【摘要】 颅内压监测是神经外科病人的常规护理方法,新型监测设备的研发一直是研究热点之一。随着传感器和无线技术的快速发展,小型化、微创化、多参数监测和遥测是目前的主要发展方向。本文重点研发了一套基于无线网络的颅内压监测系统,该系统能够连续测量病人的颅内压力和温度,通过无线网络将实时监测数据发送至PC机,并通过监护软件进行颅内压监护管理,医护人员无需离开护士站就可以浏览病区内病人的颅内压状况。本文主要研究内容和创新点:(1)完成了颅内压监测系统的硬件研制。主要工作包括:设计并制作能够同时测量颅内压力和温度的监测探头,颅内压监护仪主机和无线通信模块的硬件电路。(2)完成了系统的软件设计。主要工作包括:开发基于μC/OS-Ⅱ的颅内压监护仪主机的嵌入式软件,实现了对颅内压力及颅内温度信号的采样处理、界面显示和报警等功能;设计无线通信模块的嵌入式软件,实现了无线网络的建立和数据传输;设计监护软件,实现了对多病人的同时监护。(3)完成了监测探头的综合定标,并对压力传感器进行了温度补偿,取得了很好的补偿效果。(4)完成了系统的动物实验验证。自制颅内压监护仪和Codman颅内压监护仪在同时监测动物颅内压时的数据接近一致,验证了自制颅内压监护仪测量结果的准确性。更多还原

【Abstract】 Intracranial pressure(ICP) monitoring is a routine nursing method for nursing patients in Department of neurosurgery and the development of new monitoring equipment is always one of the research hotspots. Benefiting from the development of the sensors and the wireless technology, monitoring equipment are becoming miniature, minimally invasive, capable of monitoring multi parameter and wireless controlled. This paper focuses on the research and development of an ICP monitoring system based on wireless network, which can continuously measure the patient’s intracranial pressure and temperature, send real-time monitoring data to PC through the wireless network and monitoring and management of intracranial pressure by monitoring software. Therefore, status of the patients’ ICP is able to be monitored by medical staff remotely in the nurse station.The main research contents and innovations of this paper:(1) Hardware designing of the monitoring system, including manufacturing of the monitoring probe with the functions of ICP and temperature measurement, designing circuit of the ICP monitor and wireless communication module.(2) Software designing of the monitoring system, including development of the embedded software of ICP monitor based on μC/OS-Ⅱ to realize the processing and displaying the intracranial pressure and temperature, exceeding threshold alarm, designing the software of wireless communication module to realize the establishment of wireless network and data communication and designing the monitoring software for simultaneous monitoring of multiple patients.(3) Calibration of the ICP monitoring probe is completed, and the temperature effect of the pressure sensor was well compensated.(4) Animal experiment was carried out to test the system. Animal ICP data was recorded simultaneously by homemade ICP monitor and Codman monitor. The results of two groups of experiments were consistent, which verified the accuracy of the measurement results of homemade ICP monitor.更多还原
