【摘要】 基于传感器技术、单片机技术、无线通信技术和LabVIEW虚拟仪器开发出的无线中心静脉压监护系统,采用NPC-1210作为压力传感器,STC89C52单片机作为接收器控制模块,通过通用串行总线(universal serial bus,USB)串口将压力数据传输至LabVIEW开发软件,实现对中心静脉压数据的采集和存储,并利用互联网技术将相关信息及时传送到医护人员手中.该系统使用了模块化的设计思路,通用性强、易于维护、操作简单、体积小,应用前景广阔,是一种用于替代医护人员执行繁琐的中心静脉压测量工作的可行系统.更多还原

【Abstract】 We develop a central venous pressure( CVP) monitoring system by using the sensor technology,singlechip microcomputer( SCM) system technology,wireless communication technology and LabVIEW software. The designed system uses NPC-1210 as the pressure sensor and STC89 C52 as the master controller chip. It communicates with LabVIEW software through universal serial bus interface. The CVP data,which is saved in computer,can be accessible to doctors and nurses. The system uses the modular design idea,is versatile,easy to maintain,simple to operate,small in size,and has broad application prospects. It is a viable system for replacing medical staff to perform cumbersome central venous pressure measurement work.更多还原
