Abstract

In a method for acquiring measurement data which are generated by a physiological sensor as a function of physiological parameters of a living being, in which the data generated by the physiological sensor are supplied to an external evaluation unit, which stores these data in a memory, in order to simplify the storing of data when using various sensors, it is proposed that its own memory is associated with each physiological sensor and data originating from the physiological sensor are exclusively stored in the memory associated with the physiological sensor. Moreover, a device for carrying out this method is given.

Claims

1. Method for acquiring measurement data which are generated by a physiological sensor as a function of physiological parameters of a living being, in which the data generated by the physiological sensor are supplied to an external evaluation unit, which stores these data in a memory, wherein each physiological sensor is associated with its own memory and data originating from the physiological sensor are exclusively stored in the memory associated with the physiological sensor.

2. Method according to claim 1, wherein to check the association of a memory with a physiological sensor, coding data, which are supplied to the evaluation unit by the physiological sensor, and coding data, which are in each case stored in each memory, are compared with one another and the measurement data supplied by the physiological sensor are only stored in a memory if the coding data of the physiological sensor and the memory match one another.

3. Method according to claim 2, wherein the coding data are stored in the memory in a non-variable manner.

4. Method according to claim 2, wherein calibration data of the associated physiological sensor are stored in the memories and these data are taken into account when evaluating the measurement data.

5. Method according to claim 1, wherein the various memories are configured as mobile assemblies and to acquire the measurement data of a physiological sensor, the memory associated with the physiological sensor is connected in each case to the evaluation unit.

6. Method according to claim 5, wherein a flash card which can be inserted in the evaluation unit is used as the memory.

7. Method according to claim 1, wherein when acquiring measurement data of the physiological sensor, measurement data are additionally generated by means of an external sensor, which data correspond to environmental parameters, and these measurement data are stored together with the measurement data of the physiological sensor in the memory associated with the physiological sensor.

8. Method according to claim 1, wherein the measurement data supplied by a physiological sensor to the evaluation unit are only stored in the associated memory if these measurement data satisfy certain plausibility criteria.

9. Method according to claim 8, wherein comparison data for checking the plausibility criteria are stored in the memories associated with the physiological sensors.

10. Method according to claim 1, wherein an intracranial pressure sensor, which supplies measurement data corresponding to the internal pressure of the brain, is used as the physiological sensor.

11. Device for acquiring measurement data, which are generated by a physiological sensor as a function of physiological parameters of a living being, comprising an evaluation unit, which is connected to the physiological sensor by means of a data transmission path, and comprising a memory device, in which the evaluation unit stores the measurement data supplied by the physiological sensor, wherein there is associated with each physiological sensor its own memory, in which the evaluation unit exclusively stores measurement data originating from the physiological sensor.

12. Device according to claim 11, wherein the evaluation unit is configured in such a way that, to check the association of a memory with a physiological sensor, it compares coding data, which are supplied by the physiological sensor to the evaluation unit, and coding data, which are stored in each case in each memory, with one another, and only stores the memory data supplied by the physiological sensor in a memory if the coding data of the physiological sensor and the memory match one another.

13. Device according to claim 12, wherein each memory has a non-variable memory region and a variable memory region and in that the coding data of the memory are stored in the non-variable memory region.
