Portable sensor device and patient monitor
First Claim
1. A portable sensor device that comprises the following:
- an electronic sensor component for measuring a physiological variable at a measurement site of the body of a patient,a measurement site interface for connecting the electronic sensor component to measurement site connection means for establishing a measurement connection between the electronic sensor component and the measurement site,a patient monitor interface for connecting the electronic sensor component to patient monitor connection means for establishing a signal connection between the electronic sensor component and the patient monitor, anda sensor housing for accommodating the electronic sensor component, the measurement site interface, and the patient monitor interface,wherein the patient monitor interface has an input channel for receiving a data signal from the patient monitor, andthe portable sensor device has at least one electronic additional component that can be influenced by the data signal.

Abstract
The portable sensor device is connected with the arterial pressure measurement catheter by way of a pressure hose. The electronic pressure sensor is accommodated in the sensor housing. The analog sensor signal is output to the patient monitor by way of a cable. Aside from the channel for the analog sensor signal, additional channels are provided for communication between sensor device and patient monitor. A bidirectional channel serves for writing to and querying the memory module, in which patient data, such as age, gender, height/weight, etc., can be stored. The three-way cock possesses the settings “M” (measurement operation) and “0” (calibration measurement), in which the contactor is brought into connection with the contact. The switching contact is transmitted to the patient monitor, which thereby automatically recognizes zeroing of the sensor.
