A low-profile blood pressure measurement system and methods of use are disclosed. The system includes an expandable member or structure that has a multi-compartment structure and/or is mounted on a rigid surface or structure. The system is incorporated into a portable multi-function device, or is configured to communicate with a portable multi-function device.

Embodiments for protecting low-pressure blood pressure sensors in high-pressure fluid flow applications by equalizing pressure on both sides of a pressure sensor's diaphragm during high pressure are disclosed. A sensor protection device may include a pressure sensor assembly, a housing, and a plunger assembly. During low pressure, fluid in the primary flow path can flow through the housing, transferring its pressure to a first side of the diaphragm; the plunger assembly can prevent fluid flow into a secondary flow path in the housing, transferring atmospheric pressure to a second side of the diaphragm. During high pressure, fluid can still flow through the primary flow path, and the plunger assembly may now allow fluid flow into the secondary flow path, transferring pressure from the same fluid to the second side of the diaphragm to equal pressure across the diaphragm. The plunger assembly may automatically transition between low- and high-pressure configurations.

A charging station for providing power to a physiological monitoring device can include a charging bay and a tray. The charging bay can include a charging port configured to receive power from a power source. The tray can be positioned within and movably mounted relative to the charging bay. The tray can be further configured to secure the physiological monitoring device and move between a first position and a second position. In the first position, the tray can be spaced away from the charging port, and, in the second position, the tray can be positioned proximate the charging port, thereby allowing the physiological monitoring device to electrically connect to the charging port.

A sphygmomanometer includes a frame that spatially demarcates a region in which a display screen is displayed. On the display screen, a scale indication for making a value of pressure readable is displayed along one direction. On the display screen, a mark that represents a pressure of a cuff by a position of the mark with respect to the scale indication is displayed. When the pressure changes, a display control unit performs control to slide the scale indication with respect to the frame along the one direction at a slide speed corresponding to a predetermined pressure change rate or a pressure change rate obtained by actual measurement in a pressurizing process or a depressurizing process of the cuff so that the mark falls within the frame.

A blood pressure measuring device includes a holder configured to be mounted on a wrist of a living body and come into contact with a portion of the wrist at least between a dorsal side and a palmar side; a sensing cuff provided on a side of the holder nearer to the living body and arranged in a region of the wrist where arteries exist; and a cuff provided on a side of the holder nearer to the living body and arranged on the dorsal side of the wrist.

A sphygmomanometer according to the present invention includes a pump that supplies a fluid to a blood pressure measurement cuff, a pressure sensor that detects a pressure of the cuff, a first valve for regular measurement, and a second valve for emergency exhaust. A blood pressure measurement unit measures a blood pressure of a measurement target site by controlling operations of the pump and the first and second valves on the basis of the pressure of the cuff. The abnormality determination unit supplies the fluid to the cuff by the pump in a state where a closing instruction is given to the first valve and an opening instruction is given to the second valve, and determines whether or not there is an abnormality in an emergency exhaust function according to a degree of increase in the pressure of the cuff.
