The wound-protecting product is clinically matched with a special negative pressure pump for use, has the advantages of fast wound surface healing, low infection rate, less times of exchanging dressing, little use of antibacterial drug, reduced medical cost and the like compared with the conventional open-type drug exchanging, and is mainly used for body surface wounds, burns, granulation tissues and the like clinically.
Description
Technical field
The present invention relates to the medical care products field, particularly the wound care products field.
Background technology
In traditional surgery, at burn, scald, serious soft tissue injury due to a variety of causes, shortage, major operation and contamination of incision, disunion otch, and the post processing of the various chronic difficult difficult more property wounds such as wound surface that heal, not only need to use a large amount of antibiotic antiinflammatory, and because the influence of blood stains, transudate, medical personnel need frequent more change dressings especially, the result of Chu Liing like this, not only increased the wounded's pain, the infection rate of inflammation, and wound healing is slow, medical personnel's workload is big.
At present, the dressing that medical personnel use mainly is textile goods, as medical absorbent cotton and medical absorbent cotton/gauze, not only consumes a large amount of high quality cottons, and will be through ungrease treatment, and its disadvantage is and the wound surface adhesion, brings the secondary wound to the wounded, has increased misery.
Summary of the invention
Technical problem to be solved by this invention is: a kind of disposable use negative pressure drainage Wound-protecting product that can cooperate special negative pressure pump to use is provided, so that continue or interruption absorption juice and removal edematous fluid, alleviate edema, fully drain, reduce the change of dressing number of times, bring the environment that promotes healing for patient's wound surface.
The present invention solves its technical problem and adopts following technical scheme:
Disposable use negative pressure drainage Wound-protecting product provided by the invention, this Wound-protecting product mainly is made up of sponge block and drainage tube, wherein: described sponge block adopts carboxymethyl chitosan/polyvinyl alcohol compound sponge, described drainage tube has one at least, the body of every drainage tube is provided with a plurality of conduction holes, and the conduction hole part of this drainage tube is inserted in the sponge block along the sponge block horizontal direction.
Described carboxymethyl chitosan/polyvinyl alcohol compound sponge, its preparation process comprises the polyvinyl alcohol heat of solution, acetalation and foaming and compound with carboxymethyl chitosan, specifically: with the degree of polymerization is that the high viscosity polyvinyl alcohol of 2000～2600 complete alcoholysis or not exclusively alcoholysis is a raw material, with carboxymethyl chitosan and polyvinyl alcohol dissolving, add acid again, formaldehyde and foaming agent blend, the shared percentage by weight of each raw material is carboxymethyl chitosan 8-17%, polyvinyl alcohol 23-26%, acid 28-33%, formaldehyde 23-26%, foaming agent 7-8%, hot briquetting in baking oven gets carboxymethyl chitosan/polyvinyl alcohol compound sponge.
Carboxymethyl chitosan/polyvinyl alcohol compound sponge that the present invention adopts is applied for patent of invention by the inventor, and this composite sponge has good springiness, pliability is big, intensity is high, and abrasive resistance is strong, the advantage of long service life.And this kind composite sponge water absorption height, good biocompatibility has the wound healing of promotion and anastalsis characteristics, can be widely used as wound dressing, artificial skin substitute etc.Experiment shows that the tensile strength of the composite sponge of addressing among the present invention can reach more than the 2MPa, and elongation at break can reach more than 350%, for the crucial index of wound healing---water absorbent rate then can reach more than 50%.
Above-mentioned disposable use negative pressure drainage Wound-protecting product provided by the invention, the blood stains of its patient's wound behind the drain surgical operation and the application of transudate.
Above-mentioned disposable use negative pressure drainage Wound-protecting product provided by the invention, uses such as main donor table wound, burn, granulation tissue.Its using method is: clean wound surface in the clinical operation, after removing slough and foreign body, adopt and the be complementary Wound-protecting product of specification of wound surface size, make it to contact fully with wound surface, drainage tube is directly drawn by edge of wound, seals whole wound surface with the PU laminated film, with drainage tube by connecting straight-through or threeway is connected in special negative pressure pump, adjust negative pressure value to 16kpa, begin to continue or be interrupted juice and the removal edematous fluid of drawing wound surface.
Disposable use negative pressure drainage Wound-protecting product provided by the invention compared with prior art has following main beneficial effect:
One. overcome the shortcoming of conventional medical dressing in the past, utilize the transparent sealing pad pasting to make the open wound sealing, use special negative pressure pump to produce certain negative pressure, continue or be interrupted the wound surface that acts on after the debridement by drainage tube and dressing, constantly draw juice and remove edematous fluid, can alleviate edema, fully drain, alleviate infection, and can avoid bringing the misery of secondary wound to the patient with the wound surface adhesion.
They are two years old. and can increase endovascular blood flow in the wound surface fast, promote the growth of new vessels, promote the formation and the growth of granulation tissue, the supply of lasting fresh blood is provided, bring the oxygen that promotes healing and nutrition, somatomedin to wound surface.
They are three years old. conventional open changing dressings, and it is fast to have a wound healing, and infection rate is low, and more the change dressings number of times is few, and antibacterials are used few, reduce advantages such as medical fee.A large amount of clinical trials prove, can make the healing time of acute injury accelerate 61%, and the more traditional Therapeutic Method of the healing time of chronic wound is accelerated 2-3 doubly, reduces medical fee 38%.
They are four years old. and based on above-mentioned effect, so market prospect is wide, has the potentiality of applying.
In a word, the present invention has that wound healing is fast, and infection rate is low, and the chronic wound tissue is activated again, growth healing fast, and more the change dressings number of times is few, and antibacterials are used few, reduce medical fee, and are beneficial to and advantage such as apply.
