1980年1月下旬,我们对南川县庆岩机械厂手锤校工和铆校工57名接触振动的工人,作了生产环境调查,询问病史,体格检查,血管功能试验及手骨X线摄片检查。对振动所致的雷诺氏现象进行观察。并以本厂机动科59名工人作对照组,结果如下: 1.手持大锤和鎯头校正工所致手指雷诺氏现象的工人,全身症状仍以神衰为主。由于生产环境噪声强度高达128dB,造成耳鸣和心悸的症状显著增多,手的症状,除雷诺氏现象外,握力也明显下降。为了校正,需增加握力去握紧工具和钢板,于 In late January 1980, we conducted a survey of production environments, medical history, physical examination, vascular function tests, and hand-bone radiographs of 57 workers who were exposed to vibrations by hammer handlers and rivets school workers at Qingyan Machinery Factory in Nanchuan County. Film inspection. The phenomenon of Raynaud’s vibration caused by the observation. And 59 workers in our department of maneuver as a control group, the results are as follows: 1. Hand-held sledgehammer and head correction workers caused by finger Raynaud’s phenomenon, systemic symptoms are still the main god failure. As the production environment noise intensity up to 128dB, resulting in significantly increased symptoms of tinnitus and palpitations, hand symptoms, in addition to Raynaud’s phenomenon, the grip also decreased significantly. In order to correct, need to increase grip strength to clench tools and plates, at
