Abstract

The invention provides an adhesive bandage. The adhesive bandage comprises a wound protective cushion and an adhesive backing, wherein the wound protective cushion consists of a nonwoven fabric and a PE partition membrane, and the nonwoven fabric is coated by a medicament and is povidone iodine. The invention also provides a preparation method of the adhesive bandage. With the adoption of the adhesive bandage prepared from the povidone iodine, the cost is controllable, the use and the carrying are convenient, and the adhesive bandage and the povidone iodine can jointly take the functions of antibiosis, hemostasis and wound protection together.

Description

technical field [0001] The invention relates to the field of medical dressings, in particular to a band-aid and a preparation method thereof. Background technique [0002] Povidone-iodine (PVP-I) is a complex of 1-vinyl-2-pyrrolidone homopolymer (PVP) and iodine, containing 9.0% to 12.0% of available iodine, and is a highly efficient, broad-spectrum, non-toxic Bactericides have extremely strong bactericidal power and a wide range of bactericidal spectrum, and can kill bacteria, fungi, viruses, and protozoa. It has reliable bactericidal effect, stable performance, no need for deiodination with alcohol, no irritation to skin and mucous membranes, safe and easy to use, and is widely used for preoperative disinfection of surgical personnel, skin disinfection of injection and puncture sites, and disinfection of mucous membranes and wounds. Povidone iodine will dissociate under high temperature and high humidity conditions, which will affect its antibacterial effect. [0003] Th...
