Grabbing device used for blood cell analyzer

Abstract

The invention belongs to the technical field of medical apparatus and instruments, and especially relates to a grabbing device used for a blood cell analyzer. The grabbing device comprises a guide rail, an installation pedestal, and a fixing pedestal; the installation pedestal is arranged on the guide rail; the fixing pedestal is arranged on the installation pedestal; the fixing pedestal comprises a bottom plate, a side plate, and a top plate; the base plate and the top plate are arranged on the two ends of the side plate respectively; the top plate is provided with a bushing; the bushing is penetrated through by a grabbing guide rod; one end of the grabbing guide rod is connected with a lead rod; a bearing is arranged in the lead rod; an eccentric pin is arranged in the bearing; the eccentric pin is arranged at the eccentric part of a circular disc; the center of the circular disc is provided with a rotating shaft; and one end of the rotating shaft is connected with a motor. The grabbing device is simple in structure; operation is stable and reliable; assembling complexity is reduced; it is convenient for assembling and maintenance; moving and positioning accuracy is high; operation is smooth; the grabbing device is durable; service life is long; processing is convenient; and cost is low.

Description

technical field [0001] The invention relates to the technical field of medical and health instruments, in particular to a grasping device for a blood cell analyzer. Background technique [0002] Blood cell analyzer is one of the most widely used instruments in hospital clinical examination. With the rapid development of computer technology, blood cell analysis has also changed from three-dimensional to five-group, from two-dimensional space to three-dimensional space, and we have also noticed that modern blood cell The analyzer's five-differentiation technology uses the same technology as today's most advanced flow cytometers, such as scattered light detection technology, sheath flow technology, laser technology and so on. [0003] In the existing blood cell analyzer, the test tube sample needs to be transported to the designated position by the dragging device for sampling, so as to realize the automatic sampling function. During the sample conveying process, the grasping ...
