Method for measuring the coagulation time of organic substances (and albuminoid
Abstract
Abstract A METHOD FOR MEASURING THE COAGULATION TIME OF ALBUMINOID SUBSTANCES AND LIQUIDS, SUCH AS BLOOD, CHARACTERIZED BY UTILIZING THE INTERCEPTING PROPERTY OF A LIGHT BEAM ON A PHOTELECTRIC CELL FROM LIQUID STATE BLOOD (WITH RESPECT TO A LIGHT BEAM WHICH IS TO PERIODICALLY PASS THROUGH IR), THE TEST-TUBE BEING AT A HORIZINTAL POSITION DURING THE FIRING OF SAID BEAM, AND AT A VERTICAL POSITION FOR THE REMAINING CYCLE PERIOD, WHICH WILL CONTINUE UNTIL, ON CLOT BEING ACHIEVED, THE BLOOD REMAINS ON THE BOTTOM OF THE TEST-TUBE AND THE LIGHT BEAM BY PASSING THERETHROUGH WILL CAUSE THE APPARATUS TO BE STOOPED AND PROVIDE A SIGNAL FOR THE EXACT TIME TAKEN FOR COAGULATION.
