Description
Technical field
The present invention relates to medical instruments field, more specifically a kind of adhesive bandage more particularly to one kind contain graphene oxide
Adhesive bandage of ingredient and preparation method thereof.
Background technology
Adhesive bandage is most common a kind of surgical medicine in people's life.Adhesive bandage also known as " hemostasis plaster ", have only
Blood, protective effect.By an elongated adhesive plaster, the sliver that centre is accompanied by the dipped drug of a fritter is formed.Due to its structure
Limitation, adhesive bandage are only used for the wound emergence therapeutic of fritter, so as to play the role of temporary hemostasis, protect the surface of a wound.
2004, British scientist Geim etc. prepared single-layer graphene with mechanical stripping method, causes to graphene
Research boom.Graphene be by single layer of carbon atom it is tightly packed into the carbonaceous material with two dimensional surface honeycomb crystal lattice structure
Material, unique nanostructured determine it with a series of excellent performances.Graphene oxide is the important derivatives of graphene,
Its structure is essentially identical with graphene, still remains layer structure, but many oxygen-containing functional groups are introduced on its lamella, such as
Carboxyl, hydroxyl, epoxy group and carbonyl etc., by solvent stripping or hot soarfing from obtained single layer structure, referred to as graphene oxide.
It, can due to the introducing of oxygen-containing groups a large amount of on surface and edge as the monolayer material stripped down from graphite oxide
It is stabilized in aqueous solution and polar solvent.
The type of adhesive bandage is various currently on the market, but the effect of existing most of adhesive bandage hemostasis shield sore and unknown
It is aobvious:If Chinese patent 201310635082.2 discloses a kind of preparation method of pearl powder adhesive bandage, although disappearing with certain
Inflammation hemostasis, healing up sore and subduing swelling and other effects, but effect is unsatisfactory, and slowly effect;Patent 201210275303.5 discloses one kind
Adhesive bandage of the ingredient containing Khotan jade and preparation method thereof is still substantially Chinese herbal medicine class, though there is certain hemostasia and dissipation blood stasis,
But slowly effect, it needs to use for a long time.
Adhesive bandage is generally mainly made of plain cloth adhesive plaster, water absorption pad, protective layer, and water absorption pad is the most important composition of adhesive bandage
Part is made generally by with hemostasis, anti-inflammatory, sterilized pharmaceutics hybrid process on domestic market, though its treatment effect
Also very significantly, but its duration, durability are less desirable for fruit, and the present invention, which has studied, a kind of uses graphene oxide as ingredient system
Into adhesive bandage can solve problems.But it through retrieval, at home, outer does not find to be configured to for ingredient using graphene oxide
Adhesive bandage product and technology.
