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 operatively connected to the control system of the pump for emitting electromagnetic radiation, and an electromagnetic radiation detector operatively connected to the control system for receiving the electromagnetic radiation and providing an indication to the control system that the feeding set is properly loaded in the pump. The feeding set includes a conduit for carrying nutrient liquid to a patient. A safety interlock includes a light pipe for providing a passage of the electromagnetic radiation from the source of electromagnetic radiation to the electromagnetic radiation detector only when the safety interlock is loaded in the pump such that nutrient liquid flow to the patient is regulated by the pump.
