Technical Field

[0001] This utility model relates to the field of pharmaceutical testing technology, specifically to a sample processing device for pharmaceutical testing. Background Technology

[0002] In existing technologies, drugs are pulverized and mixed. The powdered tablets are then added to a mixing device to mix with a solution, and the resulting solution is the sample solution used for drug testing.

[0003] Chinese Patent CN221359562U discloses a mixing and shaking mechanism for intravenous injection drugs, relating to the field of drug mixing equipment technology.

This invention allows for adjustment of the overall protective height of the medicine bottle by sliding a second protective cover along a first protective cover, based on the height of the bottle. Tightening the fixing knob locks the first and second protective covers, facilitating the adjustment and fixing of the protective height of the medicine bottle. By adjusting the protective height according to the different heights of the medicine bottle, it provides sufficient protection while facilitating its handling.

[0004] However, in the above technical solution, the push plate is pushed back and forth, which drives the slider to slide along the slide groove. At this time, the spring is reciprocating and extending. By sliding the slider along the slide groove and guide rod, the vibration that may be generated in the vertical direction is limited, so as to avoid the push plate from vibrating in the vertical position and make the medicine bottle shake more stably in the horizontal direction. However, when the medicine bottle oscillates in the horizontal direction, the shear force and turbulence distribution are limited, and laminar flow is easily formed. Utility Model Content

[0026] Example 2

[0027] like Figures 1-4 As shown, the present invention provides a sample processing device for drug testing. Compared with Embodiment 1, this embodiment describes the detailed structure of the oscillation component. The moving component also includes a drive device 9, an output shaft 10, and rolling wheels 11. The drive device 9 is connected to the fixed base 1. The output end of the drive device 9 is connected to the output shaft 10. One end of the output shaft 10 passes through the fixed base 1 and is connected to the irregular turntable 4. The drive device 9 is a motor. Multiple rolling wheels 11 are distributed and connected to the test tube rack 3. The rolling wheels 11 are rotatably connected to the guide frame 7.

[0028] In an optional embodiment, the guide frame 7 consists of a support frame 12 and a movable frame 13. One end of the movable frame 13 is rotatably connected to the support frame 12.

[0030] Example 3

[0031] like Figures 3-5As shown, this utility model proposes a sample processing device for drug testing. Compared with Embodiment 2, this embodiment describes the detailed structure of the protective component. The protective component includes a protective plate 16, a fixed cylinder 17, an adjusting rod 18, an adjusting handle 19, and guide rods 20. The protective plate 16 is arranged parallel to the test tube rack 3, and a number of sealing gaskets corresponding to the number of test tubes are connected to the protective plate 16; the sealing gaskets are selected, but are not limited to, rubber layers; the fixed cylinder 17 is connected to the test tube rack 3, and a threaded hole is opened in the fixed cylinder 17; one end of the adjusting rod 18 is rotatably connected to the fixed cylinder 17, and the other end of the adjusting rod 18 is connected to the adjusting handle 19. The adjusting rod 18 is rotatably connected to the protective plate 16; four guide rods 20 are distributed, and the guide rods 20 are connected to the test tube rack 3. The guide rods 20 are slidably connected to the through holes opened in the protective plate 16.

[0032] In summary, when using this utility model, the operator inserts the test tube containing the solution and medicine into the limiting tube 22. The second elastic element 24 pushes the clamping plate 23 to restrict the test tube. Then, the adjusting rod 18 is inserted into the fixed cylinder 17, and the guide rod 20 is aligned with the through hole on the protective plate 16. When the adjusting handle 19 is rotated, the adjusting rod 18 rotates and gradually enters the fixed cylinder 17. At this time, the protective plate 16 is moved closer to the test tube rack 3, thus restricting the vertical movement of the test tube. When the sample is shaken, the telescopic device 8 is activated. The telescopic end of the telescopic device 8 extends and drives the movable frame 13 to rotate with its hinge point as the center, thereby changing the guide frame 7 from a horizontal state at both ends to a horizontal state at one end. The horizontal end is tilted to accelerate the mixing of the solution and medicine and avoid stratification. The drive device 9 is activated, and its output end drives the irregular turntable 4 to rotate. The irregular turntable 4 contacts the roller 6 on one side of the stop block 5. The contact between the irregular turntable 4 and the roller 6 allows it to push the test tube rack 3 to move horizontally. The test tube rack 3 slides in the sliding groove 14 on the guide frame 7 through the roller 11. One end of the test tube rack 3 is guided by the movable frame 13 and gradually tilts. When it moves to the predetermined position, the test tube rack 3 will contact the first elastic element 15. The first elastic element 15 is compressed. As the pressure of the irregular turntable 4 on it disappears, the first elastic element 15 rebounds and pushes the test tube rack 3 to rebound. This process is repeated to mix the medicine sample.

[0033] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
