Description

Technical Field

[0001] This utility model belongs to the field of pharmaceutical premixing technology, and specifically relates to a premixing device for pharmaceutical laboratories. Background Technology

[0002] During pharmaceutical trials, when a formulation contains extremely low doses of active pharmaceutical ingredients or trace amounts of functional excipients, these small amounts may not be evenly dispersed throughout the mixture if directly mixed with all other excipients at once. Therefore, it is necessary to premix the low-dose components with a small amount of filler or main excipients first, and then add this premix to the remaining large amount of excipients for final mixing to ensure uniformity of content.

[0003] In existing technologies, the medicine and excipients are generally poured into the hopper and then rotated to mix them inside. However, when sealing the hopper, the hopper and the cover plate need to be aligned so that the cover plate can be fixed to the top of the hopper with a snap fastener. Therefore, disassembling and installing the cover plate and the hopper takes a lot of time and is quite time-consuming and labor-intensive. Utility Model Content

[0004] To address the problem that mixing pharmaceuticals and excipients inside a hopper by pouring them in and rotating the hopper, which requires a aligning hopper and cover plate for sealing and securing the cover plate to the top of the hopper with clips, and the time-consuming and labor-intensive process of disassembling and installing the cover plate, this invention proposes a premixing device for pharmaceutical laboratories to overcome the aforementioned technical problems in existing related technologies.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to a premixing device for pharmaceutical testing laboratories, comprising a base:

[0007] The base is equipped with a drive assembly, a mixing assembly, a sealing assembly, and a snap-fit ​​assembly.

[0008] The drive component has its output end fixedly connected to the outer surface of the mixing component, so that the drive component drives the mixing component to premix the reagent;

[0009] A sealing assembly, the interior of which is sealed to the top of the mixing assembly, so that the sealing assembly seals the top of the mixing assembly;

[0010] A snap-fit ​​assembly, one side of which is fixedly connected to the outer surface of the sealing assembly, so that the snap-fit ​​assembly snaps and limits the position of the sealing assembly.

[0011] Furthermore, the drive assembly includes a motor, one side of which is fixedly mounted to one side of the base, and a connecting shaft is fixedly connected to the output end of the motor.

[0012] Furthermore, the mixing assembly includes a hopper, the outer surface of which is fixedly connected to one end of the connecting shaft, and a discharge pipe is fixedly connected to the bottom end of the hopper, with a sealing cap fitted on the outer surface of the discharge pipe.

[0013] Furthermore, the sealing assembly includes a sealing cap, the inside of which is fitted into the top of the hopper, a card is fixedly connected inside the sealing cap, and a handle is fixedly connected to the outer surface of the sealing cap.

[0014] Furthermore, the sealing assembly also includes a limiting ring, the inside of which is fixedly connected to the outer surface of the hopper, and a connecting groove is provided at the top of the limiting ring, the inside of which is slidably disposed with the outer surface of the card.

[0015] Furthermore, the snap-fit ​​assembly includes a mounting plate, one side of which is fixedly connected to the outer surface of the hopper. A mounting cylinder is fixedly mounted on the bottom end of the mounting plate. A connecting plate is slidably arranged inside the mounting cylinder. A spring is fixedly connected to the bottom end of the connecting plate. A pull rod is fixedly connected to the bottom end of the connecting plate. A handle is fixedly connected to the bottom end of the pull rod.

[0016] Furthermore, the snap-fit ​​assembly also includes a limiting block, one side of which is fixedly connected to the outer surface of the sealing cover. The limiting block has a slot inside, and a wedge is snap-fitted inside the slot. The bottom end of the wedge is fixedly connected to the top end of the connecting disc.

[0017] This utility model has the following beneficial effects:

[0018] 1. This utility model involves placing a sealing component on top of a mixing component and rotating the sealing component. During the rotation of the sealing component, the locking component fixed on the outer surface rotates in a circular motion, allowing the locking component to engage and limit the sealing component during rotation. This allows the sealing component to seal the top of the mixing component. Furthermore, by pulling the locking component, the locking component can be released from the top of the mixing component, making it easy to remove the sealing component from the top of the mixing component. This method is time-saving and labor-saving.

[0019] 2. When the handle is pulled, the pull rod moves downward, which in turn moves the connecting plate downward. This allows the connecting plate to disengage the wedge block from the slot, facilitating the rotation of the sealing cover. This makes it easier to disassemble and install the sealing cover, which is quite convenient.

[0020] Of course, any product implementing this utility model does not necessarily need to achieve all of the above advantages at the same time. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the utility model, and not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the utility model.

[0031] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "top", "middle", "inner", etc., which indicate orientation or positional relationship, are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the utility model.

[0032] Please see Figures 1-6 As shown, this utility model is a premixing device for a pharmaceutical laboratory, including a base 1:

[0033] The base 1 is respectively equipped with a drive assembly 2, a mixing assembly 3, a sealing assembly 4, and a snap-fit ​​assembly 5;

[0034] The drive component 2 has its output end fixedly connected to the outer surface of the mixing component 3, so that the drive component 2 drives the mixing component 3 to premix the agent;

[0035] The sealing component 4 is internally sealed to the top of the mixing component 3 so that the sealing component 4 seals the top of the mixing component 3.

[0036] The snap-fit ​​component 5 has one side fixedly connected to the outer surface of the sealing component 4 so that the snap-fit ​​component 5 snaps and limits the position of the sealing component 4.

[0037] In use, the medicine and excipients are poured into the interior of the mixing assembly 3, and then the sealing assembly 4 is placed on the top of the mixing assembly 3. The sealing assembly 4 is rotated so that the outer surface of the sealing assembly 4 is driven to rotate in a circular motion, so that the locking assembly 5 is locked and limited during the rotation, so that the locking assembly 5 locks and limits the sealing assembly 4, thereby sealing the top of the mixing assembly 3. Then, the drive assembly 2 is started to drive the mixing assembly 3, which is fixed at the output end, to rotate, so that the mixing assembly 3 can mix the medicine and excipients inside.

[0038] This invention involves placing the sealing component 4 on the top of the mixing component 3 and rotating the sealing component 4. During the rotation of the sealing component 4, the locking component 5 fixed on the outer surface moves in a circular motion, so that the locking component 5 engages and limits the sealing component 4 during rotation. This allows the sealing component 4 to seal the top of the mixing component 3. By pulling the locking component 5, the locking and limiting of the sealing component 4 can be released, making it easy to remove the sealing component 4 from the top of the mixing component 3, which is time-saving and labor-saving.

[0039] In one embodiment, the drive component 2 includes a motor 201, one side of which is fixedly mounted to one side of the base 1, and the output end of the motor 201 is fixedly connected to a connecting shaft 202.

[0040] The motor 201 drives the fixed connecting shaft 202 at the output end to rotate, so that the connecting shaft 202 rotates around the inside of the base 1, thereby improving the stability of the connecting shaft 202 during rotation.

[0041] In one embodiment, the mixing component 3 includes a hopper 301, the outer surface of the hopper 301 is fixedly connected to one end of the connecting shaft 202, the bottom end of the hopper 301 is fixedly connected to a discharge pipe 302, and the outer surface of the discharge pipe 302 is fitted with a sealing cap 303.

[0042] The motor 201 drives the connecting shaft 202, which is fixed at the output end, to rotate. This causes the connecting shaft 202 to rotate the hopper 301, which is fixed at one end. The hopper 301, in conjunction with the discharge pipe 302 fixed at the bottom, rotates the sealing cover 303. This facilitates the mixing of the medicine and excipients inside the hopper 301. The mixed material inside the hopper 301 can be easily removed by opening the sealing cover 303.

[0043] In one embodiment, the sealing assembly 4 includes a sealing cover 401, the inside of the sealing cover 401 is sleeved with the top of the hopper 301, a card 402 is fixedly connected to the inside of the sealing cover 401, and a handle 403 is fixedly connected to the outer surface of the sealing cover 401.

[0044] The sealing assembly 4 also includes a limiting ring 404, the inside of which is fixedly connected to the outer surface of the hopper 301, and a connecting groove 405 is provided at the top of the limiting ring 404, the inside of which is slidably disposed with the outer surface of the card 402.

[0045] By gripping the handle 403, the sealing cap 401, fixed at one end, is moved to the top of the hopper 301, and the sealing cap 401 is fitted onto the top of the hopper 301. This causes the sealing cap 401 to bring the internally fixed card 402 into contact with the top of the limiting ring 404. Then, by rotating the handle 403 in conjunction with the sealing cap 401, the card 402 rotates at the top of the limiting ring 404. During this movement, the card 402 enters the connecting groove 405 under the weight of the sealing cap 401. Then, the card 402 is rotated again so that the top of the card 402 is in contact with the bottom of the limiting ring 404, thereby facilitating the fixing of the sealing cap 401 and sealing the top of the hopper 301.

[0046] In one embodiment, the snap-fit ​​assembly 5 includes a mounting plate 501. One side of the mounting plate 501 is fixedly connected to the outer surface of the hopper 301. A mounting cylinder 502 is fixedly mounted at the bottom end of the mounting plate 501. A connecting plate 503 is slidably arranged inside the mounting cylinder 502. A spring 504 is fixedly connected to the bottom end of the connecting plate 503. A pull rod 505 is fixedly connected to the bottom end of the connecting plate 503. A handle 506 is fixedly connected to the bottom end of the pull rod 505.

[0047] The snap-fit ​​assembly 5 also includes a limiting block 507. One side of the limiting block 507 is fixedly connected to the outer surface of the sealing cover 401. A slot 508 is provided inside the limiting block 507. A wedge 509 is snap-fitted inside the slot 508. The bottom end of the wedge 509 is fixedly connected to the top end of the connecting plate 503.

[0048] When the sealing cover 401 rotates, it can drive the limiting block 507 fixed on the outer surface to rotate. Since the bottom of one side of the limiting block 507 is provided with an inclined surface, and one side of the inclined surface corresponds to the wedge surface of the wedge block 509, when the limiting block 507 moves, it can push the wedge block 509 to move downward, so that the wedge block 509 can drive the bottom fixed connecting plate 503 to move. This causes the connecting plate 503 to compress the spring 504 along the direction of the bottom fixed pull rod 505. When the limiting block 507 drives the internal slot 508 to move directly above the wedge block 509, the spring 504 releases the compression force, so that it can cooperate with the connecting plate 503 to push the wedge block 509 into the inside of the slot 508, so that the wedge block 509 can cooperate with the limiting block 507 to fix the position of the sealing cover 401, so as to ensure the sealing performance of the sealing cover 401 to the hopper 301.

[0049] At the same time, when the handle 506 is pulled, it can drive the pull rod 505 to move downward, so that the pull rod 505 drives the connecting plate 503 to move downward, thereby enabling the connecting plate 503 to drive the wedge block 509 to disengage from the inside of the slot 508, so that the sealing cover 401 can be rotated again, thus facilitating the disassembly and installation of the sealing cover 401, which is more convenient.

[0050] Through the above technical solution, 1. by fitting the sealing component 4 onto the top of the mixing component 3 and rotating the sealing component 4, the outer surface of the locking component 5 is driven to rotate in a circular motion during the rotation of the sealing component 4, so that the locking component 5 locks and limits the sealing component 4 during the rotation, thereby enabling the sealing component 4 to seal the top of the mixing component 3. Furthermore, by pulling the locking component 5, the locking and limiting of the sealing component 4 can be released, so that the sealing component 4 can be removed from the top of the mixing component 3, which is more time-saving and labor-saving.

[0051] 2. When the handle 506 is pulled, it can drive the pull rod 505 to move downward, so that the pull rod 505 drives the connecting plate 503 to move downward, thereby enabling the connecting plate 503 to drive the wedge block 509 to disengage from the inside of the slot 508, so that the sealing cover 401 can be rotated again, thus facilitating the disassembly and installation of the sealing cover 401, which is more convenient.
