Description

Medical hydrogel application capable of fixing drainage tube

Technical Field

The utility model relates to the technical field of medical application, in particular to a medical hydrogel application capable of fixing a drainage tube.

Background

At present, a plurality of patients often need to place a drainage tube at a wound after performing a surgical operation, and the drainage tube needs to be fixed after being placed. The fixed main drainage tube that is conventional is fixed subsides of drainage tube, directly uses the sticky tape to fix or twines again on the drainage tube after using the operation line to pass patient's skin and fix the drainage tube, but the fixed subsides of drainage tube complex operation, the fastness and the aesthetic property of sticky tape are relatively poor, and some patients still probably are allergic to the sticky tape, lead to the drainage tube fixed not good, have the risk of deviate from even. Although the drainage tube fixed by the operation wire cannot be pulled out, the drainage tube is pulled out easily when being pulled, so that the drainage is not smooth, even the phenomenon of slipping occurs, thereby affecting the treatment of diseases and increasing the pain of patients. And the sterile patch is used for pasting the open gauze, so that the drainage tube is stuck to the adhesive layer of the patch, and is easy to collapse or fold, so that the drainage tube is not smooth in drainage, and the recovery of the illness state of a patient is seriously influenced.

Traditional wound dressings, such as bandages and gauze, while effective on wounds that dry to light, exuding, require periodic replacement and cause pain when the dressing is replaced. In addition, their poor adhesive properties do not provide a sufficient drainage hydrogel dressing for wounds, which is one of the most attractive and promising wound dressings due to its comparable moisture retention, biocompatibility and therapeutic properties. The hydrogel dressing commonly used at present is alginate, gelatin, carboxymethyl cellulose and the like, and the dressing can only act on wounds with little exudates because of the general capability of absorbing the exudates, but for wounds with more exudates, the exudates which cannot be absorbed can not maintain a sterile environment to be infected secondarily, and healing is never delayed and complications are caused.
