Slide clamp and tubing set for an infusion pump

摘要

An infusion pump for metering fluid flow through an delivery tube of an infusion tubing set has an internal occlusion clamp which clamps the delivery tube to prevent the free flow of fluid through the tube when access to the delivery tube in the infusion pump is possible. To release the delivery tube from the infusion pump, a slide clamp is manually used to release the occlusion clamp to an open, non-occluding position while simultaneously occluding the delivery tube to prevent the free flow of fluid.

主权项

1. A slide clamp for use with an infusion tubing set having a delivery tube and with an infusion pump comprising an internal occlusion clamp having an occluding position which occludes and thereby prevents fluid flow through the delivery tube located within the infusion pump and a non-occluding position which does not occlude and thereby permits fluid flow through the delivery tube, the slide clamp adapted for selectively occluding the delivery tube at a position located outside of the infusion pump by a single manual movement of the slide clamp which simultaneously also moves the internal occlusion clamp from the occluding position to the non-occluding position, comprising:
a body having a length in a longitudinal dimension which extends from a proximal end to a distal end, the body having a width in a lateral dimension perpendicular to the longitudinal dimension, the width being less than the length, the body having a height in a dimension perpendicular to the longitudinal and lateral dimensions, the height being less than the width, the height of the body at the proximal end being greater than the height of the body at the distal end; a non-occluding opening defined in the body and adapted to receive the delivery tube outside of the infusion pump, the non-occluding opening having a width in the lateral dimension that is insufficient to pinch and occlude the delivery tube when the delivery tube is located in the non-occluding opening; an occluding opening defined in the body and also adapted to receive the delivery tube outside of the infusion pump, the occluding opening extending proximally from the non-occluding opening, the occluding opening having a width in the lateral dimension that is sufficient to pinch and occlude the delivery tube upon movement of the delivery tube into the occluding opening with the single manual movement of the slide clamp which simultaneously also moves the occlusion clamp from the occluding position to the non-occluding position; and a release tab extending distally in the longitudinal dimension at the distal end of the body, the release tab having a width which is less than the width of the body proximal of the release tab, the release tab adapted for operative contact with the internal occlusion clamp to move the internal occlusion clamp from the occluding position to the non-occluding position with the single manual movement of the slide clamp.
