ABSTRACT:
An expansible, pressure-sensitive, metallic element is screw fastened at one side thereof coaxially to a hose connection pipe fitting passing through and fixed to the casing of a sphygmomanometer and is coupled at its other side to a transmission mechanism to an indicator pointer, the metallic element being adjustably turnable and displaceable relative to the transmission mechanism by a tool inserted through the pipe fitting thereby to set the pointer at zero reading for zero gage pressure. Alternatively, an actuating member coupled to the transmission mechanism is screw fastened to one side of the metallic element, which is fixed on its other side to the pipe fitting, and the actuating member is adjustably turnable and displaceable relative to the transmission mechanism by a tool inserted through the pipe fitting and interior of the metallic element thereby to set the pointer at zero reading.
