Implementation

[0007] Various embodiments are described in detail below; however, these embodiments are merely illustrative and do not limit the scope of the invention. Well-known elements and steps are not described in the embodiments to avoid unnecessarily limiting the scope of the invention. Furthermore, some elements are omitted from the drawings in the embodiments to clearly show the technical features of the invention. The same reference numerals will be used to denote the same or similar elements in all drawings.

[0008] Please refer to Figure 1, which is a perspective view of the drug packaging device 1 in any embodiment. The drug packaging device 1 is used to receive drugs and, together with the drugs, seal them with the medicine paper 2 shown in Figures 5 and 11 to form a medicine package 25 (as shown in Figures 15, 17, 19, and 21). The drug packaging device 1 includes a housing 10, a first heating module 20, a second heating module 40, a drug dispensing module 60, and a transmission module 80. In some embodiments, the drugs are dispensed by a drug delivery device (not shown), which dispenses the corresponding drugs according to the type and quantity of drugs to be taken each time.

[0009] The housing 10 includes a medicine paper conveying channel 12 and a medicine paper inlet side 11 and a medicine paper outlet side 13 located on both sides of the medicine paper conveying channel 12. In some embodiments, the housing 10 includes a bottom plate 101 and a side plate 103, and the side plate 103 is perpendicularly disposed on one side edge of the bottom plate 101. Furthermore, the medicine paper inlet side 11, the medicine paper conveying channel 12, and the medicine paper outlet side 13 are sequentially separated along the displacement direction P by the space formed by the bottom plate 101 and the side plate 103, as shown in FIG5.

[0010] Please refer to Figures 3 and 4. The base plate 101 includes a top surface 1011, a side surface 1012, and a channel 1013, with the side surface 1012 perpendicular to the top surface 1011. The top surface 1011 has a top opening 1011h, and the side surface 1012 has a side opening 1012h. The two ends of the channel 1013 are connected to the top opening 1011h and the side opening 1012h, respectively, and the channel 1013 is used to receive the collection box 1015. In some embodiments, the channel 1013 is located within the spatial area formed by the top surface 1011 and the side surface 1012. For example, the channel 1013 is a rectangular channel, an L-shaped channel, or a circular channel, and its cross-sectional shape is the same as or similar to the cross-section of the collection box 1015.

[0011] In some embodiments, the end of the collection box 1015 near the top opening 1011h has a ramp so that if the drug D is accidentally dropped, it can slide more easily into the box and avoid piling up in one place.

[0012] Referring to Figures 1 to 5, the first heating module 20 and the second heating module 40 are respectively disposed on the housing 10, with the first heating module 20 located on the medicine paper side 11 and the second heating module 40 located in the area of ​​the medicine paper conveying channel 12. Furthermore, the first heating module 20 and the second heating module 40 are located on opposite sides of the medicine dispensing module 60.

[0013] In some embodiments, the first heating module 20 includes a first heating element 201 and a corresponding first pressing component 202, and the first heating element 201 and the first pressing component 202 are located in the region where the medicine paper side 11 is located. For example, the first heating element 201 is located on the side plate 103 in the region where the medicine paper side 11 is located, while the first pressing component 202 is located on the bottom plate 101 in the region where the medicine paper side 11 is located. Thereby, the first heating module 20 is used to seal the side edge of the medicine paper 2 to form a side seal edge 21. For example, the first pressing component 202 is used to push the medicine paper 2 toward the direction of the first heating element 201 to seal the side edge of the medicine paper 2 to form a side seal edge 21 (as shown in FIG11).

[0014] In some embodiments, the first pushing assembly 202 includes a first driving member 2021, a first pressing piece 2022, and a first block 2023. The first driving member 2021 is connected to the first pressing piece 2022, and the first block 2023 is located between the first pressing piece 2022 and the first heating element 201. Thus, the first driving member 2021 drives the first pressing piece 2022 to push the first block 2023, displacing it towards the first heating element 201.

[0015] In some embodiments, the second heating module 40 includes a second heating element 401 and a corresponding second pressing component 402, and the second heating element 401 and the second pressing component 402 are located in the area where the medicine paper conveying channel 12 is located. For example, the second heating element 401 is located on the side plate 103 in the area where the medicine paper conveying channel 12 is located, while the second pressing component 402 is located on the bottom plate 101 in the area where the medicine paper conveying channel 12 is located. Thereby, the second heating module 40 is used to seal the opening 23 of the medicine paper 2 to form a sealed portion 231. For example, the second pressing component 402 is used to push the medicine paper 2 toward the direction of the second heating element 401 to seal the opening 23 of the medicine paper 2 to form a sealed portion 231.

[0016] In some embodiments, the second pushing assembly 402 includes a second driving member 4021, a second pressing piece 4022, and a second block 4023. The second driving member 4021 is connected to the second pressing piece 4022, and the second block 4023 is located between the second pressing piece 4022 and the second heating element 401. Thus, the second driving member 4021 drives the second pressing piece 4022 to push the second block 4023, displacing it towards the second heating element 401.

[0017] In some embodiments, the first drive member 2021 and the second drive member 4021 can be servo motors. The servo motors drive the plates (e.g., the first plate 2022 and the second plate 4022) mounted thereon to rotate, and to displace them in a manner that is vertically forward or laterally parallel.

[0018] In some embodiments, the axis of the long side of the first heating element 201 extending outward is perpendicular to the housing 10, while the axis of the long side of the second heating element 401 extending outward is parallel to the housing 10. In other words, the virtual axes of the long sides of the first heating element 201 and the second heating element 401 extending outward are perpendicular to each other.

[0019] In some embodiments, the first heating element 201 and the second heating element 401 are made of PTC electronic ceramic components. The heating temperature of the first heating element 201 and the second heating element 401 can reach 180°C. In some embodiments, the first heating element 201 and the second heating element 401 are mounted on the side plate 103 through a ceramic fiber insulating plate.

[0020] In some embodiments, the first heating module 20 further includes a first limiting member 203, and the second heating module 40 further includes a second limiting member 403. The first limiting member 203 limits the first block 2023 to the side of the dispensing module 60 and faces the area where the first heating element 201 is located, while the second limiting member 403 limits the second block 4023 to the other side of the dispensing module 60 and faces the area where the second heating element 401 is located.

[0021] Referring to Figures 1 and 2, the dispensing module 60 is located between the first heating module 20 and the second heating module 40. Referring to Figures 3 and 4, the dispensing module 60 includes a dispensing track 63 and a drug inlet 61 and a drug outlet 65 located on both sides of the dispensing track 63. In some embodiments, the dispensing module 60 is located in the area of ​​the drug paper conveying channel 12, the drug inlet 61 is located on the side of the dispensing track 63 away from the base plate 101, and the drug outlet 65 is located on the other side of the dispensing track 63 close to the base plate 101. In some embodiments, when the drug paper 2 is installed in the drug packaging device 1, the dispensing track 63 is inserted into the opening 23 of the drug paper 2 to, for example, correctly dispense the drug D into the drug paper.

[0022] In some embodiments, the dispensing module 60 further includes an extension end 62, a dispensing track 67, and a dispensing guide 64. The extension end 62 is adjacent to the outside of the drug inlet 61 away from the side plate 103. One end of the dispensing track 67 is connected to the extension end 62, and the other end is located on the base plate 101. The dispensing track 67 has a slope 671 extending toward the drug inlet 61 on the side wall adjacent to the dispensing track 63. The dispensing guide 64 is accommodated in the inner side wall of the dispensing track 63 near the drug inlet 61. The dispensing guide 64 includes a first end 641 and a second end 642 opposite to each other. The first end 641 is the end of the dispensing guide 64 disposed on the dispensing track 63 away from the drug inlet 61, and the second end 642 is the end of the dispensing guide 64 near the drug inlet 61.

[0023] In some embodiments, the dispensing module 60 further includes a dispensing drive 69 for driving the first end 641 of the dispensing guide 64 to rotate at a fixed point, thereby causing the second end 642 to move between the two opposing inner sidewalls of the inlet 61. For example, the dispensing drive 69 can be a servo motor. The servo motor drives the dispensing guide 64 connected to it to rotate, so that the dispensing guide 64 swings at the inlet 61 to close or open the inlet 61.

[0024] Referring to Figures 1 and 5, the transmission module 80, located on the dispensing side 13, drives the medicine paper 2 to move along the displacement direction P in the medicine paper conveying channel 12, and guides the sealed medicine paper 2 to move outward from the dispensing side 13. Referring to Figures 1, 3, and 4, in some embodiments, the transmission module 80 includes a guide component 81 and a fixing component 83. The guide component 81 is disposed on the housing 10, while the fixing component 83 is disposed on the housing 10 at the corresponding position of the guide component 81.

[0025] In some embodiments, the guide assembly 81 includes a stepper motor 811 and a motor roller 813, with the motor roller 813 mounted on the stepper motor 811. For example, the motor roller 813 is mounted on the stepper motor 811 via a coupling (such as a flange coupling).

[0026] In some embodiments, the fixing assembly 83 includes a fixing part 831, a fixing latch 832, and a rubber-coated roller 833. The rubber-coated roller 833 and the fixing latch 832 are mounted on the fixing part 831, with the rubber-coated roller 833 close to the motor roller 813, for clamping the medicine paper 2 between the rubber-coated roller 833 and the motor roller 813. The guiding assembly 81 displaces the medicine paper 2, positioned between the rubber-coated roller 833 and the motor roller 813, in the displacement direction P.

[0027] In some embodiments, the fixing part 831 has multiple through holes (not shown in the figures). The through holes near the side plate 103 are used to fix the fixing part 831 to the base plate 101 by screws or latches (not shown in the figures) that are locked from bottom to top. The through hole at the other end of the fixing part 831 is used to set the fixing latch 832. In other words, the fixing latch 832 passes through the through holes of the fixing part 831 and is set in the corresponding through hole grooves of the fixing part 831 and the base plate 101. In this way, when installing the medicine paper 2, the fixing latch 832 can be removed and the fixing part 831 can be rotated to provide space for the medicine paper 2 to pass between the rubber-coated roller 833 and the motor roller 813. Furthermore, after installing the medicine paper 2, the fixing latch 832 can be installed to lock the fixing part 831 onto the base plate 101, ensuring that the medicine paper 2 can be firmly locked between the rubber-coated roller 833 and the motor roller 813.

[0028] In some embodiments, the housing 10 further includes a temperature sensing element 15. The temperature sensing element 15 is located on the top surface of the side plate 103 (as shown in Figures 16, 18, 20 and 22) and is electrically connected to the first heating element 201 and the second heating element 401 to detect the temperature of each heating element.

[0029] Please refer to Figures 3 and 4. In some embodiments, the housing 10 further includes a snap fastener 105, which is vertically disposed on the other side edge of the base plate 101 opposite to the side plate 103.

[0030] Referring to Figure 2, in some embodiments, the drug packaging device 1 further includes at least one assembly housing 90. Each assembly housing 90 includes an assembly base plate 901, an assembly side plate 903, and an assembly fastener 905. The assembly side plate 903 and the assembly fastener 905 are respectively vertically disposed on two opposite side edges of the assembly base plate 901. Furthermore, the assembly fastener 905 of at least one assembly housing 90 is engaged with the fastener 105 and fixed through the mounting sleeve 951 to form an installation limiting member 95. Thereby, the installation limiting member 95 is used to install the drug roll 200. In one example, the number of assembly housings 90 is three, of which two assembly housings 90 are respectively engaged on the left and right sides of the housing 10, while the remaining assembly housing 90 is disposed on the opposite side of the housing 10 and is engaged with the other two assembly housings 90.

[0031] In some embodiments, the drug dispensing device 1 may be, but is not limited to, cylindrical or cubical. For example, when the drug dispensing device 1 is cylindrical, its diameter is 240±5 mm and its height is 105±20 mm. Therefore, its small size makes it suitable as a drug dispensing device for personal or household use. In some embodiments, when the drug delivery device and the drug dispensing device 1 are assembled and both are cylindrical, the overall height is 315±20 mm and the diameter is approximately 240±5 mm. In some embodiments, the height of the drug dispensing device 1 can be adjusted within a range of 20 mm depending on the size of the selected drug paper 2.

[0032] In some embodiments, the medicine paper 2 is made of paper with a heat-sensitive material, which can change the paper's adhesiveness through high temperature to adhere the sealing film. For example, the heat-sensitive material is hot melt adhesive, polyurethane, polyethylene, etc. In some embodiments, the medicine paper 2 is glassine coated paper.

[0033] In some embodiments, the medicine paper 2 is folded, having a bent portion (not shown in the figure) and an opening 23. As shown in FIG12, the medicine paper 2 is generally V-shaped, wherein the bent portion is one end close to the bottom plate 101 of the housing 10, and the other end away from the bottom plate 101 is the opening 23. In some embodiments, the medicine paper 2 is mounted on the drug packaging device 1 in the form of a medicine paper roll 200, as shown in FIG5.

[0034] Please refer to Figure 5. In some embodiments, the medicine roll 200 is installed on the medicine packaging device 1, and the medicine paper 2 is installed between the side plate 103 at the medicine paper inlet side 11, the medicine paper conveying channel 12, and the medicine paper outlet side 13 and the first heating module 20, the second heating module 40, the medicine dispensing module 60, and the transmission module 80. The medicine dispensing track 63 of the medicine dispensing module 60 is placed into the open opening 23 of the medicine paper 2. The remaining unopened medicine papers 2 are located sequentially between the first heating plate 201 and the first block 2023, between the side plate 103 and the medicine dispensing track 67, between the second heating plate 401 and the second block 4023, and between the rubber-coated roller 833 and the motor roller 813.

[0035] Next, referring to Figures 5 to 8, in some embodiments, the operation flow of the drug dispensing device 1 is as follows: preheating the first heating module 20 and the second heating module 40 (i.e., step S10), the transmission module 80 drives the drug paper 2 to move along the displacement direction P and perform the first positioning (i.e., step S11), the first heating module 20 seals one side of the drug paper 2 to form a first side seal 21a (i.e., step S12), the transmission module 80 drives the drug paper 2 with the side seal 21 to move along the displacement direction P and perform the second positioning (i.e., step S13), the first heating module 20 seals one side of the drug paper 2 to form a second side seal 21b to form the area of ​​the unit drug packet (i.e., step S14) and performs the detection of correct or incorrect drug dispensing (i.e., step S15). Next, the drug dispensing device 1 will determine whether the amount of drug dispensed is correct (i.e., step S16). If the amount is correct, the transmission module 80 will drive the drug paper 2 containing the drug D to move along the displacement direction P and perform a third positioning (i.e., step S17). Otherwise, if the amount is incorrect, the drug dispensing drive 69 will be activated (i.e., step S20).

[0036] Following step S17, after the drug dispensing device 1 determines that the amount of drug dispensed is correct and performs a third displacement, the second heating module 40 seals the opening 23 of the drug paper 2 containing drug D to form a sealed portion 231 (i.e., step S18), resulting in a drug package 25 with three-sided sealing. Then, it returns to step S14, where the side sealing edge 21 and the area of ​​the new unit drug package are generated, and then continues to step S15 to determine whether the amount of drug dispensed is correct, until the drug is completely dispensed. After the drug dispensing and dispensing, the drug paper 2 will also form a series of continuously sealed drug packages 25.

[0037] Following step S20, after the drug dispensing device 1 determines that the amount of drug dispensed is incorrect, it activates the dispensing drive 69. The dispensing drive 69 drives the first end 641 of the dispensing guide 64 to rotate at a fixed point, causing the second end 642 to move towards the inner wall of the inlet 61 away from the dispensing track 67 (i.e., step S21). The incorrectly dispensed drug D enters the dispensing track 67 along the dispensing guide 64 and falls into the collection box 1015 (i.e., step S22). Then, it returns to step S15. After the new drug D is dispensed, the drug dispensing device 1 again determines whether the amount of drug dispensed is correct.

[0038] In some embodiments, the drug dispensing device 1 has a detection module 300 above the drug dispensing module 60 (as shown in Figures 15 to 22). The detection module 300 is used to determine whether the quantity of drug D entering the drug dispensing module 60 is correct, in order to determine whether the subsequent drug dispensing is correct or incorrect. For example, the detection module 300 can be a photosensitive module, but is not limited to this. When drug D falls, it passes through the sensing area of ​​the detection module 300, thereby sensing the drug D entering the drug dispensing track 63 through the signal sensed by the detection module 300. In some embodiments, the photosensitive module is a contrast-type infrared detector, which determines that a drug D has passed when the detected infrared light is blocked. If the number of drugs D that fall is the preset number, it will be judged as a correct distribution, and drugs D will fall into the medicine paper 2 along the correct falling trajectory CP; conversely, if the number of drugs D that fall is less or more than the preset number, it will be judged as an incorrect distribution, and drugs D will fall into the collection box 1015 along the incorrect falling trajectory RP.

[0039] In some embodiments, the detection module 300 is located at the outlet of the drug delivery device or is disposed on the outer edge of the drug packaging device 1 (such as the drug inlet 61).

[0040] Referring to Figure 9, in some embodiments, the first heating module 20 and the second heating module 40 are in a preparatory state before sealing. The medicine paper 2 is positioned between the first block 2023 and the second block 4023 and the first heating element 201 and the second heating element 401 on the side plate 103, respectively. In the preparatory state, the medicine paper 2 does not contact the first heating element 201 and the second heating element 401, and neither the first pressing component 202 nor the second pressing component 402 applies force to the medicine paper 2. In some embodiments, the first pressing element 2022 abuts against the first block 2023, and the second pressing element 4022 abuts against the second block 4023, but neither applies force to the first block 2023 or the second block 4023. In other embodiments, the first pressing element 2022 approaches but does not contact the first block 2023, and the second pressing element 4022 approaches but does not contact the second block 4023.

[0041] Please refer to Figure 10. The first heating module 20 and the second heating module 40 are in the sealing operation state. The first block 2023 and the second block 4023 push the medicine paper 2 towards the first heating plate 201 and the second heating plate 401 respectively for sealing. Specifically, the first pressing plate 2022 rotates forward in the first rotation direction R1, abutting against the first block 2023 and providing a pushing force towards the side plate 103, pushing the first block 2023 towards the first heating plate 201; the second pressing plate 4022 rotates forward parallel in the second rotation direction R2, abutting against the second block 4023 and providing a pushing force towards the side plate 103, pushing the second block 4023 towards the second heating plate 401. After a preset sealing time, the first heating module 20 and the second heating module 40 will reset to the ready state.

[0042] Referring again to Figures 9 and 10, in some embodiments, a first spring 207 is installed inside the first block 2023, and a second spring 407 is installed inside the second block 4023. When the first pressing plate 2022 applies force to the first block 2023, the first spring 207 inside it is compressed, and when the second pressing plate 4022 applies force to the second block 4023, the second spring 407 inside it is compressed. The first spring 207 and the second spring 407 respectively provide the elastic force for the first block 2023 and the second block 4023 to return to their ready positions.

[0043] Please refer to Figures 11 to 14. Figure 11 is a schematic diagram of the preparatory state of the drug packaging device 1 in any embodiment; Figure 12 is a schematic diagram of the sealing state of the drug paper 2 of the drug packaging device 1 in any embodiment (I); Figure 13 is a schematic diagram of the sealing state of the drug paper 2 of the drug packaging device 1 in any embodiment (II); and Figure 14 is a schematic diagram of the sealing state of the drug paper 2 of the drug packaging device 1 in any embodiment (III). After the drug packaging device 1 completes the preheating in step S10, the first positioning in step S11, and the first side sealing edge 21a in step S12 (corresponding to the side sealing edge 21 in Figure 11), the drug packaging device 1 performs step S13 to cause the guide component 81 of the transmission module 80 to drive the drug paper 2 with the side sealing edge 21 to move along the displacement direction P for the second positioning, as shown in Figure 15. Next, the drug packaging device 1 performs step S14 to form a second side seal 21b (corresponding to the side seal 21 in Figure 14) on one side of the first heating module 20 sealing the drug paper 2, thus forming the area of ​​the unit drug packet. Step S15 is then performed to detect correct or incorrect drug dispensing, as shown in Figure 12. When the quantity of drug D is correct, drug D will correctly fall into the area of ​​the unit drug packet, as shown in Figure 13. Next, the drug packaging device 1 performs a third positioning step S17, and then performs step S18 to seal the opening 23 of the drug paper 2 containing drug D with the second heating module 40, forming a sealed portion 231, as shown in Figure 14. Thus, when the unit drug packet containing drug D is completely sealed on three sides, it becomes drug packet 25 (as shown in Figures 15, 17, 19, and 21).

[0044] Following step S16, it is determined whether the amount of medicine dispensed is correct. If the amount of medicine dispensed is correct, steps S17 and S18 will be performed to ensure correct dispensing. Please refer to Figures 15 to 18, where Figure 15 is a three-dimensional schematic diagram (I) of the correct dispensing state of the local drug dispensing device 1 in any embodiment, Figure 16 is a side view (I) of Figure 15, Figure 17 is a three-dimensional schematic diagram (II) of the correct dispensing state of the local drug dispensing device 1 in any embodiment, and Figure 18 is a side view (II) of Figure 17.

[0045] Please refer to Figures 15 and 16. In some embodiments, the quantity of drug D dropped into the area where the detection module 300 is located is determined. Since the drug dispensing device 1 does not accept the judgment of incorrect drug dropping, the dispensing drive 69 will not be activated. The first end 641 of the dispensing guide 64 does not rotate, and its second end 642 abuts against the inner wall of the inlet 61 near the extension end 62. Therefore, the dispensing guide 64 covers the opening of the dispensing track 67 with the inclined surface 671 to prevent drug D from falling into the dispensing track 67. Then, drug D will fall into the area of ​​the unit drug packet formed by the drug paper 2 with the correct dropping trajectory CP, as shown in Figures 17 and 18.

[0046] Following step S16, it is determined whether the amount of medicine dispensed is correct. If the amount of medicine dispensed is incorrect, steps S20 to S22 will be performed. Please refer to Figures 19 to 22, where Figure 19 is a three-dimensional schematic diagram (I) of the incorrect dispensing state of the local drug dispensing device 1 in any embodiment, Figure 20 is a side view of Figure 19 (I), Figure 21 is a three-dimensional schematic diagram (II) of the incorrect dispensing state of the local drug dispensing device 1 in any embodiment, and Figure 22 is a side view of Figure 21 (II).

[0047] Please refer to Figures 19 and 20. In some embodiments, the quantity of drug D dropped in the area where the detection module 300 is located is determined. When the drug dispensing device 1 receives the determination of incorrect drug dropping, it activates the dispensing drive 69. The dispensing drive 69 drives the first end 641 of the dispensing guide 64 to rotate, and drives the second end 642 to abut against the inner sidewall of the drug inlet 61 near the side plate 103. Therefore, the dispensing guide 64 covers the opening of the drug dropping track 63, so that the drug D can fall into the dispensing track 67 along the dispensing guide 64. Then, the drug D will fall into the collection box 1015 in the lower base plate 101 along the incorrect drug dropping trajectory RP, as shown in Figures 21 and 22.

[0048] Please refer to Figure 23, which is a circuit diagram of the drug dispensing device 1 in any embodiment.

In some embodiments, the network module 530 is used to transmit the current status of the drug dispensing device 1 to the electronic device, allowing the user to know the current status of the drug dispensing device 1, such as whether the drug was dispensed correctly or incorrectly, or to provide other information (such as a pill pad 2 level detector) in conjunction with other sensors (such as a pill pad 2 depletion reminder).

[0053] The display module 550 is located on the outer surface of the housing 10. The display module 550 is coupled to the first controller 511, so that the first controller 511 can display information via the display module 550. In some embodiments, the display module 550 is used to display the current status of the drug dispensing device 1, such as correct drug dispensing, incorrect drug dispensing, or the drug paper 2 being exhausted.

[0054] A blood oxygen sensing module 540 is coupled to a first controller 511 for the user to measure blood oxygen parameters. The blood oxygen sensing module 540 is located near the dispensing strip side 13, facilitating blood oxygen parameter measurement when the user picks up the medication pack 25. The measured blood oxygen parameters can be displayed on a display module 550 and / or transmitted to an electronic device for recording via a network module 530.

[0055] The sound module 560 is coupled to the first controller 511 and is controlled by the first controller 511 to output sound (such as warning tone, voice, etc.) to guide the user in operating the drug dispensing device 1 and / or to inform the user of the current status of the drug dispensing device 1. The sound module 560 is a sound output element such as a buzzer or a speaker.

[0056] The first switch 571 and the second switch 572 are coupled to the first controller 511 so that the user can trigger the drug dispensing device 1 to perform corresponding functions. For example, the first switch 571 can enable or disable the network module 530, and the second switch 572 can restart the drug dispensing device 1. In some embodiments, the first switch 571 and the second switch 572 are located on the outer surface of the housing 10.

[0057] In summary, the drug dispensing device of any embodiment can automatically package drugs into paper-sealed packages. Furthermore, a first / second heating element can continuously seal the paper into drug-filled packets. In some embodiments, the drug dispensing device can determine the amount of medication dispensed and detect correct and incorrect dispensing to avoid waste from incorrectly packaged medication and reduce the possibility of users taking the wrong medication.
