Description

Technical Field

[0001] This utility model relates to the field of oscillator technology, specifically to an oscillation device for clinical drugs. Background Technology

[0002] In the medical and scientific research fields, drug dissolution is a crucial step in preparing drug solutions. Especially for poorly soluble drugs, the dissolution rate and solubility often directly affect bioavailability and therapeutic efficacy.

[0003] There are many models and structures of existing drug shaking devices. They usually constrain the medicine bottle in an upright position on a vibration platform. Based on a motor and controller, the solution in the container is mixed and dissolved by providing up-and-down, rotation, back-and-forth, and swinging movements to the vibration platform.

[0004] In clinical medicine, drug fusion often involves mixing multiple drugs in large proportions. Due to differences in density or state of matter (solid or liquid) of different drugs, the distribution concentration of drugs varies greatly at different depths. Especially when encountering large-particle drugs or poorly soluble solid powders, the dissolution and mixing efficiency of existing shakers is not ideal. Utility Model Content

[0005] The purpose of this invention is to provide a shaking device for clinical drugs, which optimizes the way medicine bottles are fixed, improves the turbulence and collision of the solution, promotes drug dissolution and mixing, and improves mixing efficiency.

[0006] To achieve the above objectives, this utility model employs the following technical solution:

[0007] A vibration device for clinical drugs includes a vibration platform having a horizontal reciprocating vibration stroke.

[0008] A receiving groove is fixed on the vibration platform, and a support frame is fixed at the bottom of the receiving groove. The support frame includes multiple folded plate units connected in sequence along the horizontal reciprocating vibration stroke direction. Each folded plate unit includes a first support plate and a second support plate vertically connected to its bottom side. The second support plate is inclined relative to the vibration platform.

[0009] The support frame is provided with multiple limiting strips on its upper part. The length direction of the limiting strips corresponds to the horizontal reciprocating vibration stroke direction, and the spacing between the limiting strips is adjustable.

[0010] Furthermore, the groove wall of the receiving groove is symmetrically provided with strip-shaped holes, the strip-shaped holes are located at both ends of the limiting strip, and the two ends of the limiting strip are respectively fixed with screws extending in the same direction, the screws pass through the strip-shaped holes on the same side, and large nuts are threaded onto the screws.

[0011] Furthermore, the limiting strip is a cylindrical component, and the surface of the limiting strip is covered with a flexible foam layer or a silicone layer.

[0012] Furthermore, the top of the receiving groove is provided with an opening, and a baffle adapted to the opening is provided at the opening. Sliding grooves are provided on both sides of the opening, and the two sides of the baffle are movably inserted into the sliding grooves.

[0013] Furthermore, the second pallet is inclined at a 15-degree angle to the vibration platform.

[0014] Furthermore, the baffle and / or receiving groove are transparent components.

[0015] Furthermore, a main unit is provided below the vibration platform. The main unit includes a housing, and a horizontally arranged support frame is provided inside the housing. The support frame is used to provide a horizontal reciprocating vibration stroke for the vibration platform. Parallel track bars are provided on both sides of the support frame. Track grooves are provided on the top and bottom sides of the track bars. A pressure roller is fitted in the upper track groove, and a support roller is fitted in the lower track groove. The support roller and pressure roller on the same side are rotatably mounted on a strip plate. The strip plate is fixed inside the housing. An upright shaft is fixed on the support frame. A connecting rod is rotatably connected to the upright shaft. A reciprocating cam driven by a motor is rotatably mounted inside the housing. The end of the connecting rod away from the upright shaft is hinged to the cam.

[0016] Furthermore, a motor-driven lifting cam is rotatably mounted on the support frame. The edge of the lifting cam is provided with a wheel groove, and a guide wheel that mates with the wheel groove is provided above the lifting cam. A flat plate is provided above the support frame, and a wheel frame that is rotatably connected to the guide wheel is provided at the bottom of the flat plate.

[0017] Compared with the prior art, the present invention has at least the following beneficial effects:

[0018] Combining horizontal reciprocating vibration, the medicine bottle is placed on the support frame, supported by the folding plate unit. The top of the medicine bottle touches the first folding plate, and the medicine bottle is placed on the second support plate, so that the medicine bottle is tilted in the direction of vibration.

[0029] The present invention will be further illustrated below with reference to specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of the present invention. Furthermore, it should be understood that after reading the teachings of this invention, those skilled in the art can make various alterations or modifications to the present invention, and these equivalent forms also fall within the scope defined in this application.

[0030] Example 1

[0031] A shaking device for clinical drugs, such as Figure 1-7 As shown, the main structure of the oscillation device for clinical drugs includes a host unit at the bottom, and a vibration platform 21 driven by the host unit is provided above the host unit. The vibration mode of the vibration platform 21 includes left and right translation, so it belongs to reciprocating oscillation.

[0032] The shaking device used in this embodiment for clinical drugs mainly adjusts the constraint and placement posture of the medicine bottle. By tilting and laying the medicine bottle down, the mixing effect is optimized.

[0033] The vibration platform 21 is equipped with a fitting for confining the medicine bottle—a receiving groove 22. The receiving groove 22 has a rectangular groove structure and an open top. The receiving groove 22 is used to hold the medicine bottle.

[0034] The receiving groove 22 is equipped with a support frame fixed to the bottom of the groove. The support frame is made of metal or plastic sheet and adopts an integrally formed folded plate structure, including multiple continuously connected folded plate units. Each folded plate unit includes a first support plate 23 and a second support plate 24 that are vertically connected in an L-shape. Silicone pads can be placed on the top surfaces of the first and second folded plates. The bottom side of the first support plate 23 is perpendicularly connected to the bottom side of the second support plate 24, forming a set of folded plate units. The second support plate 24 forms a 15-degree angle with the vibration platform 21, so that the second support plate 24 supports the lying medicine bottle body at a small tilt angle. The top sides of the first support plate 23 and the top sides of the second support plate 24 of adjacent folded plate units are vertically connected to obtain continuous folded plate units.

[0035] The direction of the folding plate units is consistent with the horizontal reciprocating vibration direction of the vibration platform 21, that is, the folding plate units are connected in a horizontal equidistant array along the length of the track bar 9.

[0036] The medicine bottle is placed using the aforementioned folding plate unit with the bottle opening facing down and the bottom facing up, resting on the second support plate 24. One end of the bottle cap rests against the first support plate 23, providing an optimized support method. In this configuration, the medicine bottle is slightly inverted at a 15-degree angle, allowing the solution inside the bottle to slosh in the depth direction when the vibration platform 21 vibrates horizontally. This facilitates rapid mixing of different drugs, increases the fluidity and turbulence of the liquid inside the bottle, and improves the dissolution efficiency of poorly soluble drugs. Simultaneously, the optimized 15-degree angle ensures both thorough mixing in depth and collision and contact of the solutions within the bottle, promoting rapid drug dissolution.

[0037] Example 2

[0038] Based on the shaking device for clinical drugs shown in Example 1, such as Figure 1-7 As shown, to restrain the medicine bottle and prevent collisions, a horizontally extending limiting strip 25 is provided above the support frame. The limiting strip 25 is set in the receiving groove 22 and its position is adjustable relative to the receiving groove 22. The limiting strip 25 is set along the horizontal vibration direction, that is, the limiting strip 25 is set parallel to the side wall 2. The limiting strip 25 is cylindrical and its surface is covered with a flexible foam layer or silicone layer to better squeeze the bottle body and make gentle contact with the medicine bottle. Screws 26 are fixed at both ends of the limiting strip 25. A strip-shaped hole 28 is horizontally opened in the upper part of the groove wall of the receiving groove 22. The strip-shaped hole 28 is set perpendicular to the horizontal vibration direction of the vibration platform 21. The screw 26 passes through the strip-shaped hole 28 on the same side and is threadedly connected to a large nut 27. The large nut 27 is a knob design for easy operation. The large nut 27 fixes the limiting strip 25 in the receiving groove 22 by tightening it with the screw 26.

[0039] Based on the above structure, the spacing of the limiting strips 25 in the receiving groove 22 is adjustable, and they can be removed by removing the large nut 27 and tilting slightly, which allows for flexible use. When there are fewer medicine bottles, the limiting strips 25 can be fixed only on both sides of the medicine bottles. When the medicine bottles are full, the limiting strips 25 can be fixed on both sides of each row of medicine bottles, which effectively restrains the bottles from vibrating.

[0040] The opening of the receiving groove 22 is also provided with a baffle 29 that slides with it. The size of the baffle 29 is adapted to the opening. The two sides of the opening are provided with sliding grooves 30. The two sides of the baffle 29 are movably inserted into the sliding grooves 30. When the baffle 29 is inserted into the sliding grooves 30, the bottom surface of the baffle 29 contacts the bottom of the medicine bottle placed on the support frame. It cooperates with the first folding plate to constrain the two ends of the medicine bottle, so that the medicine bottle can better follow the vibration. The bottom surface of the baffle 29 is provided with a flexible pad, which can be a silicone layer, making the contact with the bottom of the bottle softer and buffering the impact during vibration.

[0041] The baffle 29 and the receiving tank 22 can be made into transparent structures to facilitate observation of the internal mixing and dissolution.

[0042] The reciprocating motor and the lifting motor are controlled independently, allowing for flexible selection of vibration modes.

[0045] A display screen and control buttons can be installed on the end plate 4 for convenient control of the device.

[0046] Reinforcing frames can be installed at both ends of the sidewall 2. The reinforcing frames are used to install end panels, and the shape of the reinforcing frames is adapted to the internal cross-section of the housing.

[0047] A vertical strip plate 5 is fixed to the middle of the side wall 2. The strip plate 5 is fixed to the side wall 2 by bolts. Modular installation of the support components is achieved based on the strip plate 5. Support rollers 6 and pressure rollers 7 are rotatably mounted on the inner end face of the strip plate 5. There are multiple support rollers 6 arranged horizontally side by side. The axis of the support rollers 6 is perpendicular to the strip plate 5 and the side wall 2. The axis of the pressure rollers 7 is parallel to the support rollers 6. Multiple pressure rollers 7 are arranged horizontally side by side above the support rollers 6, forming an upper and lower two-layer guide wheel 15 structure. In order to provide effective support, reasonable guidance, and save components, there are two pressure rollers 7, which are centered relative to the side wall 2.

[0048] The main unit is equipped with a support frame 8 with a horizontal reciprocating stroke. I-shaped rails 9 are fixed on both sides of the support frame 8 adjacent to the side wall 2. The top and bottom sides of the rails 9 are respectively provided with rail grooves 10. The top circumferential surface of the support roller 6 contacts and cooperates with the bottom of the lower rail groove 10 to support and guide the support frame 8. The bottom circumferential surface of the pressure roller 7 contacts and cooperates with the bottom of the upper rail groove 10 to provide auxiliary constraint on the reciprocating stroke of the support frame 8.

[0049] A downwardly extending vertical shaft 11 is fixed in the middle of one side of the support frame 8, and a connecting rod 12 is rotatably connected to the vertical shaft 11.

[0050] The main unit is equipped with a motor frame fixed at the bottom of the main unit. A reciprocating motor is installed below the motor frame. A reciprocating cam 13 driven by the reciprocating motor is rotatably connected to the motor frame. One protruding end of the reciprocating cam 13 is rotatably connected to the end of the connecting rod 12 away from the vertical shaft 11. The reciprocating cam 13 is driven to rotate by the reciprocating motor, thereby driving the reciprocating horizontal movement of the support frame 8.

[0051] Example 4

[0052] Based on the shaking device for clinical drugs shown in Example 1, such as Figure 1-7 As shown in the figure, this embodiment illustrates the reciprocating vibration of a vibration platform. A lifting cam 14 is rotatably mounted on the frame edge of the support frame 8 opposite to the vertical shaft 11. The axle of the lifting cam 14 is horizontally set, and the edge or outer side of the lifting cam 14 is provided with a wheel groove. A lifting motor is installed below the support frame 8, and the output shaft of the lifting motor is connected to the lifting cam 14 through a reducer to realize the rotation drive of the lifting cam 14.

[0053] The support frame 8 is provided with a sliding sleeve 19 near the four corners, through which the sleeves are inserted. The sliding sleeve 19 has a circular sliding hole in the center.

[0054] Above the support frame 8 is a flat plate 17 with a reciprocating lifting stroke. On the bottom surface of the flat plate 17, a vertically extending optical axis 18 is fixed at the position of the bushing. The optical axis 18 passes through the shaft hole of the bushing and slides up and down with the bushing. The lifting stroke of the flat plate 17 is guided by the optical axes 18 set at the four corners. A wheel frame is also provided below the flat plate 17. A guide wheel 15 is rotatably installed on the wheel frame. The guide wheel 15 cooperates with the wheel groove of the lifting cam 14. Based on the rotation of the lifting cam 14, the reciprocating vibration of the flat plate 17 is driven.

[0055] Based on the weight of the plate 17 and the vibration platform 21, the plate 17 can be automatically lowered and lifted upwards based on the cam. This is not limited to this example. Alternatively, a return spring can be installed between the optical axis 18 (or the plate 17) and the support frame 8. The return spring has an elastic force that causes the plate 17 to move downwards.

[0056] The top surface of the platform is fixed with support columns 20. In this example, there are two support columns 20, but the number is not limited to this example and can be other numbers. The machine plate 3 is provided with slotted holes at the positions corresponding to the support columns 20. The slotted holes have a margin in the horizontal reciprocating stroke relative to the support frame 8 to facilitate the left and right vibration of the support columns 20.

[0057] The top of the support column 20 is fixed with a vibration platform 21, which supports the target.
