Description

An improved gastrointestinal nutrition tube connection device and nasal feeding method thereof

technical field

The invention relates to the technical field of medical devices, in particular to an improved gastrointestinal nutrition tube connection device and a nasal feeding method thereof.

Background technique

At present, for critically ill patients in the ICU, those who need gastrointestinal decompression before and after major surgery, those who cannot eat, those who are comatose, those who are in a vegetative state, those who are bedridden for a long time and cannot eat on their own, and those who have undergone major oral surgery, often need to use a nasal feeding tube for gastrointestinal surgery. internal nutrient supply. There are many methods of nasal feeding. The more commonly used methods in clinical practice are the slow injection of nasal feeding nutrient solution by using a syringe in batches, and the continuous infusion of nasal feeding nutrient solution by using a nutritional pump. Although fractionated nasal feeding is simple and easy to operate, it is easy to cause complications such as reflux or aspiration. Continuous pumping of nasal feeding has little irritation to the gastrointestinal tract and is well accepted by patients. It can not only reduce the adverse reactions of the gastrointestinal tract of patients, improve the nutritional status, but also significantly reduce the incidence of lung infection. However, when the nutrient pump tube is connected with the nasal feeding tube, the connection is often not tight, and the joint is loose, which causes the nutrient solution to leak and cause waste and environmental pollution.

Some existing improvements, such as feeding tube connector and nutrition pump tube connector adopt matching Luer lock connector. Allows the nutritional pump tubing and feeding tube to be securely connected without the risk of the joint slipping off during feeding. But there are disadvantages: 1. Because the Luer lock connector is threaded, it may be necessary to twist the nasogastric feeding tube when connecting the nasogastric feeding tube connector with the nutritional pump tube connector, which may cause the patient to feel very uncomfortable or make the nasogastric feeding tube shift. ②The Luer lock connector for gastrointestinal nutrition is easy to be confused with the Luer lock connector for intravenous administration. If the two are misused, it will cause great harm to the patient.

Some existing improvements, such as designing the connector of the nasal feeding tube as a funnel, designing the connector of the nutrition pump tube as a trapezoidal joint with different diameters, according to the different diameters of the funnel joint, the trapezoidal joint is in contact with the section and joint of the same diameter, It is fixed by the friction force between the two parts. The disadvantages are: ① With the aging of the material and the change of the geometric shape, the connection force will decrease, and when using the nutrient solution containing oil, the connection force will also decrease due to the lubrication effect, and there is a risk of slipping of the connection part . ②If the connector is tightly connected, when the nasal feeding is stopped, a greater force will be used to pull out the nutrition pump tube, and the nasal feeding tube may be pulled out and displaced.

Moreover, the general gastrointestinal feeding tube connecting device has a complex structure, and the operation steps of installation and disassembly are cumbersome and difficult to disassemble.
