Abstract

The invention discloses a breathable medical bandage and a preparation method thereof. The bandage is composed of the following components in parts by mass: 24-37 parts of polyvinyl alcohol, 10-22 parts of glycerin, 3-11 parts of menthyl acetate, acetyl 8-19 parts of tributyl citrate, 23-39 parts of deionized water, 2-10 parts of glycerin trilinoleate, 1-10 parts of phosphatidylcholine, 4-21 parts of sodium polyacrylate, 6 parts of methyl cellulose -18 parts, 3-17 parts of isopropyl palmitate, 5-19 parts of ethanol. The bandage prepared by the invention can improve the protection time and water vapor transmission rate, achieve the effect of ventilation, and can be widely used in clinical treatment.

Description

technical field [0001] The invention belongs to the field of medical materials, in particular to a breathable medical bandage and a preparation method thereof. Background technique [0002] Medical bandages are common medical supplies, used to fix and protect surgical or injured parts. They are necessary for surgical operations. Side bandages, adhesive plaster bandages, etc. [0003] However, during the use of medical bandages, due to a long time or an increase in the surrounding temperature, there will be airtight phenomena, resulting in reduced protection time and unable to be used normally. Contents of the invention [0004] In order to overcome the deficiencies of the above prior art, the present invention provides a breathable medical bandage and a preparation method thereof. The prepared bandage can improve protection time and water vapor transmission rate, achieve breathable effect, and can be widely used in clinical treatment middle. [0005] The technical schem...
