Means for simulating the natural flow of blood

Abstract

Abstract MECHANICAL MEANS FOR SIMULATING THE NATURAL FLOW OF BLOOD, INCLUDING MOTOR MEANS HAVING AN ECCENTRICALLY LOCATED CAM ON ITS DRIVE SHAFT FOR PROVIDING MOTION TO A CRANK LEVER HAVING A MOVABLE PIVOT POINT. A VESSEL CONTAINING A BLOOD SAMPLE UNDER ANALYSIS IS RETAINED ON THE CRANK LEVER TO RECEIVE THE MOTION ESTABLISHED BY THE MECHANICAL MEANS. THE VESSEL CONTAINING THE BLOOD SAMPLE IS ORBITED AROUND A DETECTOR ELEMENT AT A RELATIVELY HIGH SPEED TO ESTABLISH SHEARING EFFECTS AND RESULTING ELECTRO-KINETIC SURFACE EFFECTS BETWEEN THE INNER WALL OF THE VESSEL AND THE SURFACE OF THE DETECTOR ELEMENT CORRESPONDING TO THE SHEARING AND ELECTRO-KINETIC SURFACE FORCES PRESENT IN THE VEINS AND ARTERIES OF AN INDIVIDUAL. THE DETECTOR ELEMENT IS PART OF A CONVENTIONAL BLOOD ANALYSIS DEVICE WHICH MAY PROVIDE EITHER VISUAL OR RECORDED INDICIA REPRESENTATIVE OF THE COAGULATION CHARACTERISTICS OF THE BLOOD SAMPLE.
