Disposable Sensor Device and Monitoring System

Abstract

The invention relates to a disposable sensor device ( 51 ) for patient monitoring comprising a sensor ( 52 ) for providing an electric quantity based on a quantity to be detected, a first signal terminal ( 54 ) for providing a tap for the electric quantity, a first supply terminal ( 53 ) for supplying the sensor with an electrical supply quantity, a first connector for accommodating the first signal terminal ( 54 ) and the first supply terminal ( 53 ), a second signal terminal ( 56 ) for providing a further tap for the electric quantity, and a second connector for accommodating at least the second signal terminal ( 56 ). The invention further relates to a disposable sensor device for patient monitoring comprising a sensor ( 7 ) for providing an electric quantity based on a quantity to be detected; a first signal terminal ( 22 ) for providing a tap for the electric quantity; a first connector (A) for accommodating the first signal terminal, wherein the first connector (A) is provided with a trimming element (R 2 ) which simulates the influence of a selectively attachable first monitoring device ( 1 ) on a measuring of the electric quantity, wherein the trimming element (R 2 ) is electrically effective depending on a connector structure of a corresponding further connector (B, C) to be coupled with the first connector (A).
