YH-600A Pro


YH-600A Pro records the following data: patient respiratory nasal
airflow, snoring, blood oxygen saturation, pulse and wrist
movement during sleep. It can also be connected to a CPAP
system to record and display continuous positive airway pressure.
The device uses these recordings to produce a report that may
aid in the screening of sleep disordered breathing or for further
clinical investigation. The device is intended for the hospital /
institutional environment (supervised) and the home environment
(unsupervised) for adult.


• Sleep study is the test used to diagnose sleep disorders. • IT records brain activity and oxygen level in your blood heart rate and breathing as well as eye and leg moment during the study. • The normal process of falling asleep begins with a sleep stage called Non rapid eye moment sleep. • Sleep apnea or another sleep related breathing disorder: It breathing repeatedly stops and starts during sleep. • Periodic limb movement’s disorders: It involuntarily flex and extend your leg while sleeping. It sometimes associated with restless leg syndrome. • Narcolepsy: It overwhelming daytime drowsiners and sudden attack of sleep in that condition. • REM sleep behavior disorder: This sleep disorder involves acting out dreams as you sleep. • Unusual behavior during sleep: It unusual activities during sleep such as walking moving around lot of rhythmic movements. • Chronic insomnia: It trouble falling asleep or staying asleep. • A sleep lab monitors the following parameters like brain waves, Eye movements, Heart rate, Breathing pattern, Blood oxygen level, Body position, Chest and abdominal movement, Limb movement, Snoring and other noise you make as you asleep.

Benefits & Specifications

• The performance and functional characteristics of YH-600A Pro include all the user-friendly features of the predicate device.
• YH-600A Pro is powered by one 1.5 V AA battery. Testing was performed to demonstrate that the performance of YH-600A Pro in its intended environment is as safe and effective as that of the legally marketed predicate devices.
• The safety and effectiveness of the YH-600A Pro were verified through performance-related testing that consisted of Electrical Safety, Electromagnetic Compatibility, Mechanical and Environment Testing.
• The recorded data, such as SpO2, pulse rate, airflow waveform, snore and CPAP pressure, can be replayed on a computer via the PolyLogic Analysis Software which is provided with YH-600A Pro.
• The Sleep Screener can be used as a standalone unit for recording data. It can also interact with a commercially available IEC60950-1 compliant computer, which can be used to review data.
• The Sleep Screener does not have any audible alarms, and therefore, should not be used for continuous monitoring.
• The patient is an intended operator, who can safely use all functions and can perform all maintenances mentioned in the User Manual.
• All parts of the device are applied parts
• Polywatch YH-600A can be used in hospitals and families to meet different application scenarios.
• The device is light, easy to wear, has friendly human-computer interaction and a real-time screen displays of waveforms and parameters.
• Professional analysis software, with cross-platform data compatibility, can generate diagnostic reports for clinical reading. Portable design meets the mobility requirement.
• Its simplicity and lightweight features give you a better sleep care. It multiple parameters detection will provide you reliable and monitory data.
• Automatic sleep indentify and CSA detection gives a accurate diagnosis
