1. Apparatus for measuring blood pressure, comprising:

  • an inflatable cuff for affixing to a body in a position to obturate an artery;

    manually operable inflation means, connected to the inflatable cuff, for progressively inflating/deflating said cuff;

    pressure means coupled and responsive to the pressure in the inflatable cuff for measuring the pressure exerted in said cuff;

    pulse sensing means for sensing a pulse of the body;

    converting means, coupled to the pulse sensing means, for converting the pulse into an indication which is perceivable visually/audibly and means for coupling the pulse sensing means to the converting means; and

    a pressure sensitive microswitch coupled to the pressure developed by the inflation means and effective to connect an electrical current supply to the converting means only after the pressure rises above a predetermined value.
