Description
技术领域technical field

背景技术Background technique
在生化检验领域,在进行生化检验时需要先进行加样操作,再进行搅拌操作,因此需要使用到加样装置和搅拌装置,加样装置是在反应杯中加入样本,加样仪器只有一根针,也负责加试剂,而搅拌装置则是根据设置,在加入试剂、稀释液等之后进行搅拌,以加速反应进程,均匀反应体系。In the field of biochemical testing, when performing biochemical testing, it is necessary to add samples first, and then to perform stirring operations, so it is necessary to use a sample adding device and a stirring device. The sample adding device is to add samples into the reaction cup, and there is only one The needle is also responsible for adding reagents, and the stirring device is set to stir after adding reagents, diluents, etc., to speed up the reaction process and uniform the reaction system.
在现有生化仪技术层面,加样装置与搅拌装置往往因为运动轨迹和性能技术层面参数的不同,而分别配置与设计;通俗来讲,生化仪的加样装置与搅拌装置在设计之初就因性能指标不同而独立设计为两种完全不同的生化仪组件,没有考虑两者通用性。At the technical level of the existing biochemical instrument, the sampling device and the stirring device are often configured and designed separately due to the difference in motion trajectory and performance technical parameters; Two completely different biochemical analyzer components are independently designed due to different performance indicators, without considering the versatility of the two.
因为医疗生化设备的特性,在生化仪设备上,需要大量使用加样装置和搅拌装置来提高生化分析仪的性能,往往运行速度越快的生化分析仪,使用的加样装置与搅拌装置越多。Due to the characteristics of medical biochemical equipment, it is necessary to use a large number of sampling devices and stirring devices to improve the performance of biochemical analyzers on biochemical equipment. Often, the faster the biochemical analyzer runs, the more sampling devices and stirring devices are used. .
而且基于理论分析,加样装置与搅拌装置在底层的运动原理又有很大重合,具体来讲,上述两种装置都是基于某特定轨迹运行,基于此两者在通用性方面有可行性;所以单独配置生化的加样装置与搅拌装置无形中浪费较多的物料成本和管理成本。Moreover, based on theoretical analysis, the movement principles of the sampling device and the stirring device at the bottom overlap greatly. Specifically, the above two devices are based on a specific trajectory, and based on this, both are feasible in terms of versatility; Therefore, separate configuration of biochemical sampling device and stirring device virtually wastes more material cost and management cost.
因此,亟需解决上述问题。Therefore, it is urgent to solve the above problems.
