Description

Technical Field

[0001] This invention relates to the field of drug solution mixing technology, specifically to an automated quantitative drug solution mixing device. Background Technology

[0002] Liquid pharmaceutical preparations refer to pharmaceutical preparations in liquid form, prepared by dispersing drugs in a suitable dispersion medium. They can be taken internally or applied externally. The drug in a liquid pharmaceutical preparation can be dispersed in the medium in a molecular or particulate state, thus forming a homogeneous or heterogeneous liquid pharmaceutical preparation. The degree of drug particle dispersion in a liquid pharmaceutical preparation is closely related to its efficacy, stability, and toxicity. Different dispersion states of liquid pharmaceutical preparations require different preparation methods.

[0003] Referring to the patent application with publication number CN218012169U, an automatic drug solution mixing and proportioning device is described, specifically an automatic drug solution mixing and proportioning device, including a top cover that covers each other and a mixing cylinder. The top cover is provided with an electric stirring mechanism that extends into the cylinder, and the outer wall of the cylinder is provided with scale markings. The electric driving mechanism includes a drive motor and a stirring element that is shaft-connected to the drive motor. The stirring element extends into the cylinder and rotates under the drive of the drive motor. The top cover is provided with several through holes that communicate with the interior of the cylinder.

[0004] Currently, when preparing the medicine solution, the concentrated medicine solution needs to be poured together with water and mixed in the specified ratio to complete the preparation. However, the mixing process requires manual or electric stirring rods. In places without electricity, a large amount of manpower is needed for stirring, which is inefficient. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides an automated quantitative mixing device for dispensing and mixing pharmaceutical solutions, thereby solving the aforementioned problems.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solution: an automated quantitative proportioning and mixing device for medicine, comprising a mixing tank, a top cover threadedly connected to the top of the mixing tank, an inlet pipe fixedly connected to the top of the top cover, and a diversion mixing mechanism provided inside the mixing tank;

[0007] The flow splitting and mixing mechanism includes:

[0008] The fixing plate is a circular disc structure. The outer wall of the fixing plate is rotatably connected to the inner wall of the mixing tank. A circular hole is opened on the inner wall of the fixing plate. A bottom plate is fixedly connected to the bottom of the inner wall of the mixing tank. The fixing plate is used to hold the mixture and make it gradually flow down.

[0009] The threaded rod is a threaded rod-shaped structure. One end of the threaded rod is fixedly connected to the top of the base plate. An internal threaded sleeve is threadedly connected to the outer wall of the threaded rod. A connecting rod is fixedly connected to the outer wall of the internal threaded sleeve.

[0011] Preferably, the inner wall of the skateboard is in contact with a scraper, and the bottom of the scraper is slidably connected to the top of the base plate through a groove, thereby limiting the scraper and preventing it from detaching from the base plate.

[0012] Preferably, a semi-circular block is fixedly connected to the top of the scraper, a semi-circular groove is formed on the inner wall of the semi-circular block, a separation hole is formed on the inner wall of the hinge rod, a baffle is fixedly connected to the top of the scraper, and a separation mechanism is provided inside the mixing tank.

[0013] Preferably, the slide plate is magnetic, the scraper is magnetic, and the magnetic poles on opposite sides of the slide plate and the scraper are attracted to each other, thereby preventing the scraper from detaching from the slide plate.

[0014] Preferably, the separation mechanism includes a fixed column, one end of which is fixedly connected to the top of the hollow buoyancy plate, and the other end of which is fixedly connected to a magnetic block A. The top of the magnetic block A contacts a planar bearing, the top of the planar bearing is rotatably connected to a fixed ring, and the top of the fixed ring is rotatably connected to another planar bearing. The top of the other planar bearing contacts a magnetic block B, thereby causing them to magnetically attract each other.

[0015] Preferably, a telescopic rod is fixedly connected to the top of the magnetic block B, a ring is fixedly connected to the top of the telescopic rod, a long rod is fixedly connected to the inner wall of the ring, a rotating sleeve B is fixedly connected to one end of the long rod, the inner wall of the rotating sleeve B is slidably connected to the outer wall of the threaded rod, and the top of the rotating sleeve B is fixedly connected to the fixed plate.

[0016] Preferably, the inner wall of the mixing tank is slidably connected to a connecting plate via a sliding groove, the outer wall of the connecting plate is fixedly connected to the outer wall of the fixing ring, a lever plate is fixedly connected to the bottom of the connecting plate, the inner wall of the lever plate is provided with a square groove, and the magnetic poles of the opposite sides of the magnetic block B and magnetic block A are attracted to each other, thereby making them magnetically attracted to each other.

[0017] This invention provides an automated quantitative mixing device for dispensing and mixing pharmaceutical solutions, which has the following advantages:

[0018] 1. This invention, through the setting of a diversion and mixing mechanism, pours the medicine and water into the inlet pipe, and then into the fixed plate in the mixing tank. The medicine and water are evenly filtered through the evenly distributed circular holes on the surface of the fixed plate, and then sprinkled onto the bottom plate at the bottom of the inner wall of the mixing tank. The medicine and water are splashed together by falling from a height, thereby mixing them together and further improving the mixing efficiency of the medicine and water. The numerous circular holes also ensure that the medicine and water fall evenly, ensuring the uniformity of the splash range and limiting the falling speed of the mixture. In a simple, quick and convenient way, the medicine and water are automatically and initially mixed when placed.

[0019] 2. This invention, by setting up a diversion and mixing mechanism, enables the hinged rod, which is hinged to the outer wall of the threaded rod, to rotate and rise synchronously, automatically stirring the mixture in real time. This continuously mixes and blends the medicine and water, avoiding the problem of excessive mixing efficiency caused by pouring in a large amount of medicine and water. It ensures a highly efficient mixing effect and fully automatic mixing function without manual intervention or electricity, thus achieving automatic, convenient, and uniform mixing in outdoor, vehicle, and various locations without power.

[0020] 3. This invention, through the setting of a diversion and mixing mechanism, when the hinge rod is driven to rotate, the hinge rod will drive the slide plate and scraper to rotate synchronously through the rotating ball and rotating sleeve A. Thus, the scraper continuously scrapes and turns the bottom layer of the mixture on the bottom plate, fully peeling off the solidified and adhered substances that gradually settle on the bottom of the inner wall of the mixing tank and pushing them into the mixture. At the same time, the mixture can be separated by the separation holes opened on the inner wall of the hinge rod and scraper and the semi-circular groove on the semi-circular block when they rotate. The mixture is continuously diverted through the separation holes and semi-circular groove, so that the precipitated and adhered substances in the mixture and the solidified substances that are scraped and floated by the scraper are separated and broken up. This further improves the breaking and dispersing effect of the precipitated substances in the mixture and prevents the problem of the drug-liquid ratio in the mixture from being unbalanced due to adhesion to the bottom plate.

[0021] 4. This invention, by setting up a diversion and mixing mechanism, uses a sliding plate that slides on the outer wall of the scraper to peel off the solidified material adhering to the surface of the cleaning plate. At the same time, as the sliding plate slides on the scraper surface, it is lifted and falls on the semi-circular block. The sliding plate, through the rotating sleeve A and the rotating ball, causes the hinge rod to vibrate once. Each time the sliding plate passes the semi-circular block, the entire system vibrates. The vibration and rotation of the hinge rod improve the mixing effect of the liquid and also shake off the adhering material on the hinge rod, ensuring that the hinge rod, sliding plate, and scraper are as clean as possible. This reduces the imbalance of the drug solution mixing ratio caused by the adhering material, which would affect the efficacy of the finished drug solution.

[0022] 5. This invention, by setting up a separation mechanism, uses the rotation of the telescopic rod to drive the ring and the long rod to rotate, causing the rotating sleeve B to rotate synchronously and controlling the fixed plate to rotate synchronously as well. This allows the mixture accumulated on the fixed plate to fall through the circular hole, so that the mixture that was originally unevenly mixed on the fixed plate 301 can be more evenly sprinkled downwards through the rotation of the circular hole 302. Thus, when the medicine and water are poured onto the fixed plate at the same time, the uniformity of its falling through the circular hole can be guaranteed without pre-mixing and stirring.

[0023] 6. This invention, by setting up a separation mechanism, enables relative movement between the fixed ring, the hollow buoyancy plate, the hinge rod, magnetic block A, magnetic block B, the telescopic rod, and the mixed liquid inside the mixing tank that is being rotated and mixed. When the mixed liquid is fully rotated, it will continuously interact with the dial plate. Because the dial plate is fixed by the connecting plate, the dial plate moves relative to the mixed liquid, thus achieving the dialing effect. Furthermore, the mixed liquid is continuously diverted through the square groove due to the impact of rotation, ensuring that the mixed liquid inside the mixing tank is fully and evenly distributed and dialed. This avoids the problem of losing the original dialing effect when the mixed liquid rotates synchronously with the hinge rod, thus ensuring the high efficiency of long-term mixing.

Detailed Implementation

[0038] Example 1:

[0039] Please see Figure 1-3 The present invention provides a technical solution: an automated quantitative proportioning and mixing device for medicine, including a mixing tank 2, a top cover 1 threadedly connected to the top of the mixing tank 2, an inlet pipe 5 fixedly connected to the top of the top cover 1, and a diversion mixing mechanism 3 provided inside the mixing tank 2;

[0040] The diversion and mixing mechanism 3 includes:

[0041] The fixing plate 301 is a circular disc structure. The outer wall of the fixing plate 301 is rotatably connected to the inner wall of the mixing tank 2. A circular hole 302 is opened on the inner wall of the fixing plate 301. A bottom plate 303 is fixedly connected to the bottom of the inner wall of the mixing tank 2. The fixing plate 301 is used to hold the mixture and make it gradually flow down.

[0042] The medicine and water are poured into the inlet pipe 5 and then into the fixed plate 301 in the mixing tank 2. The medicine and water are filtered evenly through the evenly distributed circular holes 302 on the surface of the fixed plate 301 and then sprinkled onto the bottom plate 303 at the bottom of the inner wall of the mixing tank 2. The medicine and water are splashed together by falling from a height, thereby mixing them and further improving the mixing efficiency of the medicine and water. The numerous circular holes 302 also ensure that the medicine and water fall evenly, ensuring the uniformity of the splash range and limiting the falling speed of the mixture. In a simple, quick and convenient way, the medicine and water are automatically mixed initially when placed.

[0043] Example 2:

[0044] Please see Figure 1-9 Based on Embodiment 1, the present invention provides a technical solution: the diversion and mixing mechanism 3 includes:

[0045] A threaded rod 304 is a threaded rod-shaped structure. One end of the threaded rod 304 is fixedly connected to the top of the base plate 303. An internal threaded sleeve 305 is threadedly connected to the outer wall of the threaded rod 304. A connecting rod 306 is fixedly connected to the outer wall of the internal threaded sleeve 305. A hollow buoyancy plate 307 is fixedly connected to one end of the connecting rod 306. The threaded rod 304 is used to rotate the internal threaded sleeve 305.

[0046] The outer wall of the internal threaded sleeve 305 is hinged to a hinge rod 308. One end of the hinge rod 308 is fixedly connected to a rotating ball 310. The outer wall of the rotating ball 310 is rotatably connected to a rotating sleeve A311. The outer wall of the rotating sleeve A311 is fixedly connected to a sliding plate 312.

[0047] The inner wall of the slide plate 312 is in contact with a scraper 313, and the bottom of the scraper 313 is slidably connected to the top of the base plate 303 through a groove.

[0048] A semi-circular block 314 is fixedly connected to the top of the scraper 313. A semi-circular groove 315 is opened on the inner wall of the semi-circular block 314. A separation hole 309 is opened on the inner wall of the hinge rod 308. A baffle 316 is fixedly connected to the top of the scraper 313. A separation mechanism 4 is provided inside the mixing tank 2.

[0049] The slide plate 312 is magnetic, the scraper 313 is magnetic, and the magnetic poles of the opposite sides of the slide plate 312 and the scraper 313 are attracted to each other.

[0050] As the mixture gradually accumulates at the top of the bottom plate 303, the water level rises, which in turn pushes the hollow buoyancy plate 307 to slide and rise on the inner wall of the mixing tank 2 through its own buoyancy. The rise of the hollow buoyancy plate 307 drives the internal threaded sleeve 305 to rise synchronously through the connecting rod 306. When the internal threaded sleeve 305 rises, it rotates and slides on the outer wall of the threaded rod 304 through the threaded connection between the inner wall of the internal threaded sleeve 305 and the outer wall of the threaded rod 304. Because the thread helix angle between the internal threaded sleeve 305 and the threaded rod 304 is greater than 45 degrees, the friction is very small, which enables rotation and rise.

[0051] While the outer wall of the threaded rod 304 rotates and rises, the inner threaded sleeve 305 drives the connecting rod 306 and the hollow buoyancy plate 307 to rotate and rise synchronously. This enables the hinged rod 308, which is hinged to the outer wall of the inner threaded sleeve 305, to rotate and rise synchronously, thus automatically stirring the mixture in real time. This continuously mixes and blends the medicine and water, avoiding the problem of excessive mixing efficiency caused by pouring in a large amount of medicine and water. This ensures a highly efficient mixing effect and fully automatic mixing function without manual intervention or electricity, enabling automatic, convenient, and uniform mixing in outdoor, vehicle, and various locations without power.

[0052] As the hinge rod 308 is driven to rotate, it drives the slide plate 312 and scraper 313 to rotate synchronously through the rotating ball 310 and rotating sleeve A311. The scraper 313 continuously scrapes and flips the bottom layer of the mixture on the bottom plate 303, fully peeling off the solidified and adhered substances that gradually settle on the bottom of the inner wall of the mixing tank 2 and pushing them into the mixture. At the same time, the mixture can be separated by the separation hole 309 on the inner wall of the hinge rod 308 and the semi-circular groove 315 on the semi-circular block 314 when the hinge rod 308 and the scraper 313 rotate. The mixture is continuously diverted through the separation hole 309 and the semi-circular groove 315, so that the sediment in the mixture and the solidified substances that are scraped and floated by the scraper 313 are separated and broken. This further improves the breaking and dispersing effect of sediment in the mixture and prevents the problem of imbalance of the drug ratio in the mixture due to adhesion to the bottom plate 303.

[0053] Simultaneously, as the water level rises, the hollow buoyancy plate 307 and the internal threaded sleeve 305 also rise, pulling one end of the hinge rod 308 upwards. Since the length of the hinge rod 308 is fixed, the other end of the hinge rod 308 pulls the rotating ball 310, the rotating sleeve A311, and the sliding plate 312 to slide on the outer wall of the scraper 313. At the same time, the sliding plate 312 and the scraper 313 maintain magnetic attraction, so the sliding plate 312 will not detach from the outer wall of the scraper 313. Furthermore, the sliding of the sliding plate 312 on the outer wall of the scraper 313 will peel off the solidified material adhering to the surface of the cleaning base plate 303 scraped by the scraper 313. Also, as the sliding plate 312 slides on the surface of the scraper 313, it will be lifted and fall onto the semi-circular block 314. Because the semi-circular block... The top of block 314 is an arched arc shape, so the friction of the slide plate 312 is small when it passes the semicircular block 314. It is lifted by the semicircular block 314 and then falls down again by the magnetic attraction between the slide plate 312 and the scraper 313 to continue sliding. The slide plate 312 will drive the hinge rod 308 to vibrate once by rotating sleeve A311 and rotating ball 310. The slide plate 312 will vibrate once every time it passes the semicircular block 314. The vibration and rotation of the hinge rod 308 will improve the mixing effect of the mixture and also shake off the adhering substances on the hinge rod 308, so as to keep the hinge rod 308, slide plate 312 and scraper 313 as clean as possible and reduce the imbalance of the drug mixture ratio caused by the adhesion of the substances, which will affect the efficacy of the drug mixture.

[0054] Example 3:

[0055] Please see Figure 1-13 Based on Embodiments 1 and 2, the present invention provides a technical solution: the separation mechanism 4 includes a fixed column 401, one end of which is fixedly connected to the top of the hollow buoyancy plate 307, and the other end of which is fixedly connected to a magnetic block A404. The top of the magnetic block A404 contacts a planar bearing 402, and the top of the planar bearing 402 is rotatably connected to a fixed ring 403. The top of the fixed ring 403 is rotatably connected to another planar bearing 402, and the top of the other planar bearing 402 contacts a magnetic block B405.

[0056] A telescopic rod 406 is fixedly connected to the top of the magnetic block B405. A ring 407 is fixedly connected to the top of the telescopic rod 406. A long rod 408 is fixedly connected to the inner wall of the ring 407. A rotating sleeve B409 is fixedly connected to one end of the long rod 408. The inner wall of the rotating sleeve B409 is slidably connected to the outer wall of the threaded rod 304. The top of the rotating sleeve B409 is fixedly connected to the fixing plate 301.

[0057] The inner wall of the mixing tank 2 is slidably connected to a connecting plate 410 via a sliding groove. The outer wall of the connecting plate 410 is fixedly connected to the outer wall of the fixing ring 403. A lever plate 411 is fixedly connected to the bottom of the connecting plate 410. A square groove 412 is opened on the inner wall of the lever plate 411. The magnetic properties of the opposite sides of the magnetic block B405 and the magnetic block A404 are opposite poles attracting each other.

[0058] As the hollow buoyancy plate 307 rises, it also drives the magnetic block A404 to rotate via the top fixed column 401. Magnetic block A404 is magnetically attracted to magnetic block B405, thus synchronously driving the telescopic rod 406 to rotate and move. Simultaneously, the rising and rotating of the hollow buoyancy plate 307 also pushes the fixed column 401 upwards. The rising of the fixed column 401 synchronously pushes the magnetic block A404 upwards. Magnetic block A404, in turn, pushes magnetic block B405 and the telescopic rod 406 upwards synchronously via the fixed ring 403 and the plane bearing 402. This completes the synchronous rotation of the telescopic rod 406 as it rises, causing the telescopic rod 406 to retract, providing space between the fixed column 401 and the hollow buoyancy plate 307. The rising space of the buoyancy plate 307, and the rotation of the telescopic rod 406 drives the ring 407 and the long rod 408 to start rotating, so that the rotating sleeve B409 rotates synchronously and the fixed connection with the fixed plate 301 controls the fixed plate 301 to also rotate synchronously. When the mixture accumulated on the fixed plate 301 falls through the circular hole 302, the mixture that was originally unevenly mixed on the fixed plate 301 can also be more evenly sprinkled downwards through the rotation of the circular hole 302. Thus, when the medicine and water are poured onto the fixed plate 301 at the same time, the uniformity of its falling through the circular hole 302 can be guaranteed without pre-mixing and stirring.

[0059] Furthermore, during the upward rotation of magnetic block A404, magnetic block B405 is pushed upward via the fixing ring 403 and the plane bearing 402. The fixing ring 403 is fixed by the connecting plate 410, which slides along the inner wall of the mixing tank 2 via a groove. The connecting plate 410 only moves vertically up and down within the mixing tank 2. Therefore, while magnetic block B405 and magnetic block A404 rotate, the fixing ring 403 cannot rotate but can move up and down, ensuring the normal lifting and lowering of magnetic block B405 and the telescopic rod 406. Because the fixing ring 403 cannot rotate, it connects with the hollow buoyancy plate 307, the hinge rod 308, and magnetic block A404. The magnetic block B405, the telescopic rod 406, and the mixed liquid inside the mixing tank 2 move relative to each other. When the mixed liquid is fully rotated, it will continuously interact with the dial plate 411. Since the dial plate 411 is fixed by the connecting plate 410, the dial plate 411 moves relative to the mixed liquid, thus achieving the dialing effect. Furthermore, the mixed liquid is continuously diverted through the square groove 412 due to the impact of rotation, which fully and evenly distributes the mixed liquid inside the mixing tank 2. This avoids the problem that the original impact dialing effect of the mixed liquid will be lost once it rotates synchronously with the hinge rod 308 after being rotated, thus ensuring the high efficiency of long-term mixing.

[0060] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
