摘要： A fluid warming device for an extracorporeal blood treatment apparatus, comprises: an outlet temperature sensor (31) operatively active at an outlet (22) of a fluid warming path (23) to detect a measured outlet temperature (To) of a fluid leaving the fluid warming device (18); an electronic control unit (29) operatively connected to the outlet temperature sensor (31). The electronic control unit (29) is configured to perform the following procedure: receiving, from the outlet temperature sensor (31) 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).

摘要： Blood treatment apparatus and methods of using the same are described herein that include two or more intermediate containers located between a treatment solution source and a port through which the treatment solution is to be delivered with the blood treatment apparatus. The weight of the intermediate containers is measured and used to control the refilling and emptying of treatment solution in the intermediate containers.

摘要： The invention relates to a blood line (108) comprising an infusion site (145) intended to inject into the line a solution comprising: —a first main channel (200) having a first passage section, —a second main channel (220) having a second passage section, —means for the formation (210) of a turbulence area located downstream from the first main channel, located upstream from the second main channel, these formation means comprising a first fluid passage means (224) defining a reduction (225) in the passage section and whose smallest passage section is smaller than the first passage section and smaller than the second fluid passage section, —a secondary channel (230) comprising an inlet (231) for letting in the solution and an outlet (232) in fluid communication with the first main channel or the means for the formation of a turbulence area or the second main channel.

摘要： An apparatus for extracorporeal treatment of fluid and a process of setting up a medical apparatus for the delivery or collection of fluids are disclosed. According to the apparatus and the process, a control unit (10) is configured calculate set values of two or more of the fluid flow rates by imposing that an emptying time of containers of fresh fluid (16, 20, 21, 26) and/or a filling time of a waste container is substantially same as, or multiple of, the emptying time of one or more of the other containers of fresh fluid.

摘要： An extracorporeal blood treatment apparatus, comprises: at least a pressure sensor (24,25) located in a respective measurement site on an extracorporeal blood circuit (6, 7); an electronic control unit (23) operatively connected at least to the pressure sensor (24, 25). The electronic control unit (23) is configured to perform at least the following procedure: receiving from the pressure sensor (24, 25) a signal correlated to a measured blood pressure (P1measured, P2measured) in the measurement site; correcting the blood measured pressure (P1measured, P2measured) through a mathematical correction model to obtain a blood actual pressure (Pinlet, Poutlet) in a reference site other than the measurement site. Between the reference site and the measurement site, a circuit section and, optionally, at least one additional device (18, 27, 28) is/are positioned. The mathematical correction model is a model of a pressure drop in the circuit section and, optionally, in the additional device (18, 27, 28).
