无线多用户颅内压监护仪的设计及应用

The Design and Application of Wireless Multi-user Intracranial Pressure Monitor

实现颅内压的无线监护目前已经成为临床医疗的最新发展方向。作为颅内压无线监护仪中首要的组成部分,传感器放大电路及其附加电路发挥着相当重要的作用。以无线多用户颅内压监护仪的设计为例,给出了颅内压无线监护仪的体系结构和原理框图,论述了传感器及其放大电路的设计方法,介绍了其他附加转换电路的设计过程,最后针对在设计微弱信号(μV级)放大电路时遇到的实际问题进行了分析,提出了具体的解决办法。

The newest clinical therapy development direction is the implementation of wireless monitoring of intracranial pressure. As the essential part of the wireless intracranial pressure monitor, the sensor＇ s amplifier circuit and other associated circuits play a very important role. This paper takes the design of intracranial pressure wireless monitor as an example to illustrate the following four parts： first, the system structure and block diagram of operation principle for wireless monitor of intracranial pressure; second, the design of the sensor＇ s amplifying circuit in the medical instruments ; third, the design of other associated circuits ; at last, it also analyses the problems possib the same time it suggests some solutions lely encountered during designing of weak signal sensor circuit and in to these oroblems.
