Apparatus for applying a desired temperature and pressure to an injured area

A portable apparatus for the treatment of injuries which may be coupled to a portable source of compressed gas, the apparatus comprising:

• a first layer of flexible material;
• a second layer of flexible material coupled to the first layer of flexible material so that a space between the first and second layers forms an inflation chamber;
• a third layer of flexible material coupled to the first and second layers, said coupling between the second and third layers defining a space between the second and third layers, wherein the space between the second and third layers is in fluid communication with the inflation chamber at an outlet and wherein the space between the second and third layers defines a fluid channel which extends along a predetermined path from an inlet port to the outlet, wherein the fluid channel is formed so that a gas entering the apparatus at the inlet will travel along the fluid channel through the outlet into the inflation chamber;
• a plurality of spacer members coupled to one of the second and third layers, the spacer members maintaining the separation between the second and third layers so that the fluid channel remains unobstructed even when the apparatus is folded or wrapped around an injured area;
• and
• a relief valve coupled to the inflation chamber, wherein the relief valve operates to maintain the pressure within the inflation chamber below a predetermined pressure.
