Description

Technical Field

[0001] This utility model belongs to the field of medical device technology, specifically relating to a nasal cannula fixation clip. Background Technology

[0002] Intubation refers to the technique of inserting a catheter into the human body through openings or cavities on the surface or inside the body to deliver or remove gases or liquids. Gastric intubation and endotracheal intubation are usually inserted through the nasal cavity and secured with a fixator; therefore, these types of intubations can be collectively referred to as nasal intubation.

[0003] Currently, the commonly used methods for fixing nasal intubation tubes include elastic band traction and medical tape adhesion. Both methods have many drawbacks. For example, elastic bands are prone to falling off due to factors such as twisting and friction of the patient's head, and the tightness of the elastic band is not easy to control. If it is too tight, it will cause discomfort to the patient's head, and if it is too loose, it will increase the risk of falling off. On the other hand, if the adhesive is too sticky, it will cause great damage to the patient's skin, and if the adhesive is too weak, it will easily fall off. Therefore, there is an urgent need to optimize and improve the nasal intubation tube fixation methods in terms of reliability and comfort. Utility Model Content

[0004] This utility model provides a nasal cannula fixation clip, which aims to improve the reliability and comfort of nasal cannula fixation.

[0005] To achieve the above objectives, the present invention provides a nasal cannula fixing clip, comprising two single clips that are inserted into each other and form a sliding fit, and an adjustment buckle is provided between the two single clips to adjust and lock the relative sliding position of the two single clips; each of the two single clips is provided with a through hole aligned with one of the nostrils, the through hole being used to insert and clamp the cannula; clamp heads are provided on the side walls of the two single clips that are far apart from each other, the two clamp heads being used to clamp the two sides of the nose respectively.

[0006] In one possible implementation, the clamp includes an inner clamp arm and an outer clamp arm; wherein, the inner clamp arm is fixedly connected to the single clamp at the outer edge of the perforation, and the inner clamp arm extends along the axial direction of the perforation to extend into the nostril and fit against the inner wall of the nostril; the outer clamp arm is spaced apart from the inner clamp arm and hinged to the single clamp, the outer clamp arm is located on the outer side of the inner clamp arm away from the perforation, and the outer clamp arm is used to press against the outer surface of the nasal wing to cooperate with the inner clamp arm to clamp the nasal wing.

[0007] In some embodiments, the extended end of the inner clamping arm is provided with a magnetic sheet, and the side wall of the outer clamping arm facing the inner clamping arm is provided with a magnetic patch, the magnetic patch and the magnetic sheet are positioned corresponding to each other and attract each other.

[0008] For example, one of the clamps has a sliding hole, and the other clamp has a sliding rod. The sliding rod slides through the sliding hole, and an adjustment buckle is provided between the sliding rod and the sliding hole.

[0009] For example, the side wall of the slide bar is provided with a groove, and the adjusting buckle is a V-shaped spring. One end of the V-shaped spring is engaged in the groove, and the other end extends out of the groove to form a pressure handle. The V-shaped spring is provided with at least one wedge-shaped tooth, and the hole wall opposite to the groove is provided with a serrated strip suitable for engaging the wedge-shaped tooth.

[0010] For example, the bottom of the groove has recessed slots on both sides, and the V-shaped spring includes a locking section and a locking section that are connected to form a V shape; wherein, the two sides of the locking section are respectively engaged with the two slots, one end of the locking section is connected to the locking section, the other end extends out of the groove and forms a pressure handle, and the locking section is provided with at least one wedge-shaped tooth.

[0011] In some embodiments, the V-shaped spring sheet further includes an elastic arc plate, the elastic arc plate forming a pin hole at the contact position with the clamping section and the locking section, and a positioning pin is provided in the groove, the positioning pin passing through the pin hole.

[0012] In one possible implementation, a retaining sleeve is provided inside the perforation, which is used to fit the insertion tube and engage with the wall of the perforation.

[0013] For example, the perforation is a conical hole, and the small diameter end of the perforation is provided with a locking platform. The peripheral wall of the sleeve is a conical wall, and one end of the sleeve is provided with a protruding edge, while the other end is provided with a buckle that engages with the locking platform.

[0014] In some embodiments, the peripheral wall of the ferrule has multiple partition slits spaced apart circumferentially.

[0015] The beneficial effects of the nasal cannula fixing clip provided by this utility model are as follows: Compared with the prior art, the nasal cannula fixing clip of this utility model adopts two single clips that are slidably connected, which can adjust the distance between the clips on the two single clips. After adjustment, the two single clips are locked by adjusting buckles, thereby adapting to the wearing needs of people with different nasal wing widths. A single cannula can be selected to pass through and be fixed in the perforation on any single clip to enter the nostril. If two cannulas are needed, one cannula can be inserted into the perforation on each of the two single clips and the two cannulas can be inserted into one nostril respectively. This can meet the needs of using a single gastric tube or a single trachea, as well as the needs of using a gastric tube and a trachea for simultaneous intubation. By clamping the two clips on both sides of the nasal wings, it can not only avoid contact with the pillow and the influence of the patient's head twisting that could cause the cannula to fall off, thereby improving the fixation reliability, but also eliminates the need for fixation by other parts of the patient's body outside the nasal cavity. In particular, compared with the method of tightly clamping the patient's head with elastic bands and sticking medical tape to the patient's skin, it can greatly improve the comfort of the patient wearing the nasal cannula.

It should be understood that the terms "length," "width," "upper," "lower," "front," "rear," "top," "bottom," "inner," and "outer," etc., indicating orientation or positional relationships, are based on the orientation or positional relationships shown in the accompanying drawings and are used only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application. In the description of this application, "a plurality of" means two or more, unless otherwise explicitly specified.

[0026] Please refer to the following: Figures 1 to 7 The nasal cannula 30 fixing clip provided by this utility model will now be described. The nasal cannula 30 fixing clip includes two single clips 10 that are inserted into each other and form a sliding fit, and an adjustment buckle 20 is provided between the two single clips 10. The adjustment buckle 20 is used to adjust and lock the relative sliding position of the two single clips 10. Each of the two single clips 10 is provided with a through hole 11 aligned with one of the nostrils 80. The through hole 11 is used to pass through and clamp the cannula 30. Clamping heads 40 are provided on the side walls of the two single clips 10 that are far apart from each other. The two clamping heads 40 are used to clamp the two sides of the nostrils 60 respectively.

[0027] It should be explained that the structure of the human nose is as follows: Figure 7 As shown, the position between the two nostrils 80 is the columella 70, and the part of the two nostrils 80 away from the columella 70, or the position of the wall of the two nostrils 80 that is far apart from each other, is the nasal alar 60. In this embodiment, the clamps 40, which are respectively set at the side wall positions of the two single clamps 10 that are far apart from each other, clamp the two nasal alar 60 respectively, thereby reliably fixing the insertion tube 30 inserted in the perforation 11.

[0028] It should be noted that the aforementioned adjusting buckle 20 can be a conventional set screw locking structure, such as using a screw to tighten the sliding mating surfaces of the two single clamps 10 to achieve locking, and adjustment can be achieved by turning the screw; the adjusting buckle 20 can also be an elastic snap-fit ​​component, which can achieve sliding unlocking between the two single clamps 10 by releasing the snap-fit ​​relationship, and restore the snap-fit ​​relationship after adjustment to lock the relative position of the two single clamps 10; the aforementioned clamp 40 can be a component that elastically clamps the nose wing 60 based on an elastic element, or it can be a component that reliably clamps the nose wing 60 based on magnetic attraction.

[0029] The nasal cannula 30 fixing clip provided in this embodiment, compared with the prior art, uses two single clips 10 slidably connected to adjust the distance between the clip heads 40 on the two single clips 10. After adjustment, the two single clips 10 are locked by the adjusting buckle 20, thereby adapting to the wearing needs of people with different nasal wing widths 60. A single cannula 30 can be selectively passed through and fixed in the perforation 11 on any single clip 10 to enter the nostril 80. If two cannulas 30 are needed, one cannula 30 can be inserted into the perforation 11 on each of the two single clips 10, and the two cannulas 30 can be extended into the nostril 80 respectively. One of the nostrils 80 can meet the needs of using a single gastric tube or a single endotracheal tube, or the need to insert both a gastric tube and an endotracheal tube simultaneously 30. The two clamps 40 are respectively clamped at the two sides of the nostrils 60, which not only avoids contact with the pillow and prevents the tube 30 from falling off due to the twisting of the patient's head, thus improving the reliability of fixation, but also eliminates the need for fixation by other parts of the patient's body other than the nasal cavity. In particular, compared with the method of tightly binding the patient's head with elastic bands and attaching medical tape to the patient's skin, it can greatly improve the comfort of the patient wearing the nasal tube 30.

[0030] In some embodiments, see Figure 1 and Figure 7 The clamp 40 includes an inner clamp arm 41 and an outer clamp arm 42. The inner clamp arm 41 is fixedly connected to the single clamp 10 at the outer edge of the perforation 11. The inner clamp arm 41 extends along the axial direction of the perforation 11 to enter the nostril 80 and fit against the inner wall of the nostril 80. The outer clamp arm 42 is spaced apart from the inner clamp arm 41 and hinged to the single clamp 10. The outer clamp arm 42 is located on the outer side of the inner clamp arm 41 away from the perforation 11. The outer clamp arm 42 is used to press against the outer surface of the nasal wing 60 to cooperate with the inner clamp arm 41 to clamp the nasal wing 60.

[0031] Since the inner clamping arm 41 needs to extend into the nostril 80, it is fixedly connected to the single clamp 10. In order to meet the clamping requirements of the nasal wing 60, the outer clamping arm 42 is hinged to the single clamp 10. When in use, the inner clamping arm 41 is extended into the nostril 80, and the outer clamping arm 42 is outside the nostril 80. The clamping force between the inner clamping arm 41 and the outer clamping arm 42 is obtained through the elastic element or magnetic attraction element, thereby forming a stable state of clamping on the nasal wing 60. The structure is simple and compact, and it is convenient and comfortable to use.

[0032] It should be noted that you should refer to [link / reference]. Figure 3 and Figure 4The inner clamping arm 41 has a magnetic sheet 411 at its extended end, and the outer clamping arm 42 has a magnetic patch 421 on its sidewall facing the inner clamping arm 41. The magnetic patch 421 and the magnetic sheet 411 are positioned correspondingly and attract each other. Both the magnetic sheet 411 and the magnetic patch 421 can be thin sheets made of ferromagnetic medical metal materials. The magnetic patch 421 is magnetized to acquire magnetism. When the inner clamping arm 41 is inserted into the nostril 80, the outer clamping arm 42 is swung to attract the magnetic patch 421 and the magnetic sheet 411 across the nasal wing 60, thereby forming a reliable clamping of the nasal wing 60.

[0033] For a specific connection method between the two single clips 10 mentioned above, please refer to Figure 2 and Figure 4 One of the clips 10 has a sliding hole 12, and the other clip 10 has a sliding rod 13. The sliding rod 13 slides through the sliding hole 12, and an adjusting buckle 20 is provided between the sliding rod 13 and the sliding hole 12. The cross-sections of the sliding rod 13 and the sliding hole 12 can be rectangular, square, or other non-circular structures of corresponding sizes. The sliding connection between the two clips 10 is achieved by the sliding rod 13 passing through the sliding hole 12. The structure is simple, compact, and highly stable.

[0034] For some possible implementations, please refer to [link / reference]. Figure 2 and Figure 4 The slide bar 13 has a groove 131 on its side wall. The adjusting buckle 20 is a V-shaped spring. One end of the V-shaped spring is engaged in the groove 131, and the other end extends out of the groove 131 to form a pressure handle 21. The V-shaped spring has at least one wedge-shaped tooth 231. The sliding hole 12 has a serrated retaining strip 121 on its wall opposite to the groove 131, which is suitable for engaging the wedge-shaped tooth 231. When it is necessary to adjust the two single clips 10, pressing the pressure handle 21 of the V-shaped spring will separate the wedge-shaped tooth 231 from the serrated retaining strip 121, thereby unlocking. After adjustment, releasing the pressure handle 21 will cause the V-shaped spring to spring back, so that the wedge-shaped tooth 231 re-engages with the corresponding position of the serrated retaining strip 121, thereby locking. The structure is simple and compact, and the operation is convenient.

[0035] In some embodiments, such as Figure 5 and Figure 6 As shown, the bottom of the groove 131 has recessed slots 1311 on both sides. The V-shaped spring includes a locking section 22 and a locking section 23 that are connected to form a V shape. The two sides of the locking section 22 are respectively engaged with the two slots 1311. One end of the locking section 23 is connected to the locking section 22, and the other end extends out of the groove 131 to form a pressure handle 21. The locking section 23 is provided with at least one wedge-shaped tooth 231.

[0036] Inserting the mounting section 22 into the slot 1311 creates a constraint on the mounting section 22, thereby ensuring reliable connection. On this basis, the locking section 23 elastically presses upward against the wall of the sliding hole 12, thereby making the wedge tooth 231 reliably engaged with the serrated locking strip 121, which is convenient to unlock and has a stable and reliable locking state.

[0037] To further improve connection reliability, please refer to Figure 2 and Figure 6 The V-shaped spring also includes an elastic arc plate 24. The contact position between the elastic arc plate 24 and the locking section 22 and the locking section 23 forms a pin hole 241. A positioning pin 1312 is provided in the groove 131, and the positioning pin 1312 passes through the pin hole 241. The positioning pin 1312 and the pin hole 241 are interlocked to constrain the V-shaped spring in the extension direction of the groove 131, thereby preventing the V-shaped spring from coming out of the groove 131 and causing locking failure, thus improving the locking stability between the two single clips 10.

[0038] For some possible implementations, please refer to [link / reference]. Figure 1 A retaining sleeve 50 is provided inside the perforation 11. The retaining sleeve 50 is used to fit the insertion tube 30 and engage with the wall of the perforation 11. By setting the retaining sleeve 50 to tighten the insertion tube 30, and by utilizing the engagement between the retaining sleeve 50 and the perforation 11, axial sliding misalignment of the insertion tube 30 within the perforation 11 is prevented, thereby improving the reliability of fixing the insertion tube 30.

[0039] Specifically, please refer to Figures 2 to 4 In this embodiment, the perforation 11 is a conical hole, and a retaining plate 111 is provided at the small-diameter end of the perforation 11. The peripheral wall of the retaining sleeve 50 is a conical wall, and one end of the retaining sleeve 50 is provided with a protruding edge 51, and the other end is provided with a buckle 52, which engages with the retaining plate 111. By utilizing the fit between the conical hole and the conical wall, the retaining sleeve 50 can exert radial pressure on the insertion tube 30 and clamp the insertion tube 30 during the insertion of the retaining sleeve 50 into the perforation 11. At the same time, the protruding edge 51 and the buckle 52 act on the two ends of the perforation 11 respectively to constrain the axial position of the retaining sleeve 50, thereby ensuring the reliability of the fixation of the insertion tube 30.

[0040] It should be noted that, see Figure 4 In this embodiment, the ferrule 50 has multiple partition slits 53 spaced apart along its circumferential direction on its peripheral wall. By setting the partition slits 53, the ferrule 50 can be compressed and clamped to the insertion tube 30 under the continuous squeezing action of the conical wall during the insertion of the ferrule 50 into the perforation 11, thereby improving the fixation reliability of the insertion tube 30.

[0041] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
