[Trial production of non-invasive monitoring system from the anterior fontanelle on intracranial pressure].
The aim of utilizing P-50 Statham transducer as one of the monitoring systems for intracranial pressure consists in the case for its attachment and simplified identification of the zero point and calibration which are of problem for operation as in the cases of electrocardiogram and respiration. The P-50 transducer is a semiconductor strain gage transducer which was developed for the measurement of blood pressure. By attaching the foot plate of it, the applanation principle could be applied and the measurement from the anterior fontanelle could be made feasible. The accuracy of the measurement in this manner could be confirmed by various experiments. Being a semiconductor strain gage, it could be made into an extremely small weight, which made it most adequate for continuous measurement. Although some problems have been left yet to be clarified relative to the method for the fixation, it can be deemed to be fully applicable as one of clinical monitoring systems for intracranial pressure.
