Abstract
Abstract There is disclosed a limb for a first aid training dummy molded of an integral skin foam. The skin of the foam is shaped to define a simulated wound. Molded into the foam and extending from outside the limb and into communication with the simulated wound is a flexible plastic tube for supplying simulated blood. Aligned with the tube is a simulated bone which permits pressure to be applied to the wound or the tube to block the flow of simulated blood. The tube is molded into the limb by a technique which includes supporting the tube on a support wire during the molding process and thereafter removing the wire from the tube.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
169 words
The method of forming a simulated wound in a training dummy which comprises: providing a first concave mold member defining on its inner surface a raised, wound defining, projection; providing, adjacent said projection, means for temporarily supporting the end of a wire; passing a relatively stiff support wire through a length of resilient tubing with the first and second ends of said wire extending; respectively, from the first and second ends of said tubing; positioning the wire stiffened tubing with the first end of said wire supported by said temporary support means and the second ends of said wire and tubing outside the first mold member; positioning a second concave mold member against said first mold member to define therewith a mold cavity approximating the shape of a human body member; filling said cavity with a curable molding composition; curing said composition to form a simulated human body member; removing said support wire from said tubing; and removing said simulated body member from said first and second mold members.
Claim 2
Independent Claim
169 words
The method of forming a simulated wound in a training dummy which comprises: providing a first concave mold member defining on its inner surface a raised, wound defining, projection; providing, adjacent said projection, means for temporarily supporting the end of a wire; passing a relatively stiff support wire through a length of resilient tubing with the first and second ends of said wire extending; respectively, from the first and second ends of said tubing; positioning the wire stiffened tubing with the first end of said wire supported by said temporary support means and the second ends of said wire and tubing outside the first mold member; positioning a second concave mold member against said first mold member to define therewith a mold cavity approximating the shape of a human body member; filling said cavity with a curable molding composition; curing said composition to form a simulated human body member; removing said support wire from said tubing; and removing said simulated body member from said first and second mold members.
Claim 3
Dependent Claim
13 words
The method of claim 1 wherein said temporary support means comprises an eyelet.
Claim 4
Dependent Claim
14 words
The method of claim 1 wherein said molding composition comprises an integral skin foam.
Claim 5
Dependent Claim
60 words
An artificial body member which comprises: a simulated bone; an integral skin foam surrounding said simulated bone and shaped to resemble a human body member, the external surface of said foam defining a simulated wound; and a flexible tube molded in said foam with a first end communicating with said wound and a second end extending outwardly from said foam.
Claim 6
Dependent Claim
60 words
An artificial body member which comprises: a simulated bone; an integral skin foam surrounding said simulated bone and shaped to resemble a human body member, the external surface of said foam defining a simulated wound; and a flexible tube molded in said foam with a first end communicating with said wound and a second end extending outwardly from said foam.
Claim 7
Dependent Claim
20 words
The member of claim 4 wherein said flexible tube is positioned to be pinched between said wound and said bone.
