Title:
人工心臓ポンプを管理する方法
Document Type and Number:
Japanese Patent JP7166633
Kind Code:
B2
Abstract:
In a method for managing a cardiac pump intended to assist the heart of a patient, the cardiac pump sends pressurized blood at a flow rate proportional to the speed of rotation Vrpm of the pump through the aortic valve of the heart. The steps, during a same ventricular systole, include: detecting mitral valve closure, rotational speed Vrpm of the pump being strictly less than a maximum value Vrpm max, increasing Vrpm of the pump such that, at time t2, after the time t corresponding to the closing of the mitral valve, the speed of rotation of the pump is equal, or substantially equal, to the maximum value Vrpm max of the speed of rotation, and keeping the speed of rotation Vrpm of the pump at this maximum value Vrpm max for at least a portion of the time period T during which the aortic valve is open.
