Abstract

A sensor system is used for measuring, transmitting, processing and displaying a brain parameter. The sensor system has at least one implantable brain parameter sensor with a wireless transmission unit for measuring the brain parameter. At least one receiving unit with an antenna is in wireless signal connection with the latter. At least one data read module is in signal connection with the antenna and a data processing and display device is in turn in signal connection with said data read module. The sensor system also has a head cap or a head hood, on which the receiving unit is fixed to predetermine a relative position relative to the transmitting unit. A sensor system is the result, the use of which remains comfortable for the patient even over a relatively long measuring period.

Claims

1. A senor system (1) for measuring, transmitting, processing and displaying a brain parameter

with at least one implantable brain parameter sensor with a wireless transmission unit (4) for measuring the brain parameter,

with at least one receiving unit (8) with an antenna (9), which is in wireless signal connection with the transmission unit (4),

with at least one data read module (18), which is in signal connection with the antenna (9) by means of a signal connection (17),

with at least one data processing and display device (20), which is in signal connection (19) with the data read module (18),

comprising a head cap or a head hood (14) configured to be worn on a patient'"'"'s head, outside of the patient'"'"'s scalp, on which the receiving unit (8) is fixed to predetermine a relative positioning relative to the transmission unit (4), and

wherein the head cap or the head hood (14) has a plurality of at least one of individual bands or individual tubes, which are configured as a grid network having a plurality of crossing points, wherein the receiving unit (8) can be fixed on at least one of the plurality of crossing points of the grid network.

2. A sensor system (1) according to claim 1, wherein the antenna (9) is part of a printed circuit.

3. A sensor system (1) according to claim 1, wherein the receiving unit (8) is fixed to head cap or the head hood (14) by a hook-and-loop connection (15).

4. A sensor system (1) according to claim 1, wherein the receiving unit (8) can be placed by means of a housing ring (11) on a patient'"'"'s head.

5. A sensor system (1) according to claim 1, comprising a flexible membrane (12), by means of which the receiving unit (8) can be placed on the patient'"'"'s head.

6. A sensor system (1) according to claim 5, wherein a layer (13) of variable shape is arranged between the flexible membrane (12) and the antenna (9).

7. A sensor system (1) according to claim 6, wherein the layer (13) is a gel layer.

8. A sensor system (1) according to claim 1, wherein the data read module (18) and the receiving unit (8) are configured as an integral modular unit and can be fixed to the head cap or the head hood (14).

9. A head cap or head hood (14) comprising the at least one receiving unit (8) of the sensor system (1) according to claim 1, the head cap or head hood formed of a flexible material.

10. A sensor system (1) according to claim 1, wherein the receiving unit (8) has fastening means to allow the receiving unit be fastened to crossing points of said grid network.
