Slide clamp for liquid-based specimen slide manufacture dyeing machine

Abstract

The invention relates to a slide clamp for a liquid-based specimen slide manufacture dyeing machine. The slide clamp comprises a supporting frame, a transmission unit, a clamping unit and a heating unit, wherein the lower end of the supporting frame is provided with connecting holes for connecting the external movement mechanism of the slide clamp, and the supporting frame can be driven by the external movement mechanism to carry out linear reciprocating movement; the transmission unit comprises a central shaft, a gear and an overturning stop block, wherein the central shaft is rotatably supported on the upper end of the supporting frame, the gear is fixed on one end of the central shaft, and the overturning stop block is fixed on the other end of the central shaft; the clamping unit comprises a bottom plate, a supporting sheet and an elastic element, wherein the bottom plate is fixedly supported on the central shaft and is used for placing a glass slide material, the supporting sheetis fixedly arranged on the bottom plate, one end of the elastic element is fixedly connected with to the supporting sheet, and the other end of the elastic element is elastically pressed on the glassslide material; and the heating unit is rotatably supported on the central shaft, is positioned below the bottom plate and can rotate around the central shaft to be fit to the glass slide material toheat the glass slide material. By use of the slide clamp, overturning, inclination and movement can be realized in a fully-automatic way, and a good glass slide heating effect can be guided.

Description

technical field [0001] The invention relates to the field of slide clips, in particular to a slide clip for a liquid-based specimen preparation and staining machine. Background technique [0002] At present, in medical and health clinical inspections, microscopic examination requires front-end processing such as specimen preparation and staining. Both preparation and staining of specimens need to be carried out on glass slides, and special slide holders need to be designed to hold the slides. slides, so that the slides can flow smoothly in each operation process. [0003] In the existing slide clamp structure based on the membrane method, the slides need to be loaded upside down. After the preparation is completed, the specimens are easily attached to the lower surface of the slides and fall off. Moreover, because the specimens are reversed, they cannot be stained directly on the slides. The current method is to manually remove the prepared slides, turn them over and put th...

Problems solved by technology

[0006] (1) Manual heating can be used when fixing specimens and staining. When heating, hold the glass slide under an alcohol lamp and heat it for a while. When you see steam coming out of the glass slide, leave the flame. After the steam disappears, heat again. Repeat this process for 3 to 4 times, this method has serious problems such as uncontrollable heating temperature and high risk;

[0007] (2) The air heating of the instrument can only be used in a closed environment. Some systems are equipped with an air filtration system, which will have a great impact on the air temperature, and the indirect heating of the air is slow, which is difficult to achieve when the temperature needs to be changed;

[0008] (3) Existing instruments also use pipeline indirect heating method to heat the dye solution to the required temperature, but this method can only be carried out before the dye solution is sprayed out of the pipeline, and the dye solution cannot be continuously heated to a constant temperature after the dye solution is sprayed out. The temperature loss of the dye solution during the dyeing process will directly affect the dyeing effect

And this method is only suitable for heating the staining solution, and other heating methods are required for the transfer and fixation of the specimen

[0009] (4) At present, the heater is directly attached to the glass slide to heat the design. Most of them are made of duralumin, which has the problem of insufficient protection of the heater. Especially in the dyeing process, there will be risks such as material corrosion and liquid infiltration.
