Abstract

An oximeter sensor probe system includes a sensor probe unit that is connected by a wire to a sensor probe electronic module. The sensor probe electronic module connects wirelessly to a medical device console, which can be a phone, tablet, or other mobile device. And the mobile device can connect to a network or the Internet (e.g., the Cloud). Alternatively, the sensor probe electronic module can directly to the network or the Internet directly without a medical device console. The medical device console can execute an application and show on its display oxygen saturation and related measurements obtained through the sensor probe unit.
