Abstract

The invention discloses an antibacterial dressing used in a hepatological surgery department and relates to the technical field of medical dressings. The antibacterial dressing comprises a fiber layerI, a gel layer and a fiber layer II which are sequentially arranged from inside to outside, wherein the gel layer is made of the following raw materials in parts by weight: 45-55 parts of acrylic acid, 40-50 parts of N-hydroxymethyl acrylamide, 10-20 parts of polyvinyl alcohol, 1-2 parts of dihydroxyaluminum aminoacetate, 3-8 parts of talcum powder, 1-2 parts of a polypropylene fiber, 4-8 parts of sodium carboxymethylcellulose, 5-12 parts of polyvinylpyrrolidone, 0.6-1.2 parts of N,N-methylene bisacrylamide, 0.5-1 part of sodium persulfate and 200-300 parts of water. The antibacterial dressing is excellent in antibacterial property and mechanical property, and is beneficial to rapid recovery of wounds.

Description

Technical field [0001] The invention relates to the technical field of medical dressings, in particular to an antibacterial dressing for hepatobiliary surgery. Background technique [0002] Hepatobiliary surgery is mostly laparotomy. Intraoperative blood loss, long operation time, and postoperative surgical site infection are common complications. The prevention of wound infection after hepatobiliary surgery is very important for the patient’s postoperative recovery. Antibacterial dressings It is a commonly used dressing for postoperative wound care. It is used to stop bleeding or absorb wound exudate. It can be antibacterial and antibacterial and accelerate wound recovery. [0003] The Chinese patent document (publication number CN 105664238B) discloses a preparation method and application of a zwitterionic hydrogel dressing. Mix the zwitterionic monomer, crosslinking agent, initiator, sodium chloride and distilled water according to the above-mentioned component content range. ...
