[0017] A temperature sensor 12 is fixedly connected between the base 1 and the syringe 2. A controller 13 is slidably connected to the top of the base 1 and fixed to the bottom of the drive motor 41. The temperature sensor 12 fixed between the base 1 and the syringe 2 is used to detect the temperature of the food inside the syringe 2. When the temperature of the food inside the syringe 2 is too high or too low, the temperature sensor 12 will transmit a signal to the controller 13. At this time, the controller 13 will turn off the drive motor 41 to avoid injecting food at an unsuitable temperature into the patient's body.
[0018] The positioning chamber 3 has sliding grooves 32 on both sides, and the squeezing block 31 is slidably connected to the inside of the positioning chamber 3 through the sliding grooves 32. The sliding grooves 32 on both sides of the positioning chamber 3 are used to allow the squeezing block 31 to slide, so that the sliding grooves 32 can slide inside the positioning chamber 3 to complete the purpose of venting the air inside the esophageal connector and avoid injecting air into the patient's body during nasogastric feeding.

[0020] The positioning chamber 3 has a connection port 34 on one side, which corresponds to the position of the syringe 2. The connection port 34 on one side of the positioning chamber 3 is used to allow space for the esophageal connector, so that medical staff can put the esophageal connector into the interior of the positioning chamber 3. Since the position of the connection port 34 corresponds to the position of the syringe 2, the syringe 2 can be inserted into the esophageal connector that enters through the connection port 34, thus completing the connection between the syringe 2 and the esophageal connector.
[0021] The working principle and usage of this utility model: When medical staff need to administer nasogastric feeding to a patient, the staff can start the drive motor 41, causing the lead screw 4 to rotate. This causes the push-pull block 21 to slide inside the syringe 2, drawing food into the syringe 2. At this time, the staff can place the gastric tube connector into the positioning chamber 3, positioning it inside the two compression blocks 31. By sliding the two compression blocks 31 against each other, the compression blocks 31 will compress and bend the gastric tube connector, thereby sealing it. Then, by horizontal... By sliding the squeezing block 31, the bent part of the squeezing block 31 moves towards the feeding port of the gastric tube connector. Medical staff can slide the driving base 1 into the positioning chamber 3, so that the syringe 2 inside the driving base 1 slides into the feeding port of the gastric tube connector, thus connecting the syringe 2 to the gastric tube connector. At this time, medical staff can start the drive motor 41, so that the drive motor 41 drives the lead screw 4 to rotate. During the rotation of the lead screw 4, the push-pull block 21 will slide, so that the push-pull block 21 will introduce the food inside the syringe 2 into the patient's stomach through the gastric tube, thereby completing the nasogastric feeding.
