Large-flow anti-blocking washable drainage catheter

Abstract

The invention discloses a large-flow anti-blocking washable drainage catheter. The groove tube comprises a center tube body and N supporting bodies extending outward in a radial mode along the center tube body. The supporting bodies divide the exterior of the center tube body into drainage channels of N sector regions, outer tube walls are arranged on the exteriors of the supporting bodies, the outer tube walls are provided with N strip-shaped groove openings corresponding to the N sector regions and serving as drainage openings, a plurality of washing holes are formed in the side portion of the center tube body, and the interior of the center tube body and the sector regions are communicated by the washing holes, wherein N is larger than or equal to three. Because the large-flow anti-blocking washable drainage catheter is provided with the center tube body and the washing holes, the large-flow anti-blocking washable drainage catheter has the washing capacity, and the groove tube can be used in places where washing and drainage are needed. The strip-shaped groove openings extend in a spiral mode around the axis of the center tube body, and thus flow capacity of the drainage groove tube, and speed and effects of the drainage can be promoted.

Description

technical field [0001] The invention relates to the technical field of medical catheters, in particular to a large-flow anti-blocking flushable 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...

Problems solved by technology

[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 folded, and there is still room for improvement in the flow capacity

For this reason, our unit applied for the patent of the name: large-flow anti-blocking drainage catheter some time ago, which successfully solved the problem of blockage, but after a period of use, it was found that the catheter does not have the ability to flush and needs to be improved.
