Nutrient solution conveying device for esophageal cancer

Abstract

The invention relates to the technical field of medical equipment, in particular to a nutrient solution conveying device for esophagus cancer. The nutrient solution conveying device for the esophagus cancer comprises a gastrointestinal tube, an infusion tube, a nutrient solution feeding mechanism, a heating tube sleeve and a temperature sensor, the infusion tube comprises a liquid inlet end and a liquid outlet end, the gastrointestinal tube communicate with the liquid outlet end, the liquid inlet end communicates with a liquid conveying opening of the nutrient solution feeding mechanism, the heating tube sleeve is arranged on the infusion tube in a sleeving mode and extends in the length direction of the infusion tube, the temperature of an inner cavity of the heating tube sleeve is gradually increased from the liquid inlet end to the liquid outlet end, the detection end of the temperature sensor is arranged in the inner cavity of the heating tube sleeve. According to the nutrient solution conveying device, the heating tube sleeve with the temperature of the inner cavity gradually rising is arranged on the periphery of the infusion tube in a sleeving mode, so that when the nutrient solution feeding mechanism conveys nutrients into the body of a patient, the heating tube sleeve can heat the infusion tube at a constant speed, power consumption is reduced, and the preheating time is short.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to a nutrient solution delivery device for esophageal cancer. Background technique [0002] Patients with esophageal cancer cannot normally eat through the esophagus and need enteral feeding with nutrient solution. Therefore, it is necessary to deliver gastrointestinal nutrient solution to the patient's stomach or intestines through a gastrointestinal tube to ensure that the patient can consume enough protein and calories. [0003] Most of the existing technologies use infusion tubes or syringes to pressurize the delivery of enteral nutrient solution. Due to the long operation time of artificial enteral feeding, the nutrient solution will stimulate the patient's intestinal tract after cooling, which will easily cause abdominal distension, abdominal pain, nausea, vomiting and diarrhea. and other complications, and the existing delivery device is only provided with a heater ...

AI Technical Summary

Problems solved by technology

[0006] Based on this, it is necessary to address the existing technical problems and provide a nutrient solution delivery device for esophageal cancer, which solves the problem of long warm-up time and power failure of the existing heating tube through the heating sleeve whose inner cavity temperature gradually increases along the length direction. The problem of high consumption
