Medical training kits and methods to simulate treatment of uncontrolled hemorrhage

A gellable simulated liquid blood which comprises:

• at least one gellable component which comprises an aqueous acidic chitosan solution, wherein the chitosan is present in the simulated blood in an amount between about 0.6 to about 2.0 wt. %;
• at least one colorant in an amount sufficient to mimic coloration of whole mammalian blood;
• and
• optionally at least one additive selected from the group consisting of viscosity modifiers, tactile agents and scent modifiers, wherein
• in response to the gellable simulated liquid blood being brought into contact with a gelling agent, the at least one gellable component is caused to desolubulize, polymerize, complex, precipitate and/or cross-link so as to form a mass of semi-solid or solid material to thereby simulate blood clotting.

A simulated hemostatic dressing which comprises:

• a fabric substrate;
• and
• a simulated hemostatic component comprising a gelling agent carried by the fabric substrate, wherein
• the gelling agent is present in an amount between about 10 wt. % to about 80 wt. %, based on the weight of the fabric substrate;
• and wherein
• the gelling agent is at least one compound selected from the group consisting of sodium tripolyphosphate (NaTPP), calcium salts, β-glycerophospate, sodium bicarbonate, sodium carbonate, sodium citrate, citric acid, and Rose Bengal, and wherein
• the gelling agent causes gelling of a simulated blood component comprising a gellable component comprising chitosan and/or alginate by causing the gellable component to desolubulize, polymerize, complex, precipitate and/or cross-link so as to form a semi-solid or solid mass of the gellable component in response to physical contact between the simulated blood component and the gelling agent thereby simulating clotting of natural whole blood.
