Early diagnosis of vibration disease research and preliminary proposals for the early diagnosis


Is based on the t (1) These changes are due to hand-arm vibration hazards, may not be accompanied by vibration of the tunnel with the emergence of white finger, and may appear in the white finger before. These changes indicate that not only subjective symptoms and objective investigation also proved that control the peripheral circulation and peripheral nerve disorders have occurred, already Ji-bed disease. (2) in foreign countries and organizations, scholars, diagnostic criteria or recommendations, nor is the oscillation means the only basis since, according to arise from the means other than the former and white refers to the clinical manifestations and objective examination, is the ability diagnosed vibration disease. (3) these changes have some contact with each other, Chi Tuo such as base refers to the group of nerve conduction velocity test Ling 58 * capacity and pressure after rewarming means test,[link widoczny dla zalogowanych], the subjective symptoms and peripheral circulation, neurological disorders beam tip, the tip of finger feel and the Ling test skin temperature, pressure refers to the test, while there is a certain correlation between these changes and specific non-arm vibration hazards,[link widoczny dla zalogowanych], indicating the need for comprehensive evaluation. Consider the feasibility, non-white / TL-type color vision tester in the head with a 9 �� of Industrial Medicine 1992 Volume 5, No. 1 refers to the interest rate:,[link widoczny dla zalogowanych], has yet to be further changes and the other aspects of the clinical significance of the base, but also to be into the a , tear effect of fluoride preliminary examination of color vision health and epidemic prevention station of Inner Mongolia Autonomous Region (010020). Inner disk built Zhao Hulunbeier epidemic prevention station commonly used in the transport sector pearl red and green lights, should a driver color vision, color vision can not be correct, it will cause traffic difficulties wrong signal. UK, USA, Germany, Japan, the Soviet Union and other countries in the driver's employment and periodic medical review of color vision in both attached great importance to the inspection, the method to map a multi-method, are also equipped with some lights, and hue matching method and test method f1 career in the Ministry of the physical examination is recommended. Lamp test method. There is no driver in our power examination argue color uniform methods and standards, the use of Yuzi Ping's Method for detecting color vision devices work force is inconclusive because of the quality of domestic products and foreign equipment is expensive and difficult to spread a wide range of models, it is reported to carry out small, only in the Sui Road locomotive crew had some professional inspection lamp test instrument made in Japan reported. For motor vehicle drivers to explore the occupational characteristics of the intuitive, convenient, sensitive and accurate detection method for color vision force, in January 1990 to 5 months in the Inner Mongolia Medical Hulunbeier motor vehicle drivers, we use the macro Ichikawa Japan's fake Light-type color vision tester TL-type color vision color vision tester checks carried out to investigate the performance and conditions, the results reported below. One object is the summer transfer method 1. T bang Lemberg survey League of Inner Mongolia that tile British force flag, Dong Autonomous County and Elgin Banner ancient variety of motor vehicle drivers of sodium, a total of 8389 people, aged between 16 to 62 years old, are male. !. Methods, (1) instrument method used and the Beijing Railway Labor Health Institute,[link widoczny dla zalogowanych], stationery factory jointly developed by TL = type of color vision inspection trick. Check in the scattered light, the subjects face the field of view while sitting 5 meters. Adjust the instrument and subject to the same elevation level. Color source for the red, green and yellow shade, within 2 seconds of longitudinal two-color light is lit. Shown in light shade during the color subjects to answer the name of each experiment, nine groups shade display. Check of attack, the two suspects re-examination and grading help. (2) atlas method selected Yue Bai Ping check map compiled in the bright light color blindness, the distance of 60 ~ 80cm,[link widoczny dla zalogowanych], according to the educational level of subjects in the selection of patterns or patterns of digits, each time identification shall not exceed 10 seconds, suspicious Two re-examination and grading by f3 'wrapped a method and apparatus map method detection rate out = 0.3> 0. Method and apparatus OS map of Table 2 test results depression compared I = 2554.59P <O. OO13. Sample screening index, (1) the subjects to be instrumental method, Figure scold Simultaneous examination, and suspicious if one of the methods to be both re-examination of two methods. (2) to check visual acuity, stereopsis, fundus, vision and so the exclusion of other suffering caused by the eye of sputum color vision. 4. TL One check mark heap search suspicious sub-t map of the oxygen check for color vision abnormalities, and normal instrument method. Light level: yellow or green occasionally read the wrong person for the green or yellow. King occasionally in red or green t read as green or red and / or frequently read as yellow or green or yellow by green. Heavy duty red or green t often read the wrong person for the green or red. (Occasionally refers to the nine read the wrong shade and under the three groups, often referred to as reading the wrong shade nine four or more.) Pei Results 1. Color blindness were found in detection of the Rotary 3389 drivers, instruments and patterns of color vision disorder detected were 158 and 164 were detected in 4.51 and 4.84%. After testing both methods no significant differences, see the decline of a pair of two grid search method has been designed to Z 'test, hair
