Influence of hemoglobin analyzer's light path system to the hemoglobin value

Hemoglobin measurement instrument hemoglobin as one of the medical devices, its light road system can affect the determination of hemoglobin.
Hemoglobin is the light road system including, light lamp power supply circuit, light lamp, lens group, filter, than color pool, photoelectric devices (test, cell), etc.
If the hemoglobin instrument light source power supply instability, filter is bad, ripple is too large, the power supply voltage is too low will affect light source the light of the luminous intensity, and the stability of light source, influence the accuracy of the test. According to the maintenance program at the circuit, the circuit debugging repair, to comply with the requirements. Dark and light source lamp light lamp aging luminous efficiency is reduced, impact test value, can make the test value is low. This time should clean the light bulb, or replace new light the lamp. If the lens group of dirty, the influence of the lens pervious to light degree, can affect test values. At this time to clean lens groups. Filters use time will damp, aging, born mildew or dirty, and impact test, this time should be carefully cleaning filter. If filter aging metamorphism, can affect filter center wavelength and filter of bandwidth. Thus influence test values, this time can only change new the same wavelength filter.
Hemoglobin instrument than the color of the pool of dirty, a flat affect test values, because dirty will not only influence through the intensity of light than color pool, if than color pool dirty and attached to the bubble, can make through the light of the pool than color reflected or scattering, the serious influence test results. At this time to clean all the necessary lubricious pool with protein, flush out fault for solvent.
Hemoglobin is photoelectric device the surface has dust or dirt can influence light receiving or optical signals conversion. Clean all this time, if the photoelectric device aging, can only be replaced.
Add: able to measure the hemoglobin value of medical devices include: urine analyzer, biochemical analyzer, etc.
