Lavage device for children digestive system department

Abstract

The invention relates to the technical field of medical instruments. The invention aims to provide a lavage device for the children digestive system department, which comprises a lavage tube used for penetrating into the rectum. The lavage tube comprises an inner tube and an outer tube which are connected in a sleeved mode. The head end of the outer tube is a closed end, and the tail end of the outer tube is an open end; the head end and the tail end of the inner pipe extend out of the outer pipe, the head end of the inner pipe is used for being connected with a liquid filling mechanism, and a silica gel head is arranged at the tail end of the inner pipe; a side connector is arranged on the side wall, close to the head end, of the outer pipe and used for being connected with a liquid drainage mechanism. The lavage device can realize continuous lavage of the rectum, is large in cleaning area, can perform annular flushing, reduce lavage dead angles, and can greatly improve the lavage efficiency.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a lavage device for children's gastroenterology. Background technique [0002] Rectal lavage device is an auxiliary device widely used in gastroenterology. Its main function is to clean the rectum before performing surgery, drug application and other treatment methods. The simplest lavage device in the traditional way is a syringe. Doctors and nurses The staff installs an enema tube on the syringe, then extends the enema tube from the anus into the rectum, pushes the syringe to release the cleaning solution, and then cleans the rectum, but this method is only suitable for extremely simple lavage operations. It is too ineffective when a thorough irrigation of the rectum is required. [0003] For this reason, in the prior art, there have also been some lavage devices, which are provided with a lavage tube extending into the rectum, and a plugging head for blocking the anus...

AI Technical Summary

Problems solved by technology

[0004] However, because this method uses intermittent and alternating liquid delivery and discharge, the overall cleaning efficiency is still limited; at the same time, due to the small flushing surface of the conventional irrigation tube inside the rectum, it is impossible to achieve no dead ends in the true sense Lavage, which is also a major shortcoming of existing irrigation devices
