Abstract
A novel pressure bandage and transdermal patch is disclosed. The bandage comprises a (i) sanitary gauze layer to be applied against a wound; (ii) a compressed cellulose middle layer overlying said sanitary gauze layer; and (iii) an outside layer overlying said sanitary gauze and compressed cellulose layers and having adhesive wings which apply the bandage to the skin, whereby blood from the wound when leaking through the gauze layer will saturate the compressed cellulose material and thereby expand said cellulose layer against said sanitary gauge and outer layers, thereby applying active pressure to the wound while soaking up excess blood.
