High-flow anti-blockage drainage pipe

Abstract

The invention relates to a high-flow anti-blockage drainage pipe comprising an outer slotted pipe section, a closed pipe section and a transition section which connects the two pipe sections; the inside of the slotted pipe section is a drainage channel in which radial support bodies divide the cross section of the pipe into N sector areas; the outer wall of the pipe body is provided with N strip-shaped notches which correspond to the sector areas as drainage ports; N ribs which are protruded to an axis are arranged in a closed pipeline; and in the transition section, the ribs are connected with the support bodies, and N is more than or equal to 3. The drainage pipe has high flow, the ribs are arranged in the closed pipeline, and the high-flow anti-blockage drainage pipe has flow capacity and high anti-blockage performance after being bent.

Description

technical field [0001] The invention relates to the technical field of medical catheters, in particular to a large-flow anti-blocking drainage catheter. Background technique [0002] In the drainage catheter in the prior art, the drainage holes are generally circular holes, which are evenly distributed on the inner end of the tube body. When such drainage holes are in contact with human tissue, they are easy to suck human tissue. Chinese patent: 200920167107.X publication A non-transitional deformation medical catheter, the catheter in this patent uses a strip groove as the drainage port, which successfully solves this problem and can minimize the damage to human tissue, and its flow capacity is compared with that of a circular tube. The duct with the shaped hole as the drainage hole has been improved a lot, but the closed section of the duct still has the problem of being easily blocked when it is discounted, and there is still room for improvement in the flow capacity....
