Description

Technical Field

[0001] The present invention relates to the field of in vitro diagnostic medical devices, and specifically, to a microplate washer for in vitro diagnostic medical devices and an in vitro diagnostic medical device. Background Art

[0002] In vitro diagnostic medical devices refer to medical devices that obtain clinical diagnostic information by detecting human samples (blood, body fluids, tissues, etc.) outside the human body, and then judge diseases or the functions of the body. Some existing in vitro diagnostic medical devices include a microplate washing module for washing microplates (such as an automatic enzyme-linked immunosorbent assay analyzer). However, such microplate washing modules generally have the problems of long washing time and slow washing efficiency. Moreover, the working efficiency of other modules of such in vitro diagnostic medical devices is relatively high (that is, the microplate washing module is the short board of such in vitro diagnostic medical devices, and the microplate washing module restricts the analysis and diagnosis efficiency of such in vitro diagnostic medical devices). Therefore, such in vitro diagnostic medical devices usually have multiple microplate washing modules. However, due to various restrictions (such as the limitation of the space size of the analysis platform), such in vitro diagnostic medical devices usually cannot set enough microplate washing modules to match the working efficiency of other modules.

[0003] In view of this, there is a need in the art for a microplate washer for in vitro diagnostic medical devices that can improve the microplate washing ability of in vitro diagnostic medical devices. Summary of the Invention
