Abstract

An occlusion assembly for compressing a pair of collapsible tubes comprises a frame comprising a tubing guide configured for positioning the collapsible tube. The occlusion assembly also comprises a tubing occluder mounted to the frame with an occluding member constructed and positioned to controllably occlude or release occlusion of the collapsible tube. A door mounted to the frame is positioned to cover at least a portion of the collapsible tube and tubing occluder when closed and provide user access when open. The assembly includes a retainer mechanism engaged by the door when the door is closed to permit operation of the tubing occluder when the door is closed and retain the tubing occluder in a non-occluding configuration when the door is opened.

Claims

1-4. -4. (canceled)

5. An occlusion assembly for occluding at least one collapsible tube of a medical infusion device, comprising:

a frame comprising a tubing guide configured for positioning the collapsible tube;

a tubing occluder mounted to the frame and comprising an occluding member constructed and positioned to controllably occlude or release occlusion of the collapsible tube;

a door hingeably mounted to the frame and positioned to cover at least a portion of the collapsible tube and tubing occluder when in a closed position and to provide user access to the collapsible tube when in an open position; and

a retainer mechanism engaged by the door when the door is in the closed position and configured to permit operation of the tubing occluder to occlude or release occlusion of the collapsible tube when the door is in the closed position and configured to engage and retain the tubing occluder in a non-occluding configuration when the door is opened while the tubing occluder is positioned in the non-occluding configuration.

16. The occlusion assembly of claim 5, wherein the tubing occluder comprises a carriage assembly slidably mounted to the frame, and wherein the carriage assembly

i. is operatively coupled to an actuator that is configured to cause sliding motion of the carriage assembly,

ii. is operatively coupled to an occluding member engaging element configured to move the occluding member into an occluding position or permit the occluding member to move into a non-occluding position upon sliding motion of the carriage assembly,

iii. comprises a latching pin.

17. The occlusion assembly of claim 16, further comprising a retention member movably mounted to the frame, the retention member comprising a surface configured and positioned to be engaged by a portion of the door when the door is in the closed position, the retention member further comprising a latching pin receiving hole sized and positioned to allow substantially unrestricted entry of the latching pin into the latching pin receiving hole upon sliding motion of the carriage assembly in a direction to permit the occluding member to move into the non-occluding position and exit of the latching pin from the latching pin receiving hole upon sliding motion of the carriage assembly in a direction move the occluding member into the occluding position when the door is in the closed position, wherein the retention member is biased for movement upon opening of the door to cause the latching pin receiving hole to move into engaging and retaining contact with the latching pin when the carriage assembly is positioned in its non-occluding position when the door is open.
