Medical device with a radio frequency detection device

1. A medical device comprising:

a housing;

a radio frequency detection device comprising a transmitter and an at least partly electrically conductive shield, which encloses said transmitter such that a field generated by said transmitter is effectively shielded towards the outside; and

an antenna functionally connected to said radio frequency detection device for detecting a radio frequency identification element, said antenna being arranged within or on said housing and outside of said shield.

2. A medical device in accordance with claim 1 , wherein said antenna is arranged at least partly or completely directly at the inner surface of said housing.

3. A medical device in accordance with claim 1 , wherein said antenna is connected to said housing at least in some sections.

4. A medical device in accordance with claim 1 , wherein said antenna is formed by at least one electrically conductive loop.

5. A medical device in accordance with claim 1 , wherein said antenna is formed by an electrically conductive layer.

6. A medical device in accordance with claim 5 , wherein said antenna electrically conductive layer is applied to the inner surface of said housing by vapor deposition or electrolytically.

7. A medical device in accordance with claim 1 , wherein said antenna is formed by a longitudinally extending strip with at least one flat side.

8. A medical device in accordance with claim 1 , wherein said antenna has a loop shape with at least one angular longitudinal section.

9. A medical device in accordance with claim 1 , wherein said antenna has a loop shape with at least one roundly extending longitudinal section.

10. A medical device in accordance with claim 4 , wherein a shape along said loop has at least one rotatory degree of freedom and/or at least one translatory degree of freedom.

11. A medical device in accordance with claim 1 , wherein said antenna is connected to a compensation member, which is arranged outside said shield.

12. A medical device in accordance with claim 1 , wherein said antenna is connected to said transmitter by a shielded connection line.

13. A medical system comprising:

a medical device with a housing, a radio frequency detection device comprising a transmitter and an at least partly electrically conductive shield, which encloses said transmitter such that a field generated by said transmitter is effectively shielded towards the outside and an antenna functionally connected to said radio frequency detection device;

a medical part with a radio frequency identification element, said medical part being connected to said medical device for operation therewith, said antenna being arranged within or on said housing and outside of said shield for detecting said radio frequency identification element.

14. A medical device in accordance with claim 13 , wherein said antenna is arranged at least partly or completely directly at the inner surface of said housing.

15. A medical system in accordance with claim 14 , wherein said antenna is formed by at least one electrically conductive loop.

16. A medical system in accordance with claim 14 , wherein said antenna is formed by an electrically conductive layer formed on a substrate connected to said housing or forming a part of said housing.

17. A medical system in accordance with claim 16 , wherein said antenna electrically conductive layer is applied to the inner surface of said housing by vapor deposition or electrolytically.

18. A medical system in accordance with claim 15 , wherein a shape along said loop has at least one rotatory degree of freedom and/or at least one translatory degree of freedom.

19. A medical system in accordance with claim 14 , wherein said antenna is connected to a compensation member, which is arranged outside said shield.

20. A medical system in accordance with claim 14 , wherein said antenna is connected to said transmitter by a shielded connection line.
