Abstract

A foot switch (1, 26) for use with a medical device (16, 27, 28) comprises an interface (10) for a communications link between the foot switch (1, 26) and a control unit (12) of the device (16, 27, 28) and comprises at least one pedal (2, 3) for operating the foot switch (1, 26) using a foot. An operation sensor (17) captures an operation of the foot switch (1, 26) for switching a function of the medical device (16, 27, 28). The control unit (12) assigns the function to the pedal (2, 3) via the interface (10) and the assigned function is displayed on the foot switch (1, 26) by a multicolor LED (4, 5).

First claim

The invention claimed is:

1. A foot switch configured for use with a medical device, comprising:
an interface for a communications link between the foot switch and a control unit of the medical device,
at least one pedal configured to operate the foot switch using a foot,
an operation sensor, which is configured to capture an operation of the foot switch,
wherein the operation sensor generates a signal that is transmitted via the interface to the control unit of the medical device for the purposes of switching a function of the medical device,
a processor, in the foot switch, which is configured to receive signals from the control unit of the medical device, the signals configured to assign the function to be switched to the at least one pedal, via the interface, and
at least one LED on the foot switch configured to display the assigned function for the footswitch in a certain color of the at least one LED, wherein the LED is a multicolor LED which can generate light in a multiplicity of different colors for the purposes of displaying different assigned functions for the foot switch.

2. The foot switch as claimed in claim 1 , wherein the multicolor LED comprises at least two light-emitting diodes, which comprise a common anode or a common cathode.

3. The foot switch as claimed claim 1 , wherein the multicolor LED comprises at least two light-emitting diodes, which are arranged in a common LED housing.

4. The foot switch as claimed in claim 1 , wherein the multicolor LED can reproduce all colors of an RGB color space.

5. The foot switch as claimed in claim 1 , wherein the foot switch comprises a housing, on which the at least one pedal and the at least one multi-color LED are arranged.

6. The foot switch as claimed in claim 5 , wherein the housing additionally comprises an operation switch, which is illuminated by a further light-emitting diode or which is surrounded by an edge illuminated by a further light-emitting diode.

7. The foot switch as claimed in claim 1 , wherein the foot switch comprises at least two pedals and at least two multicolor LEDs and different functions can be assigned to the pedals by the control unit of the medical device and the assigned functions are each displayed by one of the multicolor LEDs.

8. The foot switch as claimed in claim 1 , wherein each multicolor LED is covered by a transparent viewing window, through which a user can see the light color generated by the multicolor LED.

9. The foot switch as claimed in claim 8 , wherein the viewing window is arranged in a plane of the housing.

10. The foot switch as claimed in claim 1 , wherein the foot switch and the medical device are linked via a medical data transmission system and communicate via the latter.

11. A medical system comprising at least two devices and at least one foot switch as claimed in claim 1 , wherein the devices and the at least one foot switch are linked via a medical data transmission system and communicate via the latter.

12. A foot switch configured to control a medical device comprising:
an interface for a communications link between the foot switch and a control unit of the medical device,
at least one pedal configured to operate the foot switch when manipulated by a foot,
a processor, in the foot switch, which is configured to receive signals, via the interface, from the control unit of the medical device, the signals configured to assign a function of the medical device to be switched by the at least one pedal to the at least one pedal,
an operation sensor, which is configured to capture an operation of the foot switch when manipulated by the foot, wherein the operation sensor generates a signal that is transmitted, via the interface, to the control unit of the medical device to switch the function of the medical device, and
at least one LED on the foot switch configured to display the function assigned to the footswitch by processor in a certain color of the at least one LED, wherein the LED is a multicolor LED which can generate light in a multiplicity of different colors for the purposes of displaying assigned functions of the foot switch.

13. The foot switch as claimed in claim 12 , wherein the multicolor LED comprises at least two light-emitting diodes, which comprise a common anode or a common cathode.

14. The foot switch as claimed claim 12 , wherein the multicolor LED comprises at least two light-emitting diodes, which are arranged in a common LED housing.

15. The foot switch as claimed in claim 12 , wherein the multicolor LED can reproduce all colors of an RGB color space.

16. The foot switch as claimed in claim 12 wherein the foot switch comprises a housing, on which the at least one pedal and the at least one multi-color LED are arranged.

17. The foot switch as claimed in claim 16 , wherein the housing additionally comprises an operation switch, which is illuminated by a further light-emitting diode or which is surrounded by an edge illuminated by a further light-emitting diode.

18. The foot switch as claimed in claim 12 , wherein the foot switch comprises at least two pedals and at least two multicolor LEDs and different functions can be assigned to the pedals by the control unit of the medical device and the assigned functions are each displayed by one of the multicolor LEDs.

19. The foot switch as claimed in claim 12 , wherein each multicolor LED is covered by a transparent viewing window, through which a user can see the light color generated by the multicolor LED.

20. The foot switch as claimed in claim 19 , wherein the viewing window is arranged in a plane of the housing.

21. A programmable foot switch configured to control a medical device with an assignable function comprising:
a communications interface between the foot switch and a control unit of the medical device,
at least one pedal configured to operate the foot switch when manipulated by a foot,
a processor, in the foot switch, configured to receive a signal or command, via the interface, from the control unit of the medical device, the signals configured to assign a function of the medical device to be switched by the at least one pedal to the at least one pedal,
an operation sensor configured to capture an operation of the foot switch when manipulated by the foot, wherein the operation sensor generates a control signal that is transmitted, via the interface, to the control unit of the medical device to switch the function of the medical device, and
at least one LED on the foot switch configured to display the function assigned to the footswitch in a certain color, wherein the LED is a multicolor LED which can generate light in a multiplicity of different colors for the purposes of displaying the function assigned to the foot switch.
