Detailed description of the invention
Below in conjunction with accompanying drawing, this utility model is further illustrated:
A kind of scar dressing, comprise multiple functional structure layer, described multiple functional structure layer sets gradually as contact layer 1 from inside to outside, dressing layer 2, watertight composition 3, described contact layer 1 is medical release paper, described dressing layer 2 is made up of layer of polyurethane 4 and filler particles 5, described layer of polyurethane 2 adopts polyurethane hydrogel colloid, described filler particles 5 is embedded in described layer of polyurethane 4 hole, described filler particles 5 comprises controlled release formulation of capsule, described controlled release formulation of capsule is made up of capsule core and capsule skin, described capsule skin adopts high molecular polymer to make, it has stronger damp proof, acidproof, alkalescence can, described capsule core is by effective agent and solvent composition, described effective agent is made up of dispersant and plant extract, described capsule core is wrapped in described capsule Intradermal, form less cryptomere preparation, the non-woven fabrics that described watertight composition 3 is sterilized for ethane via epoxyethane, described watertight composition 3 surface is provided with the uniform groove 6 of spacing, described watertight composition 3 surface is provided with stick 7.
The porosity of described polyurethane hydrogel colloid controls 50% ~ 60%.
It is several microns of microgranules to hundreds of micron that described plant extract is dispersed into particle diameter by described dispersant by physical method.
The particle diameter of described controlled release formulation of capsule is between 400 microns to 500 microns.
Described diameter of particle is less than described controlled release formulation of capsule particle diameter.
Described controlled release formulation of capsule can according to the different time, the plant extract amount of release variable concentrations, and its release profiles is bending curve.
Described controlled release formulation of capsule is made by interfacial polymerization, Coacervation.
Described plant extract is Asiaticoside and human body cell somatomedin.
Described stick 7 extends along described watertight composition 3 axial direction.
Described stick 7 length is greater than described watertight composition 3 length.
During utility model works, medical release paper on contact layer 1 is by dressing layer 2 and patient wound's isolation, avoid dressing impaired, the wound surface impaired initial stage, there is a large amount of transudates on patient wound surface, because polyurethane itself has more hydrophilic group, possesses three-dimensional net structure, rapid expansion after water suction, form semipermeable hydrogel colloid, hydrogel colloid can reach very large relative molecular mass, therefore it still has enough adsorbances after absorption wound fluid, the effect holding moisturizing can be played to the transudate of absorption, thus produce mechanical pressure power and excellent adhesive force, and then the cicatrix to hypertrophy, silt trace plays excellent inhibitory action.The porosity of polyurethane determines its effect that is penetrating, the moisture that absorbs water, releases for slow time, too small, and the requirement that cannot reach penetrating, absorb water is excessive, make its insufficient strength, therefore its porosity controls 50% ~ 60%.
Controlled release formulation of capsule in the filler particles 5 of filling in the space of polyurethane hydrogel is with the plant extract of release of different time varying number, to meet medication amount required in human body healing process, having simplified original technology mid-early stage discharges medicine in a large number, need the process that the later stage is constantly added, make human body obtain the recovery continued.
Filler particles by high molecular polymer as capsule skin, there is stronger moisture-proof characteristic, prevent the dissolving of medicine, and due to plant extract be Asiaticoside and human body cell somatomedin, therefore it promotes the healing of wound surface, stops the generation of cicatrix, and adopt high molecular polymer to be capsule skin, dissolve the problem of plant extract after avoiding polyurethane hydrogel water suction, the function of plant extract is maximized.And when covering, only need according to the size of wound surface, after the groove 6 on watertight composition 3 surface fractures, utilize the stick 7 on watertight composition 3 surface to adhere to, not only avoid problem that cutting produces fines and also solve the problem that dressing easily drops, need use adhesive plaster.This utility model practical value is high, can be widely used in medical supplies manufacturing technology field.
In sum, be only preferred embodiment of the present utility model, not be used for limit this utility model implement scope, all equalizations of doing according to shape, structure, feature and the spirit described in this utility model right change and modify, and all should be included in right of the present utility model.
