Abstract:
A cardiopulmonary life support system comprising:a) a housing defined by a top side, a bottom, a rear side, and an inner periphery; b) first and second tubes adjacent to each other in the housing, wherein the first and second tubes each have an input port and an output port; c) an alternating member attached to the housing and disposed between the first and second tubes, wherein the alternating member alternately squeezes the first and second tubes; d) a valve formed in said each input and output port to prevent a reverse stream in the first and second tubes; e) a solid tube support fitted between said each tube and the inner periphery of the housing; and f) a shaft substantially parallel to the tubes, wherein the shaft has a top portion rotatably attached to the top side, a mid portion fixedly attached to the alternating member, and a bottom portion rotatably passing through the bottom side of the housing, whereby an angular reciprocal rotation of the shaft enables the alternating member to alternately squeeze the first and second tubes.
