In vivo non-invasive intracranial pressure monitoring device and method based on meningeal absorbance changes

Abstract

The present innovation unveils a non-invasive in vivo intracranial pressure (ICP) monitoring device and method relying on meningeal absorbance changes. Comprising a signal excitation module, spectral data acquisition module, and data processing module, the device incorporates a laser and optical parametric oscillator in the signal excitation module. Optical path adjustments are facilitated by concave lenses and convex lens mirrors between the laser's output and the optical parametric oscillator's input. The optical parametric oscillator's output is equipped with a coaxial lens group and a fiber bundle. This approach ensures non-invasive ICP monitoring, providing ease of use, precision, reliability, and continuous dynamic monitoring, significantly reducing patient discomfort during ICP monitoring. The method offers an objective foundation for disease diagnosis, condition assessment, and the formulation of effective diagnosis and treatment strategies, showcasing substantial clinical potential.
