Background technique

Clinically, patients cannot eat on their own due to many reasons (including traumatic brain injury, stroke, Parkinson's disease, coma, dysphagia, patients during tumor radiotherapy and chemotherapy, etc.), and a nutrition tube needs to be placed to ensure the nutrition needed for their daily metabolism and disease recovery (i.e. nasal feeding). However, during the indwelling process, catheter displacement and blockage are prone to occur, and gastric juice refluxes into the esophagus, intestinal juice refluxes into the gastric cavity, etc., so the feeding tube needs to be replaced regularly (repeated intubation may damage the throat and esophageal entrance mucosa). Gastroesophageal reflux can lead to a series of adverse consequences, the most important of which are reflux pneumonia, lung infection, and aggravated disease. In order to avoid gastroesophageal reflux, medical staff have also tried to adopt some treatment methods, such as reducing the diameter of the gastrointestinal tube, placing the patient in a semi-recumbent position, increasing digestion-promoting drugs, performing gastrostomy surgery, and changing the nasogastric tube to Nasojejunal and nasoduodenal tubes, etc. However, not only did not achieve the desired effect, but also produced some new complications. For this reason, there is an urgent need for a nutritional tube that can prevent displacement and reflux, which can effectively reduce complications caused by indwelling the nutritional tube and reduce the workload of medical care personnel.
