Description

Technical Field

[0001] The invention belongs to the technical field of medical equipment, and in particular relates to a portable drug detection device. Background Art

[0002] Drug testing equipment is an indispensable tool in drug production and quality control, mainly used to ensure the safety, effectiveness and stability of drugs. These devices analyze and test drugs through various technical means to comply with relevant regulations and standards. Drug testing equipment plays an important role in drug research and development, production and post-marketing monitoring. During the research and development stage, researchers use these devices to analyze drug ingredients, determine their purity and concentration, and ensure that the drug is formulated appropriately.

[0003] In the prior art, a Chinese patent with publication number "CN114371264B" discloses a drug testing device, which conveniently drives the outer end of the moving component to clamp on the outside of the capsule through a moving ring, prevents the flexible capsule from being damaged by a split air bag, facilitates the disassembly of the capsule by moving the long rod left and right, and facilitates the dumping of the disassembled capsule by tilting the moving plate, thereby reducing the waste of drugs and solving the problem of the current capsule shell. In the early stage of the test, the workers need to disassemble the capsule shell to pour out the particles inside the capsule shell. When the workers operate by hand, there is a problem of bacterial contamination.

[0004] However, the above device still has the following problems during implementation: during the capsule fixing process, medical staff need to manually move the capsule to the center position of the two sets of clamping components, but the capsule is small in size and usually has an arc-shaped surface design, which makes it very difficult to pick up. It is impossible to keep the capsule in the center position when the clamping components move relatively, which is very inconvenient to use. To this end, we provide a portable drug detection device to solve the above problems. Summary of the invention

[0047] The working principle of the present invention is as follows: the experimenter puts the drug capsule to be tested into the drug inlet tube 2, and the capsule entering the drug inlet tube 2 will move vertically downward, and the capsule will be blocked by the limit seat 8, leaving the top of the capsule in the drug inlet tube 2;

[0048] Then, the hydraulic rod 15 is started by the external controller, and the hydraulic rod 15 cooperates with the adjusting rod 16 to drive the pulley 24 to move, and the pulley 24 pushes the protrusion 7, and the protrusion 7 cooperates with the moving rod 6 to push the moving tube 4, and the moving tube 4 pushes the rubber ring 5. After being squeezed, the rubber ring 5 tilts inward to fix the top of the capsule. Figure 8 As shown;

[0049] Then, the electric push rod 11 is started, and the electric push rod 11 drives the clamping plate 12 to fix the bottom of the capsule. The adjustment rod 16 moves downward and drives the vertical rod 25 and the horizontal rod 26 to move. When the horizontal rod 26 moves downward, it pushes the support rod 10. The support rod 10 cooperates with the clamping plate 12 to drive the bottom of the capsule to move downward, and the capsule is separated. After the capsule is separated, the powder particles will fall into the collection box 27 for collection;

[0050] Then, the support rod 10 is controlled to move downward. When the support rod 10 drives the movable shell 17 to contact the fixed shell 21, the fixed shell 21 prevents the movable shell 17 from moving downward. At this time, the support rod 10 continues to drive the gear 13 to move downward. Through the meshing action of the gear 13 and the toothed plate 14, the limit seat 8 and the bottom of the capsule are turned over, and all the powder particles inside the capsule are separated and fall into the collection box 27 for collection. Fig. 9 As shown, the entire detection process does not require the experimenter to hold the capsule to operate, which improves the convenience of operation and reduces bacterial contamination.
