Preparation method of degradable wound dressing and batching equipment for the dressing

Abstract

The invention relates to the technical field of preparation of wound dressings, in particular to a preparation method of a degradable wound dressing and a batching device for the dressing, comprising an outer film adhesive layer, a dressing layer and a protective film sequentially arranged from the inside to the outside. The middle section of the dressing layer is provided with a number of circulation holes, the bottoms of the circulation holes all pass through the bottom of the dressing layer, and a number of dosing channels are arranged in the middle section of the thickness of the dressing layer. Dosing hose. The dressing is made of degradable materials. The product is more environmentally friendly. It can play a good role in assisting wound healing during use. At the same time, it can effectively play a waterproof and protective role, and at the same time breathable, so as not to cause hypoxia at the wound. The healing effect can be guaranteed; in addition, in the preparation process of the dressing, the batching and stirring effects in the preparation process can be effectively improved by the batching equipment, and the quality of the finished product in the later stage can be 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...

[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
