Patent WO-2020259357-A1 (WO)
Inventor: LI JINSHAN
IPC: A61B17/12
Filed: 2020-06-17
Abstract: A coronary venous perfusion system and a control method therefor. The system comprises an internal blood flow control device and an external control module. The internal blood flow control device comprises a blocking and filling unit. The blocking and filling unit, in a filling state, blocks blood in a coronary venous vessel from flowing back to the right atrium from cardiac muscle cells, and restores the blood flow in a contraction state. The external control module comprises a signal receiving unit and a control unit. The signal receiving unit is used to receive a body monitoring signal. The control unit controls filling and contraction operations of the blocking and filling unit on the basis of the body monitoring signal being fed back. The control unit controls, on the basis of the body signal for determining whether the cardiac muscle is ischemic, the filling and contraction operations of the blocking and filling unit. The blocking and filling unit, in the filling state, blocks coronary venous blood flow, such that the blood in the vein flows backwards into the venous microcirculation of the cardiac muscle to fully perfuse an ischemic myocardial region, thereby ensuring myocardial blood supply and avoiding myocardial injury caused by no-reflow.
