    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 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.

    Abstract: A system for measuring blood pressure of a wearer of an inflatable cuff and a method thereof. The system includes a piston, a bar lever located to restrict at least some movement of the piston, a motor coupled to an actuator that is coupled to the bar lever, and a processor in communication with the motor. The processor is configured to receive pressure data associated with the inflatable cuff and is configured to, based on a determination that the pressure data satisfies a threshold, actuate the motor to move the bar lever in a first or second direction. Movement of the bar lever in the first direction causes the piston to move in the first direction, thereby increasing the flow rate of gas through a gas pathway. Movement of the bar lever in the second direction causes a decrease in the flow rate of the gas through the gas pathway.

    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: 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 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.
