Description

Technical Field

[0001] This utility model belongs to the field of IVD equipment technology, specifically relating to a reagent shaking device for automated IVD equipment. Background Technology

[0002] Automated IVD (in vitro diagnostic) equipment refers to devices that improve diagnostic efficiency and accuracy through automation in the in vitro diagnostic process. Automated IVD equipment can automatically complete functions such as sample loading, centrifugation, decapping, testing, storage, disposal, retesting, and classification. These automated processes significantly improve production efficiency and reduce human error.

[0003] However, for some testing items, some reagents need to be shaken regularly and stored at low temperatures. Otherwise, precipitation may occur during the test, affecting the final experimental results. Existing automated IVD equipment processes a large number of samples at a time, and the reagents remain for a long time. The reagents with poor stability may affect the test results. Therefore, it is necessary to design a reagent shaking device suitable for automated IVD equipment. Summary of the Invention

[0004] The purpose of this invention is to provide a reagent mixing device that can be used in automated IVD equipment, automatically mixing some reagents in the automated IVD equipment and storing the reagents at low temperatures.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] The first aspect of this utility model provides a reagent mixing device for automated IVD equipment, the reagent mixing device comprising:

[0007] A base having a reagent receiving cavity, wherein the reagent receiving cavity has a slot extending along the front-back direction of the base, and multiple slots are arranged sequentially along the left-right direction of the base.

[0008] A reagent rack is detachably mounted in the slot. The rear end of the reagent rack is provided with a first reagent compartment and a platform located below the first reagent compartment. The first reagent compartment is open at both the top and bottom.

[0009] A reagent bottle, comprising a first reagent bottle, which is rotatably inserted into the first reagent compartment about its own axis and placed on the platform, wherein the lower end of the first reagent bottle is provided with a gear;

[0010] A drive motor is fixedly mounted on the base.

[0011] The transmission assembly includes an eccentric wheel and a rack. The center of the lower surface of the eccentric wheel is fixedly connected to the rotational output shaft of the drive motor. The upper surface of the eccentric wheel is provided with an eccentric shaft. The rack extends along the left-right direction of the base. One end of the rack is provided with a first slot extending along the front-back direction of the base. The eccentric shaft is movably inserted into the first slot. The other end of the rack is provided with a second slot extending parallel to the left-right direction of the base. A fixing member fixedly connected to the base is inserted into the second slot. The rack meshes with a gear of the first reagent bottle.

[0012] The temperature control component includes a temperature sensor disposed on the reagent containing cavity, a cooling fan and a refrigeration module disposed at the bottom of the base, the refrigeration module including a refrigeration device, and the temperature sensor, the cooling fan and the refrigeration device being electrically connected to each other.

[0013] In this invention, when the drive motor drives the eccentric wheel to rotate, it drives the rack to move. Under the limiting action of the first and second slots, the rack moves in a reciprocating linear motion in the left and right direction. Under the cooperation of the gear and rack at its bottom, the first reagent bottle moves in a reciprocating rotation in the clockwise and counterclockwise directions, thereby shaking the reagent in the first reagent bottle evenly.

[0014] In this invention, the temperature sensor can monitor the temperature of the reagent container cavity and transmit the signal to the cooling module and the cooling fan to achieve temperature control of the reagent container cavity. The cooling fan can dissipate the heat generated during the operation of the cooling system to prevent heat accumulation.

[0015] In this embodiment of the utility model, the drive motor is fixedly disposed on one side of the rear part of the base, and the left and right sides of the rear part of the base are respectively provided with a first limiting frame and a second limiting frame. The rack passes through the first limiting frame and the second limiting frame to further restrict the movement direction of the rack and improve the running stability.

[0016] Furthermore, the first limiting frame is located on the right side of the rear part of the base, near the eccentric wheel. The second limiting frame is located on the left side of the rear part of the base, and the fixing member inserted into the second strip groove is a bolt fixedly connected to the second limiting frame.

[0017] In this embodiment of the invention, the rotation output shaft of the drive motor extends along the vertical direction of the base, and the eccentric shaft extends upward from the upper surface of the eccentric wheel.

[0018] In this embodiment of the invention, the axis of the gear coincides with the axis of the first reagent bottle, and the tooth groove of the rack is located on the front side of the rack.

[0019] In this embodiment of the utility model, the reagent rack is provided with a snap-fit ​​component at the rear end, and the base is provided with a baffle at the rear end, with a row of snap-fit ​​holes on the baffle that can be connected to the snap-fit ​​component.

[0020] In this embodiment of the invention, multiple second reagent compartments for placing reagent bottles are sequentially formed along the front-back direction of the reagent rack. The upper end of each second reagent compartment is open, and the lower end is closed. Each reagent bottle also includes multiple second reagent bottles that match the second reagent compartments. The number of reagent racks is one or more. This invention only requires shaking the reagents in the first reagent bottle; other reagents that do not require shaking can be stored in the second reagent bottles. Shaking the first reagent bottle does not affect other reagent bottles, and the presence of other reagent bottles does not affect the rotation of the first reagent bottle. This design results in low energy consumption and good stability.

[0021] In this embodiment of the invention, the front end of the reagent rack is provided with a gripping part, which facilitates inserting the reagent rack into the slot and removing the reagent rack from the slot.

[0022] The second aspect of this utility model also provides an IVD device, which includes the above-mentioned reagent shaking device.

[0023] In this embodiment of the invention, the IVD device further includes a robotic arm for automatic sampling and a control system for controlling the operation of the robotic arm.

[0024] Due to the application of the above technical solution, this utility model has the following advantages:

[0025] This invention relates to a reagent mixing device for automated IVD equipment. It can automatically mix only a portion of unstable reagents, and can simultaneously mix multiple reagents prone to precipitation, ensuring that precipitation does not affect the normal operation of the instrument. Furthermore, this reagent mixing device for automated IVD equipment can monitor and control the temperature in the reagent compartment, allowing the IVD equipment to store reagents under low-temperature conditions and extending their shelf life.
