Abstract

The utility model provides skin wound dressing. When the bleeding volume of a wound is large, the skin wound dressing can adsorb and evaporate liquid such as blood and water. The skin wound dressing can retard volatilization of the liquid such as the blood and the water when the bleeding volume of the wound is reduced in a later period. The skin wound dressing comprises a polyurethane foam layer, wherein the polyurethane foam layer expands after adsorbing the liquid. The polyurethane foam layer comprises a front face which is in contact with the skin and a back face which is far away from the skin, wherein protruding blocks are arranged on the front face of the polyurethane foam layer in an adhered mode, each protruding block cannot expand or deform after being in contact with the liquid, and the protruding blocks are arranged on the front face of the polyurethane foam layer at intervals. Through holes are formed in polyurethane foam layer at intervals. Furthermore, the cross section of each protruding block is rectangular, and the top end of each protruding block is chamfered. Preferably, each through hole is cylindrical.

Description

A kind of skin wound dressing

Technical field

This utility model relates to the wound dressing curable product, is specifically related to be applied to the wound dressing that vein isolates etc. hemorrhage state.

Background technology

Be similar to minor operation and vein and the bigger wound of amount of bleeding such as isolate, generally all can use wound dressing to wrap up, its amount of bleeding of different wounds is also different, and the amount of bleeding when same wound is in different conditions also is different; There will be two kinds of situations in practice: the one, and amount of bleeding is excessive, the adhesive failure at wound dressing and contact skin place, wound dressing is in the drift of skin and wound surface even come off; The 2nd, wound sharply reduces in the amount of bleeding in later stage, and wound is too dry, and wound dressing can't keep near the humidity the wound, easy and wound adhesion.

The utility model content

At above-mentioned problems of the prior art, this utility model provides a kind of can adsorb and evaporate liquid such as blood and water when the wound bleeding amount is big, and the volatilization that can block liquid such as blood and water when wound later stage amount of bleeding reduces.

The technical scheme that its technical problem that solves this utility model adopts is: a kind of skin wound dressing, comprise the polyurethane foam that expands behind the adsorptive liquid, and froth bed comprises with the positive of contact skin with away from the back side of skin;

Positive bonding being manufactured with of froth bed contact no dilatancy projection afterwards, the discontinuous froth bed front that is arranged in of a plurality of projections with liquid;

The discontinuous through hole of offering on the froth bed.

Further be: above-mentioned projection cross section is rectangle; The projection break corner.

Preferably: above-mentioned through hole is cylindrical hole.

The beneficial effects of the utility model are:

The dressing of this utility model skin wound, when the skin wound dressing paste is overlying on the skin wound place, projection is close to skin layer, after liquid such as the water of wound or blood are adsorbed by froth bed, froth bed expands, increase the aperture of through hole when increasing adsorption area, can in time water or blood absorption be dissipated, be difficult for causing the phenomenon of dressing drift; Meanwhile, when amount of bleeding or water minimizing, froth bed shrinks, and reduces adsorption area, and through-hole aperture reduces, the volatilization of retardance liquid, the humidity of maintenance wound adnexa.So, when whole wound dressing can guarantee that amount of bleeding is big, adsorptive liquid as much as possible was preserved moisture when amount of bleeding reduces as far as possible.

Description of reference numerals:

The 1-froth bed, 2-through hole, 3-projection.

The specific embodiment

Below in conjunction with drawings and Examples this utility model specific embodiment is described:

Fig. 1 shows the specific embodiment of the present utility model, and as shown in Figure 1, the dressing of this utility model skin wound comprises the polyurethane foam 1 that expands behind the adsorptive liquid, and froth bed 1 comprises with the positive of contact skin with away from the back side of skin; This polyurethane foam 1 has certain elasticity, and with liquid such as water or blood after adsorption swelling, after-contraction is to original state after liquid evaporation.

Positive bonding being manufactured with of froth bed contact no dilatancy projection 3 afterwards, a plurality of projections 3 discontinuous froth bed fronts that are arranged in liquid;

The discontinuous through hole 2 of offering on the froth bed 1.

When above-mentioned skin wound dressing paste is overlying on the skin wound place, projection 3 is close to skin layer, after liquid such as the water of wound or blood are adsorbed by froth bed, froth bed 1 expands, increase the aperture of through hole 2 when increasing adsorption area, can in time water or blood absorption be dissipated, be difficult for causing the phenomenon of dressing drift; Meanwhile, when amount of bleeding or water minimizing, froth bed shrinks, and reduces adsorption area, and through hole 2 apertures reduce, the volatilization of retardance liquid, the humidity of maintenance wound adnexa.

Generally speaking: above-mentioned projection 3 cross sections are rectangle; Projection 3 break corners.So can increase and paste area, make paste more stable.

Preferably: above-mentioned through hole 2 is cylindrical hole.The contraction of cylindrical hole and expansion can be fit to evaporation more and keep the structure of moisture.

By reference to the accompanying drawings this utility model preferred implementation has been done detailed description above; but this utility model is not limited to above-mentioned embodiment, and all are that the improvement in the ken that those of ordinary skills were possessed that carry out on the basis all drops in the protection domain of the present utility model with thought of the present utility model.

Do not break away from design of the present utility model and scope and can make many other changes and remodeling.Should be appreciated that this utility model is not limited to specific embodiment, scope of the present utility model is defined by the following claims.
