Abstract
Abstract A tubing occlusion clip comprising a first wall portion, first and second arms joined to spaced regions of the first wall portion and a closing wall portion joined to the first arm and extendible to the second arm such that the arms cooperate with the wall portions to form a closed loop. The wall portions have openings, and a tube is coupled to the first wall portion and extends across the closed loop and through the opening of the closing wall portion. First and second clamping members are carried by the first and second arms, respectively, and they are adapted to have the tube extend therebetween. The arms are relatively movable toward each other to a clamping pesition in which the tube is clamped between the clamping members and relatively movable away from each other to a releasing position. Interlocking members are provided on the closing wall portion and the second arm for positively locking the closed loop against opening when the arms are in the releasing position.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
217 words
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 whreby said arms can cooperate with said wall portions to form a closed loop; said wall portions having openings therein whereby a tube can extend from the opening in the end wall portion and across said closed loop into the opening of the closing wall portion; firct and second clamping members carried by the first and second arms, respectively, and arranged such that a tube extending between the openings in the wall portions passed between the clamping members; said arms being relatively movable toward each other to a clamping position in which a tube extending between the openings in the wall portions 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 or no restriction to flow through the tube; means for retaining the clip in a closed loop configuration in both the clamping position and the releasing portion; and means for releasably retaining the arms in the clamping - position.
Claim 2
Dependent Claim
217 words
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 whreby said arms can cooperate with said wall portions to form a closed loop; said wall portions having openings therein whereby a tube can extend from the opening in the end wall portion and across said closed loop into the opening of the closing wall portion; firct and second clamping members carried by the first and second arms, respectively, and arranged such that a tube extending between the openings in the wall portions passed between the clamping members; said arms being relatively movable toward each other to a clamping position in which a tube extending between the openings in the wall portions 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 or no restriction to flow through the tube; means for retaining the clip in a closed loop configuration in both the clamping position and the releasing portion; and means for releasably retaining the arms in the clamping - position.
Claim 3
Dependent Claim
129 words
A tubing occlusion clip according to claim 1, wherein said second arm terminates in a cam and has a shoulder and an outer surface at opposite ends of the cam; said losing wall portion has a cam follower and a shoulder at the inner end of said cam follower; said shoulders being in engagement in the releasing position so that the arms are positively locked in the closed loop configuration in the releasing position and said cam and said cam follower being in engagement in said releasing position such that inward movement of the second arm moves the clip to the clamping position in which said other surface engages the shoulder of the Closing wall portion in the clamping position to releasably retain the arms in the clamping position.
Claim 4
Dependent Claim
57 words
A tubing occlusion clip according to claim 1 or claim 2, wherein the closing wall portion includes a member extending across the opening thereof and a tab on the second arm is extendible into the opening of the closing wall portion and engageable with said member to at least assist in locking the closed loop against opening.
Claim 5
Dependent Claim
40 words
A tubing occlusion clip according to any one of claims 1 to 3, wherein said tubing occlusion clip is integrally molded of plastic and said end wall portion and said arms are relatively rigid and integrally joined by resilient hinges.
Claim 6
Dependent Claim
51 words
A tubing occlusion clip according to any one claims 1 to 4, including a hub carried by the end wall portion, projecting cutwardly of the closed loop, and having the opening in the first wall portion extending therethrough and mechanical means on the hub for coupling the hub to another member.
Claim 7
Dependent Claim
36 words
A tubing occlusion clip according to any one of claims 1 to 5 including a tube coupled to the end wall portion at the opening in said end wall portion and passing between the clamping members.
Claim 8
Dependent Claim
37 words
A tubing occlusion clip according to claim 6, wherein Said tube is formed integrally with said end wall portion such that a continuous passage is formed by the opening in said end wall portion and said tube.
Claim 9
Dependent Claim
44 words
A tube occlusion clip according to any one of claims 1 to 7, vherein the end wall has a tubular projection extending inwardly of the closed loop and the tube to be occluded is received within the tutulan projection or is integzally formed therewith.
