Abstract
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.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
60 words
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.
Claim 2
Dependent Claim
60 words
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.
Claim 3
Dependent Claim
14 words
A pressure bandage in accordance with claim 1, wherein said material is resilient foam.
Claim 4
Dependent Claim
75 words
A pressure bandage in accordance with claim 1, wherein said carrier tape is substantially rectangular in shape and has a length which is greater than its width in dimension, and wherein said section of said material is attached to said carrier tape such that the line defining the apex of said section of said material when said section of said material is substantially triangular prism-shaped is substantially transverse to the length of said carrier tape.
Claim 5
Dependent Claim
14 words
A pressure bandage in accordance with claim 3, wherein said material is resilient foam.
Claim 6
Dependent Claim
72 words
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.
Claim 7
Dependent Claim
72 words
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.
Claim 8
Dependent Claim
11 words
The article of claim 5, wherein said material is resilient foam.
Claim 9
Dependent Claim
37 words
The article of claim 5, wherein the line defining the apex of each of said sections of said material when said sections of material are substantially triangular prism-shaped is substantially transverse to the length of said strip.
Claim 10
Dependent Claim
11 words
The article of claim 7, wherein said material is resilient foam.
Claim 11
Dependent Claim
9 words
A wound roll comprising the strip of claim 2.
Claim 12
Dependent Claim
9 words
A wound roll comprising the article of claim 8.
Claim 13
Dependent Claim
102 words
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.
Claim 14
Dependent Claim
102 words
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.
Claim 15
Dependent Claim
27 words
A process in accordance with claim 3, wherein said second face is adjacent said first face is adjacent in a longitudinal direction relative to said carrier tape.
Claim 16
Dependent Claim
13 words
A process in accordance with claim 12, wherein said material is resilient foam.
Claim 17
Dependent Claim
52 words
A method of impeding the bleeding from a minor surface wound, said method comprising positioning the pressure bandage of claim 1 circumjacent said wound such that said carrier tape is adhered to the skin circumjacent said wound and such that said compressible, resilient material is adjacent to and compressed against said wound.
