Automatic blood film making and dyeing instrument

Abstract

The invention belongs to the technical field of medical detecting instruments, relating to an automatic blood film making and dyeing instrument operating in a disc rotating mode. The automatic blood film making and dyeing instrument provided by the invention is characterized in that a sample feeding and film pushing disc is adjacent to a dyeing disc, a shifting fork is arranged between the sample feeding and film pushing disc and the dyeing disc, the sample feeding and film pushing disc and the dyeing disc are respectively driven by virtue of stepping motors to rotate, and the shifting fork shifts the blood film into a corresponding empty dyeing box on the dyeing disc when the film discharging station of the sample feeding and disc pushing disc is rotated to the joint of the sample feeding and disc pushing disc and the dyeing box entering station of the dyeing disc, thus the whole film making and dyeing process is completed. The automatic blood film making and dyeing instrument provided by the invention has the advantages that the operational mode of rotating the disc is utilized to substitute the operational mode of linear motion while the direction is changed for multiple times in the prior art, the use of a transmission belt and an automatic manipulator is greatly reduced, the overall structure is simple and compact, and the manufacturing cost is low; and besides, the stability and reliability of the instrument can be improved, all the processes are tightly arranged around corresponding stations of the rotating disc owning to an implementation device, thus all the stations can simultaneously operate and the operational efficiency is improved.

Description

Technical field [0001] The invention belongs to the technical field of medical detection instruments, and relates to an automatic blood smear preparation and staining instrument, in particular to an automatic blood smear preparation and staining instrument operating in a rotating disk operation mode. Background technique [0002] The automated blood smear preparation and staining instrument is the current development trend of blood cell morphology detection. While improving the accuracy of blood analysis results, it reduces the degree of manual participation and improves the efficiency of microscope detection. [0003] Generally, the automated blood smear preparation and staining process includes loading, sample loading, pushing, blood film drying, staining, cleaning, blood smear drying, and discharging. Each process is relatively independent and carried out in sequence. Existing automated blood smear production and staining instruments, in order to achieve this operation process,...

Problems solved by technology

However, considering that if only linear motion is used, the whole machine will be too large due to the long running stroke. Therefore, after a single process is completed, this type of instrument will change the running direction of the blood smear and enter the next process, such as blood smear drying. After completion, the running direction is rotated 90 degrees and enters the blood smear dyeing box; after the blood smear is loaded, the blood smear runs straight to a fixed stroke, and the running direction is rotated 90 degrees again to enter the dyeing process; blood smear dyeing and drying are completed After that, the running direction is rotated ...
