Design and Development of Wearable Device for Continuous Monitoring of Sleep APNEA Disorder

The sleep disorder is associated with a medical disorder where the normal sleeping pattern of the person is disturbed. Some sleeping disorder may lead to serious problems in physical, mental, social health of an individual and it may also intern fatal if it is left untreated. Some of the common types of sleep disorders are Sleep apnea, restless leg syndrome, narcolepsy, jet lag, Sleep-walking, Sleep paralysis. The usual method of diagnosing sleep apnea disorder is polysomnography which is carried out in a supervised clinic. It involves the complete and continuous monitoring of the certain parameters and body functions of the patient. Here in this proposed study, continuous sleep apnea monitoring device was developed which could detect spo2, blood pressure, heart rate in real time. A liquid crystal screen is used to show these parameters. The measured physiological parameters could be transferred from the device to the smartphone through Bluetooth or Wi-Fi, which could be used for further analysis. Based on the experimental results, this wearable device can provide reliable diagnostic results and a non- invasive blood pressure measurement was measured using a cuff less method. The developed low-cost device could avoid complicated procedure and gives continuous monitoring of sleep apnea disorder.
