Innovative technologies of head injury physiological monitoring

Abstract

The World Health Organization estimates that in 2010 one of ten families in developed countries will have a member with head or spinal cord injury. The systems of head and spinal cord physiological monitoring as well as the treatment of injured patient according to the presence of diagnostic information allow us to decrease the mortality of patient and their invalidity. However, the existing head injury monitoring technologies are invasive. This paper analyses scientific and patent information designed for the development of non-invasive physiological monitoring technologies. Also the proposed technological solutions have been systematized. It is shown that innovative technologies for non-invasive monitoring of the cerebral blood flow autoregulation, cerebral blood volume pulse and slow waves also for the registration of the reactions to the neurodiagnostic tests can be developed on the basis of the precise measurement of brain parenchyma acoustic characteristics. The innovative technological equipment for such measurement has been developed. The clinical studies proving the validity of the concepts chosen have been carried out. For the first time the innovative non-invasive method was designed for the ICP absolute value measurement without the necessity of individual calibration of system "non-invasive meter - patient".
