Problems solved by technology

[0004] Although this kind of negative pressure suction device can improve the problem of waste liquid discharge, for the human body, it is difficult to control the negative pressure generated by the negative pressure suction device relying on mechanical devices, making the pressure difference between the intestinal tract and the outside of the body very unstable. The discharge

Embodiment Construction

[0055] The present invention will be further described below in conjunction with the accompanying drawings.

[0056] like figure 1 Shown is a schematic structural view of the irrigation and drainage catheter in the present invention.

[0057] The liquid inlet pipe 2 is inserted into the inner chamber of the waste liquid eluting pipe 1 through the liquid inlet pipe branch pipe 5, and can move axially along the inner chamber. The branch pipe 5 of the liquid inlet pipe is arranged on the outside of the pipe wall of the waste liquid eluting pipe 1 inclined backward. The front ends of the liquid inlet pipe 2 and the waste liquid eluting pipe 1 are respectively provided with several liquid inlet holes 8 and liquid discharge holes 9 .

[0058] The waste liquid separation pipe 1 is provided with a forward-inclining auxiliary pipe 4, and the connection position between the auxiliary pipe 4 and the waste liquid separation pipe 1 has a certain backward movement compared with the liquid...

Abstract

An enemating-draining guide tube with used fluid guiding and draining unit has a used fluid educing-out tube. It features that said used fluid guiding and draining unit arranged on said educing-out tube has the drain aiding holes or branch tubes on the educing-out tube for generating a mass stream in the educing-out tube and in turn a negative pressure for promoting said draining.

Description

technical field [0001] The invention relates to a medical irrigation and drainage device, in particular to a medical irrigation and drainage catheter with a waste liquid guiding device for dialysis and treatment through the human colon. Background technique [0002] Colon dialysis or colon perfusion drug administration through auxiliary perfusion equipment and catheters or special probes inserted into the large intestine through the anus to treat acute and chronic renal failure, liver failure, and acute and chronic ulcerative colitis, bacillary dysentery, food or drug poisoning, The treatment of diseases such as high fever caused by various reasons is being re-recognized and valued by clinicians. Compared with hemodialysis and peritoneal dialysis, it is popular among patients because of its non-invasiveness, no concurrent infection, simple implementation and low treatment cost. However, the existing irrigation and drainage catheters generally rely on the pressure and gravit...
