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.
Claims20
A 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 to heat and/or cool a fluid in a surgical environment during heart surgery including a power supply unit that supplies electrical consuming components of the fluid temperature control unit with direct current and power of up to 3500 watts.
A temperature control device for use in fluid-based hyper/hypothermia systems, comprising:
- a connection unit adapted for connecting the device to a local power network;
- a power supply unit that receives an alternating current power from the local power network and converts the alternating current power from the local power network to a direct current power;
- and
- a fluid temperature control unit to heat and/or cool a fluid, the fluid temperature control unit including a heater, a cooler, a supply pump, a temperature sensor, and a temperature controller;
- wherein each of the heater, the cooler, the supply pump, and the temperature controller are coupled to the power supply unit and receive the direct current power.
A temperature control device for use in fluid-based hyper/hypothermia systems, comprising:
- a connection unit that connects the temperature control device to a local power network;
- a fluid temperature control unit including a plurality of electrical consuming components, the plurality of electrical consuming components including a pump and a heater and/or cooler for heating and/or cooling a fluid;
- a power supply unit connected to the connection unit to receive alternating current power from the local power network, the power supply unit connected to the fluid temperature control unit to supply direct current power to the plurality of electrical consuming components;
- wherein when the power supply unit receives an alternating current power from the local power network the power supply unit converts the alternating current power from the local power network to direct current power;
- and
- wherein the power supply unit provides the direct current power to the pump and the heater and/or cooler.
A temperature control device for use in fluid-based hyper/hypothermia systems, comprising:
- a connection unit for connecting the device to any one of a plurality of local power networks providing alternating current power, wherein each of the plurality of local power networks provides alternating current power at a different frequency and/or different voltage;
- a fluid temperature control unit that heats or cools a fluid in a surgical environment during heart surgery including:
- a fluid container;
- a heater and/or cooler for heating and/or cooling fluid in the fluid container;
- a pump that transfers fluid between the fluid container and the fluid-based hyper/hypothermia system;
- and
- a power supply unit that converts the alternating current power from the local power network to a direct current power to supply the heater and/or cooler and the pump of the fluid temperature control unit with direct current power.
