The present invention provides a human body model apparatus for analyzing characteristics of a contrast medium. The apparatus includes: a pulse pump which pumps injected fluid; a damper which reduces high pressure when the damper receives the pumped fluid and the fluid flows; a tachometer which measures a flow rate after receiving the fluid of which high pressure has been reduced; a lung module which receives the fluid of which the flow rate is measured, generates resistance pressure to reduce pressure of a rear end portion by a predetermined level to be lower than pressure of a front end portion, and then discharges the fluid; and a control unit which adjusts pressure of the front end portion and the rear end portion by using an input variable and an output variable. The contrast medium is injected in a front end portion of the lung module. According to the present invention, a standardized injection amount of the contrast medium, injected in the front end portion of the lung module, can be set; the best video image can be obtained with the minimized injection amount of the contrast medium; and vortex or turbulence of waves, generated by high pressure of the fluid coming out of the pulse pump, can be prevented. |
