The various technical features of the embodiments described above may be combined arbitrarily. To simplify the description, not all possible combinations of the various technical features in the embodiments described above are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0039] like Figure 1 As shown, a schematic diagram of the drug delivery structure.

[0040] A drug delivery structure 200 includes a fixing post (not shown), a plurality of first connecting members 10 and a plurality of second connecting members 20;

[0041] The first connecting member 10 is generally L-shaped, and the two long sides of the short bottom surface of the first connecting member 10 are respectively provided with first connecting columns 103;

[0042] The second connecting member 20 is generally L-shaped, and the two long sides of the short bottom surface of the second connecting member 20 are respectively provided with second connecting posts corresponding to the first connecting posts 103;

[0043] After a plurality of the first connecting posts 103 and a plurality of the second connecting posts are buckled in pairs, they are fixedly connected by the fixing posts (not shown) to form the drug delivery structure 200 .

[0044] Please combine Figure 2 The first connector 10 includes a first long bottom surface 101, a first short bottom surface 102, and a first connecting post 103. The first long bottom surface 101 and the first short bottom surface 102 are generally perpendicular to each other. The first connecting post 103 is disposed on the edge formed by the intersection of the first long bottom surface 101 and the first short bottom surface 102. The first connecting post 103 is also disposed parallel to the other edge of the first short bottom surface 102. That is, two parallel first connecting posts 103 are disposed on two opposite long sides of the first short bottom surface 102.

[0045] Please combine Figure 3 The second connecting member 20 includes a second long bottom surface 201, a second short bottom surface 202, and a second connecting post. The second long bottom surface 201 and the second short bottom surface 202 are generally perpendicular to each other. The second connecting post is located on the edge where the second long bottom surface 201 and the second short bottom surface 202 intersect, and a second connecting post is located parallel to the other edge of the second short bottom surface 202. In other words, two parallel second connecting posts are located on two opposing long sides of the second short bottom surface 202.

[0046] The first long bottom surface 101 of the first connector 10 is fitted and connected to the second long bottom surface 201 of the second connector 20, and the first short bottom surface 102 of the first connector 10 is in contact with the second short bottom surface 202 of the second connector 20. Therefore, the first connecting column 103 at the edge of the first long bottom surface 101 can be fastened to the second connecting column at the edge of the second long bottom surface 201, and the first connecting column 103 at the edge of the first short bottom surface 102 can be fastened to the second connecting column at the edge of the second short bottom surface 202. The first connecting column 103 and the second connecting column are then fixed by a fixing column (not shown), thereby achieving a fixed connection between the first connector 10 and the second connector 20. After several first connectors 10 and second connectors 20 are fastened together, a drug delivery structure 200 can be formed.

[0047] The first connecting post 103 includes a first circular connecting post 1031 and a first semicircular connecting post 1032. The first circular connecting post 1031 is disposed at the edges of the two long sides of the first short bottom surface 102, and the first semicircular connecting post 1032 is disposed in the middle of the two long sides of the first short bottom surface 102.

[0048] The second connecting column includes a second circular connecting column 2031 and a second semicircular connecting column 2032. The second circular connecting column 2031 and the second semicircular connecting column 2032 are set at positions corresponding to the positions of the first circular connecting column 1031 and the first semicircular connecting column 1032, that is, the first connecting column 103 can be exactly engaged with the second connecting column.

[0049] The first circular connecting column 1031, the first semicircular connecting column 1032, the second circular connecting column 2031, and the second semicircular connecting column 2032 are all hollow, which enables the fixing column (not marked) to pass through the first circular connecting column 1031, the first semicircular connecting column 1032, the second circular connecting column 2031, and the second semicircular connecting column 2032, thereby achieving the fixation of the first connecting member 10 and the second connecting member 20.

[0050] The length of the drug delivery structure 200 can be set according to the actual needs of the user. Therefore, the number of the first connecting member 10 and the second connecting member 20 can be freely set according to the actual needs of the user.

[0051] In this embodiment, the radial cross-section of the drug delivery structure 200 is substantially elliptical. Therefore, at the two top ends of the ellipse, the first connecting member 10 and the second connecting member 20 will be opened due to the tension.

[0052] A U-shaped cutout is provided on one edge of the first long bottom surface 101 away from the first short bottom surface 102. A U-shaped cutout is provided on one edge of the second long bottom surface 201 away from the second short bottom surface 202, which is identical to the U-shaped cutout of the first long bottom surface 101.

[0053] When drug delivery structure 200 is required to transport smaller-volume medications (e.g., ampoules), washers can be placed along all U-shaped cutouts to reduce the space between the first connector 10 and the second connector 20. When transporting larger-volume medications (e.g., vials), washers are eliminated. This arrangement allows drug delivery structure 200 to accommodate medications of various sizes and, when transporting smaller-volume medications, prevents the misplacement of multiple medications due to excessive space.

[0054] Please combine Figure 4 In this embodiment, the drug delivery structure 200 further includes a third connecting member 30, and the two long sides of the third connecting member 30 are respectively provided with the first connecting column 103 and the second connecting column. The first connecting column 103 of the third connecting member 30 is buckled with the second connecting column of the second connecting member 20 and then fixedly connected via the fixing column (not marked), and the second connecting column of the third connecting member 30 is buckled with the first connecting column 103 of the first connecting member 10 and then fixedly connected via the fixing column (not marked).

[0055] The third connector 30 is sheet-shaped and includes a third long bottom surface 301 and first and second connecting posts 103 and 20 disposed on opposite long sides of the third long bottom surface 301. The third connector 30 is provided to widen the receiving space formed by the first and second connectors 10 and 20, facilitating the management of larger volumes of medication.

[0056] In this embodiment, the first connecting column 103 includes a first circular connecting column 1031 and a first semicircular connecting column 1032 that are intermittently arranged, and the first circular connecting column 1031 and the first semicircular connecting column 1032 are on the same axis; the second connecting column includes a second circular connecting column 2031 and a second semicircular connecting column 2032 that are intermittently arranged, and the second circular connecting column 2031 and the second semicircular connecting column 2032 are on the same axis.

[0057] In other embodiments, the first connecting post 103 may include only one first circular connecting post 1031, and the second connecting post may include only one second circular connecting post 2031. That is, the first connecting post 103 and the second connecting post can be fixed by fixing posts (not shown).

[0058] Based on all the above embodiments, the radial diameters of the first circular connecting post 1031, the first semicircular connecting post 1032, the second circular connecting post 2031, and the second semicircular connecting post 2032 are equal. The widths of the first short bottom surface 102, the second short bottom surface 202, and the third long bottom surface 301 are equal.

[0059] Please combine Figure 1 In this embodiment, the drug delivery structure 200 further includes a light shielding sheet 204 , which is vertically disposed on the short bottom surface of the first connecting member 10 or the short bottom surface of the second connecting member 20 .

[0060] Please combine Figure 2 In this embodiment, the light shielding sheet 204 is disposed on the second short bottom surface 202 of the second connecting member 20 and is perpendicular to the second short bottom surface 202 of the second connecting member 20. The light shielding sheet 204 is used to block the light emitted by the laser counter, and each blockage is counted once.

[0061] The drug delivery structure 200 is formed by fastening the first and second connectors 10, 20 in pairs, and then securing them with a fixing post (not shown). Thus, the short bottom surfaces of the first and second connectors 10, 20 are connected to their long bottom surfaces to form a receiving space for the drug. Each container formed by two adjacent first and second connectors 10, 20 can only hold one drug. Rotation of the drug delivery structure 200 drives the drug within the receiving space, thereby achieving drug delivery.

[0062] If the medicine is large, a third connector 30 is added to expand the storage space. That is, the first connector 10, the second connector 20, and the third connector 30 together form a storage space for the medicine. The thickness and width of the bottom surfaces of the first connector 10, the second connector 20, and the third connector 30 can be adjusted according to the size of the medicine to be transported.

[0063] If the medicine is small in size, only the first connector 10 and the second connector 20 are used to form a storage space for the medicine. If the storage space formed can accommodate two medicines at the same time, a gasket needs to be installed at the opening of the first connector 10 and the second connector 20 to reduce the storage space and prevent the user from placing two medicines in the same storage space at the same time.

[0064] like Figure 5 Shown is a module diagram of a drug delivery device.

[0065] A drug delivery device, comprising the drug delivery structure 200, a source drive module 502 for providing a driving force, a main drive module 503, and a housing 501;

[0066] The driving force of the source driving module 502 is transmitted to the main driving module 503; the main driving module 503 is used to drive the drug delivery structure 200 to rotate around the main driving module 503; when the drug delivery structure 200 rotates, it drives the drug placed in the drug delivery structure 200 to move; the shell 501 is used to accommodate the source driving module 502, the main driving module 503 and the drug delivery structure 200; the shell 501 is also provided with a drug outlet.

[0067] In this embodiment, the source driving module 502 includes a motor 5021 and a first rotating wheel 5022 . The motor 5021 is fixedly connected to the first rotating wheel 5022 . When the motor 5021 rotates, the first rotating wheel 5022 is driven to rotate.

[0068] The rotating shaft of the motor 5021 is fixedly connected to the axis of the first rotating wheel 5022. When the motor 5021 rotates, it drives the first rotating wheel 5022 to rotate. Therefore, the first rotating wheel 5022 drives the other rotating wheels connected thereto to rotate through gear transmission.

[0069] The main driving module 503 includes a third rotating wheel 5032, a first rotating shaft 5033 and a first sprocket 5031;

[0070] Please combine Figure 6The first rotating shaft 5033 is disposed in the first sprocket 5031. One free end of the first rotating shaft 5033 is fixedly connected to the axis of the third rotating wheel 5032, and the other free end is received in the housing 501. When the third rotating wheel 5032 rotates, it drives the first rotating shaft 5033 to rotate, thereby driving the first sprocket 5031 to rotate.

[0071] Without the transmission module 505, the first rotating wheel 5022 is directly gear-engaged with the third rotating wheel 5032. Rotation of the first rotating wheel 5022 drives the third rotating wheel 5032 to rotate. The axis of the third rotating wheel 5032 is fixedly connected to the first rotating shaft 5033. Simultaneously, the first rotating shaft 5033 is fixedly connected to the first sprocket 5031. Therefore, rotation of the third rotating wheel 5032 drives both the first rotating shaft 5033 and the first sprocket 5031 to rotate simultaneously.

[0072] The tooth grooves and tooth arrangement of the first sprocket 5031 match the first connecting post 103, first short bottom surface 102, second connecting post, and second short bottom surface 202 in the drug delivery structure 200. That is, the first connecting post 103 and the second connecting post fall into the grooves of the first sprocket 5031, and the teeth of the first sprocket 5031 fall into the first short bottom surface 102 and the second short bottom surface 202. If the third connecting member 30 is added to the drug delivery structure 200, the teeth of the first sprocket 5031 will fall into the first short bottom surface 102, the second short bottom surface 202, and the third long bottom surface 301, respectively.

[0073] In this embodiment, the first rotating shaft 5033 is cut along the radial direction, so that no relative displacement occurs between the first rotating shaft 5033 and the first sprocket 5031 .

[0074] Please combine Figure 6 In this embodiment, the drug delivery device further comprises a transmission module 505 connected to the source driving module 502 and the active driving module respectively;

[0075] The transmission module 505 is used to transmit the driving force of the source driving module 502 to the main driving module 503 .

[0076] The transmission module 505 includes a second rotating wheel 505 , and the second rotating wheel 505 is connected to the source driving module 502 . When the source driving module 502 rotates, the second rotating wheel 505 is driven to rotate.

[0077] Please combine Figure 7 The drug delivery device further includes a slave driving module 506 , which is disposed opposite to the main driving module 503 , so that the delivery module rotates around the main driving module 503 and the slave driving module 506 at the same time.

[0078] The slave driving module 506 includes a second rotating shaft 5063 and a second sprocket 5061;

[0079] The second rotating shaft 5063 passes through the second sprocket 5061 , and a free end of the second rotating shaft 5063 is received in the housing 501 . When the first sprocket 5031 rotates, the first rotating shaft 5033 is driven to rotate.

[0080] In this embodiment, the slave drive module 506 further includes a sleeve 5062, a spring member 5064, and a fixing member 5065. The sleeve 5062 is respectively mounted on the two free ends of the second rotating shaft 5063, and the radially extending free end of the sleeve 5062 is connected to the fixing member 5065. The spring member 5064 is mounted on the free end of the sleeve 5062. When radial tension is generated during the rotation of the slave drive module 506, the sleeve 5062 and the spring member 5064 deform to offset the tension. When radial pressure is generated during the rotation of the slave drive module 506, the sleeve 5062 and the spring member 5064 deform to offset the tension. Thus, the drug delivery structure 200 can rotate tightly around the main drive module 503 and the slave drive module 506.

[0081] Please combine Figure 8 .

[0082] The source drive module 502, transmission module 505, and main drive module 503 are sequentially arranged within the hollow space formed by the drug delivery structure 200, wherein the first sprocket 5031 of the main drive module 503 is in contact with the drug delivery structure 200. Because the arrangement of the first connecting tooth grooves and gear teeth completely matches the first connecting column 103, second connecting column, first short bottom surface 102, and second short bottom surface 202 of the drug delivery structure 200, when the main drive module 503 rotates, it can drive the drug delivery structure 200 to rotate around the main drive module 503.

[0083] To ensure more stable rotation of the drug delivery structure 200, a slave drive module 506 is provided at the other end of the drug delivery structure 200. The second sprocket 5061 of the slave drive module 506 is structurally identical to the first sprocket 5031. Therefore, the second sprocket 5061 can also drive the drug delivery structure 200 to rotate around the main drive module 503.

[0084] Please combine Figure 8 and Figure 9 The housing 501 includes a receiving slot and a top cover; the receiving slot is used to receive the source drive module 502, the main drive module 503 and the drug delivery structure 200, and the receiving slot is also provided with the drug outlet; one side of the receiving slot opening is movably connected to the top cover.

[0085] The drug delivery device also includes a first bottom cover (not shown) and a second bottom cover (not shown), which respectively cover the two side surfaces formed when the drug delivery structure 200 rotates around the main drive module 503.

[0086] Based on all of the above embodiments, the source drive module 502 provides driving force, driving the transmission module 505, which then transmits the driving force to the main drive module 503. Consequently, the main drive module 503 can drive the drug delivery structure 200 to rotate about the main drive module 503. Simultaneously, the slave drive module 506 is provided, enabling the drug delivery structure 200 to more stably rotate about the main and slave drive modules 503, 506. After the housing 501 houses the drug delivery structure 200, the source drive module 502, the transmission module 505, the main drive module 503, and the slave drive module 506, medication is placed within the storage compartments of the drug delivery structure 200. Each storage compartment can only hold one medication. Therefore, as the drug delivery structure 200 rotates, it also drives the medication along. When medication is needed, the drug delivery structure 200 is controlled to move to a specific position, allowing the medication to flow into the opening of the housing 501, where it automatically drops out, achieving single-dose medication removal.

[0087] In other embodiments, the transmission module and / or the slave drive module 506 may not be used, and the function of controlling a single drug can also be achieved.

[0088] The above-described drug delivery device can manage and control individual medications. Each receiving space in the drug delivery structure 200 houses a medication, and the size of the receiving space can be adjusted based on the volume of the medication, allowing it to precisely accommodate a single medication. Compared to traditional single-drug management structures, the above-described drug delivery device has a simpler structure and can adjust the receiving space based on the volume of the medication being managed. This allows for compatibility with medications of various specifications by simply adding or removing gaskets without changing the main structure.

[0089] The drug delivery device utilizes a source drive module 502 to provide driving force, causing the main drive module 503 to rotate. This in turn drives the drug delivery structure 200, causing the drug contained within the drug delivery structure 200 to follow the movement of the drug delivery structure 200. The housing 501 houses the source drive module 502, the main drive module 503, and the drug delivery structure 200, preventing drug from scattering during delivery and thus achieving drug delivery. Compared to conventional drug delivery devices, this device utilizes fewer components, thereby reducing product costs.

[0090] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0091] The above-described embodiments merely illustrate several implementations of the present invention, and while their descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the spirit of the present invention, all of which fall within the scope of protection of the present invention. Therefore, the scope of protection of the patent for this invention shall be determined by the appended claims.
