Slide holder for liquid-based specimen preparation and staining machine

Abstract

The invention relates to a glass slide holder of a liquid-based specimen preparation and dyeing machine, comprising: a supporting frame, the lower end of which is provided with a connection hole connected to an external movement mechanism of the slide holder, which can be driven by the external movement mechanism to perform linear reciprocating motion; a transmission unit, It includes a central shaft rotatably supported on the upper end of the support frame, a gear fixed at one end of the central shaft, and a flip block fixed at the other end of the central shaft; a clamping unit includes a fixed support on the central shaft On the bottom plate for placing the glass slide material, the support piece fixedly arranged on the bottom plate, and one end is fixedly connected to the support piece, and the other end is elastically pressed on the glass slide material; the heating unit can be It is rotatably supported on the central axis, located under the bottom plate, and can rotate around the central axis until it fits on the glass slide material and heats the glass slide material. The slide holder of the present invention can realize turning, tilting and moving fully automatically, and can ensure a good heating effect on slide slides.

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.
