Description
Technical Field
[0001] The utility model relates to the technical field of reagent test distribution, in particular to a multi-channel distributor for reagent testing. Background Art
[0002] When testing in the laboratory, it is usually necessary to accurately distribute and use reagents according to the experimental design and requirements. The distribution amount, distribution method and distribution timing of the reagents may affect the accuracy and reliability of the test results. Therefore, before the test, the distribution plan of the reagents needs to be carefully planned and designed to ensure the smooth progress of the experiment and the accuracy of the results.
[0003] In order to overcome the above defects, the prior art 1 (publication number: CN201890764U, Chinese patent published on 2011-07-06) is a reagent dispensing device, including a stepper motor, a connecting base and an N-way valve; the stepper motor and the N-way valve are respectively fixedly arranged on the connecting base; the stepper motor and the N-way valve are fixedly connected; the N-way valve is provided with an inner core and an outer shell, and the outer shell contains N reagent sample channels; the stepper motor adopts a 360 / N degree angle setting for each step; the inner core selects a reagent sample channel according to each step. The above scheme provides a product with a reasonable structure, which can not only significantly improve the performance of the product and improve the design layout of the product, but also effectively increase the efficiency of extracting the reagent solution and improve the accuracy of the extraction; thereby overcoming the shortcomings of the existing metering components, simplifying the control of reagent distribution, facilitating instrument programming control, and facilitating subsequent troubleshooting, greatly enhancing the user's use effect and improving work efficiency.
[0004] There is also prior art 2 (publication number: CN221458184U, Chinese patent with publication date of 2024-08-02) an automated reagent rapid dispensing machine, including a base and a support plate, a No. 2 rotating shaft is rotatably connected to the top of the base, the upper end of the No. 2 rotating shaft is rotatably connected to a bottom plate, the upper end of the bottom plate is fixedly connected to a plurality of cylindrical blocks, the upper end of the bottom plate is fixedly connected to a No. 2 turntable, and the cylindrical block is installed on the outside of the No. 2 turntable, the upper end of the No. 2 turntable is fixedly connected to a plurality of cylindrical rods, and a bracket is installed above the fixed plate. By starting the motor, the motor drives the No. 1 rotating shaft to rotate, thereby driving the No. 1 turntable and the lever to rotate synchronously. When the lever rotates, it will press against the cylindrical rod and drive the cylindrical rod to rotate. When the cylindrical rod rotates, it drives the bracket to rotate, thereby driving the reagent tube to rotate. By rotating the No. 1 turntable once, the bracket is driven to rotate, so as to realize intermittent rotation of the bracket, giving the liquid outlet tube sufficient time to pour the reagent liquid into the reagent tube, thereby further improving the distribution efficiency.
[0005] Although the existing technologies 1 and 2 can perform liquid distribution operations, the inside of the distribution barrel cannot be stirred during the liquid distribution process, and the liquid inside may precipitate, resulting in uneven liquid distribution concentration.
