Clinical Support Services
for Sleep Disorders.

Simple measurement with wristwatch-type devices can be used in the diagnosis of sleep disorders.
Screening target disorders: Insomnia, Circadian Rhythm Disorders, Central Hypersomnia.

Actigraph Sensor 'ACCEL ATRIA' Visual Image
Actigraph for Use
in Sleep Disorder Evaluation.

The Actigraph Sensor 'ACCEL ATRIA'*1 is a medical device equipped with an accelerometer to record patient body movements. As a wristwatch-type device, it can be easily worn on the wrist for measurement.

Generic Name: Actigraphy Sensor Registration Number: 40B2X10040000001.

ACCELStars Analysis Platform Visual Image
Analysis Cloud Equipped with a High-Precision Sleep Analysis Algorithm Developed Using PSG as Training Data.

When data measured by a wearable device is uploaded to the 'ACCEL Stars Analysis Platform' (ASAP), the algorithm automatically performs sleep/wake classification. It not only visualizes sleep states but also automatically aggregates sleep indices. Objective and rapid results can be used for evaluating sleep disorders.

Graph of 3-state measurement mode
Supports Three-State
Classification:
Wake/REM/Non-REM.

In addition to the two-state mode (Sleep/Wake), a three-state mode (Wake/REM/Non-REM) is also available.
