Nasal feeding device

Technical Field

The application relates to the technical field of medical equipment, in particular to a nasal feeding device.

Background

For critically ill patients, if the gastrointestinal tract functions well, early enteral nutritional support is recommended, which not only improves the nutritional status of the patient, but also maintains the structural and functional integrity of the patient's intestinal mucosa, promoting recovery from disease.

When a critically ill patient carries out enteral nutrition, complications such as diarrhea, aspiration, high-level stomach residual amount, abdominal distension and the like are easy to occur, the occurrence of the complications can cause the interruption of enteral nutrition, and the interruption of unreasonable feeding can cause the secretion of digestive juice such as gastric acid, bile and the like to be reduced due to the lack of food and the stimulation of gastrin of intestinal mucosa, the sterilizing capability of the intestinal tract is weakened, the propagation and displacement of enterotoxin are increased, and further the inflammatory reaction of the intestinal tract and even the whole body is caused. Among them, diarrhea is the most common complication. In critically ill patients, enteral nutrition-related diarrhea is caused by a variety of factors, depending on the temperature, concentration, and feeding rate of the nutrient solution.

In the prior art, some patients do not tolerate nasal feeding liquid with higher concentration clinically, but the existing nasal feeding device does not have the diluting function of the nasal feeding liquid. In addition, the nasal feeding liquid is clinically heated by using a single heating rod and is unevenly heated, so that the temperature is not constant, the overheated nasal feeding liquid directly contacts the skin and is easy to cause local scald of the skin of a patient, and the nasal feeding liquid with low temperature can cause diarrhea of the patient.
