Abstract

A measuring system for measurement of patient data inside a patient'"'"'s body includes a flexible foil for implantation into the patient'"'"'s body. At least one sensor is arranged on the flexible foil. A first telemetry unit is also arranged on the flexible foil. The telemetry unit is provided for receiving an inductive power transmission and for transmitting data. Strip conductors electrically connect the at least one sensor element to the telemetry unit. Preferably, the at least one sensor includes a pressure sensor for sensing the patient'"'"'s brain or cranial pressure. The at least one sensor may optionally include a temperature sensor the patient'"'"'s brain temperature. A second telemetry unit is located outside the patient'"'"'s body for receiving the data from the first telemetry unit and for transmitting the inductive power transmission to the first telemetry unit.

Claims

1. A measuring system for measurement of patient data inside a patient'"'"'s body, said system comprising:

a flexible foil for implantation into the patient'"'"'s body;

at least one sensor arranged on said flexible foil;

a first telemetry unit arranged on said flexible foil, said telemetry unit for receiving an inductive power transmission and for transmitting data; and

strip conductors electrically connecting said at least one sensor element to said telemetry unit.

2. The system according to claim 1, wherein said at least one sensor includes a pressure sensor.

3. The system according to claim 2, wherein said pressure sensor is for sensing a brain pressure.

4. The system according to claim 2, wherein said at least one sensor includes a temperature sensor.

5. The system according to claim 4, wherein said temperature sensor is for sensing a brain temperature.

6. The system according to claim 1, further comprising:

a second telemetry unit for positioning outside the patient'"'"'s body and for having communications with said first telemetry unit.

7. The system according to claim 6, wherein said communications include receiving said data from said first telemetry unit.

8. The system according to claim 6, wherein said communications include transmitting said inductive power transmission to said first telemetry unit.

9. The system according to claim 8, wherein said communications include receiving said data from said first telemetry unit.

10. The system according to claim 6, wherein said at least one sensor includes a pressure sensor.

11. The system according to claim 10, wherein said pressure sensor is for sensing a brain pressure.

12. The system according to claim 10, wherein said at least one sensor includes a temperature sensor.

13. The system according to claim 12, wherein said temperature sensor is for sensing a brain temperature.

14. The system according to claim 1, wherein said at least one sensor is located on one side of said flexible foil, and said first telemetry unit is located on an opposite side of said flexible foil.

15. The system according to claim 1, wherein said strip conductors are arranged on said flexible foil.
