Abstract

A device for the determination of sleep profiles is described. The device has an electrode unit, a signal recording unit and a signal processing/signal evaluating unit separated from the signal recording unit. The signals obtained from the electrode unit are stored on a storage unit adapted to be taken out from and to be replaced in the signal recording unit. The storage unit is supplied to the separated signal processing/signal evaluating unit and is read into the same there. If the signal processing/signal evaluating modalities are modified with this device no modification of the hardware is necessary but only the software of the signal processing/signal evaluating unit has to be modified.

Claims

1. A device for the determination of sleep profiles comprising

an electrode unit (1);

a signal recording unit (4);

a replaceable storage unit (13) adapted to be taken out from the signal recording unit (4); and

a signal processing/signal evaluating unit (15) separated from the signal recording unit (4) and into which the storage unit (13) can be read.

2. The device according to claim 1, characterized in that the storage unit (13) is a multimedia card.

3. The device according to claim 1 or 2, characterized in that the signal recording unit (4) includes a filter stage (5), an A/D converter stage (6), a microcontroller (7) and a current supply (9).

4. The device according to one of the preceding claims, characterized in that the signal recording unit (4) has an event key (8).

5. The device according to one of the preceding claims, characterized in that the signal processing/signal evaluating unit (15) is a personal computer.

6. The device according to one of the preceding claims, characterized in that the electrode unit (1) has at least three electrodes (2).

7. The device according to one of the preceding claims, characterized in that the electrode unit (1) has an electrode carrier (17).

8. The device according to one of the preceding claims, characterized in that a pre-amplifier (3) is integrated into the electrode unit (1).

9. The device according to one of the preceding claims, characterized in that the signal processing/signal evaluating unit (15) includes a reading unit (14), an interface or a drive for reading into the storage unit (13).

10. The device according to one of the preceding claims, characterized in that the signal recording unit (4) is controllable or pre-programmable by the signal processing/signal evaluating unit (15) through the storage unit (13).
