Abstract

A medical system with a medical device and with a supply unit. The supply unit is designed to be separably connected to the medical device and to supply the medical device with electric energy without interruption. The medical system has an isolating transformer and a changeover device, wherein the changeover device is connected to the isolating transformer and to the medical device and is designed to connect the medical device or the supply unit to an electric supply network via the isolating transformer as desired.

Claims

1. A medical system comprising:

a medical device;

a supply unit separably connected to said medical device at a physical interface to supply said medical device with electric energy without interruption;

an isolating transformer; and

a changeover device, said changeover device being connected at least indirectly to said isolating transformer and to said medical device, said changeover device for connecting said medical device to an electric supply network via said isolating transformer and for connecting said supply unit to the electric supply network via said isolating transformer as desired.

2. A medical system in accordance with claim 1, wherein said isolating transformer is a part of a unit comprising said medical device.

3. A medical system in accordance with claim 1, wherein said medical device has a network input for connection to the supply network, and said changeover device connects said isolating transformer on an output side at least indirectly to said medical device or to said supply unit as desired.

4. A medical system in accordance with claim 1, wherein said supply unit has a power supply unit for supplying said medical device with power without interruption and a network input for connection to the supply network, and said changeover device is designed to connect said network input of said supply unit at least indirectly to said isolating transformer or to said power supply unit.

5. A medical system in accordance with claim 1, wherein said changeover device has a first changeover switch and a second changeover switch, wherein said first changeover switch is connected to said medical device and said second changeover switch is connected to said supply unit.

6. A medical system in accordance with claim 5, further comprising an interface wherein said first changeover switch and said second changeover switch are separably connected to one another by means of said interface, and a medical device interface side is connected to said first changeover switch for connection to said supply unit and a supply unit interface side is connected to said second changeover switch for connection to said medical device.

7. A medical system in accordance with claim 1, wherein said supply unit has an energy storage means for storing electric energy and detecting a line voltage of the electric supply network and to sending electric energy stored in said energy storage means depending on the detected line voltage.

8. A medical system in accordance with claim 1, wherein said isolating transformer has a primary winding and a secondary winding, wherein said primary winding is connected to the electric supply network and said secondary winding connected to said supply unit or said medical device.

9. A medical system comprising:

a medical device;

a supply unit separably connected to said medical device to supply said medical device with electric energy without interruption;

an isolating transformer; and

a changeover device, said changeover device being connected at least indirectly to said isolating transformer and to said medical device, said changeover device for connecting said medical device and said supply unit to an electric supply network via said isolating transformer as desired, wherein said changeover device has a detection device designed to detect when said medical device is connected to said supply unit and to activate said changeover device for changing over depending on a connection state.

10. A medical system comprising:

a medical device;

a supply unit separably connected to said medical device to supply said medical device with electric energy without interruption;

an isolating transformer; and

a changeover device, said changeover device being connected at least indirectly to said isolating transformer and to said medical device, said changeover device for connecting said medical device and said supply unit to an electric supply network via said isolating transformer as desired wherein said changeover device has a detection device for detecting a line voltage, said detection device detecting a presence of a line voltage and activating said changeover device for changing over depending on the detected line voltage.

11. A process for supplying a medical device with electric energy, the process comprising the steps of:

providing a medical device with a network input for connection to an electric supply network;

providing a supply unit with a network input for connection to the electric supply network, said supply unit being separably connected to said medical device by a physical interface to supply said medical device with electric energy without interruption;

providing an isolating transformer;

providing a changeover device, said changeover device being connected at least indirectly to said isolating transformer and to said medical device; and

using said changeover device for connecting said medical device to the electric supply network via said isolating transformer and for connecting said supply unit to the electric supply network via said isolating transformer depending on an electrical or additionally mechanical connection of said medical device to said supply unit to supply energy from at least one electric supply network in a galvanically separated manner.

12. A process in accordance with claim 11, wherein said isolating transformer is a part of a unit comprising said medical device.

13. A process in accordance with claim 11, said changeover device connects said isolating transformer on an output side at least indirectly to said medical device or to said supply unit as desired.
