Abstract:
Difficulty in swallowing is a common symptom in stroke patients, and nasogastric tubes are routinely used to solve the nutritional support problem of these patients. The existing nasogastric tube have the disadvantages of causing aspiration pneumonia and patient discomfort. The traditional transoral gastric tube has no one-way valve switch and gastric content storage device, and cannot be fixed in the stomach, resulting in reflux of gastric contents, inability to fully understand the digestion and absorption of gastric contents, and accidental dislocation of the gastric tube, affecting further feeding and gastric content detection. For these reasons, the medical staff of the department of gastroenterology and colorectal surgery of Jilin University China-Japan Union Hospital designed a new transoral gastric tube that can extract and store gastric contents, and was granted a national utility model patent of China (ZL 2020 2 1704393.1). The device consists of collection, cannula and fixation modules. The collection module includes three parts. Gastric contents storage capsule, which can clearly visualize the gastric contents; three-way switch, which can be controlled by rotating the pathway, makes the pathway exist in different states, which is convenient for medical personnel to extract gastric juice, as well as perform intermittent oral tube feeding on the patient or close the pipeline, and reduce contamination and prolong the service life of the gastric tube; one-way valve, which can effectively avoid the contents of the reflux back into the stomach. The tube insertion module includes three parts. A graduated tube, which can enable the medical staff to effectively identify the insertion depth; a solid guide head, which makes the insertion of the tube through the mouth more smoothly; the gourd-shaped passageway, which effectively avoids the blockage of the tube. The fixation module is a water-filled balloon, which is properly filled with water and air. After the pipe is inserted through the mouth, it can be injected with water and gas properly to avoid accidental withdrawal of the gastric tube. Intermittent oroesophageal tube feeding of patients with dysphagia after stroke through a transoral gastric tube that can extract and store gastric contents can not only accelerate the recovery process of patients and shorten the hospitalization time, but also transoral enteral nutrition can effectively promote the recovery of patients' systemic systems, which has certain clinical use value.
