[0021] ​To make the technical means, creative features, and achieved objectives and effects of this utility model easier to understand, the present utility model is further described below with reference to specific embodiments and accompanying drawings. However, the following embodiments are merely preferred embodiments of this utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described in the implementation plan without creative effort are all within the protection scope of this utility model.

[0022] The specific embodiments of this utility model are described below with reference to the accompanying drawings.

[0023] Example 1

[0024] like Figures 1-3 As shown, a staining needle assembly for a slide preparation and staining integrated machine includes multiple storage cylinders 3. The bottom of the storage cylinder 3 is fixedly connected to one end of a flexible tube 4 and communicates with it. The other end of the flexible tube 4 passes through a support base 5. Multiple staining components 6 are provided at the bottom of the support base 5. The flexible tube 4 and the staining components 6 are connected one-to-one.

[0025] A pressure block 2 is provided inside the storage cylinder 3, and the pressure block 2 slides in fit with the inner wall of the storage cylinder 3. A handle 1 is provided above the pressure block 2, and the handle 1 is fixedly connected to the top of the pressure block 2. A bracket 8 is provided on the support base 5, and the bracket 8 is fixedly connected to the support base 5. Multiple connecting screws 7 are threaded on the bracket 8.

[0026] In use, different staining solutions are placed into different storage cylinders 3, and then the pressure block 2 is inserted into the storage cylinder 3. Under the action of gravity, the pressure block 2 presses the staining solution into the hose 4, and then discharges it through the staining assembly 6 to stain the specimen.

[0027] Example 2

[0028] like Figures 1-3 As shown, while all other parts are the same as in Embodiment 1, the difference between this embodiment and Embodiment 1 is that: the dyeing assembly 6 includes an outer tube 14, which penetrates the bottom of the support base 5 and is fixedly connected to the support base 5. The top of the outer tube 14 is fixedly connected to and communicates with the flexible tube 4. A first limiting ring 15 is fixedly installed inside the outer tube 14, and the bottom of the first limiting ring 15 is fixedly connected to the upper end of the spring 16. The lower end of the spring 16 is fixedly connected to the top of the sealing disc 17. Several through holes 9 are opened on the edge of the sealing disc 17. An inner tube 10 is provided below the sealing disc 17, and the top of the inner tube 10 is located inside the outer tube 14. The inner tube 10 and the outer tube 14 are threaded together. A silicone ring 12 is fixedly installed on the top of the inner tube 10. A second limiting ring 13 is sleeved on the outside of the inner tube 10 and is fixedly connected to the inner tube 10. The bottom of the inner tube 10 is fixedly connected to and communicates with the top of the needle tube 11.

[0029] Before use, rotate the inner tube 10 so that the silicone ring 12 on the inner tube 10 presses against the sealing disc 17, thereby sealing the through hole 9 at the edge of the sealing disc 17 with the silicone ring 12.

[0030] After the dyeing liquid is pressed into the hose 4 under the action of gravity, the dyeing liquid enters the outer tube 14 above the sealing disc 17, and since the through hole 9 on the sealing disc 17 is closed, the dyeing liquid cannot enter below the sealing disc 17.

[0031] When it is needed to use which dyeing liquid, the inner tube 10 on the side where the dyeing liquid is located is reversely rotated, so that the silica gel ring 12 on the inner tube 10 is away from the sealing disc 17, at this time the dyeing liquid in the outer tube 14 flows into the inner tube 10 through the through hole 9, and then flows out through the needle tube 11 to dye the sample.

[0032] The basic principle, main features and advantages of the present application are shown and described above. It should be understood by those skilled in the art that the present application is not limited by the above embodiments, and the above embodiments and descriptions in the specification are only preferred examples of the present application and are not intended to limit the present application. Without departing from the spirit and scope of the present application, various changes and improvements can be made to the present application, and these changes and improvements all fall within the scope of the present application. The scope of protection of the present application is defined by the appended claims and their equivalents.
