Abstract: A device for non-invasive monitoring of intracranial pressure (ICP) may include a sensor, a processor unit, a device for recording electrical activity of the heart, and a device for invasive measurement of arterial blood pressure. The sensor monitors mechanical movements caused by bloodstream dynamics. A mathematical model and a relation between the start of a R-wave and a time delay of a mechanical movement of a patient's head are used to determine the ICP. A device for monitoring patient's vital functions may also measure respiratory and heart rate. The sensor may employ a piezoelectric transducer, which may form a measuring electrode of a measuring capacitor. In addition, a comparator capacitor may be used to increase resistance in changes in measuring conditions. Data from a plurality of measuring devices may be collected and processed in a cascading manner.

Abstract: The device for non-invasive monitoring of intracranial pressure (1) includes a measuring mat (2), processor unit (3), displaying device (6) and a network connector (7). The measuring mat includes the processor unit (3) and sensors, at least one sensor (8) monitoring mechanical movement caused by the bloodstream dynamics. The ICP calculation methods use the Windkessel model and the relationship between the first and second signal, which is related to the reflection of the pulse wave in the head. The method of relative changes of the intracranial pressure is based on an analysis of the bloodstream dynamics using the Moens-Kortweg equation.
