The sliding buckle is made of PE material, while the other components are made of PVC material. It is sterile and sterilized with ethylene oxide. It is used in cases of burns or carbon monoxide poisoning where oxygen needs to be supplied to increase the dissolved oxygen level in the patient's blood, ensuring the normal functioning of the patient's body.

[0003] There is a disposable nasal oxygen cannula (CN201921047827.2) that uses a threaded tube structure to buffer and slow down the direct airflow, reducing the damage to the patient's nasal cavity caused by sudden changes in oxygen flow rate. However, it has shortcomings. Existing devices have a detachable structure, which may lead to cross-infection due to repeated use. Traditional ear loop fixation is prone to slippage, the nasal plug material is too hard and can cause pressure sores, and flow adjustment requires an external connection, making it inconvenient to use. Therefore, a disposable nasal oxygen cannula is needed to solve the above problems. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-7 This utility model provides a technical solution: a disposable nasal oxygen tube, including a catheter 1, a transverse catheter 2, a fixing strap 3, a pad 4, an installation connector 5, a spiral pattern 6, a clamping pad 7, a clamping seat 8, an adhesive seat 9, an adhesive block 10, a nasal plug head 11, a nasal plug tube 12, a rotating groove 13, a guide hole 14, a rotating block 15, a movable valve 16, an installation interface 17, a locking buckle 18, a locking buckle groove 19, an installation insert 20, and an air inlet 21. One end of the catheter 1 is connected to the transverse catheter 2, and the other end of the catheter 1 is connected to the installation interface 17. The catheter 1 is clamped and coiled by the clamping pad 7 and the clamping seat 8. The spiral pattern 6 is distributed in a protruding spiral on the inner wall of the catheter 1. The rotating groove 13 and the rotating block 15 are integrated on the catheter 1. The catheter 1, the transverse catheter 2, the rotating groove 13, the rotating block 15, and the installation interface 17 are non-removable structures, which makes it easy to cross-coil the catheter 1 and convenient to store.

[0022] A rotating groove 13 is installed along the middle edge of the conduit 1, and a rotating block 15 is rotatably embedded in the inner wall of the rotating groove 13. A guide hole 14 is provided on the inner wall of the rotating block 15. A spiral thread 6 is fixedly connected to the inner wall of the conduit 1, and a clamping seat 8 is fitted onto one side of the outer wall of the conduit 1. Clamping pads 7 are fixedly connected to both sides of the inner wall of the clamping seat 8. An air inlet 21 is installed at one end of the inner wall of the installation interface 17, and a movable valve 16 is installed on the outer wall of the air inlet 21. A locking buckle 18 is elastically and movably connected to the outer wall of the installation interface 17. An installation plug 20 is inserted into the inner wall of the interface 17. The outer wall of the installation plug 20 has a locking groove 19. One end of the installation plug 20 is connected to an installation connector 5. The installation connector 5 is locked to the installation interface 17 by the locking plug 18 and the locking groove 19. The installation connector 5 is connected to the installation interface 17 in a one-way manner by the movable valve 16 and the air guide port 21. This makes it easy for the installation connector 5 to be quickly locked to the installation interface 17 and can stably guide air in one direction to avoid excessive flow rate.

[0023] The locking buckle 18 is fastened to the locking buckle groove 19. The other side of the horizontal tube 2 is connected to the vertically installed nasal plug tube 12, and the outer wall of the nasal plug tube 12 is fitted with the nasal plug head 11. The nasal plug head 11 is made of biomimetic silicone composite material and has a three-layer gradient hardness structure, which makes the nasal plug head 11 more comfortable to wear.

[0024] Adhesive seats 9 are rotatably installed at both ends of the transverse conduit 2, and adhesive blocks 10 are attached to one side of the adhesive seats 9. The adhesive seats 9 are connected to the fixing straps 3 by adhesive blocks 10, and the adhesive blocks 10 are rotatably connected to the transverse conduit 2 by the adhesive seats 9. This makes it easy to quickly attach and detach the fixing straps 3, and provides good fit.

[0025] One end of the adhesive block 10 is fixedly connected to the fixing strap 3, and a pad 4 is fixedly connected to one side of the fixing strap 3. The fixing strap 3 is elastically and stretchably connected to the transverse catheter 2. The fixing strap 3 is made of breathable non-woven fabric. The pad 4 is distributed in a wrapping position on the back side of the outer wall of the fixing strap 3. The pad 4 is made of medical-grade pressure-sensitive adhesive. This makes the fixing strap 3 more comfortable to wear and convenient to use.

[0026] Working principle: When using this disposable nasal oxygen cannula, firstly, the cannula 1 of the device is locked and installed by inserting it into the mounting connector 5 through the locking buckle 18 and locking groove 19. Then, the horizontal cannula 2 is tied to the head and worn through the fixing strap 3. Next, it is inserted into the nose through the nasal plug head 11 and nasal plug tube 12. When the flow rate needs to be adjusted, the guide hole 14, rotating block 15 and rotating groove 13 can be rotated for adjustment. When the cannula 1 is too long, it can be clamped and curled by the clamping pad 7 and clamping seat 8. When the cannula 1 is folded, it can be reinforced by the spiral 6. When the fixing strap 3 is damaged, it can be quickly replaced by the adhesive seat 9 and adhesive block 10. This is the usage process of this disposable nasal oxygen cannula.

[0027] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
