Sonqao, through its three physical examination centers in China’s Beijing and Inner Mongolia, provides physical checkup and personalized health management services.

Dehaier Medical Systems CEO Ping Chen said: "Since early this year, hundreds of wearable sleep diagnostic systems we delivered to hospitals and private physical checkup centers have performed well with increasing use for patients for sleep disorders.

"By the end of the first quarter, we have distributed 250,000 disposable PPG sensors to our regional agents that are actively delivering them to medical institutions all over the China."

Under the deal, Dehaier will supply its sleep respiratory solution systems, including related data transmission working stations, cloud-based diagnostic and analysis software, watch-sized sleep diagnostic and monitoring devices and disposable photoplethysmography (PPG) sensors.

These sleep respiratory solution systems will meet the demand for obstructive sleep apnea (OSAS) diagnosis and treatment at Sonqao’s physical examination facilities.

In January this year, Dehaier also agreed to provide its sleep respiratory solution systems to another physical examination chain Ciming Healthcare Group in China.
