Description

Technical Field

[0001] This utility model relates to the field of drug dissolution testing, and in particular to a dosing device for a drug dissolution apparatus. Background Technology

[0002] A drug dissolution apparatus, also known as a drug dissolution tester, is an experimental device used to determine the dissolution rate and dissolution behavior of drugs under specific conditions. By simulating the environmental conditions inside the human digestive tract, the drug dissolution apparatus analyzes the release of drugs from drug formulations within a certain period of time. It uses in vitro simulation technology to set specific experimental conditions (such as temperature, stirring speed, etc.) and places the drug formulation in an appropriate solution medium for dissolution and release, thereby evaluating the drug release performance.

[0003] Using a drug dissolution apparatus to test the dissolution rate of drugs is an important part of pharmaceutical experiments. Drug delivery is an important step in the operation of a drug dissolution apparatus. In existing drug dissolution apparatuses, the drug delivery process involves controlling the movement time of the delivery strip and the movement distance of the delivery strip by controlling the delivery time of the delivery strip by the delivery motor.

[0004] According to the Chinese Patent Publication No. CN219871277U, a dosing device for a drug dissolution apparatus includes a frame and a dosing chamber. The frame has multiple equally spaced openings, and the dosing chamber is fixedly installed at each opening. The device also includes a sealing plate, symmetrically and slidably connected to the lower end of the frame at the opening, and slidably attached to the outlet of the dosing chamber. This invention allows for the delivery of small amounts of drug into the dosing tube multiple times, preventing blockage and effectively improving the stability of drug dosing into the dissolution vessel. Compared to existing technologies that rely on shaking the drug up and down to ensure uniform drug distribution, this invention not only avoids blockage of the dosing tube, thus preventing the stability of the dosing operation, but also prevents damage to the drug during shaking, which could affect the accuracy of drug dissolution rate detection, effectively ensuring the integrity of the drug.

[0005] However, since the dosage of the drug needs to be added according to the detection amount, the above device cannot quantitatively add the drug, resulting in too much or too little drug being added during the experiment, which affects the detection effect. Utility Model Content

[0006] The purpose of this invention is to provide a dosing device for a drug dissolution apparatus. This device has the advantage of facilitating the quantitative determination of the amount of drug added by controlling the height of the dispensing plate in the dispensing tube, thereby improving the detection effect.

[0007] The purpose of this invention is to provide a dosing device for a drug dissolution apparatus, comprising a base plate, a main board fixedly connected to one end of the base plate, multiple dosing tubes for convenient drug placement fixedly connected to the surface of the main board, multiple stirring mechanisms for stirring the drugs installed inside the multiple dosing tubes, a blocking plate slidably connected below the multiple dosing tubes, multiple discharging tubes for convenient drug discharge fixedly connected to one end of the blocking plate, multiple inclined discharging plates slidably connected to the inner wall of the multiple discharging tubes, a lifting mechanism for driving the discharging plates to rise and fall at one end of each discharging plate, and a transmission mechanism for driving the blocking plates to move on the surface of the main board.

[0008] Furthermore, multiple dosing tubes correspond to multiple dispensing tubes, and the dispensing tubes and dosing tubes are interconnected.

[0009] Furthermore, the stirring mechanism includes a motor fixedly connected to one end of the dosing pipe, and a stirring rod for stirring the medicine is fixedly connected to the output shaft of the motor. Rubber rods for stirring the medicine are fixedly connected to the surface of the stirring rod.

[0010] Furthermore, a filter plate is fixedly connected to the other end of the dosing tube to facilitate the slow discharge of the medicine.

[0011] Furthermore, the lifting mechanism includes a fixed block fixedly connected to one end of the blocking plate, a second motor fixedly connected to one end of the fixed block, a lead screw fixedly connected to the output shaft of the second motor, and a lifting rod slidably connected to one side of the fixed block by a threaded connection on the surface of the lead screw. One end of the lifting rod is fixed to the medicine dispensing plate, thereby driving the medicine dispensing plate to rise and fall.

[0012] Furthermore, the transmission mechanism includes two electric telescopic rods fixedly connected to the surface of the main board. The output shafts of the two electric telescopic rods are fixedly connected to a transmission plate that is slidably connected to the surface of the main board. One end of the transmission plate is fixedly connected to the surface of the blocking plate, driving the blocking plate to slide at one end of multiple dosing tubes.

[0013] The working principle and usage principle of this utility model are as follows: The device is fixedly connected to the surface of the drug dissolution apparatus. The drug is placed in multiple dosing tubes. Motor 1 drives the stirring rod to rotate, which in turn drives the rubber rod to rotate. The rubber rod can prevent damage to the drug, allowing the drug to be slowly discharged through the filter plate and fall into the dispensing tube. Motor 2 drives the lead screw to rotate, which in turn drives the lifting rod to move up and down. At the same time, the lifting rod drives the dispensing plate to slide on the inner wall of the dispensing tube. By controlling the height of the dispensing plate in the dispensing tube, the amount of drug falling into the dispensing tube is changed, thereby quantifying the amount of drug added. Then, two electric telescopic rods are activated, which drive the transmission plate to slide on the main plate surface. At the same time, the transmission plate drives the blocking plate to slide below the dosing tube, causing the blocking plate to pull the dispensing tube away from the dosing tube. At the same time, the other end of the blocking plate blocks the dosing tube. Then, the lifting rod drives the dispensing plate to detach from the dispensing tube. The drug is introduced into the drug dissolution apparatus through the tilted dispensing plate. By controlling the height of the dispensing plate in the dispensing tube, it is convenient to quantify the amount of drug added, thus improving the detection effect.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: The device is fixedly connected to the surface of the drug dissolution apparatus. The drug is placed in multiple dosing tubes. The stirring mechanism stirs the drug in the dosing tubes, causing the drug to slowly fall into the dispensing tube. The lifting mechanism drives the dispensing plate to rise and fall. By controlling the height of the dispensing plate, the drug is quantified. When the drug is in the dispensing tube, it is placed on the surface of the inclined dispensing plate. The transmission mechanism is activated to drive the blocking plate to slide below the dosing tube. At the same time, the stirring mechanism is stopped, causing the blocking plate to drive the dispensing tube to detach from the dosing tube. Simultaneously, the other end of the blocking plate blocks the dosing tube. Then, the lifting mechanism drives the dispensing plate to rise and fall. When the dispensing plate detaches from the dispensing tube, the drug is introduced into the drug dissolution apparatus through the inclined dispensing plate. By controlling the height of the dispensing plate in the dispensing tube, it is convenient to quantify the amount of drug added, thus improving the detection effect.

[0015] 1. Compared with the prior art, this utility model has the advantage of facilitating the quantitative determination of the amount of medicine added by controlling the height of the dispensing plate in the dispensing tube, thereby improving the detection effect.

[0016] 2. Compared with the prior art, this utility model has the advantages of preventing drug adhesion and improving the quality of testing. Attached Figure Description

[0022] To make the technical means, creative features, objectives and effects of the embodiments of this application easier to understand, the embodiments of this application are further described below in conjunction with the figures and specific embodiments. It should be understood that the specific embodiments described herein are only used to explain the embodiments of this application and are not intended to limit the embodiments of this application.

[0023] The dosing device for the drug dissolution apparatus in this specific embodiment, such as Figure 1-4 As shown, the dosing device for a drug dissolution apparatus includes a base plate 1. A main plate 2 is fixedly connected to one end of the surface of the base plate 1. Multiple dosing tubes 3 are fixedly connected to the surface of the main plate 2 for convenient placement of drugs. Multiple stirring mechanisms are installed inside the multiple dosing tubes 3 to stir the drugs in the dosing tubes 3, causing the drugs to slowly fall into the dispensing tubes 5. A blocking plate 4 is slidably connected below the multiple dosing tubes 3. Multiple dispensing tubes 5 are fixedly connected to one end of the blocking plate 4 for convenient discharge of drugs. The inner walls of the multiple dispensing tubes 5 are slidably connected to tilting mechanisms. Multiple dispensing plates 6 are set at an angle. When the medicine is in the dispensing tube 5, the medicine is placed on the surface of the inclined dispensing plate 6 for easy subsequent dosing. Each of the multiple dispensing plates 6 is equipped with a lifting mechanism that drives the dispensing plate 6 to rise and fall. The height of the dispensing plate 6 is controlled to quantify and dispense the medicine. The main board 2 is equipped with a transmission mechanism that drives the blocking plate 4 to move. The transmission mechanism drives the blocking plate 4 to slide below the dosing tube 3. Multiple dosing tubes 3 correspond to multiple dispensing tubes 5, and the dispensing tubes 5 and dosing tubes 3 are interconnected.

[0024] The above technical solution involves fixing the device to the surface of a drug dissolution apparatus. Drugs are placed in multiple dosing tubes 3, and a stirring mechanism agitates the drugs within the dosing tubes 3, causing them to slowly fall into the dispensing tube 5. A lifting mechanism moves the dispensing plate 6 up and down, controlling the height of the dispensing plate 6 to quantify the drug dosage. When the drug is in the dispensing tube 5, it rests on the inclined surface of the dispensing plate 6. A transmission mechanism is activated, causing a blocking plate 4 to slide below the dosing tube 3. Simultaneously, the stirring mechanism stops, causing the blocking plate 4 to disengage the dispensing tube 5 from the dosing tube 3. At the same time, the other end of the blocking plate 4 blocks the dosing tube 3. Then, the lifting mechanism moves the dispensing plate 6 up and down. When the dispensing plate 6 disengages from the dispensing tube 5, the drug is introduced into the drug dissolution apparatus through the inclined dispensing plate 6. By controlling the height of the dispensing plate 6 within the dispensing tube 5, the amount of drug added can be quantified, improving the detection effect.

[0025] like Figure 1-4 As shown, the stirring mechanism includes a motor 7 fixedly connected to one end of the dosing tube 3. The output shaft of the motor 7 is fixedly connected to a stirring rod 8 for stirring the medicine. Rubber rods 9 for stirring the medicine are fixedly connected to the surface of the stirring rod 8. A filter plate 10 for facilitating the slow discharge of the medicine is fixedly connected to the other end of the dosing tube 3.

[0026] Through the above technical solution, motor 7 drives stirring rod 8 to rotate, which in turn drives rubber rod 9 to rotate. Rubber rod 9 can prevent damage to the medicine and allow the medicine to be slowly discharged through filter plate 10. At the same time, during the stirring process, it prevents the medicine from sticking together.

[0027] like Figure 1-4 As shown, the lifting mechanism includes a fixed block 11 fixedly connected to one end of the blocking plate 4. A motor 12 is fixedly connected to one end of the fixed block 11. A lead screw 13 is fixedly connected to the output shaft of the motor 12. A lifting rod 14 is threadedly connected to one side of the fixed block 11. One end of the lifting rod 14 is fixed to the dispensing plate 6, driving the dispensing plate 6 to rise and fall. The transmission mechanism includes two electric telescopic rods 15 fixedly connected to the surface of the main board 2. The output shafts of the two electric telescopic rods 15 are fixedly connected to a transmission plate 16 slidably connected to the surface of the main board 2. One end of the transmission plate 16 is fixedly connected to the surface of the blocking plate 4, driving the blocking plate 4 to slide at one end of the multiple dosing tubes 3.

[0028] Through the above technical solution, motor 12 drives screw 13 to rotate, causing screw 13 to drive lifting rod 14 to move up and down. At the same time, lifting rod 14 drives dispensing plate 6 to slide on the inner wall of dispensing tube 5. By controlling the height of dispensing plate 6 in dispensing tube 5, the amount of drug falling into dispensing tube 5 is changed, thereby quantifying the amount of drug added. Then, two electric telescopic rods 15 are activated, causing transmission plate 16 to slide on the surface of main plate 2. At the same time, transmission plate 16 drives blocking plate 4 to slide below dispensing tube 3, causing blocking plate 4 to drive dispensing tube 5 away from dispensing tube 3. At the same time, the other end of blocking plate 4 blocks dispensing tube 3. Then, lifting rod 14 drives dispensing plate 6 away from dispensing tube 5, and the drug is introduced into drug dissolution apparatus through the tilted dispensing plate 6.

[0029] Motor 2 12, Motor 1 7 and Electric Telescopic Rod 15 are controlled by a controller fixedly connected to the surface of the main board 2. This is existing technology and will not be described in detail.

[0030] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
