FLUID WARMING DEVICE FOR AN EXTRACORPOREAL BLOOD TREATMENT APPARATUS AND METHOD FOR DETECTING A FLUID TEMPERATURE AT AN OUTLET OF A FLUID WARMING DEVICE FOR AN EXTRACORPOREAL BLOOD TREATMENT APPARATUS

Abstract: a fluid warming device for an extracorporeal blood treatment apparatus, comprises: an outlet temperature sensor () operatively active at an outlet () of a fluid warming path () to detect a measured outlet temperature (to) of a fluid leaving the fluid warming device (); an electronic control unit () operatively connected to the outlet temperature sensor (). the electronic control unit () is configured to perform the following procedure: receiving, from the outlet temperature sensor () a signal correlated to a measured outlet temperature (to); correcting the measured outlet temperature (to) through a correction model to obtain an actual fluid outlet temperature (tout); adjusting a heating power (ph) of heating elements to keep the actual fluid outlet temperature (tout) at a set reference temperature value (tset). the correction model is an empirical model of a measurement error (e) derived from a plurality of experimental data sets, the measurement error (e) being a difference between the measured outlet temperature (to) and the actual fluid outlet temperature (tout).
