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 reflection-detector sensor position indicator comprises emitters that transmit light having a plurality of wavelengths. A detector outputs a sensor signal. At least one reflection detector outputs at least one sensor position signal. An attachment assembly attaches the emitters, the detector and the reflection detector onto a tissue site. A sensor-on condition indicates that the attachment assembly has positioned the emitters generally centered over a fingernail, the detector on a fingertip opposite the fingernail and the reflection detector over the fingernail. The sensor signal, in the sensor-on condition, is at least substantially responsive to the emitter transmitted light after attenuation by pulsatile blood flow perfused within a fingernail bed underneath the fingernail. The sensor position signal, in the sensor-on condition, is at least substantially responsive to the emitter transmitted light after reflection off of the fingernail.

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 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 plug core disposed around a plug contact set and a receptacle core disposed around a receptacle contact set. The plug core defines a generally elongated circular plug core edge. The receptacle core defines a generally elongated concentric-circular receptacle core edge. The receptacle core edge defines an air gap and the plug core defines an anchor configured to insert into the air gap. A coil is disposed around the receptacle core, and the coil, the plug core and the air gap define a magnetic circuit. The coil is electrically energized so as to form a magnetic field within an air gap, lock the anchor within the air gap and lock the plug contact set to the receptacle contact set accordingly.

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.
