Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of medical instruments, and in particular relates to a food syringe. Background Art
[0002] In clinical medical care, gastric tube insertion provides an important means of nutritional support for patients who are unable to eat independently. Infusing liquid food, water and medicine into the patient's body through the gastric tube can effectively maintain the patient's nutritional needs and treatment needs. It is especially suitable for patients in special circumstances such as coma, oral surgery, and refusal to eat. However, in actual application, the use of gastric tubes also faces a series of challenges. One of the most significant problems is the potential harm to patients caused by gastric tube blockage caused by food residues and improper food temperature. First of all, food residue is one of the main causes of gastric tube blockage. Since the food required by patients often needs to be ground or specially processed to ensure that it is in a liquid state without residue, in actual operation, During the feeding process, it is inevitable that some larger food residues will be mixed in. These residues are easy to accumulate in the tube cavity when passing through the gastric tube, and gradually form blockage over time, affecting the smooth infusion of food, and may even cause insufficient nutritional intake for the patient, affecting recovery of the disease. Secondly, food temperature that is too high or too low will have an adverse effect on the patient's condition. Excessively high food temperature may scald the patient's digestive tract mucosa, causing pain, inflammation and even ulcers, while excessively low food temperature may irritate the gastrointestinal tract, causing discomfort to the patient, and even leading to gastrointestinal dysfunction. Although there are some solutions in the existing technology, such as regular flushing of the gastric tube and the use of anti-blockage gastric tube design, these methods often have the disadvantages of cumbersome operation and limited effect.
