Abstract

A bandage construction that includes a sterile pad of a hygroscopic material is sufficiently porous to admit air therethrough, the pad being covered on the surface facing the wound with a layer of a soft non-woven fabric. A strip-like element is adhered over the outwardly directed surface of the pad and has portions thereof extending beyond each end of the pad, and a width that is substantially identical to that of the pad. The pad is constructed of a cellular plastic foam which is hygroscopic, non-allergenic and non-toxic, while at the same time it is sufficiently porous to pass air therethrough such that the facing surface of the wound is kept dry and provided with a continuous supply of air.

Claims

1. A bandage construction comprising:

a pliable strip;

a quantity of adhesive substantially covering one surface of said strip; and

a hydrophilic pad of a porous air permeable cellular material, the body portion surrounding the cells constituting a means for tenaciously holding body fluids, said pad adhering to said strip for being located in use over the wound and immediately adjacent areas.

2. A bandage construction as in claim 1 in which said strip has portions extending beyond the pad and which portions each include at least one tear line of perforations.

3. A bandage construction as in claim 1 in which said pad is constructed of a hydrophilic polyurethane foam.

4. A bandage construction as in claim 1 in which said pad and strip are assembled such that they have common edges coextensive with each other.

5. A bandage construction as in claim 1 in which the pad is constructed of a foamed hydrophilic polyurethane having a thickness sufficient to maintain permeability to air when compressed onto a wound.

6. A bandage construction comprising:

an elongated rectangular foraminous strip of a flexible plastic;

a pad of a hydrophilic air permeable foamed cellular plastic material, the body portion surrounding the cells defining a means for holding body fluids and having a width dimension substantially identical to that of the strip and adhered to said strip separating first and second portions of said strip extending beyond the pad; and

a cover of nonwoven material received over the pad exposed surface.

7. A bandage constructionn as in claim 6, in which said cover includes a relatively thin foraminous plastic sheet constructed of a material which does not adhere to the skin or wound.

8. A bandage construction comprising:

an elongated pliable strip; and

a quantity of adhesive substantially covering one surface of said strip;

a pad of porous air Permeable hydrophilic cellular material having a body portion surrounding the cells constituting a means for holding body fluids when adhering to said strip for being located in use over the wound and immediately adjacent areas, said pad being constructed of a polyurethane foam having cellulosic material incorporated therein.
