Description

Technical Field

[0001] This utility model relates to the field of nasal cannula technology, and in particular to an oxygen inhalation nasal cannula. Background Technology

[0002] Oxygen therapy is an important medical technique with widespread medical applications. It involves administering oxygen to patients at a concentration higher than that in the air to increase the partial pressure of oxygen in their arterial blood and oxygen saturation, thereby promoting metabolism, maintaining vital bodily functions, and ultimately improving tissue hypoxia.

[0003] Disposable nasal cannulas are commonly used during oxygen therapy.

[0004] A nasal cannula is a small, flexible tube. It contains two open tips; one end connects to an oxygen source, and the other end connects to the patient's nose. This tube delivers a continuous supply of oxygen, helping to improve symptoms of oxygen deficiency.

[0005] The prior art disclosure number CN221384783U describes an extension tube for nasal cannula oxygen inhalation, including an elastic frame and an extension tube. The elastic frame has a limiting hole, the extension tube passes through the limiting hole, and an oxygen delivery tube is connected to the top of the extension tube. There are two extension tubes, and a fixing device is provided on the two extension tubes. The two extension tubes are connected at the bottom, and a nasal cannula is provided at the connection point of the two extension tubes. The nasal cannula is provided with two oxygen inhalation heads.

[0006] The fixation method used in this nasal cannula has the advantages of not damaging the skin or the back of the ear.

[0007] However, existing nasal cannulas are disposable, and the elastic frame and fixing device on the nasal cannulas are all integrated into the nasal cannulas and cannot be removed. Even if they are forcibly removed, they cannot be used on another nasal cannulas, causing them to be discarded along with the nasal cannulas and cannot be reused, thus causing a waste of resources. Therefore, an improvement is proposed. Utility Model Content

[0008] This invention is a nasal cannula for oxygen inhalation, proposed to address the shortcomings of existing technologies.

[0009] To achieve the above objectives, the present invention adopts the following technical solution: an oxygen inhalation nasal cannula, comprising a nasal cannula body, wherein the outer surface of the nasal cannula body is provided with an elastic frame and a shell;

[0010] Both sides of the outer surface of the elastic frame are fixedly connected to mounting seats, and one side of the outer surface of each of the two mounting seats is fixedly connected to a first fixed catheter seat. Both mounting seats are equipped with elastic push-pull components, and the movable ends of the two elastic push-pull components are fixedly connected to a first catheter pressure seat. The nasal cannula body is located between the first fixed catheter seat and the first catheter pressure seat.

[0011] Two second fixed catheter seats are symmetrically fixed to one side of the outer surface of the housing. The housing is equipped with a bidirectional elastic moving component. The two movable ends of the bidirectional elastic moving component are fixedly connected to the second catheter pressure seat, and the nasal catheter body is located between the second fixed catheter seat and the second catheter pressure seat.

[0012] Furthermore, both of the elastic push-pull components include a slide rod, which passes through the mounting base and is slidably connected thereto. The slide rod is fixedly connected to the adjacent first guide pressure seat. A mounting groove is provided on one side of the outer surface of the slide rod. A first spring is fixedly connected to the inner wall of one side of the mounting groove. A fixing block is fixedly connected to the other end of the first spring, and the fixing block is fixedly connected to the mounting base. The first spring and the fixing block cooperate to keep the slide rod in its original position when there is no external force.

[0013] Furthermore, a pressing plate is fixedly connected to one side of the outer surface of the slide rod, and the slide rod can be moved by pressing the pressing plate.

[0014] Furthermore, the bidirectional elastic moving component includes a travel groove, which is formed on one side of the outer surface of the housing. A second spring is provided on the inner side of the travel groove. Both ends of the second spring are fixedly connected to movable plates, and the movable plates are fixedly connected to the adjacent second guide pressure seat. The second spring has a pushing force on both movable plates, and in the absence of external force, it can push the two movable plates to always abut against the inner wall of the travel groove.

[0015] Furthermore, a pressing rod is fixedly connected to one side of the outer surface of each of the two movable plates, and the pressing rod extends through the inner wall of the stroke groove to the outer side of the housing. Pressing the two pressing rods at the same time can push the two movable plates closer to each other.

[0016] Furthermore, both movable plates slide against the inner walls of the travel groove on both sides, and the travel groove has a limiting effect on the movable plates, which can ensure the stability of the movement of the movable plates.

[0017] Furthermore, the two interfaces of the nasal cannula body are jointly connected to an oxygen delivery tube, which can be connected to an external oxygen supply device to provide oxygen for the use of the nasal cannula.

[0018] The beneficial effects of this utility model are:

[0019] In use, this utility model provides an oxygen inhalation nasal cannula with a separate design for the elastic frame, fixing device, and nasal cannula body, through the installation base, first fixing cannula base, first cannula pressure base, second fixing cannula base, second cannula pressure base, elastic push-pull component, and bidirectional elastic movement component. This design allows for easy separation of the elastic frame and fixing device, enabling reuse of the elastic frame and fixing device and avoiding resource waste. Furthermore, the position of the elastic frame on the nasal cannula body can be adjusted according to actual needs, thereby improving overall applicability. Attached Figure Description

The movable ends of the two elastic push-pull components are fixedly connected to a first catheter pressure seat 6. The nasal cannula body 1 is located between the first fixed catheter seat 2 and the first catheter pressure seat 6. Both elastic push-pull components include a slide rod 11. The slide rod 11 passes through the mounting base 7 and is slidably connected to it. The mounting base 7 has a limiting function for the slide rod 11, which can ensure its movement stability. The slide rod 11 is fixedly connected to the adjacent first catheter pressure seat 6. One side of the outer surface of the slide rod 11 is provided with a mounting groove 10. One side of the inner wall of the mounting groove 10 is fixedly connected to a first spring 9. The other end of the first spring 9 is fixedly connected to a fixing block 8. The fixing block 8 is fixedly connected to the mounting base 7. One side of the outer surface of the slide rod 11 is fixedly connected to a pressing plate 12. The pressing plate 12 is provided to increase the end area of ​​the slide rod 11, making it easier to manually push it to move.

[0029] Two second fixed catheter seats 13 are symmetrically fixed to one side of the outer surface of the housing 4. The housing 4 is equipped with a bidirectional elastic moving assembly. Two movable ends of the bidirectional elastic moving assembly are fixedly connected to second catheter pressing seats 17. Both the second fixed catheter seats 13 and the second catheter pressing seats 17 are provided with anti-slip textures on one side of the nasal cannula body 1 to increase friction and prevent slippage after pressing. The nasal cannula body 1 is located between the second fixed catheter seats 13 and the second catheter pressing seats 17. The bidirectional elastic moving assembly includes a travel groove 16, which is formed on one side of the outer surface of the housing 4. A second spring 15 is provided on the inner side of 16. Both ends of the second spring 15 are fixedly connected to movable plates 14, and the movable plates 14 are fixedly connected to the adjacent second guide pressure seat 17.

The pressing rod 18 is slidably connected to the housing 4, which can ensure the stability of the movement of the pressing rod 18. Both movable plates 14 slide against the inner walls of the two sides of the stroke groove 16. The stroke groove 16 limits the stroke of the movable plates 14 and can also ensure the stability of their movement.

[0030] The two interfaces of the nasal cannula body 1 are fixedly connected to the oxygen delivery tube 5. The function of the oxygen delivery tube 5 is to facilitate the connection between the nasal cannula body 1 and the external oxygen supply equipment pipeline.

[0031] Working principle: When the housing 4 and the elastic frame 3 need to be assembled onto the nasal cannula body 1, first assemble the housing 4, and simultaneously press the two pressing rods 18. The pressing rods 18 push the two movable plates 14 closer together, compressing the second spring 15. When the movable plates 14 move, they drive the second cannula pressing seat 17 away from the second fixed cannula seat 13 until the distance between the second cannula pressing seat 17 and the adjacent second fixed cannula seat 13 reaches the required distance. Then, place the nasal cannula body 1 between the second cannula pressing seat 17 and the second fixed cannula seat 13, and then release the pressing rods 18. The second spring 15 pushes... The movable plate 14 is reset, and the movable plate 14 drives the second catheter pressure seat 17 to reset until the nasal cannula body 1 is pressed. Then the elastic frame 3 is assembled, the pressing plate 12 is pressed, and the pressing plate 12 pushes the first catheter pressure seat 6 to move through the slide rod 11. The first catheter pressure seat 6 moves away from the first fixed catheter seat 2 until the desired position is reached. Then the nasal cannula body 1 is placed between the first catheter pressure seat 6 and the first fixed catheter seat 2. Then the pressing plate 12 is released, and the first spring 9 pushes the slide rod 11 to reset until the first catheter pressure seat 6 and the first fixed catheter seat 2 cooperate to complete the pressing and fixing of the nasal cannula body 1.
