A monitoring system and method based on linear relationship between intraocular pressure and intracranial pressure

Abstract

The invention belongs to the technical field of medical equipment and discloses a monitoring system and a method based on the linear relationship between intraocular pressure and intracranial pressure. The monitoring system comprises an information integration module, an intraocular pressure measurement module, a vital signs monitoring module, and a lumbar cistern pressure monitoring module. The intraocular pressure measuring module, the vital signs monitoring module, and the lumbar cistern pressure monitoring module are mutually independently connected with the information integrating moduleand do not affect each other. The vital sign monitoring module comprises an electrocardiogram monitoring unit, an invasive artery pressure monitoring unit and a dual-frequency electroencephalogram monitoring unit. The data are integrated through an information integration module for information display, information storage and integration with the information. Based on the linear relationship between intraocular pressure (IOP) and intracranial pressure (ICP), the system indirectly reflects the change of ICP by measuring IOP, and provides an effective non-invasive monitoring method for ICP during general anesthesia.

Description

technical field [0001] The invention belongs to the technical field of medical equipment, and in particular relates to a monitoring system and method based on the linear relationship between intraocular pressure and intracranial pressure. Background technique [0002] Intracranial pressure, that is, the pressure of cerebrospinal fluid in the cranial cavity, is normally 100-150 mm water column, 10-15 mm Hg; according to p325 of the practical skills guide for the national medical qualification examination, the pressure of cerebrospinal fluid in a normal adult lying position is 0.78-1.76kpa (80 ~ 180 mm water column) or 40 ~ 50 drops / min, fluctuating with breathing within 10 mm water column, children's pressure is 0.4 ~ 1.0 kPa (40 ~ 100 mm water column). Intracranial pressure monitoring is very important in cranial surgery and other operations involving changes in intracranial pressure. Since the intracranial is fluctuated by many factors, the pressure measured in a unit tim...

Problems solved by technology

[0003] To sum up, the problems existing in the existing technology are: the existing methods are invasive operations with many restrictions, and there are few non-invasive pressure monitoring methods, and a convenient and effective non-invasive continuous monitoring method needs to be invented urgently
