[0026] See also Figure 1-4 In a first aspect, the present application provides a nasal oxygen tube 3 fixing structure for fixing the nasal oxygen tube 3 to the face, the fixing structure comprising: an adhesive member 1 and a connecting structure 2; the adhesive member 1 has a first surface 11 and a second surface that are relatively arranged in the thickness direction, the connecting structure 2 is arranged on the first surface 11, the nasal plug 31 is detachably connected to the connecting structure 2, and the second surface is used for sticking to the face.
[0027] The fixing structure of the utility model includes an adhesive member 1 and a connecting structure 2. The adhesive member 1 has a first surface 11 and a second surface. The connecting structure 2 is arranged on the first surface 11, and the nose plug 31 of the nasal oxygen tube 3 is detachably connected to the connecting structure 2. Therefore, when the nose plug 31 is fixed to the connecting structure 2, the nasal oxygen tube 3 is relatively fixed to the first surface 11, and the nasal oxygen tube 3 is fixed to the adhesive member 1. Since the second surface of the adhesive member 1 can be attached to the face, the adhesive member 1 can increase the contact area between the nasal oxygen tube 3 and the face, so that the nasal oxygen tube 3 can be better fitted to the face.
[0028] For further information, see Figure 1In some embodiments, the connection structure 2 includes a limiting annular structure 21, the axial direction of the limiting annular structure 21 is parallel to the first surface 11, and the outer side of the nose plug 31 is interference fit with the inner side of the limiting annular structure 21. Specifically, the nose plug 31 and the limiting annular structure 21 are both made of soft and elastic plastic material, and the outer side of the nose plug 31 and the inner side of the limiting annular structure 21 are interference fit, so that the nose plug 31 can be stably assembled in the limiting annular structure 21, and then the nasal oxygen tube 3 can be stably connected with the adhesive member 1, so that the adhesive member 1 can be used to expand the contact area between the nasal oxygen tube 3 and the face.
[0029] For further information, see Figure 2-4 In some embodiments, the connection structure 2 includes a first main body portion disposed on the first surface 11, and a limiting structure disposed on the first main body portion, and the limiting structure is used to fix the nasal plug 31 to the first main body portion. Through the limiting effect of the limiting structure, the nasal plug 31 can be stably fixed to the first main body portion of the connection structure 2, and the connection structure 2 is disposed on the first surface 11 of the adhesive member 1, so that the nasal plug 31 of the nasal oxygen tube 3 can be relatively fixed to the first surface 11, and then the nasal oxygen tube 3 can be stably assembled on the adhesive member 1, so that the adhesive member 1 can be used to expand the contact area between the nasal oxygen tube 3 and the face.
[0030] For further information, see Figure 2 and Figure 4 In some embodiments, the first main body portion includes an annular structure 22 whose axial direction is parallel to the first surface 11, and the nose plug 31 is inserted into the annular structure 22; the limiting structure includes a first through hole 221 opened on the annular structure 22, and the nose plug 31 is provided with a first protrusion 311, and the first protrusion 311 is embedded in the first through hole 221.
[0031] Specifically, the inner diameter of the annular structure 22 is slightly larger than or equal to the outer diameter of the nose plug 31, that is, when the nose plug 31 is assembled in the annular structure 22, the two are not in an interference fit relationship, but the outer side of the nose plug 31 can just abut against the inner side of the annular structure 22. On the one hand, the nose plug 31 can be inserted into the annular structure 22 relatively easily, and on the other hand, the annular structure 22 can limit the radial movement of the nose plug 31. In addition, the number of the first through hole 221 and the first protrusion 311 is not specifically limited, and can be one, two, three, four, or five, etc., and the position of the first through hole 221 in the annular structure 22 and the position of the first protrusion 311 in the nasal cannula are not specifically limited. It is only necessary to ensure that when the nose plug 31 is inserted into the annular structure 22, the first through hole 221 and the first protrusion 311 can correspond one to one. When the nose plug 31 is inserted into the annular structure 22, the first protrusion 311 is correspondingly embedded in the first through hole 221. Through the cooperation between the first protrusion 311 and the first through hole 221, the axial movement and circumferential rotation of the nose plug 31 can be limited. Therefore, through the above structure, the nose plug 31 can be stably assembled to the connection structure 2, and the nasal oxygen tube 3 and the first surface 11 can be relatively fixed, so that the nasal oxygen tube 3 can be fixed to the adhesive 1. In other possible implementations, the first protrusion 311 can be set on the inner wall of the annular structure 22, and the first through hole 221 can be set on the nose plug 31. In this case, the fixing structure also includes a sealing member, and the first protrusion 311 is embedded in the first through hole 221 through the sealing member, so as to achieve a sealed connection between the first protrusion 311 and the first through hole 221, and the nose plug 31 can also be stably assembled to the connection structure 2. However, compared with the solution in which the first through hole 221 is provided in the nasal plug 31, in the solution in which the first through hole 221 is provided in the annular structure 22, the sealing performance of the nasal oxygen tube 3 is higher, and no sealing part is required, which simplifies the structure and reduces the cost. Therefore, the solution in which the first through hole 221 is provided in the annular structure 22 is preferred.
[0032] In some other embodiments, the first main body portion includes two split portions that are arranged on the first surface 11 and are opposite to each other, and the two sides of the nose plug 31 are respectively abutted against the two split portions; the limiting structure includes a second through hole opened on the split portion, and the nose plug 31 is provided with a second protrusion, which is embedded in the second through hole.
[0033] Specifically, the two split parts are arranged at intervals, and the minimum vertical spacing between the two split parts is slightly greater than or equal to the outer diameter of the nose plug 31. On the one hand, the nose plug 31 can be inserted between the two split parts relatively easily. On the other hand, the two sides of the nose plug 31 are respectively abutted against the two split parts, so that the two split parts can limit the radial movement of the nose plug 31. In addition, the number of the second through hole and the second protrusion is not specifically limited, and can be one, two, three, four, or five, etc., and the position of the second through hole in one of the split parts, the position of the second through hole in the other split part, and the position of the second protrusion in the nasal cannula are not specifically limited. It is only necessary to ensure that when the nose plug 31 is inserted between the two split parts, the second through hole and the second protrusion can correspond one to one. When the nose plug 31 is inserted between the two split parts, the second protrusion is correspondingly embedded in the second through hole. Through the cooperation of the second protrusion and the second through hole, the axial movement and circumferential rotation of the nose plug 31 can be limited. Therefore, through the above structure, the nose plug 31 can be stably assembled to the connection structure 2, and the nasal oxygen tube 3 and the first surface 11 can be relatively fixed, so that the nasal oxygen tube 3 can be fixed to the adhesive member 1. Similarly, in other possible implementations, the second protrusion can be set on the opposite sides of the two split parts, and the second through hole can be set on the nose plug 31. In this case, the fixing structure also includes a sealing member, and the second protrusion is embedded in the second through hole through the sealing member, so as to achieve a sealed connection between the second protrusion and the second through hole, and the nose plug 31 can also be stably assembled to the connection structure 2, but the solution in which the second through hole is set on the split part is preferred.
[0034] Furthermore, in some embodiments, arc structures are provided on opposite sides of the two split parts, and the two sides of the nose plug 31 are respectively in contact with the arc structures. Since the nose plug 31 is a cylindrical structure, by providing an arc structure on the opposite sides of the split parts, when the nose plug 31 is inserted between the two split parts, the outer side of the nose plug 31 is in contact with the arc structure of the split parts, which can increase the contact area between the nose plug 31 and the two split parts, thereby increasing the abutment force of the split parts on the nose plug 31, and further limiting the radial movement of the nose plug 31.
[0035] For further information, see Figure 3In some embodiments, the connection structure 2 includes a second main body 23 and a connection part 24, the connection part 24 is disposed on the first surface 11, a connection hole 241 is opened on the side of the connection part 24 facing the second main body 23, one end of the second main body 23 is disposed on the first surface 11 and the other end is penetrated through the connection hole 241, an assembly hole 25 is formed between the second main body 23, the connection part 24 and the first surface 11, the second main body 23 can be slidably connected to the connection hole 241 to change the area of the assembly hole 25, and the nose plug 31 can be fixed to the assembly hole 25. After the nose plug 31 is inserted into the assembly hole 25, since the second main body 23 can be slidably connected to the connection hole 241, the second main body 23 can be pulled so that the diameter of the assembly hole 25 is equal to or slightly smaller than the outer diameter of the nose plug 31, that is, the outer side of the nose plug 31 is interference-fitted with the inner wall of the assembly hole 25, so that the nose plug 31 can be stably assembled in the assembly hole 25.
[0036] For further information, see Figure 3 In some embodiments, a Velcro 26 is provided on the side of the second main body 23 away from the assembly hole 25, and one end of the second main body 23 passing through the connection hole 241 can be bent toward the side away from the second surface and move toward the other end, and the Velcro 26 at one end of the second main body 23 can fit the Velcro 26 at the other end to fix the nose plug 31. After the second main body 23 is pulled and the diameter of the assembly hole 25 is adjusted so that the outer side of the nose plug 31 is interference-fitted with the inner wall of the assembly hole 25, it is necessary to bend one end of the second main body 23 passing through the connection hole 241 so that it is wrapped back to the other end. Since the side of the second main body 23 away from the assembly hole 25 is provided with a Velcro 26, when the second main body 23 passes through one end of the connection hole 241 and goes back to the other end, the Velcro 26 at both ends are just opposite to each other, and the Velcro 26 at both ends are attached, so that the second main body 23 can no longer be pulled (unless the Velcro 26 at both ends are considered to be separated), so that the size of the assembly hole 25 can no longer be changed, so that the nose plug 31 can be stably assembled in the assembly hole 25. In some other embodiments, the fixing structure may include a clamping member, which is provided on the side of the connecting member away from the assembly hole 25, and the clamping member can clamp one end of the second main body 23 passing through the connection hole 241. When the second main body 23 is pulled to a suitable position, the clamping member clamps one end of the second main body 23 passing through the connection hole 241, so that the second main body 23 can no longer be pulled.
[0037] For further information, see Figure 1-4The adhesive member 1 includes a fixing sheet, a first connecting layer coated on the fixing sheet, and a second connecting layer coated on the first connecting layer away from the fixing sheet. The first surface 11 is arranged on the side of the fixing sheet away from the first connecting layer, and the second surface is arranged on the side of the second connecting layer away from the first connecting layer. The first connecting layer is foam, and the second connecting layer is silicone gel. Specifically, the fixing sheet is made of silicone injection molding, one of the surfaces of the fixing sheet is the first surface 11, and the connecting structure 2 arranged on the first surface 11 can be integrally injection molded with the fixing sheet, or can be separately connected. The connecting structure 2 can fix the nasal oxygen tube 3 to the fixing sheet, and can also support the nasal oxygen tube 3. The first connecting layer is foamed cotton, which is coated on the side of the fixing sheet away from the connecting structure 2, and can play a role in ventilation, cushioning and support. The second connecting layer is silicone gel, which is coated on the foam cotton and applied to the skin to play a connecting role. Due to the characteristics of silicone gel, the adhesive piece 1 has excellent air permeability and a long continuous adhesion time. Due to the effect of the foam cotton, the entire weight of the nasal oxygen tube 3 is pressed on the foam, which can reduce the pressure of the buffer nasal oxygen tube 3 on the skin.
[0038] See also Figure 4 In a second aspect, the present application provides a nasal oxygen tube 3, comprising a fixing structure as described in any of the above embodiments. Both sides of the nasal oxygen tube 3 are nasal plugs 31, and one nasal oxygen tube 3 may include two fixing structures, that is, one nasal oxygen tube 3 includes two adhesive members 1 and two connecting structures 2 corresponding to the adhesive members 1. Through the connecting structure 2, the nasal plug 31 of the nasal oxygen tube 3 is stably assembled on the adhesive member 1, and the adhesive member 1 can increase the contact area between the nasal oxygen tube 3 and the face, so that the nasal oxygen tube 3 can better fit the face.
[0039] In the above embodiments, the description of each embodiment has its own emphasis. For parts that are not described in detail in a certain embodiment, reference can be made to the relevant descriptions of other embodiments.
[0040] The above is a description of the technical solution provided by the utility model.
