Patent ID: 8620448

Claim:
A non-invasive, wireless, portable device applicable to the finger in order to reduce the risk of sudden infant death syndrome and the risk of apnea, slower heart rate, and heart arrest in all age groups, comprising: a) a sensor ( 1 ) delivering blood oxygen saturation measurement signal and a heart rate measurement signal; b) a power supply ( 9 ); c) means ( 11 ) for setting threshold values for blood oxygen saturation and heart rate; d) a control and alarm-generating circuit ( 7 ), wherein said control and alarm-generating circuit ( 7 ) is designed to receive said blood oxygen saturation measurement signal to compare it with a blood oxygen saturation threshold value predefined by the user and generate a stimulation signal if said blood oxygen saturation signal falls below said blood oxygen saturation threshold; e) a pair of metal electrodes ( 6 ); f) an electric stimulation generator ( 10 ) designed to receive said stimulation signal from said control and alarm measurement circuit ( 7 ) and to generate an electric signal that is connected to said pair of electrodes ( 6 ) to apply a stimulus to the user when the blood oxygen saturation falls below said threshold; wherein: said control and alarm-generating circuit ( 7 ) is designed to also receive said heart rate measurement signal and compare it with a heart rate threshold value predefined by the user and generate said stimulation signal if said hear rate signal falls below said heart rate threshold.
