Enteral Feeding Set and Interlock Device Therefor
First Claim
1. 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 feeding pump, the enteral feeding set comprising:
- a conduit for carrying nutrient liquid to a patient;
a safety interlock device associated with the conduit and adapted for mounting in the pump, the safety interlock device comprising 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, the electromagnetic radiation propagation affecting member directing the electromagnetic radiation from the source of electromagnetic radiation to the detector and blocking the detection of visible light by the pump when the conduit is properly loaded in the pump such that nutrient liquid flow to the patient is regulated by the pump.

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.
