Description

Technical Field

[0001] This utility model relates to the field of measurement and testing technology, specifically to a glass slide staining device. Background Technology

[0002] In the automated testing process of medical devices, in order to effectively observe cells and tissues, the blood film on the slide needs to be automatically stained, rinsed, and dried before microscopic observation. Typically, cells or tissues are formed into a thin film on a glass slide (referred to as a slide). The slide containing the cell or tissue film is then stained with staining solutions or buffer solutions (i.e., different components of the cells or tissues in the film are stained with different colors). After staining, the stained slide is rinsed with washing water to remove excess liquid, and then dried. Only after drying can the slide be placed under a microscope for observation.

[0003] During the process, there are problems such as difficulty in replacing the dyeing tank, poor rinsing effect, and low processing efficiency. Summary of the Invention

[0004] This invention addresses the problems of difficult staining tank replacement, poor rinsing effect, and low processing efficiency by providing a slide staining device. The staining tank is secured by magnets for easy replacement. Both the staining tank and rinsing tank have overflow ports to promptly drain excess dye when too much reagent is added, preventing leakage. The rinsing tank outlet surrounds the slide, ensuring that all surfaces are rinsed to completely remove residual dye. Two slide transfer assemblies improve slide transport efficiency, thereby increasing the throughput of blood smear staining. The drying tank allows airflow to completely cover the slide surface, reducing drying time. Dye addition is done using a dye injection needle, saving on some liquid path steps.

[0036] The staining tank assembly 1 includes a staining tank 11, which comprises a base 111, magnets 112, a magnetic fixing plate 113, a staining tank body 114, and an overflow port 115. The staining tank body 114 is fixed to the magnetic fixing plate 113. Two magnets 112 are fixed on the base 111, allowing the staining tank body 114 to be fixed in place by the attraction of the magnets 112 and easily removed. The staining tank body 114 includes a connected slide staining tank 1141 and a staining agent filling tank 1142. The overflow port 115 is connected to one side of the staining agent filling tank 1142. Each staining tank 11 has 10 individual bodies 114, and each staining tank body 114 is not interconnected. Staining agent is added to one staining tank body 114, and a slide A is placed in it for staining. Figure 4 , 5 As shown.

The rinsing tank body 21 has two pipe connection ports (waste liquid outlet 25 and rinsing liquid outlet 26). Cleaning liquid is added through the lower connection port (rinsing liquid outlet 26), flows through the internal interlayer gap (rinsing liquid channel 23) to the top outlet, flows downwards over the surface of slide A, and flows out to the other connection port (waste liquid outlet 25) to be discharged into the waste liquid, achieving the purpose of rinsing residual dye on the surface of slide A. Figure 6 As shown.

[0038] The drying chamber assembly 3 includes a drying chamber 31, a flow guiding block 32, a heating module 33, and a fan 34. After the slide A is placed in the drying chamber 31, hot air can be delivered to the surface of the slide A through the fan 34 and the heating module 33, thereby achieving the effect of drying the blood film on the surface of the slide A. Figure 7 , 8 As shown, heating module 33 is a PTC heater.

The first slide transfer assembly 7 can clamp slide A, move it horizontally and vertically, and can remove slide A from one slot and place it in another slot. The second slide transfer assembly 8 can clamp slide A, move it horizontally, vertically, and longitudinally, and can remove slide A from one slot and place it in another slot, and can also transfer slide A to the slide exit device. The dye dispensing assembly 10 can move the dispensing needle 1A above any staining tank body 114 and can extend into the staining tank body 114 to add dye or suck up dye. The transfer assembly fixing plate and guide rail 6 and the dye dispensing assembly fixing plate and guide rail 9 are fixed on two support columns 4 and 5. The dye dispensing assembly 10, the first slide transfer assembly 7, and the second slide transfer assembly 8 are fixed on the guide rails and can move horizontally. Both the dyeing tank body 114 and the rinsing tank body 21 are equipped with overflow ports, which will discharge the excess dye solution in time when too much reagent is added, thus preventing dye solution leakage.

[0040] In this embodiment, there are 4 sets of staining tank assemblies 1, each set including 10 staining tanks 11. The staining tank assembly 1 is made of resin and has a total height of 84mm. The staining agent dispensing tank 1142 has a height of 58mm and a width of 26mm. The first slide transfer assembly 7 and the second slide transfer assembly 8 both have a stroke of 400mm. The first slide transfer assembly 7 moves between the 1st to 3rd staining tank assemblies 1, allowing slide A to enter different staining tank assemblies 1 for staining in sequence. The second slide transfer assembly 8 moves above the 4th staining tank assembly 1, the rinsing tank assembly 2, and the drying tank assembly 3, and transfers slide A to the drying tank assembly 3 of the slide exit device. The stroke of the staining agent dispensing assembly 10 is 300mm, and the length of the dispensing needle 1A is 70mm.
