Description

Technical Field

[0001] The utility model relates to the technical field of nasal oxygen tubes, in particular to a replacement head of a nasal oxygen tube. Background Art

[0002] A nasal oxygen cannula is a medical device used to deliver oxygen to the patient's nasal cavity. It is made of soft plastic material, one end of which is connected to the oxygen source and the other end is inserted into the user's nostrils to supply oxygen to the user. In a plateau environment, due to the high altitude of the plateau, users who go to the plateau to play often need to breathe oxygen. By connecting one end of the nasal oxygen cannula to the oxygen source and inserting the air outlet at the other end into the user's nostrils, the user can breathe oxygen, effectively preventing the occurrence of altitude sickness.

[0003] When the user is on the plateau, the air is thin due to the high altitude. Users who go to the plateau for fun often need to breathe oxygen frequently. Nasal oxygen cannulas are disposable. Frequent oxygen breathing requires the entire nasal oxygen cannula to be replaced multiple times. The cost of oxygen breathing needs to be reduced. Utility Model Content

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] See also Figure 1-5 The utility model discloses a nasal oxygen tube replacement head, comprising an oxygen tube 1, a connecting tube 2 and an air outlet head 3, wherein the number of the air outlet heads 3 is two and the air outlet heads 3 are connected to the connecting tube 2, and further comprising:

[0025] The anti-backflow head 4 is provided on the top of the air outlet head 3. The top of the anti-backflow head 4 is in a closed shape, and the air flows out from the side of the anti-backflow head 4, so as to prevent the nasal mucus from flowing back into the connecting tube 2;

[0026] The connecting assembly 5 includes a plug 51 fixed to the end of the oxygen tube 1 and a socket 53 fixed to the end of the connecting tube 2. The plug 51 is inserted into the socket 53. The plug 51 is truncated into the socket 53. The shape of the socket 53 is adapted to the shape of the plug 51. The surface of the plug 51 fits tightly with the inner wall of the socket 53. A clamping ring 52 is fixed on the surface of the plug 51. The clamping ring 52 is made of rubber. The surface of the clamping ring 52 is movably connected to the inner wall of the socket 53. The friction between the plug 51 and the socket 53 is increased by the clamping ring 52, thereby improving the tightness of the connection between the plug 51 and the socket 53.

[0027] Specifically, the backflow prevention head 4 includes a round head 41 fixed on the air outlet head 3 and an air outlet hole 43 opened on the side of the round head 41 , and an air flow dispersion block 42 is fixed on the top of the inner wall of the round head 41 .

[0028] In this implementation plan, please refer to Figure 2 The air outlet 43 is opened on the side of the round head 41 so that the top of the round head 41 is closed, which effectively prevents nasal mucus from entering the connecting tube 2. When the airflow flows to the airflow dispersion block 42, it automatically disperses to the surroundings to prevent the airflow from accumulating at the top of the inner wall of the round head 41.

[0029] Specifically, there are a plurality of air outlet holes 43 , and the air outlet holes 43 are inclined.

[0030] In this implementation plan, please refer to Figure 2 The air outlet holes 43 are inclined, so that when the air flows upward, it can flow out along the inclined air outlet holes 43, and there are multiple air outlet holes 43, and the multiple air outlet holes 43 are distributed in a circular array with the center of the round head 41 as the center of the array, thereby reducing the resistance of the air flow when it flows out from the round head 41, making the air flow smoother.

[0031] Specifically, the surface of the airflow dispersion block 42 is a curved surface, which is used to guide the airflow.

[0032] In this implementation plan, please refer to Figure 5 When the airflow flows to the airflow dispersion block 42 , it is automatically dispersed to the surroundings due to the effect of the curved surface, so that the airflow is discharged from the air outlet 43 , preventing the airflow from accumulating at the top of the inner wall of the round head 41 .

[0033] Specifically, the surface of the clamp ring 52 is a curved surface, and the shape of the inner wall of the socket 53 matches the shape of the clamp ring 52 .

[0034] In this implementation plan, please refer to Figure 4 By fitting the curved surfaces together, the connection between the socket 53 and the plug 51 is made tighter.

[0035] Specifically, two upper baffles 6 and two lower baffles 7 are fixed to the inner wall of the connecting pipe 2 . The two upper baffles 6 are located between the two lower baffles 7 , and both the upper baffles 6 and the lower baffles 7 are inclined.

[0036] In this implementation plan, please refer to Figure 3 When part of the nasal mucus enters the connecting tube 2, it will be blocked by the upper baffle 6 and the lower baffle 7, thereby preventing the nasal mucus from entering the oxygen tube 1 and contaminating the oxygen tube 1. The upper baffle 6 and the lower baffle 7 are both inclined to reduce the obstruction to the airflow.

[0037] Specifically, an elastic band 54 is fixed to the surface of the socket 53 , and a positioning head 55 is fixed to the surface of the plug 51 . The elastic loop on the elastic band 54 is sleeved on the positioning head 55 to ensure a stable connection between the socket 53 and the plug 51 .

[0038] In this implementation plan, please refer to Figure 4 The elastic band 54 is made of rubber, and the elastic loop on the elastic band 54 is sleeved on the L-shaped positioning head 55 to prevent the socket 53 from being separated from the plug 51, thereby ensuring a stable connection between the socket 53 and the plug 51.

[0039] The working principle and use process of the utility model are as follows: the elastic ring on the elastic band 54 is removed from the positioning head 55, and then the plug 51 is pulled out from the socket 53 to separate the oxygen tube 1 from the connecting tube 2. After separation, the connecting tube 2 and the air outlet head 3 can be replaced separately, without replacing the entire nasal oxygen tube, thereby reducing the oxygen inhalation cost of the user. When the connecting tube 2 and the oxygen tube 1 need to be connected, the plug 51 is inserted into the socket 53, the clamping ring 52 is tightly fitted with the inner wall of the socket 53, and then the elastic ring on the elastic band 54 is put on the positioning head 55 to achieve a stable connection between the plug 51 and the socket 53. After connection, the nasal oxygen tube can be used for oxygen inhalation;

[0040] The backflow prevention head 4 is fixed on the air outlet head 3, and the air outlet hole 43 is opened on the side of the backflow prevention head 4, which effectively prevents nasal mucus from entering the connecting tube 2. An upper baffle 6 and a lower baffle 7 are fixed in the connecting tube 2. When part of the nasal mucus enters the connecting tube 2, it will be blocked by the upper baffle 6 and the lower baffle 7, thereby preventing the nasal mucus from entering the oxygen tube 1 and contaminating the oxygen tube 1.
