Claim 19:
20. The multi-junctional bleeding simulator of claim 19, wherein the multi-junctional attachment unit includes an adjustable auxiliary strap configured to wrap around the neck and alternately the torso of the wearer, and an adjustable limb strap configured to wrap around the each limb of the wearer;
wherein the adjustable auxiliary strap includes a manual release couple, a neck strap configured to toollessly couple to the manual release couple and to wrap about the neck of the wearer when coupled, and an extended strap configured to alternately toollessly couple to the manual release couple and to wrap about the torso of the wearer when alternately coupled, respectively;
wherein the auxiliary strap further includes a first hook and loop fastener half fixed to an end opposite of the manual release couple;
wherein the neck strap includes a first reciprocal couple fixed at a first end of the neck strap, and a first reciprocal hook and loop fastener half fixed to a second end of the neck strap opposite the first end of the neck strap, the first reciprocal couple configured to mate with the manual release couple, and the first reciprocal hook and loop fastener configured to mate with the first hook and loop fastener half;
wherein the extended strap includes second reciprocal couple fixed at first end of the extended strap, and a second reciprocal hook and loop fastener half fixed to a second end of the extended strap opposite the first end of the extended strap, the second reciprocal couple configured to alternately mate with the manual release couple, and the second reciprocal hook and loop fastener configured to alternately mate with the first hook and loop fastener half, respectively with the neck strap;
wherein the multi-junctional attachment unit further includes a puncture and cut resistant protective layer positioned between the wearer and the simulated wound, and configured to inhibit injury to the wearer from medical instruments during use of the multi-junctional bleeding simulator;
wherein the multi-junctional attachment unit further includes a padding layer positioned to be in contact with the wearer, and configured to decrease the movement of the multi-junctional bleeding simulator when worn by the wearer;
wherein the outer layer and the inner layer of the simulated wound are configured to substantially rest against each other in a relaxed state, minimizing a volume of the dynamic cavity, and further configured to be deformable away from each other upon application of a physical force or pressure, dynamically increasing said volume of the dynamic cavity;
wherein the simulated blood vessel is sufficiently flexible to be compressed closed upon performance of the hemorrhage control procedure;
wherein the simulated wound is further configured to reduce or stop the flow of the simulated blood upon compressing closed the simulated blood vessel;
wherein the simulated wound is further configured to reduce or at least substantially stop the simulating bleeding upon at least one of performance of a ligation procedure on the simulated blood vessel, performance of a compression procedure on or proximate the simulated blood vessel, and compacting the simulated wound cavity with gauze;
wherein the blood plumbing system further includes a blood feed line fluidly coupled to the simulated blood vessel and configured to communicate the simulated blood into the simulated blood vessel, a bypass valve fluidly coupled to the blood feed line and configured to provide an alternate low pressure return path in response to a backpressure in the simulated blood vessel, the blood plumbing system further including a blood return line fluidly, fluidly coupled to the bypass valve and configured to communicate the simulated blood out of the simulated wound along the alternate low pressure return path; and
wherein the bypass valve has a fully open state triggered by a full bypass backpressure, a partially open state triggered by a cracking backpressure, and a normally-closed state, the full bypass backpressure corresponding to the hemorrhage control procedure being properly performed to stop bleeding, and the cracking backpressure corresponding to the hemorrhage control procedure being properly performed to slow bleeding.
