[0002] For patients who are unable to eat on their own, it is usually necessary to insert a gastric tube to deliver nutrients into the stomach. Due to the patient's condition or body position, nutrients delivered through the gastric tube are prone to food reflux, causing food to accumulate in the esophagus or enter the trachea, causing adverse consequences for the patient.

[0003] At present, the insertion of gastric tubes is mainly carried out by medical staff. During intubation, the tube is usually inserted through the patient's nose or mouth. The patient feels strong discomfort and is prone to fear and rejection, which in turn affects the operation of medical staff, especially for conscious children. In addition, the esophageal-gastric fundus temperature can accurately reflect the patient's core body temperature, which is extremely important for critically ill patients who cannot eat. However, the functions of the gastric tubes commonly used in clinical practice are relatively simple and do not have the function of body temperature monitoring. Therefore, it is urgent to solve the above problems. Utility Model Content

The gastric tube of the utility model also includes a body temperature display screen 5, the body temperature display screen 5 is electrically connected to a temperature probe 6, and the temperature probe 6 is arranged at the bottom end of the suction tube 3. It should be noted that the diameter of the top of the hollow channel 21 should be much larger than the diameter of the suction tube 3, and a certain gap should be maintained to allow the gas to pass smoothly through the through hole 24. The diameter of the temperature probe 6 should also be smaller than the diameter of the suction tube 3, and a certain gap should be maintained to allow the liquid to pass smoothly through the suction tube 3. The temperature probe 6 and the body temperature display screen 5 are connected by a thin wire. The top of the suction tube 3 is integrally connected to the main tube 1 to maintain sealing, and can be manufactured by ultrasonic welding.

[0026] A control valve 7 is provided at the top of the main pipe 1, and the control valve 7 is used to open and close the main pipe 1. The control valve 7 preferably adopts a ball valve, which is convenient for connection to the main pipe 1 and easy to operate. Usually, when the air cavity 23 needs to be inflated or evacuated, the control valve 7 is in an open state, and in other cases it is in a closed state to ensure that the air cavity 23 is closed. The diameter of the main pipe 1 is 0.3-1cm and the length is 80-120cm. The diameter of the main pipe 1 is preferably 0.3cm. The thinner the main pipe 1 is, the easier it is for the patient to swallow it, and it is less likely to cause discomfort reactions such as nausea and coughing, and it is not easy to cause fear and rejection. At the same time, it is necessary to meet the pipe diameter that the gas can pass quickly, and it is preferably made of medical PVC material.

[0027] refer to Figure 3As shown, the limit block 4 is annular, and the inner wall of the limit block 4 is convexly provided with a one-way stop tooth 41, and the cross section of the outer wall at the top of the main tube 1 is serrated; the limit block 4 is provided with a strap 42, and the strap 42 can also be replaced by other connection methods such as medical tape, Velcro, etc. Specifically, the limit block 4 can only move from the inflation connector 11 to the direction of the balloon 2. When moving in the opposite direction, the one-way stop tooth 41 will form a stopper with the outer wall of the main tube 1. Usually, the patient bites the limit block 4, and under the action of the one-way stop tooth 41, the main tube 1 can be prevented from moving into the patient's body to avoid the balloon 2 not sealing the cardia. The strap 42 can also be tied to the patient's head at the same time to further fix the main tube 1. Preferably, the limit block 4 is made of a hard material as a whole, but its surface has a layer of non-slip silicone layer 43, which is convenient for the patient to bite.

[0028] The middle part of the hollow channel 21 is a bellows, and a sealing ring 8 is provided between the outer wall of the suction tube 3 and the inner wall of the bottom end of the hollow channel 21. During the expansion or contraction of the expansion balloon 22, the bellows will be extended or compressed accordingly, and the outer wall of the suction tube 3 and the bottom end of the hollow channel 21 will also slide relative to each other, so that the balloon 2 can maintain a smaller volume in the contracted state, which is convenient for patients to swallow and avoid discomfort.

[0029] The expansion capsule 22 is capsule-shaped in the expanded state, and the top of the expansion capsule 22 is conical; the diameter of the expansion capsule 22 is 0.5-5 cm, and the length is 2-8 cm. Usually, in the contracted state, the diameter of the expansion capsule 22 is 0.5 cm, and the length is 2 cm; and in the expanded state, the diameter of the expansion capsule 22 is 5 cm, and the length is 8 cm.

[0030] A suction interface 31 is provided at the top end of the suction tube 3 , and a sealing cover 32 is connected to the suction interface 31 . The sealing cover 32 is used to open and close the suction interface 31 .

[0031] The specific working principle of the utility model is as follows: the medical staff grasps the top of the main pipe 1, and after the patient swallows the balloon 2, the inflation device is connected through the inflation joint 11. The gas passes through the main pipe 1 and enters the air cavity 23 from the through hole 24. Under the action of the air pressure, the expansion bag 22 is expanded and the hollow channel 21 is extended until the pressure reaches a predetermined value. At this time, the expansion bag 22 is in the maximum expansion state, and the control valve 7 is closed; the medical staff gently pulls the main pipe 1, and can clearly feel that the balloon 2 is blocked by the cardia. At this time, the medical staff pushes the limit block 4 downward to let it reach the patient's mouth, and let the patient bite the limit block 4, and selectively uses the strap 42. At this time, under the action of the one-way stop tooth 41 and the balloon 2, the main pipe 1 is stably restricted in the patient's esophagus, and the balloon 2 effectively seals the cardia;

[0032] On the contrary, by opening the control valve 7 and discharging or removing the gas in the air cavity 23, the balloon 2 will shrink to a conical state, and the gastric tube can be easily taken out of the patient's body.
