Device for processing signals for medical sensors
First Claim
1. A device for processing signals of medical sensors (6) for display or analysis in a data monitor (1) that is designed for the analysis of signals from full-bridge or half-bridge circuits, comprising:
- a measuring circuit (11) for the detection, for scaling or correction of the sensor signals, and a bridge simulating circuit (12) comprising electrically controllable resistors, said resistors being connected to said data monitor to simulate either a scaled or corrected bridge circuit or both for the data monitor.

Abstract
The invention relates to a device for processing the signals of medical sensors for display or interpretation, respectively, in data monitors. The sensor signals are initially scaled or corrected, respectively, by means of an active circuit and are stored if and when necessary. The signals so corrected are then signalled to the data monitor by means of a bridge simulator or supplied to a correction circuit that corrects the signals of the sensor as such by feeding additional voltages or currents, respectively, or also by connecting further impedance elements.
