Description

Technical Field

[0001] This utility model relates to the field of sampling technology, specifically a quantitative sampling and analysis device for pharmaceuticals. Background Technology

[0002] Pharmaceutical analysis is a discipline that uses chemical, physical, or biological methods to qualitatively, quantitatively, and qualitatively evaluate the drug components in active pharmaceutical ingredients, formulations, and biological samples, ensuring the safety, efficacy, and stability of drugs.

[0003] In the prior art, patent announcement number CN220289110U discloses a device for quantitative sampling of liquid drugs, including an outer tube and a base plate. The outer tube includes a straight cylindrical part and a conical connecting part integrally connected to the bottom end of the straight cylindrical part. A liquid extraction part is integrally fixedly connected to the bottom end of the conical connecting part. A retaining ring is integrally fixedly connected to the top end of the straight cylindrical part. A piston plate is installed on the inner wall of the straight cylindrical part. A threaded rod is rotatably connected to the top of the piston plate. A fixing plate is fixedly connected to the inner wall of the straight cylindrical part. A threaded sleeve is fixedly inserted into the middle of the fixing plate, and the threaded rod is threadedly inserted into the inside of the threaded sleeve. A handle is fixedly connected to the top end of the threaded rod.

[0004] The aforementioned device achieves drug sampling through the cooperation of an outer tube and a piston plate. However, in some cases, to ensure sample diversity and accuracy, researchers may need to use multiple different drugs for sampling. During this process, the outer tube often becomes contaminated after sampling, necessitating frequent replacement of the outer tube to avoid cross-contamination between samples. This frequent replacement not only increases the complexity of the experiment but also makes the entire sampling process quite inconvenient. Utility Model Content

[0005] The purpose of this invention is to provide a quantitative sampling and analysis device for pharmaceuticals to solve the problems in the prior art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a quantitative sampling and analysis device for pharmaceuticals, comprising an upper shell, a lower shell connected below the upper shell, a movable sliding groove on the upper shell, a locking buckle between the upper shell and the lower shell, a sampling mechanism installed inside the lower shell, the sampling mechanism comprising a positioning sleeve fixedly installed inside the lower shell, a second spring provided inside the positioning sleeve, a tray movably installed inside the positioning sleeve, a storage tank provided on the tray, a sampling needle fixedly installed at the bottom of the storage tank, and a driving mechanism installed inside the upper shell.

[0007] Preferably, the sampling mechanism includes a piston slidably installed inside the storage tank and a first spring fixedly installed inside the storage tank, and a sampling push rod is fixedly installed on the piston.

[0008] Preferably, the bottom of the lower housing has an inlet / outlet hole, through which the sampling needle extends out of the lower housing; the upper end of the storage tank has a through hole, through which the sampling push rod extends out of the storage tank; and the storage tank is installed inside the lower housing by a positioning sleeve.

[0009] Preferably, one end of the first spring is connected to the piston, and the other end of the first spring is connected to the top of the storage tank. One end of the second spring is connected to the tray, and the other end of the second spring is connected to the bottom of the positioning sleeve. The upper shell and the lower shell are connected together by a locking mechanism.

[0010] Preferably, the driving mechanism includes a positioning plate fixedly installed inside the upper housing, the positioning plate having a movable hole, a driving rod movably installed in the movable hole, a return spring sleeved on the driving rod, a driving block fixedly installed at the upper end of the driving rod, and the driving block slidably installed on the outside of the upper housing through a movable groove, and a spring seat fixedly installed at the upper edge of the driving rod.

[0011] Preferably, the drive rod inside the upper housing is vertically aligned with the sampling push rod on the piston.

[0012] Preferably, the drive rod is slidably mounted on the positioning plate through the movable hole, one end of the return spring is connected to the positioning plate, and the other end of the return spring is connected to the spring seat.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. In this application, after the user slowly releases the drive block, the first spring first performs a reset operation. During this reset process, the first spring moves upward by driving the piston, thereby drawing the drug into the storage tank using the sampling needle. Subsequently, the second spring also completes its reset, causing the storage tank to contract and reposition itself within the sleeve, thus completing the entire drug sampling process.

[0015] 2. In this application, after the driving block applies downward pressure, it will drive the driving rod to move downward, which in turn will drive the corresponding sampling push rod to move downward. The downward movement of the sampling push rod will sequentially compress the second spring and the first spring. When the second spring is compressed, the sampling needle will extend outside the lower housing; while when the first spring is compressed, the piston will move to the bottom of the storage tank. By pressing different driving blocks, the corresponding sampling needle can draw different types of drugs into the corresponding storage tank, thereby facilitating the sampling of multiple drugs.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figure 1 and Figure 2 As shown, this utility model provides a technical solution for a quantitative sampling and analysis device for pharmaceuticals, including an upper shell 1, a lower shell 4 connected below the upper shell 1, a movable sliding groove 2 on the upper shell 1, a locking buckle 3 between the upper shell 1 and the lower shell 4, a sampling mechanism 5 installed in the lower shell 4, and a driving mechanism 6 installed in the upper shell 1. Through the cooperation of the sampling mechanism 5 and the driving mechanism 6, users can conveniently sample different types of drugs.

[0023] like Figure 2 and Figure 3As shown, the sampling mechanism 5 includes a positioning sleeve 505 fixedly installed inside the lower housing 4. A second spring 507 is provided inside the positioning sleeve 505. A tray 506 is movably installed inside the positioning sleeve 505. A storage tank 502 is provided on the tray 506. A sampling needle 508 is fixedly installed at the bottom of the storage tank 502. The sampling mechanism 5 includes a piston 504 slidably installed inside the storage tank 502 and a first spring 503 fixedly installed inside the storage tank 502. A sampling push rod 501 is fixedly installed on the piston 504. An inlet and outlet hole is opened at the bottom of the lower housing 4. The sampling needle 508 extends out of the lower housing 4 through the inlet and outlet hole. A through hole is opened at the upper end of the storage tank 502. The sampling push rod 501 extends out of the storage tank 502 through the through hole. The storage tank 502 is installed inside the lower housing 4 through the positioning sleeve 505.

[0024] Specifically, after the user slowly releases the drive block 601, the first spring 503 begins its reset action. As the first spring 503 resets, it moves the piston 504 upwards, thereby drawing the drug into the storage container 502 using the sampling needle 508. Subsequently, after the first spring 503 has fully reset, the second spring 507 begins its reset action. After the second spring 507 resets, it causes the storage container 502 to retract until it is fully back inside the positioning sleeve 505. This series of precise mechanical actions ultimately completes the drug sampling process.

[0025] like Figure 2 and Figure 4 As shown, the drive mechanism 6 includes a positioning plate 605 fixedly installed inside the upper housing 1. The positioning plate 605 has a movable hole 606. A drive rod 604 is movably installed inside the movable hole 606. A return spring 603 is sleeved on the drive rod 604. A drive block 601 is fixedly installed on the upper end of the drive rod 604, and the drive block 601 is slidably installed on the outside of the upper housing 1 through the movable slide groove 2. A spring seat 602 is fixedly installed at the upper edge of the drive rod 604. The drive rod 604 inside the upper housing 1 is vertically aligned with the sampling push rod 501 on the piston 504.

[0026] Specifically, when the operator presses down on the drive block 601, the drive block 601 moves downwards. As the drive block 601 moves downwards, it further drives the connected drive rod 604 downwards. The downward movement of the drive rod 604 triggers a series of chain reactions, namely, the drive rod 604 pushes the corresponding sampling push rod 501 downwards. The downward movement of the sampling push rod 501 applies pressure to the second spring 507 and the first spring 503 in sequence, causing them to be compressed. When the second spring 507 is compressed to a certain extent, the sampling needle 508 extends from the opening of the lower housing 4 to draw up the drug. At the same time, the compression of the first spring 503 causes the piston 504 to move to the bottom of the storage tank 502. By selectively applying pressure to different drive blocks 601, the corresponding sampling needle 508 can be controlled to draw up different types of drugs and suck them into the corresponding storage tank 502. This design greatly simplifies the process of sampling and classifying various drugs, improving the convenience and efficiency of operation.

[0027] Working principle: In use, multiple storage tanks 502 are first placed in different positioning sleeves 505. Then, the upper shell 1 and the lower shell 4 can be connected together by the latch 3. When sampling, the drive block 601 can be pressed down. After the drive block 601 is pressed down, it will drive the drive rod 604 to move downward. After the drive rod 604 moves downward, it will drive the corresponding sampling push rod 501 to move downward. After the sampling push rod 501 moves downward, it will compress the second spring 507 and the first spring 503 in sequence. After the second spring 507 is compressed, the sampling needle 508 will extend out of the lower shell 4. After the first spring 503 is compressed, the piston 504 will move to the bottom of the storage tank 502. When the user slowly releases the drive block 601, the first spring 503 will first reset. During the reset process, the first spring 503 will drive the piston 504 to move upward, thereby using the sampling needle 508 to draw the drug into the storage container 502 and store it. Then the second spring 507 will reset. After the second spring 507 resets, it will drive the storage container 502 to retract back into the positioning sleeve 505, completing the sampling of the drug.
