Abstract
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.
Claims24
An infusion pump which flows medicinal fluid through a delivery tube of an infusion tubing set to a patient and which prevents the free flow of fluid through the delivery tube, the tubing set including a slide clamp having a opening through which the delivery tube extends, the opening including a non-occluding portion and an adjoining occluding portion, the non-occluding portion allowing fluid flow through the delivery tube when the delivery tube is located in the non-occluding portion, the occluding portion preventing fluid flow through the delivery tube when the delivery tube is located in the occluding portion, the slide clamp further including a release tab extending adjacent the non-occluding portion, the infusion pump comprising:
- a tubing channel which receives a first portion of the delivery tube;
- a pumping device operative in the tubing channel and with the delivery tubing to flow the fluid through the delivery tube;
- an anvil attached on one side of the tubing channel;
- a pivotal lever having a compression edge which moves from the side of the tubing channel opposite the anvil into adjacency with the anvil to compress the delivery tube against the anvil and prevent fluid flow through the delivery tube when the pivotal lever is pivoted into an occluding position, the compression edge also moves away from adjacency with the anvil to open fluid flow through the delivery tube when the pivotal lever is pivoted into a non-occluding position, the pivotal lever also having a release surface which when moved a sufficient distance pivots the pivotal lever to move from the occluding position to the non-occluding position;
- an access opening adapted to receive the release tab of the slide clamp upon insertion and to direct the release tab into contact with the release surface of the pivotal lever, the access opening accommodating insertion of the release tab to the sufficient distance to pivoted the pivotal lever from the occluding position to the non-occluding position;
- at least one tube support positioned adjacent to the access opening to contact and maintain the delivery tube in a stationary position during the insertion of the release tab to the sufficient distance;
- a lever lock mechanism to releasably hold the pivotal lever in the non-occluding position after the insertion of the release tab has moved the release surface of the pivotal lever the sufficient distance;
- and
- the tube support causes the delivery tube to move from the non-occluding portion of the slide clamp into the occluding portion of the slide clamp simultaneously with insertion of the release tab to the sufficient distance to pivot the pivotal lever to the non-occluding position.
An infusion pump which flows medicinal fluid through a delivery tube of an infusion tubing set to a patient and which prevents the free flow of fluid through the delivery tube, the tubing set including a slide clamp having a opening through which the delivery tube extends, the opening including a non-occluding portion and an adjoining occluding portion, the non-occluding portion allowing fluid flow through the delivery tube when the delivery tube is located in the non-occluding portion, the occluding portion preventing fluid flow through the delivery tube when the delivery tube is located in the occluding portion, the infusion pump comprising:
- a tubing channel which receives a first portion of the delivery tube;
- a pumping device operative in the tubing channel and with the first portion of the delivery tubing to flow the fluid through the delivery tube;
- an internal occlusion clamp which interacts with the delivery tube and which has an occluding position for occluding the delivery tube when the first portion of the delivery tube in the tubing channel is accessible to a user of the infusion pump and a non-occluding position for allowing fluid flow through the delivery tube when the first portion of the delivery tube in the tubing channel is not accessable to the user of the infusion pump;
- an access opening adapted to receive a portion of the slide clamp when manually inserted therein by the user of the infusion pump;
- a release actuator of the internal occlusion clamp which when actuated releases the internal occlusion clamp from the occluding position and moves the internal occlusion clamp to the non-occluding position, the release actuator located relative to the access opening for contact by the portion of the slide clamp inserted through the access opening, the release actuator becoming actuated by movement to a sufficient distance imparted from the portion of the slide clamp inserted through the access opening;
- at least one tube support positioned adjacent to the access opening to contact and maintain the delivery tube in a stationary position at the access opening during the insertion of the portion of the slide clamp to the sufficient distance;
- and
- the stationary position of the delivery tube maintained by tube support causes manual insertion of the portion of the slide clamp in the access opening to the sufficient distance to move the delivery tube from the non-occluding portion of the opening in the slide clamp into the occluding portion of the opening in the slide clamp simultaneously with actuating the release mechanism.
