Development of Digital Intracranial Pressure Gage / 医疗卫生装备

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 1mm 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.
