Abstract: A blood pressure measurement system is provided that includes an inflatable cuff, a valve assembly and chamber assembly. The chamber assembly can house a gas canister for providing gas to the inflatable cuff. The valve assembly can include a valve having a high pressure cavity, a low pressure cavity, and a channel providing a gas pathway between the high pressure cavity and the low pressure cavity. The valve assembly can further include a channel cover and spring in the high pressure cavity. The spring can exert a force on the channel cover to create a seal between the high pressure cavity and the channel. The valve assembly can further include a rod extending through the channel and exerting a force on the channel cover to create a gas pathway between the high pressure cavity and the channel.

Abstract: A tissue profile wellness monitor measures a physiological parameter, generates a tissue profile, defines limits and indicates when the tissue profile exceeds the defined limits. The physiological parameter is responsive to multiple wavelengths of optical radiation after attenuation by constituents of pulsatile blood flowing within a tissue site. The tissue profile is responsive to the physiological parameter. The limits are defined for at least a portion of the tissue profile.

Abstract: An active-pulse blood analysis system has an optical sensor that illuminates a tissue site with multiple wavelengths of optical radiation and outputs sensor signals responsive to the optical radiation after attenuation by pulsatile blood flow within the tissue site. A monitor communicates with the sensor signals and is responsive to arterial pulses within a first bandwidth and active pulses within a second bandwidth so as to generate arterial pulse ratios and active pulse ratios according to the wavelengths. An arterial calibration curve relates the arterial pulse ratios to a first arterial oxygen saturation value and an active pulse calibration curve relates the active pulse ratios to a second arterial oxygen saturation value. Decision logic outputs one of the first and second arterial oxygen saturation values based upon perfusion and signal quality.

Abstract: A method and an apparatus for separating a composite signal into a plurality of signals is described. A signal processor receives a composite signal and separates a composite signal into separate output signals. Feedback from one or more of the output signals is provided to a configuration module that configures the signal processor to improve a quality of the output signals. In one embodiment, calibration data from multiple calibration data sets is used to configure the demodulation of the composite signal into separate output signals.

Abstract: A monitoring device for measuring one or more physiological parameters of a medical patient can include a finger clip sensor connected to a monitor. A placement indicator helps the patient to properly position the sensor. The monitor can display a message alerting the patient to reposition the sensor. The device can delay measurement until the sensor is properly positioned.

Abstract: A robust alarm system has an alarm controller adapted to input an alarm trigger and to generate at least one alarm drive signal in response. Alarm subsystems input the alarm drive signal and activate one or more of multiple alarms accordingly. A subsystem function signal provides feedback to the alarm controller as to alarm subsystem integrity. A malfunction indicator is output from the alarm controller in response to a failure within the alarm subsystems.

Abstract: A magnetic connector has a receptacle and a plug. The receptacle has an electromagnet comprising an inner core, an outer core, a coil disposed around the inner core and an air gap defined by the edges of the inner and outer cores. The plug has a plug core and an anchor defined by the plug core edge. The anchor is configured to insert into the air gap as a receptacle socket electrically connects with plug pins. The coil is energized and de-energized so as to assist in the insertion or removal of the anchor from within the air gap and the corresponding connection and disconnection of the socket and pins.

Abstract: A patient monitoring system includes an inflatable cuff, a gas reservoir containing a compressed gas, and a sensor. When the inflatable cuff is coupled to a wearer, the gas reservoir supplies gas to the inflatable cuff to inflate the inflatable cuff via gas pathways. As the inflatable cuff inflates, a patient monitor can receive blood pressure data from the sensor and use the blood pressure data to determine the blood pressure of the wearer. The patient monitor can also receive blood pressure data during deflation of the inflatable cuff to determine the blood pressure of the wearer.
