The team’s devices compute the pressure differential between the inside and the outside of the skull, based on a quick and simple reading obtained from a sensor placed on the patient’s eye. Acta neurochirurgica 11, Ragauskas’ novel measuring devices are important tools for treating intracranial injuries, which are among the world’s deadliest killers. Societal benefit Traumatic brain injury TBI and central nervous system tumours rank among the leading causes of death worldwide.

A non-invasive method for continuous real-time monitoring of cerebrovascular blood flow autoregulation state includes simultaneous non-invasive monitoring of intracranial blood volume respiratory waves and lung volume respiratory waves, real-time decomposition of intracranial blood volume respiratory waves and lung volume respiratory waves into narrowband sinewave first harmonic components, determination therefrom of the phase shift between intracranial blood volume respiratory wave and lung volume respiratory wave first harmonics’ and derivation of cerebrovascular autoregulation state from that phase shift value.

Traumatic brain injury TBI and central nervous system tumours rank among the leading causes of death worldwide.

Arminas Ragauskas (Lithuania)

Ultrasound to safely measure brain pressure The invention of two devices for measuring intracranial pressure and blood flow by Lithuanian scientist Arminas Ragauskas enables fast and safe diagnosis of traumatic brain injury, strokes, glaucoma and brain tumours. A method and apparatus for continuously measuring the absolute intracranial pressure in a non-invasive manner is described by using an ultrasonic Doppler device which detects the pulsatility indexes of the blood flow inside the eye armiinas for both intracranial and extracranial eye artery portions.

The system can’t perform the operation now. Brought to market intwo medical devices developed by Ragauskas and a team of fellow Lithuanian scientists give neurologists and other doctors precious extra time to detect and assess increased cranial pressure. New articles by this author.

Finalist for the European Inventor Award Videos: Method and apparatus for continuously monitoring intracranial pressure. They no longer need to resort to costly and time-consuming invasive surgery, which itself is not without risk. Brought to market intwo medical devices developed by Ragauskas and a team of fellow Lithuanian scientists give neurologists and other doctors precious extra time to detect and assess increased cranial pressure.

President’s blog Patent information: Quick response times are essential when diagnosing brain injury, especially when a brain trauma or tumour elevates cranial pressure to potentially lethal levels. Patent information events Consult arminad calendar.

Ratauskas apparatus is operated by pressuring both chambers, and pumping a blood-imitating fluid through the vessel in a pulsatile manner. The eye in which the blood flow is monitored is subjected to an external pressure, sufficient to equalize the intracranial and extracranial angle-independent blood flow factors calculated from the intracranial velocity signal and extracranial velocity signal. Traumatic brain injury TBI and central nervous system tumours rank among the leading causes of death worldwide.

EPO – Arminas Ragauskas (Lithuania)

Ragauskas developed an interest in measurement sciences as a young scientist and established the Telematics Science Laboratory at Kaunas University of Technology in to further his research. They are a major improvement over invasive surgery, for which srminas have to be anaesthetised.

In Europe, roughly 2. When the waveforms of arterial wall movement between the intracranial segment and the extracranial segment are similar the intracranial pressure can be determined. Official Journal email alerts Get the latest issues delivered direct to your inbox Subscribe now.

The Lancet Neurology 16 12, In Europe, roughly 2. Ragauskas – along with colleagues Gediminas Daubaris and Algis Dziugys from the Health Telematics Science Institute at Kaunas University of Technology, Lithuania – achieved a breakthrough by applying the Doppler wavelength effect in order to arrive at an accurate reading of cranial pressure, using an ingeniously simple formula.

Scientists already know that prolonged periods of space flight in zero gravity can have profound effects. Eye 29 10, The heart, for instance, tends to become more spherical and lose muscle mass due to the lack of gravity, which can cause problems on return to Earth.

New citations to this author. The heart, for instance, tends to become more spherical and lose muscle mass due to the lack of gravity, which can cause problems on return to Earth. The eye in which the blood flow is monitored is subjected to a small pressure, sufficient to equalize the pulsatility index measurements of the internal and external portions of the eye artery.

Unlike many other diagnostic tools used in neurology, they need not be calibrated for individual patients and provide neurosurgeons, neurologists and ophthalmologists with a fast, accurate and above all safe means of diagnosing a wide range of neurological conditions and glaucoma.

Is non-invasive monitoring of intracranial pressure waveform analysis possible? The inventor’s measuring devices are currently being used by the US National Space Biomedical Research Institute at a facility run by the German Aerospace Centre DLR in Cologne to investigate the effects of ragwuskas spaceflight conditions on brain physiology.

All eyes are now on NASA’s Scott and Mark Kelly, the only twins ever tested for the effects of long-duration space travel on the human body. Method and apparatus for non-invasive continuous monitoring of cerebrovascular autoregulation state A Ragauskas, G Daubaris US Patent 8, This applied external pressure is then compared to the autonomous intracranial pressure ICP.

The elastic film expands inward toward the patient with an inflow of pressurized liquid, imparting a pressure against the patient’s eye. Intensive care medicine 34 9,
