A health care band operably attaches a biosensor to a patient. The biosensor includes one or more sensors for collecting vitals of a patient and a wireless transmitter that is configured to communicate with an EMR network that stores and maintains an EMR of the patient. The biosensor stores a unique identification associated with the patient's EMR such that vitals measured by the biosensor may be transmitted with the patient's unique identification for storage in the patient's EMR. The sensors in the biosensor may include a thermometer, motion detector/accelerometer, pulse detector and oximeter, etc. In an embodiment, one of the sensors in the biosensor includes a photoplethysmography (PPG) based sensor that may be configured to continuously or periodically measure a patient's vitals, such as heart rate, pulse, blood oxygen levels, blood glucose or insulin levels, or other blood analytics in vitro.
