Description

Novel moist dressing

Technical field

This utility model relates to medical instruments field, specifically a kind of novel moist dressing.

Background technology

Correct wound care theory points out, best nursing should be: optimum wound healing environment is provided; Remove slough; Prevent the bacterial invasion wound; Do not stimulate wound and surrounding skin; Keep 37 ℃ of wound temperature; Select suitable dressing, keep wound moistening, help the granulation tissue growth.

And there is following drawback in traditional dryness healing environment: the local dehydration of wound surface, form incrustation, and hinder epithelial cell and creep; Bioactive substance is lost, and healing rate is slow; Dressing and the adhesion of wound new granulation tissue, more change dressings time damage wound surface; Frequently change dressings more, descend the wound surface local temperature, and the cell division growth rate slows down; Wound surface can not intercept bacterial invasion with extraneous without the barrier barrier, and the chance of cross infection is many; Incrustation causes wound pain.

Along with the proposition of wet union theory, the advantage of wet union also embodies gradually: can not form dry crusts, mechanical injuries wound surface while reducing change of dressing; Keep the active substance in transudate and promote its release; While changing dressings, pain obviously alleviates, and feels comfortable, convenient; Easy and simple to handle, reduce dressing change frequency; Extend and change dressings interval time, reduce nursing cost; Reduce the chance of wound infection; Increase patient's comfort.

The mechanism of wet union: 1) regulate the wound surface oxygen tension, promote the formation of blood capillary: because moist environment is usually to form below closure dressing, the normal formation of the microenvironment of wound part hangs down oxygen tension; 2) be conducive to slough and fibrinous dissolving: during wet union, contain the histone lyase in the wound surface exudate, can promote dissolving and the absorption of these tissues; 3) promote the release of multiple somatomedin: contain multiple somatomedin in wound fluid, above-mentioned somatomedin plays very important effect in the agglutination of wound surface; 4) be conducive to cell proliferation and differentiation and divide a word with a hyphen at the end of a line: can keep the activity of cell and enzyme under moistening environment, these will help the healing of wound; Simultaneously, cell can be divided a word with a hyphen at the end of a line more fast under moist environment; 5) reduce the chance that infects: the moist dressing wound infection rate is 2.6%; Under the tradition wound surface is processed, (dryness) infection rate is 7.1%; 6) keep wound surface constant temperature: be beneficial to cell mitogen; 7) keep wound surface moistening: to form without incrustation, avoid the mechanical injuries again of new granulation tissue; The teleneuron of protection wound surface.

currently used moist dressing is all generally by moist inner core, middle non-drying glue layer and the design of waterproof outer layer integral type, but there is following defect in traditional moist dressing: 1, paste the bad control in position: due to moist inner core less than non-drying glue layer, in pasting process along with a side pressure sensitive adhesive on skin, cannot see the position of moist inner core, moreover because non-drying glue layer and waterproof outer layer generally have certain dilatability, very likely moist dressing can be pasted askew, moist dressing need to be taken off again and pastes, if pull affected part can increase patient's the pain of injury, on the other hand, repeated adhering can affect the viscosity of adhesive sticker, moist dressing has the possibility that comes off, 2, the effect of moist inner core is difficult to guarantee: the certain humidity of moist inner core needs, integral type arrange can affect the humidity of moist inner core, and then affects the effect of moist dressing, on the other hand, if when moist dressing added medicine, if the integral type setting, As time goes on, medicine can volatilize and lose efficacy, and affects the curative effect of moist dressing, 3, breathability is not good: because the moist dressing outside is provided with non-drying glue layer and watertight composition, its air permeable effect is bad, the temperature and humidity that can find affected part when taking off moist dressing is relatively large, and the skin around affected part presents white shape, has affected the time of wound healing.

The utility model content

According to above-mentioned weak point, the purpose of this utility model is to provide the moist dressing that a kind of moist inner core separates with outer non-drying glue layer, watertight composition, moist inner core is packed separately, not only guaranteed the curative effect of moist inner core, and be not provided with adhesive sticker on the watertight composition of moist inner core position, increased the breathability of moist dressing.

For achieving the above object, the technical solution of the utility model is: a kind of novel moist dressing, it comprises dressing inner core and base material, dressing inner core periphery is provided with independent packaging, and wherein the dressing inner core comprises internal layer adsorptive pads and the outer bearing hydrocolloid dressing layer that is comprised of hydrocolloid, cohesive material and syntheitic elastomers; Base material comprises the non-drying glue layer of base material inner surface and the watertight composition of base material outer surface, is not provided with non-drying glue layer with the dressing inner core position that is complementary in the middle of base material.

Preferably: the bearing hydrocolloid dressing layer surface of described dressing inner core also is provided with release paper.

Preferably: on one side the release paper on described bearing hydrocolloid dressing layer surface is provided with the hands torn edges.

Preferably: the independent packaging of described dressing inner core periphery is provided with easy torn edges angle.

Preferably: described base material non-drying glue layer surface is provided with release paper.

Preferably: the release paper on described base material non-drying glue layer surface is two half mould settings.

Preferably: the watertight composition of described base material outer surface is provided with a plurality of air-vents.

Preferably: described moist dressing is strip, circle, ellipse or square.

The beneficial effects of the utility model are: 1,, by with the independent packaging of dressing inner core, can guarantee the humidity of moist dressing, can guarantee again the property of medicine of moist dressing, more can bring into play its curative effect; 2, dressing inner core independent packaging, first spread on affected part with the dressing inner core during use, more outer base material is sticked on skin, more can accurately grasp the position, affected part, once just moist dressing can be pasted; 3, be not provided with non-drying glue layer with the dressing inner core position that is complementary in the middle of base material, make moist dressing more ventilative, be conducive to the healing in affected part; 4, according to difform affected part, difform moist dressing is set, has more specific aim.
