ABSTRACT:
An apparatus simulating blood circulation in the human body which allows sphygmic diagnosis simulation to be performed by measuring simulated arterial pulses along a simulated artery portion which simulates an artery portion leading to either the left or right hand of the blood circulating system of the human body. The simulated artery portion is included in a simulated blood circulating passage formed by a layout of tubes representative of the human circulatory system. Each tube has a circular section of rubber resin made of both silicon and natural rubbers in which the wall thickness of the tube, Young Modulus, tensile strength, dimension, and compliance are predetermined to simulate the human body. Sphygmic diagnosis simulation can be performed by measuring the simulated arterial pulses at three points along of a radial artery portion corresponding to three positions of shun, khan, and shaku of the sunko as in the practice of Oriental medicine. Three pressure sensors may be used to detect the simulated pulses and blood circulation at the shun, khan, and shaku spots of the sunko. Information on blood viscosity, artery hardness, and inner wall condition is also obtained.
