medicalfor diabetesOLED

Pulse oximeter provides a means of measuring oxygen saturation or arterial hemoglobin saturation in a non-invasive manner. Also detects pulsating arteries, so the patient's heart rate can also be calculated and informed.It is a medical device used to measure the amount of oxygen in a patient's arterial blood.The principle is based on changes in the amount of light absorbed during pulse.Main structure: composed of microprocessor, memory, digital to analog converter, small liquid crystal display, light-emitting diode, photosensitive receiver and other components. Core advantages: small body easy to carry, multiple data monitoring, over-limit alarm, 8 seconds value, screen rotation, intelligent power saving, international certification. With the ability to resist natural light interference and power frequency interference, it can effectively shield the interference of ambient light to the measurement.8 seconds automatic shutdown energy saving and environmental protection, high-definition large screen data at a glance, high quality environmental protection materials, durable.
