AI Technical Summary
In existing technologies, the recovery of residual staining reagents after staining glass slides is inconvenient, resulting in complicated operations and waste.
A FISH staining reagent dispensing and recycling mechanism was designed, including an absorbent sponge, a filter box, and a compression component. The absorbent sponge adsorbs excess reagent, and the compression component squeezes it into the filter box for collection. Combined with a plastic box and a liquid dispensing component, the mechanism achieves efficient reagent recycling and precise dispensing.
It improves ease of operation, reduces reagent waste, lowers maintenance costs, and enhances experimental efficiency.

Abstract
Claims
1. A mechanism for dispensing and recovering a FISH staining reagent, characterized by, include: Fixed bracket; A storage tray, the top surface of which has several insertion holes for placing glass slides, the insertion holes extending to the bottom surface of the storage tray, the side surface of which has holes, and the bottom surface of which has several suction holes that are connected to the holes, the holes being connected to a vacuum pump. An absorbent sponge is attached to the bottom surface of the tray through an air suction hole and an air pump. The absorbent sponge covers several of the insertion holes to absorb excess FISH staining reagent. A filter box is mounted on the fixed bracket and located directly below the storage tray. The bottom surface of the filter box is provided with filter holes, and a collection box is provided at the bottom of the filter box. A compression assembly is connected to a fixed bracket and has a compression end that faces the filter holes inside the filter box.
2. The FISH staining reagent dispensing and recovering mechanism according to claim 1, wherein It also includes a plastic box, in which the absorbent sponge is inserted and fitted, and the plastic box is made of a thin plastic sheet.
3. The FISH staining reagent dispensing and recovering mechanism according to claim 1, wherein There is a gap between the storage tray and the filter box. The compression assembly is disposed in the gap. The compression assembly includes a rotating component, a pushing component, and a pressure plate. The rotating component is connected to the fixed bracket. The pushing component is connected to the rotating end of the rotating component. The pressure plate is connected to the protruding end of the pushing component. The pushing component and the pressure plate move into or out of the gap due to the rotation of the rotating component. When the pushing component moves into the gap, the pressure plate is directly opposite the opening of the filter box. The pressure plate compresses the absorbent sponge in the filter box through the pushing component. When the pushing component moves out of the gap, the absorbent sponge can be blown into the filter box through the air intake and the air pump.
4. The FISH staining reagent dispensing and recovering mechanism according to claim 3, wherein The rotating component includes a drive motor and a connecting arm. The drive motor is connected to the fixed bracket via a motor mount. One end of the connecting arm is connected to the output end of the drive motor, and the other end of the connecting arm is connected to the pushing component.
5. The FISH staining reagent dispensing and recovering mechanism according to claim 3, wherein The pushing component is an electric cylinder, a pneumatic cylinder, or a hydraulic cylinder.
6. The FISH staining reagent dispensing and recovering mechanism according to claim 1, wherein The inner bottom surface of the collection box is sloping, and a drain pipe connector is provided on the side of the collection box. The drain pipe connector is located on the side with the lower terrain near the inner bottom surface of the collection box.
7. The FISH staining reagent dispensing and recovering mechanism according to claim 1, wherein It also includes a liquid dispensing assembly, which further includes a feeding chamber and a liquid dispenser. The feeding chamber has a relatively sealed inner cavity. The bottom of the feeding chamber is provided with a plurality of conical liquid outlets, which correspond to a plurality of the insertion holes respectively, and the conical ends of the conical liquid outlets face downwards. The feeding chamber is provided with an opening, which is connected to the drain port of the liquid dispenser through a pipe.
8. The FISH staining reagent dispensing and recovering mechanism according to claim 7, wherein The liquid dispensing assembly also includes an extension member, the extension end of which is provided with a connecting plate, and the connecting plate is connected to the top surface of the feeding chamber plate.
9. The FISH staining reagent dispensing and recovering mechanism according to claim 8, wherein, The protruding part is an electric cylinder, pneumatic cylinder, or hydraulic cylinder; the liquid delivery device is a peristaltic pump or an electric syringe.
