METHOD AND APPARATUS FOR DETERMINING THE PRESSURE INSIDE THE BRAIN |
摘要 |
An apparatus for measuring the intracranial pressure in a non-invasive manner is described by using an ultrasonic Doppler device which detects the velocities of the blood flow inside the optic artery for both intracranial and extracranium optic artery portions. The eye in which the blood flow is monitored is subjected to a small pressure, sufficient to equalize the blood flow measurements of the internal and external portions of the optic artery. The pressure at which such equalization occurs is found to be an acceptable indication of the intracranial pressure. Various devices are illustrated and used to enable either an automatic or manual intracranial pressure measurement. |
