Medical sterile foam dressing and preparation method thereof

Abstract

The invention discloses a medical sterile foam dressing which comprises purified water, a waterborne polyurethane prepolymer, a foam stabilizer, a catalyst, an antibacterial agent, honey essence, olive oil, metal powder, a radix angelicae dahuricae extract and a foaming agent. The weight ratio of the above materials is : 200 -300 parts of purified water, 50 -70 parts of an aqueous polyurethane prepolymer, 20 -30 parts of a foam stabilizer, 10 -15 parts of a catalyst, 10 -20 parts of an antibacterial agent, 15 -20 parts of honey essence, 15 -20 parts of olive oil, 5 -10 parts of metal powder, 3 -7 parts of radix angelicae extract and 5 -8 parts of a foaming agent, wherein the ratio of the purified water to the foam stabilizer is 10: 1, and the ratio of honey essence to olive oil is 1: 1. The foam stabilizer is an organic silicon foam stabilizer. According to the sterile foam dressing, the situation that bacteria adhere to the foam dressing can be reduced, the effects of relieving edema and promoting cell growth can also be achieved. Meanwhile, the situation that scars appear after wound healing can also be reduced, the situation that the scars appear after wound healing and affect the aesthetic feeling of the skin is prevented, and the using effect of the sterile foam dressing is improved.

Description

technical field

[0001] The invention relates to the technical field of foam dressings, in particular to a medical sterile foam dressing and a preparation method thereof. Background technique

[0002] Foam dressings can reduce the risk of wound adhesions and promote wound healing. However, there are still some problems in most of the existing foam dressings, such as the polyurethane foam dressing mentioned in the Chinese patent CN108079362A, which can shorten the time of wound healing, but it is not produced in a sterile working room during the production process Work, there may be bacteria attached in the final packaging, which will affect the use effect of the foam dressing. At the same time, this patent has no other effects on wound healing, and its functionality is poor, which cannot meet people's needs. Therefore, we propose a A medical sterile foam dressing and a preparation method thereof are used to solve this situation. Contents of the invention
