Uniform mixing mechanism, automatic uniform mixing device and sample analyzer

Abstract

The invention relates to the technical field of medical equipment, and particularly discloses a uniform mixing mechanism, an automatic uniform mixing device and a sample analyzer, the uniform mixing mechanism is used for driving a test tube to swing so as to uniformly mix a sample in the test tube, and the uniform mixing mechanism comprises a first fixing plate, a second fixing plate, a rotating block and a clamping piece; and the rotating block is arranged on the second fixing plate, the clamping piece is fixedly installed on the rotating block and used for grabbing or releasing a test tube, the second fixing plate is detachably connected with the first fixing plate, and the second fixing plate and the first fixing plate are movably matched to achieve fine adjustment of the position of the clamping piece. In this way, fine adjustment of the position of the clamping piece can be achieved, so that assembly and manufacturing errors are corrected, and it is guaranteed that test tubes can be accurately grabbed or placed.

Description

technical field [0001] The present application relates to the technical field of medical equipment, in particular to a mixing mechanism, an automatic mixing device and a sample analyzer. Background technique [0002] In clinical testing instruments, such as blood cell analyzers, it is necessary to fully and reasonably mix the blood samples contained in the test tubes in the test tube sample rack before testing and sampling. Therefore, each blood cell analyzer includes multiple modules. [0003] During the long-term research and development process, the inventor of the present application found that due to the inevitable processing errors in the manufacturing process and the assembly and manufacturing errors generated in the assembly process, the clamping parts would deviate from the test tube rack or relay components, resulting in the inability to accurately grasp Failed to take or place the test tube. [0004] Therefore, it is necessary to propose a mixing mechanism, an a...
