Abstract

Occlusion sensor systems and methods of using the occlusion sensor systems are provided. In a general embodiment, the present disclosure provides a sensor device includes a tube and an infra-red reflective sensor comprising an infra-red light emitter and an infra-red phototransistor receiver or photo-diode. The infra-red reflective sensor and the infra-red phototransistor receiver or photo-diode are positioned at or near the tube so that an infra-red light can be transmitted to a portion of the tube and at least a portion of the infra-red light reflected off the portion of the tube can be detected by the infra-red phototransistor receiver or photodiode.
