Intended Use

The Natus Photic Stimulator is indicated for photic activation of the EEG during an EEG study and in the generation of visual evoked potentials.

Device Story

Natus Photic Stimulator is an arm-mounted LED lamp assembly used by EEG technicians in hospital environments (fixed, mobile, or portable systems). Device receives trigger pulses from external acquisition software to generate 1ms white light photic flashes. Flash frequency (0.5 Hz to 60 Hz) and intensity (up to 75,000 lux at 30 cm) are controlled by the acquisition software. Used to test photo-sensibility related to epilepsy and to stimulate visual evoked potentials. Lamp head is manually positioned 30 cm from patient face via ergonomic arm and handgrip. Output provides visual stimulation to patient; healthcare provider observes patient response via EEG or evoked potential monitoring to aid in neurological diagnosis.

Clinical Evidence

Bench testing only. Performance verified against IEC 60601-1, IEC 60601-1-2, IEC 60601-2-40, IEC 60601-1-6, IEC 62366, IEC 62471, and ANSI Z80.36-2016. Results confirm compliance with predetermined specifications and safety standards.

Technological Characteristics

Arm-mounted photic stimulator; surface-mounted high-intensity LED array; 0.5-60 Hz flash rate; 22,000-75,000 lux intensity at 30 cm. Standards: IEC 60601-1, IEC 60601-1-2, IEC 60601-2-40, IEC 60601-1-6, IEC 62366, IEC 62471, ANSI Z80.36-2016.

Indications for Use

Indicated for photic activation of the EEG during an EEG study and in the generation of visual evoked potentials in patients of all ages.

Regulatory Classification

Identification

An evoked response photic stimulator is a device used to generate and display a shifting pattern or to apply a brief light stimulus to a patient's eye for use in evoked response measurements or for electroencephalogram (EEG) activation.
