[0073] The following description is intended to disclose the invention and enable those skilled in the art to implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.
[0074] As shown in Figures 1 to 12, a grinding and dissolving device for testing solid pharmaceuticals includes: a tank 1, with a frame 2 fixedly connected to the lower side wall of the tank 1;
[0075] The cap 3 is snapped onto the pre-set feed inlet at the top of the tank body 1;
[0076] The discharge cylinder 5 is fixedly connected to the bottom of the tank body 1;
[0077] Grinding and dissolving assembly, which is installed inside tank 1;
[0078] During the grinding process of solid medicines in this device, the grinding and dissolving component first grinds and pulverizes the solid medicines put into the tank 1, and then dissolves the solid medicine powder after grinding and pulverizing. The dissolved medicines after grinding and pulverizing are discharged from the discharge cylinder 5.
[0079] Currently, in the process of grinding and dissolving pharmaceuticals, existing technologies involve each step being performed separately, and water dissolution is done manually, resulting in cumbersome procedures and low testing efficiency. Furthermore, the dissolved pharmaceuticals can be difficult to discharge. The proposed embodiment solves these problems. The specific implementation is as follows: First, solid pharmaceuticals are fed into tank 1 through the inlet at the top of tank 1. Then, the cap 3 is closed. Next, the grinding and dissolving assembly grinds and pulverizes the solid pharmaceuticals in tank 1. After grinding and pulverization, the powdered pharmaceuticals are dissolved. The ground and dissolved pharmaceuticals are discharged from the discharge cylinder 5. By having the pharmaceuticals pulverized and dissolved within tank 1, the need for transferring the pulverized pharmaceuticals to a dissolving instrument is eliminated. Dissolving within the dissolving instrument reduces operational steps and time, thereby improving the efficiency of pharmaceutical testing.
[0080] When the amount of drug to be tested is small, the drug can be directly ground and pulverized in the tank 1 first, and then the ground drug can be stirred and dissolved by the grinding and dissolving component. This helps to avoid wasting time due to the process of switching between grinding and dissolving. Secondly, when the amount of drug to be tested is small, the grinding and dissolving of the drug can be integrated into one process. That is, after the device has finished working, the solution discharged from the discharge cylinder 5 is the drug solution after grinding and dissolving. Then the drug solution can be directly tested, simplifying the process.
[0081] It should be further explained that the cap 3 is used to seal the feed inlet, which helps to prevent the drug powder from flying out of the feed inlet during the grinding and pulverization of solid drugs, thus avoiding waste and affecting the accuracy of the test values.
[0082] As one embodiment of the present invention, the grinding and dissolving assembly includes a grinding body 4 and a driving mechanism. The grinding body 4 is rotatably connected to the inside of the tank 1. The driving mechanism is located at the top of the tank 1. The grinding body 4 is driven by the driving mechanism. An inner cavity 10 is opened inside the grinding body 4. A water supply mechanism is provided at the top of the grinding body 4 to supply water to the inner cavity 10. A grinding strip 21 is fixedly connected to the bottom surface of the grinding body 4.
[0083] During operation, after the solid medicine is placed into the tank 1, it falls to the bottom. The drive mechanism is then activated, causing the grinding body 4 and grinding strips 21 to rotate and grind the solid medicine. During the grinding process, the heat generated by the grinding and friction between the grinding body 4 and the medicine raises the temperature of the bottom surface of the grinding body 4. Water is supplied to the inner cavity 10 through the water supply mechanism to cool the grinding body 4, which helps to reduce the impact of temperature on the chemical components in the medicine and thus avoids inaccurate monitoring values. After the solid medicine is ground, the water supply mechanism supplies water to the tank 1 to dissolve the ground medicine powder. During this process, the water supply mechanism also flushes the inner wall of the tank 1, which helps to prevent the ground medicine powder from sticking to the inner wall of the tank 1. This helps to prevent the reduction of solute due to the medicine powder sticking to the inner wall of the tank 1, which would reduce the amount of medicine powder dissolved in the water and cause errors in the dissolution ratio. Finally, the dissolved medicine solution to be tested is discharged through the discharge cylinder 5.
[0084] As one embodiment of the present invention, the driving mechanism includes a fixed frame 6 and a transmission component. The transmission component includes a first gear 8 and a second gear 9. The fixed frame 6 is fixedly connected to the inner side wall of the top of the tank 1. A first motor 7 is fixedly connected to the top of the fixed frame 6. The rotating shaft of the first motor 7 passes through the bottom surface of the fixed frame 6 and is fixedly connected to the first gear 8. The second gear 9 is fixedly connected to the top of the grinding body 4. The first gear 8 and the second gear 9 mesh with each other.
[0085] When in operation, motor 7 is started, and motor 7 drives gear 9 and grinding body 4 to rotate through gear 8, so that grinding body 4 can crush and grind solid drug particles.
[0086] As one embodiment of the present invention, the water supply mechanism includes a cylindrical pipe 11 and a water tank 17. The water tank 17 is fixedly connected to the top of the tank body 1. A water pump 18 is fixedly connected to the top of the water tank 17. A solenoid valve 16 is fixedly connected to the side wall of the water tank 17.
[0087] The cylindrical tube 11 is rotatably connected to the top of the grinding body 4. The inlet pipe 12 and the return pipe 13 are fixedly connected inside the cylindrical tube 11. The inlet pipe 12 and the return pipe 13 both pass through the bottom of the cylindrical tube 11 and are placed in the inner cavity 10. The bottom of the return pipe 13 is lower than the bottom of the inlet pipe 12. The top of the inlet pipe 12 is fixedly connected to the first pipe body 14. The first pipe body 14 passes through the side wall of the cylindrical tube 11 and is fixedly connected to the outlet of the water pump 18. The top of the return pipe 13 is fixedly connected to the second pipe body 15. The second pipe body 15 passes through the side wall of the cylindrical tube 11 and is fixedly connected to the solenoid valve 16.
[0088] A water spray frame 19 is fixedly connected to the upper part of the grinding body 4. The water spray frame 19 is connected to the inner cavity 10. Multiple water spray heads 20 are fixedly connected to the water spray frame 19. A pressure valve is fixedly connected inside the water spray head 20.
[0089] During operation, before the grinding body 4 rotates, the solenoid valve 16 is opened, and the water pump 18 is started. The water pump 18 pumps water from the water tank 17 into the inner cavity 10 through the first pipe 14 and the inlet pipe 12. The water in the inner cavity 10 flows back into the water tank 17 through the return pipe 13 and the second pipe 15. This helps to cool the grinding body 4 during the grinding and pulverizing process. After the medicine is ground and pulverized, the solenoid valve 16 is closed, and the water pump 18 continues to pump water into the inner cavity 10. When the water pressure in the inner cavity 10 exceeds the pressure preset value of the one-way valve in the spray head 20, the spray head 20 sprays water into the tank 1. This helps to dissolve the ground and pulverized medicine particles and washes the medicine powder particles adsorbed on the inner wall of the tank 1 to the bottom of the tank 1. During the spraying process of the spray head 20, the grinding body 4 continues to rotate, and the grinding strips 21 at the bottom of the grinding body 4 also help to stir the medicine powder and water, which helps to improve the dissolution efficiency of the medicine powder.
[0090] The pressure valve inside the spray head 20 has a preset pressure value. When the water pressure in the inner cavity 10 is higher than the preset pressure value, the pressure valve opens; otherwise, the pressure valve closes. This technology is existing technology and will not be disclosed in detail here.
[0091] In one embodiment of the present invention, a discharge mechanism is provided inside the discharge cylinder 5. The discharge mechanism includes two discharge ports 501 and a rotating column 23. The two discharge ports 501 are symmetrically opened on the bottom side wall of the discharge cylinder 5. The rotating column 23 is rotatably connected inside the discharge cylinder 5. A propeller 25 is fixedly connected to the side wall of the rotating column 23. A sealing plate 24 is fixedly connected to the top of the propeller 25. The sealing plate 24 abuts against the inner wall of the end of the discharge cylinder 5. An insertion groove 26 is opened at the top of the rotating column 23. A friction pad 27 is fixedly connected to the bottom of the insertion groove 26. A cylindrical rod 22 is inserted into the insertion groove 26. The upper part of the cylindrical rod 22 is fixedly connected to the inner bottom surface of the grinding body 4. A friction pad 28 is fixedly connected to the bottom of the cylindrical rod 22. A top support is provided at the lower part of the rotating column 23. The top support is used to control the lifting and lowering of the rotating column 23.
[0092] A controller 38 and a timer 39 are fixedly connected to the top side wall of tank 1;
[0093] During operation, as the grinding body 4 rotates to grind and pulverize solid medicines and stir the medicine powder, the top support prevents the friction pad 27 at the top of the propeller 25 from contacting the friction pad 28 at the bottom of the cylindrical rod 22. The sealing plate 24 seals the top of the discharge cylinder 5, which helps prevent the medicine powder or dissolved medicine from flowing out of the discharge cylinder 5. After the medicine dissolves, during the discharge process, the grinding body 4 continues to rotate, and the top support pushes the rotating column 23 upward. The rotating column 23 drives the sealing plate 24 upward. As shown in Figure 11, the sealing plate 24... The bottom is higher than the bottom of the discharge cylinder 5, which facilitates the discharge of the medicine solution in the tank 1. At the same time, as the top holding member pushes the rotating column 23 upward, the rotating column 23 drives the sealing plate 24 upward. During this process, the friction pad 1 27 and the friction pad 28 come into contact. Under the rotation of the grinding body 4, the cylindrical rod 22 drives the rotating column 23 and the propeller 25 to rotate. The rotation of the propeller 25 is beneficial for both discharge and stirring of the medicine solution during the discharge process, which helps to further improve the uniformity of the medicine powder in the water.
[0094] In practice, a plug can be added to the discharge port 501. By closing the plug, the dissolved medicine can be stirred again in the discharge cylinder 5 to further promote the dissolution of the medicine.
[0095] As one embodiment of the present invention, the top support includes a base 29, a spring 30 and a magnet 31. The base 29 is fixedly connected to the bottom of the discharge cylinder 5, the spring 30 is sleeved on the bottom of the rotating column 23, and the top of the spring 30 is fixedly connected to the bottom surface of the discharge cylinder 5. The magnet 31 is fixedly connected to the bottom surface of the rotating column 23, and an electromagnet 32 is fixedly connected to the bottom surface of the base 29.
[0096] During operation, when the solid medicine needs to be discharged after being ground, crushed and dissolved, the electromagnet 32 can be activated. The opposite magnetic poles of the electromagnet 32 and the magnet block 31 are the same. According to the principle of like poles repulsion, the electromagnet 32 will push the magnet block 31 upward, and the magnet block 31 will push the rotating column 23 upward, so that there is a height difference between the sealing plate 24 and the rotating column 23. The friction pad 1 27 and the friction pad 28 come into contact, which is conducive to realizing the discharge operation.
[0097] As one embodiment of the present invention, the lower part of the discharge cylinder 5 also includes a stirring assembly. The stirring assembly includes a fixing plate 34, which is fixedly connected to the lower part of the discharge cylinder 5. The bottom of the fixing plate 34 is clamped to a stirring cylinder 35, and the bottom of the stirring cylinder 35 is fixedly connected to a second motor 36. The rotating shaft of the second motor 36 passes through the bottom surface of the stirring cylinder 35 and is fixedly connected to a stirring rod 37.
[0098] When the amount of solid tablets to be ground and pulverized is large during operation, in order to further improve the uniformity of mixing of the ground solid powder with water, the stirring drum 35 can be rotated and clamped onto the fixed plate 34. After the dissolved powder solution flows into the stirring drum 35 from the discharge port 501, the stirring rod 37 can be driven by the motor 36 to further stir it.
[0099] A method for controlling a grinding and dissolving apparatus for detecting solid pharmaceutical products includes the following steps:
[0100] Timer 39 receives the first information.
[0101] Timer 39 generates the first request information based on the first time information;
[0102] Timer 39 sends the first request information to controller 38.
[0103] After timer 39 sends the first request information to controller 38, the following steps are also included:
[0104] Controller 38 receives the first request information sent by timer 39;
[0105] Controller 38 generates first control information based on the first request information;
[0106] The controller 38 sends the first control information to the electromagnet 32.
[0107] After the controller 38 sends the first control information to the electromagnet 32, the following steps are also included;
[0108] Electromagnet 32 receives the first control information sent by controller 38;
[0109] Electromagnet 32 is activated.
[0110] The specific control process is as follows: Timer 39 acquires the first time information, generates the first request information based on the first time information, and sends the first request information to controller 38; Controller 38 acquires the first request information sent by Timer 39, generates the first control information based on the first request information, and sends the first control information to electromagnet 32; Electromagnet 32 acquires the first control information sent by controller 38 and starts.
[0111] The working principle of this invention is as follows: solid medicine is put into the tank 1 through the feed port at the top of the tank 1, and then the cap 3 is put on.
[0112] Before the grinding body 4 rotates, the solenoid valve 16 is opened, and the water pump 18 is started. The water pump 18 pumps the water in the water tank 17 into the inner cavity 10 through the pipe body 14 and the inlet pipe 12. The water in the inner cavity 10 flows back into the water tank 17 through the return pipe 13.
[0113] Start motor 7. Motor 7 drives gear 9 and grinding body 4 to rotate through gear 8, so that grinding body 4 can crush and grind solid drug particles. This is beneficial for cooling grinding body 4 during the drug grinding process.
[0114] After the medicine is ground and pulverized, the solenoid valve 16 is closed, and the water pump 18 continues to pump water into the inner cavity 10. After the water pressure in the inner cavity 10 exceeds the pressure preset value of the one-way valve in the spray head 20, the spray head 20 sprays water into the tank 1. This is beneficial for dissolving the ground and pulverized medicine particles and for promoting the stirring of the medicine powder by the grinding strip 21. On the other hand, it is beneficial for washing the medicine powder particles adsorbed on the inner wall of the tank 1 to the bottom of the tank 1. This helps to avoid the situation where the content of medicine powder dissolved in water is reduced due to the medicine powder adsorbed on the inner wall of the tank 1, resulting in a lower proportion of medicine powder dissolution and thus inaccurate test values.
[0115] After the drug granules are dissolved, during the discharge process, electromagnet 32 is activated. The opposite magnetic poles of electromagnet 32 and magnet block 31 are the same. Electromagnet 32 pushes magnet block 31 upward, and magnet block 31 pushes rotating column 23 upward, creating a height difference between sealing plate 24 and rotating column 23. The dissolved drug is discharged downward through discharge cylinder 5. At the same time, during the discharge process, friction pad 1 27 and friction pad 28 come into contact, which helps to drive rotating column 23 and propeller 25 to rotate through cylindrical rod 22. The rotation of propeller 25 is beneficial for both discharge and stirring of drug solution during the discharge process, which helps to further improve the uniformity of drug powder mixing in water.
[0116] Meanwhile, in order to further improve the uniformity of mixing of the ground solid powder with water, the stirring drum 35 can be rotated and clamped onto the fixed plate 34. After the dissolved powder solution flows into the stirring drum 35 from the discharge port 501, the stirring rod 37 can be driven by the motor 36 to further stir it.
[0117] The exterior of the tank 1 includes a heater 33, which is fixedly connected to the tank 1. After grinding and dissolving the solid medicine, the tank 1 can be cleaned by the water spray head 20. Then, the tank 1 can be heated and dried by the heater 33 to avoid residual moisture in the tank 1, which would affect the subsequent grinding and crushing of the solid medicine. It also helps to avoid contamination between different solid medicines.
[0118] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed invention.
