<p>A wrist worn monitoring device for sufferers of chronic obstructive pulmonary diseases and coronary heart conditions is described. The device has a first sensor 17 adapted to monitor a heart rate associated with a user of the system; a second sensor 18 adapted to monitor a pulse oximeter oxygen saturation associated with a user of the system; a wearable wrist strap 16a, 16b carrying the first and second sensors and configured so as to locate the first and second sensors on a ventral surface of the wrist of a user of the device; a data collection module adapted to collect data from each of the first and second sensors; and a communication means adapted for wireless data transmission of the collected data to a remote processor. Examples of the heart rate sensor may include a piezoelectric sensor, audio sensor, or optical/light sensor for example an infra red sensor. The oxygen sensor may also be an infra red sensor for example a reflective photoplethysmography or PPG sensor. The device may also include a position sensor such as a GPS, or a movement sensor such as an accelerometer 22.</p> |
