Abstract
Description
Technical Field
[0001] This utility model relates to the field of biomedical engineering industry, specifically to a drug delivery system. Background Technology
[0002] A smart home medicine dispenser (or simply medicine dispenser) is a health device that automatically dispenses medications. Its functions generally include medication storage, medication dispensing, and timed medication reminders. Specifically, by automating the storage, dispensing, and quantitative distribution of medications, the medicine dispenser helps users take their medications on time and in the correct dosage, effectively reducing the occurrence of missed or incorrect doses.
[0003] A medicine storage unit typically has the following structure: medicine storage boxes for storing medicines and a transport mechanism for transporting medicines. Medicines fall from the medicine storage boxes into the transport mechanism through the dispensing port, and then different types and quantities of medicines can be transported to predetermined locations (e.g., locations where medicines can be easily accessed) by controlling the transport mechanism.
[0004] However, when drugs enter the delivery mechanism directly from the storage section, blockages or jams are very likely to occur. Multiple drugs may stack and squeeze each other at the inlet, hindering the entry of subsequent drugs and causing drug administration interruption, which seriously affects the reliability and operational efficiency of the drug storage. Summary of the Invention
[0005] This invention was proposed in view of the above-mentioned situation, and its purpose is to provide a drug delivery system that can improve reliability.
[0006] Therefore, this utility model provides a drug delivery system, including a drug storage section for storing drugs, a drug delivery mechanism for transporting drugs, and a sieve plate. The drug storage section includes a drug inlet for providing drugs. The delivery mechanism includes a housing and a rotating part disposed on the housing and having a receiving groove. The housing has a drug inlet that matches the drug supply port and a drug outlet configured to release drugs. The rotating part rotatably rotates the receiving groove to a first position that matches the drug inlet and rotates the receiving groove from the first position to a second position that matches the drug outlet. The sieve plate is disposed between the drug storage section and the delivery mechanism in a fixed manner to the housing and has sieve holes aligned with the drug supply port and the drug inlet. The size of the sieve holes matches the size of the drugs.
[0007] In this invention, the medicine in the storage unit enters the receiving tank through the drug supply port and the inlet port of the casing. The rotating part rotates the receiving tank from a first position to a second position, thereby releasing the medicine from the receiving tank through the outlet. The transport mechanism transports the medicine by rotating the rotating part, which helps to make the structure of the transport mechanism more compact compared to translation. In addition, by setting a sieve plate between the storage unit and the transport mechanism, the sieve plate can easily restrict the medicine supplied from the storage unit to the transport mechanism; by matching the size of the sieve holes with the size of the medicine, the movement of the medicine can be restricted, thereby ensuring that the medicine is received at the intended position of the transport mechanism, reducing the impact of the medicine on the normal operation of the transport mechanism, and thus improving the reliability of the drug delivery system.
[0008] Furthermore, in the drug delivery system of this invention, the gap between the inner edge of the housing and the outer edge of the rotating part is smaller than the size of a single drug capsule. This reduces the likelihood of the drug entering between the inner edge of the housing and the outer edge of the rotating part, thus affecting the normal rotation of the rotating part.
[0009] Furthermore, in the drug delivery system of this invention, the size of the receiving slot is matched to the size of a single drug capsule. This facilitates the individual capsule dropping of the drug, making dosage calculation easier.
[0010] Furthermore, in the drug delivery system of this invention, there are multiple receiving slots, which are evenly arranged around the periphery of the rotating part. In this case, the included angles between the various receiving slots are the same, and each fixed angle rotation of the rotating part allows the drug in one receiving slot to be received and / or released, thereby facilitating the control of the drug dosage by controlling the rotation angle of the rotating part.
[0011] Furthermore, in the drug delivery system of this invention, there are multiple drug storage units, and the delivery mechanism includes multiple rotating parts that match the multiple drug storage units. The housing has multiple drug inlets that match the multiple drug storage units. In this case, multiple drug storage units can facilitate the storage of various drugs, thereby expanding the applicability of the drug delivery system. In addition, the multiple rotating parts match the multiple drug storage units, and different rotating parts can receive different drugs from different drug storage units, thereby facilitating the delivery mechanism to deliver different quantities of different drugs as needed.
[0012] Furthermore, in the drug delivery system of this utility model, the rotating part is a gear, and the receiving groove is a toothed groove.
[0013] Furthermore, the drug delivery system of this invention also includes sensors disposed at the drug inlet and / or the drug outlet, the sensors being configured to detect whether a drug has passed through. In this case, by sensing the drug passing through the drug inlet or the drug outlet, it is convenient to calculate the amount of drug delivered by the drug delivery system. Additionally, by sensing the drug passing through both the drug inlet and the drug outlet, it is convenient to obtain the amount of drug in the delivery mechanism.
[0014] Furthermore, in the drug delivery system of this invention, the size of the drug inlet is larger than the size of the sieve aperture. This reduces the possibility of the drug clogging the drug inlet.
[0015] Furthermore, in the drug delivery system of this invention, the drug reservoir is configured to move relative to the sieve plate in a manner that allows it to abut against the sieve plate. During this movement, the drug inlet moves relative to the sieve plate, at least partially overlapping the sieve holes. In this case, by having the drug reservoir abut against the sieve plate, the gap between the drug reservoir and the sieve plate can be reduced, thereby decreasing the possibility of the drug falling out through the gap. Additionally, by allowing the drug reservoir to move relative to the sieve plate, it facilitates the passage of the drug in the reservoir through the sieve holes. Furthermore, by having the drug inlet at least partially overlap the sieve holes during relative movement, it further facilitates the passage of the drug through the sieve holes.
[0016] Furthermore, the drug delivery system of this invention also includes a drive mechanism configured to drive the drug reservoir, the drive mechanism comprising a motor and / or a crank-connecting rod mechanism. In this case, since the drug in the reservoir may not spontaneously pass through the sieve holes, driving the drug reservoir relative to the sieve plate allows the drug reservoir to exert an action on the drug, causing the drug to move and thus facilitating its passage through the sieve holes. Additionally, by driving the drug reservoir and thus driving the drug within it, the drug can move relative to the sieve holes, reducing the possibility of the drug clogging the sieve holes.
[0017] According to this invention, a drug delivery system that can improve reliability is provided. Attached Figure Description

[0031] First, the relevant terminology involved in this utility model will be introduced.
[0032] "Administration" can refer to the administration of medicine.
[0033] "Accuracy of a drug delivery system" can refer to how closely the quantity and type of medication actually administered by the system matches the quantity and type of medication preset by the user. For example, the closer the actual amount of medication administered is to the preset amount, the higher the accuracy of the drug delivery system.
[0034] The drug delivery system described in this utility model, through the cooperation of the drug storage unit and the delivery mechanism, can deliver drugs and impose restrictions on the drugs, thereby reducing the impact of the drugs on the normal operation of the delivery mechanism and improving the reliability of the drug delivery system.
[0035] In some examples, the drug delivery system involved in this utility model may also be referred to as a drug dispensing system, a drug preparation system, a drug delivery device, a drug administration device, or a drug storage container, etc.
[0036] In some examples, the dosage form of the drug may be at least one of tablets, capsules, and pills. In other examples, the dosage form of the drug may also be a liquid dosage form, a powder, and / or an extract dosage form, etc.
[0037] The drug delivery system involved in this utility model will be described in detail below with reference to the accompanying drawings.
[0038] Figure 1 This is a diagram illustrating an application scenario of the drug delivery system 1 involved in this utility model example.
[0039] In some examples, the drug delivery system 1 can be configured to administer medication. Administering medication can refer to preparing medication according to the user's needs for the type and quantity of medication, and providing the prepared medication to the user.
[0040] In some examples, the drug delivery system 1 can be configured to receive instructions. These instructions may contain information about the type and quantity of the medication. Upon receiving the instructions, the drug delivery system 1 can administer the medication. In some examples, the instructions may be generated and sent by the user.
[0041] In some examples, instructions can be sent via external device 1 (see [link]). Figure 1 External device 1 can be operated by the user.
[0042] See in some examples Figure 1 The drug delivery system 1 may include a display screen 11. In some examples, instructions can also be sent to the drug delivery system 1 by operating the display screen 11.
[0043] See in some examples Figure 1 The drug delivery system 1 may include a drug dispensing unit 15. The drug dispensing unit 15 may be configured to provide medicine to the user. This makes it convenient for the user to obtain the medicine.
[0044] In some examples, when a user takes a medication, the display screen 11 can show the type and quantity of medication in the dispensing unit 15. This helps the user verify whether the type and quantity of medication dispensed by the drug delivery system 1 meet their needs.
[0045] In some examples, the instructions may also include the time of medication (or administration). The drug delivery system 1 can prepare the medication to be administered before the scheduled time.
[0046] In some examples, the drug delivery system 1 can remind the user to take the medication before or at the scheduled time. For example, the reminder can be given by sending a reminder message to an external device 2 and / or by emitting a sound to remind the user.
[0047] Figure 2A This is a schematic diagram showing the internal structure of the drug delivery system 1 involved in this utility model example. Figure 2B It shows Figure 2A A cross-sectional view of the Chinese medicine drug delivery system 1 along the XX direction.
[0048] See in some examples Figure 2A The drug delivery system 1 may include a drug storage unit 12. In some examples, the drug storage unit 12 may be configured to store a drug.
[0049] In some examples, the medicine can be added (e.g., manually) to the medicine storage section 12.
[0050] In some examples, the number of medicine storage sections 12 can be one.
[0051] See in some examples Figure 2A The number of drug storage sections 12 can also be multiple. For example, the number of drug storage sections 12 can be 2, 3, 4 or 5, etc. In this case, multiple drug storage sections 12 can facilitate the storage of a variety of drugs, thereby expanding the applicability of the drug delivery system 1.
[0052] In some examples, each medicine storage unit 12 can store the same or different kinds of medicines.
[0053] In some examples, the medicine storage compartment 12 may include a cover. The cover may be configured to seal the internal space of the medicine storage compartment 12. This reduces the contamination of the medicine in the medicine storage compartment 12 by external factors (such as dust or moisture).
[0054] The cover can be open during the addition of medication. In other words, the cover can remain in the unsealed internal space of the medication storage compartment 12. This facilitates the addition of medication.
[0055] In some examples, the cover can be in a closed state during the operation of the drug delivery system 1. In other words, the cover can be in a state of sealing the internal space of the drug storage section 12.
[0056] See in some examples Figure 2B The drug storage unit 12 may include a drug dispensing port 121. In some examples, the drug dispensing port 121 may be configured to dispense drugs. In some examples, the drugs in the drug storage unit 12 may leave the drug storage unit 12 via the drug dispensing port 121.
[0057] See in some examples Figure 2A or Figure 2B The drug delivery system 1 may include a delivery mechanism 13.
[0058] In some examples, delivery mechanism 13 can be configured to receive medicines. In some examples, delivery mechanism 13 can receive medicines supplied by medicine supply port 121.
[0059] In some examples, the delivery mechanism 13 can also be configured to deliver medicines. In some examples, the delivery mechanism 13 can deliver received medicines (such as medicines supplied by the dispensing port 121) to a releasable location (described in detail later).
[0060] In some examples, the transport mechanism 13 can also be configured to release the medicine. In some examples, the transport mechanism 13 can release the medicine after it has been transported to a releaseable location. The transport mechanism 13 can release the medicine to the dispensing unit 15.
[0061] See in some examples Figure 2B The transport mechanism 13 may include a rotating part 131. The rotating part 131 may be configured to receive, transport and release medicines.
[0062] In some examples, the rotating part 131 can rotate. In this case, the transport mechanism 13 transports the medicine by rotating the rotating part 131, which helps to make the structure of the transport mechanism 13 more compact compared to translation. The rotating part 131 can receive, transport and release medicine in a rotating manner.
[0063] In some examples, the rotating part 131 may have a receiving groove 1311 (see Figure 2B The receiving tank 1311 can be configured to receive medicines. In other words, medicines can be received in the receiving tank 1311 or the receiving tank 1311 can receive medicines.
[0064] In some examples, the receiving tank 1311 can rotate with the rotating part 131 to transport medicines. In some examples, medicines can be transported in a manner that allows them to be contained in the receiving tank 1311.
[0065] In some examples, the medicine can be released from the receiving tank 1311 when it is transported to a releasable location.
[0066] In some examples, the size of the receiving slot 1311 can match the size of a single medicine. Specifically, the size of the receiving slot 1311 can be equal to or slightly larger than the size of a single medicine. In this case, it helps to allow the medicine to fall one by one, thus facilitating the calculation of the dosage. It should be noted that "slightly larger than the size of a single medicine" can mean larger than the size of a single medicine but smaller than the size of two medicines, that is, one receiving slot 1311 can only hold one medicine.
[0067] In other examples, a single container 1311 can also hold multiple medicines. This improves the efficiency of medicine delivery.
[0068] See in some examples Figure 2B The number of receiving slots 1311 can be multiple. This makes it convenient to transport multiple medicines at the same time.
[0069] In some examples, when there are multiple receiving slots 1311, the multiple receiving slots 1311 can be evenly arranged around the periphery of the rotating part 131. In this case, the included angle between each receiving slot 1311 is the same, and each time the rotating part 131 rotates by a fixed angle, the medicine in one receiving slot 1311 can be received and / or released, thereby making it easy to control the amount of medicine by controlling the rotation angle of the rotating part 131.
[0070] In other examples, the number of receiving slots 1311 may also be one.
[0071] See in some examples Figure 2B The rotating part 131 can be a gear. The receiving groove 1311 can be a tooth groove.
[0072] See in some examples Figure 2B The transport mechanism 13 may include a housing 132. In some examples, a rotating part 131 may be provided on the housing 132. This reduces the impact of external factors (such as dust or moisture) on the medicine and reduces the possibility of the medicine being released prematurely (e.g., before being transported to a releaseable location).
[0073] In some examples, housing 132 may have a drug inlet 1321 (see Figure 2BIn some examples, the inlet 1321 can provide a channel for the transport mechanism 13 to receive medication. In some examples, the inlet 1321 can be matched with the dispensing port 121. In some examples, matching the inlet 1321 with the dispensing port 121 can mean that the inlet 1321 is aligned with the dispensing port 121. This facilitates the transport mechanism 13 in receiving the medication provided by the dispensing port 121.
[0074] As described above, the rotating part 131 is rotatable. In some examples, the rotating part 131 can rotatably rotate the receiving tank 1311 to a first position. In some examples, the first position can be matched with the drug inlet 1321. In some examples, the first position matching the drug inlet 1321 can mean that when the receiving tank 1311 is in the first position, the opening of the receiving tank 1311 is aligned with the drug inlet 1321. Thus, it is convenient for the receiving tank 1311 (or the conveying mechanism 13) to receive the medicine.
[0075] In some examples, housing 132 may have a dispensing port 1322 (see [reference]). Figure 2B In some examples, the dispensing port 1322 can be configured to release medication. In some examples, the dispensing port 1322 can provide a channel for medication to leave the transport mechanism 13.
[0076] In some examples, the rotating part 131 can rotatably rotate the receiving tank 1311 to a second position. In some examples, the second position can match the dispensing port 1322. In some examples, the second position matching the dispensing port 1322 can mean that when the receiving tank 1311 is in the second position, the opening of the receiving tank 1311 is aligned with the dispensing port 1322. This facilitates the dispensing of medicine by the receiving tank 1311 (or the conveying mechanism 13).
[0077] In some examples, the rotating part 131 can rotatably rotate the receiving tank 1311 from a first position to a second position. In some examples, the rotating part 131 can also rotatably rotate the receiving tank 1311 from a second position to a first position. In this invention, the medicine in the medicine storage part 12 can enter the receiving tank 1311 through the medicine supply port 121 and the medicine inlet 1321 of the housing 132. The rotating part 131 can rotate the receiving tank 1311 from the first position to the second position, thereby causing the medicine in the receiving tank 1311 to be released by the medicine outlet 1322.
[0078] See in some examples Figure 2BThe rotating part 131 can rotate along the D1 direction to rotate the receiving groove 1311 from the first position to the second position and from the second position to the first position. In other examples, the rotating part 131 can also rotate along the D1 direction to rotate the receiving groove 1311 from the first position to the second position, and rotate the receiving groove 1311 from the second position to the first position in a direction opposite to the D1 direction.
[0079] See in some examples Figure 2B The inlet 1321 can be located at the top of the housing 132. The outlet 1322 can be located at the bottom of the housing 132. The top and bottom of the housing 132 can be divided by a dividing line L. This allows the medicine to easily enter the transport mechanism 13 (or the receiving tank 1311) through the inlet 1321 by its own weight and leave the transport mechanism 13 (or the receiving tank 1311) through the outlet 1322.
[0080] See in some examples Figure 2B There may be a gap between the inner edge of the housing 132 and the outer edge of the rotating part 131. In some examples, the gap between the inner edge of the housing 132 and the outer edge of the rotating part 131 may be smaller than the size of a single drug. This reduces the possibility of the drug entering between the inner edge of the housing 132 and the outer edge of the rotating part 131 and affecting the normal rotation of the rotating part 131.
[0081] In some examples, the gap between the inner edge of the housing 132 and the outer edge of the rotating part 131 can be set as needed. It is understood that the smaller the gap, the greater the possibility of the rotating part 131 and the housing 132 getting stuck, while the larger the gap, the greater the possibility of the medicine being damaged. Therefore, the size of the gap can be determined based on factors such as the size of the medicine, the processing accuracy, and the assembly accuracy.
[0082] As described above, there can be multiple drug storage sections 12. In some examples, there can also be multiple rotating sections 131. Multiple rotating sections 131 can be matched with multiple drug storage sections 12. In some examples, multiple rotating sections 131 matching multiple drug storage sections 12 may mean that one rotating section 131 transports only the drug from one drug storage section 12. In this case, multiple rotating sections 131 are matched with multiple drug storage sections 12, and different rotating sections 131 can receive drugs from different drug storage sections 12, thereby facilitating the transport mechanism 13 to transport different quantities of different drugs as needed. In addition, multiple rotating sections 131 transporting drugs simultaneously can improve the efficiency of drug transport. Furthermore, compared to one rotating section 131 transporting drugs from multiple drug storage sections 12, the accuracy of the drug delivery system 1 can be improved.
[0083] In some examples, the housing 132 may have multiple drug inlets 1321. In some examples, the multiple drug inlets 1321 may mate with multiple drug storage sections 12. In some examples, the multiple drug inlets 1321 may mate with multiple rotating sections 131. This facilitates the accurate reception of the drug in each drug storage section 12 by the mating drug inlet 1321 into the mating rotating section 131. In some examples, mating of multiple drug inlets 1321 with multiple drug storage sections 12 may mean that one drug inlet 1321 is aligned with the drug dispensing port 121 of only one drug storage section 12. Matching of multiple drug inlets 1321 with multiple rotating sections 131 may mean that one rotating section 131 receives the drug from only one drug inlet 1321.
[0084] In some examples, the housing 132 may also have multiple dispensing ports 1322. The multiple dispensing ports 1322 may be matched with multiple rotating parts 131.
[0085] In other examples, a single rotating part 131 can also transport medicines from multiple medicine storage sections 12. Specifically, the housing 132 may have multiple medicine inlets 1321 aligned with multiple medicine dispensing ports 121, and the openings of various receiving slots 1311 on the rotating part 131 may face different medicine inlets 1321. This facilitates the transport of medicines from multiple medicine storage sections 12 via a single transport part.
[0086] In other examples, multiple rotating sections 131 can also transport medicines from the same medicine storage section 12. This improves the efficiency of medicine transport.
[0087] In some examples, the drug delivery system 1 may include a sieve plate 14 (see Figure 2A or Figure 2B In some examples, the sieve plate 14 can be configured to restrict the drug. For example, the sieve plate 14 can confine the drug within the drug storage section 12. Alternatively, the sieve plate 14 can limit the quantity of drug dispensed at a single time by the dispensing port 121. Or, the sieve plate 14 can restrict the movement of the drug. In this case, restricting the drug by the sieve plate 14 reduces the impact of the drug on the normal operation of the drug storage section 12 or the delivery mechanism 13, thereby improving the reliability of the drug delivery system 1.
[0088] See in some examples Figure 2A or Figure 2B The sieve plate 14 can be disposed between the medicine storage section 12 and the transport mechanism 13. This allows the sieve plate 14 to impose restrictions on the medicine supplied from the medicine storage section 12 to the transport mechanism 13.
[0089] See in some examples Figure 2BThe medicine storage section 12, the sieve plate 14, and the conveying mechanism 13 can be arranged along the direction of gravity G. In other words, the medicine storage section 12, the sieve plate 14, and the conveying mechanism 13 can be arranged from top to bottom. This allows the medicine to fall from the medicine storage section 12 under its own weight and enter the conveying mechanism 13 through the sieve holes 141.
[0090] In some examples, the sieve plate 14 can be fixed to the housing 132. The sieve plate 14 can be disposed between the drug storage section 12 and the transport mechanism 13 in a manner fixed to the housing 132. In this case, by fixing the sieve plate 14 to the housing 132, the sieve holes 141 (described later) and the drug inlet 1321 can be kept aligned during drug transport.
[0091] In some examples, the sieve plate 14 can be detachably fixed to the housing 132. In this case, it is easy to replace the sieve plate 14 of different sizes (e.g., different sizes of sieve holes 141) according to the size of the medicine in the medicine storage section 12, thereby expanding the applicability of the drug delivery system 1.
[0092] See in some examples Figure 2B The sieve plate 14 may have sieve holes 141.
[0093] In some examples, the sieve aperture 141 can be configured to restrict the passage of the medicine. In some examples, restricting the medicine may mean that the medicine supplied by the medicine storage section 12 passes through the sieve aperture 141.
[0094] In some examples, the medicine supplied by the medicine storage section 12 can be received at a predetermined position on the transport mechanism 13 after passing through the sieve aperture 141. In some examples, the predetermined position can be a first position, that is, the position of the receiving tank 1311 when the opening of the receiving tank 1311 is aligned with the medicine inlet 1321. In this case, restricting the medicine through the sieve aperture 141 can help the receiving tank 1311 to accurately receive the medicine.
[0095] See in some examples Figure 2B The sieve aperture 141 can be aligned with the drug supply port 121. This allows the medicine supplied by the drug supply port 121 to pass through the sieve aperture 141 easily.
[0096] See in some examples Figure 2B The sieve aperture 141 can be aligned with the drug inlet 1321. This facilitates the receipt of the drug passing through the sieve aperture 141 into the transport mechanism 13.
[0097] In some examples, the number of sieve plates 14 can be multiple (see [reference]). Figure 2A Each sieve plate 14 may have a sieve hole 141, and each sieve hole 141 may be aligned with a different drug supply port 121 and a different drug inlet 1321.
[0098] In other examples, the number of sieve plates 14 may also be one. A sieve plate 14 may have multiple sieve holes 141.
[0099] Figure 3A This is a schematic diagram showing the structure of the first embodiment of the sieve plate 14 involved in this utility model example. Figure 3B This is a schematic diagram showing the structure of the second embodiment of the sieve plate 14 involved in this utility model example.
[0100] In some examples, the size of the sieve aperture 141 can be matched with the size of the drug. In this case, by matching the size of the sieve aperture 141 with the size of the drug, it is possible to limit the movement of the drug so that the drug is received at the intended location of the delivery mechanism 13 (e.g., the drug inlet 1321 of the delivery mechanism 13), reduce the impact of the drug on the normal operation of the delivery mechanism 13, and thereby improve the reliability of the drug delivery system 1.
[0101] In some examples, matching the size of the sieve aperture 141 to the size of the drug can mean that the size of the sieve aperture 141 is equal to or slightly larger than the size of a single drug particle. In this case, see [reference needed]. Figure 3A Sieve aperture 141 allows only one drug to pass through at a time; see also... Figure 3B Matching can also mean that the size of the sieve aperture 141 is equal to or greater than the size of multiple drugs. In this case, the sieve aperture 141 allows multiple drugs to pass through at the same time, and the shape of the sieve aperture 141 can simultaneously restrict multiple drugs.
[0102] In some examples, restricting the movement of the drug can refer to restricting the trajectory of the drug. In some examples, when the size of the sieve aperture 141 matches the size of the drug, the drug passing through the sieve aperture 141 can move along a predetermined trajectory (e.g., it can move along the direction of gravity). This facilitates the receiving of the drug at the intended position in the transport mechanism 13.
[0103] See in some examples Figure 2B The size of the drug supply port 121 can be larger than the size of the sieve aperture 141. This reduces the possibility of the drug clogging the drug supply port 121. In addition, it makes it easier for the sieve aperture 141 to restrict the drug supplied through the drug supply port 121.
[0104] In some examples, the drug reservoir 12 can be configured to move relative to the sieve plate 14. In this case, by making the drug reservoir 12 movable relative to the sieve plate 14, it is possible to facilitate the passage of the drug in the drug reservoir 12 through the sieve holes 141.
[0105] In some examples, the drug reservoir 12 can abut against the sieve plate 14. In this case, by abutting against the sieve plate 14, the gap between the drug reservoir 12 and the sieve plate 14 can be reduced, thereby reducing the possibility of the drug falling out from the gap between the drug reservoir 12 and the sieve plate 14.
[0106] In other examples, a gap may also exist between the drug reservoir 12 and the sieve plate 14. The size of the gap is smaller than the size of a single drug capsule. This reduces the negative impacts (such as component wear, vibration, and noise) caused by the friction between the drug reservoir 12 and the sieve plate 14.
[0107] In some examples, the drug reservoir 12 can be configured to move relative to the sieve plate 14 in a manner that allows it to abut against the sieve plate 14.
[0108] In some examples, during the movement of the drug reservoir 12 relative to the sieve plate 14, the drug inlet 121 may move relative to the sieve aperture 141 in a manner that at least partially overlaps with the sieve aperture 141. In this case, by making the drug inlet 121 at least partially overlap with the sieve aperture 141 during relative movement, it is possible to further facilitate the passage of the drug through the sieve aperture 141.
[0109] In some examples, the overlapping portion of the dispensing port 121 and the sieve aperture 141 allows at least one drug to pass through. For example, the overlapping area of the dispensing port 121 and the sieve aperture 141 can be equal to or slightly larger than the size of a single drug. In this case, since the drug can only leave the drug storage section 12 from the overlapping portion of the dispensing port 121 and the sieve aperture 141, it is convenient for the drug to pass through the dispensing port 121 and the sieve aperture 141 sequentially.
[0110] As mentioned above, see Figure 2A or Figure 2B The drug delivery system 1 may include a drug dispensing unit 15. The drug dispensing unit 15 may be configured to provide medicine to a user.
[0111] See in some examples Figure 2B The dispensing section 15 can be connected to the dispensing port 1322. This allows the medicine released from the dispensing port 1322 to easily enter the dispensing section 15.
[0112] See in some examples Figure 2B The medication dispensing unit 15 may include a medication dispenser 151. The medication dispenser 151 may be configured to dispense medication to the user.
[0113] In some examples, the dispensing unit 15 may include a catheter. The catheter may be configured to guide medication into the dispensing cartridge 151. In some examples, the catheter may connect the dispensing cartridge 151 and the dispensing port 1322. In some examples, when there are multiple dispensing ports 1322, the catheter may collect medications released from multiple dispensing ports 1322 into the dispensing cartridge 151.
[0114] In some examples, there can be multiple catheters. Multiple catheters can be connected to multiple drug outlets 1322. This reduces the possibility of catheter blockage.
[0115] As described above, the drug reservoir 12 can move relative to the sieve plate 14. In some examples, the drug delivery system 1 may include a drive mechanism. In some examples, the drive mechanism may be configured to drive the drug reservoir 12. The drive mechanism can drive the drug reservoir 12 to move relative to the sieve plate 14. In this case, since the drug in the drug reservoir 12 may not be able to spontaneously pass through the sieve holes 141 (e.g., the drug moves under its own gravity), by driving the drug reservoir 12 to move relative to the sieve plate 14, the drug reservoir 12 can exert an action on the drug to make the drug move, thereby facilitating the passage of the drug through the sieve holes 141. In addition, by driving the drug reservoir 12 and thus driving the drug in the drug reservoir 12, the drug can be made to move relative to the sieve holes 141, reducing the possibility of the drug clogging the sieve holes 141. Specifically, as the position of the sieve hole 141 relative to the drug changes, the movement trend of multiple drugs changes. Some drugs have a stronger tendency to pass through the sieve hole 141, while the tendency of other drugs to pass through the sieve hole 141 is weakened. This makes multiple drugs no longer tend to pass through the sieve hole 141 at the same time, thereby reducing the possibility of clogging the sieve hole 141.
[0116] In other examples, the drive mechanism may also drive the sieve plate 14 to move relative to the drug storage section 12.
[0117] In some examples, the drive mechanism can drive the drug reservoir 12 to reciprocate. The trajectory of the reciprocating motion of the drug reservoir 12 can be a straight line or a curve. In this case, it can help the drug reservoir 12 to act on the drug located at different positions, thereby further reducing the possibility that the drug cannot pass through the sieve hole 141.
[0118] Figure 4A This is a schematic diagram illustrating the principle of the first embodiment of the relative movement between the medicine storage section 12 and the sieve plate 14 involved in this utility model example. Figure 4B This is a schematic diagram illustrating the principle of the second embodiment of the relative movement between the medicine storage section 12 and the sieve plate 14 according to an example of this utility model. It should be noted that, in order to more clearly illustrate the relative movement between the medicine storage section 12 and the sieve plate 14, in... Figure 4A and Figure 4B Some components that might affect observation have been omitted, but this should not be interpreted as the drug delivery system 1 including only the components shown in the figure.
[0119] See in some examples Figure 4AThe shape of the drug inlet 121 can be circular. The shape of the sieve hole 141 can also be circular. In some examples, the drive mechanism can drive the drug reservoir 12 to perform a circular motion (or rotational motion) along the D2 direction (or the direction opposite to D2). In some examples, the drive mechanism can drive the drug reservoir 12 to perform a circular motion in a manner that is tangent to the sieve hole 141. In this case, by performing a circular motion in a manner that is tangent to the sieve hole 141, it is possible to help the drug reservoir 12 apply force to the drug at various positions and bring the drug closer to the sieve hole 141.
[0120] In some examples, when the drug reservoir 12 moves along the D2 direction, the drug reservoir 12 can move in a circular motion. In some examples, the drive mechanism may include a motor. In this case, when the drug reservoir 12 moves in a circular motion, the motor of the drive mechanism can be directly connected to the drug reservoir 12, which facilitates the drive mechanism to drive the drug reservoir 12 to move in a circular motion.
[0121] See in some examples Figure 4B The drug inlet 121 can be oblong. The sieve hole 141 can be circular. In some examples, the size of the oblong hole can match the size of the sieve hole 141. Matching can mean that the width of the straight section of the oblong hole and the diameter of the circular section are equal to the diameter of the sieve hole 141. In some examples, the drive mechanism can drive the drug storage section 12 to move linearly along the D3 direction (or the opposite direction to D3). This facilitates the drug storage section 12 to apply force to the drug at various positions and bring the drug closer to the sieve hole 141.
[0122] In some examples, when the drug reservoir 12 moves along the D3 direction, the drug reservoir 12 can move linearly. In some examples, the drive mechanism may include a motor and a crank-connecting rod mechanism. In this case, when the drug reservoir 12 moves linearly, the motor of the drive mechanism can be connected to the drug reservoir 12 through the crank-connecting rod mechanism, so that the torque generated by the motor is converted into a driving force in the linear direction, thereby facilitating the drive mechanism to drive the drug reservoir 12 to move linearly.
[0123] See in some examples Figure 2B The drug delivery system 1 may include a sensor 16. In some examples, the sensor 16 may be configured to detect whether a drug has passed by.
[0124] In some examples, sensor 16 can be located at the drug inlet 1321 or the drug outlet 1322. This facilitates the calculation of the amount of drug administered by the drug delivery system 1.
[0125] See in some examples Figure 2BThe sensor 16 can be installed at the inlet 1321 and the outlet 1322. In this case, by sensing the medicine passing through the inlet 1321 and the outlet 1322 by the sensor 16, the amount of medicine in the transport mechanism 13 can be easily obtained.
[0126] In some examples, sensor 16 can be a counting sensor. For example, sensor 16 can be a photoelectric sensor.
[0127] In this invention, the medicine in the storage section 12 enters the receiving tank 1311 through the supply port 121 and the inlet 1321 of the housing 132. The rotating part 131 rotates the receiving tank 1311 from a first position to a second position, thereby releasing the medicine from the receiving tank 1311 through the outlet 1322. The transport mechanism 13 transports the medicine by rotating the rotating part 131, which helps to make the structure of the transport mechanism 13 more compact compared to translation. In addition, by setting the sieve plate 14 between the storage section 12 and the transport mechanism 13, the sieve plate 14 can easily restrict the medicine supplied by the storage section 12 to the transport mechanism 13; by matching the size of the sieve holes 141 with the size of the medicine, the movement of the medicine can be restricted, so that the medicine is received at the expected position of the transport mechanism 13, reducing the impact of the medicine on the normal operation of the transport mechanism 13, thereby improving the reliability of the drug delivery system 1.
