Signal transmitter and control circuit for a physiological variable
First Claim
1. A signal transmitter comprising a device for processing, using, and/or providing signals which are generated from measurement values of a physiological variable, wherein a sequence control approach is implemented in such a way that the measurement values are acquired from the detection of electromagnetic waves of various wavelengths, which have previously passed through a medium to be examined, especially tissue and/or vessels of a living or dead organism, and/or have been reflected by this medium;
- wherein at least for a certain percentage of the overall signal quantity, at least two measurement values are used for each generated signal, these values being so close together in time that they form a common signal; and
wherein the signals are intended to be transmitted to a signal receiver, which can be used to support the therapy and/or treatment of an organism.

Abstract
For detecting and processing a physiological variable, a signal transmitter has devices for processing, using, and/or providing signals, which are generated from measurement values of the physiological variable. In accordance with a sequence control approach, the measurement values are acquired from the detection of electromagnetic waves of different wavelengths. Before the signals are detected, the electromagnetic waves pass through the medium to be examined or are reflected by this medium. For at least a certain percentage of the overall signal quantity, at least two measurement values detected close together in time are used for each generated signal. The signal transmitter is suitable for use in a control circuit, which is designed with an actuator to influence the physiological variable detected instrumentally by the signal transmitter.

- wherein
- 20. A control circuit comprising a signal transmitter, which, with a signal receiving system, detects at least one physiological variable of a human being or animal and, with a signal evaluation unit, converts it into processed signals and transmits these signals to a signal receiver, where the transmitted processed signal is used in the signal receiver to influence at least one physiological parameter of the human being or animal with a direct or indirect effect on the physiological variable measured by the signal transmitter.
