SpO2 instrument includes probe, function module and display part of the three main components. For most monitors on the market, the technology for detecting SpO2 is well established. Detected by a monitor SpO2 value is accurate or not, largely related to the probe, which affects the probe detection of many factors, the probe used in the test device, the medical wire, the connection process will affect the test results.

(1) detection device: detection signal light-emitting diodes and photodetection devices are the core components of the probe. It is also the key to determining whether the value of the test is accurate or not. Theoretically, the wavelength of red light is 660nm, and the value of infrared light is 940nm. The value of the detection is ideal, but due to the complicated process of manufacturing the device, the wavelength of the red and the infrared light is always deviated. The size of the deviation of the light wavelength will affect the detected value. So light-emitting diodes and photodetectors manufacturing process becomes very important. R-RUI uses Fu Luoke testing equipment, both in terms of accuracy, or reliability are very advantages.

(2) Medical wire: In addition to the use of imported materials (in the high elastic strength, corrosion resistance are reliable), also designed with double shielding, monolayer or no shielding more than noise suppression to maintain signal integrity .

(3) Cushion: The probe produced by R-RUI uses a specially designed cushion, which is comfortable and reliable, has no allergy to the skin and can be applied to patients with different body shapes. And uses a full wrap design, to avoid leakage due to finger movements and lead to interference.

(4) Finger Clip: The body refers to the folder using non-toxic fire-resistant ABS material, hard and not easy to damage. On the finger clip is also designed with a mask, you can better shield the peripheral light.

(5) One of the main causes of general SpO2 damage is that the R-RUI uses high tension galvanized carbon steel springs for reliability and durability due to loose springs and insufficient spring force to insufficient clamping force.

(6) Terminals: In order to ensure reliable connection of the probe, it is durable. Consider the attenuation during the signal transmission. On the connection terminals with the monitor, the special process gold-plated terminals are used.

(7) Connection Process: The connection process of the probe is also very important for the test results. The position of the cushion is calibrated to ensure the correct position of the transmitter and the receiver of the test device.

(8) Accuracy, to ensure that the SpO2 value of 70% - 100%, the error does not exceed plus or minus 2%, higher accuracy, making the test results more reliable.
