摘要

详细介绍了一种多普勒流量计和植入所需的改造。由于只植入了部分电子器件，因此必须引入锁相环以保持流量测量的方向性。该装置在体内和体外均能正常工作。本文给出了狗同种肺移植后主动脉和肺动脉的血流研究结果。

Detailed description of an implantable directional Doppler flowmeter.

A Doppler flowmeter and the necessary modifications for implantation are described in detail. Since only part of the electronics was implanted a phase-locked loop had to be introduced in order to keep the flow measurement directional. The proper working of the apparatus is demonstrated in vitro and in vivo. As an example the result of flow studies in the aorta and the pulmonary artery after homotransplantation of the lung in dogs are given.
