[0006] The purpose of this invention is to provide a sampling device for solid dosage forms, which solves the problem that existing sampling devices lack an effective discharge structure, resulting in inconvenience in transferring materials after sampling.

[0029] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with the illustrations and specific embodiments.

[0030] like Figures 1 to 5As shown, this utility model proposes a sampling device for solid dosage forms, including a sampling plate 10 with at least two sampling planes 11, each sampling plane 11 having multiple sampling slots 12 for accommodating solid dosage forms; a positioning plate 20 with stepped positioning elements 21, the positioning plate 20 and the sampling plate 10 working together to form a discharge channel for accommodating solid dosage forms; the stepped positioning elements 21 having discharge notches 22 communicating with the discharge channel, allowing solid dosage forms in the discharge channel to be discharged outwards through the discharge notches 22. The stepped positioning elements 21 refer to positioning structures with height differences, forming a closed discharge channel through the stepped drop. The discharge channel refers to the space enclosed by the positioning plate 20 and the sampling plate 10, used for temporarily storing solid dosage forms to be discharged. The sampling slots 12 refer to recessed dosage form accommodating structures.

[0031] In use, the operator can select a specific sampling plane 11 as needed, insert the sampling plate 10 into the solid dosage form, and each solid dosage form falls into the corresponding sampling slot 12. The positioning plate 20 is precisely aligned with the sampling plate 10 through the stepped positioning member 21 to form a discharge channel. When the positioning plate 20 and the sampling plate 10 are flipped, the solid dosage form falls into the discharge channel. Then, the solid dosage form moves along the discharge channel under the action of gravity and is finally discharged through the discharge notch 22.

[0032] like Figure 3 As shown, in some embodiments, one end of the sampling plate 10 has an inclined surface 13, which facilitates the insertion of the sampling plate 10 into the solid dosage form. The inclined surface 13 refers to the inclined structure at the front end of the sampling plate 10, specifically an inclined structure of 30 to 45 degrees, which provides effective guidance while maintaining structural strength. The length of the inclined surface 13 can be 10%-15% of the total length of the sampling plate 10.

[0033] When in use, the operator pushes the sampling plate 10. After the inclined surface 13 comes into contact with the solid dosage form, it generates a component force. The vertical component force causes the sampling plate 10 to press down continuously. As the sampling plate 10 goes deeper, the inclined surface 13 continuously guides the material to stratify, reducing the resistance encountered when the sampling plate 10 is inserted into the solid dosage form.

[0034] like Figure 2 As shown, in some embodiments, the sampling plate 10 has a gripping portion 14, one end of which is integrally connected to the sampling plate 10, and the other end of which extends outward toward the sampling plate 10. In use, the operator inserts the sampling plate 10 into the solid dosage form using the gripping portion 14. The gripping portion 14 refers to a gripping part that forms a continuous structure with the main body of the sampling plate 10, providing a holding fulcrum during operation. Specifically, it can be integrally connected using a molding process, thereby eliminating the risk of component loosening and enhancing structural stability.

[0035] like Figure 2 As shown, in some embodiments, two sampling planes 11 are arranged parallel to each other, one sampling plane 11 having 50 sampling slots 12 and the other sampling plane 11 having 20 sampling slots 12. A sampling plane 11 refers to a planar structure used to hold solid dosage forms, the surface of which has regularly arranged grooves to accommodate the dosage form. The different number of sampling slots 12 refers to setting different numbers of grooves on different planes; for example, one plane may have 50 grooves for large-scale sampling, while the other plane may have 20 grooves for small-scale rapid testing.

[0036] In use, when large-scale testing is required, the operator inserts the flat plate with 50 sampling slots 12 into the formulation pile, and the formulation fills all the slots under gravity. When rapid sampling is required, the sampling plate 10 is flipped so that the flat plate with 20 sampling slots 12 contacts the formulation, enabling small sample collection. Different numbers of sampling slots 12 are integrated on the upper and lower surfaces of the sampling plate 10, allowing selection of the sampling quantity according to testing needs, while reducing manual counting.

[0037] like Figure 5 As shown, in some embodiments, the diameter of the upper end face of the sampling groove 12 is larger than the diameter of the lower end face of the sampling groove 12, which facilitates the falling of solid dosage forms into the sampling groove 12. The upper end face diameter being larger than the lower end face diameter means that the lateral dimension at the inlet of the sampling groove 12 is larger than the lateral dimension at the outlet, which can be achieved using a funnel-shaped gradient structure. This structure increases the tolerance space when the solid dosage form contacts the sample by expanding the inlet cross-sectional area, while simultaneously creating a guiding constraint through the contraction of the outlet cross-sectional area.

[0038] In use, when the solid dosage form contacts the sampling slot 12, the larger diameter of the upper end face allows for a certain positional deviation of the dosage form during the initial falling phase. At this time, after the edge of the dosage form contacts the slot opening, it slides towards the center along the funnel-shaped sidewall under the action of gravity and is eventually guided into the sampling slot 12. As the dosage form continues to fall, the smaller diameter of the lower end face restricts its lateral displacement, preventing the dosage form from tilting or getting stuck due to the excessive width of the slot, thereby ensuring that the dosage form completes the falling process along the predetermined path.

[0039] like Figure 2 As shown, in some embodiments, multiple sampling slots 12 are arranged at equal intervals on the sampling plane 11. Equal interval arrangement means that the straight-line distance between the center points of adjacent sampling slots 12 remains equal, which can be achieved using a matrix layout. This arrangement maintains a uniform spacing between the sampling slots 12, avoiding excessively high or low sampling density in local areas.

[0040] like Figure 5As shown, in some embodiments, the height of the sampling groove 12 is one-third of the height of the sampling plate 10. The height of the sampling groove 12 refers to the maximum extension dimension of the sampling groove 12 along the thickness direction of the sampling plate 10, and the depth of the groove is limited to one-third of the overall thickness of the sampling plate 10 to ensure that the main structure of the sampling plate 10 maintains sufficient rigidity.

[0041] like Figure 4 As shown, in some embodiments, the positioning plate 20 has a gripping portion 23, one end of which is integrally connected to the positioning plate 20, and the other end of which extends outward toward the positioning plate 20. The gripping portion 23 refers to the extended structure connected to the positioning plate 20, and can be formed into an integral structure with the positioning plate 20 by injection molding. The gripping portion 23 is used to provide a fulcrum for the operator to apply force.

[0042] In use, the staff attaches the positioning plate 20 to the sampling plate 10 by holding part 23. The side of the sampling plate 10 with solid preparation is attached to the positioning part 212 of the stepped positioning part 21. Then, the positioning plate 20 and the sampling plate 10 are flipped together. The solid preparation falls into the discharge trough under the action of gravity and is discharged outward through the discharge notch 22.

[0043] like Figure 4 As shown, in some embodiments, the height of the stepped positioning member 21 is greater than the height of the sampling plate 10. The positioning part 211 of the stepped positioning member 21 adopts a vertically extending plate-like structure, and the positioning part 212 is set as a horizontally extending limiting flange, which contacts the upper surface of the sampling plate 10 to form a sealing surface.

[0044] like Figure 4 As shown, in some embodiments, the stepped positioning member 21 includes a first positioning part 211 and a second positioning part 212. One end of the first positioning part 211 is integrally connected to the positioning plate 20, and the other end of the second positioning part 212 extends toward the height direction of the positioning plate 20. One end of the second positioning part 212 is connected to the first positioning part 211, and the other end of the second positioning part 212 extends toward the interior of the positioning plate 20. The stepped positioning member 21 has a positioning notch for accommodating the gripping part 14.

[0045] Among them, positioning part 1 211 refers to the support structure directly connected to the main body of positioning plate 20, and can be formed into an integral structure with positioning plate 20 by injection molding process. Positioning part 212 refers to the limiting structure extending from positioning part 1 211. When sampling plate 10 and positioning plate 20 are engaged, positioning part 1 211 is used to constrain and limit sampling plate 10 in the horizontal direction, and positioning part 212 is used to constrain and limit sampling plate 10 in the vertical direction.

[0046] Preferably, the sampling plate 10 and the positioning plate 20 are components made of a transparent material. Specifically, they can be made of acrylic material. This material allows operators to directly observe the filling status of the solid preparation in the sampling tank 12 and the discharge process of the discharge channel.

[0047] The usage process and principle of this utility model are as follows: The operator selects the sampling plane 11 according to the testing requirements. If large-scale testing is required, a plane with fifty sampling slots 12 is prepared to be used; if rapid sampling is required, a plane with twenty sampling slots 12 is prepared to be used.

[0048] Sampling Stage: Large-scale sampling: The operator uses the gripper 14 to insert the flat surface of the sampling plate 10 with fifty sampling slots 12 into the solid dosage form. The solid dosage form falls into the corresponding sampling slot 12 under gravity. Small-batch rapid sampling: When rapid sampling is required, the sampling plate 10 is flipped so that the flat surface with twenty sampling slots 12 contacts the dosage form. Similarly, the inclined surface 13 guides the material to stratify, achieving small sample collection.

[0049] Stage 20 of docking positioning plate: Next, the operator uses the gripping part 23 to attach the positioning plate 20 to the sampling plate 10, so that the side of the sampling plate 10 with solid preparation is attached to the positioning part 212 of the stepped positioning member 21, together forming a discharge channel for containing solid preparation.

[0050] Discharge stage: Then, the positioning plate 20 and the sampling plate 10 are flipped together. The solid preparation falls into the discharge channel under the action of gravity. Then, the solid preparation moves along the discharge channel and is finally discharged outward through the discharge notch 22, completing the sampling process.

[0051] In practical applications, the sampling device proposed in this application is suitable for sampling Etrasimod (trade name Vilsipity) solid dosage forms. The sampling tank is designed for the size of Etrasimod arginine tablets, and the closed discharge channel design avoids the scattering and contamination of Etrasimod arginine tablets during sampling and discharge, thus ensuring the accuracy of sampling.
