the cover bag 5 is provided with a connecting piece 7 which is integrally formed with the cover bag 5;

a machine end interface 1 is arranged at the inlet end of the airway conduit 4, a drainage tube 2 is arranged in the airway conduit 4, the drainage tube 2 extends into the mask bag 5 and is communicated with a drainage hole 6, and an anti-backflow mechanism 21 capable of preventing backflow of vomit is arranged on the inner wall of one end of the drainage tube 2, which is positioned in the mask bag 5;

the backflow preventing means 21 comprises a plug assembly 212 moving along the length of the drainage tube 2, and the plug assembly 212 is composed of a sealing plug 2123 and an elastic member;

the backflow prevention mechanism 21 further comprises a hard rubber hose 211, a protruding part 213 is arranged on the inner wall of the hard rubber hose 211, and the inner wall of the protruding part 213 is in embedded clamping connection with the outer wall of the sealing plug 2123;

the elastic element consists of a connecting piece 2121 and a silica gel connecting rod 2122, wherein the connecting piece 2121 is arranged on the hard rubber tube 211, and the connecting piece 2121 is elastically connected with the sealing plug 2123 through the silica gel connecting rod 2122;

a one-way valve for one-way control is arranged on the drainage tube 2, and the drainage tube 2 is connected with a negative pressure drainage device;

when the drainage tube 2 conducts drainage decompression on the stomach and intestine of a patient, the mixture in the stomach and intestine of the patient flows into the drainage tube 2, and the mixture will impact the sealing plug 2123, at which point the sealing plug 2123 will move along the boss 213 of the hose 211 to the outside of the mouth, so that the sealing plug 2123 presses the silicone connecting rod 2122 to be pressed against one side of the connecting piece 2121, thereby separating the sealing plug 2123 from the boss 213, conducting the channel of the anti-backflow mechanism 21, realizing the drainage operation of the gastrointestinal mixture, when the drainage tube 2 does not conduct water, the long normal pressure state is recovered in the drainage tube 2, at the moment, the silica gel connecting rod 2122 can reset and rebound, thereby driving the sealing plug 2123 into the boss 213 in the hose 211 again, and contacts with the inner wall of the convex part 213 to close the drainage channel of the drainage tube 2, so as to prevent the gastrointestinal mixture remained in the drainage tube 2 from flowing back to the esophagus of the patient and avoid the vomiting of the patient;

an airway tube connector is arranged on the machine end interface 1, and the airway tube connector is communicated with a breathing pipeline of a breathing machine and used for communicating a breathing passage of an airway of a patient to help the patient breathe.

In the embodiment, before the inflation-free throat tube is used, the machine end interface 1 in the airway tube 4 is connected with a breathing machine, the drainage tube 2 is connected with a negative pressure drainage device to conduct a connecting pipeline of a laryngeal mask, then the mask 5 is inserted into the throat from the oral cavity of a patient, the airway tube 4 is pushed to enable the back surface of the mask 5 to be attached to the esophagus part of the patient, the concave part 51 is communicated with the airway of the patient, when the mask 5 is inserted into the throat position of the patient, the mask 5 is in close contact with the inner wall of the airway of the patient, at the moment, the breathing machine can be communicated with the airway of the patient through the airway tube 4 to realize the auxiliary respiration of the patient, when the gastrointestinal pressure of the patient is higher, the outlet end of the drainage tube 2 is connected to the negative pressure drainage device to suck, at the moment, the gas or fluid in the stomach intestine of the patient can enter the drainage tube 2 with negative pressure through, and the gastrointestinal mixture is pressed against the plug head assembly 212, so that the sealing plug 2123 presses the silica gel connecting rod 2122 to compress and deform the silica gel connecting rod 2122, and at the moment, the sealing plug 2123 is separated from the boss 213 in the hard rubber tube 211, so that the drainage channel of the drainage tube 2 is conducted, and the drainage tube 2 can perform decompression treatment on the gastrointestinal tract of the patient.

As shown in fig. 1 and 3, the device further comprises a support mechanism 3, wherein the support mechanism 3 comprises a collar 32 sleeved on the airway tube 4, and the collar 32 moves along the length direction of the airway tube 4;

the air bag 33 is sleeved on the outer wall of the lantern ring 32, an opening of the air bag 33 is communicated with the inflation channel conduit 31, and the inflation channel conduit 31 penetrates through the end face of the lantern ring 32 and extends outwards.

Open the back when patient's oral cavity muscle for a long time, can lead to patient's oral cavity muscle strain, promote lantern ring 32 this moment and make it move to the palate position about patient's oral cavity to leading-in gas in the gas-filled duct pipe 31, make gas enter into gasbag 33 in make gasbag 33 inflation grow, strut patient's oral cavity, thereby prevent that patient's oral cavity muscle strain back is closed and cause airway pipe 4 by the phenomenon of extrusion deformation, ensured the patency that airway pipe 4 ventilates.

As shown in fig. 2, the covering bag 5 is provided with a concave part 51, the inner wall of the concave part 51 is provided with a support 52, the support 52 is provided with a through hole 53 communicated with the esophagus, the covering bag 5 is of an inflation-free flexible structure, when the covering bag 5 is embedded into the airway, the cover bag 5 can be subjected to a large extrusion force of the inner wall of the patient, and at the moment, the support effect of the support 52 can be achieved, so that the covering bag 5 can be reinforced and supported, the covering bag 5 is in a relatively relaxed opening state, the phenomenon that the covering bag 5 is deformed and closed due to the extrusion effect is prevented, and the auxiliary opening of the through hole 53 facilitates light rays to pass through the through hole 53 from the airway tube 4 and enter the covering bag 5, so that whether the covering bag 5 is inserted into a proper and accurate position is judged, and the use accuracy of the laryngeal.
