Abstract

The invention provides a low-sensitivity medical adhesive plaster, the air permeability of the low-sensitivity medical adhesive plaster is 550-850L / m 2 / S, the tensile shear strength is 24.2-28.8MPa, and the present invention also provides its preparation method. In the preparation of the adhesive layer glue, the required raw materials are 65-95 parts of polymethyl methacrylate, octanoyl 2‑5 parts of glycine, 1‑5 parts of glycidyl methacrylate, 5‑10 parts of N‑isopropylacrylamide, 6‑15 parts of citric acid, 15‑30 parts of silk stock solution, 2‑10 parts of white oil, 5‑10 parts of nanometer zinc oxide. The low-sensitivity medical adhesive plaster of the present invention has antibacterial rates of 99.5-100%, 98.8-99.5% and 96.0-99.9% to Escherichia coli Staphylococcus aureus and Candida albicans respectively; It can automatically wet and fit, has good biocompatibility, and there is no residue on the adhesive surface when it is torn off.

Description

technical field [0001] The invention belongs to the technical field of medical devices and relates to a low-sensitivity medical adhesive tape, in particular to a low-sensitivity medical adhesive tape and a preparation method thereof. Background technique [0002] Adhesive plaster is the most widely used tool in surgical operations. It is suitable for central disinfection supply rooms, operating rooms, stomatology, etc., and is also used in various departments and households for daily use. Because of its poor air permeability, it is prone to allergies, and often brings certain pains to patients with allergies. At present, with the rise of high-tech materials abroad, some tapes of this type have been developed and produced, and some of them have been imported domestically. However, due to the high price and limited import quantity, they have not been widely used. [0003] The Chinese patent with the publication number CN108478330A provides an anti-allergic medical tape and it...
