AI Technical Summary

Technical Problem

Existing methods for measuring cerebrospinal fluid (CSF) pressure are time-consuming and prone to inaccuracies due to variations in spinal needle characteristics and require reference tables that may not be easily accessible, leading to prolonged measurement times and increased infection risk.

Method used

A method and device using signal generators and sensors to calculate the time constant and CSF pressure without needing spinal needle characteristics, employing a first-order differential equation and iterative calculation to determine the time constant and fluidity coefficient, enabling precise and fast measurements.

Benefits of technology

The solution allows for accurate CSF pressure measurement in under 60 seconds with three decimal place precision, eliminating the need for reference tables and reducing measurement time and infection risk.

Abstract

The invention relates to a method and a device using said method that determine the time constant and thus the cerebrospinal fluid pressure in order to calculate, at high speed and with high accuracy, intracranial pressure (ICP) measurements performed with a spinal manometer of the cerebrospinal fluid (CSF) pressure value, without requiring the characteristics of the spinal needle used for lumbar puncture.
