Description

Technical Field

[0001] This utility model relates to the field of flange processing technology, specifically to a comparison test tube device for liquid generic drug analysis. Background Technology

[0002] Generic drugs are medicines that have the same active ingredients, dosage form, route of administration, and therapeutic effects as original drugs. They offer significant economic and social benefits, such as reducing healthcare expenditures, improving drug accessibility, and enhancing the level of healthcare services. Before production, generic drugs require analysis of the original drug, and before market approval, they also need to undergo consistency evaluations of quality and efficacy.

[0003] When analyzing generic drugs, it is often necessary to compare them with the original drug, observing aspects such as the color of the drug solution. This is done by sampling multiple test tubes and placing them on a test tube rack for comparison. Because the test tubes are in an open laboratory environment, prolonged direct contact between the drug solution and the external environment can easily lead to drug contamination.

[0004] Utility model patent CN214041113U discloses a comparison test tube device for analyzing liquid generic drugs, comprising: a container and a sample box. Several sample boxes are arranged side by side inside the container. Each sample box has a left sample slot and a right sample slot inside. A partition is provided between the left and right sample slots. A rotating flip cover is provided above the left and right sample slots. The two ends of the rotating flip cover are rotatably connected to the sample box via a rotating shaft. One side of the rotating flip cover is attracted to the partition via a first magnetic block, and the other side of the rotating flip cover is attracted to the sample box via a second magnetic block. Both the rotating flip cover and the partition are made of transparent material.

[0005] As shown in the above utility model, the existing comparison test tube device uses a sample box to place the sample test tubes inside, which isolates the medicine from the external environment and reduces drug contamination. The sample box is easy to open and convenient to replace different generic drug sample test tubes. However, this method separates the test tubes from the external environment by setting up the sample box, which is inconvenient for comparison. At the same time, when the sample box is opened, multiple test tubes inside the sample box come into contact with the external environment, and the problem of drug contamination is still not solved. Utility Model Content

[0006] To address the shortcomings of existing technologies, this invention provides a comparison test tube device for the analysis of liquid generic drugs, thus solving the aforementioned problems.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a comparison test tube device for the analysis of liquid generic drugs, comprising:

[0010] The connecting block has a slot in the middle, into which a test tube is inserted. The top of the test tube is provided with a sealing component, which is connected to the top of the vertical plate.

[0011] Preferably, the base plate has multiple equally spaced test tube slots, which are staggered with the vertical plates. The lower opening of each test tube slot is connected to a bottom support frame, and the upper ends of two adjacent vertical plates have corresponding slots symmetrically provided.

[0012] Preferably, magnetic grooves are provided on both sides of the connecting block, and an identification plate is attached to the magnetic groove.

[0013] Preferably, the sealing assembly includes a top plate that is attached to the top of the vertical plate. A handle is fixed to the middle of the upper surface of the top plate, and guide plates are fixed to both sides of the lower surface of the top plate.

[0014] Preferably, an elastic retaining plate is fixed at the middle of both sides of the lower surface of the top plate, the elastic retaining plate is located between the two guide plates, and the elastic retaining plate is adapted to the retaining groove.

[0015] Preferably, a telescopic rod is fixed to the middle of the lower surface of the top plate, a connecting plate is fixed to the bottom end of the telescopic rod, a spring is sleeved on the outer side of the telescopic rod, and a sealing gasket is adhered to the lower surface of the connecting plate, the sealing gasket corresponding to the opening of the test tube.

[0016] Beneficial effects

[0017] This invention provides a comparative test tube device for the analysis of liquid generic drugs. Compared with the prior art, it has the following advantages:

[0018] 1. This comparative test tube device for liquid generic drug analysis features a mounting frame on the base. Multiple vertical plates on the mounting frame, along with connecting blocks and a base plate, form multiple test tube slots, allowing the device to simultaneously hold multiple different test tubes for drug analysis comparison. Each test tube has a sealing assembly at its top. The connecting plate on the sealing assembly, along with a sealing gasket, seals the test tube opening, preventing the liquid inside from contacting the external environment. Furthermore, the multiple sealing assemblies ensure that opening a single test tube does not affect other test tubes, thus improving the analytical accuracy of this device.

[0019] 2. This comparative test tube device for liquid generic drug analysis features an elastic retaining plate on the top plate of the sealing assembly. The elastic retaining plate, in conjunction with the groove on the vertical plate, acts as a limiting element, ensuring a stable seal at the test tube opening while also facilitating rapid opening. The connecting plate on the sealing assembly is connected to the top plate via a telescopic rod and a spring, allowing the device to accommodate test tubes of different lengths and thus expanding the applicability of the sealing assembly.

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.

[0025] Please see Figure 1-3 This utility model provides two technical solutions:

[0026] First embodiment: A comparative test tube device for liquid generic drug analysis includes a base 1, a mounting frame 2 fixed on the top of the base 1, the mounting frame 2 is composed of multiple equally spaced vertical plates 21 and a base plate 22, the upper ends of two adjacent vertical plates 21 are connected by a connecting block 3, multiple equally spaced test tube slots are opened on the base plate 22, the test tube slots are staggered with the vertical plates 21, a bottom support frame 23 is connected to the lower opening of the test tube slot, the bottom support frame 23 is composed of multiple arc-shaped baffles, which provide support without affecting the experimenter's observation of the bottom of the test tube 4, and the upper ends of two adjacent vertical plates 21 are symmetrically provided with slots 24.

[0027] A slot 31 is provided in the middle of the connecting block 3. The slot 31 cooperates with the test tube slot to form a test tube slot 31. A test tube 4 is inserted into the slot 31. Magnetic grooves 32 are provided on both sides of the connecting block 3. A label is attached to the magnetic groove 32. The label numbers different test tubes 4 for easy identification. A sealing component 5 is provided at the top of the test tube 4. The sealing component 5 is connected to the top of the vertical plate 21. The sealing component 5 seals the mouth of the test tube 4 to prevent the liquid in the test tube 4 from contacting the external environment.

[0028] The main difference between the second implementation method and the first implementation method is that:

[0029] The sealing assembly 5 includes a top plate 51, which is attached to the top of the vertical plate 21. A handle 52 is fixed to the middle of the upper surface of the top plate 51, which facilitates the up-and-down movement of the top plate 51. Guide plates 53 are fixed to both sides of the lower surface of the top plate 51, and the guide plates 53 are attached to the upper sidewalls of the vertical plate 21. The guide plates 53 facilitate the insertion of the sealing assembly 5 between the two vertical plates 21. Elastic retaining plates 54 are fixed to the middle of both sides of the lower surface of the top plate 51, and the elastic retaining plates 54 are located between the two guide plates 53. 4 is adapted to the slot 24, which plays a limiting role, so that the sealing assembly 5 can be stably connected to the mounting frame 2. A telescopic rod 55 is fixed in the middle of the lower surface of the top plate 51. A connecting plate 56 is fixed at the bottom end of the telescopic rod 55. A spring 57 is sleeved on the outside of the telescopic rod 55. A sealing gasket 58 is glued to the lower surface of the connecting plate 56. The sealing gasket 58 corresponds to the opening of the test tube 4. The connecting plate 56 and the sealing gasket 58 can seal the opening of the test tube 4. The telescopic rod 55 and the spring 57 work together to make the sealing assembly 5 adaptable to test tubes 4 of different lengths.

[0030] When the device is in operation, multiple test tubes 4 are first inserted into different slots 31 until the bottom of the test tube 4 is inserted into the test tube slot. Then, the top plate 51 is moved to the top of the vertical plate 21 by the handle 52. The guide plate 53 on the top plate 51 makes it easy to insert the sealing assembly 5 between the two vertical plates 21 until the elastic card plate 54 on the top plate 51 is inserted into the card slot 24 on the vertical plate 21. At this time, the sealing assembly 5 is stably connected to the mounting frame 2. At this time, the sealing gasket 58 on the connecting plate 56 contacts the mouth of the test tube 4 and seals the mouth of the test tube 4. The spring 57 sleeved on the outside of the telescopic rod 55 makes the sealing gasket 58 fit tightly with the mouth of the test tube 4. At the same time, it can adapt to test tubes 4 of different lengths. The magnetic grooves 32 on both sides of the connecting block 3 are magnetically connected to the corresponding identification plates. The identification plates can mark the samples in the test tube 4, which is convenient for the staff to quickly identify.
