Description

Technical Field

[0001] The present invention relates to the technical field of medical auxiliary equipment, and in particular to a nasogastric feeding device for patients with acute and critical illnesses. Background Art

[0002] Intensive care refers to the centralized and intensive treatment and care of all kinds of critically ill patients, using various advanced medical technologies, modern monitoring and rescue equipment. To maximize the survival of patients and their subsequent quality of life. Nowadays, some critically ill patients and malnourished patients need enteral nutrition support, which is usually carried out by delivering liquid nutrients to the intestine through a nasogastric tube. Nasogastric feeding is a technique of inserting a catheter into the stomach through the nasal cavity and infusing food, water and drugs from the tube to maintain the patient's nutritional treatment. For patients who cannot eat orally, liquid food is infused through the gastric tube to ensure that the patient takes in enough nutrition, water and drugs to maintain metabolism, weight and nutrition in the body.

[0003] There are three main problems with existing nasogastric feeding equipment: 1. During continuous nasogastric feeding, the temperature of the nasogastric feeding fluid gradually decreases over time, so that the temperature of the nasogastric feeding fluid cannot reach the required 38-40°C. When the nasogastric feeding patient continues to be pumped in, the temperature of the nutrient solution is too low, which can easily cause complications such as diarrhea in the patient; 2. Nasogastric feeding sometimes needs to last for more than ten hours. When the indoor temperature is too high in summer, the nutrient solution is easy to deteriorate, and it is difficult for medical staff to discover when it deteriorates, and the patient's health cannot be guaranteed.

[0004] In view of the above problems, there is an urgent need for a nasogastric feeding device for critically ill patients that can effectively heat the nutrient solution, avoid causing abdominal pain and diarrhea to the patient, preserve the nutrient solution well, monitor in real time whether the nutrient solution is deteriorating, avoid affecting the patient's health, and is easy for medical staff to operate and use.

[0005] The purpose of the present invention is to provide a nasogastric feeding device for critically ill patients that can effectively heat the nutrient solution, avoid causing abdominal pain and diarrhea to the patient, preserve the nutrient solution well, monitor in real time whether the nutrient solution is deteriorating, avoid affecting the patient's health, and is easy for medical staff to operate and use, with excellent effectiveness, practicality and safety.
