PATIENT MONITOR SENSOR TYPE AUTO CONFIGURATION

摘要

A method and system that allows various sensor types to be connected to common input ports of a patient monitor. The system includes a data acquisition module that identifies the type of sensor connected to each one of a plurality of input ports. Once the sensor type has been identified, the data acquisition module configures amplification circuits and input circuits such that the output signal from the sensor is properly received and amplified within the patient monitor. The properly amplified output signal from the sensor, along with a sensor identifier, is supplied to a controller of the patient monitor. In this manner, the patient monitor can identify the type of sensor connected to each input port and properly display the conditioned output signal from the sensor.

1. A data acquisition module for use with a patient monitor that receives and monitors physiological data obtained from one or more sensors connected to a patient, comprising:
at least one multi-mode input port included in the module for communication with one of the sensors when the sensor is connected to the input port; an interface circuit coupled to the input port, wherein the interface circuit is operable to selectively apply a default signal to the sensor connected to the input port; and a processor positioned to receive an output signal from the sensor, wherein the processor determines the type of sensor connected to the input port based upon the output signal generated in response to the default signal.
