数字式颅内压力计的研制

Development of Digital Intracranial Pressure Gage

目的:研制数字式颅内压力计,用于检测颅内压力,为颅内压升高患者提供准确的颅内压力数据。方法:在颅骨顶部的合适位置钻一小孔,将内径为1mm左右的充满生理盐水的导管插入脑室,导管外端通过三通开关连接传感器,通过传感器把压力转换成电信号送到单片机C8051F020进行数据处理,并输出到LCD液晶屏显示压力。结果:该数字式颅内压力计可实现实时检测,其检测结果准确,能真实反映出颅内压力。结论:该数字式颅内压力计操作简单,读数直观,体积小,携带方便。

Objective To provide precise data of encephalic pressure of the patients with higher encephalic pressure. Methods Through a hole bored in the proper position on the top of skull, a lmm vessel, full of physiological saline, was inserted into the ventricle, whose outside was connected with the sensor through a 3-way stop cock. The sensor transformed the pressure into electrical signals and transmitted them to micro-computer C8051F020 for data processing. The value of pressure was then displayed on the LCD. Results Real-time and precise detection could be acquired by this intracranial pressure gage. Conclusion The digital intracranial pressure gage is easy-to-operate, simple and portable.
