Fluid temperature control device for an extracorporeal blood treatment apparatus and extracorporeal blood treatment apparatus

Fluid temperature control device for an extracorporeal blood treatment apparatus, comprising:

• a casing delimiting a heating/cooling seat configured to accommodate a fluid warming/cooling bag that is configured to be connected to an extracorporeal blood treatment apparatus;
• a heating/cooling element operatively active in the heating/cooling seat to heat/cool a fluid warming/cooling bag accommodated in the heating/cooling seat;
• and
• two presence detectors configured to detect if and which type of fluid warming/cooling bag is accommodated in the heating/cooling seat of the fluid temperature control device,
• wherein a first presence detector of the two presence detectors is operatively active at the heating/cooling seat and configured to detect the presence of a fluid warming/cooling bag accommodated in the heating/cooling seat,
• wherein the first presence detector comprises a first transmitter configured to emit a first signal and a first receiver configured to receive the first signal,
• wherein the first receiver is positioned with respect to the first transmitter to selectively receive the first signal emitted by the first transmitter after the first signal is reflected,
• wherein a second presence detector of the two presence detectors is operatively active at the heating/cooling seat and configured to detect presence of a fluid warming/cooling bag accommodated in the heating/cooling seat,
• wherein the second presence detector comprises a scowl transmitter con wired to emit a second signal and a second receiver configured to receive the second signal,
• wherein the second receiver is positioned with respect to the second transmitter to selectively receive the second signal emitted by the second transmitter after the second signal is reflected,
• wherein the first presence detector and the second presence detector are placed side by side.

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.
