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 (R2) which simulates the influence of a selectively attachable first monitoring device (1) on a measuring of the electric quantity, wherein the trimming element (R2) is electrically effective depending on a connector structure of a corresponding further connector (B, C) to be coupled with the first connector (A).

Description

technical field [0001] [0001] The present invention relates to disposable sensor devices for patient monitoring, such as arterial blood pressure sensor devices, pulse wave cardiac output devices, and the like. The invention further relates to a monitoring system for such a disposable sensor device. Background technique [0002] [0002] In patient monitoring, there are situations where there is a need for multiple monitoring devices dealing with the same parameters. For example, there may be a need for separate signals to be received by a parallel bedside monitor and portable device, both of which should be able to read the parameter of interest. Hitherto, separate sensor devices have been used for each monitoring device, such as bedside monitoring devices and portable measurement devices. Multiple sensor devices may be closely spaced to detect the same or at least approximate results, eg as described in US 2006 / 0009699. [0003] [0003] Typically, sensor devices require som...
