Abstract

A portable pressure detecting device is provided employing a fluid-filled bulb of a suitable size to fit within the mouth of a person to sense pressure generated within the mouth. In addition, a fluid-filled bulb of a suitable size to fit within the hand of the person serves to sense pressure generated by the hand. A transducer is alternatively connectable with each bulb for converting the pressure sensed by the connected bulb to an electrical signal representing the sensed pressure. A pressure comparator circuit is responsive to the electrical signal for comparing the sensed pressure to a selected predetermined pressure level for producing an output indicating the proportion of the sensed pressure relative to the predetermined pressure level. A peak pressure detection circuit is responsive to the electrical signal for detecting the peak pressure sensed by the bulb. An LCD display selectively displays the sensed moment-to-moment pressure, the peak pressure, or the selected predetermined pressure level. An LED display selectively displays the proportion of the sensed pressure relative to the predetermined pressure level.
