We developed a new circulation-assist device that can generate pulsatile assist flow synchronized with the patient's diastolic phase. The device is composed of a drainage tube, a centrifugal pump, an oxygenator, and a sending tube. A portable magnetic valve device composed of a pulse generator and a tamper, which produces intermittent mechanical compression, is attached to the pillow of the sending tube. Preliminary animal experiments were conducted. No changes in the animals' hemodynamics or any device problems were observed during a preliminary 48-h test run. Significant diastolic augmentation was confirmed. This new device may be useful in treating patients with severe heart failure and could be more useful than using percutaneous cardiopulmonary support (PCPS) alone.
我们研发了一种新型循环辅助装置，该装置能够产生与患者舒张期同步的搏动性辅助血流。该装置由引流管、离心泵、氧合器和输送管组成。一个由脉冲发生器和夯锤组成的便携式电磁阀装置，可产生间歇性机械压迫，连接在输送管的枕形部位。进行了初步动物实验。在初步的48小时测试运行期间，未观察到动物血流动力学变化或任何装置问题。证实了显著的舒张期增强。这种新装置可能对治疗严重心力衰竭患者有用，并且可能比单独使用经皮心肺支持（PCPS）更有用。
