Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a combined nasointestinal tube component. Background Art

[0002] During the treatment of critically ill patients, patients are unable to eat orally on their own due to their critical condition. In clinical practice, nasogastric feeding is routinely performed through an indwelling gastric tube. Most patients often fast due to the stress of the disease itself or gastrointestinal dysfunction. Prohibition of gastrointestinal feeding often causes insufficient nutritional supply for patients. During hospitalization, body mass index decreases, subcutaneous fat consumption and thinning occur, which reduces their own immune capacity. In addition, some patients experience complications such as vomiting, aspiration into the lungs, and aggravated lung infections due to gastric retention and changes in intracranial pressure, which delays the prognosis of the disease and increases the length of hospital stay and hospitalization costs. In order to prevent gastric retention and vomiting in patients, increase the tolerance and absorption of enteral nutrition in patients, feeding through a nasogastric tube improves the nutritional status of patients, improves their immunity, accelerates recovery, and improves their prognosis and quality of life.

[0003] In the prior art, nasogastric tubes are usually of one-piece structure. In actual use, the length of the nasogastric tube cannot be adjusted by disassembling the tubes from each other, which makes it extremely inconvenient to use. However, if the nasogastric tubes are combined and disassembled, the connection may be unstable. If they fall off and remain in the patient's body, they will cause secondary damage to the patient. At the same time, the nasogastric tube can be visualized during the indwelling process, which greatly facilitates the installation and indwelling of the nasogastric tube.

[0004] In view of this, it is urgent to design a combined nasointestinal tube assembly, which can realize the shaft sealing of the nasointestinal tube by mutually threading the single components of the nasointestinal tube, and the endoscope assembly can be detached from the end of the single component, and the endoscope assembly is connected to the external controller through an optical fiber, and is synchronously retained in the patient's body with the feeding of the nasointestinal tube. The nutrient solution is input and discharged through the input holes on both sides of the nasointestinal tube assembly. Utility Model Content
