Device and method for clinical enteral nutrition temperature control

Abstract

The invention discloses a device and method for clinical enteral nutrition temperature control. Nutrient solution in a nutrient solution bag and an infusion tube is respectively heated through a heating bag and a heating tube, temperature measurement is respectively performed on the nutrient solution in the bag and the tube through a first temperature sensor and a second temperature sensor, temperature control is respectively performed on the heating bag and the heating tube according to the measured actual temperature through an automatic temperature controller, the temperature of the nutrient solution in the bag is always maintained at 22-24 DEG C, the nutrient solution is prevented from going bad, the temperature of the nutrient solution flowing through the nose entering position reaches 39 DEG C, the temperature of the enteral nutrient solution entering noses of patients is always at a clinical required temperature on the conditions that nutritional ingredients of the enteral nutrient solution are not damaged, the patients are comfortable when undergoing treatment, the adverse effects are reduced, and absorption of the nutrient solution in intestines of the patients is promoted.

Description

technical field [0001] The present invention relates to the temperature control technology of enteral nutrition liquid, more specifically, relates to a clinical enteral nutrition temperature control device and method. Background technique [0002] Enteral nutrition (EN) is to insert a nasal feeding tube into the stomach or intestines through one side of the nasal cavity, oral cavity or gastroenterostomy, and drip elemental diet or liquid diet from the tube to ensure that patients can consume enough protein. Clinical treatment with heat. Due to the reduced tissue repair ability of the elderly, the recovery time of gastrointestinal motility after surgery or injury is correspondingly prolonged. Therefore, more and more elderly patients are receiving enteral nutrition support in the acute phase of hospitalization. Some studies have reported that the gastrointestinal reactions of enteral nutrition are related to the temperature of the nutrient solution. Especially for Chinese pe...

Problems solved by technology

However, since the intensifier can only be clamped on a small section of the infusion tube, it can only heat the clamped section, and the length of the infusion tube is relatively long, so only heating at a certain small section will exist. The following defects:

[0004] 1. It is impossible to effectively control the proper temperature of the nutrient solution entering the nose, that is, if the sandwiched warming position is far away from the nostril, the nutrient solution entering the nostril has become cold, and when the sandwiched warming position is close to the nostril, it will enter the nostril The nutrient solution inside may be too hot, and the high temperature of the warmer itself will increase the risk of skin burns of the patient;

[0005] 2. Only the heating temperature of the intensifier is limited, but there is no actual measurement of the temperature of the nutrient solution, so the actual temperature of the nutrient solution cannot be effectively controlled;

[0006] 3. The nutrient solution in the tube is in a flowing state, and only a small section of the infusion tube is heated, and the heating effect is not good, and the required temperature cannot be reached;

[0007] 4. The warming position of the sandwich is operated entirely by human experience, which is relatively random, making it even more difficult to uniformly and reasonably control the temperature of the nutrient solution entering the nose
