Description

Technical Field

[0001] This utility model relates to a nasal oxygen tube, and more particularly to a nasal oxygen tube with a suspension structure, belonging to the field of nasal oxygen tube technology. Background Technology

[0002] In the medical field, nasal oxygen tubes are a very common medical device, widely used in hospital wards, home care, and other scenarios requiring oxygen therapy. For patients with breathing difficulties, poor cardiopulmonary function, and those requiring supplemental oxygen during postoperative recovery, nasal oxygen tubes are an important tool to ensure their oxygen supply and maintain normal physiological functions. However, most nasal oxygen tubes on the market are currently worn by wrapping them around behind the ear and suspending them at the upper part of the ear. In this way, the nasal oxygen tube is prone to falling off from the ear during use. During daily activities, such as turning over, sitting up, walking, or sleeping, even slight movements may cause the nasal oxygen tube to shift or even fall off. Once the nasal oxygen tube falls off, it will interrupt the oxygen supply, which will affect the patient's treatment effect.

[0003] Therefore, there is an urgent need to improve the nasal oxygen cannula with a suspension structure to solve the aforementioned problems. Utility Model Content

[0021] The following will describe in detail the implementation of this application with reference to the accompanying drawings and embodiments, so that the implementation process of how this application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0022] like Figures 1-5As shown in the figure, the nasal oxygen cannula with a suspension structure provided in this embodiment includes a clamp 1, an oxygen supply tube 2, and a nasal tube 3. Two mounting pieces 4 are fixedly connected to the outer surface of the clamp 1. The two mounting pieces 4 are symmetrically arranged. An adjustment component 5 is provided on the outer side of the mounting pieces 4. The adjustment component 5 includes a toothed sleeve 501 and a toothed plate 502. The toothed sleeve 501 is fixedly sleeved on the outer side of the oxygen supply tube 2. The outer side of the toothed sleeve 501 is provided with multiple first teeth 6. The toothed plate 502 is connected to the mounting piece 4 through a mounting groove 7. The bottom of the toothed plate 502 is provided with second teeth 8. The two oxygen supply tubes 2 are fixedly connected to both ends of the nasal tube 3. The adjustment component 5 is connected to a release component 9. The mounting groove 7 is fixedly connected to the outer side of the mounting piece 4. One end of plate 502 is rotatably connected to the inner wall of mounting groove 7 via rotating shaft 10. A torsion spring 11 is sleeved on the outer surface of rotating shaft 10. The two ends of torsion spring 11 are fixedly connected to mounting groove 7 and mounting piece 4, respectively. Release assembly 9 includes release piece 901 and sliding shaft 902. Support plate 14 is fixedly connected to the outer side of mounting piece 4. Release piece 901 is located between support plate 14 and mounting groove 7. Both sides of release piece 901 are rotatably connected to the outer side of mounting groove 7 and support plate 14. Sliding shaft 902 is fixedly connected to the end of toothed plate 502 away from rotating shaft 10. The upper surface of release piece 901 is slidably connected to the surface of sliding shaft 902. Mounting piece 4 is an elastic arc piece. An elastic groove 17 is opened on the surface of mounting piece 4. The elastic groove 17 has a central part. There is a neutral plate 18, the length of which is greater than the length of the elastic groove 17. When the mounting plate 4 bends inward, the mounting plate 4 is tightly attached to the outer surface of the clamp 1. When it is necessary to adjust the position of the nasal oxygen tube, the release component 9 is operated to press the release plate 901. The release plate 901 rotates around the connection point with the outer side of the mounting groove 7 and the support plate 14. Since the upper surface of the release plate 901 is slidably connected to the surface of the sliding shaft 902, and the sliding shaft 902 is fixed at the end of the toothed plate 502 away from the rotating shaft 10, the rotation of the release plate 901 will drive the toothed plate 502 to rotate around the rotating shaft 10, so that the second tooth 8 at the bottom of the toothed plate 502 separates from the first tooth 6 on the outer side of the toothed sleeve 501. At this time, the oxygen supply tube 2 can be freely adjusted in the toothed sleeve 501. After adjusting the position in step 1, release the release plate 901. Under the action of the torsion spring 11, the locking plate 502 resets, and the second locking tooth 8 engages with the first locking tooth 6 again, fixing the position of the oxygen supply tube 2. The mounting plate 4 is an elastic arc plate. When it is necessary to wear the nasal oxygen tube, the mounting plate 4 can be bent outward, and then the two ends of the clamp 1 can be inserted into the hair. Then the mounting plate 4 is bent inward so that the mounting plate 4 is close to the outer surface of the clamp 1. The mounting plate 4 and the clamp 1 clamp the hair to fix it. By adjusting the position of the oxygen supply tube and the cooperation between the mounting plate 4 and the clamp 1, the device can be more tightly fixed to the human body, reducing the possibility of the device falling off during use when the patient makes small movements.

[0023] Among them, such as Figure 1 as well as Figure 2 As shown, the mounting groove 7 has through holes 12 at both ends, and a limiting step 13 at the bottom of the mounting groove 7. The height of the limiting step 13 exceeds the position of the through hole 12. A buffer pad 15 is provided on the surface of the mounting piece 4. The buffer pad 15 is located between the mounting groove 7 and the support plate 14. A protective cover 16 is provided on the outside of the mounting groove 7 and the support plate 14. The release piece 901 extends out from one side of the protective cover 16. The limiting step 13 restricts the position of the toothed plate 502 to prevent excessive displacement of the toothed plate 502 from squeezing the supply pipe. The buffer pad 15 reduces the vibration of the release piece 901 during use, making the use process more comfortable. The protective cover 16 protects the equipment.
