Abstract

A medical device (10) for treating a patient, with a device body (12), at which at least one functional unit (14) to be operated manually by a treating person is arranged. The device (10) has a disinfection unit (20), which is provided separately from the functional unit and comprises a housing (22) arranged at the device body (12) with a disinfection chamber (26) for receiving at least one hand of the treating person, a plasma generator (28) arranged in the disinfection chamber for generating an atmospheric plasma (P) disinfecting the hand of the treating person and a control unit (50) for actuating the plasma generator (28).

Claims

1. A medical device for treating a patient, the medical device comprising:

a device body;

a functional unit to be operated by a treating person manually, said functional unit being arranged at said device body; and

a disinfection unit provided separately from said functional unit, said disinfection unit comprising a housing arranged at said device body, a disinfection chamber for receiving at least one hand of the treating person, a plasma generator arranged in said disinfection chamber for generating an atmospheric plasma disinfecting the hand of the treating person and a control unit for actuating said plasma generator.

2. A medical device in accordance with claim 1, wherein said disinfection unit has a sensor for detecting the hand of the treating person in said disinfection chamber.

3. A medical device in accordance with claim 2, wherein said control unit actuates said plasma generator as a function of a detection signal generated by said sensor.

4. A medical device in accordance with claim 1, wherein said disinfection unit has an initializing means for generating an initialization signal and said control unit puts said plasma generator into operation upon receiving said initialization signal and switches it off after an end of a predetermined operating time.

5. A medical device in accordance with claim 4, wherein:

said initialization means is formed by a sensor for detecting the hand of the treating person in the disinfection chamber;

said control unit actuates said plasma generator as a function of a detection signal generated by said sensor; and

said initialization signal is formed by said detection signal.

6. A medical device in accordance with claim 4, wherein said initialization means is formed by two manually actuatable control elements which are separated from each other in space and are to be actuated simultaneously to generate said initialization signal.

7. A medical device in accordance with claim 2, wherein said sensor is formed by a photoelectric cell arranged in said disinfection chamber.

8. A medical device in accordance with claim 1, wherein:

said disinfection unit has a light source arranged in said disinfection chamber; and

said control unit puts said light source into operation for a predetermined disinfection time, during which the atmospheric plasma exerts disinfecting action.

9. A medical device in accordance with claim 1, wherein said disinfection unit has an exhaust device for exhausting the atmospheric plasma generated in said disinfection chamber.

10. A medical device in accordance with claim 9, wherein said disinfection unit has a filter, which is arranged between said exhaust device and a gas outlet.

11. A medical device in accordance with claim 1, wherein said control unit makes a log of data on the operating state of said disinfection unit.

12. A medical device in accordance with claim 11, wherein said disinfection unit has an interface for outputting the logged data.

13. A medical device in accordance with claim 1, wherein said housing is a cuboid box, which has an opening to said disinfection chamber.

14. A medical device in accordance with claim 1, wherein said housing is designed as a drawer module.

15. A medical device in accordance with claim 1, wherein the medical device is part of one or more of an anesthesia device, a respirator, a patient monitor, a carrying system for receiving medical devices, a syringe pump and an infusion pump.

16. A medical device for treating a patient, the medical device comprising:

a device body;

a functional unit to be operated by a treating person manually, said functional unit being operatively connected to said device body; and

a disinfection unit provided separately from said functional unit, said disinfection unit comprising a housing operatively connected to said device body, a disinfection chamber for, a plasma generator generating an atmospheric plasma in said disinfection chamber for disinfecting some part of the treating person and a control unit for actuating said plasma generator.

17. A medical device in accordance with claim 16, wherein:

said disinfection unit has a sensor for detecting the part of the treating person in said disinfection chamber; and

said control unit actuates said plasma generator as a function of a detection signal generated by said sensor.

18. A medical device in accordance with claim 16, wherein:

said disinfection unit has an initializing device generating an initialization signal;

said initialization device is formed by at least one of a sensor for detecting the part of the treating person in the disinfection chamber, to generate said initialization signal, and two manually actuatable control elements which are separated from each other in space, and are to be actuated simultaneously to generate said initialization signal; and

said control unit actuates said plasma generator as a function of said initialization signal.

19. A medical device in accordance with claim 16, wherein:

said disinfection unit has a light source arranged in said disinfection chamber; and

said control unit puts said light source into operation for a predetermined disinfection time, during which the atmospheric plasma exerts disinfecting action.

20. A medical device in accordance with claim 16, wherein said disinfection unit has an exhaust device for exhausting the atmospheric plasma generated in said disinfection chamber.
