Abstract
The invention relates to a natural high-polymer material adhesive bandage which comprises a sodium alginate film, wherein a polyester/adhesive/paper material is covered on the surface layer. The bottom layer composite film is prepared from sodium alginate, and thus, has the obvious effects of arresting bleeding, resisting infection, promoting wound healing and the like. The sodium alginate has favorable biocompatibility, and avoids the wound adhesion. The polyester/adhesive/paper material layer can completely obstruct liquid infiltration as a lining, and performs the function of protecting the wound. The composite film medical dressing is suitable for traumatic hemorrhage, various surgical incision sterile protective films, indwelling needle fixing films, sterile application and many other wound surface protective films.
Description
Technical field
The project category is biological, medical and medical mechanical domain science and technology field.
Background technology
With going deep into researching wound healing, people recognize run far deeper than using the purpose of dressing be for flap coverage, dressing should be able to also have hemostasis, analgesia, shield wound, it is anti-infective, avoid changing and cause when wrapping with straw secondary injury, and wound healing can be promoted.
Recent studies indicate that, moistening environment in wound healing faster.Under " wet wound healing " theoretical guidance, and with materialogy and the progress of industry, wound dressing also there occurs new change.Functional dressing made by with alginic acid as raw material is more than 10 types.The representational alginic acid fibre dressing characteristic such as have highly hygroscopic, easy removal, high oxygen flow and human compatibility good, is especially suitable for doing medical surgical material.
As use of the national policy to antibiotic is strictly controlled, the nursing of postoperative wound is the key measure for improving postoperative curative effect.This project implementation will greatly improve hospital's care following level, preferably serve patient, improve the rehabilitation effect of postoperative wound.The surface of a wound is nursed using new type functional dressing, maintain wound moist state, thoroughly improve the pain of changing medicine for patient, surface of a wound secondary damage is avoided, Wound healing rate is significantly improved, effectively shortens wound healing time, Patient Global's treatment cost can be reduced, the Social benefit and economic benefit of hospital is improved, harmonious doctor-patient relationship is set up, the generation of medical tangle is reduced.
Although some seaweed fiber medical dressings are occurred in that now, because manufacturing cost height is not easy to popularization and application.
The present invention is designed according to the film forming and biocompatibility of sodium alginate, using modern manufacture craft, can be made into various external application dressing easy to use, with hemostasis, analgesia, shield wound, anti-infective, and can promote wound healing.How auspicious this observation of Jing, its hemostasis average time be 1 point 31 seconds, and have significant easing pain and diminishing inflammation to act on, wound first intention rate 100%.
The content of the invention：
The purpose of the present invention is for traumatism and bleeding, prevention wound infection, promotes wound healing, there is provided a kind of medical dressing of composite film.
The technical scheme is that：Thing net (supplementary material) → weigh → dispensing → sodium alginate heating for dissolving → heating stirring that adds water adds glycerine, Tween 80 → stir → filter → vacuum outgas → dried coating film → cutting → section → test → packing → finished product.
Description of the drawings
Fig. 1 is a kind of process flow diagram of natural macromolecular material wound dressing of the invention.
Used as a kind of natural macromolecular material, sodium alginate has the filmogen of good biocompatibility：1. it is non-toxic, nonirritant.2. it is stable in properties not find incompatibility with compatibility of drugs.3. film forming demoulding performance preferably, can be formed with certain toughness and flexibility, and can bear the film of certain pulling force.4. rapidly expansion forms diaphragm to meet water energy, without different smell., abundant raw material, it is easy to get, and cheap, simple production process.
Beneficial effects of the present invention are：Because bottom composite membrane is made with Bletilla glucomannan with marine alga sodium, thus can have significant hemostasis, it is anti-infective, the effects such as promote wound healing.Bletilla glucomannan and sodium alginate have good biocompatibility, it is to avoid wound it is viscous glutinous.And polyester/viscose glue/paper material layer completely liquid barrier can permeate as backing, while play shield creation using.
Description of the drawings
Fig. 2 is a kind of structural representation of natural macromolecular material wound dressing of the invention.
1. the sodium alginate film (functional layer) on adsorptive pads surface is applied to
2. adsorptive pads (functional layer)
3. non-woven fabrics medical pressure-sensing adhesive plaster or ventilative TPU medical pressure-sensings glued membrane (except non-self-adhesive)
4. release liners (except non-self-adhesive)
Specific embodiment
The present invention is different according to the material of composition to be adapted to clinical practice, is divided into self-adhering-type (I types) and non-self-adhesive (II types)；Back sheet is I types A by the wound dressing that non-woven fabrics medical pressure-sensing adhesive plaster and water accepting layer (adsorptive pads, sodium alginate wound-protecting film), release liners are constituted；Back sheet is I types B by the wound dressing that ventilative TPU medical pressure-sensings glued membrane, water accepting layer (adsorptive pads, sodium alginate wound-protecting film), release liners are constituted；II types are made up of (such as Fig. 2) the sodium alginate film and adsorptive pads for being applied to adsorptive pads surface.
Claims (1)
1. one, functional membrane proportioning
Sodium alginate, glycerine, the proportioning of Tween 80 are strict controlled in 2%, 12%, 0.2%；
2nd, technological process：
Thing net (supplementary material) → weigh → dispensing → sodium alginate heating for dissolving → heating stirring that adds water adds glycerine, Tween 80 → stir → filter → vacuum outgas → dried coating film → cutting → section → test → packing → finished product.
The key points for operation of production technological process are：
1., according to the physicochemical property of sodium alginate, water temperature should be controlled at 60 DEG C during dissolving；
2. reduction of feed volume is strict controlled in every 500ml/ square metre during film；
3. heated-air drying, temperature control is at 80 DEG C.
