Abstract
Abstract A medical splint apparatus, useful for treatment of crush syndromes, an inflatable splint body adapted to be inflated by a working fluid received thereinside, and a heat exchange structure including an external vessel and an internal vessel received inside the external vessel, the vessels communicating with each other and being provided with respective fluid pressure control valves, the vessels also communicating with the inflatable splint body, the external vessel being filled with a supply of the working fluid and the internal vessel being filled with a supply of a cooling agent, particularly solid carbonic acid.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
59 words
A medical splint apparatus, according to claim 1, wherein said inflatable splint body has an internal wall and an external wall, said walls being made of respective materials of different degrees of rigidity and being interconnected with each other, so that a tortuous fluid passage is formed therebetween, said passage being in fluid communication with said heat exchange structure.
Claim 2
Dependent Claim
31 words
A medical splint apparatus, according to claim 2, further including a set of selectively removable panels made of a thermally insulating material connected to said internal wall of said splint body.
Claim 3
Dependent Claim
66 words
A medical splint apparatus according to claim 1 further including a diaphragm-type pneumatic pump means operatively connected to said conduit means to accelerate flow of cooling working fluid supplied to said inflatable splint means, and further conduit means communicating between said inner vessel and said pump means, whereby a portion of the gas produced by sublimation of said solid carbonic acid selectively operates said pump means.
Claim 4
Dependent Claim
44 words
A splint according to claim 1, wherein said inner vessel includes valve means to control circulation rate of said working fluid and time of cooling, and said outer vessel includes valve means to provide immobolization and a given pressure in the inflatable splint means.
