Summary of the invention

The purpose of this utility model provides a kind of postoperative wound and applies ointment or plaster, adopt this applying ointment or plaster on the operative incision, have good moisture preserving, wound healing is fast, analgesic effect lastingly, safely, have no side effect, subside a swelling fast, can prevent not long cicatrix after adhesion of postoperative mucosa and the healing.

The technical solution of the utility model is: design a kind of postoperative wound and apply ointment or plaster, it is characterized in that: be connected with spun laced fabric in adhesive sticker basic unit, be surrounded by the suction cotton core in the spun laced fabric, post the permanent magnetism sheet on the suction cotton core, the outer surface of applying ointment or plaster has protection sheet.

Described spun laced fabric upper surface has antiseized moisture film.

On the described spun laced fabric trace element is arranged.

Described permanent magnetism sheet outer surface has copper, ferrum, the zinc microelement coating that promotes wound healing, and wherein copper accounts for 0.5%-1%; Ferrum element accounts for 93%-95%; Zinc element accounts for 4%-6%.

Described trace element is a copper.

Described trace element is a ferrum element.

Described trace element is a zinc element.

In the described dressing moisture film is arranged.

Spun laced fabric both sides in the described adhesive sticker basic unit are connected with protection sheet respectively.

Trace element in the described dressing is that the fineness crossed through nanotechnology treatments is at 120 orders-200 purpose trace element.

This utility model characteristics are: wound healing is the biological process of a complexity.The different mechanical factors acts on operation and the wound surface that different tissues causes and varies in size, and wound healing process is difference to some extent.Operative incision behind thorough debridement and suturing, Level of organization involutory good, wound healing is smooth, scar tissue seldom person is primary healing.Tissue defect is bigger, and slough is more or with infection, needing granulation tissue to fill up wound surface can healing person be secondary healing.The agglutination of operative incision roughly is divided into three phases, and they both had any different, and interknits juxtaposition again.Phase I is inflammatory reaction phase (being stage of preparation), exudate solidifies in wound, fibrin and fibronectin are bonding with wound, platelet, neutrophilic granulocyte, mononuclear cell, fibroblast and blood capillary enter in the wound in succession, justacrine plurality of enzymes and somatomedin start agglutination.Generally in 48 hours, the existing epithelium in the surface of whole wound covers.This phase lays a good foundation for healing, but wound tissue tension intensity is very low in initial 2-3 days.Phase III is a proliferative phase, and postoperative 4-5 days granulation tissue (fibroblast, blood capillary system and substrate) active proliferation collagen stroma occurs, and increases sharply in the wound, and tissue tension intensity raises rapidly, and the peak of general hyperplasia is 2 weeks approximately after surgery.Phase III is the period of maturation, postoperative about January hyperplasia and tissue tension growth rate slow down, cell number and vascularization reduce.After 60-80 days in the wound total collagen quantity reach normal value, and the synthetic of collagen still proceeded with decomposing, the cicatrix refigure, scanning electron microscope confirms that cicatrix fiber figure is in slow change in the several months.In wound healing process, microcirculatory perfusion well is a prerequisite with organizing oxygen supply, and macrophage, platelet and fibroblast play a crucial role.And the magnetic field that the permanent magnetism sheet produces has blood circulation promoting, the absorption that can quicken exudate is dissipated, removed the stimulation of inflammation swelling to nerve, observed by the microcirculation of many cases being sprained patient, the treatment metarteriole vein stasis of blood stagnates, slow blood flow, the part serious symptom has capillary break-up to go out clot, all case blood flow quickenings after the magnetic therapy, and the vein end stasis of blood stagnates and dissolves gradually, wherein most patients cure the back check and all recover normal, and the microcirculatory effect that has clear improvement is described.

Trace element effect in the dressing is as follows:

1, the synthetic and Cu of collagen ²⁺Relation: the tropocollagen molecules that three peptide chains are formed, its tensile strength of initial period be a little less than.As time passes, between three peptide chains or neighboring molecule form covalent bond, tensile strength just is increased.Though between the intramolecularly of collagen fiber and the molecule character of covalent bond also under study for action, some key internal reaction is determined, as the interconnection of lysine between two peptide bonds.Lysine changes aldehyde earlier into, and the aldehyde radical on two peptide chains reacts and links up then.Under the catalysis of lysyl amino oxidase lysine become-need Cu in the reaction of semialdehyde-a amine adipic acid ²⁺Be cofactor.The exhaustion of copper or the not enough formation and the crosslinked connection that will influence aldehyde.

2, the synthetic and Fe of collagen ²⁺Relation with ascorbic acid: also have characteristics during collagen is synthetic, be that proline or lysine are not that first hydroxyl turns to resynthesis collagen after hydroxyproline or the hydroxylysine, but proline or lysine participates in after the synthetic procollagen, makes proline hydroxylating on the peptide chain by the peptidyl-prolyl hydroxylase again.In the hydroxylating process, the oxygen atom in the hydroxyl is from airborne molecular oxygen.The peptidyl-prolyl hydroxylase is substrate and Fe except that needing a-copper 1,3-propanedicarboxylic acid ²⁺Outside cofactor, also need ascorbic acid as electron donor.So ferrum and ascorbic acid are the necessary materials of wound healing.The general otch that does not infect, postoperative 7d left and right sides collagen forms, and can make patient be engaged in general unlikely the splitting of movable otch, and can take out stitches and leave hospital this moment.But the formation of wound collagen and crosslinked sustainable several months or for many years, this period still needs constantly to replenish ascorbic acid.If lack ascorbic acid, vitamin C deficiency can appear in patient, and otch still has the possibility of splitting under external force.

3, the relation of wound healing and zinc: zinc is the coenzyme of many enzymes in the body or the composition of prothetic group, and extensive influence body internal protein, fat and sugar metabolism.Particularly zinc is the coenzyme composition of archaeal dna polymerase and RNA polymerase, with the division and the proteinic synthetic substantial connection that all has of cell.With closely-related proteoglycan of wound healing and collagen fiber, on chemical constituent, all belong to protide, so zinc also influences the synthetic of them.Moreover, zinc is more remarkable to the influence that the wound epithelium covers, and this influences cell division and growth from zinc, influences proteinic synthetic, and 20% zinc is present in the skin in the body, especially concentrates on epithelial tissue (zinc content is up to 120～250 μ g/g) and can obtain explaining.Many scholar's research affirm that body is in when hanging down the zinc state, and zinc supplement has facilitation to wound healing.And stress the time (as operation) discharge and increase along with urinary nitrogen, urine phosphorus, urine sulfur etc., urine zinc is discharged and is also increased.Because of zincode easily combines with some low-molecular-weight chemical compounds such as aminoacid, beta-hydroxybutyric acid etc. in the blood plasma, filtered and discharge by kidney, so when albumen was lost from urinate, zinc was also lost thereupon.Urine zinc is lost the degree that descends with blood plasma zinc and the length of persistent period with the character of wound and the order of severity and different.So operation back body more or less is in low zinc state for some time, as is replenished then and can be promoted the epithelium wound healing.If zinc supplement before the operation although postoperative still has blood zinc to reduce, can keep normal level.Come zinc supplement with zinc sulfate or zinc acetate clinically.Food aspect, animal skin zinc content are all very high, when as a supplement during the source of glycine, proline, also having obtained the zinc of volume with Corii Sus domestica or Ungula Sus domestica simultaneously.

The utlity model has following effect in a word:

1, has good moisture preserving, be beneficial to wound healing.

2, good permeability can guarantee the eupnea of skin.

3, the exudation effect is strong, is beneficial to tissue repair.

4, analgesic effect lastingly, safely, have no side effect.

5, detumescence is fast, than common dressing fast about 3 days.

6, antiinflammatory can be avoided infection of incisional wound, be alleviated patient's burden.

7, can prevent the adhesion of postoperative mucosa.

8, can shorten healing time.

9, finished the cicatrix time of moulding again in advance in 5 months, and not long cicatrix after the healing.

10,1/3 time finished in advance can to make healing time.

11, subcutaneous nothing scleroma phenomenon, the tissue blood circulation is good.

12, sticking wound is removed when changing dressings the back destruction to new granulation tissue from.

13, can make the ulcer wound healing, alleviate patient's misery.

14, the wound after the healing, the sensation of depletion of YIN it rains sufferings has been removed patient's sequela from.

15, contained trace element is copper, ferrum, zinc in the dressing, and these trace element have facilitation to wound healing, is that wound healing is requisite.

16, the moisture film in the dressing keeps the wound surface moist environment, and the damaged tissues wound surface is created a moist environment, because the autolysis of moistening wound surface, its healing can be simplified debridement, promotes the cleaning of wound.Because the wound surface exudate is a ring of whole agglutination, exudate contains a great deal of to the indispensable somatomedin of wound healing process, and its kind and quantity play important regulating action to wound healing; Its function comprises stimulates fibroblast proliferation as macrophage, all many-sides such as chemical chemoattractant of neutrophilic granulocyte and smooth muscle cell.Moist environment helps the wound healing performance: (1) protection granulation granule; (2) the inflammation diffusion is disappeared; (3) wound pain alleviates; (4) exudate reduces; (5) fibrin film appears; (6) growth of wound surface microbial bacterial is suppressed, and pathogen disappears; (7) wound re-epithelialization ability improves.

One, accelerates healing speed, minimizing cicatrization.

Wound healing time, Dditch discovers: wound surface 10d healing person, the incidence rate of cicatrix is 0-6%, hinders back 10-14d healing, and incidence rate is 4%-19%, and after the 14-21d healing, sending out the back rate is 30%-35%, and mostly is hypertrophic cicatrix after hindering.Wound 21d is just healing later on, and incidence rate is 60%-80%.This shows healing time to the generation of growth property cicatrix be formed with confidential relation.Of the present utility model applying ointment or plaster compared fast 18-20d to speed of wound healing than the wound of common dressing parcel, compare with biopsy wound healing rate, all healings of two week of wound back of applying ointment or plaster and covering of the present utility model, and healing back cicatrix is slight, and common dressing covers wound, have only 63% healing, and the generation of hypertrophic cicatrix is arranged more.

Two, pain relieving, detumescence, antiinflammatory

The postoperative disorganization, circulatory disturbance, neural destruction exposes, and organizes transudate that the stimulation of otch is caused pain.Of the present utility model apply ointment or plaster cover pain behind the wound and significantly be lighter than the patient that those fine mesh spun laced fabrics cover wounds, particularly postoperative anesthetic action and disappear after, in 72 hours the pain difference very obviously, (p (0.001).Of the present utility model applying ointment or plaster can be loosened 50-100 μ arteriole and be improved the vasomotion of 20-30 μ arteriole, and the permeability that suppresses venule portion is hyperfunction, makes the blood exudate of the state of smouldering recover normal rapidly.Under effect of applying ointment or plaster of the present utility model, blood can bring out a kind of Joule heat in body circulation time, impels telangiectasis, and blood flow is accelerated, so reach analgesic effect.And then suppress histamine, 5-hydroxy tryptamine, the slow stimulation that swashs chemical substances such as titanium to teleneuron.Eliminating postoperative edema is postoperative human body spontaneous recovery process, of the present utility model apply ointment or plaster to have to stop ooze out and sorbefacient dual function, the hematoma area is littler by about 50% than common dressing after 3 days, regression time fast 60%; This is that blood flow rate has due to the optimum effect because of of the present utility model applying ointment or plaster to microvascular permeability, colloid osmotic pressure.Of the present utility modelly apply ointment or plaster better, bacterium property inflammation is had better curative effect too the aseptic inflammation curative effect.Because of leukocyte under the action of a magnetic field, phagocytic function obviously strengthens, neutrophilic granulocyte accounts for 70% of total white blood cells, neutrophilic granulocyte has to be engulfed and germ-resistant function, in body, play important defense reaction, the inflammation of wound healing is a feature with the quick gathering of neutrophilic granulocyte to the injury promptly in early days, and it mainly act as infection.
