Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0022] Please see Figure 1-6 This utility model provides a technical solution: a breathing device for non-invasive ventilation in painless gastrointestinal endoscopy, including a hollow head cover 1, an air bladder 5 fixedly disposed on the lower circumference of the head cover 1, an inflation tube 9 fixedly connected to one side of the air bladder 5, two restraint straps 6 hinged to the lower front of the head cover 1, two belt loops 12 fixedly connected to the lower rear of the head cover 1, locking components fixedly connected to the restraint straps 6, and two or more hollow connectors 2 fixedly connected to the outer circumference of the front of the head cover 1, quick-change components inserted into the inner side of each connector 2, and the front end of the quick-change components having external threads.

[0023] First, connect one end of the breathing tube to the external thread of the quick-change component for pre-assembly. Connect the other end of the breathing tube to the external ventilator. When the device is to be used, quickly insert the quick-change component connected to the breathing tube into the connector 2. Cover the patient's head with the head cover 1. Then, connect one quick-change component to the other connector 2. Insert the guide wire with the gastroscope into the connector 2 and insert it into the patient's stomach through the patient's mouth. Pressurize the cuff 5 to fix the head cover 1 to the patient's neck. Then, pass the two restraint straps 6 under the patient's armpits and further fix the head cover 1 to the patient's head with the locking component. After the patient has completed the gastroscopy, remove the guide wire and use the cap 4 with internal threads to seal the quick-change component where the guide wire was removed.

[0024] The quick-change component includes a connecting pipe 3 that is inserted into the inner side of the connector 2. A hemispherical long groove 13 is opened at the upper rear end of the connecting pipe 3. A sunken hemispherical groove is connected to the front end of the hemispherical long groove 13. A spherical stop 15 is contacted and connected to the inner wall of the sunken hemispherical groove. A positioning rod 20 is fixedly connected to the upper side of the spherical stop 15. The positioning rod 20 is inserted into the connector 2.

[0025] When it is necessary to disconnect the quick-change component from the connector 2, the positioning rod 20 is pulled up, which causes the spherical stop 15 to move upward, so that the spherical stop 15 is disengaged from the sunken hemispherical groove. When the spherical stop 15 and the hemispherical groove 13 are at the same horizontal position, the connecting pipe 3 is moved forward to facilitate the disconnection of the connecting pipe 3 from the connector 2. The upper end of the positioning rod 20 is fixedly connected to a handle 17, which facilitates the adjustment of the upper and lower positions of the positioning rod 20.

[0026] A sleeve 16 is inserted into the outer side of the upper end of the positioning rod 20. Two annular grooves 18 are opened in the middle of the upper side of the connector 2. A tension spring 19 is fixedly connected to the upper end of the inner wall of the sleeve 16 and the bottom end of the annular groove 18. The tension spring 19 is sleeved on the outer side of the positioning rod 20. Two hemispherical limiting grooves 14 are opened in the inner wall of the connector 2. The annular groove 18 is connected to the limiting groove 14 on the same side.

[0027] When the connecting pipe 3 is moved to the inside of the connector 2, the spherical stop 15 slides along the hemispherical groove 13. When the sinking hemispherical groove on the connecting pipe 3 and the spherical stop 15 are in the same axial position, under the force of the tension spring 19, the spherical stop 15 moves downward and contacts the bottom of the sinking hemispherical groove, thereby fixing the position of the connecting pipe 3 inside the connector 2.

[0028] The locking component includes a first snap 7 that is fixedly connected to the lower end of the restraint strap 6. Multiple second snaps 8 are provided on the upper side of the first snap 7, and the second snaps 8 are fixedly connected to the restraint strap 6.

[0029] By passing the lower end of the restraint strap 6 through the loop 12, the first snap 7 is adjusted to match the position of different snaps according to the size of different patients, thus playing a role in assisting in fixing the head cover 1.

[0030] The restraint strap 6 is fitted with a cotton pad ring.

[0031] The cotton padding rings effectively protected the patient's armpits from strangulation.

[0032] One end of the inflation tube 9 is threadedly connected to a cap 10, and the cap 10 is fixedly connected to a strap 11. The other end of the strap 11 is fixedly connected to the inflation tube 9.

[0033] After the head cover 1 is placed over the patient's head, the inflation tube 9 is connected to the external pressurization device. By turning on the external pressurization device, the inside of the airbag 5 is pressurized, thereby making the airbag 5 fit tightly against the patient's neck. The middle of the inflation tube 9 is bent to seal the connection between the airbag 5 and the outside. After removing the external pressurization device, the inflation tube 9 is sealed by tightening the cap 10.

[0034] In use, this invention first connects one end of the breathing tube to the external thread of the quick-change component for pre-assembly. The other end of the breathing tube is connected to an external ventilator. When the device is in use, the quick-change component connected to the breathing tube is inserted into the connector 2, and the head cover 1 is placed over the patient's head. Then, after connecting one quick-change component to another connector, the guide wire with the gastroscope is inserted into the connector 2 and sent into the patient's stomach through the patient's mouth. By pressurizing the air bag 5, the head cover 1 is fixed to the patient's neck. Then, two restraint straps 6 are passed under the patient's armpits, and the head cover 1 is further fixed to the patient's head by the locking component. After the patient has completed the gastroscopy, the guide wire is pulled out, and the quick-change component at the point where the guide wire was pulled out is sealed with a threaded cap 4.

[0035] 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.
