An intracranial pressure monitoring system and method. The system includes an auditory stimulation and recording unit, which includes a stimulation controller, a memory for storing waveforms, a device for comparing received waveforms with stored waveforms, and an alarm operable based upon that comparison. The system includes at least one cranial electrode attachable to a patient, and an auditory stimulation device, operable by the stimulation controller. The stimulation device is a pair of acoustic ear inserts, each of which is connected to and operated by an auditory stimulator activated by the stimulation controller. In the method, a patient is auditorially stimulated to evoke a received waveform indicative of intracranial pressure, a comparison is generated by comparing the received waveform with one of an established patient baseline waveform and an established normal waveform, and an alarm is generated responsive to that comparison.

A system which includes a first sensor placed proximate to a perfusion field of an artery receiving blood which emanates from the cranial cavity is configured to monitor pulsations of the artery receiving blood which emanates from the cranial cavity artery. A second sensor placed proximate to a perfusion field of an artery which does not receive blood emanating from the cranial cavity and approximately the same distance from the heart as the first sensor configured to monitor pulsations of the artery which does not receive blood emanating from the cranial cavity. A third sensor placed distally from a heart is configured to monitor pulsations of a distal artery. A processing system responsive to signals from the first, second, and third sensors is configured to determine intracranial pressure.

The invention discloses an intracranial pressure monitoring drain tube and belongs to the technical field of intracranial drain tube devices. The drain tube comprises an intracranial pressure monitoring probe and a drain tube, wherein a rigid silicon rubber head is arranged at the front end of the drain tube, and a drain butt port is formed at the tail end of the drain tube; the intracranial pressure monitoring probe is embedded at the front end of the interior of the drain tube; a drain pore is formed on the lateral side of the drain tube; a rectangular hollow groove is formed in the middle of the intracranial pressure monitoring probe; a silicon substrate to which a pressure strain foil is attached is closely attached to the groove, and the periphery of the groove is completely sealed by silica gel; a first drain pore is formed on a part, corresponding to the pressure strain foil, of the top of the drain tube; and a thermocouple is arranged on the rigid silicon rubber head at the front end of the drain tube. By utilizing the intracranial pressure monitoring drain tube, the intracranial pressure is monitored in real time in an intracranial draining process, the hard silicon rubber head arranged at the front end causes less damage to brain tissues and nerve fibers; the first drain pore can be used for realizing drainage, and ensures that the pressure strain foil can be directly contacted with an external liquid, so that the monitored pressure is more accurate.
