[0024] In the description of the present invention, it should be understood that the terms "center", "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific position, be constructed and operated in a specific position, and therefore cannot be understood as a limitation on the present invention. In the description of the present invention, unless otherwise specified, "multiple" means two or more.

[0025] The following specific embodiments are given to further clearly, completely and in detail illustrate the technical solution of the utility model. This embodiment is the best embodiment based on the technical solution of the utility model, but the protection scope of the utility model is not limited to the following embodiments.

[0026] Example 1

[0027] A choking-proof gastric tube comprises a gastric tube body 2 and an injection device 1 arranged at one end of the gastric tube body 2, wherein the gastric tube body 2 comprises a flow diversion cavity 6 arranged in the inner layer, and a closed cavity 5 formed between the inner wall and the outer wall of the gastric tube body 2, and a plurality of through holes 3 are correspondingly arranged on the side wall of the flow diversion cavity 6 at the inner end of the gastric tube body 2 and the outer wall of the closed cavity 5, and the through holes on the inner and outer walls correspond to each other; a closing device is arranged at the position corresponding to the through holes 3 in the closed cavity 5, and the closing device is connected to the control device at the external end of the gastric tube body 2, and when the closing device is opened, the through holes 3 on both sides penetrate to form a channel for liquid to enter and exit; when the closing device is closed, the channel is closed, and liquid cannot enter and exit the gastric tube. The through holes 3 facilitate the realization of the functions of gastric tube suction and injection, and ensure that the gastric tube is not easy to adsorb the inner wall of the stomach during the gastric fluid suction process.

[0028] Furthermore, the control device is an inflation device 9, and the closing device is an airbag 4. The airbag 4 is provided with a sealing ring 7 at the position corresponding to the through hole 3. The airbag 4 is connected to the inflation device 9 through an inflation tube 8 arranged on the side wall of the closed cavity 5. After inflation, the airbag 4 is deformed, and the sealing ring 7 expands and bulges toward the center to form a closed shape to close the through hole 3.

[0029] Furthermore, the inflation device 9 is an extruded airbag 4 or an inflation cylinder.

[0030] Furthermore, an air valve 10 is installed at one end of the inflation tube 8 close to the inflation device 9, and the gas in the airbag 4 is extracted through the air valve 10.

[0031] Furthermore, the stomach tube body is provided with a leakage detection device to detect whether the air bag 4 is leaking.

[0032] As an optional solution, the air leakage detection device is arranged at an end of the air valve away from the inflation device 9 .

[0033] Furthermore, the air leakage detection device selects a sensor as needed. In the present embodiment, a pressure sensor is optionally set. The pressure sensor is connected to the alarm. After the inflation is completed, the gas pressure in the pipeline is detected. When the detected value fluctuates continuously or there are other possible air leaks, a warning is given to prevent insufficient airtightness.

[0034] Furthermore, the bottom end of the internal end of the gastric tube body 2 is an elliptical end, which effectively prevents the gastric tube from causing damage to the patient's pharynx and esophagus when entering the patient's body, thereby improving the safety of the gastric tube.

[0035] Furthermore, the injection device 1 is provided with a leak-proof mechanism, such as a detachable piston.

[0036] Example 2

[0037] Compared with the aforementioned first embodiment, the difference is that, in this embodiment, if a gastric tube with one-way backflow prevention is required, a one-way opening blocking component can be provided on the inner side of the through hole 3 on the side wall of the diversion cavity 6 to prevent the gastric contents from reversely entering and exiting the gastric tube through the channel.

[0038] Furthermore, the blocking component is an elastic valve that opens in one direction toward the closed cavity 5 side.

[0039] In summary, the utility model provides an anti-choking gastric tube, which blocks the gastric tube hole before the gastric tube is removed by providing a double-layer gastric tube and a sealing device, thereby solving the problem of liquid leakage when the gastric tube is removed and improving the safety of the gastric tube.
