Special nutrient solution injection device for department of pediatrics

Abstract

The invention discloses a special nutrient solution injection device for the department of pediatrics. The special nutrient solution injection device comprises a heating cavity containing water, a syringe penetrating through the heating cavity in a sealed manner as well as a heating device and a temperature sensor which are arranged in the heating cavity, wherein the syringe comprises a syringe body, a piston arranged in the syringe body and a piston rod with one end connected with the piston and the other end extending out of the syringe body; a liquid outlet is formed in the front end of the syringe, a liquid outlet switch is arranged at the liquid outlet, the piston rod is driven by a servo motor through a transmission device to move in the axis direction of the syringe body, the servo motor is connected with a PLC (programmable logic controller) through a servo driver, and the heating device and the temperature sensor are connected with the PLC. The device can accurately control the infusion speed and can preheat a nutrient solution when the temperature is lower, so that the discomfort caused to a children patient when the nutrient solution is transfused into the stomach of the children patient is avoided.

Description

technical field [0001] The invention is a special nutrient solution injection device for pediatrics, which belongs to the technical field of medical instruments. Background technique [0002] Clinically, it is necessary to provide nutrition to critically ill children or children with dysphagia, and gastric tube insertion and nasal feeding are one of the commonly used methods. At present, the medical staff hang the infusion bag containing the nutrient solution on a high place, and then communicate with the gastric tube through the infusion tube. Although the purpose of delivering the nutrient solution to the stomach of the patient can be achieved, there are two problems as follows: 1) It is impossible to accurately control the input speed of the nutrient solution. If the speed is too fast, it will exceed the tolerance of the stomach of the child and cause discomfort to the child; If the temperature of the nutrient solution in the lower part is low, it will also cause discomf...
