1 、 Trace element instrumentation principle: This instrument use optics principle, is inspected through the lens gathering enlargement production the nail the picture, on the television or the monitoring device demonstrated the naked eye cannot see the thing, carries on the analysis, then draws the conclusion, uses in to examine the human body orthopedics to need the mineral substance element (calcium iron zinc selenium and so on) is whether normal and so on
2 、 Trace element instrumentation operating procedure
A, the lens insertion videography handle, then clockwise rotation and is fixed
b 、 In videography the handle segment plug insertion fuselage handle receptacle, pays attention to the receptacle the direction
C, inserts a video frequency output line end to the fuselage video output (video out) in the receptacle, another end peg grafts to the television video frequency (video) in the receptacle
D, turns on the television, the program adjusts the video frequency (AV) in the frequency channel 。
E, this instrument power source plug insertion home use power source, turns on the fuselage the power switch, this time in the lens small lamp shines, explains the instrument already normal work.

F, grips the handle, causes the lens round orifice tightly to paste, to aim at the nail and the slow migration, obtains sharp image until the television on.
G, in order to achieve the desired effect, please use the color tv set
3 、 Trace element instrumentation examination result ： The normal person's nail obtains picture, general smooth ruddy also rich gloss, but lacks the mineral substance element patient's nail because insufficiently hard, is very easy to damage, obtains the picture ruggedly, has the irregular crack or the damage phenomenon (normal person nail which hard scratches is obtained pictur crack is straight, generally is regular also are very few) and so on, the detailed situation, please to experienced deeply helps doctor to consult.

4 、 Trace element instrumentation use matters needing attention: This instrument is one kind of precision instrument, must carefully protect to the lens and videography the handle, when does not use, please switch off the power source, and reorganizes.

Lacks the zinc sickness (like chart)
Lacks the zinc dwarfism, the height grows very slowly, short stature , the digestion function obvious □draws back, appetite bad, easily □the sending perleche, the second sexual characteristic maldevelopment, the breast do not grow, the reproductive organ hypoplasia, the organism resistance reduces, easily infects, male sterile, diabetes, hypertension, is pregnant □the embryo abnormally, the childbirth unusual, the sense of taste □draws back, has a poor appetite, losses of appetite, pica the intelligence low, records □the strength difference, the academic record difference, the four limbs incapably, the disposition hot tempered excitedly, is easy to move much, the skin dry, is rough, does not have the gloss, □sends, The diarrhea, the lethargy, the depression, the wound wound heal is not good, dark adaptation the ability reduces, nail floccosoids, anemia, liver splenomegaly

The selenium deficient performance mainly is escapes sends, escapes the armor, the partial patients have the skin symptom, the minority patient may have the nerve symptom and the tooth harm. The person is mild or moderate lacks the selenium, its indication or the symptom are not obvious. The human body lacks the disease which the selenium possibly produces: energy deficiency the malnutrition, the blood soluble anemia, the Keshan disease, the Kaschin-Beck disease, the hypertension, lack the courage and uprightness heart disease, the liver cirrhosis, the pancreatitis, the fibroma, the cancer, the myo- lump, the sterility, the diabetes, the cataract and so on
