Abstract
The utility model relates to a biofilm compound dressing which is characterized by being composed of a heal-promoting biofilm and a self-adhesion medical dressing pad. The heal-promoting biofilm is a film made by blending and drying water-soluble chitosan and sesame oil, is directly covered on a wound when in use, has moisturizing and antibacterial effects on the wound, has a certain flexibility and strength, integrally forms into gel after absorbing exudate, is not adhered to the wound, is convenient to replace, does not generate secondary damage, and is remarkable in wound healing promoting effect. The self-adhesion medical dressing pad is connected with the heal-promoting biofilm through an adhesive, has the effects of fixing and protecting the heal-promoting biofilm, and can absorb lots of exudate.
Description
Technical field
This utility model relates to a kind of biomembrane combine dressing, belongs to biomedical materials field.
Background technology
Wound is the infringement that normal skin (tissue) causes under the external world causes injury factor effect.For the healing of acceleration of wound, reduce the infection of wound surface, generally adopt the method for dressing covering and protection to treat.Traditional surgical wound dressings is medical absorbent cotton and gauze, it has powerful and absorbs rapidly the ability of wound surface transudate, treatment to wound can be played certain facilitation, but exists the deficiency that can cause with the wound surface adhesion, when changing dressings the wound surface secondary damage.
Desirable medical dressing should possess following performance: (1) keeps the wound surface moist environment, is beneficial to wound healing; (2) can effectively absorb the wound surface exudate, reduce and infect; (3) not only have good permeability, and can effectively intercept the invasion of antibacterial and harmful particle; Can not stick together with wound when (4) removing dressing, in order to avoid cause secondary damage; (5) have antibiotic, antiinflammation, it is convenient, easy to use to store; (6) effects such as hemostasis, pain relieving are preferably arranged, can promote granulation growth and skin regeneration, healing acceleration reduces cicatrix.
The chitosan or derivatives thereof has the effects such as good promoting healing, antibiotic, hemostasis and analgesia, is the focus of developing in recent years biological dressing.The chitosan or derivatives thereof is prepared film forming, sponge or gel preparation, can be used for treating wound surface, but still the Shortcomings part.The gel preparation of chitosan or derivatives thereof has the shortcomings such as absorbing wound exudate is few, the difficulty of changing dressings.And simple chitosan derivatives film preparation or sponge preparation be because of its poor mechanical property, and running into liquid namely dissolves, and the shortcoming such as be unfavorable for changing dressings.Add the product of chemical cross-linking agent after crosslinked so in recent years mostly be at the chitosan that grinds or go on the market and derivant promoting healing product thereof, exist cross-linking agent to the potential risk of body harm.Therefore, chitosan or derivatives thereof and other materials is compound, and being developed to the compound bio medical dressing has become trend.Oleum sesami is the material that China is used for the treatment of scald, burn traditionally, and the Multiple components that it contains all has the promoting healing function, and has nontoxic, wide material sources, and low price uses the advantages such as simple.With the biomembrane for preparing after chitosan or derivatives thereof and the Oleum sesami blend, film toughness is stronger, absorb form the globality gel behind the transudate can the adhesion wound, the Shi Buhui that changes dressings causes secondary damage; Because the promoting healing mechanism of two kinds of materials is different, its promoting healing curative effect will play chemiluminescence.
Summary of the invention
This utility model provides a kind of biomembrane combine dressing with desirable medical dressing feature for the deficiency of existing traditional dressing.
This utility model is comprised of promoting healing biomembrane and self-adhering type Medical coating backing strap two parts.Wherein the promoting healing biomembrane is for by the film that makes after water-soluble chitosan and Oleum sesami blend, the drying, directly be covered on the wound surface during use, wound surface there is the moistening and antibacterial action of maintenance, has certain pliability and intensity, integral body forms gel after absorbing transudate, can not stick together with wound surface, change dressings convenient and do not produce secondary damage, the wound healing promoting curative effect is obvious.And self-adhering type Medical coating backing strap links to each other with the promoting healing biomembrane by medical adhesive, plays fixing, protection promoting healing biomembrane effect, can also absorb a large amount of transudates.
In order to realize above purpose, this utility model provides following technical scheme:
A kind of biomembrane combine dressing is characterized in that it is comprised of promoting healing biomembrane and self-adhering type Medical coating backing strap two parts.
Described biomembrane combine dressing, wherein the promoting healing biomembrane directly is covered in during use on the wound surface for by the film that makes after water-soluble chitosan and Oleum sesami blend, ionomer, the drying, belongs to treatment layer.
Described biomembrane combine dressing, wherein the promoting healing biofilm thickness is 0.1-0.5mm.
Described biomembrane combine dressing, wherein self-adhering type Medical coating backing strap plays fixing, protective effect to the promoting healing biomembrane, can also absorb a large amount of wound fluids.
Described biomembrane combine dressing, wherein self-adhering type Medical coating backing strap is comprised of water accepting layer and backing layer.
Described biomembrane combine dressing, wherein the water accepting layer of self-adhering type Medical coating backing strap is cotton adsorptive pads or non-woven fabrics adsorptive pads, and this water accepting layer links to each other with the promoting healing biomembrane by medical adhesive, and its length and width are all than the large 4-20mm in promoting healing biomembrane edge.The water accepting layer edge is greater than the promoting healing biomembrane, the transudate that spills from promoting healing biomembrane edge when being conducive to wound a large amount of transudate being arranged.
Described biomembrane combine dressing, wherein the backing layer of self-adhering type Medical coating backing strap is medical adhesive-bonded fabric, hospital gauze or medical films.
Described biomembrane combine dressing, wherein the mould release membrance of self-adhering type Medical coating backing strap is attached on the backing layer and water accepting layer with the body contact surface by binding agent.
Described biomembrane combine dressing wherein is coated with release paper on promoting healing biomembrane and the body contact surface.
The beneficial effects of the utility model: wound surface is had moistening, the antibacterial action of maintenance; Have certain pliability and intensity, absorb the whole gel that forms behind the transudate, can not stick together with wound surface, change dressings convenient and do not produce secondary damage, the promoting healing curative effect is obvious; Can absorb a large amount of transudates, can pollution clothes.
