The main service target of occupational health examination is enterprises with occupational disease hazards, which account for more than 30% of the total number of enterprises in the country. They are distributed in more than 30 industries such as mining, chemical industry, metallurgy, building materials, and chemical industry. Most of them are located in remote areas and have a large number of people, so on-site physical examination is a necessity for these enterprises. So, all medical institutions that want to provide occupational health examination services need mobile medical examination vehicles. Specifically, they need occupational mobile medical examination vehicles because there are significant differences between occupational disease examination and health examination in many aspects. The diagnosis of diseases varies depending on the tested population: Most general health examinations are non medical examinations aimed at healthy or sub healthy individuals who are not yet ill, are newly ill, or are about to become ill. The tested population can be children, youth, middle-aged, elderly, and other age groups, as well as people from various industries. The occupational disease physical examination is mainly aimed at young and middle-aged people who are engaged in or may be engaged in operations that are exposed to occupational disease hazards.

健康體檢的常見疾病為高血壓、高血脂、糖尿病、肺炎、肺結(jié)核、乳腺增生等常見病。而職業(yè)病體檢，會因行業(yè)不同而不同，多為塵肺病、噪聲耳聾、化學中毒、皮膚病、放射類疾病等。設備種類不同，設備需求不同：一方面，在設備種類上，職業(yè)病體檢車會配備一些專項檢查設備。例如電測聽及配套電測聽室醫(yī)療車內(nèi)部空間有限，這就需要醫(yī)療車制造商依據(jù)每個用戶的個性化需求優(yōu)化布局設計，不僅滿足設備的使用需求，還要確保體檢流程的高效順暢。另一方面，即使看上去相同的設備，設備的具體需求也是不同的。

Common diseases in physical examination include hypertension, hyperlipidemia, diabetes, pneumonia, tuberculosis, breast hyperplasia and other common diseases. The occupational disease physical examination may vary depending on the industry, mainly including pneumoconiosis, noise deafness, chemical poisoning, skin diseases, radiation related diseases, etc. Different types of equipment have different equipment requirements: on the one hand, in terms of equipment types, occupational disease examination vehicles will be equipped with some special inspection equipment. For example, the internal space of medical vehicles equipped with electric audiometry and supporting electric audiometry rooms is limited, which requires medical vehicle manufacturers to optimize the layout design based on the personalized needs of each user, not only to meet the equipment usage needs, but also to ensure the efficient and smooth medical examination process. On the other hand, even devices that appear the same have different specific requirements. Taking DR as an example for common pneumoconiosis examinations,

健康體檢車也常會配置DR來拍攝胸片，但是從事塵肺病檢查的業(yè)內(nèi)人士都會知曉，職業(yè)病體檢用DR與健康體檢DR有很大不同。在由國家衛(wèi)計委發(fā)布的相關標準中，對塵肺病攝影用DR有諸多明確的限制，在球管焦點、濾線柵參數(shù)、AEC控制、源像距（SID）等方面也均有明確要求。

Health examination vehicles often use DR to take chest X-rays, but industry professionals engaged in pneumoconiosis examinations are aware that there is a significant difference between using DR for occupational disease examinations and using DR for health examinations. In the relevant standards issued by the National Health and Family Planning Commission, there are many clear restrictions on the use of DR in pneumoconiosis photography, and there are also clear requirements in terms of tube focus, filter grid parameters, AEC control, and source image distance (SID).
