Abstract
Description
Technical Field
[0001] The utility model belongs to the technical direction of gastrojejunostomy tubes, and particularly relates to a gastrostomy tube. Background Art
[0002] Percutaneous endoscopic gastrojejunostomy is suitable for patients who are unable to eat orally for various reasons. However, the gastrointestinal tube is corroded by gastric acid over a long period of time, and may gradually harden, crack, and break. Improper daily care can leave food debris in the tube lumen, causing food spoilage, infection, and lumen blockage. Therefore, most gastrointestinal tubes are recommended to be replaced every three to six months to prevent adverse consequences caused by prolonged use. However, in bedridden patients with Alzheimer's disease who require lifelong use of a gastrointestinal tube, a problem arises: the tube is left in place for far longer than the ideal duration of use. While the tube is intact and the skin around the tube is infection-free, there is residual spoiled food debris in the tube lumen outside the skin that cannot be cleaned with saline. To avoid infection and ensure patient safety, the tube must be replaced through multiple invasive surgeries, which imposes a certain financial and physical burden on the patient.
