    Abstract: A magnetic-flap optical sensor has an emitter activated so as to transmit light into a fingertip inserted between an emitter pad and a detector pad. The sensor has a detector responsive to the transmitted light after attenuation by pulsatile blood flow within fingertip so as to generate a detector signal. Flaps extend from the emitter pad and along the sides of a detector shell housing the detector pad. Flap magnets are disposed on the flap ends and shell magnets are disposed on the detector shell sides. A spring urges the emitter shell and detector shell together, so as to squeeze the fingertip between its fingernail and its finger pad. The flap magnets have opposite north and south orientations from the shell magnets, urging the flaps to the detector shell sides and squeezing the fingertip sides. These spring and magnet squeezing forces occlude the fingertip blood flow and accentuate a detector signal responsive to an active pulsing of the fingertip.

    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: 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: 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.
