PUMPING APPARATUS WITH SECURE LOADING FEATURES
First Claim
1. A pumping apparatus and pump set for use to deliver a supply of liquid to a patient, the pump set comprising a conduit for the liquid and a safety interlock device associated with the conduit, the pumping apparatus comprising:
- a pumping device operable to act on the pump set to drive flow of the liquid in the pumpset;
a control system for controlling operation of the pumping device;
at least two sensors operatively connected to the control system of the pumping apparatus, a first of said sensors being adapted for identifying the safety interlock device in a loaded position of the device and a second of said sensors being adapted for detecting a fault condition associated with positioning of the safety interlock device.

Abstract
A pumping apparatus and pump set for use to deliver a supply of liquid to a patient. The feeding set has a conduit for the nutrient liquid and a safety interlock device associated with the conduit. The pumping apparatus has a pumping device and a control system for controlling operation of the pump. An electromagnetic radiation source is operatively connected to the control system of the pump for emitting an electromagnetic radiation signal in a direction for striking the safety interlock device of the feeding set. The safety interlock device being adapted to affect the direction of the electromagnetic radiation. An electromagnetic radiation detector is operatively connected to the control system for receiving the electromagnetic radiation signal when the direction is affected by the safety interlock device, and provides an indication to the control system that the feeding set conduit is properly positioned in the feeding pump.
