[0064] The oropharyngeal ventilation tube 1000 with a braided tape capable of fixing an oxygen inhalation tube 2000 according to an embodiment of the present invention will be described in detail below with reference to the accompanying drawings.

[0065] Reference Figures 1 to 5 As shown, the oropharyngeal ventilation tube 1000 with a braided belt for fixing an oxygen inhalation tube 2000 provided according to an embodiment of the utility model comprises a tube body 10 and a stop guard 20 arranged outside the front end of the tube body 10, and is characterized in that it also comprises a head strap 30;

[0066] Wherein, the head strap 30 is fixed on the stop guard 20;

[0067] In addition, the front end of the tube body 10 extends forward and is provided with a fixing ring 101 located in front of the stopping guard 20 for fixing the oxygen tube 2000. The front end surface of the stopping guard 20 is close to the fixing ring 101 and is provided with a plug hole 201 that penetrates to its rear end surface for the oxygen tube 2000 to pass through.

[0068] Based on the above, it is clear that when the present application is implemented, it is mainly used as an oropharyngeal ventilation tube 1000 with a braided tape to fix the oxygen inhalation tube 2000.

[0069] Specifically, when using the present application, insert the present application into the patient's mouth so that the rear end surface of the blocking guard 20 is against the outside of the patient's lips, and the head strap 30 is fixed to the patient's head. In this way, the present application can be easily used.

[0070] The use of the above-mentioned application will obviously have the following technical effects:

[0071] First, the present application is provided with the head strap 30. After it is fixed to the patient's head with a suitable tightness, the tube body 10 inserted into the patient's mouth is not easy to slip off, so that the present application has good fixing stability and good reliability in use.

[0072] Second, when the patient needs to be given oxygen through the mouth, Figure 5As shown, the oxygen tube 2000 used can be inserted into the patient's oral cavity to a certain depth through the insertion hole 201, and then the medical tape is wrapped around the insertion hole 201 and the outside of the fixing ring 101. In this way, the oxygen tube 2000 used can be fixed as a whole with the fixing ring 101, so that the oxygen tube 2000 used is not easy to swing or fall out, and it also has good fixing stability and good reliability in use.

[0073] Furthermore, through the above-mentioned optimized design, the overall structure of the present application is highly practical and has good use effect.

[0074] Furthermore, in the specific implementation, Figure 2 and Figure 4 As shown, according to one embodiment of the utility model, the front end outer wall of the fixing ring 101 is provided with an anti-slip outer edge A1011 protruding outward, and the part of the anti-slip outer edge A1011 located on one side of the insertion hole 201 is provided with a notch groove 10111 suitable for the oxygen inhalation tube 2000 to pass through in the front-to-back direction.

[0075] In this regard, it is clear that when the present application is actually used to fix the oxygen tube 2000, the medical tape used is wrapped around it and the outside of the fixing ring 101, so that the oxygen tube 2000 used is fixed as a whole with the fixing ring 101. At this time, the wrapped and fixed medical tape is stopped by the anti-slip outer edge A1011, making it difficult to slide off the fixing ring 101, so that the oxygen tube 2000 used is better fixed and more reliable.

[0076] Furthermore, in the specific implementation, continue to compare Figure 2 and Figure 4 As shown, according to one embodiment of the utility model, a sputum stopping plate 1012 for stopping sputum from overflowing is provided at the front inner lower part of the fixing ring 101 .

[0077] Therefore, when using the present application, there may be sputum in the patient's mouth. After the produced sputum enters the tube body 10, it can be stopped by the sputum stopping plate 1012, so that it can better prevent overflow and soil the patient's body, clothes or bed, so that the overall use effect of the present application can be effectively improved.

[0078] In addition, in this technical solution, or control Figure 2 and Figure 4 As shown, according to one embodiment of the utility model, a sputum suction cotton block 1013 for sucking sputum is provided at the rear inner lower part of the fixing ring 101.

[0079] Therefore, when using the present application, there may be sputum in the patient's mouth. After the produced sputum enters the tube body 10, it can be absorbed by the sputum suction cotton block 1013, so that it can better prevent overflow and stain the patient's body, clothes or bed, making the overall use effect of the present application better.

[0080] Furthermore, in the specific implementation, we still refer to Figure 2 and Figure 4 As shown, according to one embodiment of the utility model, the front end face of the stopping guard 20 is close to the left and right sides of the fixing ring 101 and has a socket 201 penetrating to its rear end face, and the left and right sides of the anti-slip outer edge A1011 are respectively provided with a notch groove 10111.

[0081] Therefore, it can be clearly seen that the present application is provided with two said sockets 201. When necessary, one of the said sockets 201 can be used to insert the oxygen tube 2000 for the patient to use, and the other said socket 201 can be used to insert the gastric tube for the patient to use, so that the present application is more flexible to use.

[0082] Again, in the specific implementation, Figure 1 and Figure 3 As shown, according to one embodiment of the present utility model, the pipe body 10 includes a straight pipe 10a and a curved pipe 10b connected to the middle of the rear end of the straight pipe 10a and arched upward;

[0083] The straight tube 10a is made of hard plastic material, and a circle of anti-slip outer edge B10a1 is protruding outward from the middle of the straight tube 10a; the curved tube 10b is made of soft rubber material, and a plurality of sputum overflow holes 10b1 are evenly opened on the outer wall of the lower part of the curved tube 10b from front to back.

[0084] From this, it can be clearly seen that:

[0085] On the one hand, due to the provision of the anti-slip outer edge B10a1, when the patient's teeth bite on the straight tube 10a, the inner side of the teeth can be stopped and limited by the anti-slip outer edge B10a1, making it more difficult for the present application to shift forward and backward along the patient's mouth after being inserted into the patient's mouth, thereby further improving the overall stability of the present application.

[0086] On the other hand, when the inner end of the curved tube 10b approaches the patient's throat, since the curved tube 10b is made of soft rubber material, its texture is soft, so that its inner end is not easy to hurt the patient's throat, making the application more comfortable and safe to use.

[0087] Furthermore, after the sputum produced in the patient's mouth enters the curved tube 10b and / or the straight tube 10a of the tube body 10, it can flow back into the patient's mouth through the multiple overflow holes to be swallowed, so that it will not be excessively concentrated in the curved tube 10b and / or the straight tube 10a.

[0088] Furthermore, through the above-mentioned optimization design, the overall use effect of the present application can be effectively improved.

[0089] Preferably, in this technical solution, continue to control Figure 1 and Figure 3 As shown, according to one embodiment of the present invention, the head strap 30 includes a first strap 301 and a second strap 302;

[0090] The connecting end of the first tie 301 is connected to the left end of the blocking guard 20 , and the connecting end of the second tie 302 is connected to the right end of the blocking guard 20 .

[0091] Therefore, when using the present application, the first strap 301 and the second strap 302 are wrapped around the back of the patient's head and the ends thereof are fastened, so that the entire present application can be easily fixed, thus making the present application convenient and easy to use.

[0092] And preferably, in this technical solution, or control Figure 1 and Figure 3 As shown, according to one embodiment of the utility model, the first lace 301 includes a male Velcro strap 3011, a first braid 3012, and a first elastic band 3013 connected between the male Velcro strap 3011 and the first braid 3012; the second lace 302 includes a female Velcro strap 3021, a second braid 3022, and a second elastic band 3023 connected between the female Velcro strap 3021 and the second braid 3022;

[0093] The end of the first braid 3012 is connected to the left end of the stop guard 20 ; the end of the second braid 3022 is connected to the right end of the stop guard 20 .

[0094] Therefore, when using the present application, on the one hand, by sticking the appropriate position of the male Velcro strap 3011 with the appropriate position of the female Velcro strap 3021, the first strap 301 and the second strap 302 can be easily and quickly wrapped around the back of the patient's head to fix the entire present application. On the other hand, since the present application is provided with the first elastic elastic band 3013 and the second elastic elastic band 3023, the length of the first strap 301 and the length of the second strap 302 of the present application can be fine-tuned, so that the first strap 301 and the second strap 302 can be flexibly wrapped around the back of the head of patients with different head outer diameters to fix the entire present application, making the present application highly adaptable.

[0095] Moreover, the first elastic band 3013 and the second elastic band 3023 both have certain elasticity and stretchability, so that when the first strap 301 and the second strap 302 are wrapped around the back of the patient's head to fix the entire application, they are not rigidly fastened, so as not to easily strangle the patient's head skin, etc., making the application more comfortable to use.

[0096] Other embodiments and the like are not described here by way of example.

[0097] In summary, the oropharyngeal ventilation tube 1000 provided in the present application has a braided strap for fixing the oxygen tube 2000. In a specific implementation, the present application is provided with the head strap 30. After it is fixed to the patient's head with an appropriate tightness, the tube body 10 inserted into the patient's mouth is not easy to slip off, so that the fixing stability of the present application is good, and the reliability of the present application is good.

[0098] Furthermore, when it is necessary to supply oxygen to the patient through the mouth, the oxygen tube 2000 can be inserted into the patient's mouth to a certain depth through the insertion hole 201, and then wrapped with medical tape around the insertion hole 201 and the outside of the fixing ring 101. In this way, the oxygen tube 2000 can be fixed to the fixing ring 101 as a whole, making it difficult for the oxygen tube 2000 to swing or fall out, so that it also has good fixing stability and good reliability.
