ABSTRACT:
A two-pointer blood pressure indicator gauge with pointer blocking solenoids for the indication of the systolic and diastolic pressures, the gauge having a blocking member or a brake disc directly attached to each of the two pointer shafts, and in which the armature of each solenoid, or a solenoid-actuated brake lever, cooperates with the associated brake member or brake disc, respectively, thereby blocking the spring-driven return motion of the pointers. The pointer for the higher pressure, being dragged by the other pointer during pressure buildup, against a separate spring, is blocked first, allowing the pointer for the lower pressure to continue its return movement until it, too, is blocked.
