Fingertip Pulse OximeterThis Fingertip Pulse Oximeter is a kind of innovated medical device with non-invasive and continuous features for artery SPO2 and PR detection. Being portable， it is able to measure SPO2 and PR values quickly and precisely.Product Operation ScopeThe fingertip Oximeter can be used to measure human haemoglobin saturation and heart rate through finger. The product applies to using in family， hospital (including clinical use in internist/surgery， anaesthesia， paediatrics， intensive care， etc.)， oxygen club， social medical organizations， physical care in sports (It can be used before or after sports. Operation in sport procedure is not recommended).
