Tubing occlusion clip

Claim 1

A tubing occlusion clip comprising: an end wall portion; first and second arms joined to spaced regions of the end wall portion and being resiliently movable toward each other; a closing wall portion joined to said first arm and extendible to said second arm whereby said arms can cooperate with said wall portions to form a closed loop; said arms being adapted to have a tube extend therebetween; first and second clamping members carried by the first and second arms, respectively, and adapted to have the tube extend between the clamping members; said arms being relatively movable toward each other to a clamping position in which the tube is clamped between said clamping members to at least restrict flow through the tube and relatively movable away from each other to a releasing position in which the clamping members impose a lesser restriction to flow through the tube; said second arm terminating in a cam and having a shoulder and an outer surface at opposite ends of the cam; said closing wall portion having a cam follower and a shoulder at the inner end of said cam follower; said shoulders being in engagement in the releasing position whereby the arms are positively locked in the closed loop in the releasing position and said cam and said cam follower being in engagement in said releasing position whereby inward movement of the second arm moves the arms to the clamping position; and said outer surface engaging the shoulder of the closing wall portion in the clamping position to releasably retain the arms in the clamping position.
