Description

Disposal sterilized operation drainage catheter

Technical field

This utility model relates to a kind of clinical operation assistant product, is specifically related to a kind of disposal sterilized operation drain and leads Pipe.

Background technology

The surgical drainage tube kind applied clinically is a lot, have for urethral catheterization, have for wound, thoracic cavity, encephalocoele, stomach Intestinal, biliary tract etc. have application.Surgical drainage is in order that being directed to the pus gathered between tissue or in body cavity, blood, liquid External, prevent postoperative infection and affect wound healing.But the tank body of current drainage catheter is mostly dual-end knot Structure, in drainage process, drainage tube end easily produces suction and causes human soft tissue injury, and the drain of existing drainage tube Effect is undesirable, and drainage tube is susceptible to breakage phenomenon.

Utility model content

This utility model provides a kind of disposal sterilized operation drainage catheter, causes people with solve that prior art exists The problem that body soft tissue injury, drainage effect be undesirable and drainage tube easily snaps off.

This utility model solves its technical problem and be the technical scheme is that

A kind of disposal sterilized operation drainage catheter, is made up of drain outer tube, drain inner tube and flush pipe, and drain inner tube is put In drain outer tube, the outer tube endcapped of drain outer tube, drain inner tube end arranges some pod apertures, drain outer tube wall Spiral arranges some circular holes, and the tube wall of flush pipe is attached on drain outer tube wall in the shape of a spiral, the distal opening of flush pipe with Drain outer pipe bottom communicates.

The Spiral distribution circular hole of drain outer tube of the present utility model improves drainage effect, and flush pipe spiral is arranged on drain Guan Shang, improves the stability of drainage tube, and the design of drain outer tube endcapped avoids suction and causes the damage of human body soft tissue, There is the advantage that design is ingenious, easy to use and safe and reliable.

Accompanying drawing explanation

With embodiment, this utility model is further illustrated below in conjunction with the accompanying drawings.

Fig. 1 is structural representation of the present utility model；

Fig. 2 is the structural representation of this utility model drain inner tube.

1 drain outer tube, 2 drain inner tubes, 3 flush pipes, 4 circular holes, 11 outer tube ends, 21 pod apertures, 31 distal opening in figure.

Detailed description of the invention

As depicted in figs. 1 and 2: a kind of disposal sterilized operation drainage catheter, by drain outer tube 1, drain inner tube 2 and flushing Pipe 3 forms, and it is internal that drain inner tube 2 is placed in drain outer tube 1, and the outer tube end 11 of drain outer tube 1 is closed, and drain inner tube 2 end sets Putting some pod apertures 21, drain outer tube 1 pipe wall screw arranges some circular holes 4, and the tube wall of flush pipe 3 is attached to drain in the shape of a spiral On outer tube 1 tube wall, the distal opening 31 of flush pipe 3 communicates bottom drain outer tube 1.
