The invention provides a stimulation device of time-phase characteristics of coronary
artery blood flow, which relates to the technical field of
in vitro stimulation experiments and aims at solving the technical problems that the existing hemodynamic parameters of clinical patients and experimental animals have randomness and the
blood flow is difficult to be measured. The device comprises a fluid line
system which consists of a cardiac pump, an accumulator, a fluid flow loop and a fluid
storage tank which are sequentially and circularly connected, and a motor which drives the cardiac pump to move; and the device is characterized in that: the fluid flow loop comprises a two- position three-way valve, a diastolic
branch and a systolic
branch; one end of the diastolic
branch and the systolic branch is respectively connected with two outlets of the two-position three-way valve, and the other end is connected with the fluid
storage tank, a common inlet of the two-position three-way valve is connected with the accumulator, and the two-position three-way valve is driven by the motor to cause the common inlet to be communicated with the diastolic branch and the systolic branch along with the alternation of the
diastole and the
systole of the cardiac pump, and fluid resistance of the systolic branch is greater than that of the diastolic branch. By adopting the stimulation device of the invention, the time-phase characteristics of the coronary
artery blood flow can be reproduced.
