Abstract: A method of operating an enteral feeding pump to deliver fluid through a pump set, the method comprising determining with a controller of the enteral feeding pump if an occlusion exists in the pump set based on the controller monitoring a sensor signal from a sensor indicative of a rotational position of a rotor of the pump during operation of a motor of the pump to rotate the rotor at a reduced output less than a feeding output for rotating the rotor to produce fluid flow in the pump set during a feeding cycle, the motor operating at the reduced output for a shorter period of time than the feeding output.

A sensor is arranged with respect to a pumping device to produce a signal indicative of pressure in the feeding set. A control circuit that may receive the sensor signal from the sensor indicative of the pressure in the feeding set may also control operation of the pumping device. The control circuit is configured to operate the pumping device in an operational state, and in a reset state subsequent to the operational state in which the pumping device does not produce a pumping action and the pumping device is moved to a position in which the pumping device does not block the feeding set to permit fluid flow in a backflow direction opposite to the patient direction thereby relieving any built up pressure in the feeding set downstream of the pumping device.

Abstract: Detection of fluid conditions in a section of tube of an administration set. A light source is positioned adjacent to the tube to transmit an infrared light through the tube and any fluid therein. A light sensor senses the infrared light transmitted through the tube and generates an output signal. A frequency of the output signal is a function of an intensity of the light transmitted through the tube. A processor receives and determines the frequency of the output signal, and compares the determined frequency to threshold frequency values to determine whether fluid is in the tube. The processor also monitors the generated output signal to determine if the frequency of the output signal changes over a predetermined period of time, and determines whether fluid is flowing in the tube as a function of the determined change in frequency.
