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(jiàn)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(jiàn)病。而職業(yè)病體檢，會(huì)因行業(yè)不同而不同，多為塵肺病、噪聲耳聾、化學(xué)中毒、皮膚病、放射類(lèi)疾病等。設(shè)備種類(lèi)不同，設(shè)備需求不同：一方面，在設(shè)備種類(lèi)上，職業(yè)病體檢車(chē)會(huì)配備一些專(zhuān)項(xiàng)檢查設(shè)備。例如電測(cè)聽(tīng)及配套電測(cè)聽(tīng)室醫(yī)療車(chē)內(nèi)部空間有限，這就需要醫(yī)療車(chē)制造商依據(jù)每個(gè)用戶的個(gè)性化需求優(yōu)化布局設(shè)計(jì)，不僅滿足設(shè)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(shè)備，設(shè)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(chē)也常會(huì)配置DR來(lái)拍攝胸片，但是從事塵肺病檢查的業(yè)內(nèi)人士都會(huì)知曉，職業(yè)病體檢用DR與健康體檢DR有很大不同。在由國(guó)家衛(wèi)計(jì)委發(fā)布的相關(guān)標(biāo)準(zhǔn)中，對(duì)塵肺病攝影用DR有諸多明確的限制，在球管焦點(diǎn)、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).
