Flushing device for staining in pathology department

Abstract

The invention relates to a pathological section staining technology, in particular to a flushing device for staining in the pathology department. The flushing device comprises a tank body; the tank body is used for containing water, and a partition plate slidably penetrates through the tank body and divides the tank body into an upper cavity and a lower cavity; a water outlet is formed in the peripheral wall of the tank body; the upper end of a telescopic rod of the telescopic cylinder is fixedly connected with the lower end of the partition plate, and the lower end of the telescopic cylinder is fixedly connected with the lower bottom wall of the tank body; the telescopic cylinder is electrically connected with a controller; a tank cover comprises a cover body, the cover body is used for covering the upper end opening of the tank body, a cavity between the cover body and the partition plate is used for containing water, a through via hole is formed in the upper end of the cover body, a threaded rod movably penetrates through the via hole in a sleeved mode and is in threaded connection with a nut, and a liquid level sensor is fixed to the lower end of the threaded rod; the liquid level sensor is electrically connected with the controller; and a water valve is arranged on a hose; one end of a pipeline is communicated with one end of a water outlet through the hose, and the lower side face of the pipeline is fixedly connected with a supporting plate. With the flushing device adopted,water flow speed is constant, a slice tissue is not washed away, and the water temperature is controllable.

Description

Technical field [0001] The present invention relates to pathological slice staining techniques, and more particularly to a flushing device for pathological branch staining. Background technique [0002] The pathological sections are, take a certain size of lesions, and make pathological sections in pathological histology [usually treat the lesions, according to different requirements, the slice machine is made into different thicknesses: frozen slices, paraffin slices, fire cotton rubber slice, Paraffin semi-thin slices, resin embedded semi-thin slices, etc. Sumu - Inghong (He) staining, special staining and immunohistochemical staining, etc., and then further examined the lesion with a microscope. [0003] During the production, the pathological sections require multiple dyeing treatment slices; for example, the sliced ​​dewaxing is ethanol to water, and the water is washed into the nucleus into the nucleus, so that the cell nuclear staining, the water washing after dyeing is no...

Problems solved by technology

[0004] At present, the slices are generally placed under the faucet for washing, but the size of the water flow of the faucet is related to the pressure of the water delivery equipment in the area, the water flow speed is not easy to control, and the faucet directly flushes the slices, which is easy to wash away the pathological tissue on the slices and the temperature of the water flow It is not suitable to control the pH of the water flow (due to some regional differences, most tap water tends to be acidic, which has an impact on dyeing, and warm water can increase the pH of the water to a certain extent), bluening after differentiation, and termination of color development, etc. (with the external temperature, the water temperature in winter Significantly lower, the molecular movement slows down, which has a certain impact on the reaction, and the flushing time must be prolonged, but the prolonged flushing time will increase the risk of tissue detachment to a certain extent) all have a certain impact
