Finger Tip Pulse Oximeter
Introduction:
This device intended for use in measuring and displayingfunctional oxygen saturation of arterial hemoglobin (%spo2)and pulse rate (PR).The device measures Spo2 and PR with aspo2 senor and displays on the OLED after certain furtherprocessing, it can be used to measure human HemoglobinSaturation and heart rate through finger.
The Oximeter intended to be used for home care and medicaloutpatient measure pulse oxygen saturation and pulse rate ofadults .Oximetry is suitable for vascular diseases, respiratorydiseases, the elderly over the age of 60, working more than 12hours a day, extreme sports and alpine hypoxia environment ofblood oxygen monitoring population and chronic alcoholism
Measuring principle
Oximeter is based on the measuring principle haemoglobin,oxygenation of hemoglobin in the red and infrared lightabsorption characteristics in the region on the basis of theapplication "LamnertBeer"Law of data presented.
The instrument works by photoelectric detection of bloodoxygen combined with the pulse volume recording
technology, specific process is as follows:
First, the emission wavelength of used fluorescent tubes660nm Red and wavelength 940nm Near-infrared light
irradiation on the nails by photosensor measured signal.Thisinformation about wavelength range can be especially usefulto clinicians
