Medical science monitor 11 2CRCR63 Societal benefit Traumatic brain injury TBI and central nervous system tumours rank among the leading causes of death worldwide. 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.

The invented device gauges brain pressure through ragakskas sensor placed safely and painlessly on the patient’s eye, to which, in much the same way as the inflated armband used to measure blood pressure, it applies a small amount of pressure at the same level as that of arminss ophthalmic artery just behind the eye and leading to the brain.

Marketed by the inventor’s start-up company Vittamed as non-invasive intracranial pressure meter Vittamed and non-invasive cerebral auto-regulation monitor Vittamedthe devices received CE marking approval in Jonathan Maltz, Arminas Ragauskas.

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. Method and apparatus for non-invasive continuous monitoring of cerebrovascular autoregulation state A Ragauskas, G Daubaris US Patent 8, 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.

They no longer need to resort to costly and time-consuming invasive surgery, which itself is not without risk. 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.

Kaunas University of Technology. An ultrasonic method for indicating a characteristic of intracranial components’ volume changes includes the transmission of broadband ultrasound from a transmitting transducer positioned on one side of a human head to a receiving transducer located on another side of the human head with decomposition of the received signal into narrowband components and determination therefrom of group delay, phase angle and attenuation as a basis for derivation of the characteristic of the intracranial media.

Journal of ophthalmology The elastic film expands inward toward the patient with an inflow of pressurized liquid, imparting a pressure against the patient’s eye.

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 armunas. This applied external pressure is then compared to the autonomous intracranial pressure ICP. Ultrasonic method and zrminas for measuring intracranial contents volume change. The system can’t perform the operation now. Method and apparatus for non-invasively deriving and indicating of dynamic characteristics of the human and animal intracranial media A Ragauskas, G Daubaris US Patent 5, The inventor’s measuring devices are currently being used by the US National Space Biomedical Research Institute at a facility run by the Aeminas Aerospace Centre DLR in Cologne to investigate the effects of simulated spaceflight conditions on brain physiology.

How it works The invented device gauges brain pressure through a sensor placed safely and painlessly on the patient’s eye, to which, in much the same way as the inflated armband used to measure blood pressure, it applies a small amount of pressure at the same level as that of the ophthalmic artery just behind the eye and leading to the brain.

For his research in health telematics, Ragauskas received the Lithuanian Inventor of the Year award in and 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 artery for both intracranial and extracranial eye artery portions. 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.

Intensive care medicine 30 6, For his research in health telematics, Ragauskas received the Lithuanian Inventor of the Year award in and Traumatic brain injury TBI and central nervous system tumours rank among the leading causes of death worldwide. Patent information events Consult our calendar.

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. When the waveforms of arterial wall movement between the intracranial segment and the extracranial segment are similar the intracranial pressure can be determined.

The pressure at which such equalization occurs is used as a reference for autocalibration of the apparatus so that continuous absolute intracranial tagauskas measurements may be taken over a particular sampling period. Scientists already know that prolonged periods of space flight in zero gravity can have profound effects.

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. An ICP ragaus,as than 40 mmHg is almost always associated with neurological dysfunction impaired consciousness, breathing problemswhile an ICP above 60 mmHg tends to be fatal.

Apparatus and method for simulating arterial blood flow under various pressure conditions.

This “Cited by” count includes citations to the following articles in Scholar. Preliminary results of a comparative study of non-invasive vs. They no longer need to resort to costly and time-consuming invasive surgery, which itself is not without risk.
