Embodiment 1

[0021] The medical dressing for promoting wound healing in this embodiment includes the following raw materials in parts by weight: 100 parts by weight of gelatin, 50 parts by weight of sodium alginate, 160 parts by weight of polylactic acid, and 20 parts by weight of mannose.

[0022] Its preparation method is as follows:

[0023] (1) Weigh the gelatin, sodium alginate, polylactic acid, and mannose in parts by weight, and grind the gelatin into powder, mix the gelatin, sodium alginate, polylactic acid, and mannose evenly, and mix the mixture Add it into 1wt% hydrochloric acid solution, stir until it is completely dissolved, then add the emulsifier monoglyceride stearate therein, and mix uniformly to obtain an emulsion;

[0024] (2) The emulsion is subjected to freeze-quenching thermal phase separation at -30°C, and then 1 wt% sodium hydroxide solution is added for reverse phase regeneration, and the obtained precipitate is washed with water and dried to obtain the promoted T...

Abstract

The invention provides medical dressing capable of promoting wound healing. The medical dressing is prepared from the following raw materials in parts by weight: 100 to 200 parts of gelatin, 50 to 100parts of sodium alginate, 80 to 160 parts of polylactic acid and 20 to 150 parts of mannose. According to the medical dressing capable of promoting the wound healing, all the raw materials are high molecular materials with good biological compatibility; the polylactic acid is added, so that the obtained medical dressing has an anti-inflammatory effect and has a good effect of promoting the woundhealing.

Description

technical field [0001] The invention relates to the medical and health field, in particular to a medical dressing for promoting wound healing. Background technique [0002] Wound dressings are wound dressings, materials used to cover sores, wounds or other damage. An important function of modern wound dressings is that they take over the important functions of damaged skin and continue to act until wound healing and skin lesions heal. It protects against mechanical factors (such as dirt, collisions, inflammation, etc.), against pollution and chemical stimuli, against secondary infection, against desiccation and loss of body fluids (loss of electrolytes), against heat loss, in addition to providing comprehensive protection for wounds, It can actively affect the wound healing process through debridement and create a microenvironment that promotes wound healing. [0003] In the treatment and care of skin wounds, medical dressings are one of the must-haves, such as "band-aids"...
