Description

Technical Field

[0001] The utility model belongs to the technical field of medical devices, and in particular relates to a connector for enteral nutrition infusion. Background Art

[0002] Enteral nutrition refers to a method of injecting some nutrient solutions that only require chemical digestion or can be absorbed without digestion into the patient's gastrointestinal tract through a gastrointestinal tube or stoma to provide the nutrients needed by the patient. Enteral nutrition can directly input small molecules of nutrients into the intestines, which are directly absorbed and utilized through the intestinal wall, helping to protect the normal physiological function of the intestinal mucosa, restore the patient's damaged intestinal function more quickly, and ensure the coordinated balance of the intestinal flora to the greatest extent, thereby strengthening nutrient absorption to provide energy for the patient, thereby improving the patient's immunity, preventing the occurrence of related infections, and accelerating recovery from the disease. There are two ways of enteral nutrition: oral and transcatheter. Transcatheter delivery includes nasogastric tube, nasoduodenal tube, nasojejunal tube and gastrojejunostomy tube.

[0003] In the prior art, the temperature of the nutrient solution bag is often low during infusion, and low nutrient solution temperature can easily cause complications such as diarrhea. Traditional enteral nutrition infusion devices cannot heat the nutrient solution. Currently, there are some enteral nutrition infusion devices with heaters, but such devices are relatively complex in structure, expensive, and inconvenient to use.

[0004] In addition, most of the nutrient solutions commonly used in clinical practice are powdered rice paste that is cooked by oneself or mixed with boiling water. There may be residual large particles of rice paste, vegetable residues, or incompletely dissolved lumps of rice paste flowing into the infusion tube with the liquid, which will not only cause blockage of the infusion device, but also pose certain safety hazards.

After heating for a certain period of time, turn on the drip rate controller, let the nutrient solution flow down, enter the gastric tube or jejunal tube through the infusion connector, and observe the temperature of the nutrient solution through the thermometer. If the temperature is too low, continue to heat it. If the temperature is too high, disconnect the power supply of the heating mechanism or directly take out the heating mechanism so that the nutrient solution is no longer heated.
