Non-invasive, wireless, portable device applicable to the finger to reduce the risk of sudden infant death syndrome and reduce the risk of apnea, slower heart rate, and heart arrest in all age groups

摘要

Disclosed is a non-invasive, portable device applicable to the finger or toe in order to reduce the risk of sudden infant death syndrome and the risk of apnoea, slower heart rate, and heart arrest in all age groups. The device is comprised of: a) a sensor section (1) including a blood oxygen saturation sensor delivering a blood oxygen saturation measurement signal and a heart rate sensor delivering a heart rate measurement signal; b) a power supply section (9); c) a control and alarm-generating circuit (7), d) a pair of metal electrodes (6); and e) an electric stimulation generator (10). The control and alarm-generating circuit (7) is designed to receive the blood oxygen saturation measurement signal, compare it with a blood oxygen saturation threshold value predefined by the user and generate a stimulation signal if the blood oxygen saturation signal falls below the blood oxygen saturation threshold. The control and alarm-generating circuit (7) is designed to also receive the heart rate measurement signal, compare it with a heart rate threshold value predefined by the user and generate the stimulation signal if the heart rate signal falls below the heart rate threshold. The electric stimulation generator (10) is designed to receive the stimulation signal from the control and alarm measurement circuit (7) and to generate an electric signal applied to the pair of electrodes (6) to apply a stimulus to the user when the blood oxygen saturation falls below the threshold. The electrodes (6) are located on the sides of the blood oxygen saturation sensor. All elements a) - e) are contained in the same housing and do not require wiring to external elements.
