Description

Nanocellulose band-aid

Technical Field

The utility model relates to the technical field of medical supplies, in particular to a nanocellulose band-aid.

Background

The woundplast is the first choice of the most common medical medicine for emergency treatment in home due to its small volume, simple use, convenient carrying and the like, and has certain requirements on the repair function of wound healing except for being used for stopping bleeding, blocking bacterial invasion, protecting the wound and reducing the occurrence of complications.

The common woundplast is made of non-woven fabric or common adhesive plaster, which has small porosity, poor permeability and low effective utilization rate of transferring medicine materials to the wound surface; poor biocompatibility, redness, itching, swelling and pain of the wound may occur for users with sensitive skin, and ulceration of the wound may occur in overly sensitive wound sites. Therefore, a nano-cellulose band-aid is provided.

SUMMERY OF THE UTILITY MODEL

The utility model provides a nanometer cellulose woundplast, which is insufficient for the prior art, and realizes the effect of accelerating the healing of the wound surface by adopting nanometer cellulose materials. The nano-cellulose has the advantage of large porosity, has better water and air permeability than common gauze dressings, and can effectively utilize the collagen in the dressing with high permeability in the permeation process. On the other hand, the nano-cellulose has the characteristic of biocompatibility and can be used as a high-quality material of biological dressing. The collagen can reach the wound surface from the inside of the band-aid through the nano-cellulose, so that the problems of poor permeability and poor biocompatibility of the common band-aid in the background technology are solved.

In order to achieve the above object, the utility model provides a following technical scheme: a nano-cellulose collagen band-aid. Including band-aids and nanocellulose materials.

A nanocellulose band-aid comprises a band-aid base layer, an adhesive layer arranged in the middle of the band-aid base layer, a collagen layer arranged on the adhesive layer, and a band-aid coating layer positioned on the upper portion of the adhesive layer.

Further, the woundplast basic unit comprises cover bandage and the layer of pasting, and wherein the cover bandage sets up at the bottom, pastes the layer setting and is in the both ends semicircular in shape of cover bandage, sets up waterproof viscose on the semicircular structure.

Furthermore, the adhesive layer is composed of a microporous biological adhesive film with a circular cross section and is used for bonding connection between the woundplast base layer and the coating layer on the premise of certain air permeability.

Further, the area of the collagen layer is smaller than that of the adhesive layer, and the collagen has a biocompatible film which can accelerate the healing of the wound.

Furthermore, the area of the application layer is larger than that of the collagen layer, and the nanocellulose is used for contacting with the wound surface, and the preferable mesopore of the nanocellulose is 2-50 nanometers.

Furthermore, the coating layer comprises a coating layer and a collagen layer, the coating layer is a structure formed by laminating the collagen layer and the coating layer, and the laminated structure enables collagen to better utilize the characteristic of good permeability of the nano-cellulose, so that the collagen is fully contacted with the skin, and the purpose of quickly healing the wound is achieved.

Compared with the prior art, the beneficial effects of the utility model are that: the collagen is natural protein of the body, has larger affinity, weaker antigenicity, good biocompatibility and biodegradation safety to protein molecules on the surface of the skin, and has a repairing effect. The nano-cellulose has the characteristics of high specific surface area, large porosity and strong permeability, and can fully and effectively utilize the material
