摘　　要：目的了解西安市某医疗用品公司生产膜式氧合器过程中产生的职业病危害因素,明确该行业生产过程中职业病危害控制要点,并提出相应的补充措施和建议。方法根据相关法规、标准和规范,采用工作场所现场调查法、工作场所职业卫生检测法及工程分析法等,于2022年4—5月对西安市某医疗用品公司膜式氧合器生产过程进行综合分析。结果西安某医疗用品公司膜式氧合器生产环节产生的职业病危害因素为二苯基甲烷二异氰酸酯、二氯乙烷、环氧乙烷、紫外辐射和噪声等。正常生产过程中混胶、擦拭、灭菌操作人员接触二苯基甲烷二异氰酸酯(<0.00009 mg/m^(3))、二氯乙烷(<0.3 mg/m^(3))和环氧乙烷(<1.0 mg/m^(3));作业人员接触噪声8 h等效声级均<80 dB(A),属于非噪声作业岗位。结论西安市某医疗公司生产膜式氧合器过程产生的危害因素浓度或强度均符合限值要求,其中关键控制点为二氯乙烷擦拭和环氧乙烷灭菌岗位,生产企业应在擦拭工序设置局部通风设施;加强设备及防护措施的维护与检修,确保设备正常运行和防护措施有效,以减小有害因素对作业人员的健康影响;做好员工职业卫生培训,按时进行职业健康检查并完善相关健康档案。Objective To understand occupational hazards generated during the production of membrane oxygenators by a medical supplies company in Xi'an,clarify the key points for controlling occupational hazards in the production process of the industry,and propose corresponding supplementary measures and suggestions.Methods According to relevant regulations,standards,and specifications,a comprehensive analysis was conducted on the production process of membrane oxygenators by a medical supplies company in Xi'an in April to May 2022 using methods such as workplace on-site investigation methods,workplace occupational health testing methods,and engineering analysis methods.Results The occupational hazard factors generated during the production process of a membrane oxygenator in a medical supplies company in Xi'an were diphenylmethane disocyanate,dichloroethane,ethylene oxide,ultraviolet radiation,noise,etc.During the normal production process,mixing,wiping,and sterilization operators come into contact with diphenylmethane disocyanate(<0.00009 mg/m^(3)),dichloroethane(<0.3 mg/m^(3)),and ethylene oxide(<1.0 mg/m^(3)).The equivalent sound level of workers exposed to noise for 8 hours was less than 80 dB(A),and they belonged to non-noise work positions.Conclusion The concentration/intensity of the hazardous factors generated during the production of membrane oxygenators by the a medical company in Xi'an City meet the limit requirements.The key control points are dichloroethane wiping and ethylene oxide sterilization positions,and the production enterprise should set up local ventilation facilities in the wiping process.Strengthen the maintenance and repair of equipment and protective measures to ensure normal operation of equipment and effective protective measures,in order to reduce the impact of harmful factors on the health of operators.Provide occupational health training for employees,conduct occupational health examinations on time,and improve relevant health records.
