Description

Technical Field

[0001] The utility model belongs to the technical field of pharmaceutical intermediates, and specifically relates to a pharmaceutical intermediate sampling device. Background Art

[0002] Pharmaceutical intermediates refer to chemical raw materials or chemical products that play a bridging role in the process of drug synthesis. They are compounds required in one or more intermediate steps in the drug production chain. At present, pharmaceutical intermediates need to use special pharmaceutical intermediate sampling devices to detect them during the production process.

[0003] Existing pharmaceutical intermediate sampling devices usually use a needle to extract pharmaceutical intermediates. However, in this way, after the sampling is completed, the pharmaceutical paste in the sampling cavity is not easy to clean. If it is not cleaned thoroughly, there will be residues in the cavity. When it is used next time, this residue will be mixed with the new drug, affecting the accuracy of the intermediate inspection. Secondly, there are also devices that can disassemble the tube body, but most of them use a threaded connection. If this connection method is screwed too tight, it will be difficult for users with less strength to open it for cleaning. Utility Model Content

[0004] In view of this, the utility model provides a pharmaceutical intermediate sampling device, which can be disassembled by a relevant user with just one press through a fixing mechanism, making it more convenient to clean the pharmaceutical intermediate sampling device, preventing the problem of mutual contamination when sampling different pharmaceutical intermediates, and solving the problem that it is difficult for users with less strength to open the device due to the threaded connection method.

[0005] In order to solve the above technical problems, the utility model provides a pharmaceutical intermediate sampling device, including a sampling tube and a container head and a connecting assembly arranged between the sampling tube and the container head, the connecting assembly including an annular plug arranged on the upper end surface of the sampling tube, the lower end surface of the container head is provided with a slot adapted to the annular plug, the middle part of the container head is also provided with a sampling assembly, the sampling assembly includes a cross slide groove arranged in the middle part of the container head, a cross slide rod is slidably connected in the cross slide groove, a piston is threadedly connected in a screw hole arranged in the middle part of the lower surface of the cross slide rod, the whole composed of the sampling tube and the container head is arranged in cooperation with the piston, a fixing mechanism is also provided between the sampling tube and the container head, and an ejection assembly is also provided in the slot.

[0006] A scale line is arranged on the right side of the outer arc surface of the sampling tube near the transparent window.

[0007] A transparent window is arranged in the opening arranged on the right side of the outer arc surface of the sampling tube.

[0008] The lower end of the sampling tube is movably plugged with a movable connector.

[0009] The fixing mechanism includes an assembly groove which is longitudinally symmetrically arranged at the lower end of the outer arc surface of the container head. The upper side of the inner cavity of the assembly groove is rotatably connected to a limit clamp. The upper end surface of the sampling tube is provided with a limit plate which is longitudinally symmetrically distributed. The limit plates are respectively matched with the limit clamps adjacent to the same side; the fixing mechanism also includes spring pieces which are respectively arranged at the upper end of the inner wall surface of the assembly groove. The lower ends of the spring pieces are respectively matched with the limit clamps adjacent to the same side.

[0010] The ejection assembly comprises a spring arranged on the top wall of the slot, a rubber sealing top ring is arranged at the lower end of the spring, the rubber sealing top ring is slidably connected to the slot, and the rubber sealing top ring is matched with the annular plug.

[0011] The beneficial effects of the above technical solution of the utility model are as follows:

[0012] 1. When other samples need to be taken after the sampling of the pharmaceutical intermediate sample is completed, the relevant staff only needs to press the limit clamp at the same time, and the limit clamp overcomes the elastic force of the spring and retracts into the assembly groove, so that the limit clamp is separated from the limit plate, and then the annular plug and the sampling tube are separated from the container head through the rubber sealing top ring under the action of the spring rebound force. The sampling tube and the container head can be opened with just one press, and then the sampling tube and the container head and their ancillary mechanisms can be cleaned. The relevant user only needs to press it to disassemble, which makes it more convenient to clean the pharmaceutical intermediate sampling device, prevents the problem of mutual contamination when sampling different pharmaceutical intermediates, and solves the problem that users with less strength are difficult to open due to the threaded connection method.

[0013] 2. After cleaning, just align the limit plate with the assembly groove, and then flexibly connect the annular plug on the sampling tube with the slot on the container head. After the limit plate contacts the limit clamp, the limit plate will slide relative to the limit clamp, and the limit clamp will overcome the elastic force of the spring piece to avoid. After the sampling tube and the container head are fully matched, the limit clamp will immediately reset under the action of the spring piece's rebound force and connect with the limit plate, thereby locking the sampling tube and the container head. At this time, the spring is compressed and exerts a reverse force on the rubber sealing top ring, so that the rubber sealing top ring tightly contacts the annular plug. Disassembly and installation can be achieved by one click and one plug, making it more convenient for relevant users to operate. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] like Figure 1As shown, the ejection assembly includes a spring 700 arranged on the top wall of the slot 301, and a rubber sealing top ring 701 is provided at the lower end of the spring 700. The rubber sealing top ring 701 is slidably connected to the slot 301, and the rubber sealing top ring 701 is matched with the annular plug 300.

[0023] like Figure 1-4 As shown, a transparent window 800 is provided in the opening on the right side of the outer arc surface of the sampling tube 100 to facilitate observation by relevant users.

[0024] like Figure 1-2 As shown, a movable connector 500 is movably connected to the lower end of the sampling tube 100 to facilitate replacement by relevant users.

[0025] The working principle of the pharmaceutical intermediate sampling device provided by the utility model is as follows: when sampling is required, the relevant user holds the sampling tube 100 and its auxiliary mechanism, and then inserts the movable connecting head 500 into the storage place of the pharmaceutical intermediate required for sampling, and then the relevant user pulls the cross slide bar 400 outward, and the cross slide bar 400 drives the piston 401 to move to generate negative pressure suction, so that the pharmaceutical intermediate is drawn into the cavity formed by the sampling tube 100 and the container head 200, and then only needs to press the cross slide bar 400 to move the pharmaceutical intermediate sample into the specified inspection tube. After the sampling of the pharmaceutical intermediate sample is completed, when other samples need to be taken, the relevant staff only needs to press the limit clamp 601 at the same time, and the limit clamp 601 overcomes the elastic force of the spring 603 and retracts into the assembly groove 600, so that the limit clamp 601 is separated from the limit plate 602, and then the annular plug 300 and the sampling tube 100 are separated from the container head 200 through the rubber sealing top ring 701 under the action of the rebound force of the spring 700.

After cleaning, it is only necessary to align the limiting plate 602 with the assembly groove 600, and then flexibly connect the annular plug 300 on the sampling tube 100 with the slot 301 on the container head 200. After the limiting plate 602 contacts the limiting clamp 601, the limiting plate 602 will slide relative to the limiting clamp 601, and The limit clamp 601 overcomes the elastic force of the spring piece 603 and avoids it. After the sampling tube 100 and the container head 200 are fully matched, the limit clamp 601 is immediately reset under the action of the rebound force of the spring piece 603 and clamped on the limit plate 602, thereby locking and limiting the sampling tube 100 and the container head 200. At this time, the spring 700 is compressed and applies a reverse force to the rubber sealing top ring 701, so that the rubber sealing top ring 701 tightly contacts the annular plug 300. Disassembly and installation can be achieved by just pressing and plugging, making it more convenient for relevant users to operate.
