Abstract
Temperature control device for use in fluid-based hyper/hypothermia systems, comprising a connection unit for connecting the device to a local power network, and a fluid temperature control unit for heating or cooling a fluid. The device includes a power supply unit, by which electrical consuming components of the fluid temperature control unit are supplied with power, and which effects supply of the electrical consuming components with direct current.
Claims15
A method of running a perfusion hyper/hypothermia system including a temperature control device and a connection unit, wherein the temperature control device includes a fluid temperature control unit including a plurality of electrical consuming components, a supply pump to pump fluid, and a power supply unit, wherein the method of running the perfusion hyper/hypothermia system comprises:
- receiving an alternating current power input from a local power network through the connection unit;
- performing power conversions, using the power supply unit, from the alternating current power input to a plurality of direct current power outputs, such that each of the plurality of direct current power outputs is one of a constant mode output and a variable mode output and the plurality of direct current power outputs includes a first direct current power output and a second direct current power output;
- supplying the plurality of direct current power outputs to the supply pump and the plurality of electrical consuming components including a heater, a cooler, a temperature sensor, and a temperature controller, including supplying the first direct current power output to the supply pump and the second direct current power output to at least one of the heater and the cooler, to enable precise power control over the supply pump and each of the electrical consuming components such that the temperature control device and the local power network are decoupled to reduce network feedback and leakage currents;
- controlling the plurality of direct current power outputs to regulate a fluid temperature and a pumping rate;
- and
- circulating the fluid from a fluid container through a pipeline to outside of the temperature control device in the perfusion hyper/hypothermia system and back to the fluid container using the supply pump.
