Claim Text:
1. An apparatus comprising: a single chamber pneumatic tourniquet having a length and a width, the single chamber pneumatic tourniquet length greater than the single chamber pneumatic tourniquet width; a pneumatic barrier having a first side in contact adjacency with the single chamber pneumatic tourniquet; a single chamber tissue compression member in contact adjacency with a second side of said pneumatic barrier, the single chamber tissue compression member having a length and a width, the single chamber tissue compression member length greater than the single chamber pneumatic tissue compression member width, the single chamber tissue compression member running substantially parallel to the single chamber pneumatic tourniquet along its entire length, the single chamber pneumatic tourniquet configured for surrounding substantially an entirety of a limb of a patient and in which the apparatus includes two and only two chambers, the single chamber pneumatic tourniquet and the single chamber tissue compression member; and a pneumatic gate in fluid communication with each of the single chamber pneumatic tourniquet and the single chamber tissue compression member, wherein the pneumatic gate promotes an inflation of the tissue compression member only after full inflation of the single chamber pneumatic tourniquet forms a tourniquet, where in the tourniquet precludes return blood flow through the patient's veins below the formed tourniquet, prior to inflation of the single chamber tissue compression portion, and wherein the pneumatic gate is formed between the single chamber pneumatic tourniquet and the single chamber tissue compression member by an aperture only, and further wherein the width of the single chamber pneumatic tourniquet is less than the width of the single chamber tissue compression member such that an internal volume of the single chamber pneumatic tourniquet is less than an internal volume of the single chamber tissue compression member.
