Device and Method for Determining a Comparison Value of Biodata and for Recording Biodata
First Claim
1. A device for determining a reference value of biophysical data (body parameters) of an individual for determining an individual risk, said device consisting of at least one sensor for the noninvasive measurement of at least two signals, which are selected from the following group:
- CWF (continuous wave fluctuation), SpO2, heart rate, and PTT (pulse transit time), and an evaluation unit connected to the sensor, where the evaluation unit has at least one analyzer, which determines signal ranges that can be defined by signal analysis, wherein a comparator coordinates the signal ranges, taking additional parameters into account, such as existing biophysical data of the individual and/or static data sets, and that the result can be output as an index value.

Abstract
The method and the device are used for evaluating recorded measurement data. In particular, the use of the method and of the device makes it possible to detect the individual risk of a living being in respect of certain disease states and, if appropriate, to automatically evaluate correspondingly recognized risks in a device control. Measurement data in respect of heart-specific and/or circulation-specific parameters or respiration-specific parameters of a patient are preferably recorded and evaluated. The measurement data are determined over a defined period of time and the measurement data are evaluated taking into account the time information. A particularly effective implementation of the method can be based on pattern recognition in which individual patterns and/or sequence patterns are evaluated.
