Abstract
An apparatus for delivering a fluid to a subject through infusion tubing (22). The apparatus includes a tube cassette (20) for receiving the infusion tubing. The tube cassette has an anti-free-flow valve (26) configured to (i) occlude the infusion tubing, and (ii) be actuated by a force external to the tube cassette to terminate the occlusion of the infusion tubing. The tube cassette is configured to be removably coupled to a pump (24). The pump is configured to, as part of a pumping cycle for delivering the fluid to the subject, repeatedly (a) actuate the anti-free-flow valve to terminate the occlusion of the infusion tubing, and subsequently (b) release the anti-free-flow valve to occlude the infusion tubing. Other applications are also described.

An apparatus for delivering a fluid to a subject through infusion tubing, the apparatus comprising:
- (A) a tube cassette configured to receive the infusion tubing and comprising an anti-free-flow valve configured to:
- (i) occlude the infusion tubing, and
- (ii) be actuated by a force external to the tube cassette to terminate the occlusion of the infusion tubing, upon the force external to the tube cassette being applied at a location along the infusion tubing longitudinally displaced from a site where the anti-free-flow valve occludes the infusion tubing;
- and
- (B) a pump:
- (i) the tube cassette being configured to be removably coupled to the pump, the pump comprising a pressing surface configured to press on the infusion tubing when the tube cassette is coupled to the pump, and
- (ii) the pump being configured to, as part of a pumping cycle for delivering the fluid to the subject, repeatedly (a) actuate the anti-free-flow valve to terminate the occlusion of the infusion tubing, and subsequently (b) release the anti-free-flow valve to occlude the infusion tubing,
- wherein the anti-free-flow valve is configured to occlude the infusion tubing by moving in the same direction as the direction in which the pressing surface presses on the infusion tubing.
