Degradable wound dressing preparation method and burdening equipment for dressing

Abstract

The invention relates to the technical field of preparation of wound dressing supplies, in particular to a degradable wound dressing preparation method and burdening equipment for dressing. The degradable wound dressing comprises an outer film adhesive layer, a dressing layer and a protective film which are sequentially arranged from inside to outside; a plurality of circulating holes are formed in the middle section of the dressing layer; the bottoms of the circulating holes penetrate through the bottom of the dressing layer; a plurality of drug feeding channels are formed in the middle layerof the thickness of the dressing layer; and a drug feeding hose is glued in each drug feeding channel. The dressing is prepared by adopting a degradable material, a product is more environmentally friendly, can exert good auxiliary wound healing effect in the using process, is breathable while effectively exerting the waterproof protective effect at the same time without oxygen deficiency at a wound, and the healing effect can be guaranteed; and in addition, in the preparation process of the dressing, the burdening equipment can effectively improves the burdening and stirring effects in the preparation process, and the forming quality of a later-stage finished product is effectively improved.

Description

technical field [0001] The invention relates to the technical field of preparation of wound dressings, in particular to a method for preparing a degradable wound dressing and a batching equipment for the dressing. Background technique [0002] A wound dressing is a wound dressing, a material used to cover a sore, wound or other damage. The traditional wound dressing is composed of outer membrane, polyurethane foam, artificial rubber, additives, sodium carboxymethylcellulose absorbent, and glycerol ester adhesive; it can form a soft colloid with wound exudate to promote wound healing. Heals in moisture. [0003] However, existing wound dressings are prone to suppuration or inflammation of the wound when the wound is wet when the wound is healed due to its own structure, material components and preparation process. Although there are also waterproof dressings now, they are waterproof. Type dressings can cause the wound skin to suffer from hypoxia due to its material and stru...

Problems solved by technology

[0003] However, existing wound dressings are prone to suppuration or inflammation of the wound when the wound is wet when the wound is healed due to its own structure, material components and preparation process. Although there are also waterproof dressings now, they are waterproof. Due to the lack of material and structure of the type dressing, it will cause hypoxia of the wound skin while being waterproof, resulting in slow recovery and poor use effect
