Portable sensor device and patient monitor
First Claim
1. A system for monitoring a patient comprising:
- a portable sensor device and a separate patient monitor that is removably connected to the portable sensor device, the portable sensor device comprising the following;
an electronic pressure sensor configured to measure a physiological pressure at a measurement site of the body of the patient;
a measurement site interface configured to connect the electronic pressure sensor to a measurement site connector, wherein said measurement site connector is configured to establish a measurement connection between the electronic pressure sensor and the measurement site;
a patient monitor interface configured to connect the electronic pressure sensor to a patient monitor connector, wherein said patient monitor interface is configured to establish an analog signal connection between the electronic pressure sensor and the patient monitor for transmitting an analog sensor signal;
an optical and/or acoustical output device that is controllable directly by a data signal from the patient monitor;
an electronic identification device configured to make an identification signal available to the patient monitor, wherein the identification signal identifies a property of the analog sensor signal transmitted by the analog signal connection; and
a sensor housing configured to accommodate the electronic pressure sensor, the measurement site interface, the at least one electronic additional component, the electronic identification device, and the patient monitor interface, said sensor housing being separate from the patient monitor;
wherein the patient monitor interface further comprises an input channel for receiving the data signal from the patient monitor,wherein the patient monitor interface further comprises a separate identification channel for output of the identification signal to the patient monitor, andwherein the patient monitor is configured to evaluate the analog sensor signal and display a physiological parameter determined from the analog sensor signal on a display of the patient monitor.

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.
