Flexible tubing occlusion assembly
First Claim
1. An occlusion assembly for occluding a pair of collapsible tubes of a medical infusion device, comprising:
- a first occluding member constructed and positioned to controllably occlude or release occlusion of a first tube of the pair of collapsible tubes, and a second occluding member constructed and positioned to controllably occlude or release occlusion of a second tube of the pair of collapsible tubes;
the first occluding member and the second occluding member being positioned next to each other and between the first and the second tubes such that a space is defined between the first occluding member and the second occluding member;
a spreader positioned within the space and configured to slide along a side of each occluding member from a first position to a second position, wherein sliding from the first position to the second position causes the spreader to force at least a portion of the first and the second occluding members to move apart from each other and force a tube-contacting portion of each of the first and the second occluding members against the respective first and second tube to occlude the first and the second tubes;
an automatic actuator operatively coupled to the spreader to slide the spreader to cause the first and the second occluding members to move from the occluding position to the non-occluding position; and
an override mechanism operatively coupled to the spreader to slide the spreader to cause the first and the second occluding members to move from an occluding position to a non-occluding position upon manual operation of the override mechanism by a user.

Abstract
An occlusion assembly for compressing a pair of collapsible tubes comprises an occluding member for each tube. Each occluding member is forced into an occluding position by a spreader positioned within a space between the occluding members that slides along a side of each occluding member causing a tube-contacting portion of each occluding member to compress the collapsible tubes. A main spring may be included that urges the spreader toward the distal ends of the occluding members and into an occluding position. The spreader may be moved against the biasing force of the main spring into a non-occluding position near the proximal ends of the occluding members either manually through a button and linkage assembly coupled to the spreader, or by an automatic actuator coupled to the spreading element.
