[0002] With rapid societal development, chronic diseases and mental health issues are becoming increasingly prominent, making medication management a crucial aspect of daily life. Current technologies suffer from scattered medication storage, and the ease with which medication times and dosages are forgotten, leading to poor medication adherence. For example, ordinary pillboxes cannot categorize and store multiple dosage forms (such as tablets, oral liquids, and sachets) and lack dispensing functionality, requiring users to manually sort medications, which is inefficient and prone to errors. To address this, many automated medication dispensing devices have emerged. For instance, Chinese utility model patent CN215873954U discloses a home-use intelligent medicine cabinet capable of dispensing quantitatively. This cabinet includes a main body, drawers, a single-powder dispensing mechanism, and a conveyor belt. The single-powder dispensing mechanism dispenses packets of pills, which are then conveyed out via the conveyor belt, enabling automated dispensing of multiple medications. However, the matrix-arranged drawers for storage and the layered conveyor belt transport method consumes a significant amount of space, making it inconvenient for home placement. Furthermore, medications still need to be retrieved one by one from each layer, resulting in poor usability. Utility Model Content

Detailed Implementation

[0024] The present invention will be further described below with reference to the accompanying drawings and embodiments, but this should not be construed as limiting the present invention.

[0025] Example: A multi-dosage form drug dispensing device, as shown in the attached document. Figure 1 As shown, it includes a bottom compartment 1 with an open top, a middle compartment 2 with an open top fixed inside the bottom compartment 1, and a top compartment 3 threadedly fitted to the top of the middle compartment 2; as shown in the attached diagram. Figure 2 -Appendix Figure 4 As shown, the intermediate compartment 2 is equipped with a bottled tablet dispensing mechanism 4, and the side of the intermediate compartment 2 is integrally formed with an intermediate dispensing channel 5 corresponding to the dispensing end of the bottled tablet dispensing mechanism 4; the inner cavity of the bottom compartment 1 and the outer wall of the intermediate compartment 2 enclose an oral liquid and bagged medicine cavity 6; the top compartment 3 has a slab-type drug dispensing mechanism 7, and the side of the top compartment 3 is provided with an upper dispensing channel 8 corresponding to the dispensing end of the slab-type drug dispensing mechanism 7, which is connected to the intermediate dispensing channel 5; the side of the bottom compartment 1 has a dispensing port 9 that communicates with the lower end of the intermediate dispensing channel 5; as shown in the attached figure. Figure 5As shown, the slab-filled drug dispensing mechanism 7 includes a slab insert 10 located on the side of the top chamber 3. A slab guide rail 11 corresponding to the slab insert 10 is fixed inside the top chamber 3. A mounting plate 12 is fixed above the slab guide rail 11, and an arc-shaped first guide plate 13 with its end corresponding to the inlet of the upper drug dispensing channel 8 is fixed below the slab guide rail 11. The bottom surface of the mounting plate 12 is equipped with a slab drive wheel 14 driven by a motor and a transverse drive screw 15. A parallel guide rod 16 is mounted above the transverse drive screw 15. A moving block 17 cooperating with the drive screw 15 is mounted on the guide rod 16. A motor-driven guide rod 17 is mounted on the moving block 17 and faces the first guide plate 13. The ejector pin 18 has a camera assembly mounted on its mounting plate for visual inspection of the medicine plate. The transverse drive screw 15 is perpendicular to the setting direction of the medicine plate guide rail 11. The driving direction of the medicine plate drive wheel 14 is parallel to the medicine plate guide rail 11. When the medicine plate is inserted into the medicine plate slot with the back side facing upward, the medicine plate drive wheel is in contact with the medicine plate. When rotating, it drives the pressure plate to move directionally on the medicine plate guide rail. The drive screw drives the moving block to move perpendicularly to the medicine plate guide rail on the guide rod. When the ejector pin reaches the position of the medicine pellet, it moves downward and pushes the medicine pellet out of the medicine plate so that it falls into the first guide plate. The first guide plate guides the medicine pellet into the upper medicine outlet channel. The number of times the ejector pin pushes is the number of medicine pellets, realizing quantitative medicine dispensing; as shown in the attached figure. Figure 6 and attached Figure 7As shown, the bottled tablet dispensing mechanism 4 includes a base plate 19 fixed inside the intermediate compartment 2. A bottom shell 20 is magnetically connected to the top surface of the base plate 19. A dispensing port 21 communicating with the bottom shell 20 is opened on the base plate 19. A curved pipe 22 connecting the dispensing port 21 and the inlet of the intermediate dispensing channel 5 is fixed to the bottom surface of the base plate 19. An infrared sensor for detecting the passage of tablets is installed inside the curved pipe. A storage shell 23 is fixed to the top of the bottom shell 20, and the top of the storage shell 23 is threaded together... The bottom shell 20 is equipped with a medicine storage cover 24; a rotating disk 25 driven by a motor is installed inside the bottom shell 20, and the rotating disk 25 has a medicine dispensing hole 26 corresponding to the medicine dispensing port 21; a fan-shaped medicine pushing plate 27 coaxially connected to the rotating disk 25 is installed inside the medicine storage shell 23, and a single medicine tablet storage port 28 is opened on the bottom surface of the medicine storage shell 23; the fan-shaped medicine pushing plate 27 and the rotating disk 25 are respectively attached to the upper and lower surfaces of the bottom surface of the medicine storage shell 23; a drive gear 29 driven by a motor is provided on the bottom plate. The outer edge of the rotating disk 25 is provided with driving teeth 30 that are adapted to the driving gear 29. After removing the top chamber, pull out the bottom shell and the medicine storage shell, open the medicine storage cap, put in the bottled tablets, and put the bottom shell back in so that the driving gear meshes with the driving teeth of the rotating disk. In use, the rotating disk is driven to rotate by the driving gear. When rotating, it drives the fan-shaped medicine pushing plate to rotate. The fan-shaped medicine pushing plate pushes one of the tablets in the medicine storage shell into the single tablet storage port. When the medicine dropping hole of the rotating disk reaches the position of the single tablet storage port, the tablet enters the curved tube through the medicine dropping hole and is guided to the middle medicine dispensing channel. This is repeated to achieve the dispensing of a specified number of tablets. There are multiple intermediate chambers 2, which are arranged and connected in sequence from bottom to top. The top chamber 3 is connected to the top intermediate chamber 2, and can be arbitrarily combined to dispense various bottled tablets. The oral liquid and bagged medicine cavity 6 is fixed with a partition plate 31. The two sides of the partition plate 31 form a first partition cavity 32 and a second partition cavity 33, respectively. As shown in the attached figure Figure 8As shown, a second guide plate 34 is fixed inside the first partition cavity 32. The second guide plate 34 and the outer wall of the intermediate compartment 2 enclose a bottled medicine guiding passage 35. A transverse spring 36 is fixed at the inner end of the guiding passage 35. A cross pusher block 37 driven by a servo motor is installed on one side of the outer end of the guiding passage 35. The gap of the cross pusher block engages with the outer bottle of the bottled medicine. When rotated, it is pulled out. The amount of medicine dispensed can be controlled by controlling the rotation angle, which improves the convenience of use. A baffle 38 is fixed in the second partition cavity 33. The baffle 38 and the outer wall of the intermediate compartment 2 enclose a bagged medicine stacking chamber 39. A bagged medicine outlet 40 is opened at the bottom of the baffle 38. A pusher gear 41 driven by a servo motor is provided on one side of the bagged medicine outlet 40. The bagged medicine is stacked in the bagged medicine stacking chamber. The servo motor drives the pusher gear to push the bagged medicine out of the stacking chamber. The bottom-layer bagged medicine is pushed out, and the quantitative dispensing can be achieved by controlling the rotation angle, improving the convenience of use. It also includes a controller and drive power supply set in the cavity at the bottom of the bottom compartment. After connecting to each drive component and detection component, it is used to send and receive signals. The top compartment and the middle compartment are respectively fixed with a magnetic information transmitter male head 42 (such as a 14-pin magnetic interface) and a magnetic information transmitter female head 43. The two are electrically connected to the drive component and controller of the plate-type medicine dispensing mechanism, respectively. After the threads of the top compartment and the middle compartment are screwed together, the magnetic information transmitter male head and the magnetic information transmitter female head approach and attract each other to realize electrical and information transmission. The controller realizes quick timing and quantitative control through signal reception and output. Its circuit connection method is a technical means that is well known and mastered by those skilled in the art, and will not be described in detail here.

[0026] Working principle: Before use, the medicine needs to be loaded: remove the top compartment 3, put bottled tablets into the middle compartment 2, open the medicine storage cover 24, pour the tablets into the medicine storage shell 23, and then reset the medicine storage cover 24 and the bottom shell 20 through the threaded quick release structure, so that the drive gear 29 and the drive gear 30 of the rotating disk 25 can be precisely meshed; in the top compartment 3, insert the plate medicine from the medicine plate insertion port 10, the medicine plate is positioned along the medicine plate guide rail 11, and the back side is in contact with the medicine plate drive wheel 14; the first partition cavity 32 and the second partition cavity 33 are used to store bottled oral liquid and stacked bagged medicine respectively, to complete the classification and storage of multi-dosage form medicines.

[0027] Plate-loaded drug dispensing: The drive wheel 14 of the drug plate rotates, causing the drug plate to move laterally along the guide rail 11. At the same time, the drive screw 15 drives the moving block 17 to move vertically along the guide rod 16, so that the ejector pin 18 is aligned with the drug granule position on the drug plate. The ejector pin motor drives the ejector pin 18 to push the drug granule downward. The drug granule slides down through the first guide plate 13 to the upper drug dispensing channel 8. The number of pushes of the ejector pin corresponds to the number of drugs dispensed, realizing quantitative control.

[0028] Dispensing bottled tablets: Drive gear 29 rotates under the drive of motor, meshing with drive teeth 30 on the edge of rotating disk 25, so that rotating disk 25 and sector-shaped pusher plate 27 rotate coaxially. The sector-shaped pusher plate 27 pushes the tablets in the storage shell 23 one by one into the single tablet storage port 28. When the drop hole 26 of rotating disk 25 is aligned with the storage port, the tablets fall into the bent tube 22 through the drop port 21.

[0029] Oral liquid and bagged medicine removal: In the first partition chamber 32, bottled medicine is stored along the guide passage 35. The inner end spring 36 holds the bottle body, and the servo motor drives the cross push block 37 to rotate, which pushes the bottle body outward through the gap. The rotation angle determines the amount of medicine dispensed. In the second partition chamber 33, bagged medicine is stacked between the baffle 38 and the outer wall of the intermediate compartment. The push gear 41 rotates under the drive of the servo motor, pushing the bottom bagged medicine out of the medicine outlet 40.

[0030] Various medications are delivered through the upper medication outlet 8 and the middle medication outlet 5, and finally sent out from the medication outlet 9 on the side of the bottom compartment 1. All medications can be retrieved from the bottom compartment. The vertical layout and shared channel design reduce horizontal space occupation and improve ease of use.
