Description

Technical Field

[0001] This invention relates to the field of medical device technology, specifically to a nasal plug and an oxygen delivery assembly. Background Technology

[0002] The existing oxygen tube nasal plug includes a nasal plug body and a nasal fork outlet for inserting into the nostril. The nasal plug body has a nasal plug body plane for facing the nostril, and the nasal fork outlet is formed on the nasal plug body plane.

[0003] During use, the nasal cannula outlet is inserted into the nostril. To secure the nasal cannula well, it is usually moved upward relative to the nose so that the main body of the nasal cannula fits against the edge of the nostril. This allows the nasal cannula outlet to extend deeper into the nostril to provide oxygen to the user.

[0004] However, in actual use, the current oxygen tube nasal plugs often cause users, especially those with weaker breathing abilities, to experience difficulty exhaling and shortness of breath. Summary of the Invention

[0005] The purpose of this invention is to solve the problem that existing oxygen tube nasal plugs cause users to have difficulty exhaling and shortness of breath in actual use, so as to improve the user's breathing smoothness when using nasal plugs.

[0006] Therefore, the present invention provides a nasal plug, which includes a nasal plug body for being located outside the nostril and an air outlet tube disposed on the nasal plug body for being inserted into the nostril, wherein the nasal plug body is provided with a stop structure for abutting against the face of the nasal plug wearer so as to maintain an air outlet gap between the edge of the nostril and the nasal plug body.

[0007] In this technical solution, the nasal plug body is equipped with a stop structure that rests against the face of the nasal plug wearer to maintain an exhaust gap between the edge of the nostrils and the nasal plug body. In actual use, when the air tube is inserted into the nasal plug wearer's nostrils, the stop structure can rest against the face of the nasal plug wearer to maintain an exhaust gap between the edge of the nostrils and the nasal plug body. Thus, even if the nasal plug body rests against the edge of the nostrils, the air exhaled by the nasal plug wearer can be quickly expelled through the exhaust gap due to the existence of the exhaust gap, thereby avoiding the problem of difficulty in exhaling or shortness of breath for the nasal plug wearer, and improving the smoothness and comfort of breathing when using the nasal plug.

[0008] Furthermore, the stop structure is configured to abut against the edge of the nostril.

[0009] Furthermore, the stop structure itself has an exhaust structure for communicating with the nostrils.

[0010] Furthermore, the nasal plug body includes a nasal plug body plane for facing the nostrils, and the air outlet tube and the stop structure are both disposed on the nasal plug body plane.

[0011] Furthermore, the nasal plug body plane serves as the stop structure, wherein an exhaust groove for communicating with the nostril is formed on the nasal plug body plane as the exhaust interval.

[0012] Alternatively, the stop structure may include a stop protrusion.

[0013] Furthermore, the stop protrusion is located on the plane of the nasal plug body at a position corresponding to the nasal septum between the two nostrils.

[0014] Furthermore, the two sides of the surface of the stop protrusion facing the nostril are respectively formed as inclined surfaces extending obliquely to both sides along the width direction of the nose, and the inclined surfaces are used to form an exhaust gap with the nostril, and the exhaust structure includes the exhaust gap.

[0015] Furthermore, at least a portion of the surface of the stop protrusion facing the nostril is formed as an outwardly convex arcuate surface for extending along the height direction of the nose.

[0016] Furthermore, the stop protrusion is used to form an exhaust groove on the surface corresponding to the nasal septum, which extends through the nose along the height direction.

[0017] Alternatively, the stop protrusions may be present at both ends of the plane of the nasal plug body.

[0018] Furthermore, the stop protrusion is a curved protrusion with an outwardly oriented opening, the curved protrusion forming an exhaust space with the opening on the plane of the nose plug body, and the exhaust structure includes the exhaust space.

[0019] Furthermore, the height of the curved protrusion is designed to gradually decrease outward in the width direction of the nose.

[0020] Finally, the present invention provides an oxygen delivery assembly comprising an oxygen delivery tube and any of the above-described nasal plugs, wherein the oxygen delivery tube is connected to the nasal plug body and is capable of communicating with the air outlet tube.

[0031] It should be noted that, unless otherwise specified, the embodiments and features described in this invention can be combined with each other. The invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0032] refer to Figure 1 and Figure 4 as well as Figure 5 and Figure 8 The nasal plug provided by the present invention includes a nasal plug body 1 for being located outside the nostrils of the nose 13 and an air outlet tube 2 disposed on the nasal plug body 1 for being inserted into the nostrils. The nasal plug body 1 is provided with a stop structure for abutting against the face of the nasal plug wearer so that an exhaust interval 3 is maintained between the edge of the nostrils and the nasal plug body 1.

[0033] In this nasal plug, the nasal plug body 1 is provided with a stop structure for abutting against the face of the nasal plug wearer to maintain an exhaust gap 3 between the edge of the nostril and the nasal plug body 1. Thus, in actual use, when the air tube 2 is inserted into the nostril of the nasal plug wearer's nose 13, the stop structure can abut against the face of the nasal plug wearer to maintain an exhaust gap between the edge of the nostril and the nasal plug body 1. In this way, even if the nasal plug body 1 abuts against the edge of the nostril, the air exhaled by the nasal plug wearer can be quickly discharged through the exhaust gap 3 due to the existence of the exhaust gap 3, thereby avoiding the problem of difficulty in exhaling or shortness of breath for the nasal plug wearer, and improving the smoothness and comfort of breathing when using the nasal plug.

[0034] It should be noted that in the nasal plug of the present invention, the stop structure can abut against the face of the nasal plug wearer, for example, it can abut against the area of ​​the face around the nose, or it can abut against the outer surface of the nose, or it can abut against the edge of the nostrils. Therefore, regardless of where the stop structure abuts against the face, the stop structure only needs to maintain an air venting gap 3 between the edge of the nostrils and the nasal plug body 1.

[0035] For example, in one embodiment, reference Figure 3 and Figure 4 The stop structure is designed to rest against the edge of the nostril. In this way, the nasal plug can be used to rest against the stop structure by utilizing the continuous, nearly straight edge of the nostril, making it convenient and comfortable to use.

[0036] In addition, such as Figure 4 As shown, after the stop structure abuts against the edge of the nostril, an exhaust gap 3 is maintained between the nasal plug body 1 and the edge of the nostril. At this time, the stop structure itself can form an exhaust structure for communicating with the nostril. In this way, while exhaled air is discharged through the exhaust gap 3, part of the exhaled air can be discharged through the exhaust structure of the stop structure, thereby further improving the smoothness of exhaust. Of course, optionally, the stop structure itself may not form such an exhaust structure, as long as the stop structure itself does not affect the exhaust of the nostril.

[0037] Furthermore, the stop structure can be formed at any position on the nasal plug body 1. For example, the stop structure can be located at a position on the nasal plug body 1 that is laterally away from the nostrils, or at a position on the nasal plug body 1 that is laterally close to the nostrils, or at a position on the nasal plug body 1 facing the nostrils. That is, regardless of the position of the stop structure on the nasal plug body 1, it only needs to be able to abut against the face, for example, against the edge of the nostrils, so that an exhaust gap 3 is maintained between the edge of the nostrils and the nasal plug body 1. Similarly, the air outlet tube 2 can be located at any position on the nasal plug body 1, as long as it can extend into the nostrils.

[0038] For example, refer to Figure 1 and Figure 2 The illustrated embodiments and Figure 5 and Figure 6 In the illustrated embodiment, the nasal plug body 1 includes a nasal plug body plane 4 facing the nostrils, an air outlet tube 2 disposed on the nasal plug body plane 4, and a stop structure disposed on the nasal plug body plane 4. That is, in actual use, the air outlet tube 2 on the nasal plug body plane 4 can be easily and directly inserted into the nostrils. At this time, the nasal plug body plane 4 directly faces the nostrils. Since the stop structure is disposed on the nasal plug body plane 4, the stop structure directly abuts against the edge of the nostrils, for example, as shown in the reference... Figure 3 and Figure 4 as well as Figure 7 and Figure 8 shown.

[0039] Since the plane 4 of the nasal plug body directly faces the nostrils, a stop structure can be easily formed on the plane 4 of the nasal plug body so that the stop structure can easily abut against the edge of the nostrils. This also makes the structure of the nasal plug simple and the molding cost low.

[0040] Furthermore, the stop structure provided on the nasal plug body plane 4 can have various structural types. However, it should be noted that regardless of the structural type of the stop structure, it is sufficient to maintain an exhaust interval 3 between the edge of the nostril and the nasal plug body 1. For example, in one type of stop structure, the nasal plug body plane 4 serves as the stop structure, wherein an exhaust groove for communicating with the nostril is formed on the nasal plug body plane 4 as an exhaust interval 3. That is, an exhaust groove is formed on the nasal plug body plane 4. In this way, during use, the nasal plug body plane 4 will abut against the edge of the nostril, and exhalation can be discharged through the exhaust groove.

[0041] Alternatively, in another type of stop structure, the stop structure includes a stop protrusion 5, that is, the stop protrusion 5 protrudes from the plane 4 of the nasal plug body. In this way, during use, the stop protrusion 5 will abut against the edge of the nostril so that the plane 4 of the nasal plug body does not abut against the edge of the nostril. In this way, the plane 4 of the nasal plug body and the edge of the nostril will maintain an exhaust gap 3.

[0042] Furthermore, the stop protrusion 5 can be formed at any position on the plane 4 of the nasal plug body, as long as it can abut against the edge of the nostril. For example, in one embodiment where the stop protrusion 5 is positioned, refer to... Figures 1-4As shown, the stop protrusion 5 is positioned on the nasal septum between the two nostrils on the nasal plug body plane 4. In actual use, the stop protrusion 5 will abut against the nasal septum between the two nostrils, preventing the nasal plug body plane 4 from abutting against the edges of the nostrils. This allows exhaled air to escape through the exhaust gap 3 between the nasal plug body plane 4 and the edges of the nostrils. Figure 4 As shown by the arrow in the image.

[0043] Additionally, there can be one or two air outlet pipes, for example, in... Figure 1 In the embodiment shown, there are two air outlet pipes 2 arranged at intervals, and the stop protrusion 5 is located between the two air outlet pipes 2.

[0044] Furthermore, as described above, the stop structure itself can be formed with an exhaust structure for communicating with the nostrils. Therefore, in another embodiment, the two sides of the surface of the stop protrusion 5 facing the nostrils are respectively formed as inclined surfaces 7 extending laterally along the width direction of the nose. These inclined surfaces 7 are used to form an exhaust gap 6 between the stop protrusion 5 and the nostrils. The exhaust structure includes the exhaust gap 6, such as... Figure 1-4 As shown, a portion of the air exhaled from each nostril can be discharged through the corresponding exhaust gap 6 on each side in the width direction. The inclined surface 7 can be a straight inclined surface, or it can be a convex arc-shaped surface extending in the width direction of the nose.

[0045] In another embodiment, at least a portion of the surface of the stop protrusion 5 facing the nostrils is formed as a convex arcuate surface 8 extending in the direction of nose height. For example, at least two sides of the surface of the stop protrusion 5 facing the nostrils are formed as convex arcuate surfaces 8 extending in the direction of nose height. Figure 1 As shown, the most protruding segment of the outwardly convex arc surface 8 can abut against the edge of the nostril, thereby forming arc-shaped guide portions on the upper and lower sides of the nostril to further guide a portion of the exhaled air to be quickly expelled along the arc surface, thus improving the smoothness of breathing. The aforementioned stop protrusion 5 can be set as one, two, or more.

[0046] In another embodiment, such as Figure 1 , Figure 2 and Figure 4 As shown, a venting groove 9 extending through the nose height direction is formed on the surface of the stop protrusion 5 corresponding to the nasal septum. For example, there may be one stop protrusion 5, and the venting groove 9 is formed on the surface of the one stop protrusion 5 facing the nasal septum; or, there may be two symmetrical stop protrusions 5 provided between two air outlet tubes 2, such as those of a nasal plug, with a venting groove 9 extending through the nose height direction formed on the surface between the two symmetrical stop protrusions 5 facing the nasal septum. Figure 2 and Figure 4 A portion of the air exhaled from both nostrils can converge into the exhaust groove 9, and then be discharged from the upper and lower sides along the height of the nose, thereby improving the smoothness of air exhalation.

[0047] For example, refer to Figures 5-8 In another embodiment of the positioning of the stop protrusion 5, there are stop protrusions 5 at both ends of the plane 4 of the nose plug body. In this way, during use, the stop protrusions 5 at both ends can abut against the edges of the two nostrils respectively, thereby improving the balance and stability of the nose plug when worn.

[0048] Furthermore, as mentioned above, the stop structure itself can be formed with an exhaust structure for communicating with the nostrils; therefore, in other embodiments, such as Figure 5 and Figure 6 As shown, the stop protrusion 5 is a curved protrusion 11 with an outwardly facing opening 10. The curved protrusion 11 can be a semi-circular protrusion, an arc-shaped protrusion, or other wavy protrusion. The curved protrusion 11 forms an exhaust space 12 with an opening 10 on the plane 4 of the nasal plug body. The exhaust structure includes the exhaust space 12. Thus, in use, the curved protrusion 11 abuts against the edge of the nostril. Since the exhaust space 12 has an opening 10, some of the air exhaled from the nostril can enter the exhaust space 12 and be discharged through the opening 10. Because the curved protrusion 11 can maintain an exhaust gap 3 between the plane 4 of the nasal plug body and the edge of the nostril, other air exhaled from the nostril can be directly discharged through the exhaust gap 3. Figure 6 and Figure 8 As shown by the arrow in the image.

[0049] In addition, such as Figure 5 , Figure 7 and Figure 8 As shown, the height of the curved protrusion 11 is designed to gradually decrease outward in the width direction of the nose; that is, in the width direction of the nose, the height of the curved protrusions 11 on both sides gradually decreases outward. Thus, as... Figure 8 As shown, an exhaust port with a larger size, including the opening 10, can be formed on the outside, which makes it easier for exhaled gas in the exhaust space 12 to be discharged, thus improving the smoothness of breathing.

[0050] Finally, the present invention provides an oxygen delivery assembly, which includes an oxygen delivery tube and any of the above-described nasal plugs, wherein the oxygen delivery tube is connected to the nasal plug body 1 and can communicate with the air outlet tube 2.

[0051] The preferred embodiments of the present invention have been described in detail above with reference to the accompanying drawings; however, the present invention is not limited thereto. Within the scope of the inventive concept, various simple modifications can be made to the technical solutions of the present invention. This includes combining various specific technical features in any suitable manner. To avoid unnecessary repetition, the present invention will not further describe the various possible combinations. However, these simple modifications and combinations should also be considered as part of the content disclosed in this invention and are all within the protection scope of this invention.
