Description
- This application is a continuation of U.S. application Ser. No. 13/441,603, which claims priority to German Application No. 10 2011 016 508.8, filed Apr. 8, 2011, which are herein incorporated by reference in their entirety.
- The invention relates to a temperature control device for use in fluid-based hyper/hypothermia systems.
- A fluid-based hyper/hypothermia system is disclosed, for example, in DE 696 34 572 T2. Fluid-based hyper/hypothermia systems that use a temperature-controlled fluid to raise the temperature of a human or animal body, body part or organ to above the normal core body temperature or to lower it to below the normal core body temperature require a temperature control device that provides a temperature-controlled fluid to accomplish the desired change in body temperature. The temperature of the fluid must be controlled in the temperature control device in accordance with the quantity of heat to be supplied to or removed from the body. The fluid, for example, must be heated or cooled and then maintained at a predetermined temperature.
- In order to heat or cool the fluid in a temperature control device, energy is required that is provided as a general rule by the local power network. Thus, a conventional temperature control device comprises a power supply which allows the temperature control device to be connected to the local power network. Both the power supply as well as numerous individual electrical consuming components of the temperature control device must be adapted to the local power network. Since there are different local power networks in different regions of the world, the region of the world in which the temperature control device is ultimately supposed to be used and the specifications of the local power network according to which the power supply of the temperature control device and the temperature control device itself have to be configured must, with a considerable amount of effort, always be taken into consideration when constructing a temperature control device for hyper/hypothermia applications.
- Various embodiments of the invention simplify the construction of a temperature control device and provide a temperature control device for hyper/hypothermia systems that can be used in different regions of the world. This aim is achieved by 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 for heating or cooling a fluid including a power supply unit that supplies electrical consuming components of the fluid temperature control unit with power, and supplies the electrical consuming components with direct current.

FIG. 1 shows an embodiment of a temperature control device according to the invention. -
FIG. 2 shows a further embodiment of the temperature control device according to the invention. -
FIG. 1 shows a temperature control device 1 for use in a fluid-based hyperthermia or hypothermia system, according to embodiments of the invention. As shown inFIG. 1 , the control device 1 includes a connection unit 2 for connecting the device to alocal power network 3. In Germany, for example, the local power network is a general alternating current (AC) network of 220/380 V at 50 Hz. In Japan, for example, the local power network is an AC network of 100 V at, for example, 60 Hz. And in the United States, for example, the local power network is an AC network of 120 V at 60 Hz. These differences, and in particular the differences in frequency of the local power networks, lead to differences in the leakage currents which result from the change of the connected alternating current over time. For medical-technical systems in a surgical environment, the effects of electrical leakage currents, in the case for example of open heart surgeries, must remain minimal. To minimize these leakage currents, the electric lines in conventional temperature control devices must have certain insulations. This leads to increased material costs since, in particular, the insulation can age and must then be replaced if the guidelines with respect to the leakage currents are no longer met. - The temperature control device, according to the illustrative embodiments of the invention, is connected to the
power network 3 via the connection unit 2 and can draw the power required to control the temperature of the fluid from the power network. - The temperature control of the fluid is accomplished by means of a fluid temperature control unit 4 which includes the components required for heating or cooling the fluid. These normally include a
fluid container 5, a heater 6, acooler 7, asupply pump 8, a temperature sensor 9 and a temperature controller 10 (e.g., a microprocessor), each of which are shown inFIG. 1 merely in schematic form and as an example of the components of the fluid temperature control unit 4. In this embodiment, thesupply pump 8 works, for example, with a direct current motor and thecooler 7 includes a direct current compressor. Also shown by way of an example arepipelines 11, via which thepump 8 removes the fluid from thefluid container 5 and conveys it to the outside such that it can be used in the hyper/hypothermia system, or via which the fluid is conveyed out of the hyper/hypothermia system back into thefluid container 5. The pump can also be provided in the hyper/hypothermia system such that it can be omitted from the fluid temperature control unit 4 of a temperature control device 1 as according to the invention. Depending on the hyper/hypothermia system in which the temperature control device 1 is used, other components, such as a stirrer for the fluid in thefluid container 5, may be added to (or omitted from) the fluid temperature control unit 4. According to various embodiments, each of the components shown inFIG. 1 may be of the type disclosed in DE 696 34 572 T2, which is hereby incorporated by reference in its entirety. - To supply power to the electrical consuming components, for example, the heater 6, the
cooler 7, thesupply pump 8 and thetemperature controller 10, of the fluid temperature control unit of a temperature control device 1, apower supply unit 12 is provided according to the invention, via which all of the electrical consuming components of the fluid temperature control unit 4 are electrically supplied with constant connected loads irrespective of the local power network. According to embodiments of the invention, direct current is supplied, for example, with a supply voltage of 48 V and a power of up to 3.5 kW. Accordingly, the electrical consuming components of the fluid temperature control unit 4 are supplied via the power supply unit and are, thus, not directly connected to thepower network 3. Thus, these components need not be designed for the local power network, but are instead all supplied with direct current by thepower supply unit 12. Different electrical consuming components can thereby be supplied with different voltages/powers which are provided by thepower supply unit 12 according to the invention. This is indicated inFIG. 1 by the connections between thepower supply unit 12 and the fluid temperature control unit 4, which are dashed at one end. Thepower supply unit 12 thereby performs adaptation to the local power network and conversion to a power supply with constant connected loads. - The power supply unit thus performs any and all necessary conversions to adapt the temperature control device to the conditions of a local or regional power network. The adaptation to the local power network of the region in which the device is to be used is achieved by an appropriate design of the power supply unit, which, on the side facing the connection unit, must be designed for connection to the local power network, but on the side facing the fluid temperature control unit, a uniform power supply with direct current is ensured irrespective of the local power network.
- The power supply unit may be any standard power supply (including, for example, switched-mode power supplies) that provides (as standard) one or more of the supply voltages required by the fluid temperature control unit, so that the temperature of the fluid can be controlled. In this way, the fluid temperature control unit is electrically separate from the local power network. As a result, an improved electrical decoupling of the fluid temperature control unit from the power network is achieved, which has a positive effect on use in hyper/hypothermia systems, since network feedback and leakage currents can be reduced. In view of the fact that medical-technical systems such as hyper/hypothermia systems are subject to particularly critical specifications, this decoupling of the fluid temperature control unit from the local power network that is achieved by the power supply unit is advantageous.
- Supplying the electrical consuming components of the fluid temperature control unit with direct current enables more precise control during operation, since a precise power control for each individual electrical consuming component can take place, for example, with the aid of inverters. This is true not only for the heater/cooler of the fluid temperature control unit, but also for the pumps which are generally electromotively driven. Overall, the improved controllability of the temperature control device of the invention leads to a reduction of noise in a hyper/hypothermia treatment scenario.
-
FIG. 2 shows further embodiments of a temperature control device 1 according to the invention. As shown inFIG. 2 , the control device 1 additionally includes abattery 15 for supplying the electrical consuming components of the fluid temperature control unit 4 with power. Thebattery 15 is connected to thepower supply unit 12 and is charged by this unit when the supply of power occurs via the power network. In this way, thebattery 15 can supply power to thepower supply unit 12 to ensure delivery of a fail-safe supply of direct current to the electrical consuming components even where the local power network is subject to fluctuations or failure. Thus, designing the temperature control device with direct current electrical consuming components makes it possible to ensure the continuous operation of the temperature control device in a surgical environment.
