摘要：
An infusion pump (10) has an optical detection system (50) for determining whether or not a cassette (14) 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 optical cassette detection system includes a light emitter (52) directing a light beam along an optical axis to a corresponding light detector (54) aligned on the optical axis. The cassette detection system also includes a tab carried by the cassette and arranged such that when the cassette is properly loaded in the pump, the tab intersects the optical axis and blocks at least a portion of the light beam from reaching the detector. The detector signal is evaluated by signal evaluation electronics to determine if the detector signal level is below a predetermined threshold, indicating presence of the cassette.
