Abstract
Description
Technical Field
[0001] The present application relates to the field of pharmaceutical sampling, and in particular to a sampler with adjustable sampling volume. Background Art
[0002] In the production process of pharmaceutical companies, quality control is a key link to ensure the safety and effectiveness of drugs, and the sampling step is a vital part of the quality control process. Accurately and consistently obtaining representative samples is essential to ensure that the entire production batch meets the specified quality standards. In the prior art, for the sampling process of solid powdered materials, pharmaceutical factories usually use some basic manual tools such as spatulas, spoons, sampling picks, etc. for sampling. Although these methods are simple and easy to use, they have many shortcomings, especially in terms of accuracy and efficiency.
[0003] When using traditional tools such as spatulas and spoons for sampling, it is difficult to accurately control the amount of material taken out. Samplers usually need to rely on personal experience to judge the approximate quality of the materials taken. This subjective judgment method is easily affected by human factors, resulting in unrepresentative samples, which in turn affects the subsequent quality analysis results. In addition, because it is difficult to accurately obtain the required number of samples at one time, the sampling process often needs to be repeated many times to reach the sample volume required for quality testing. This repeated sampling not only wastes precious raw materials, but also greatly reduces sampling efficiency and increases production costs. Summary of the invention
[0004] The purpose of the present application is to provide a sampler with adjustable sampling volume, which can quantitatively sample inside a material and adjust the number of samples taken each time, thereby reducing labor costs.
[0005] The present application discloses a sampler with adjustable sampling volume, comprising: a sampler outer sleeve rod 1, a sampling rod 2 and a plurality of sampling accessories 3;
[0006] The sampler outer rod 1 is cylindrical, a conical head 11 is provided at the first end of the sampler outer rod 1, an opening 12 is provided at the second end of the sampler outer rod 1, and the sampling rod 2 extends into the sampler outer rod 1 along the axial direction of the sampler outer rod 1 through the opening 12;
[0007] A strip window 13 is provided on the wall of the sampler outer rod 1, and a sampling groove 21 is provided on the side wall of the sampling rod 2. The strip window 13 corresponds to the sampling groove 21. After the sampler is inserted into the sampler outer rod 1, the center of the sampling groove 21 and the center of the strip window 13 overlap in the normal direction.
[0008] The sampling accessory 3 is removably embedded in the sampling groove 21, and the sampling accessory 3 is provided with a plurality of sampling holes 31, the depth of the sampling holes 31 is less than the depth of the sampling accessory 3, the aperture, spacing and depth of the plurality of sampling holes 31 are consistent, and the sampling holes 31 are configured to accommodate powdered materials, and each of the plurality of sampling accessories 3 has an aperture, depth and number of the sampling holes 31 that is different from those of other sampling accessories 3.
[0009] In a preferred example, the sampling rod 2 is in the shape of a solid stick, and the diameter of the sampling rod 2 is 16 mm-18 mm.
[0010] In a preferred example, a hand-held portion 22 is provided at one end of the sampling rod 2, and the hand-held portion 22 is arranged at the axis of the sampling rod 2. The hand-held portion 22 is configured to assist in inserting the sampling rod 2 into the sampler outer casing rod 1 or removing the sampling rod 2 from the sampler outer casing rod 1.
[0011] In a preferred example, the length of the sampling rod 2 is 800 mm-1500 mm.
[0012] In a preferred example, the width of the strip-shaped window 13 is 6 mm-10 mm, and the length of the strip-shaped window 13 is 25 mm-35 mm.
[0013] In a preferred example, the width of the sampling groove 21 is 8 mm-15 mm, the length of the sampling groove 21 is 25 mm-35 mm, and the depth of the sampling groove 21 is 10 mm-15 mm.
[0014] In a preferred embodiment, the sampling accessory 3 is provided with three sampling holes 31 .
[0015] In a preferred example, the depth of the sampling hole 31 is 10 mm.
[0016] In a preferred example, the depth of the sampling hole 31 is 7 mm.
[0017] In a preferred example, the depth of the sampling hole 31 is 4 mm.
[0018] In the embodiment of the present application, a sampler outer rod and a sampling rod are provided, a strip window is provided on the sampler outer rod, a sampling slot is provided on the sampling rod, and the sampling slot is used to accommodate the sampling accessory. The strip window and the sampling slot correspond to each other so that the material to be sampled can fall into the sampling hole of the sampling accessory through the strip window. Since the aperture and depth of the plurality of sampling holes are consistent, the sampling amount in each sampling hole can be guaranteed to be consistent. The aperture, number of openings, and opening depth of different sampling accessories are inconsistent, and the sampling volume can be adjusted, thereby controlling the actual sampling amount. The conical head at one end of the sampler outer rod can help the sampler to be inserted into the sampled material, and the conical tip can reduce the resistance when entering the material, making the sampling process smoother.
[0019] Furthermore, the width and length of the strip window are smaller than the width and length of the sampling slot, which can prevent the sampling accessories placed in the sampling slot from falling out;
[0020] Furthermore, a hand-held portion is provided at one end of the sampling rod, which can assist the sampling personnel in inserting the sampling rod into the outer rod of the sampler or taking the sampling rod out of the outer rod of the sampler.
[0021] A large number of technical features are recorded in the specification of this application, which are distributed in various technical solutions. If all possible combinations of technical features of this application (i.e., technical solutions) are to be listed, the specification will be too long. In order to avoid this problem, the various technical features disclosed in the above-mentioned invention content of this application, the various technical features disclosed in the various embodiments and examples below, and the various technical features disclosed in the accompanying drawings can be freely combined with each other to form various new technical solutions (these technical solutions are all deemed to have been recorded in this specification), unless the combination of such technical features is technically infeasible.
