单片机控制的颈动脉窦区自动灌流系统的研究

目的：建立一种自动控制颈动脉窦区灌流压的新方法。方法：采用AT89C2051单片计算机构成谦价实用的灌流控制器,钭它与LDB-M型电子蠕动泵、实验动物的颈动脉窦区构成自动灌流系统。结果及结论：该系统能对大鼠颈动脉窦区进行均匀斜坡升压,阶梯升压-降压灌流,并已用于压力感受器反射效应研究中,此系统能保证灌流曲线的准确性和可重复性。进一步提高了实验的技术水平。

An automatic system controlled by microcontroller for carotid sinus perfusion

Aim:To establish a new method for controlling automatically the carotid perfusion pressure.Methods: A cheap practical automatic perfusion unit based on AT89C2051 micro controller was designed. The unit,LDB M perfusion pump and the carotid sinus of an animal constituted an automatic perfusion system.Results and Conclusions: This system was able to provide ramp and stepwise up down perfusion pattern and has been used in the research of baroreflex. It can insure the precision and reproducibility of perfusion pressure curve, and improve the technical level in corresponding medical field.
