Multi-slide loading capacity and pneumatic atomization liquid spraying dyeing machine

Abstract

The invention discloses a multi-slide loading capacity and pneumatic atomization liquid spraying dyeing machine which comprises a base, a protective cover is arranged on the base, a protective cover cap is arranged above the protective cover, a dyeing pot is arranged in the protective cover, a rotary driving device located below the dyeing pot is further arranged in the protective cover, and a slide tray is arranged in the dyeing pot. The rotary driving device is detachably connected with a glass slide tray in the dyeing pot, a pneumatic atomizing and spraying mechanism is further arranged in the protective cover, a spraying opening is formed in the side wall of the protective cover, and the pneumatic atomizing and spraying mechanism sprays to a glass slide on the glass slide tray through the spraying opening; wherein the glass slide tray is a vertical insertion type glass slide rack or a laminated step type glass slide rack or a tiled type glass slide rack. The dyeing machine is simple in structure, convenient to use and good in dyeing effect, the three-dimensional space in the device is effectively utilized through the vertical insertion type slide frame, the laminated step type slide frame and the tiled slide frame, the loading number of slides is greatly increased while the size of the device is not increased, and superfine atomization dyeing is achieved through the pneumatic atomization spraying mechanism.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to a dyeing machine with a multi-slide loading capacity and pneumatic atomization and liquid spraying. Background technique [0002] There are currently three methods of staining pathological slides, bacteria and cell sheets at home and abroad: dipping, dripping, and spraying, among which spraying is the most scientific staining method. The existing automatic dip dyeing method is to manually move the hanging basket containing the sample slides back and forth from one dyeing vat to soak and dye with a manipulator agent; Move the dropper, suck and drop the dyeing solution through the liquid pump; the automatic machine of the dip dyeing method and the dripping method uses a manipulator to act as a substitute for traditional manual work, and its structure is simple. [0003] When staining slides by dip-dyeing method, the reagent tank used to supply the staining solution is op...

AI Technical Summary

Problems solved by technology

[0003] When staining slides by dip-dyeing method, the reagent tank used to supply the staining solution is open, the reagent is easy to volatilize, the reagent concentration will gradually decrease, and tissue sample fragments are prone to fall off in the reagent tank, which affects the quality of subsequent staining At the same time, the cross-contamination rate increases; when the concentration of the reagent is reduced, the staff needs to manually add a little fresh reagent to replenish it, which has many uncertainties. At the same time, the staff replenishes the reagent in a polluted environment, which will have an impact on the health of the staff

[0004] When staining the glass slides with the drip staining method, the disadvantages of the dip staining method can be avoided, but there are still the following problems: because the surface of the glass slides is smooth, the staining solution will slip away after being dropped on the glass slides, At the same time, the droplets are cohesive and will form large droplets or a few small droplets, resulting in uneven staining; in order to solve the above problems, a large amount of reagents are used to stain the slides by the drop staining method, and the slides are placed in the clips to allow The reagent is soaked on the surface of the glass slide, but at the same time it also causes the problem of large consumption of reagents and a large amount of waste liquid; when the staining method is used to stain the slide, it needs to be aligned and then dripped, so the drip staining method time consuming

However, because the spray dyeing method needs to use electromagnetic pumps to generate pressure (a pump that generates a lot of pressure), the cost of electromagnetic pumps is high, and a machine needs more than a dozen pumps, which is complicated to control. The holes and small groove nozzles, plus the dye reagent is a thick liquid containing crystals and impurities inside, which is easy to touch the holes. Every day after get off work, a large amount of alcohol must be used to flush the pipelines, and the reagents must be used to fill the pipelines when the machine is in use. At the same time, the droplets sprayed by the nozzle are not fine enough to form ultra-fine mist

[0006] In addition, the existing devices for staining glass slides by dip-dyeing, drip-dyeing and spray-dyeing still have the disadvantages of small number of loaded slides, large instrument volume, complex structure, many electronic control parts, high failure rate, and high cost. question
