生化样本前处理系统中样本容器自动开盖装置设计

Design of automatic cap opening device for specimen container in the specimen pretreatment system of biochemistry analyzer

目的:设计一款能够去除橡胶盖及螺旋盖的生化样本前处理系统自动开盖装置,可兼容不同规格的样本容器与容器盖,解决现有样本容器开盖设备适应性差、结构复杂及可靠性低等问题。方法:由夹持机构、开盖机构、提升机构、旋转机构和废盖回收机构5部分构成自动开盖装置,样本容器盖的加紧及旋转采用同一个动力元件。结果:新型自动开盖装置适用于CS-6400等系列全自动生化分析仪,可有效提高生化样本的检测效率,减少交叉污染,降低了样本容器制造成本和维护费用,增大了系统的可靠性。结论:所设计的自动开盖装置,可解决目前样品容器开盖装置存在适应性差和可靠性低等技术问题,满足临床检验实用化的需要。

Objective: To design a new automatic cap opening device consists of holding mechanism, open mechanism, improve mechanism, rotating mechanism and recycling mechanism in order to resolve the poor adaptability, complex structure and lower liability problem for specimen container in the biological specimen pretreatment system. Methods: Thispaper designed a automatic equipment to remove the rubber cap and screw cap. This equipmentis compatible with the different specification specimen containers and the container cap, and the specimen container cap was stepped up and rotated with same power component. Results: The application ofequipment has reduced the manufacturing cost and maintenance cost for specimen container, improved the system reliability, solved the current technical problems of the equipment, such as poor adaptability and lower liability.Conclusion: The design of equipment mainly adapts to CS-6400 series of automatic biochemical analyzer, and it can improve the detection efficiency of biological specimen, reduce the cross contamination and satisfy the practice necessity for clinical detection.
