ABSTRACT:
An automatic blood pressure measuring device includes a flexible inflation system which quickly and accurately inflates neonatal, pediatric and adult cuffs without significant pressure overshoot. The device uses an electric pump having two intake orifices. A restricted orifice provides air to the pump for all cuff sizes. An unrestricted orifice, which may be opened or closed by actuating a valve, provides air to the pump only when an adult or pediatric cuff is being used. In addition, the pump is controlled by a motor controller which provides dynamic breaking to stop the pump quickly when the threshold pressure has been reached. An overpressure mechanism, separate from the pressure sensor that controls the pump, removes operational power from the pump when a predetermined cuff pressure level, greater than the threshold pressure, has been reached.
