Preferably, the diameter of the top of the limiting tube is larger than the diameter of the bottom thereof, and the inner diameter of the top of the limiting tube is the same as the inner diameter of the bottom thereof.

Preferably, the inside of the nasal plug is provided with a limiting groove adapted to the limiting tube, and the material of the nasal plug is a soft material.

Preferably, the length of the second elastic band is greater than the length of the first elastic band, and a limit buckle adapted to the second elastic band is hinged at one end of the first elastic band away from the hinge piece.

Preferably, the top of the nasal plug is semicircular and the diameter is that of the nostril.

Compared with the prior art, the beneficial effects of the present utility model are as follows:

The utility model solves the problem of the nasal congestion blocking the entire nostril and the defects of the wearing method by providing a three-way adapter, a connecting conduit, a bell mouth, a limit tube, a nasal obstruction, a first elastic band and a second elastic band, and has the advantages of changing the nasal obstruction. The front-end shape of the catheter and the advantages of adding a fixing device, the oxygen nasal cannula can not block the nostrils by changing the front-end shape of the nasal cannula, and a fixing device is added to prevent falling off.

Detailed ways

The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the implementations. example. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the present invention.

Please refer to Figure 1-3, an oxygen nasal cannula, including a three-way adapter 1, the bottom of the three-way adapter 1 is connected with a connecting conduit 2, and the other end of the connecting conduit 2 is sleeved with a bell mouth 3, and the three-way Both sides of the top of the adapter 1 are connected to the limit tube 4, the surface of the limit tube 4 is sleeved with a nose plug 5, and both sides of the three-way adapter 1 are welded with hinges, and the right side of the three-way adapter 1 is welded. The side is hinged with a first elastic band 6 through a hinge, and the left side of the three-way adapter 1 is hinged with a second elastic band 7 through a hinge. 3. The limiting tube 4, the nasal plug 5, the first elastic band 6 and the second elastic band 7 solve the problem that the nasal plug 5 blocks the entire nostril and the wearing method has defects, and has the advantages of changing the front end shape of the nasal cannula and adding a fixing device , The oxygen nasal cannula changes the shape of the front end of the nasal cannula so as not to block the nostrils, and additionally adds a fixing device to prevent falling off.

In this embodiment, the diameter of the top of the limiting tube 4 is larger than the diameter of the bottom, and the inner diameter of the top of the limiting tube 4 is the same as the inner diameter of the bottom. By setting the limiting tube 4, it is convenient for medical staff to regularly replace the nasal plug 5 .

In this embodiment, the inside of the nasal plug 5 is provided with a limit groove that is adapted to the limit tube 4, and the material of the nasal plug 5 is a soft material. By arranging the nasal plug 5, the material is relatively soft, which can effectively improve the comfort of the patient. .

In this embodiment, the length of the second elastic band 7 is greater than the length of the first elastic band 6, and the end of the first elastic band 6 away from the hinge is hinged with a limit buckle 8 adapted to the second elastic band 7. By setting The first elastic band 6, the second elastic band 7 and the limit buckle 8 can enable the medical staff to effectively fix the oxygen nasal cannula on the patient's body, thereby preventing it from falling off.

In this embodiment, the top of the nasal plug 5 is semicircular, and the diameter is half of the nostril. By changing the shape of the front end of the nasal plug 5, the nasal plug 5 is prevented from blocking the patient's nasal cavity, and the comfort of the patient is improved.

Working principle: When using, the medical staff first docks the bell mouth 3 with the oxygen delivery device, replaces the nasal plug 5 suitable for the patient, then inserts the nasal plug 5 into the patient's nasal cavity, and then uses the second elastic band 7 to bypass the patient's head. Then use the limit buckle 8 of the first elastic band 6 to hinge on the left side of the patient, and adjust it to an appropriate length, and then deliver oxygen, which is transmitted to the three-way adapter 1 through the connecting catheter 2 under the action of pressure. Inside, then the three-way adapter 1 delivers oxygen into the patient's nasal cavity through the cooperation of the limiting tube 4 and the nasal plug 5 .

Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes and modifications can be made to these embodiments without departing from the principles and spirit of the present invention , alternatives and modifications, the scope of the present invention is defined by the appended claims and their equivalents.
