Dual-mode pulse oximeter
First Claim
1. A physiological measurement apparatus comprising:
- a sensor responsive to a physiological state;
a measurement processor means for calculating a physiological parameter based upon said physiological state;
a display means for presenting said physiological parameter to a person;
a packaging means for housing said measurement processor and said display and for providing a connection between said sensor and said measurement processor means;
an interface means for electrically connecting said packaging means to a multiparameter patient monitoring system (MPMS) in an integrated mode and for disconnecting said packaging means from said MPMS in a portable mode; and
a docking station means for plugging into a slot portion of said MPMS, said packaging means configured to attach to said docking station in said integrated mode.

Abstract
A pulse oximeter has an integrated mode in which it operates as a plug-in module for a multiparameter patient monitoring system (MPMS). The pulse oximeter also has a portable mode in which operates separately from the MPMS as a battery-powered handheld or standalone instrument. The pulse oximeter has a sensor port that receives a photo-plethysmographic signal as input to an internal processor. The pulse oximeter processes this sensor signal to derive oxygen saturation and pulse rate measurements. In the portable mode, this information is provided on its display, and stored in memory for trend capability. In the integrated mode, the pulse oximeter provides oxygen saturation and pulse rate measurements to the MPMS through a docking station to be displayed on a MPMS monitor. In the integrated mode, the portable pulse oximeter docks to the docking station, which in turn is inserted in one or more MPMS slots. The docking station can function as a simple electrical pass-through device between the docked portable pulse oximeter and the MPMS or it can provide a MPMS communications interface.

2. A physiological measurement system comprising:
-
a monitor capable of accepting one or more signals from a light sensitive detector capable of detecting light attenuated by body tissue of a patient, the monitor also being capable of determining one or more physiological parameters of the patient based on the one or more signals from the light sensitive detector; and
a docking station capable of communicating with the monitor and with a multiparameter measurement device (MPMS), wherein the docking station generates one or more output signals interpretable by the MPMS. - View Dependent Claims (3, 4, 5, 6, 7, 8, 9, 10, 11, 12)
