Description

Technical Field

[0001] This utility model relates to the field of liquid preparation technology, and in particular to a shaker. Background Technology

[0002] In the field of drug preparation, it is often necessary to dilute powders in vials or transfer liquid medications from ampoules to infusion bags. Thorough mixing of various medications or reagents within containers (such as ampoules or vials) is a crucial step. Shakers, as automated mixing devices, are widely used in this process. They generate high-frequency vibrations to accelerate the mixing of liquids and / or powders and liquids within the container, thereby ensuring the uniformity and stability of the drug composition and guaranteeing the safety and effectiveness of subsequent use.

[0003] Currently, common shakers typically feature a shaking platform with slots or limiting holes for holding reagent bottles. However, in practice, leakage frequently occurs due to reasons such as leaky bottle caps, residual droplets at the bottle opening, loosening of caps under frequent vibration and impact, or damage to the reagent bottles. The leaked solution accumulates inside the slot and around its perimeter.

[0004] Most existing placement tanks are blind or through-hole structures integrally formed with the shaking platform. This structure has significant cleaning defects: First, spilled medicine (especially sticky, corrosive, or bacteria-prone medicine) is very likely to remain in the gaps and corners of the tank, creating cleaning dead spots; Second, cleaning staff often need to use cotton swabs, small brushes, and other tools for tedious manual wiping, which is not only inconvenient and inefficient, but also makes it difficult to ensure thorough disinfection and poses a risk of cross-contamination. Utility Model Content

[0005] The purpose of this invention is to solve the problem that existing shaking equipment is difficult to clean up spilled medicine and poses a risk of cross-contamination. This invention provides a shaking device that allows workers to efficiently and conveniently clean spilled medicine from the shaking device while reducing the risk of cross-contamination.

[0006] To solve the above-mentioned technical problems, an embodiment of this utility model discloses a shaking device, comprising:

[0007] Vibration drive unit;

[0008] A shaking platform is connected to the vibration driving unit, which drives the shaking platform to generate vibration parallel to the plane of the shaking platform; multiple limiting holes are provided through the shaking platform.

[0009] A tray is detachably connected to the shaking platform; the tray is spaced below the shaking platform to define a receiving space between the tray and the shaking platform; multiple limiting holes on the shaking platform are connected to the receiving space, and each limiting hole and the receiving space together define a reagent bottle receiving part.

[0010] By adopting the above technical solution, this application incorporates a vibration drive unit to generate high-frequency micro-amplitude vibrations to ensure rapid and uniform mixing of reagents. The shaking platform and tray are detachably connected, allowing for separation in case of spillage or reagent bottle breakage. This fully exposes all potentially contaminated areas, including the entire upper surface of the tray (including any areas where residual reagent may have come into contact), the upper and lower surfaces of the shaking platform, and the inner wall of the limiting hole, enabling direct wiping, rinsing, or disinfection without any cleaning dead spots. This design solves the problem of traditional integrated shaking devices where cleaning tools struggle to reach crevices and holes, significantly reducing the risk of cross-contamination and significantly improving the ease of maintenance and safety of use.

[0011] According to another specific embodiment of the present invention, the tray and the shaking platform are connected by any one of the following methods: magnetic connection, screw connection, and snap-fit ​​connection.

[0012] According to another specific embodiment of the present invention, the limiting hole on the shaking platform has a variety of hole diameter specifications to adapt to reagent bottles of different sizes.

[0013] Using the above technical solution, various locating holes with different aperture sizes can be adapted to reagent bottles of various sizes, meeting the parallel processing needs of various drug preparations without the need to change the platform.

[0014] According to another specific embodiment of the present invention, the accommodating space includes a first height, which is 1.2 to 1.5 times the diameter of the reagent bottle body, and the diameter of each limiting hole is 0 mm to 2 mm larger than the diameter of its corresponding reagent bottle body.

[0015] The above technical solutions collectively create a space that allows reagent bottles to undergo limited micro-movements and slight tilting under inertia. When vibration causes the reagent bottle to tilt, the interaction between its own gravity and inertial force generates a restoring torque that helps the bottle return to its upright position, allowing it to automatically return to an upright state like a "roly-poly toy." This not only avoids bottle jamming or surface wear caused by rigid constraints but also ensures that all reagent bottles maintain a uniform and stable vertical posture after vibration stops, providing a precise and reliable gripping position for robotic arms or other holding devices, greatly improving solution preparation efficiency.

[0016] According to another specific embodiment of the present invention, the vibration driving unit includes:

[0017] A first motor, the first motor including an output shaft;

[0018] An eccentric block is fixedly connected to the output shaft of the first motor;

[0019] The first connector is fixedly connected to the shaking platform.

[0020] Using the above technical solution, the eccentric block is directly fixed to the output shaft of the first motor, which directly converts the rotational motion of the first motor into high-intensity centrifugal force, forcing the liquid in the reagent bottle on the shaker reagent bottle to form a violent vortex, so that samples of different densities and viscosities can be fully mixed. At the same time, the first motor transmits the vibration directly to the shaking platform through the first connector, avoiding energy loss and significantly improving mixing efficiency and consistency.

[0021] According to another specific embodiment of the present invention, the first connecting member includes an inner cavity, the first motor and the eccentric block are located in the inner cavity, and the first motor is fixed in the inner cavity.

[0022] By adopting the above technical solution, the first motor is fixed in the inner cavity of the first connector, forming a compact integrated structure, which effectively protects the first motor from external pollution and reduces operating noise.

[0023] According to another specific embodiment of the present invention, it further includes a rotation drive unit, which is connected to the first connector through a vibration damping connector, and the rotation drive module is used to drive the first connector and the shaking platform to rotate synchronously.

[0024] According to another specific embodiment of the present invention, the rotary drive unit includes:

[0025] Second motor;

[0026] A speed reducer connected to the second motor, the speed reducer including an output shaft;

[0027] The second connector is connected to the output shaft of the reducer, and the second connector is connected to the first connector via the vibration damping connector.

[0028] Using the above technical solution, the second motor of the rotary drive unit provides the original power. After the output torque is increased and the speed is reduced by the reducer, the output shaft drives the second connecting member to move. The second connecting member serves as a power transmission interface, which stably transmits the rotational motion of the reducer to the shaking platform through the first connecting member, thereby ensuring the smooth start and rotation of the shaking platform.

[0029] According to another specific embodiment of the present invention, the first connecting member includes a first flange portion, the second connecting member includes a second flange portion, the first flange portion and the second flange portion are arranged opposite each other vertically, and the vibration damping connecting member passes through the first flange portion and the second flange portion.

[0030] According to another specific embodiment of this utility model, the vibration damping connector is a vibration damping rubber sleeve.

[0031] By adopting the above technical solution, the excellent elasticity and damping properties of rubber materials can be used to effectively absorb and dissipate high-frequency vibration energy, achieving the best vibration isolation effect at the lowest cost. At the same time, the structure is simple, reliable, and durable. Attached Figure Description

To provide a deep understanding of this utility model, many specific details will be included in the following description. This utility model may also be implemented without using these details. Furthermore, to avoid confusion or obscuring the focus of this utility model, some specific details will be omitted in the description. It should be noted that, without conflict, the embodiments and features in the embodiments of this utility model can be combined with each other.

[0038] It should be noted that in this specification, similar reference numerals and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

They are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the device or element 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.

[0040] The terms “first”, “second”, etc., are used only to distinguish descriptions and should not be interpreted as indicating or implying relative importance.

[0041] In the description of this embodiment, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set up," "connected," and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this embodiment based on the specific circumstances.

[0042] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0043] refer to Figure 1 This application provides a shaking device 100, including a shaking platform 200, a tray 300, a vibration drive unit 400, a rotation drive unit 500, and a frame 600. The shaking platform 200 has multiple limiting holes 201 extending along the height direction Z, and the tray 300 is detachably connected to the shaking platform 200.

[0044] The tray 300 is spaced below the shaking platform 200 to define a receiving space 101 between the tray 300 and the shaking platform 200. Multiple limiting holes 201 on the shaking platform 200 are connected to the receiving space 101, and each limiting hole 201 and the receiving space 101 together define a reagent bottle receiving part 102.

[0045] Understandably, the detachable structure of the shaking platform 200 and the tray 300 achieves the dual functions of reliable positioning of the reagent bottle and convenient cleaning. That is, on the one hand, the limiting hole 201 on the shaking platform 200 allows the reagent bottle to enter or leave the reagent bottle receiving part 102, and the limiting hole 201 provides radial restraint to prevent the reagent bottle from tipping over or shifting during shaking; on the other hand, the tray 300 supports the weight of the reagent bottle from the bottom to ensure the stability of the reagent bottle's posture.

[0046] On the other hand, if liquid spillage or reagent bottle damage occurs during the shaking process, the tray 300 can be separated from the shaking platform 200 to thoroughly clean the upper surface 301 of the tray 300 and the shaking platform 200 without the need for complex disassembly of the whole machine, which greatly reduces the difficulty and time cost of equipment maintenance and effectively avoids cross-contamination.

[0047] For example, reagent bottles include vials and ampoules.

[0048] In this embodiment, both the shaking platform 200 and the tray 300 are disc-shaped and are arranged vertically opposite each other. Those skilled in the art will understand that in other embodiments, the shaking platform 200 and the tray 300 can also be other shapes, such as rectangles or polygons.

[0049] In this embodiment, the limiting hole 201 on the shaking platform 200 is circular to match the reagent bottle with a cylindrical outer contour. Those skilled in the art will understand that the limiting hole 201 can also be set to other shapes, such as rectangular, polygonal, etc.

[0050] The aforementioned vibration drive unit 400 is connected to the shaking platform 200; the vibration drive unit 400 is used to drive the shaking platform 200 to generate vibration. For example, the vibration drive unit 400 drives the shaking platform 200 to generate high-frequency micro-amplitude vibration parallel to the plane of the shaking platform 200, thereby achieving efficient and uniform mixing of the reagent solution.

[0051] The aforementioned rotary drive unit 500 is connected to the frame 600 and is located above the shaking platform 200. The rotary drive unit 500 is connected to the shaking platform 200 through the vibration damping connector 700 and is used to drive the shaking platform 200 to rotate.

[0052] For example, such as Figure 1As shown, the frame 600 includes a vertical support rod 610, a horizontal extension rod 620, and a support plate 630. The vertical support rod 610 extends along the height direction Z, and the horizontal extension rod 620 extends along the horizontal direction X, perpendicularly connected to the vertical support rod 610. One end of the horizontal extension rod 620 away from the vertical support rod 610 is fixedly connected to the support plate 630. The rotary drive unit 500 is fixedly connected to the support plate 630. That is, the vertical support rod 610 raises the shaking platform 200 connected to the rotary drive unit 500 to a specific height, providing unobstructed movement space for the rotation and oscillation of the reagent bottle; the horizontal extension rod 620 extends the support plate 630 horizontally above the shaking platform 200, facilitating the connection between the rotary drive unit 500 and the shaking platform 200.

[0053] like Figure 2 As shown, the shaker 100 of this embodiment also includes a housing 800, which covers the rotary drive unit 500. The housing 800 encloses the rotary drive unit 500, effectively isolating it from external dust, liquids and chemical reagents, significantly improving the service life and reliability of precision components; at the same time, it reduces the mechanical noise during equipment operation and improves the working environment.

[0054] refer to Figure 1 The rotary drive unit 500 drives the shaking platform 200 to rotate via the vibration damping connector 700. The tray 300, connected to the shaking platform 200, rotates synchronously with the shaking platform 200, thereby changing the relative position of the reagent bottle receiving section 102 used to hold reagent bottles. That is, multiple reagent bottle receiving sections 102 can be sequentially transferred to fixed operating stations, allowing the shaken reagent bottles to be precisely stopped in a position easily grasped by a robotic arm or a person. Simultaneously, empty reagent bottle receiving sections 102 are rotated to a position convenient for loading reagent bottles to be shaken. This rotary scheduling mechanism can traverse all stations without moving the robotic arm, significantly improving the automation efficiency and ease of operation of the "shaking-transfer-receiving" process.

[0055] The aforementioned vibration damping connector 700 is used to isolate the transmission of vibration from the shaking platform 200 to the rotary drive unit 500. Specifically, the rotary drive unit 500, as a power source, drives the shaking platform 200 to rotate via the vibration damping connector 700. The elastic damping characteristics of the vibration damping connector 700 can effectively absorb and dissipate the high-frequency vibration energy of the shaking platform 200, forming a physical barrier to vibration transmission and preventing the vibration from being transmitted back to the rotary drive unit 500. This significantly reduces the failure rate of the rotary drive unit 500, extends its service life, and ensures the smoothness and control accuracy of the rotational motion.

[0056] By adopting the above technical solution, this application sets up a vibration drive unit 400 to generate high-frequency micro-amplitude vibration to ensure rapid and uniform mixing of reagents. A rotation drive unit 500 drives the shaking platform 200 to rotate via a vibration damping connector 700, changing the relative position of the reagent bottle receiving section 102, facilitating the handling or placement of reagent bottles. Specifically, the shaking platform 200 and the tray 300 are designed for detachable connection. In the event of spillage or damage to the reagent bottle, the shaking platform 200 and the tray 300 can be separated. The entire upper surface 301 of the tray 300 (including the area where residual reagent may contact), the upper and lower surfaces of the shaking platform 200, and the inner wall of the limiting hole 201—all potentially contaminated areas—are fully exposed, allowing for direct wiping, rinsing, or disinfection, ensuring no cleaning dead spots. This design solves the problem of traditional integrated shaking devices where cleaning tools cannot reach crevices and holes, significantly reducing the risk of cross-contamination and significantly improving the ease of maintenance and safety of use.

[0057] In this embodiment, as Figure 1 As shown, the rotary drive unit 500 includes a second motor 510, a reducer 520, and a second connecting member 530. The second motor 510 is fixedly connected to the support plate 630 of the frame 600; the reducer 520 is connected to the second motor 510 and includes an output shaft (not shown); the output shaft is connected to the second connecting member 530, and the second connecting member 530 is connected to the shaking platform 200 via a vibration damping connector 700. Exemplarily, the second motor 510 is fixed above the support plate 630, and the reducer 520 is located below the support plate 630, and the two are connected.

[0058] For example, the second motor 510 of the rotary drive unit 500 provides the original power. After the output torque is increased and the speed is reduced by the reducer 520, the output shaft drives the second connector 530 to move. The second connector 530 serves as a power transmission interface, stably transmitting the rotational motion of the reducer 520 to the shaking platform 200, thereby ensuring the smooth start and rotation of the shaking platform 200.

[0059] In this embodiment, as Figure 1 and Figure 3As shown, the second connector 530 is fixedly connected to the shaking platform 200 via the first connector 410. Specifically, the second connector 530 includes a second column portion 531 and a second flange portion 532 coaxially connected. The second column portion 531 is connected to the output shaft of the reducer 520, and its lower end extends radially to form the second flange portion 532. The first connector 410 includes a first column portion 411 and a first flange portion 412 coaxially connected. The first column portion 411 is fixedly connected to the shaking platform 200, and its upper end extends radially to form the first flange portion 412. The second flange portion 532 and the first flange portion 412 are arranged vertically opposite to each other and are connected by a vibration damping connector 700, which effectively attenuates vibration while ensuring torque transmission.

[0060] In this embodiment, the vibration damping connector 700 is a vibration damping rubber sleeve. Three vibration damping rubber sleeves are spaced apart on the circumferential R of the second flange portion 532 and the first flange portion 412, connecting them vertically. Those skilled in the art will understand that in other embodiments, other numbers of vibration damping rubber sleeves can be selected, such as 2, 4, or 5. Furthermore, other vibration damping connectors 700 can also be selected, such as silicone damping rings.

[0061] refer to Figure 1 , Figure 3 and Figure 4 The vibration drive unit 400 includes the first connector 410, the first motor 420, and the eccentric block 430 described above. The eccentric block 430 is fixedly connected to the output shaft of the first motor 420. The first column portion 411 of the first connector 410 is hollow inside, forming an inner cavity 413, in which the first motor 420 and the eccentric block 430 are located.

[0062] For example, the first motor 420 is fixed in the inner cavity 413 of the first connector 410, forming a compact integrated structure, which effectively protects the first motor 420 from external contamination and reduces operating noise. The eccentric block 430 is directly fixed to the output shaft of the first motor 420, directly converting the rotational motion of the first motor 420 into high-intensity centrifugal force, forcing the liquid in the reagent bottle on the shaker reagent bottle container 102 to form a violent vortex, so that samples of different densities and viscosities are fully mixed. At the same time, the first motor 420 transmits the vibration directly to the shaking platform 200 through the first connector 410, avoiding energy loss and significantly improving mixing efficiency and consistency.

[0063] refer to Figure 3 and Figure 4 In this embodiment, the tray 300 and the shaking platform 200 are magnetically connected.

[0064] Specifically, such as Figure 4As shown, a first magnetic element 210 is fixedly connected to the lower surface of the shaking platform 200, and a second magnetic element 310 is fixedly connected to the upper surface 301 of the tray 300. The first magnetic element 210 and the second magnetic element 310 are magnetically attracted to each other, thereby achieving a detachable connection between the tray 300 and the shaking platform 200. For example, multiple pairs of first magnetic elements 210 and second magnetic elements 310 can be provided, so that the tray 300 and the shaking platform 200 have multiple magnetic connection points, thereby improving the stability of the connection between the tray 300 and the shaking platform 200.

[0065] In one embodiment, the first magnetic element 210 is a permanent magnet embedded in the lower surface of the shaking platform 200, and the second magnetic element 310 is a magnetically conductive material fixed to the upper surface 301 of the tray 300. The magnetic field of the permanent magnet causes the magnetically conductive material to generate an induced magnetic field, and the two attract each other.

[0066] In another embodiment, the first magnetic element 210 and the second magnetic element 310 are permanent magnets with opposite poles (for example, the N pole of the first magnetic element 210 faces down and the S pole of the second magnetic element 310 faces up), which has a stronger magnetic force and a more secure attraction.

[0067] It is understood that this application does not limit the detachable connection method between the tray 300 and the shaking platform 200, such as screw connection, snap-fit ​​connection, etc.

[0068] refer to Figure 3 and Figure 5 It should be noted that, Figures 1 to 3 For simplicity, only one set of limiting hole groups 220 is shown. The aforementioned disc-shaped mixing platform 200 has eight sets of limiting hole groups 220 spaced at intervals R along its circumference. Each limiting hole group 220 includes five limiting holes 201 with different aperture sizes. These various aperture sizes of limiting holes 201 are compatible with various reagent bottles, meeting the parallel processing requirements for dispensing multiple drugs without needing to change the platform. All limiting hole groups 220 are arranged in a centrally symmetrical manner relative to the rotation center of the mixing platform 200.

[0069] It is understood that in other embodiments, the shaking platform 200 may have other numbers of limiting hole groups 220 distributed at intervals along its circumferential direction R, such as 5, 6, 7, 9, etc. Furthermore, each limiting hole group 220 may include other numbers of limiting holes 201 with different specifications and diameters, such as 2, 3, 4, 6, etc.

[0070] Furthermore, such as Figure 4As shown, the accommodating space 101 includes a first height H, which is the distance between the shaking platform 200 and the tray 300. The first height H is 1.2 to 1.5 times the diameter of the reagent bottle body, for example, the first height H can be 1.2, 1.3, 1.4, 1.5 times, etc., the diameter of the reagent bottle body.

[0071] The diameter of each limiting hole 201 is 0mm-2mm larger than the diameter of the corresponding reagent bottle body. For example, the diameter of each limiting hole 201 can be the same as the diameter of the corresponding reagent bottle body, or the diameter of each limiting hole 201 can be 1mm, 1.5mm, 2mm larger than the diameter of the corresponding reagent bottle body, etc.

[0072] by Figure 5 Taking one of the limiting hole groups 220 shown as an example, two limiting holes 201a and 201b with different diameters, where the diameter of limiting hole 201a is 12.5 mm, the diameter of the reagent bottle corresponding to limiting hole 201a ranges from 10.5 mm to 12.5 mm. This size range corresponds to a common 1 mL ampoule (corresponding to a diameter of 10 mm to 12 mm). In other words, the reagent bottle receiving part 102 corresponding to limiting hole 201a can accommodate a common 1 mL ampoule (corresponding to a diameter of 10 mm to 12 mm) and shake the solution inside to mix it.

[0073] The other limiting hole 201b has a diameter of 29 mm. Therefore, the diameter of the reagent bottle corresponding to this limiting hole 201b ranges from 27 mm to 29 mm. This size range corresponds to a common 20 mL vial (corresponding to a diameter of 28.5 mm). In other words, the reagent bottle receiving part 102 corresponding to this limiting hole 201b can accommodate a common 20 mL vial (corresponding to a diameter of 28.5 mm) and can shake and mix the powder and solution inside.

[0074] It should be noted that the aperture values ​​of the limiting holes 201a and 201b mentioned above are only exemplary. In other embodiments, the aperture of the corresponding limiting hole 201 can be set according to the specific specifications of the reagent bottle to be shaken.

[0075] Thus, the reagent bottle housing 102 forms a space that allows the reagent bottle to make limited micro-movements and slight tilts under inertia. When vibration causes the reagent bottle to tilt, the interaction between its own gravity and inertial force generates a restoring torque that helps the bottle return to its upright position, allowing it to automatically return to an upright state like a "roly-poly toy." This not only avoids bottle jamming or surface wear caused by rigid constraints, but also ensures that all reagent bottles maintain a uniform and stable vertical posture after vibration stops, providing a precise and reliable gripping posture for robotic arms or other clamping devices, greatly improving solution preparation efficiency.

[0076] Although the present invention has been illustrated and described with reference to certain preferred embodiments, those skilled in the art should understand that the above description is a further detailed explanation of the present invention in conjunction with specific embodiments, and should not be construed as limiting the specific implementation of the present invention to these descriptions. Those skilled in the art can make various changes in form and detail, including some simple deductions or substitutions, without departing from the spirit and scope of the present invention.
