Abstract

The invention discloses a chlorhexidine gluconate antibacterial transparent dressing, and relates to the technical field of medical appliances. The chlorhexidine gluconate antibacterial transparent dressing comprises a printing layer, a flexible layer, a adhesive layer, a dressing layer and a protective layer. The surface of the printing layer is adhered to the back of the flexible layer, the adhesive layer is arranged on the surface of the flexible layer, the dressing layer is located in the middle of the surface of the flexible layer, and the back of the protective layer is adhered to the surface of the flexible layer through the adhesive layer. The chlorhexidine gluconate antibacterial transparent dressing has an excellent killing effect on vegetative forms of bacteria on the surface ofthe skin and some viruses and fungi by adding the chlorhexidine gluconate and silver nanoparticles, with little irritation; the dressing has analgesic and anti-inflammatory effects by adding honeysuckle flower extract, paeonol and urocystin; the dressing layer is yellow and transparent, so that the wound site can be clearly observed; and the transparent dressing is good in adhesion to the skin, so that the transparent dressing is convenient to use.

Description

technical field [0001] The invention relates to the technical field of medical appliances, in particular to a chlorhexidine gluconate antibacterial transparent dressing. Background technique [0002] Antibacterial transparent dressing is a transparent dressing used to cover and protect the catheter site and fix various catheter equipment to the skin. It cannot be used on ulcerated wounds or unhealthy skin. Common uses include fixing and covering intravenous catheters, other blood vessels, etc. Catheters and transdermal devices, which can also be used to reduce skin colony counts and inhibit microbial regrowth, are widely used in medicine. [0003] Existing antibacterial dressings cannot have a good killing effect on bacterial propagules and some viruses and fungi on the skin surface, and are highly irritating at the same time. It is complicated, and at the same time, the dressing is opaque, so that the wound site cannot be clearly seen, and it is inconvenient to use. Cont...
