Description

Technical Field

[0001] This utility model relates to the field of automated analysis technology, and in particular to an integrated sample reagent tray structure. Background Technology

[0002] Sample reagent trays are typically designed as rotating discs with multiple stations for placing sample vials containing the samples to be tested and reagent vials required for the reaction.

[0003] The reagents on the sample reagent tray are very sensitive to the environment and need to be properly protected to prevent the entry of external contaminants such as dust and debris, reduce reagent volatilization, and ensure their stability and accuracy of test results within their shelf life. For this reason, the sample reagent tray is usually equipped with a protective shell. However, most existing protective shells only serve a simple dustproof function, and there is a large gap between the protective shell and the cover plate used to seal the opening, resulting in poor sealing performance. Especially during storage or non-working periods, it cannot effectively prevent air circulation, which can easily lead to reagents being exposed to the air for a long time, causing them to volatilize, oxidize, or become contaminated. Utility Model Content

[0004] The purpose of this invention is to design an integrated sample and reagent tray structure that is compact, cost-controllable, and can simultaneously achieve differentiated temperature control between the reagent area and the sample area.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an integrated sample reagent tray structure, including a base plate, an operating tray fixedly installed at the bottom of the base plate, a turntable fixedly installed on the output shaft of the operating tray, the turntable dividing the sample area into an inner ring and a reagent area into an outer ring, the sample area having a plurality of sample positions, the reagent area having a plurality of reagent positions, and a protective shell installed on the top of the base plate above the turntable. The top of the inner cavity of the protective shell is provided with an insertion hole, and a reset spring is installed in the groove on the top of the turntable. A lifting plate fixed on the top of the reset spring is provided with an insertion block. The lifting plate is slidably connected to the inner wall of the groove. When the operating plate drives the turntable to rotate to the preset work position, the insertion block is inserted into the insertion hole.

[0006] As a further description of the above technical solution: the top of the turntable is provided with an annular partition plate, which is used to separate the sample area of ​​the inner ring and the reagent area of ​​the outer ring.

[0007] As a further description of the above technical solution: the insert is a hemispherical or conical structure with an arc surface.

[0008] As a further description of the above technical solution: the edge of the lifting plate is provided with a sealing ring, and when the lifting plate is pushed upward, the sealing ring fits against the inner wall of the protective shell.

[0009] As a further description of the above technical solution: the top of the lifting plate is provided with several placement holes for placing reaction cups.

[0010] As a further description of the above technical solution: the sample position is used to place the sample bottle.

[0011] As a further description of the above technical solution: the reagent position is used to place a reagent bottle.

[0012] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are: A locking mechanism consisting of a return spring, a lifting plate, and an insert block is adopted. When the turntable rotates to the preset position, the insert block is automatically inserted into the insertion hole of the protective shell under the action of the spring force, thereby fixing the rotation position of the turntable and ensuring that the turntable remains stationary during storage. Furthermore, when the lifting plate is pushed upward by the spring, the sealing ring on its edge will fit tightly against the inner wall of the protective shell, thereby forming a sealed space between the turntable and the protective shell.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figures 1-3This utility model provides a technical solution: an integrated sample reagent tray structure, in which a turntable 13 is rotatably mounted on the top of a base plate 10, and the rotation axis of the turntable 13 passes through the base plate 10 and is fixed with an operation disk 19. By rotating the operation disk 19, the turntable 13 can be controlled to rotate.

[0017] A protective shell 12 is fixedly installed on the top of the base plate 10. The protective shell 12 protects the internal components such as the turntable 13, sample bottle 14, and reagent bottle 15, preventing external pollutants such as dust and debris from entering.

[0018] The turntable 13 is disc-shaped and divided into two functional areas: an inner sample area and an outer reagent area. The sample area has several sample positions 131 for placing sample bottles 14, and the reagent area has several reagent positions 132 for placing reagent bottles 15. The sample bottles 14 and reagent bottles 15 are respectively loaded with the sample to be tested and the required reagents.

[0019] The top of the turntable 13 is provided with a ring-shaped partition plate 133, which separates the sample area in the inner ring from the reagent area in the outer ring.

[0020] The top of the inner cavity of the protective shell 12 has multiple insertion holes, and the top of the turntable 13 has a rectangular groove. Several return springs 17 are installed in the groove. The tops of all the return springs 17 are fixedly supported by a lifting plate 18. The outer diameter of the lifting plate 18 is precisely matched with the inner diameter of the groove. The lifting plate 18 slides up and down along the inner wall of the groove.

[0021] At least one insertion block 16 is provided on the top of the lifting plate 18 and at the corresponding insertion hole position of the protective shell 12. The insertion block 16 is preferably hemispherical or conical with an arc surface. When the operating disk 19 drives the turntable 13 to rotate to a preset specific work position, the insertion block 16 on the lifting plate 18 is aligned with the insertion hole on the top of the protective shell 12. Under the elastic force of the return spring 17, the lifting plate 18 is pushed upward, so that a part of the insertion block 16 extends into the insertion hole. At this time, the edge of the lifting plate 18 is tightly fitted with the inner wall of the protective shell 12 through the provided sealing ring (not shown), forming a sealed space.

[0022] The operating panel 19 can drive the turntable 13 to rotate. Since the insert block 16 is designed as a hemispherical shape, its smooth curved surface can smoothly disengage from the insertion hole under the action of rotational shear force, and compress the return spring 17, causing the lifting plate 18 to descend, thereby releasing the positioning and sealing state, allowing the turntable 13 to rotate freely to the next work station.

[0023] On the top of the lifting plate 18, there are also several placement holes for placing reaction cups 11. The reaction cups 11 are containers for mixing and reacting samples and reagents. When the turntable 13 rotates to the appropriate position, the external sample addition system, such as the sample addition needle, will draw liquid from the sample bottle 14 and reagent bottle 15 through the opening at the top of the protective shell 12 and inject it into the reaction cup 11 at the designated position for reaction.

[0024] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
