Development of the Intracranial Pressure and Intracranial Temperature Monitor and Experimental Research on Trauma

Objective A set of intracranial pressure and intracranial temperature monitor was developed. Moreover, it was verified to be effective in the monitoring of intracranial parameters by designed experiments.Methods The intracranial pressure and intracranial temperature monitor was tested in the water bath comparing with the Codman intracranial pressure monitor and mercury thermometers. As well, the monitor was applied in the monitoring of rat brain edema in vivo.Results The maximum error is less than 266.64 Pa in the intracranial pressure measurement compared to the Codman intracranial pressure monitor, and the maximum error is less than 0.3 oC in the temperature measurement according to mercury thermometers. Furthermore, the monitor could real-time obtain the intracranial pressure and intracranial temperature in the brain edema in vivo.Conclusion The intracranial pressure and intracranial temperature monitor realizes the real-time in vivo monitoring of intracranial pressure and intracranial temperature. The measurement accuracy meets the acquirement of doctors. The instrument has potential for clinical use.
