The arrangement of the connecting tube can guide the gas in the patient's stomach through negative pressure, thereby reducing the pressure in the patient's stomach and reducing the squeezing of the patient's stomach on the device. The arrangement of the guide tube can increase the pressure on the guide tube through the internal air bag and reduce the deformation of the guide tube, thereby reducing the damage to the patient caused by the guide tube when flowing food and increasing the practicality of the device.

[0022] 2. The anti-pressure damage gastric tube can prevent air from entering the device when it is used to absorb food again through the settings of the needle tube and the compressor, thereby preventing air from entering the device and causing discomfort to the patient. The setting of the needle tube can absorb fluid food and inject it into the patient's stomach as needed. The setting of the compressor can close the device through adjustment when the food in the needle tube needs to be absorbed again after injection, thereby preventing air from entering the device and then entering the patient's body and causing discomfort to the patient, thereby increasing the protectiveness of the device.
