Description

Catheter fixing patch

Technical Field

The utility model relates to the field of medical appliances, in particular to a catheter fixing patch.

Background

The deep vein catheterization is mainly used for establishing an infusion path for severe patients, long-term parenteral nutrition, hemodialysis pipelines and tumor chemotherapy.

At present, the fixing mode of the deep vein catheter is mainly clinically implemented in the following two modes: the adhesive tape is adopted to directly bond and fix the catheter, the non-invasive operation is adopted, but because the adhesive tape is adopted to fix, the adhesive tape is softer in material quality, and the catheter is easy to deform and distort due to external force after the adhesive tape bonds the catheter, so that the fixing firmness degree of the catheter is weaker, the catheter is easy to move left and right to break away, and the risk that the pipeline breaks away is easy to cause if negligence and improper operation occur during nursing of staff and accompanying staff.

For this reason, another method of fixing the catheter is mainly used in clinic, in which the deep vein catheter is fixed by suturing and the deep vein catheter is cared by using a transparent application and a combination tape. The method is the most common method in clinic at present, has the advantage of firm fixation compared with the first fixation method, but the method involves the operations of catheter fixation suture, later suture removal and the like, and is troublesome to operate. And this method is an invasive procedure and is prone to catheter-derived infections.
