(XLTEK) Photic Stimulator is used by trained medical staff in a medical environment to apply photic flashes to the patient during neurophysiology studies such as electroencephalographic (EEG) studies, where it is used as an activation to test photo-sensibility related to epilepsy.<br><br>The Natus Photic Stimulator is typically used by EEG technicians in the hospital environment in fixed, mobile or portable systems, and with patients of all ages. The lamp head assembly is mounted on an arm allowing easy placement at 30 cm away from the patient's face. The arm is ergonomically designed so that the lamp can be move and rotated in the direction of the patient using a handgrip on the lamp.<br><br>Trigger pulses applied to the trigger input of the Natus Photic Stimulator generate 1 millisecond photic flashes at specific frequencies, typically in the range of 0.5 Hz to 60 Hz by a white light emitting diode (LED) lamp. The basic operating mode consists of generating a single flash per trigger pulse applied. Flash intensity has a maximum range from 22,000 lux up to 75,000 lux measured at 30 cm from the LED lamp at the position of highest intensity and 3,520 lux to 12,000 lux calculated at 75cm. The frequency and intensity of the flash is controlled by the acquisition software.<br><br>It can also be used along with evoked potential devices for stimulating visual evoked potentials. | | | | <b>Intended Use:</b> | The Natus Photic Stimulator is indicated for photic activation of the EEG during an EEG study and in the generation of visual evoked potentials. | | | | <b>Technology Comparison:</b> | The Natus Photic Stimulator employs the same technological characteristics as the predicate device. | | | | System Characteristic | Lifelines Ltd.<br>Lifelines Photic Stimulator<br>(K101691) | Excel-Tech Ltd.
