Flat plate type pathological toaster and water-draining device thereof

Abstract

The invention discloses a draining device for a flat-plate pathological roasting machine. The draining device includes a V-shaped bracket, a wedge-shaped support base and absorbent cotton. The absorbent cotton is laid on the V-shaped bracket, and the V-shaped bracket is fixed on the V-shaped bracket. on the wedge-shaped support base; the present invention also discloses a flat-plate roasting machine comprising the above-mentioned water-absorbing device, including a roasting table, the forward inclination angle of one side of the V-shaped support of the draining device is adjustable, and The front plate of the film stage is tightly combined. The flat-plate pathological roasting machine and the draining device thereof disclosed by the invention can quickly eliminate the water film between the paraffin tissue section and the glass slide, thereby preventing the expansion and displacement of the paraffin tissue section.

Description

technical field [0001] The invention relates to the technical field of pathological slice machines, in particular to a flat plate type pathological slice machine and a draining device thereof. Background technique [0002] The production of pathological tissue paraffin sections is a complicated and continuous operation process. Slicing, spreading, scooping and baking are the four most basic steps. It is necessary to control the temperature, humidity, slicing speed, strength and other aspects during the operation. , in order to produce a satisfactory paraffin section. First, cut a tissue wax band with a thickness of 2-4um from the embedded tissue wax block, gently clamp it with tweezers, and then quickly spread it on the water surface at about 42°C, and use the tension of water and the appropriate temperature to remove the wax band. The fine wrinkles on the sheet are unfolded to obtain a complete wrinkle-free wax sheet. Then use glass slides to pick up the wax slices in the...

Problems solved by technology

Then use glass slides to pick up the wax slices in the water, pick up one or more slices according to the standardized requirements of pathological technology, and arrange them neatly in the middle and lower 1 / 3 of the slides, and then put the slides on a baking sheet at 70°C Bake the slices on the table for 15 minutes before performing various stains. The purpose is to make the tissue more firmly attached to the glass slide. However, in actual work, it was found that there is a layer of water between the tissue wax slice and the glass slide. The film and wax slices are not completely adsorbed on the glass slide, but float on the water film. In conventional pathological film production, the flat-bed constant temperature pathological roasting machine is one of the necessary equipment for pathological technology. Generally, the temperature of the roasting film is set at 70 At about ℃, when the paraffin section of the tissue is baked, the water between the slide and the tissue will become more tense under the instantaneous high temperature, which will cause the tissue slice to expand rapidly, and the specimen loaded on the slide will easily shift. , affecting pathological diagnosis
