The Characteristics and Advantages of the Spo2 Sensor

The SpO2 instrument consists of three main components: the probe, the functional module and the display portion. For most of the monitors on the market, the detection SpO2 technology has been very mature. Whether the spo2 sensors value detected by the monitor is accurate or not obtained is largely related to the probe, in which many factors can affect the probe detection, the detection devices, medical wire and the connection process will affect the test results.

First, detecting device: a light emitting diode of the detection signal and the photodetector element are the core components of the probe and also the key to determine the accuracy of numerical detection. The theoretical red wavelength is 660nm, and the infrared light is 940nm when detected values obtained ideal, but due to the complexity of the process of manufacturing a device, produced by the red, the wavelength of the infrared light in the total deviation. The magnitude of the deviation of the wavelength of the light will affect the detected value. Therefore, the light emitting diode and the photodetector device manufacturing process, it becomes very important.



Second, Lead Wires: In addition to the use of imported materials (high elastic strength, corrosion resistance is very reliable), is also designed with a double shield, more than single-layer or no shield to suppress noise and maintain signal integrity.

Third, cushion: the probe produced by the R-RUI uses a specially designed cushion (pad), which is comfortable, reliable, allergic skin contact, and can be applied to the different shape of the patient. And is wholly wrapped design can be avoided to cause interference due to the light leakage of the movement of the finger.

Fourth, takes the fire-rated non-toxic ABS material, sturdy and difficult to be damaged. Finger clip design uses shading plate, which could better shield the peripheral light source.

Fifth, one of the main reasons that damage the general SpO2 is due to the loose spring, insufficient elastic and insufficient clamping force, and R-RUI takes the plated carbon steel springs with high tension, which is reliable and durable.

Sixth, terminal: In order to ensure a reliable connection of the probe durable, considering the attenuation in the signal transfer process, using special technology plated terminals on a connection terminal with monitor.

Seventh, connection technology: the connection process of probe is also very important for the test results, and the upholstered position has gone through the calibrated tests, in order to ensure the correct position of the detection device transmitter and receiver.

Eighth, in accuracy, ensuring SpO2 value is 70% - 100%, the error is not more than plus or minus 2%, the accuracy should be higher, so that the detection result is more reliable.
