DETAILED DESCRIPTION OF THE EMBODIMENTS

[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0023] Refer toFigures 1-4 , an airtight endotracheal tube, comprising an intubation body 1. The intubation body 1 includes an inflation connecting tube 2. A connecting component 4 is arranged on one side of the inflation connecting tube 2, and an inflation component 3 is connected to one side of the inflation connecting tube 2 through the connecting component 4. The connecting component 4 includes a fixing ring 41. Clamping cavities 42 are opened at both ends of the fixing ring 41. An air flow channel 44 is penetrated through the fixing ring 41 between the two clamping cavities 42. An auxiliary tube 43 is fixedly installed outside the air flow channel 44 in the clamping cavity 42;

[0024] Meanwhile, an auxiliary component 45 is arranged outside the clamping cavity 42 in the fixing ring 41. A magic sticker layer 46 is arranged on the outer wall of the fixing ring 41 at the position of the auxiliary component 45, and the auxiliary component 45 is adhered to the magic sticker layer 46;

[0025] The two ends of the fixing ring 41 are symmetrically provided with insertion grooves 47. A medical transparent film winding group 48 is inserted on the outer wall of the insertion groove 47, and a limiting ring 49 is screwed on the outer wall of the insertion groove 47 outside the medical transparent film winding group 48.

[0026] Meanwhile, the auxiliary component 45 includes three elastic straps 451. The three elastic straps 451 are located in the fixing ring 41, and a card slot is opened in the fixing ring 41 at the position of the elastic strap 42.

[0027] Moreover, one end of the elastic strap 42 is connected to the inner wall of the card slot, the other end of the elastic strap 42 is connected to a flexible block 452, and magic patches are arranged on the outer walls of the flexible blocks 452.

[0028] Moreover, a placement cavity is opened in one side of the limiting ring 49 at the position of the medical transparent film winding group 48, and an external thread part is arranged on the other side of the limiting ring 49. An internal thread part is arranged at the external thread part in the insertion groove of the fixing ring 41, and the internal thread part is in threaded connection with the external thread part.

[0029] Furthermore, the inflation component 3 includes an auxiliary connecting tube. An indicating balloon body and a one-way valve body are sequentially arranged at one end of the auxiliary connecting tube. It should be noted that the specific structures and working principles of the indicating balloon body, the one-way valve body of the inflation component 3 and the intubation body 1 are all existing technologies publicly available on the market at present, and do not belong to the main technical problems to be solved in the present invention, so no more details are described.

[0030] Furthermore, the outer diameter of the inflation connecting tube 2 is the same as the outer diameter of the auxiliary connecting tube, and the outer diameter of the inflation connecting tube 2 is the same as the inner diameter of the clamping cavity 42. The inner diameter of the inflation connecting tube 2 is the same as the outer diameter of the auxiliary tube 43, and the length of the auxiliary tube 43 is greater than the depth of the clamping cavity 42.

[0031] In the present invention, through the provision of the connection assembly 4, the inflating assembly 3 and the intubation body 1 are detachable. And when the inflating assembly 3 is damaged, the inflating assembly 3 can be replaced individually without replacing the tracheal intubation as a whole, so as to quickly maintain and reduce the downtime.

[0032] By sleeving the inflating connection tube 2 on the outer wall of the auxiliary tube 43 on one side of the connection assembly 4 and being located in the corresponding clamping cavity 42, then holding the flexible block 452 and pulling it outwards until it is tightened and adhered to the magic sticker layer 46 after being tightened, so that the elastic band 451 presses against the outer wall of the inflating connection tube 2, making the inner diameter of the inflating connection tube 2 press against the outer diameter of the auxiliary tube 43, ensuring the stability after the inflating connection tube 2 and the auxiliary tube 43 are sleeved. And when inflating into the inflating connection tube 2 and the auxiliary tube 43, it prevents gas leakage due to loosening of the connection between the inflating connection tube 2 and the auxiliary tube 43 caused by external force or vibration, ensuring the sealing performance after the inflating connection tube 2 and the auxiliary tube 43 are sleeved.

[0033] Then, after the limit ring 49 is loosened by screwing, the medical transparent film winding group 48 is moved towards the auxiliary tube 43 and the inflating connection tube 2, and the outer wall of the inflating connection tube 2 on one side of the connection ring 41 is wound, so as to further fix the auxiliary tube 43 and the inflating connection tube 2, ensuring the stability of the connection between the auxiliary tube 43 and the inflating connection tube 2.

[0034] At the same time, the auxiliary connection tube is sleeved on the outer wall of the auxiliary tube 43 on the other side of the connection assembly 4 and is located in the corresponding clamping cavity 42. Then, holding the flexible block 452 and pulling it outwards until it is tightened and adhered to the magic sticker layer 46 after being tightened, so that the elastic band 451 presses against the outer wall of the inflating connection tube 2, making the inner diameter of the auxiliary connection tube press against the outer diameter of the auxiliary tube 43, ensuring the stability after the auxiliary connection tube and the auxiliary tube 43 are sleeved. And when inflating into the auxiliary connection tube and the auxiliary tube 43, it prevents gas leakage due to loosening of the connection between the auxiliary connection tube and the auxiliary tube 43 caused by external force or vibration, ensuring the sealing performance after the auxiliary connection tube and the auxiliary tube 43 are sleeved.

[0035] Then, after the limit ring 49 is loosened by screwing, the medical transparent film winding group 48 is moved towards the auxiliary tube 43 and the auxiliary connection tube, and the outer wall of the inflating connection tube 2 on one side of the connection ring 41 is wound, so as to further fix the auxiliary tube 43 and the auxiliary connection tube 2, ensuring the stability of the connection between the auxiliary tube 43 and the auxiliary connection tube, and completing the connection between the intubation body 1 and the inflating connection tube 2.

[0036] In the present invention, through the provision of the connection assembly 4, the inflating assembly 3 and the intubation body 1 are detachable. And when the inflating assembly 3 is damaged, the inflating assembly 3 can be replaced individually without replacing the tracheal intubation as a whole, so as to quickly maintain and reduce the downtime.

[0037] The above are only the preferred specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, making equivalent substitutions or changes should be covered by the protection scope of the present invention.
