    摘要： A cassette usable with an infusion pump includes a monolithic cassette body and a segment of resiliently deformable tubing for conveying a flow of liquid. The monolithic cassette body has an integrally formed free-flow protection device including a fixed pinch element and a deflectable pinch arm having a movable pinch element. The pinch arm normally resides in a closed position wherein the pinch elements cooperate to deform the tubing segment to stop flow. The pinch arm is resiliently deflectable away from the closed position to an open position permitting flow. Deflection of the pinch arm away from the closed position spring biases the pinch arm for automatic return to the closed position. The pinch arm may be moved to the open position by operating a door of the pump when the cassette is loaded in the pump, and manually for priming when the cassette is not loaded in the pump.

    摘要： An infusion pump has an optical cassette detection system for determining whether or not a cassette of an administration tubing set is properly loaded in the pump. Operation of the pump may be enabled or disabled based on a determination of the cassette detection system. The cassette detection system includes a light emitter and a corresponding photosensitive detector aligned along an optical axis, and window carried by the cassette. When the cassette is properly loaded in the pump, a light beam from the emitter enters the window, where a portion of the beam is absorbed and another portion of the beam is transmitted for receipt by the detector. The detector signal is evaluated by signal evaluation electronics to determine if the cassette is loaded. The determination may be based on an expected attenuation of the light beam corresponding to a predetermined light absorptance property of the window.

    摘要： In an infusion pump operable to deliver fluid to a patient at a programmed therapy flow rate, air-in-line sensing is improved by commanding the pumping mechanism to deliver a bolus volume of fluid at a flow rate higher than the therapy flow rate when an uninterrupted volume of air is detected that exceeds a first threshold. In many cases, the bolus will be effective to clear microbubbles from an observation zone of the air-in-line sensor to avoid an air-in-line alarm condition. If the uninterrupted volume of air continues to grow beyond a second threshold in spite of the bolus, then an alarm may be triggered. The invention reduces false alarms.

    摘要： An anti-free-flow mechanism includes an occluder mechanism which is disposed along a segment of tubing. The occluder mechanism is normally in a biased closed position, but may be moved into an open position by moving an engagement member into engagement with the tubing segment to deform the tubing segment and open a flow channel. Unless force is applied to keep the engagement member in contact with the tubing segment, the tubing will return to the first, closed position.
