生理信号采集卡虚拟设备驱动程序的设计

The Design of the Virtual Device Driver for Physiological Signals' Acquisition Card

基于Microsoft Windows98平台的网络睡眼监护系统,利用VTOOLSD开发生理信号采集卡虚拟设备驱动程序(VxD) 在VxD中实现IRQ的虚拟化,钩挂中断处理程序,实时处理硬件中断,采集心电、脑电等多路生理信号。这样,可以充 分发挥Win98的优势,使得网络睡眠监护系统能够满足家庭保健和社区医疗的需求。

In the project of the network sleep monitoring on Microsoft Window 98,we design a virtual device driver (VxD) for physiological signals acquisition card with VTOOLSD, in which we have accomplished IRQ virtualization, hook interrupt handling program, real-time processing of hardwave interruption and collection of ECG, EEG and other medical signals. The application of this method in family care and community medical treatment is encouraging.
