Abstract
Novel pressure bandages are described comprising either a substantially triangular prism-shaped section of compressible, resilient material which has been adhered to a carrier tape or a substantially rectangular prism-shaped section of compressible, resilient material which has been adhered to a carrier tape in a manner which causes the section to assume a substantially triangular prism shape. Novel methods for making the same are also described. The pressure bandages, since they provide localized pressure to the surface of skin, are particularly suitable for impeding the bleeding from minor wounds.
Claims14
A pressure bandage comprising:
- (a) a carrier tape comprising a backing and a layer of pressure-sensitive adhesive on one surface of said backing;
- and
- (b) a substantially rectangular prism-shaped section of compressible, resilient material having two adjacent faces attached to said carrier tape by said pressure-sensitive adhesive such that said section of said material assumes a substantially triangular prism shape.
A strip of a carrier tape having situated thereon a plurality of sections of compressible, resilient material, said carrier tape comprising a backing and a layer of pressure-sensitive adhesive on one surface of said backing, and said sections of said material being substantially rectangular prism-shaped and having two adjacent faces attached to said carrier tape by said pressure-sensitive adhesive such that said sections of said material assume a substantially triangular prism shape.
A process for making a continuous strip of pressure bandages, said process comprising the steps of
- (a) providing substantially rectangular prism-shaped sections of compressible, resilient material and a carrier tape comprising a backing and a layer of pressure-sensitive adhesive on one surface of said backing;
- (b) at predetermined locations, attaching a first face of said sections of said material to said carrier tape by said adhesive layer;
- and
- (c) deforming said sections of said material such that a second face of said sections of said material adjacent said first face contacts and becomes attached to said carrier tape by said adhesive layer.
