AI Technical Summary

Technical Problem

In existing technologies, after hemodialysis, the fixation methods for temporary venous catheters and long-term deep venous catheters are loose, making them prone to falling off, increasing the risk of infection, and the operation is cumbersome.

Method used

A visually integrated dressing for fixing hemodialysis catheters has been designed, which includes a bundle, positioning, binding and limiting mechanism. It uses transparent material and cotton core, and fixes the catheter through multiple layers of patches and adhesive, simplifying the operation process.

Benefits of technology

It effectively prevents catheter dislodgement, reduces the risk of infection, simplifies the operation process, improves patient comfort, and facilitates medical staff to observe the catheter position and the condition of the surrounding skin.

Abstract

The utility model relates to the technical field of hemodialysis, and particularly discloses a visible integrated application for fixing a hemodialysis catheter, which comprises a double-folding patch, and a tube bundling mechanism for limiting the position of the hemodialysis catheter is arranged on one side of the double-folding patch. The device at least has the following beneficial effects that the position of the catheter can be effectively and firmly fixed by arranging the tube bundling mechanism, the positioning mechanism, the limiting mechanism and the binding and covering mechanism, so that the possibility that the catheter falls off is prevented, the risk of catheter infection is reduced, and the device belongs to a disposable product and is convenient to use. The whole operation and use process is simpler, the workload of medical staff is relieved, the comfort degree of the skin of a patient during use is improved, the catheter fixing device is mostly made of transparent materials, and the medical staff can conveniently observe the conditions of a catheter opening and the surrounding skin during use.
