Abstract

The invention discloses a preparation method of hydrogel dressing containing honey. The preparation method comprises the steps: evenly mixing a gel stock solution with honey according to a certain proportion, adding a photoinitiator, pouring mixed liquid into a mould to be formed and curing through ultraviolet light to obtain a gel sheet. The hydrogel dressing containing honey disclosed by the invention can quicken a liquid absorption speed of hydrogel, can improve a liquid absorption amount of the hydrogel and can make the hydrogel have a good treating effect on infected wounds.

Description

technical field [0001] The invention belongs to the technical field of medical dressings, and in particular relates to a preparation method of a honey-containing hydrogel dressing. Background technique [0002] In medical clinics, hydrogel plays an important role because of its special properties. Hydrogel contains a lot of water. When the wound is dry, it can provide moisture to the wound. When the wound exudates, the hydrogel can Absorbs exudate and maintains a moist healing environment for the wound. Usually, hydrogel contains a lot of water, generally more than 50%, which determines that the speed of hydrogel absorbing exudate will be slower than other wet dressings. The curative effect is poor, and the growth of bacteria in the wound cannot be inhibited, which is a shortcoming of the current clinical use of hydrogels. [0003] The existing hydrogel uses polyvinyl alcohol as the main raw material, and is mixed with other auxiliary materials and water to make a viscous ...
