Claim 32:
33. Fluid temperature control device configured to receive a fluid warming/cooling bag connected to an extracorporeal blood treatment apparatus, the fluid temperature control device comprising:
a casing delimiting a heating/cooling seat configured to accommodate a fluid warming/cooling bag that comprises a main portion delimiting a fluid path with an inlet and an outlet and a tab protruding from the main portion;
heating/cooling elements operatively active in the heating/cooling seat to heat/cool a fluid warming/cooling bag when accommodated in heating/cooling seat;
a presence detector operatively active at the heating/cooling seat to detect presence of a fluid warming/cooling bag accommodated in heating/cooling seat,
wherein the presence detector comprises a transmitter configured to emit a signal and a receiver configured to receive the signal, the transmitter and the receiver being positioned on a same side with respect to the heating/cooling seat and on a same side with respect to the fluid warming/cooling bag when the warming/cooling bag is in the heating/cooling seat;
a receiving surface configured to intercept the signal emitted by the transmitter when the fluid warming/cooling bag is not properly accommodated in the heating/cooling seat, the receiving surface being configured to reflect the signal along a first reflected path, wherein the receiver is spaced from said first reflected path such that the signal reflected along the first reflected path is not captured by the receiver;
wherein the heating/cooling seat comprises a recess configured to accommodate a tab of a fluid warming/cooling bag accommodated in the heating/cooling seat only when a fluid warming/cooling bag is properly accommodated in the heating/cooling seat,
wherein, when a fluid warming/cooling bag is properly accommodated in the heating/cooling seat, the fluid warming/cooling bag is positioned between the transmitter and the receiving surface and the tab is positioned between the transmitter and the receiving surface or covers the receiving surface,
wherein the signal is reflected by the tab.
