Abstract: During the treatment of neurosurgical patients, the changing of intracranial pressure (ICP) monitoring is the main monitoring objects, while most of the clinical equipment are wireline. With the rapid development of transducer and wireless network, miniaturization, micromation and wireless transmission become one of the research hotspots. This paper designed a wireless ICP monitoring system based on ZigBee technology, which can continuously measure the patient's intracranial pressure and temperature, and send monitoring data of patients of different ward to nurse station through the wireless network, and save it. Then we can inquiry the intracranial pressure and temperature using the intracranial pressure monitoring and management software we designed. The wireless system can be installed in the hospital very conveniently, which can reduce the work intensity of medical staff. The system is very useful in clinical work.
