Patent ID: 8758297

Claim:
A medical fluid pumping system comprising: a medical fluid pumping machine comprising a pump; fluid circuitry comprising tubing that can be connected to the pump in a manner such that the pump can move a medical fluid through the tubing of the fluid circuitry; and a sensor assembly comprising: a housing defining a slot to retain a portion of tubing of the fluid circuitry; a non-invasive fluid temperature sensor mounted to the housing and configured to detect a temperature of medical fluid in the portion of tubing of the fluid circuitry when the portion of tubing is disposed in the slot and the medical fluid is flowing through the portion of tubing; and an ambient air temperature sensor mounted to the housing; wherein the medical fluid pumping machine comprises a control unit that is in communication with the non-invasive fluid temperature sensor and the ambient air temperature sensor; wherein the control unit comprises a look-up table that provides a corrected medical fluid temperature for each of multiple different combinations of temperatures of medical fluid detected by the non-invasive fluid temperature sensor and temperatures of ambient air detected by the ambient air temperature sensor.
