PRIMA Finger pulse oximeter for adults

This Finger Pulse Oximeter is an innovative type of medical device with non-invasive and continuous properties, used for the detection of arterial SPO2 and PR parameters. Being portable, it also has the possibility to measure SPO2 and PR values quickly and precisely. The device contains batteries. The working principle of the pulse oximeter is as follows: an experimental formula is established for data processing using Lambert Beer's Law according to the spectral absorption characteristics of reducing hemoglobin (R Hb) and oxyhemoglobin (O2 Hb) in the luminescence and near-infrared areas. The operating principle of the instrument is to combine the Oxyhemoglobin Photoelectric Inspection Technology with Pulse Measurement and Recording Technology so that two lights with different wavelengths (660 nm luminescence and 940 nm near-infrared light) can be focused on the human nail by means of a finger grip type of sensor. The measured signal can be obtained with the help of a photosensitive element, and the information obtained through it will be displayed on two groups of LEDs through processing in electrical circuits and a microprocessor. Properties: • OLED screen • The product displays on a two-color OLED screen, it can display in six distinct modes • The interface can display four different modes (useful for the accelerometer function of the tool) • It has low energy consumption, it can operate continuously for more than six hours with two AAA batteries • Battery power indicator • In the absence of signals, the product will go on standby • Small volume, lightweight, and convenient to carry • The instrument has a function of automatic detection of the 5s signal, it will start when the finger is inserted; Automatic Start function Operating instructions 1. Install two AAA batteries in the battery box before closing the cover 2. Insert a finger into the rubber hole of the oximeter (it is best to insert the finger completely) before releasing the clamp with the nail up. 3. Press the button on the front panel; (Note: if it is equipped with the automatic start function, there is no need to press the button, the instrument has a 5s automatic signal detection function; insert your finger directly and the instrument will start automatically) 4. Do not move your finger during the operation of the Oximeter. It is not recommended to move the body during this time interval; 5. Press the button on the front panel, if you want to change the direction of the display; (Note: for the accelerator function do not press the button; the accelerometer instrument has four corresponding interface switches) 6. Read the relevant data displayed on the screen. 7. The instrument has the Sleep function, if no signals are recorded, the instrument will enter Sleep standby mode; 8. Please change the batteries in time when the OLED indicates that the batteries have low energy. Brief description of the Front Panel OLED screen; Start key; Battery cover OLED screen modes: description of key functions: in standby mode, start the instrument with the start key. Pressing the start key when the device is turned on can change the display mode. Note! Tools with accelerator function, OLED screen display mode, 1.2.3.4., there is no interface for large font according to 5.6 Detailed description of the product functions 1. Screen Type: OLED screen 2.
