Description

Technical Field

[0001] The present invention relates to the technical field of medicine mixing and dissolving, and in particular to a solid medicine mixing and dissolving device. Background Art

[0002] Solid dosage form dissolution involves a process of pharmaceutical research and formulation development that includes multiple steps and techniques. In this process, the following methods and factors are usually considered: First, choose the appropriate solvent: the choice of solvent should be determined based on the chemical properties of the solid drug, solubility and compatibility between the drug and the solvent. Commonly used solvents include water, alcohol, ether, glycerol, etc.

[0003] The second is heating dissolution: heating can increase the solubility of the solvent and the speed of molecular movement, thereby accelerating the dissolution rate. During operation, the solvent can be poured into a container, heated to the temperature at which the drug dissolves, and then the solid drug is added to the container and stirred to make it evenly dispersed.

[0004] The third is stirring dissolution: stirring can increase the contact area between the solute and the solvent, promote mass transfer, and accelerate the dissolution rate. The stirring speed and time should be adjusted according to the solubility of the solid drug and the characteristics of the solvent.

[0005] Fourth, solid dispersion technology: solid dispersion technology includes co-precipitation-vacuum drying method, solvent-spray drying method, anti-solvent co-precipitation method, etc.

[0006] The above methods are applicable to different drugs and carrier materials, and the appropriate method can be selected according to the characteristics and requirements of the drug.

[0007] In pharmaceutical research, regarding the dissolution and mixing of solid medicines, the traditional method is to add the solid medicines to a conical flask, and then have the experimenter manually shake it to accelerate the dissolution, and then perform the next step of mixing on the dissolved medicine liquid. This operation method is very inconvenient for the pharmaceutical research experiment process with frequent operations, the workload of the staff is large, and the efficiency of pharmaceutical experiments is low. At present, there are corresponding solid medicine dissolution and mixing devices for pharmaceutical research in the prior art. This device can improve the dissolution rate and mixing efficiency of solid medicines, replace manual shaking with mechanical shaking, reduce the work intensity of researchers, and screen solid medicines of different particle sizes during shaking.

[0008] After searching, it was found that a Chinese patent with publication number CN111266025B in the prior art discloses a solid medicine dissolving and mixing device for pharmaceutical research. The technical solution of this patent solves the problem in the traditional method that "the operation method of adding the solid medicine into a conical flask and then manually shaking by the experimenter to accelerate the dissolution is very inconvenient for the frequent operation process of pharmaceutical research experiments, increases the difficulty of work, and reduces the efficiency of pharmaceutical experiments". At the same time, the technical solution of this prior patent also solves the problem that "the dissolving and mixing equipment in the prior art dissolves the medicine first and then transfers it to the mixing device for stirring and mixing, which increases the number of experimental equipment and reduces the efficiency of pharmaceutical research experiments." In the disclosure of the above patent, its main structures are the medicine dissolving component and the medicine mixing component. The medicine dissolving component is achieved by setting two motors so that the rotating box can rotate in both horizontal and vertical planes. At the same time, a melting-aiding protrusion is set in the medicine tube, so that the solid medicine and the melting-aiding protrusion continuously collide with each other during the rotation of the medicine tube with the rotating box, thereby improving the dissolution efficiency of the solid medicine. The medicine mixing component is mainly composed of a mixing barrel and a stirring component. The stirring component is composed of a mixing plate, a rotating fan plate and a forward and reverse motor. The mixing plate moves up and down in the mixing barrel under the action of the forward and reverse motor and the threaded rod, and the medicine continuously falls through the through holes on the mixing plate. The rotating fan plate rotates in reverse during the movement of the mixing plate to mix various medicines.

[0009] Although the above-mentioned existing patent uses two motors to realize the rotation of the mixture of solid medicine and solvent in the dissolving component in two dimensions on the horizontal plane and the vertical plane, it only increases the rotation dimension of the solid medicine in the solvent. The solid medicine is equivalent to being dissolved only by rotating in the solvent, and the effect of improving its dissolution efficiency in the solvent is not significant; at the same time, the equipment separates the dissolution and mixing into two units, which increases the overall equipment manufacturing and use costs, and the operation is cumbersome, and the structural components of the mixing unit achieve mixing through stirring, and the mixing efficiency is not high.

[0028] Reference Figure 1-Figure 7 As shown, the following are preferred embodiments provided by the present invention.

[0029] Example 1: This example 1 provides a solution of a solid medicine mixing and dissolving device, see Figure 1-Figure 4 As shown, its structural design is as follows: the mixed dissolution device comprises a supporting platform 1, a transparent mixed dissolution body installed on the top of the supporting platform 1, and a driving component and other components.

[0030] Among them, in this embodiment, the mixing and dissolving body includes a spherical tank body 2 and a spherical tank body 3 disposed in the inner cavity of the spherical tank body 2. The spherical tank body 2 is placed on a concave support pad 4 fixedly mounted on the top surface of the support platform 1. The top surface of the concave support pad 4 is an arc-shaped concave surface matching the shape of the outer wall of the spherical tank body 2, which is used to ensure that the spherical tank body 2 performs stable rotation on the concave support pad 4. A mixing working chamber 5 for mixing medicines is formed between the outer wall of the spherical tank body 2 3 and the inner wall of the spherical tank body 2. The outer wall of the spherical tank body 2 is provided with an addition nozzle 6 close to the top of the spherical tank body 2 and connected to the inside of the mixing working chamber 5. Through the addition nozzle 6, it is convenient to add medicines to the mixing working chamber 5.

[0031] In addition, a connecting piece 7 with a circular tube shape and an opening at the top is fixedly installed on the top of the spherical tank body 2 3. One end of the connecting piece 7 is sealed and connected to the inside of the spherical tank body 2 3, and the other end of the connecting piece 7 is away from the top of the spherical tank body 1 2 and the spherical tank body 2 3. In this embodiment, on the one hand, the connecting piece 7 is designed to be circular tube-shaped and has an opening at the top. By using the opening, it is convenient to directly add the medicine into the inside of the spherical tank body 2 3, and it can achieve the function of a feeding port; on the other hand, the connecting piece 7 is tubular and fixedly connected to the top of the spherical tank body 2 3, so that it can be conveniently used as a connecting shaft to drive the spherical tank body 2 3 to rotate, and realize the connection between the transmission mechanism.

[0032] The top of the spherical tank body 1 2 is sealed and embedded with a bearing 8 (a roller bearing 8 is used in this embodiment), and the outer wall of the connecting piece 7 away from the top of the spherical tank body 2 3 is sealed and fixedly connected to the inner ring wall of the bearing 8. Such a structural design enables the spherical tank body 2 3 and the spherical tank body 1 2 to achieve relative rotation through the bearing 8. The wall surface of the spherical tank body 2 3 is sealed and installed with multiple discharge pipes 9 at intervals in the circumferential direction. The discharge pipes 9 can realize the function of discharging the liquid in the spherical tank body 2 3 on the one hand, and can also realize the function of rotating and stirring the mixed solution in the mixing working chamber 5 on the other hand.

[0033] The outlet end of the discharge pipe fitting 9 is equipped with an opening and closing control component. In this embodiment, the mechanical control resistance member used in the opening and closing control component includes two fixed substrate members 10, two telescopic return springs 11 and a blocking cap set 12. The two fixed substrate members 10 are symmetrically fixed on the outer wall of the outlet end of the discharge pipe fitting 9 according to the central axis of the discharge pipe fitting 9. The blocking cap set 12 is sealed and movably sleeved on the outlet end of the discharge pipe fitting 9, and the end of the blocking cap set 12 that is close to the outer wall of the discharge pipe is connected to the fixed substrate member 10 through the telescopic return spring 11. During the rotation of the spherical tank body 23, when its rotation speed is steadily increased, the centrifugal force generated by its rotation causes the telescopic return spring 11 to extend under the action of the centrifugal force, thereby realizing the separation of the blocking cap set 12 from the outlet end of the discharge pipe, realizing the opening of the outlet end of the discharge pipe, and realizing the discharge of the liquid in the spherical tank body 23 into the mixing studio. Alternatively, the opening and closing control component can also be equivalent to replacing the electromagnetic valve to realize the automatic opening and closing function of the discharge pipe fitting 9.

[0034] The outer wall of the spherical tank body 2 is installed with a discharge component that can discharge the liquid in the mixing working chamber 5. In this embodiment, the discharge component adopts a structural design that combines a discharge pipe 13 and a micro liquid pump 14. The inlet end of the micro liquid pump 14 is connected to the inner bottom end of the mixing working chamber 5 through a liquid guide pipe (not shown in the figure), and the liquid outlet end of the micro liquid pump 14 is connected to the outlet end of the discharge pipe 13. Through this design, it is convenient to discharge the mixed agent in the mixing working chamber 5 after completing the dissolution and mixing work.

[0035] In the above implementation scheme of the present embodiment, the driving assembly includes a driving motor 15 and a transmission mechanism fixedly mounted on the top of the supporting platform 1 and close to the mixed dissolution body, and the transmission mechanism includes a transmission shaft 16, a gear 17, a pulley 18, a pulley 2 19, a transmission belt 20 and an annular gear sleeve 21. Among them, one end of the transmission shaft 16 is connected to the output end of the driving motor 15, the gear 17 is fixedly sleeved on the outer wall of the transmission shaft 16, the pulley 18 is fixedly sleeved on the outer wall of the end of the transmission shaft 16 away from the output end of the driving motor 15, the pulley 2 19 is fixedly sleeved on the outer wall of the end of the connecting member 7 away from the spherical tank body 12, and the pulley 18 and the pulley 2 19 are connected by a transmission belt 20. The annular gear sleeve 21 is fixedly sleeved on the outer wall of the spherical tank body 12, and the annular gear sleeve 21 is meshed with the gear 17, so that the driving force of the driving motor 15 can be transmitted to the spherical tank body 12 to drive it to rotate.

[0036] In the above scheme of this embodiment, the inner wall of the spherical tank body 2 3 is also fixed with multiple dissolution-promoting protrusions 22 at intervals. The multiple dissolution-promoting protrusions 22 facilitate the contact friction between the solid medicine in the spherical tank body 2 3 and the inner wall of the spherical tank body 2 3, thereby improving the dissolution efficiency.

[0037] In addition, in the scheme of this embodiment, the discharge pipe fitting 9 is installed at an angle relative to the horizontal plane of the spherical tank body 2 3, and is distributed at staggered intervals along the outer wall surface of the spherical tank body 2 3. By utilizing its design with a certain inclination, the stirring and mixing function of the discharge pipe fitting 9 in the mixing working chamber 5 can be realized.

[0038] At the same time, in the implementation scheme of this embodiment, the connecting piece 7 is designed so that one end thereof extends to the interior of the spherical tank body 2 3, and a plurality of stirring blades 23 are designed to be spaced apart on the outer wall of the connecting piece 7 located inside the spherical tank body 2 3. By utilizing this structural design, the solution and the medicine in the spherical tank body 2 3 can be stirred and dissolved, thereby improving the dissolution efficiency.

[0039] In this embodiment of the present invention, the structural design of the support platform 1 adopts a box structure, which can not only provide a working platform for the dissolution and mixing of solid medicines, but also facilitate the storage of corresponding experimental consumables. At the same time, a pulley assembly 24 is installed at the bottom of the support platform 1, and a traction rod 25 is installed on one side wall of the support platform 1. Through the cooperation of the pulley assembly 24 and the traction rod 25, the movement and transfer of the device of the present invention are facilitated, thereby improving the convenience of the device.

[0040] Example 2: The difference between the implementation scheme of this Example 2 and the implementation scheme of Example 1 is: Figure 5-Figure 6 As shown, in this embodiment 2, the driving motor 15 is fixedly suspended and installed directly above the mixed dissolution body through the mounting support frame 30 installed on the top surface of the supporting platform 1, and one end of the connecting piece 7 extending out of the top of the spherical tank body 2 3 passes through the bearing (not shown in the figure) on the mounting support frame 30 and is fixedly connected to the output end of the driving motor 15, and the transmission shaft 16 is longitudinally installed between the mounting support frame 30 and the top surface of the supporting platform 1, and the two ends of the transmission shaft 16 are respectively connected to the top surface of the supporting platform 1 and the bottom of the mounting support frame 30 for rotation and movement. And a feeding pipe 26 is designed on the side wall of the connecting piece 7 near the top of the spherical tank body 2 3. The implementation scheme of this embodiment 2 adopts different implementation schemes to achieve the same effect of the solution of embodiment 1.

[0041] Example 3: The solution of this Example 2 is based on Example 2. The difference between this Example 2 and the solution of Example 2 is that: in this example, see Figure 7As shown, the support platform 1 is designed as a plate frame structure. The support platform 1 in this embodiment includes a bottom plate 27, a top plate 28 and four telescopic support columns 29. The four telescopic support columns 29 are respectively installed at the four corners of the top surface of the bottom plate 27. The top of the telescopic support column 29 is fixedly connected to the bottom surface of the top plate 28. The support platform 1 in this embodiment 3 can facilitate the adjustment of the height of the support platform 1 according to work requirements during the dissolution and mixing of solid medicines through the design of the telescopic support column 29 in the plate frame structure, thereby improving the convenience of operation during the work process.

[0042] Working principle: When the device of the present invention is used to dissolve and mix solid medicines, the solid medicines and the solvent are first added into the spherical tank body 2 3 through the opening of the connecting piece 7, and the transmission shaft 16 is driven to rotate by the operation of the driving motor 15, thereby driving the pulley 18 to rotate. Through the rotation of the pulley 18, the transmission belt 20 drives the pulley 2 19 to rotate, thereby driving the connecting piece 7 to rotate, and realizing the rotational movement of the spherical tank body 2 3 fixedly connected to the connecting piece 7, so as to facilitate the rotational dissolution of the solid medicines in the spherical tank body 2 3 and improve the dissolution efficiency of the solid medicines in the spherical tank body 2 3; at the same time, under the operation of the driving motor 15, the driving force of the driving motor 15 can be transmitted to the spherical tank body 2 to make it rotate, by using the gear 17 designed and installed on the transmission shaft 16 and the annular gear sleeve 21 installed on the outer wall of the spherical tank body 2 and meshing with the gear 17, so as to realize the rotational mixing of the medicines in the mixing working chamber 5. In the device of the present invention, the rotational movement of the two rotating working units (dissolving unit and mixing unit) is realized by only one driving motor 15, which saves the equipment use cost of the solid medicine dissolving and mixing work and improves the work efficiency; at the same time, the scheme of the present invention designs the internal chamber structure of the mixed dissolving body as a spherical chamber. According to the spherical chamber, due to its unique spherical structure, it has a relatively large effective working volume, which can increase the volume of the dissolving and mixing work; and the designed spherical chamber has the same stirring force and direction in all directions, and it is symmetrical in mixing, and the mixing effect is Better; in addition, the inner cavity of the spherical tank body 2 3 of the mixed dissolution body of the present invention serves as a dissolution working chamber, and the chamber formed between the inner wall of the spherical tank body 2 and the outer wall of the spherical tank body 2 3 serves as a mixing working chamber 5. The inner cavity of the spherical tank body 2 3 and the mixing working chamber 5 are controllably connected through a discharge pipe 9, so that the equipment for the two operating processes of mixing and dissolving of the mixed dissolution is simplified, saving the cost of equipment use. Compared with the prior art in which two relatively independent operating units are required for two operating processes, it is also more convenient in operation, reduces workload, and improves work efficiency.
