Sampling equipment for traditional Chinese medicine ingredient inspection

Abstract

The utility model relates to the technical field of traditional Chinese medicine sampling, in particular to sampling equipment for traditional Chinese medicine ingredient inspection. Comprising a sampling barrel and a sampling tube, the sampling tube is communicated with an inner cavity of the sampling tube, a filter plate is arranged in the sampling tube, and the negative pressure system is used for providing negative pressure for the inner cavity of the sampling tube so as to suck a solution into the sampling tube. When the traditional Chinese medicine components are inspected and sampled, the negative pressure system is started to generate negative pressure in the inner cavity of the sampling barrel. As the sampling tube is communicated with the inner cavity of the sampling tube, the traditional Chinese medicine solution is sucked into the sampling tube. When a solution passes through the filter plate in the sampling tube, small-particle substances in the solution are blocked, and the filtered solution smoothly enters the sampling barrel, so that accurate sampling is completed. And through the arrangement of the filter plate, small-particle substances are effectively prevented from entering the sampling barrel, and the purity of a taken sample is ensured, so that the accuracy of a detection result is improved, and the actual condition of components in a traditional Chinese medicine solution can be truly reflected. The device can be widely applied to the technical field of traditional Chinese medicine sampling.

Description

Technical Field

[0001] This utility model relates to the field of traditional Chinese medicine sampling technology, specifically, to a sampling device for testing the components of traditional Chinese medicine. Background Technology

[0002] With the widespread application of traditional Chinese medicine (TCM) in the healthcare field, the accurate testing of TCM components has become increasingly important. In the process of testing TCM components, it is often necessary to decoct the herbs into a solution to detect the content and properties of certain soluble components.

[0003] Because the solution obtained after decocting traditional Chinese medicine is usually not completely homogeneous, it needs to be stirred during sampling to ensure representativeness. However, the solution contains a large number of small particles, which are very likely to enter the sampler along with the solution during sampling, thus affecting the accuracy and representativeness of the sample. This can not only lead to biased test results that fail to accurately reflect the actual composition of the traditional Chinese medicine solution, but may also delay the assessment of the quality and efficacy of the traditional Chinese medicine due to inaccurate sampling.

[0004] Therefore, in order to improve the accuracy and reliability of the testing of Chinese medicine components, there is an urgent need for a sampling device that can effectively prevent small particles from entering and achieve precise sampling. Utility Model Content

[0005] In view of the problems existing in the prior art, this utility model proposes a sampling device for the testing of Chinese medicine components.

[0006] To solve the above-mentioned technical problems, the present invention provides a solution through the following technical method:

[0007] A sampling device for testing components of traditional Chinese medicine includes a sampling cylinder and a sampling tube; the sampling cylinder is connected to the inner cavity of the sampling tube, a filter plate is provided inside the sampling tube, and a negative pressure system is also included to provide negative pressure to the inner cavity of the sampling cylinder so as to draw the solution into the sampling cylinder.

[0008] When sampling for testing the components of traditional Chinese medicine (TCM), the negative pressure system is activated to create negative pressure inside the sampling cylinder. Since the sampling cylinder and sampling tube are connected, the TCM solution is drawn into the sampling tube and then into the sampling cylinder under the negative pressure. As the solution passes through the filter plate inside the sampling tube, small particulate matter is blocked, while the filtered solution smoothly enters the sampling cylinder, completing accurate sampling. The filter plate effectively prevents small particulate matter from entering the sampling cylinder, ensuring the purity of the sample and thus improving the accuracy of the test results, accurately reflecting the actual composition of the TCM solution.

[0009] Preferably, the negative pressure system includes a negative pressure cylinder that can be screwed into the sampling cylinder. The outer wall of the negative pressure cylinder is provided with external threads, and the inner wall of the sampling cylinder is provided with internal threads that mate with the outer wall. The negative pressure cylinder is open at both ends, and a piston and a pull rod for controlling the piston's up and down movement are provided inside the negative pressure cylinder.

[0010] When negative pressure is required, the negative pressure cylinder is screwed into the sampling cylinder via a thread. A lever controls the piston inside the negative pressure cylinder to move upwards, increasing the space within the cylinder and decreasing the pressure, thus creating negative pressure inside the sampling cylinder and drawing the herbal solution into it. The threaded connection allows the negative pressure cylinder to be disassembled, facilitating cleaning and disinfection of internal components, preventing cross-contamination, and ensuring the accuracy and reliability of each sampling.

[0011] As a preferred option, it also includes a sealing plate, one end of which is provided with a sealing post, which can be screwed into the sampling tube to seal the sampling tube.

[0012] After sampling, screw the sealing column into the sampling tube to ensure a tight seal between the sealing plate and the tube opening, thus sealing the tube. Then, unscrew the negative pressure cylinder and pour the solution from its opening out. This effectively prevents contamination from herbal particles adhering to the filter plate when the solution is directly squeezed out of the sampling tube, ensuring the purity of the sample and further improving the accuracy of the test results.

[0013] Preferably, the outer wall of the sealing column and the inner wall of the sampling tube are provided with mating threads.

[0014] After sampling is completed, the outer wall of the sealing column and the inner wall of the sampling tube have mating threads. By rotating the sealing column, it can be easily screwed into the sampling tube along the threads, thus quickly sealing the sampling tube. The threaded connection allows the sealing column to be easily screwed in and out, which is convenient, quick, and saves operation time.

[0015] As a preferred embodiment, a first limiting plate is provided inside the sampling cylinder, and a connecting hole is provided on the first limiting plate. After the negative pressure cylinder is screwed into the sampling cylinder, the end face of the negative pressure cylinder abuts against the side wall of the first limiting plate.

[0016] When the negative pressure cylinder is screwed into the sampling cylinder, the end face of the negative pressure cylinder will abut against the side wall of the first limiting plate. Due to the obstruction of the first limiting plate, the solution in the sampling cylinder has difficulty contacting the negative pressure cylinder, thereby avoiding contamination of the negative pressure cylinder by the solution in the sampling cylinder.

[0017] As a preferred embodiment, the two end faces of the negative pressure cylinder are respectively provided with a second limiting plate and a third limiting plate. The second limiting plate is provided with an air hole coaxially arranged with the connecting hole, and the third limiting plate is provided with an installation hole for the pull rod to extend out.

[0018] During the operation of the negative pressure cylinder, when it is screwed into the sampling cylinder and abuts against the first limiting plate, the air hole on the second limiting plate, coaxial with the connecting hole, ensures smooth gas passage, thereby effectively transmitting the negative pressure to the sampling cylinder. The mounting hole on the third limiting plate allows the pull rod to extend, facilitating the operator to control the piston's movement to generate negative pressure. Simultaneously, the second and third limiting plates limit the piston's range of motion.

[0019] Preferably, a pull ring is provided at the end of the pull rod that extends out of the mounting hole.

[0020] The pull ring design allows operators to apply force more easily without having to hold the lever directly, improving the convenience and comfort of operation. Attached Figure Description

[0026] To further understand the content of this utility model, a detailed description of this utility model will be provided in conjunction with the accompanying drawings and embodiments. It should be understood that the embodiments are merely illustrative of this utility model and are not intended to limit it.

[0027] Example

[0028] like Figures 1-3 As shown; the sampling equipment used for testing Chinese medicine components in this embodiment mainly consists of a sampling cylinder 110, a sampling tube 120, a negative pressure system, a sealing plate 1601, etc.

[0029] The sampling cylinder 110 is a hollow container with internal threads on its inner wall and a first limiting plate 1101 inside. The first limiting plate 1101 has a connecting hole 1102. One end of the sampling cylinder 110 is connected to the sampling tube 120, which contains a filter plate 130. The negative pressure system includes a negative pressure cylinder 140. The outer wall of the negative pressure cylinder 140 has external threads, and both ends have a second limiting plate 1401 and a third limiting plate 1402, respectively. The second limiting plate 1401 has an air hole 1403 coaxial with the connecting hole 1102, and the third limiting plate 1402 has a mounting hole for the pull rod 1502 to extend out. A piston 1501 is located inside the negative pressure cylinder 140. One end of the pull rod 1502 is connected to the piston 1501, and the other end passes through the mounting hole and has a pull ring 1405 at its end. One end of the sealing plate 1601 is provided with a sealing post 1602, and the outer wall of the sealing post 1602 is provided with threads that mate with the inner wall of the sampling tube 120.

[0030] The operating principle of the sampling device used for testing the components of traditional Chinese medicine in this embodiment is as follows:

[0031] In use, first screw the negative pressure cylinder 140 into the sampling cylinder 110 through the thread until the end face of the negative pressure cylinder 140 abuts against the side wall of the first limiting plate 1101. At this time, the air hole 1403 on the second limiting plate 1401 corresponds to the connecting hole 1102 on the first limiting plate 1101.

[0032] Then, by pulling the lever 1502 via the pull ring 1405, the piston 1501 inside the negative pressure cylinder 140 moves upward, thereby generating negative pressure inside the sampling cylinder 110. Under the action of negative pressure, the herbal medicine solution is drawn into the sampling tube 120. When passing through the filter plate 130, small particles are blocked, and the filtered solution enters the sampling cylinder 110. After sampling is completed, the sealing column 1602 is rotated to screw it into the sampling tube 120, achieving a seal. Then, the negative pressure cylinder 140 is unscrewed, and the solution inside the sampling cylinder 110 is poured out from the opening.

[0033] The filter plate 130 effectively blocks small particles, ensuring the purity of the sample and improving the accuracy of the test results.

[0034] The first limiting plate 1101 prevents the solution from the sampling cylinder 110 from contaminating the negative pressure cylinder 140, and the sealing column 1602 prevents the solution from being contaminated by particles on the filter plate 130, thus ensuring sample quality. The threaded connection of the negative pressure cylinder 140, the threaded rotation of the sealing column 1602, and the setting of the pull ring 1405 all make the operation simple and convenient, saving time and effort.

[0035] The detachable negative pressure cylinder 140 facilitates cleaning and disinfection, avoids cross-contamination, and ensures the reliability of each sampling. At the same time, pouring the sampled solution out from the opening of the sampling cylinder 110 can effectively prevent the solution in the sampling cylinder 110 from being contaminated by the Chinese medicine particles attached to the filter plate 130 after passing through the filter plate 130.

[0036] In summary, the above are merely preferred embodiments of this embodiment. All equivalent changes and modifications made in accordance with the scope of the patent application of this embodiment shall fall within the scope of the patent of this embodiment.
