Abstract
An enteral feeding set for an enteral feeding pump having a control system for controlling operation of the pump to supply nutrient liquid to a patient through the enteral feeding set loaded in the pump, a source of electromagnetic radiation for emitting electromagnetic radiation and an electromagnetic radiation detector for receiving the electromagnetic radiation. The enteral feeding set includes a conduit for carrying nutrient liquid to a patient and a safety interlock device associated with the conduit adapted for mounting in the pump. The safety interlock device includes an electromagnetic radiation propagation affecting member formed to affect the propagation of electromagnetic radiation from the source of electromagnetic radiation through the safety interlock device and block visible light when properly loaded on the pump for directing the electromagnetic radiation from the source of electromagnetic radiation to the detector.
