Description

Technical Field

[0001] This utility model relates to the field of biomedical engineering industry, specifically to a drug dispensing system. Background Technology

[0002] A smart medicine dispenser is a home health device that integrates drug storage, timed reminders, and intelligent medication dispensing. It not only safely stores various medications but also helps users accurately manage medication times through intelligent methods, effectively solving problems such as missed doses and incorrect doses.

[0003] A smart pharmacy typically includes a medicine storage box for storing medicines, a medicine dispensing box for users to retrieve medicines, and a medicine retrieval mechanism. Based on the quantity, type, and time of medication set by the user in advance, the mechanism is controlled to enter the medicine storage box to retrieve medicines and move them to the medicine dispensing box, thereby providing the user with the predetermined quantity and type of medicines at regular intervals.

[0004] However, during the process of the medicine-collecting mechanism entering the medicine storage box, it may exert unintended effects on the medicine, resulting in damage to the medicine (for example, the medicine-collecting mechanism crushing the medicine by going too deep into the medicine storage box). Summary of the Invention

[0005] This invention is proposed in view of the above-mentioned state of the prior art, and its purpose is to provide a dispensing system that can help protect pharmaceuticals.

[0006] Therefore, this utility model provides a dispensing system, including a drug storage section for storing drugs, a drug delivery section for transporting drugs, a detection module, and a control module. The delivery section includes a drug picking mechanism and a negative pressure mechanism. The drug picking mechanism includes a housing and a contact part movably connected to the housing for picking up drugs. The negative pressure mechanism is connected to the contact part and provides negative pressure to the contact part for picking up drugs. The detection module includes a first detection part disposed on the housing and a second detection part disposed on the contact part. During the process of the drug picking mechanism picking up drugs, the first detection part and the second detection part cooperate to generate an electrical signal through the relative movement of the contact part and the housing. The control module receives the electrical signal to control the drug picking mechanism to pick up drugs through the negative pressure provided by the negative pressure mechanism and to control the drug picking mechanism to move the drugs from the drug storage section to the target position.

[0007] In this invention, a negative pressure mechanism provides negative pressure to the contact part, facilitating the pickup mechanism's retrieval of medicine from the storage compartment. The control module then controls the pickup mechanism to move the medicine from the storage compartment to the target location, making it convenient for the user to access the medicine. Since the first detection part is located in the housing and the second detection part is located in the contact part, when the pickup mechanism contacts the medicine, the relative movement between the contact part and the housing causes relative movement between the first and second detection parts. This generates an electrical signal, which the control module receives and controls to pick up and move the medicine. By detecting the relative movement between the contact part and the housing, the control module can determine whether the pickup mechanism is in contact with the medicine, allowing it to adjust the mechanism's movement in a timely manner to prevent damage to the medicine.

[0008] Furthermore, in the dispensing system of this invention, optionally, a dispensing unit is included that matches the target position. When the dispensing mechanism moves to the target position, the dispensing mechanism releases the medication. This helps to ensure that the medication accurately enters the dispensing unit.

[0009] In addition, in the dispensing system of this utility model, optionally, the control module receives the electrical signal to control the negative pressure mechanism to provide negative pressure to the contact part. When the drug-collecting mechanism moves to the target position, the control module controls the negative pressure mechanism to stop generating negative pressure so that the drug-collecting mechanism releases the drug. In this case, by stopping the negative pressure and allowing the drug to fall freely, the drug can be easily released.

[0010] Furthermore, in the dispensing system of this invention, optionally, the detection module is a photoelectric sensor. When the contact part moves relative to the housing, the second detection part blocks the signal emitted by the first detection part, causing the detection module to generate the electrical signal. This facilitates the detection of the relative movement between the contact part and the housing.

[0011] Furthermore, in the dispensing system of this invention, optionally, at least a portion of the contact part is made of an elastic material. In this case, it helps the contact part deform to conform to the drug upon contact, thereby enabling the drug-pickup mechanism to pick up the drug more stably. Additionally, it reduces the force exerted by the contact part on the drug, thus protecting the drug.

[0012] Furthermore, in the dispensing system of this invention, the drug storage section may optionally include multiple drug storage boxes. This facilitates the storage of various different drugs.

[0013] Furthermore, in the dispensing system of this invention, optionally, the contact portion has a suction hole, the size of which is no larger than the size of the medicine. This helps to prevent the medicine from being drawn into the interior of the contact portion under negative pressure.

[0014] Additionally, the dispensing system of this utility model may optionally include a drive module. The drive module includes a first drive arm and a second drive arm movably connected to the first drive arm. The first drive arm is connected to the drug-picking mechanism. The first drive arm and the second drive arm are positioned relatively close together to bring the drug-picking mechanism closer to the drug storage section to pick up the drug, and relatively far apart to move the drug-picking mechanism away from the drug storage section. This facilitates the drug-picking mechanism in picking up and moving the drug.

[0015] Furthermore, in the dispensing system of this invention, optionally, the first drive arm and the second drive arm are connected by any one of a spring, a hinge, and a ball joint. This facilitates relative movement between the first and second drive arms.

[0016] Furthermore, in the dispensing system of this invention, optionally, the end of the first drive arm closest to the second drive arm is made of a magnetic material, and the end of the second drive arm closest to the first drive arm is also made of a magnetic material. This allows for easy control of the relative proximity and distance between the first and second drive arms.

[0017] According to this invention, a dispensing system that helps protect pharmaceuticals can be provided. Attached Figure Description

[0031] The drug dispensing system described in this invention helps protect medicines, reduces the possibility of damage, and thus enables more stable drug delivery. In some examples, the drug dispensing system uses a detection module to detect whether the drug pickup mechanism is in contact with the medicine, and then uses a control module to control the movement of the drug pickup mechanism to prevent damage to the medicine.

[0032] In some examples, the dispensing system involved in this utility model may also be referred to as a dispensing system, a drug preparation system, a drug distribution system, or a drug storage area, etc. The detection module involved in this utility model may also be referred to as a detection unit, a detector, a displacement detector, or a sensor, etc. The control module involved in this utility model may also be referred to as a control unit, a controller, a processing unit, or a processor, etc.

[0033] The following detailed description of the drug dispensing system involved in this utility model example is provided in conjunction with the accompanying drawings.

[0034] Figure 1 This is a diagram illustrating an application scenario of the dispensing system 1 involved in this utility model example.

[0035] In some examples, the dispensing system 1 can be configured to dispense (or prepare) medications. Dispensing medications can refer to preparing medications according to the user's requirements for the type and quantity of medication. In some examples, the dispensing system 1 can provide the user with pre-prepared medications.

[0036] In some examples, the dispensing system 1 can be configured to receive instructions. These instructions may contain information about the type and quantity of medication. Upon receiving the instructions, the dispensing system 1 can then dispense the medication. In some examples, the instructions may be sent by a user.

[0037] In some examples, instructions can be sent via external device 2 (see...) Figure 1 External device 2 can be operated by the user.

[0038] See in some examples Figure 1 The medication dispensing system 1 may include a display screen 11. Users can also send instructions to the medication dispensing system 1 through the display screen 11.

[0039] In some examples, when a user takes a medicine, the display screen 11 can show the type and quantity of medicine in the dispensing section 13 (described in detail later).

[0040] In some examples, the instructions may also include the time the user needs to take the medication (i.e., the medication time). The medication dispensing system 1 can prepare the medication before the medication time.

[0041] In some examples, the medication dispensing system 1 can remind the user to take their medication before or at the scheduled time. For example, the reminder could be sent to an external device 2 to alert the user and / or accompanied by an audible alert.

[0042] 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.

[0043] Figure 2 This is a schematic diagram showing the structure of the dispensing system 1 involved in this utility model example.

[0044] In some examples, the dispensing system 1 may include a drug storage unit 12 (see [reference]). Figure 2 The medicine storage section 12 can be used to store medicines. In some examples, the user can add medicines to the medicine storage section 12 before the medicine is dispensed by the dispensing system 1.

[0045] In some examples, the drug storage section 12 may include multiple drug storage boxes 121. This facilitates the storage of a variety of different drugs.

[0046] See in some examples Figure 2 The medicine storage box 121 can be tapered from top to bottom. For example, the area of ​​the opening of the medicine storage box 121 can be larger than the area of ​​the bottom of the medicine storage box 121. This helps to concentrate the medicine in the medicine storage box 121, making it easier to pick up. For example, the medicine storage box 121 can be frustum-shaped.

[0047] In other examples, the medicine storage box 121 may also be cylindrical and / or square in shape.

[0048] See in some examples Figure 1 or Figure 2 The medication dispensing system 1 may include a medication dispensing unit 13. The medication dispensing unit 13 may be configured to provide medications to users. That is, users can obtain medications through the medication dispensing unit 13.

[0049] In some examples, when a user takes a medicine, the dispensing system 1 can display the type and quantity of medicine in the dispensing section 13 on the display screen 11.

[0050] See in some examples Figure 2 The dispensing system 1 may include a delivery unit 14. The delivery unit 14 can be used to deliver medicines.

[0051] In some examples, the transport unit 14 can transport medicines from the medicine storage unit 12 to the medicine dispensing unit 13. In some examples, the transport unit 14 can also transport medicines from the medicine dispensing unit 13 to the medicine storage unit 12.

[0052] In some examples, the transport unit 14 may include a medicine collection mechanism 141 (see...) Figure 2 In some examples, the medicine-collecting mechanism 141 can be configured to collect medicines. In some examples, the medicine-collecting mechanism 141 can collect medicines from the medicine storage section 12.

[0053] In some examples, the medicine-collecting mechanism 141 can access the medicine storage section 12. This facilitates the collection of medicines.

[0054] Figure 3 It shows Figure 2 A cross-sectional view of the drug-collecting mechanism 141 along XX.

[0055] See in some examples Figure 3 The drug-collecting mechanism 141 may include a contact part 1411. The contact part 1411 can be used to collect drugs. The contact part 1411 can collect drugs in a manner that involves contact with the drugs. The drug-collecting mechanism 141 can contact the drugs through the contact part 1411.

[0056] In some examples, at least a portion of the contact portion 1411 (e.g., the portion that contacts the drug) may be made of an elastic material. In this case, it is possible for the contact portion 1411 to deform upon contact with the drug to conform to the drug, thereby enabling the drug-picking mechanism 141 to pick up the drug more stably. In addition, it is possible to reduce the force exerted by the contact portion 1411 on the drug, thereby protecting the drug.

[0057] In some examples, the size of the portion of the contact part 1411 that can access the medicine may not be larger than the size of the medicine. This allows the medicine-picking mechanism 141 to pick up only a single medicine in a single pickup, thereby helping the dispensing system 1 to accurately provide the user with the required quantity of medicine.

[0058] In some examples, the contact portion 1411 may have a suction orifice. The size of the suction orifice may not be larger than the size of the drug. Specifically, the size of the suction orifice may not be larger than the size of a single drug. This helps to prevent the drug from being drawn into the interior of the contact portion 1411 under negative pressure.

[0059] In some examples, the suction hole may be located on the portion of the contact portion 1411 that is accessible to the medicine.

[0060] In some examples, there can be multiple suction holes. In this case, dispersing the negative pressure acting on the drug helps prevent damage to the drug due to stress concentration.

[0061] In some examples, when there are multiple suction holes, the total size of the multiple suction holes may not exceed the size of the medicine.

[0062] In other examples, the number of suction holes can also be one.

[0063] See in some examples Figure 2 or Figure 3 The drug-collecting mechanism 141 may include a housing 1412. The contact portion 1411 may be connected to the housing 1412.

[0064] In some examples, the contact portion 1411 may be movably connected to the housing 1412. During the process of the drug-picking mechanism 141 picking up the drug, the contact portion 1411 and the housing 1412 may move relative to each other. Specifically, before the drug-picking mechanism 141 picks up the drug, the contact portion 1411 and the housing 1412 move synchronously and remain relatively stationary; when the drug-picking mechanism 141 moves to contact the drug, the contact portion 1411 comes into contact with the drug and remains relatively stationary, while the housing 1412 continues to move a certain distance. Since the contact portion 1411 and the housing 1412 are movably connected, relative movement occurs between the contact portion 1411 and the housing 1412 at this time.

[0065] In some examples, the drug-collecting mechanism 141 releases the drug when it moves to the target position. This helps to ensure that the drug is accurately delivered to the drug dispensing section 13.

[0066] In some examples, the target location can be matched with the dispensing unit 13. In some examples, the dispensing unit 13 can be located directly below the target location. In this case, the medicine can enter the dispensing unit 13 by its own gravity, which simplifies the movement path of the dispensing mechanism 141.

[0067] In some examples, the dispensing unit 13 may also be located at the target location.

[0068] See in some examples Figure 2 The transport unit 14 may include a negative pressure mechanism 142. The negative pressure mechanism 142 may be configured to generate negative pressure. For example, the negative pressure mechanism 142 may be a vacuum pump, a negative pressure pump, or an adsorption pump.

[0069] In some examples, the negative pressure mechanism 142 can provide negative pressure to the drug-collecting mechanism 141. In some examples, the negative pressure mechanism 142 can provide negative pressure to the contact portion 1411. The negative pressure can be used to collect the drug. In other words, the drug-collecting mechanism 141 can collect the drug using the negative pressure provided by the negative pressure mechanism 142. In this case, by providing negative pressure to the contact portion 1411 through the negative pressure mechanism 142, it is convenient for the drug-collecting mechanism 141 to collect the drug from the drug storage section 12.

[0070] In some examples, the negative pressure mechanism 142 can be connected to the drug pickup mechanism 141 (see [reference]). Figure 2 In some examples, the negative pressure mechanism 142 may be connected to the contact portion 1411 (see [link]). Figure 3 Therefore, it is convenient for the negative pressure mechanism 142 to provide negative pressure to the contact part 1411.

[0071] See in some examples Figure 2 The negative pressure mechanism 142 may include a negative pressure generating device 1421 and a pipe 1422.

[0072] In some examples, the negative pressure generating device 1421 can generate negative pressure. A conduit 1422 can connect the negative pressure generating device 1421 and the drug pickup mechanism 141 (e.g., contact part 1411). The negative pressure generating device 1421 can supply the generated negative pressure to the contact part 1411 via the conduit 1422.

[0073] In some examples, a filter may be installed in the conduit 1422. This helps to prevent damage to the negative pressure mechanism 142 from accidentally inhaled medication.

[0074] See in some examples Figure 3 The dispensing system 1 may include a detection module 15. In some examples, the detection module 15 may be configured to detect the relative movement (or relative position) between the contact portion 1411 and the housing 1412.

[0075] See in some examples Figure 3 The detection module 15 may include a first detection unit 151. The first detection unit 151 may be disposed on the housing 1412. The detection module 15 may also include a second detection unit 152. The second detection unit 152 may be disposed on the contact portion 1411. Thus, the first detection unit 151 and the second detection unit 152 can be moved with the housing 1412 and the contact portion 1411, respectively.

[0076] In some examples, the first detection unit 151 and the second detection unit 152 can move relative to each other.

[0077] In some examples, the first detection unit 151 can be used to detect the movement of the housing 1412. The second detection unit 152 can be used to detect the movement of the contact portion 1411. The relative movement between the housing 1412 and the contact portion 1411 can be detected by the relative movement of the first detection unit 151 and the second detection unit 152.

[0078] In some examples, the detection module 15 may also be configured to provide feedback on the relative movement of the contact portion 1411 and the housing 1412 via the relative movement of the first detection portion 151 and the second detection portion 152.

[0079] In some examples, during the process of picking up medicine by the medicine-picking mechanism 141, the first detection unit 151 and the second detection unit 152 can cooperate through the relative movement of the housing 1412 and the contact unit 1411.

[0080] In some examples, the detection module 15 can generate an electrical signal. This electrical signal can be used to control the drug-collecting mechanism 141. In some examples, the first detection unit 151 and the second detection unit 152 can cooperate to generate an electrical signal.

[0081] In some examples, the dispensing system 1 may include a control module 16 (see...) Figure 2In some examples, control module 16 can receive electrical signals. In some examples, control module 16 can be configured to control the delivery unit 14 to deliver medicines.

[0082] In some examples, the control module 16 can be an MCU (Microcontroller Unit).

[0083] In some examples, the control module 16 can also be a PLC (Programmable Logic Controller), an embedded processor, a relay, or a motor driver, etc.

[0084] In some examples, control module 16 may be configured to control drug-collecting mechanism 141. In some examples, control module 16 may receive electrical signals to control drug-collecting mechanism 141.

[0085] See in some examples Figure 2 The control module 16 can also be connected to the drug-collecting mechanism 141. This allows it to easily receive electrical signals and control the drug-collecting mechanism 141.

[0086] In some examples, control module 16 can control the drug-picking mechanism 141 to pick up drugs.

[0087] In some examples, the drug-collecting mechanism 141 can also be configured to move the drug. In some examples, the control module 16 can control the drug-collecting mechanism 141 to move the drug. Specifically, the control module 16 can control the drug-collecting mechanism 141 to move the drug from the drug storage section 12 to the target location.

[0088] In some examples, the control module 16 can control the drug-collecting mechanism 141 to move the medicine from the drug storage section 12 to the target location. In this case, controlling the drug-collecting mechanism 141 to move the medicine from the drug storage section 12 to the target location via the control module 16 makes it easier for the user to retrieve the medicine.

[0089] As described above, the first detection unit 151 and the second detection unit 152 can be respectively disposed in the housing 1412 and the contact unit 1411. The control module 16 can receive electrical signals to control the drug picking mechanism 141 to pick up the drug and move the drug from the drug storage unit 12 to the target position. In this configuration, since the first detection unit 151 is located on the housing 1412 and the second detection unit 152 is located on the contact unit 1411, when the drug-picking mechanism 141 contacts the drug, the relative movement between the contact unit 1411 and the housing 1412 causes the relative movement between the first detection unit 151 and the second detection unit 152. This causes the first detection unit 151 and the second detection unit 152 to generate an electrical signal. After receiving the electrical signal, the control module 16 can control the drug-picking mechanism 141 to pick up and move the drug. Thus, by detecting whether the contact unit 141 and the housing 1412 are moving relative to each other, it can be determined whether the drug-picking mechanism 141 is in contact with the drug. This helps the control module 16 to adjust the movement state of the drug-picking mechanism 141 in a timely manner to avoid the drug-picking mechanism 141 damaging the drug (for example, the drug-picking mechanism 141 continues to move toward the drug after contacting it, causing the drug to be damaged due to excessive compression by the drug-picking mechanism 141).

[0090] In some examples, the movement state of the drug-collecting mechanism 141 can refer to the drug-collecting mechanism 141 moving closer to or further away from the drug storage section 12. For example, when the drug-collecting mechanism 141 moves closer to the drug storage section 12, it can move vertically closer to the drug storage section 12. As another example, when the drug-collecting mechanism 141 moves away from the drug storage section 12, it can move vertically away from the drug storage section 12 or horizontally away from the drug storage section 12.

[0091] In some examples, control module 16 may be configured to control negative pressure mechanism 142. In some examples, control module 16 may receive electrical signals to control negative pressure mechanism 142.

[0092] See in some examples Figure 2 The control module 16 can be connected to the negative pressure mechanism 142. This allows the control module 16 to easily control the negative pressure mechanism 142.

[0093] In some examples, the control module 16 can control the negative pressure mechanism 142 to provide negative pressure to the contact portion 1411.

[0094] In some examples, the control module 16 can also control the negative pressure mechanism 142 to stop generating negative pressure. When the negative pressure mechanism 142 stops generating negative pressure, the drug pickup mechanism 141 can release the drug. In this case, stopping the negative pressure to allow the drug to fall freely facilitates the release of the drug.

[0095] In some examples, when the drug-collecting mechanism 141 moves to the target position, the control module 16 can control the negative pressure mechanism 142 to stop generating negative pressure so that the drug-collecting mechanism 141 releases the drug.

[0096] In other examples, the negative pressure mechanism 142 may also receive electrical signals. Specifically, the negative pressure mechanism 142 can provide or stop generating negative pressure by directly receiving electrical signals.

[0097] In some examples, the detection module 15 can be a sensor. In some examples, the detection module 15 can be a photoelectric sensor. In some examples, the first detection unit 151 can transmit a signal.

[0098] In other examples, the detection module 15 may also be a capacitive sensor or a switch-type sensor (e.g., a Hall sensor).

[0099] Figure 4 This is a schematic diagram showing the relative movement of the contact portion 1411 and the housing 1412 involved in this utility model example.

[0100] See in some examples Figure 4 When the contact portion 1411 moves relative to the housing 1412, the second detection portion 152 can block the signal emitted by the first detection portion 151 to generate an electrical signal in the detection module 15. This facilitates the detection of the relative movement between the contact portion 1411 and the housing 1412.

[0101] In some examples, the first detection unit 151 may include a transmitter for transmitting a signal and a receiver for receiving the signal transmitted by the transmitter. When the contact 1411 moves relative to the housing 1412, that is, when the first detection unit 151 moves relative to the second detection unit 152, the second detection unit 152 may move between the transmitter and the receiver to block the signal transmitted by the transmitter, thereby preventing the receiver from receiving the signal transmitted by the transmitter, thus causing the detection module 15 to generate an electrical signal.

[0102] In other examples, before the contact portion 1411 moves relative to the housing 1412, the second detection portion 152 may be positioned between the transmitter and receiver to isolate the signal emitted by the transmitter. In this case, when the first detection portion 151 and the second detection portion 152 move relative to each other, the second detection portion 152 may move away from the transmitter and receiver so that the receiver can receive the signal emitted by the transmitter, thereby enabling the detection module 15 to generate an electrical signal.

[0103] Figure 5 This is a schematic diagram illustrating another embodiment of the detection module 15 involved in this utility model example.

[0104] See in some examples Figure 5 The detection module 15 can also be a capacitor. In some examples, the first detection unit 151 and the second detection unit 152 can be plates.

[0105] In some examples, when the contact portion 1411 moves relative to the housing 1412, the first detection portion 151 and the second detection portion 152 also move relative to each other, and the two plates can move closer or further apart to change the capacitance. Therefore, it is convenient to detect the relative movement of the contact portion 1411 and the housing 1412 by means of changes in capacitance.

[0106] Figure 6 This is a schematic diagram illustrating another embodiment of the detection module 15 involved in this utility model example.

[0107] See in some examples Figure 6 The detection module 15 can also be a switch structure.

[0108] In some examples, the first detection unit 151 and the second detection unit 152 may be made of a conductive material. When the contact portion 1411 moves relative to the housing 1412, the first detection unit 151 and the second detection unit 152 also move relative to each other, and the first detection unit 151 and the second detection unit 152 can change from being conductive to being disconnected (or from being disconnected to being conductive). Therefore, it is convenient to detect the relative movement of the contact portion 1411 and the housing 1412 by the on / off state of the first detection unit 151 and the second detection unit 152.

[0109] See in some examples Figure 2 The dispensing system 1 may include a drive module 17. The drive module 17 may be configured to drive the drug pickup mechanism 141.

[0110] In some examples, the drive module 17 can be a servo robotic arm.

[0111] In some examples, drive module 17 may include a drive source configured to provide driving force. For example, the drive source may be a drive motor.

[0112] As described above, the control module 16 can control the drug-picking mechanism 141 to move the drug from the drug storage section 12 to the target location. In some examples, the control module 16 can control the drive module 17 to drive the drug-picking mechanism 141 to move the drug from the drug storage section 12 to the target location.

[0113] In other examples, the drive module 17 can receive electrical signals. Specifically, the drive module 17 can drive the drug-collecting mechanism 141 by directly receiving electrical signals.

[0114] Figure 7 It shows Figure 2 The drive module 17 in the middle is shown in a cross-sectional view along the YY direction.

[0115] See in some examples Figure 7 The drive module 17 may include a first drive arm 171. The first drive arm 171 may be connected to the drug-picking mechanism 141. This facilitates the drive module 17 in driving the drug-picking mechanism 141.

[0116] In some examples, the first drive arm 171 can drive the drug-picking mechanism 141 to move vertically. This helps to control the drug-picking mechanism 141 to pick up the drug.

[0117] In other examples, the first drive arm 171 may also drive the drug-collecting mechanism 141 to move on a horizontal plane.

[0118] See in some examples Figure 7 The drive module 17 may include a second drive arm 172.

[0119] In some examples, the second drive arm 172 can drive the drug-collecting mechanism 141 to move on a horizontal plane. This helps to control the movement of the drug-collecting mechanism 141 between the drug storage section 12 and the drug dispensing section 13, as well as the movement of the drug-collecting mechanism 141 between multiple drug storage boxes 121.

[0120] In other examples, the second drive arm 172 may also drive the drug-collecting mechanism 141 to move in the vertical direction.

[0121] In some examples, the first drive arm 171 and the second drive arm 172 can also rotate about their own axes.

[0122] In some examples, the second drive arm 172 may be movably connected to the first drive arm 171. This allows the drive module 17 to drive the drug-collecting mechanism 141 more flexibly.

[0123] In some examples, the first drive arm 171 and the second drive arm 172 can be connected by a spring (see...). Figure 7 The connection can be any of the following: a hinge or a ball joint. This facilitates relative movement between the first drive arm 171 and the second drive arm 172.

[0124] In some examples, the first drive arm 171 can be positioned relatively close to the second drive arm 172 to bring the drug-collecting mechanism 141 close to the drug storage section 12 to collect the drug. This facilitates the drug-collecting mechanism 141 in collecting the drug.

[0125] In some examples, the first drive arm 171 can be positioned relatively far from the second drive arm 172 to move the drug-collecting mechanism 141 away from the drug storage section 12. This facilitates the movement of the drug-collecting mechanism 141.

[0126] See in some examples Figure 7 The first drive arm 171 and the second drive arm 172 can be arranged vertically. This allows the first drive arm 171 and the second drive arm 172 to move the drug-picking mechanism 141 closer to (or further away from) the drug storage section 12 in a relatively close (or far away) manner.

[0127] In some examples, the end of the first drive arm 171 closest to the second drive arm 172 (which may be simply referred to as the first end) may be made of a magnetic material. The end of the second drive arm 172 closest to the first drive arm 171 (which may be simply referred to as the second end) may also be made of a magnetic material. This allows for easy control of the first drive arm 171 and the second drive arm 172 moving closer or further apart.

[0128] As described above, the first drive arm 171 and the second drive arm 172 can be connected by a spring. When the first end and the second end are engaged, they can approach each other, the spring can be compressed, and the first drive arm 171 can drive the drug-collecting mechanism 141 to move vertically closer to the drug storage section 12. When the first end and the second end are no longer engaged, the spring can return to its original state, and the first end and the second end can move away from each other under the action of the spring. The first drive arm 171 can drive the drug-collecting mechanism 141 to move vertically away from the drug storage section 12.

[0129] In this invention, the negative pressure mechanism 142 provides negative pressure to the contact part 1411, which facilitates the drug picking mechanism 141 to pick up the medicine from the medicine storage part 12. The control module 16 controls the drug picking mechanism 141 to move the medicine from the medicine storage part 12 to the target position, thereby facilitating the user to take the medicine. Since the first detection unit 151 is disposed on the housing 1412 and the second detection unit 152 is disposed on the contact part 1411, when the drug-collecting mechanism 141 contacts the drug, the relative movement of the contact part 1411 and the housing 1412 causes the relative movement of the first detection unit 151 and the second detection unit 152, thereby generating an electrical signal in cooperation between the first detection unit 151 and the second detection unit 152. After receiving the electrical signal, the control module 16 can control the drug-collecting mechanism 141 to pick up and move the drug. Thus, by detecting whether the contact part 141 and the housing 1412 are in relative movement, it can be determined whether the drug-collecting mechanism 141 is in contact with the drug, thereby helping the control module 16 to adjust the movement state of the drug-collecting mechanism 141 in a timely manner to avoid damage to the drug by the drug-collecting mechanism 141. In summary, according to this utility model, a drug dispensing system 1 that helps protect drugs can be provided.

Those skilled in the art can make modifications and variations to the present invention as needed without departing from the essential spirit and scope of the present invention, and all such modifications and variations fall within the scope of the present invention.
