matching seat 410 and a nasal plug assembly 400 with one first oxygen delivery tube 420 provided on the matching seat 410) have multiple sizes, such as: a large-sized nasal plug assembly 400, a medium-sized nasal plug assembly 400 and a small-sized nasal plug assembly 400, so that it is possible to replace a suitable nasal plug assembly 400 according to the height of the nasal cavity and nose bridge of different patients, thereby ensuring the effect of the nasal plug assembly 400 in delivering oxygen and improving the patient's usage experience.

[0056] Therefore, the present application can also realize replacement of nasal plug assemblies 400 of different sizes according to the nasal cavity and nose bridge height of different patients by setting the matching seat 410 to be detachably matched with the mask body 100, so as to ensure the effect of the nasal plug assembly 400 in delivering oxygen and enhance the patient's user experience.

[0057] In some embodiments, the oxygen delivery mask 1000 further includes a mounting seat 200, which is disposed on the inner side of the mask body 100, and the mating seat 410 is detachably connected to the mounting seat 200. In this way, the mounting seat 200 disposed on the inner side of the mask body 100 can be used to provide a mounting position for the mating seat 410 of the nasal plug assembly 400, thereby realizing a detachable connection between the mating seat 410 and the mask body 100, reducing the difficulty of connecting the mating seat 410 and the mask body 100, thereby reducing the difficulty of detaching the mating seat 410, so as to facilitate the removal of the nasal plug assembly 400.

[0058] At the same time, by setting the matching seat 410 on the mounting seat 200, on the one hand, the nasal plug assembly 400 can be set on the side of the mask body 100 facing the patient's face, which is convenient for the use of the nasal plug assembly 400; on the other hand, the mounting seat 200 can also be used to support the nasal plug assembly 400, thereby improving the position stability of the nasal plug assembly 400, thereby ensuring the working performance of the nasal plug assembly 400.

[0059] In some embodiments, in combination Figure 1 , Figure 2 and Figure 4As shown, the mounting seat 200 is a panel surrounding the oxygen delivery port 110, and the matching seat 410 has an escape channel 411 for escaping the panel, and the matching seat 410 is detachably connected to the panel through the escape channel 411. Thus, the detachable matching of the matching seat 410 and the mounting seat 200 is achieved, and while the mounting seat 200 is used to support the matching seat 410, the nasal plug assembly 400 can be easily removed, and the difficulty of replacing the nasal plug assembly 400 is reduced. In this way, while reducing the use cost of the oxygen delivery mask 1000, the nasal plug assembly 400 of different specifications can be replaced according to the patient's own situation, so as to avoid the simultaneous insertion of multiple treatment tubes in one side of the patient's nasal cavity, ensure the patient's comfort during nasal high-flow oxygen therapy, and at the same time, to a certain extent, avoid the squeezing of multiple treatment tubes to affect the use and insertion of the treatment tubes.

[0060] At the same time, by configuring the mounting base 200 as a panel surrounding the oxygen delivery port 110, the mounting base 200 can be prevented from blocking the oxygen delivery port 110, thereby facilitating the use of the oxygen delivery port 110 to deliver oxygen toward the patient, thereby ensuring the working performance of the oxygen delivery mask 1000.

[0061] In some embodiments, the mounting base 200 is formed into a "mouth"-shaped structure to surround the outer periphery of the oxygen delivery port 110. While providing a mounting position for the mating base 410, it can also prevent the mounting base 200 from blocking the oxygen delivery port 110, thereby facilitating the use of the oxygen delivery port 110 to deliver oxygen to the patient, thereby ensuring the working performance of the oxygen delivery mask 1000.

[0062] In some embodiments, Figure 4 As shown, the mating seat 410 is formed into a "C"-shaped structure to realize an avoidance channel 411 for avoiding the enclosure on the mating seat 410, thereby facilitating the detachable connection of the mating seat 410 to the enclosure through the avoidance channel 411, thereby reducing the difficulty of connecting the mating seat 410 with the mounting seat 200.

[0063] In some embodiments, the first oxygen delivery tube 420 is disposed on the matching seat 410 and connected to the avoidance channel 411. In this way, when the matching seat 410 is detachably connected to the enclosure through the avoidance channel 411, the first oxygen delivery tube 420 can be connected to the oxygen delivery port 110, so as to facilitate the use of the first oxygen delivery tube 420 to deliver oxygen toward the patient, thereby achieving the purpose of nasal high-flow oxygen therapy for the patient.

[0064] In some embodiments, Figure 4As shown, one of the inner wall of the avoidance channel 411 and the outer wall of the enclosure is provided with a slider 210, and the other is provided with a slide groove 4111, and the slider 210 can be slidably matched in the slide groove 4111. This realizes the sliding match between the matching seat 410 and the mounting seat 200, and then realizes the detachable match between the matching seat 410 and the mounting seat 200, which facilitates the removal of the nasal plug assembly 400, so as to facilitate the replacement of nasal plug assemblies 400 of different specifications according to different patients, thereby improving the patient's use experience.

[0065] In a specific example, Figure 4 As shown, a slide groove 4111 is provided on the inner wall of the avoidance channel 411, and a slider 210 is provided on the outer wall of the enclosure. The slider 210 can be slidably fitted in the slide groove 4111 to achieve detachable fitting of the fitting seat 410 and the mounting seat 200 and reduce the difficulty of fitting between the fitting seat 410 and the mounting seat 200.

[0066] Optionally, the slider 210 is integrally formed with the mounting seat 200. That is, the slider 210 and the mounting seat 200 are formed as an integral piece to reduce the difficulty of molding the slider 210, while also ensuring the connection quality between the slider 210 and the mounting seat 200, so that the slider 210 can be stably arranged on the mounting seat 200, ensuring the structural stability of the slider 210, thereby ensuring the connection quality between the mating seat 410 and the mounting seat 200.

[0067] Of course, in some other embodiments, a slider 210 may be provided on the inner wall of the avoidance channel 411, and a slide groove 4111 may be provided on the outer wall of the enclosure, and the present application does not impose any specific limitation thereto.

[0068] Optionally, the slider 210 is made of an elastic member, so that when the mating seat 410 and the mounting seat 200 are slidably matched, the elastic restoring force of the slider 210 can form an interference fit between the mating seat 410 and the mounting seat 200 after the mating is completed, so as to ensure the connection strength between the mating seat 410 and the mounting seat 200, so that the mating seat 410 can be stably installed on the mounting seat 200, thereby ensuring the position stability of the nasal plug assembly 400 and improving the working performance of the nasal plug assembly 400.

[0069] In some embodiments, Figure 4 As shown, the two opposite side walls of the avoidance channel 411 are provided with slide grooves 4111. In this way, it is convenient to provide the slide blocks 210 on the two opposite side walls of the mounting seat 200 to increase the contact area between the mounting seat 200 and the matching seat 410, which can ensure the position stability of the nasal plug assembly 400 during the disassembly and assembly process, and can also ensure the position stability of the nasal plug assembly 400 after the assembly is completed, thereby ensuring the working performance of the nasal plug assembly 400.

[0070] In some embodiments, in combination Figure 2 and Figure 4 As shown, the slide groove 4111 extends from top to bottom to ensure the extension length of the slide groove 4111, thereby ensuring the contact area between the matching seat 410 and the mounting seat 200, ensuring the connection strength between the matching seat 410 and the mounting seat 200, and thereby ensuring the structural stability of the matching seat 410.

[0071] Through the above arrangement, in a specific example, when the nasal plug assembly 400 needs to be replaced, the nasal plug assembly 400 on the mounting base 200 can be first removed from top to bottom along the extension direction of the slide groove 4111, and then the nasal plug assembly 400 to be used can be replaced from bottom to top along the extension direction of the slide groove 4111 for use by the patient.

[0072] In some embodiments, the inner wall of the avoidance channel 411 and the enclosure are stop-fitted, and a seal (not shown in the figure) is provided between the inner wall of the avoidance channel 411 and the enclosure. The seal is used to increase the sealing effect between the inner wall of the avoidance channel 411 and the enclosure, that is, to increase the sealing effect between the matching seat 410 and the mounting seat 200, to a certain extent, to prevent the oxygen from flowing out from between the matching seat 410 and the mounting seat 200 when the oxygen delivery mask 1000 is supplying oxygen, thereby ensuring the oxygen supply effect of the oxygen delivery mask 1000, which is beneficial to the patient's rehabilitation treatment.

[0073] In some embodiments, the seal is connected to the inner wall of the avoidance channel 411. In this way, after the mating seat 410 is mated and connected with the mounting seat 200, the seal can be arranged between the inner wall of the avoidance channel 411 and the enclosure to reduce the difficulty of mating the seal with the mating seat 410 and the mounting seat 200, thereby facilitating the sealing mating of the mating seat 410 and the mounting seat 200.

[0074] In some embodiments, the sealing member is a rubber member, and the rubber member is bonded and fixed to the inner wall of the avoidance channel 411. This allows the sealing member to be connected to the inner wall of the avoidance channel 411, and at the same time, the connection effect between the sealing member and the inner wall of the avoidance channel 411 is ensured, and the position stability of the sealing member is ensured, thereby ensuring the sealing effect between the mating seat 410 and the mounting seat 200.

[0075] At the same time, by configuring the sealing member to be a rubber member, the working performance of the sealing member can also be guaranteed, so as to ensure that the sealing member can effectively realize the sealing cooperation between the matching seat 410 and the mounting seat 200.

[0076] In some embodiments, the enclosure is integrally formed with the mask body 100. That is, the mounting seat 200 and the mask body 100 are formed as an integral piece to reduce the difficulty of molding the mounting seat 200, while also ensuring the connection quality between the mounting seat 200 and the mask body 100, so that the mounting seat 200 can be stably arranged on the mask body 100, improving the position stability of the mounting seat 200, thereby facilitating the use of the mounting seat 200 to support the mating seat 410 to ensure the working performance of the nasal plug assembly 400.

[0077] Of course, in some other embodiments, the enclosure may also be arranged on the mask body 100 by means of welding, bonding or bolting, and the present application does not impose any specific restrictions, as long as it is ensured that the mounting seat 200 can be stably arranged on the mask body 100.

[0078] In some embodiments, Figure 1 As shown, the oxygen delivery mask 1000 further includes a second oxygen delivery tube 300, which is disposed on the outside of the mask body 100 and connected to the oxygen delivery port 110. That is, the second oxygen delivery tube 300 is disposed on the side of the mask body 100 that is away from the patient's face, so as to avoid the second oxygen delivery tube 300 obstructing the use of the mask body 100, and at the same time, it is convenient to realize the connection between the second oxygen delivery tube 300 and the external high-flow oxygen machine, so that when the second oxygen delivery tube 300 is connected to the oxygen delivery port 110, the second oxygen delivery tube 300 can be used to deliver oxygen toward the oxygen delivery port 110, and then the oxygen delivery port 110 can be used to deliver oxygen toward the patient, so as to achieve the purpose of nasal high-flow oxygen therapy for the patient.

[0079] In the description of the present utility model, features defined as “first” or “second” may explicitly or implicitly include one or more such features, and are used to distinguish and describe the features, without any distinction in order or importance.

[0080] In some embodiments, one end of the second oxygen delivery tube 300 is connected to the oxygen delivery port 110, and the other end of the second oxygen delivery tube 300 is connected to the high-flow oxygen machine to achieve the connection between the oxygen delivery port 110 and the high-flow oxygen machine, thereby facilitating the use of the second oxygen delivery tube 300 to transport oxygen toward the oxygen delivery port 110, ensuring that the patient can receive nasal high-flow oxygen therapy using the oxygen delivery mask 1000.

[0081] In some embodiments, Figure 1As shown, the oxygen delivery mask 1000 further includes a rigid connecting tube 500, one end of which is fixedly connected to the mask body 100 and communicated with the oxygen delivery port 110, and the other end of the rigid connecting tube 500 is connected to the second oxygen delivery tube 300, so as to realize the communication between the second oxygen delivery tube 300 and the oxygen delivery port 110 and reduce the difficulty of the communication between the second oxygen delivery tube 300 and the oxygen delivery port 110, thereby facilitating the use of the second oxygen delivery tube 300 to transport oxygen toward the oxygen delivery port 110, and ensuring that the oxygen delivery mask 1000 can be used to perform nasal high-flow oxygen therapy on the patient.

[0082] Among them, the rigid connecting tube 500 and the mask body 100 can be connected by welding, bonding or one-piece molding process to achieve a fixed connection between the rigid connecting tube 500 and the mask body 100, and ensure the connection strength between the rigid connecting tube 500 and the mask body 100, so as to facilitate the use of the rigid connecting tube 500 to achieve the connection between the second oxygen delivery tube 300 and the oxygen delivery port 110.

[0083] Optionally, the second oxygen delivery tube 300 is detachably connected to the other end of the rigid connecting tube 500, which reduces the difficulty of assembling the second oxygen delivery tube 300 and facilitates the replacement of the second oxygen delivery tube 300.

[0084] In some embodiments, an inner wall of the other end of the rigid connecting tube 500 is provided with an internal thread, and an outer wall of the second oxygen delivery tube 300 is provided with an external thread matching the internal thread, and the external thread and the internal thread are matched and connected, thereby realizing a detachable connection between the second oxygen delivery tube 300 and the rigid connecting tube 500, reducing the difficulty of assembling the second oxygen delivery tube 300, and thus reducing the difficulty of connecting the second oxygen delivery tube 300 with the oxygen delivery port 110.
