Description

A multifunctional nasal feeding tube and nasal feeding system

technical field

The utility model belongs to the field of medical appliances, in particular to a multifunctional nasal feeding tube and a nasal feeding system.

Background technique

Enteral nutrition support refers to a treatment method in which a nasal feeding tube is inserted into the gastrointestinal tract through one side of the nasal cavity, oral cavity, gastrointestinal stoma, etc. for artificial feeding to ensure that the patient can absorb enough nutrients such as protein and calories. Nutrient factors input through the nasogastric tube enter the liver through the portal vein, which can promote the recovery of intestinal function, improve the nutritional status of the body, and effectively shorten the course of treatment for the disease.

Enteral nutrition support via nasogastric tube is convenient and effective, and has been recognized by clinicians all over the world. However, problems such as hyperglycemia and stress ulcers may occur at the same time. One of the most serious complications is aspiration. Aspiration refers to the entry of variable amounts of liquid contents or secretions into the airway below the glottis, leading to acute lung injury or infection, and even suffocation or death of the patient. It often occurs during nasal feeding nutritional support treatment .

With the wide application of enteral nutrition support by nasal feeding tube in clinical treatment, foreign scholars reported that the incidence of aspiration caused by gastric reflux has risen to 30.5%-40.8%. The stomach-lung infection route caused by reflux aspiration has become the main cause of related pneumonia, which often endangers the lives of patients. The main mechanisms are: 1. The refluxed gastric juice can directly corrode the airway, respiratory tract and alveolar epithelial cells to cause chemical inflammation. When the body's immunity is weakened, it is easy to cause infectious airway inflammation and severe pneumonia. 2. Aspiration caused by a relatively large amount of gastric content can pass through the stomach-esophagus-airway-pulmonary route, resulting in blockage of the bronchi with multiple lungs, and causing lung abscess, respiratory failure, and even suffocation.

Therefore, it is of great significance to design a nasal feeding tube with multiple functions, which can reduce the incidence of various complications during use.
