BACKGROUND

Improving medical adherence and compliance is an area of interest for medical practitioners and patients alike. Traditional solutions, like the various types of pill boxes and smart caps, may fail to address the root causes of medical non-adherence completely and effectively.
For instance, in an attempt to improve patient compliance, some systems may include timer-like functions or smart phone applications to remind patients when to take specific medications. However, these solutions may not effectively monitor whether the right dosage has been taken. For instance, tracking each time a bottle has been opened may not account for, for instance, how many pills are taken at a time. Furthermore, pharmacists or clinicians may not properly preprogram a patient's drug routine into a solution (e.g., in the form of programming a traditional RF tag, as an example). Such can limit accessibility of solutions to a minority of the population and may prevent proper usage for many patients and caregivers. For people taking multiple medications, there is always a possibility of mixing-up pills between reminders. For instance, a physical reminder device initially set-up to remind and track pill A may not track a second pill B if misplaced in a bottle.
Pre-sorting pill devices (e.g., pill boxes) may help manage complex medicine regimens. For instance, a user may actively prepare the medications to be taken over a coming week or even a month. However, these solutions may include significant cognitive effort, and pre-sorting the medications can be both cumbersome for the user, and prone to errors in sorting the medications correctly (i.e., the user may not correctly sort out the correct medication, in the right dosage, for the right time, all the time). Other solutions may fail to effectively remind or notify the patient when to take a certain dosage of medication.
There have also been numerous attempts to develop automatic dispensing systems. However, previous medicine-dispensing devices may fail to reliably dispense medications when needed.
Therefore, a need in the field exists for a solution that can not only dispense and remind patients when to take specific medications, but also track that the correct dosages have been taken by the patient at the correct time and ensure that the right medication is taken. A need also exists for a dispensing system to successfully determine whether there has been a mistake in the dispensing process without intervention from the patient; this need exists to increase operational reliability to extremely high levels. A further need exists for a reminder system notifying patients to bring their medications along when they leave their homes. A need also exists for a solution for the above, while still remaining accessible to an average patient (i.e., having only minimal changes to the patient's lifestyle) since some solutions rely on pharmacists or clinicians to program the device, which can limit accessibility of the solution to limited populations with access to the technology.

The present disclosure relates to devices supporting medication compliance. More specifically, this may include an automatic medicine dispensing system with a portable monitoring device for notifying users when to take their medications and for logging when medications have been taken automatically through a programmable patient apparatus.
The present disclosure includes a system and method and a set of devices which, when used together, assist people in managing either their medications or the medications of somebody they are taking care of. By using the disclosed medicine dispensing method the disclosed device dispenses medications automatically and more accurately than other available dispensing devices, notifying patients when to take specific medications and track the exact dosage taken by a patient at a given time, all while ensuring the notification is for the originally intended medication. For example, by using the prescription data input method of this disclosure, the systems herein may be readily programmable by individual patients. Also, the use of a location tracking method creates a way to remind patients when medications may have been forgotten at home.
Further areas of applicability will become apparent from the description provided herein. It should be understood that the description and specific examples are intended for purposes of illustration only and are not intended to limit the scope of present disclosure.
The following description is merely exemplary in nature and is not intended to limit the present disclosure, application, or uses. It should be understood that throughout the drawings, corresponding reference numerals indicate corresponding parts and features. The terms “device,” “unit” and “module” may be used interchangeably. The terms “robot” means a complete robot system and/or different sub-system of the same robot or any type of machines. The term “medicine” means any form of medicine that may include a pill or capsule.
The systems and methods herein may include one or more of a station door or a medicine container loading station door (MCLSD), a storage container or medicine storage container (MSC), a loading station or medicine container loading station (MCLS), a reminder device or medicine reminder unit (MRU), a travel device or medicine travel unit (MTRU), a container transfer device or medicine container transfer unit (MCTU), a storage nest or medicine container storage nest (MCSN), a loading point or medicine container loading point (MCLP), a discharge point or medicine discharge point (MDP), a medicine transfer device or medicine transfer unit (MTU), a medicine container or dispensed medicine container (DMC), a transfer container or medicine transfer container (MTC), an identification device or medicine container identification unit (MCIU), a standard container or original medicine container without cap (OMC), a detecting device or weight detecting device (WDD), an arm tool or end of arm tool (EOAT), an alert device or travel alert unit (TAU), and a checking station or weight checking station (WCS).
Referring now to the figures, FIG. 1 illustrates an exemplary system 100 that is configured to receive, store, monitor, display and transfer medication information. The system 100 may be configured for monitoring the dosage and usage of prescription medication. The system 100 may also be configured to dispense the prescription medication according to required dosages. The system 100 may include a dispensing device 102 and at least one of assemblies 140, 150 a-d, 160, and 170. Generally, assembly 140 may be a travel alert device, assemblies 150 a-d may be medicine travel devices, and assemblies 160 and 170 may be medicine reminder devices, for example, as described in detail in U.S. patent application Ser. Nos. 15/613,675 and 15/613,852. The dispensing device 102 may include a processor 106, a memory 108 with a program 110 stored thereon, a display 112, at least one input/output (I/O) device 114, and a communication device 116, as described in more detail with respect to FIG. 5.
Medication information may include any information associated with medication or medicine. Medication information may be associated with or include a prescription (e.g., patient name, prescriber name, strength, dosage, quantity, expiration, use directions, or drug or diet interactions), a container type (e.g., shape, size, or color), patient information (e.g., name or history), or a combination thereof. Medication information may include other information associated with a patient or medication.
Prescription information may include medication information associated with a patient or as prescribed or defined by a user such as medical professional or a patient. Container information may include medication information associated with a medication container or according to an identifier on a medication container. As such, the prescription information and container information may or may not match depending on whether the prescription was properly and accurately fulfilled or not. The container information may match the medication information if the content of the medicine container complies with the prescription, and thus the system may generate a notification or alert indicating compliance. The container information may not match the medication information if the contents of the medicine container do not comply with the prescription, and thus the system may generate a notification or alert indicating non-compliance. Accordingly, the systems herein may compare the prescription information and the container information to determine medication compliance or non-compliance.
Embodiments may utilize and compare multiple types of information, e.g., related information received from distinct sources, including, but not limited to, hospitals, pharmacies, doctors' offices, the National Drug Code (NDC), and the like. For example, the system may receive information associated with a prescription (e.g., as defined by a user such as medical professional or patient), a medication or medicine (e.g., as defined by the contents of a medication container or by a manufacturer), and a medication container (e.g., as defined by the size and shape of the container or as labeled on the container). These types of information should be the same if everything was entered and received correctly, but because the information is input separately, the information from various sources may not be the same. For example, errors may be introduced by way of manual inputs, user mismatches, computer transfer, RF reader, OCR, etc. As such, the system herein leverages the information from various sources to increase the accuracy of the medication actually taken by the patient. More specifically, the information is received from distinct sources and compared to determine compliance or non-compliance, thereby reducing the likelihood of error with multiple ways of receiving the same types of information. Depending on whether there is a match or mismatch, the system may alert or notify the user regarding the same to reduce the possibility of the patient taking the wrong medication. Accordingly, the system may be advantageous in increasing the effectiveness of treatment, e.g., by information redundancy and monitoring information with respect to at least two sources.
System 100 may further include at least one of a device 103, a server 104, a network 118, a database 122, and connections 124. An exemplary device 103 may include any computing device including, but not limited to, a mobile device, cellular phone, smartphone, tablet computer, next generation portable device, handheld computer, notebook, or laptop. The device 103 may include a processor 106 that executes program 110 to provide the operations herein. The device 103 may include a memory 108 that stores medication information and program 110. The device 103 may include a communication device 116 that communicates with at least one of the dispensing device 102, the assemblies 150-170, server 104, network 118, and database 122. The device 103 may provide operations to and control the functionality of the dispensing device 102. In addition or alternatively, the dispensing device 102 may be controllable via its own processor 106.
Server 104 may include any computing system. For example, server 104 may include a user profile server for generating and storing a user profile for each user, server 104 may be configured to generate and store medication information. The server 104 may be configured to communicatively connect with and transfer medication information between with respect to any of dispensing device 102 and assemblies 140, 150 a-d, 160, and/or 170, network 118, and database 122. Server 104 may be in continuous or periodic communication with dispensing device 102, assemblies 140-170, network 118, and/or database 122. Server 104 may include a local, remote, or cloud-based server or a combination thereof and may be in communication with and provide medication information (e.g., as part of memory 108 or database 122) to any of dispensing device 102, assemblies 102-170, network 118, and/or database 122. The server 104 may further provide a web-based user interface (e.g., an internet portal) to be displayed by display 112. The server 104 may communicate the medication information with dispensing device 102, assemblies 140-170, network 118, and/or database 122 using a notification. In addition, server 104 may be configured to store medication information as part of memory 108 or database 122. Server 104 may include a single or a plurality of centrally or geographically distributed servers 104. Server 104 may be configured to store and coordinate medication information with any portion of the systems herein.
The system 100 may include an overall network infrastructure through which the dispensing device 102, assemblies 140-170, server 104, and database 122 may communicate, for example, to transfer medication information between each other, e.g., using connections 124. In general, a network (e.g., system 100 or network 118) may be a collection of computing devices and other hardware to provide connections and carry communications. As an example, each device may communicate with every other device through the use of a wired or wireless network or a combination thereof, e.g., using any wired or wireless connection including direct wiring, Ethernet wiring, radio frequency (RF), cellular phone service, GPS, Bluetooth, infrared (IR) signals, or any other connection.
The connections 124 may be any wired or wireless connections between two or more endpoints (e.g., devices or systems), for example, to facilitate transfer of medication information. Connections 124 may include a local area network (LAN) connection, for example, to communicatively connect the devices/assemblies 102-170, server 104, and database 122 with network 118. Connections 124 may include a wide area network (WAN) connection, for example, to communicatively connect server 104 with network 118. Connections 124 may include a radiofrequency (RF), near field communication (NFC), Bluetooth®, Wi-Fi, or a wired connection, for example, to communicatively connect assemblies 102-170.
Referring to FIG. 2, dispenser or dispensing device 102 of FIG. 1 is shown. Dispenser 102 includes a display 200, an input device 202, a loading door or medicine container loading station door (MCLSD) 204, a storage container or medicine storage container (MSC) 206, and a loading station or medicine container loading station (MCLS) 208. Display 200 may be used to present, illustrate or display medication information including, for example, instructions for operation of dispenser 102. The medication information, e.g., on display 200, may include instructions to prepare one or more storage containers 206 having a medical dose for a patient or user. Medicine container loading station 208 may rotate medicine storage container 206 on a carousel so that a machine vision system or a scanner 220, for instance, to take images (e.g., 360 degree pictures) of medicine storage container 206 to read information from a label on MSC 206. MSC 206 may be operated automatically or manually, may be operated by user inputs to display 200 or a button on a face 210 of dispenser 100, or may be operated via input device 202. Machine vision system 220 may be positioned to view within MCLSD 204 so that a position of MSC 206 and other storage devices therein may be determined.
FIG. 3 is a perspective view of an exemplary sub-assembly 300 illustrating the disclosed system or dispenser. Sub-assembly 300 is a view of inside elements of dispenser 102 and includes a carousel 310. Sub-assembly 300 includes a loading station or MCLS 325, a first transfer device or first medicine container transfer unit (MCTU) 330, and a storage device or medicine container storage nest (MCSN) 335. A loading point or medicine container loading point (MCLP) 340 may be proximate a second transfer device or second medicine container transfer unit (MCTU) 345. A first medicine discharge point (MDP) 350 includes, for example, a medicine transfer unit (MTU) 355 that may include a ramp or conveyor for transporting or otherwise conveying medicine from medicine container transfer unit 345 to a second medicine discharge point (MDP) 380. MTU 355 may include one or more devices for measuring a weight or amount of medicine positioned thereon, as will be further described in further examples. Sub-assembly 300 includes a weight checking station (WCS) 360, dispensed medicine container (DMC) 365, medicine transfer containers (MTC) 370 and 375. Weight checking station 360 may determine an amount of weight contained thereon. Sub-assembly 300 includes a calibration and verification device 382 to automatically calibrate weight detecting devices. The calibration and verification device 382 may include, but is not limited to, a calibrator, and multiple calibration weights with different masses.
The system may include and utilize one or a plurality of dispensed medicine containers (DMC). For example, a first medicine container may have a final or prescribed dosage for patient to take and a second medicine container may be for system to use to transfer medicine. Medicine transfer unit (MTU), medicine transfer container (MTC), dispensed medicine container (DMC), and medicine storage containers (MSC) may or may not be separated physical devices. The medicine containers may have any shape, size, and may differ from those illustrated. One device or container may have multiple functions. The Medicine Storage Container (MSC) may include an original or standard container received with medicine from pharmacies, hospitals, etc., the medicine storage container may be integrated with or provided with the system, or may be a combination thereof. The medicine transfer unit (MTU) may have different forms and designs, may be a chute, a container of any shape, a plate, a conveyor, a moving surface, a robot, a sub assembly (machine), although examples of the medicine transfer unit are shown in examples as a linear conveyor and a rotating disc. A medicine quantity sensing unit may include visual sensors, or any monitoring device that may count or otherwise determine a quantity of medicine, and may include scales, load cells, sensors, images, and other means. The medicine container transfer unit (MCTU) moves the medicine containers. The devices herein may have many different forms and designs, including a conveyor, a carousel, a robot, a walking beam, a dial table, a rotary table, a sub assembly (machine). The systems herein may have multiple layers (such as additional medical transfer units (MTUs), and may have multiple carousels.
In addition, in one example, containers used are original containers received from, for instance, a pharmacy with the medicine. However, the system may have its own containers and the system transfers medicines from the original containers to the system containers. As such, the system may keep original containers. The disclosed system can transfer medicines back from system containers to original containers if needed, e.g., switch to a different medicine because of, for instance, any allergy to a medicine.
The disclosed system may have a cleaning device to clean the surfaces after each dispensing cycle for those surfaces contacted with medicine during the disclosed dispensing processes.
During operation a user may attach medicine container identification unit 385 to original medicine container 390, and together they form medicine storage container 320. Medicine container identification unit 385 may be a physical device, a RF tag, a near field communication (NFC) device, a bar code, a sensor, and the like. Medicine container storage nest 335 is able to communicate wirelessly with medicine container identification unit 385 and can both read and write information. Medicine container storage nest 335 is also able to communicate with the control unit of the dispenser 100, and medicine container storage nest 335 may have, for instance, memory 108.
Referring back to FIG. 3, medicine storage container 320, or original medicine container 390, either of which may have medicine provided from for instance a pharmacy, may be loaded into dispenser 102 from medicine container loading station 325, and medicine storage container 320 is transferred to medicine container loading point 340 by medicine container transfer unit 330. Medicine storage container 320 may include medicine in the form of a pill or a capsule, as examples, and a dose of medicine for a user may include one or more of the pills or capsules. Medicine container transfer unit 330 is illustrated as having carousel 310, but may instead include a conveyor, a robot, or any device that can move medicine storage container 320 from one position to another, and discharge medicine from medicine storage container 320.
Medicine transfer unit 355 moves medicine from one position to another, accepts medicine from medicine storage container 320, and medicine transfer unit 355 also discharges medicine into medicine storage container 320 or any container when positioned at medicine discharge point 380. Medicine transfer unit 355 may have a linear moving surface such as a walking beam, a conveyor, or a rotating surface such as a rotating disc or other shape.
In operation, dispenser 102 moves, via carousel 310, medicine storage container 320 to a loading point 312, and loading point 312 is proximate medicine container transfer unit 345. Medicine container transfer unit 345 engages with medicine storage container 320 by attaching thereto, and moving medicine storage container 320 to first medicine discharge point 350. Medicine storage container 320 is, in one example, a medicine storage container which may have an amount of medicine that is in excess of a dose, or an amount of medicine that is desired to be distributed into dispensed medicine container 365. Medicine container transfer unit 345 turns medicine storage container 320 such that at least a predetermined amount of medicine spills or otherwise pours from medicine storage container 320 onto medicine transfer unit 355. Carousel 310 may rotate to move medicine transfer container 370 to second medicine discharge point 380. When medicine transfer container 370 is positioned at medicine discharge point 380, and when medicine has been discharged onto medicine transfer unit 355, medicine transfer unit 355 thereby conveys the discharged medicine from medicine transfer unit 355 into medicine transfer container 370 until at least a second predetermined amount of medicine is contained in medicine transfer container 370, as determined by weight determining device 395 and medicine container storage nest 335, which weigh and transmit weight information to for instance a controller of dispenser 102. Other methods may be used to determine amount of medicine is contained in medicine transfer container 370, e.g. sensor, and image.
Medicine is transferred from medicine transfer unit 355 into medicine transfer container 370, and a weight of the medicine is determined via weight determining device 395. If the measured weight is less than a given or desired dose, and if medicine is still on medicine transfer unit 355 (i.e., has not been fully discharged), then medicine transfer unit 355 further conveys more medicine into medicine transfer container 370. On the other hand, if no medicine is on medicine transfer unit 355, then additional medicine is discharged to medicine transfer unit 355 from medicine storage container 320. The process of discharging from medicine storage container 320 to medicine transfer unit 355, and from medicine transfer unit 355 to medicine transfer container 370 continues until at least a dose of medicine is contained in medicine transfer container 370. That is, medicine transfer container 370 may include an exact or desired dose, or may include an amount of medicine that is in excess of an exact dose.
If an exact dose is present in medicine transfer container 370, then dispenser 102 operates to convey medicine transfer container 370 to first medicine discharge point 350 via medicine container transfer unit 345, any remaining medicine on medicine transfer unit 355 is discharged back into medicine storage container 320 at second medicine discharge point 380, and the medicine in medicine transfer container 370 is discharged into dispensed medicine container 365 that is positioned at second medicine discharge point 380.
On the other hand, in one example medicine transfer container 370 may include an amount of medicine that is in excess of an exact dose. In such an example, medicine transfer container 370 is thereby conveyed to first medicine discharge point 350 and operations described above are repeated. That is, medicine container transfer unit 345 discharges medicine from medicine transfer container 370 onto medicine transfer unit 355, and medicine transfer container 375 is conveyed via carousel 310 to second medicine discharge point 380. Medicine discharged from medicine transfer container 370 to medicine transfer unit 355 is thereby conveyed to medicine transfer container 375 until at least the exact dose is present in medicine transfer container 375. And, again, if medicine transfer container 375 includes medicine equal to the dose, then the medicine in medicine transfer container 375 is discharged into dispensed medicine container 365, and any excess medicine on medicine transfer unit 355 is returned to medicine storage container 320.
The aforementioned steps continue until a dose of medicine is contained within dispensed medicine container 365, and any additional medicine is returned to medicine storage container 320. In such fashion, dispenser 102 includes a feedback mechanism, ensuring a proper dose, and only a proper dose, is contained in dispensed medicine container 365. That is, feedback is provided in the form of a weight of pills or capsules, corresponding to a dose, measured via weight detecting device 395. The feedback may also be provided in other forms, e.g. pill numbers determined by sensors, or images. Dispenser 102 is caused to operate using such feedback to ensure that a correct dose is provided in dispensed medicine container 365.
Referring now to FIG. 5, a schematic diagram of a system 500 of the interaction between system 100, users 502-508, and databases 510-516. The users may include, but are not limited to, family member(s) 502, caregiver(s) 504, doctor(s) 506, and other(s) 508. The databases may include, but are not limited to, cloud storage 510, hospital(s) 512, e.g., hospital servers or databases, remote server(s) 514, which may include, but is not limited to, server 104, National Drug Code (NDC) database(s), and the like, and pharmacy(ies) 516.

The hardware structure may include control unit or processor 106, memory 108, display 112, I/O device(s) 114, communication device 116, and a power device 118. The processor 106 may be any type of general or specific purpose processor, including, but not limited to, a controller. The power device 118 may be configured to either AC and or DC power, such as a lithium ion battery system. If the system 100 uses rechargeable batteries, the power source may monitor the power remaining and give reminder signals to recharge batteries once the batteries are low. The memory 108 may store medication information including prescription information, medicine container identification information and patient's medical history information. The I/O device 114 may include, but is not limited to, an RF reader, one or more cameras, scanner, barcode reader (e.g., 1d or 2d), one or more lights, one or more sensors, one or more speakers, one or more buttons, keyboard, mouse, touch screen, microphone, one or more scales, or a combination thereof.
The communication device 116 may communicatively connect the devices of system 100 or 500, for example, using any type of wired or wireless network connection. The communication device 116 may include a single transceiver or a combination of transmitters and receivers.

Referring now to FIG. 6, a flow diagram of an exemplary process 600 for setting up the system 100 is illustrated. Process 600 may include operations that may be part of program 110 stored on memory 108, and/or executed by processor 106. Process 600 may take many different forms and include multiple and/or alternate steps. While an exemplary process is shown, the exemplary steps illustrated are not intended to be limiting. Indeed, additional or alternative steps and/or implementations may be used.
Process 600 may begin at block 602 at which a medicine container identification unit 385 is added to an original medicine container 390. The combination of the medicine container identification unit 385 and the medicine container 390 collectively form the medicine storage container 320. Alternatively, process 600 may implement the original medicine container 390 without the medicine container identification unit 385.
At block 604, prescription information associated with the patient may be inputted into the device 100. The information may include, but is not limited to, the patient's name, name of the drug, strength of the drug, direction for use, including, but not limited to, a schedule and/or quantity to take, quantity in the medicine container 390, and the like. The information may be inputted via different methods and/or technologies, as illustrated in FIG. 7 and described below.
At block 606, the processor 106 may prompt the user to place the medicine storage container 320 into the loading station 325. The prompt may be verbal, for example, via speaker(s) of the I/O device(s) 114, and/or visual, for example, via the display 112. The user may then place the medicine storage container 320 into the loading station 325.
At block 608, the loading station door 204 may close. This may be done automatically, for example, but not intended to be limiting, after a set amount of time has passed after the prompt to place the medicine storage container 320 into the loading station 325, or upon sensing that the medicine storage container 320 has been placed into the loading station 325. Alternatively, the loading station door 204 may be manually closed by the user, for example, but not intended to be limiting, sliding the door closed or pressing a button designated for closing and/or opening the door.
At block 610, medicine container information may be inputted. The information may include, but is not limited to, the patient's name, name of the drug, strength of the drug, direction for use, including, but not limited to, a schedule and/or quantity to take, quantity in the medicine container 390, and NDC information for the medicine/drug. The information may be inputted via different methods and/or technologies, as illustrated in FIG. 8 and described below.
At block 612, the processor 106 may determine if the prescription and the medicine storage container 320 match, for example, by comparing the prescription information and the medicine container information. If they do not match, process 600 may proceed to block 614 at which the processor 106 may prompt the user if the medicine storage container 320 is correct.
If the medicine storage container 320 is correct, process 600 may proceed to block 616 at which the processor 106 may provide a warning message, verbally and/or visually, for example, of the discrepancy between the prescription and the medicine storage container 320, after which process 600 may end.
If the medicine storage container 320 is not correct, process 600 may proceed to block 618 at which the processor 106 may prompt the user to take the correct medicine storage container 320, which includes the correct medicine container 390, and place it into the loading station 325 after removing the incorrect medicine storage container 320. Process 600 may then proceed back to block 608 at which the loading station door 204 may be closed. Blocks 610 and 612 may be repeated, or alternatively, process 600 may end after the repeating of block 608.
Referring back to block 612, if the prescription and the medicine storage container 320 do match, then process 600 may proceed to block 620 at which a first medicine container transfer unit 330 of the dispensing unit 102 may transfer the medicine storage container 320 to a storage location.
At block 622, the processor 106 may remember the container identification and the storage location of the medicine storage container 320, for example, by storing the information in the memory 108.
At block 624, the processor 106 may determine if all medicine storage containers 320 and/or medicine containers 390 for the prescription are finished. This may be determined from the prescription information obtained at block 608. In addition or alternatively, the processor 106 may prompt the user, verbally and/or visually, if all medicine storage containers 320 for the prescription are finished, to which the user may respond tactilely and/or verbally. If the answer is no, process 600 may proceed back to 606 at which the processor 106 may prompt the user to place the next medicine storage container 320 into the loading station 325, after which the subsequent blocks of process 600 may be repeated.
If all the containers are finished for the prescription, process 600 may proceed to block 626 at which the processor 106 may prompt the user, verbally and/or visually, if there are any more prescriptions, to which the user may respond tactilely and/or verbally. If there are more prescriptions, process 600 may proceed back to block 604 at which the prescription information for the new prescription may be inputted into the device 100, after which the subsequent blocks of process 600 may be repeated.
If there are no more prescriptions, process 600 may proceed to block 628 at which the control unit processor may update the prescription(s) into the patient's account, which, again, may be stored locally in the memory 108 and/or remotely at any one of the databases 510-516.
At block 630, the processor 106 may retrieve weight for each pill or capsule from databases 510-516. Alternatively, the processor 106 may run dispenser unit to calculate the weight. The processor 106 may also check the weight of the medicine in a container to verify the medicine in the container is correct. At block 632, the processor 106 may run cleaning logic to clean surfaces contact with medicine according predetermined schedules or as required. At block 634, the processor 106 may run calibration and verification logic to calibrate or verify weight detecting devices according to predetermined schedules as required. At block 636, the processor 106 may run vision system logic to take images of a medicine and compare them to the image retrieve from databases 510-516 to verify medicine in the container is correct.
At blocks 638-642, any one of the assemblies 140, 150 a-d, 160, and 170 and the dispensing unit 102 may now operate according to any one of the processes described in U.S. patent application Ser. Nos. 15/613,675 and 15/613,852 and further below with respect to FIGS. 8-10, 12, 14, 16, 18, and 20.
At block 644, the processor 106 runs dispenser logic as described herein After block 644, the process may repeat or end.
Referring now to FIG. 7, a flow diagram of an exemplary process 700 for inputting prescription information is illustrated. Process 700 may include operations that may be part of program 110, stored on memory 108, and/or executed by processor 106, Process 700 may take many different forms and include multiple and/or alternate steps. While an exemplary process is shown, the exemplary steps illustrated are not intended to be limiting. Indeed, additional or alternative steps and/or implementations may be used.

With respect to input mode 714, the user may read the prescription via a microphone of the I/O device(s) 114, as illustrated in block 714 a.
At block 716, the processor 106 may present the prescription information back to the user verbally and/or visually. For example, the processor 106 may read the prescription information via speaker(s) of the I/O device(s) 114 and/or display the prescription information on the display 112. The user may then verify the information tactilely, for example, via a keyboard of the I/O device(s) 114, which, again, may be a standalone keyboard or a touch screen keyboard, and/or verbally, for example, via a microphone of the I/O device(s) 114.
At block 718, the processor 106 may determine if the medicine is new for the patient. This may be determined by prompting the user, which, again, may be verbally via speaker(s) of the I/O device(s) 114, or visually on the display 112. In addition or alternatively, the processor 106 may compare the name of the medicine with a list of prior and/or current medicines stored in the patient's account.
If the medicine is not new, process 700 may proceed to block 720 at which the processor 106 may determine if the schedule included with the prescription information is new. This, again, may be determined by prompting the user and/or comparing the schedule to an existing schedule stored in the patient's account. If the schedule is not new, process 700 may end. If the schedule is new, process 700 may proceed to block 722 at which the processor 106 may warn the user of the schedule change, and block 724 at which the user may acknowledge the change, after which process 700 may end.
If the medicine is new, process 700 may proceed to blocks 726 and 728 at which the processor 106 may check whether the prescription information is consistent with the NDC database(s) and/or the patient's records, and determine if there are any conflicts. If there are no conflicts, then process 700 may end. If there are conflicts, process 700 may proceed to blocks 730 and 732 at which the processor 106 may provide a warning message, verbally and/or visually, and the user may acknowledge the warning, tactilely or verbally, after which process 700 may repeat or end.

Referring now to FIGS. 9A and 9B, a flow diagram of an exemplary process 900 is illustrated. Process 900 may be for operating the dispensing unit 102, e.g., moving a dose (or other predetermined amount) of medicine to a storage container. Process 900 may include operations that may be part of program 110, stored on memory 108 or database 122, and/or executed by processor 106. Process 900 may take many different forms and include multiple and/or alternate steps. While an exemplary process is shown, the exemplary steps illustrated are not intended to be limiting. Indeed, additional or alternative steps and/or implementations may be used. In addition, process 900 may be applicable, in whole or in part, to each of processes 1000, 1200, 1400, 1600, 1800, 2000, and 2200 and the specific embodiments of the dispensing unit 102 incorporated therein, as described in more detail hereinafter.
At block 902, processor 106, e.g., by way of first medicine container transfer unit 330, may move the medicine storage container 320 from an initial position, e.g., the storage position, to the medicine container loading point 340, which may be stored on and received from memory 108 or database 122. The moving of the medicine storage container 320 may be performed by the first medicine container transfer unit 330, and may generally be in a circumferential direction, as illustrated in FIG. 3. However, it should be appreciated that the medicine storage container 320 may be moved to the loading point 340 in any linear or non-linear direction.
At block 904, the processor 106 may move, e.g., by way of the second medicine container transfer unit 345, the medicine storage container 320 from the loading point 340 to a first discharge point 350, which may be stored on and received from memory 108 or database 122. The moving of the medicine storage container 320 may generally be in a vertical direction such that it may be elevated above the medicine transfer unit 355.
At block 906, the processor 106 may move, e.g., by way of the first medicine container transfer unit 330, a first medicine transfer container, which may be either medicine transfer container 370 or 375 from an initial position to a second discharge point 380, which, as explained above, may be located at an end of the medicine transfer unit 355 to receive the medicine. The moving of the first medicine transfer container 370, 375 generally may be in a circumferential direction, as illustrated in FIG. 3. However, it should be appreciated that the first medicine transfer container 370, 375 may be moved to the second discharge point 380 in a linear direction.
At block 908, the processor 106 may discharge, e.g., by way of the second medicine container transfer unit 345, at least a first predetermined amount of medicine from the medicine storage container 320 onto the medicine transfer unit 355. The predetermined amount may change during the dispensing process. It should be appreciated that the processor 106 may discharge the medicine from the medicine storage container 320 via any known mechanism or device, which may rotate, tilt, or otherwise move the medicine storage container 320.
At block 910, the processor 106 may discharge, e.g., by way of the medicine transfer unit 355, at least a second predetermined amount of the medicine on the medicine transfer unit 355 therefrom into the medicine transfer container 370, 375. The second predetermined amount may or may not be the same as the first predetermined amount, and may change during the dispensing process.
At block 912, the dispensing unit 102, by way of the processor 106, may determine if the medicine in the first medicine transfer container 370, 375 is equal to the required dosage, as determined and stored in the memory 108 in process 600. If the medicine does equal the required dosage, then process 900 may proceed to blocks 914 and 916. If not, then process 900 may proceed to block 918.
At block 914, the processor 106 may move, e.g., by way of the first medicine container transfer unit 355, the medicine in the first medicine transfer container 370, 375, which is in the required dosage amount, to the dispensed medicine container 365 at the second discharge point 380. At block 916, the processor 106 may move, e.g., via the medicine transfer unit 355, all the remaining medicine on the medicine transfer unit 355 and/or the first medicine transfer container 370, 375 back to the medicine storage container 320 by various rearranging of the dispensed medicine container 365 and medicine storage container 320 from and to the second medicine discharge point 380. Process 900 may end after block 916.
At block 918, the dispensing unit 102, for example, the processor 106, may determine if the medicine on the medicine transfer unit 355 is equal to the required dosage. If the medicine does equal the required dosage, then process 900 may proceed to blocks 914 and 916 described above. If not, then process 900 may proceed to block 920.
At block 920, the dispensing unit 102, for example, the processor 106, may determine if the medicine in the first medicine transfer container 370, 375 is less than the required dosage. If it is less, then process 900 may proceed to block 922 at which the dispensing unit (e.g., the processor 106) may determine if there is still medicine on the medicine transfer unit 355. If there is not, process 900 may go back to block 908. If there is, process 900 may go back to block 910.
If the medicine in the first medicine transfer container 370, 375 is not less than the required dosage, as may be determined at block 920, process 900 may proceed to blocks 924 and 926 at which the processor 106 may move the medicine storage container 320 to the second discharge point 380, and the first medicine transfer container 370, 375 to the first discharge point 350. Blocks 924 and 926 may occur simultaneously or one after the other.
At block 928, the processor 106 may discharge any remaining medicine on the medicine transfer unit 355 into the medicine storage container 320.
At block 930, the processor 106 may move a second medicine transfer container, which may be the other of medicine transfer containers 370 and 375, to the second discharge point 380.
After block 930, process 900 may go back to block 908, where the first medicine transfer container 370, 375 may act as the medicine storage container 320, and the second medicine transfer container 370, 375 may act as the first medicine transfer container 370, 375. Accordingly, medicine may be discharged from the first medicine transfer container 370, 375 to the second medicine transfer container 370, 375, and medicine storage container 320.
Process 900 may be iterated until the medicine in the dispensed medicine container 365 equals the required dosage, as described below.
In general, the processes herein (e.g., process 900) may involve different combinations of medicine in one or two units. The combinations may include, but are not limited to, the first medicine transfer container 370, 375 alone, the second medicine transfer container 370, 375 alone, the medicine transfer unit 355 alone, the first and second medicine transfer containers 370, 375, the first medicine transfer container 370, 375 and the medicine transfer unit 355, and the second medicine transfer container 370,375 and the medicine transfer unit 355. Those combinations may change for every iteration. The process 900 determines the most optimal way to dispense for every iteration.
As described in more detail with respect to processes 1000, 1200, 1400, 1600, 1800, 2000, and 2200, the processor 106 may communicate with, i.e., send commands to, receive data from, and the like, to various components of the dispensing unit 102 and/or system 500 to perform the different steps of process 900. In addition or alternatively, the various components may communicate directly with each other.
Referring now to FIG. 10, a flow diagram of another exemplary process 1000 for operating the dispensing unit 102 is illustrated, which may incorporate the sub-assembly 300. Process 1000 may include operations that may be part of program 110, stored on memory 108, and/or executed by processor 106. Process 1000 may take many different forms and include multiple and/or alternate steps. While an exemplary process is shown, the exemplary steps illustrated are not intended to be limiting. Indeed, additional or alternative steps and/or implementations may be used.
Process 1000 may begin at step 1002 at which the first medicine container transfer unit 330 may transfer the medicine storage container 320 from its storage location, e.g., the loading station 325, to the medicine container loading point 340 for the second container medicine transfer unit 345. This may be done in a generally circumferential direction, for example, where the first medicine container transfer unit 330 is a carousel, or in a generally linear direction.
At block 1004, the second medicine container transfer unit 345 may transfer the medicine storage container 320 to a first discharge point 350. This may be in a generally vertical direction such that the medicine storage container 320 may be elevated above the medicine transfer unit 355.
At block 1006, the second medicine container transfer unit 345 may discharge medicine from the medicine storage container 320 onto the medicine transfer unit 355. This may be achieved by rotating the medicine storage container 320, which may be steady or intermittent. It should be appreciated that other ways to discharge the medicine from the medicine storage container 320 onto the medicine transfer unit 355 are contemplated.
At block 1008, the second medicine container transfer unit 345 may stop discharging when the medicine transfer unit 355 detects at least a predefined amount of medicine discharged on it, which may or may not be the required dosage. For example, the medicine transfer unit 355 may include one or more sensors that detect weight, area, volume, or any other characteristic by which an amount of medicine on the medicine transfer unit 355 may be determined. The medicine transfer unit 355 may then communicate, e.g., send a signal, directly to the second medicine container transfer unit 345 to stop discharging, or indirectly by sending a signal to the processor 106 that the predefined amount of medicine has been detected, the processor 106 in turn commanding the second medicine container transfer unit 345 to stop discharging.
At block 1010, the first medicine container transfer unit 330 may transfer a first medicine transfer container 375 to a second medicine discharge point 380, which may be, but is not limited to, at an end of the medicine transfer unit 355. The medicine transfer unit 355 may then begin discharging the medicine on it into the medicine transfer container 375.
At block 1012, the medicine transfer unit 355 may stop discharging the medicine.
At block 1014, the processor 106 may determine if the medicine inside the first medicine transfer container 375 is less than the required dosage, i.e., the same as or more than the required dosage. In one exemplary approach, this may be determined by measuring the weight of the medicine in the first medicine transfer container 375 by the scale 395 on which the first medicine transfer container 375 may be disposed. The scale 395 may then transmit data representing the measured weight to the processor 106, which may then compare the measured weight with a weight corresponding to the medicine in the required dosage, which may be stored locally on the memory 108 and/or remotely at any one of the databases 510-516.
If the medicine inside the first medicine transfer unit is not less than the required dosage, then process 1000 may proceed to block 1016. If it is less, then process 1000 may repeat blocks 1006 to 1012 until the amount of medicine inside the first medicine transfer container 375 is not less than the required dosage. Then process 1000 may proceed to block 1016.
At block 1016, the medicine container transfer units 330 and 345 may transfer the medicine storage container 320 to the second medicine discharge point 380. For example, the second medicine container transfer unit 345 may lower the medicine storage container 320 back to a plane of the first medicine container transfer unit 330, which may, in turn, rotate or otherwise move the medicine storage container 320 to the second medicine discharge point 380.
At block 1018, the medicine transfer unit 355 may discharge all the remaining medicine on it back into the medicine storage container 320.
At block 1020, the medicine container transfer units 330 and 345 may move the first medicine transfer container 375 to the first medicine discharge point 350. If the medicine in the first medicine transfer container 375 is equal to the required dosage, process 1000 may proceed to block 1022. If the medicine in the first medicine transfer container 375 is greater than the required dosage, process 1000 may proceed to block 1024.
At block 1022, the first medicine container transfer unit 330 may transfer the dispensed medicine container 365 to the second medicine discharge point 380. The second medicine container transfer unit 345 may then transfer all the medicine in the first medicine transfer container 375 onto the medicine transfer unit 355, which, in turn, may then transfer the medicine into the dispensed medicine container 365. Process 1000 may end after this step.
At block 1024, the first medicine container transfer unit 330 may transfer the second medicine transfer container 370, to the second medicine discharge point 380. The second medicine container transfer unit 345 may then discharge medicine from the first medicine transfer container 375 onto the medicine transfer unit 355, which, in turn, may begin transferring medicine into the second medicine transfer container 370. The processor 106 may then determine if the medicine inside the first medicine transfer container 375, the second medicine transfer container 370, or the combination of the medicine transfer containers 370, 375 is equal to or greater than the required dosage. If it is equal, process 1000 may proceed to blocks 1026 and 1028. If it is greater, process 1000 may proceed to blocks 1030 and 1032.
At block 1026, the medicine container transfer unit 345 and the medicine transfer unit 355 may both stop discharging.
At block 1028, medicine in the first medicine transfer container 375, the second medicine transfer container 370, or both that equals the required dosage may be discharged into the dispensed medicine container 365. The remaining amount of medicine, which may be in the first medicine transfer container 375 and/or on the medicine transfer unit 355, may be discharged back into the medicine storage container 320. Both medicine transfer containers 370, 375 should be empty after this step. Process 1000 may end after this step.
At block 1030, the medicine transfer unit 355 may stop discharging medicine into the second medicine transfer container 370. The remaining medicine may be discharged back into the medicine storage container 320.
Blocks 1020 through 1030 may be repeated until the medicine in the first medicine transfer container 375, the second medicine transfer container 370, or the combination of the medicine transfer containers 370, 375 equals the required dosage in block 1026. Process 1000 may end after the final iteration of block 1026.
Process 1000 may be repeated for the next medicine when required.
In general, process 1000 may be a closed feedback loop process with stable and fast convergent iterations. In addition, the processor 106 may communicate with, i.e., send commands to, receive data from, and the like, to various components of the dispensing unit 102 and/or system 500 to perform process 1000, and to decide the best way to distribute the medicine among medicine storage container 320, the medicine transfer containers 370, 375, and the dispensed medicine container 365 based on process 1000.
FIG. 11A illustrates an exemplary sub-assembly 1100 of the disclosed system. FIG. 11B illustrates the exemplary system of FIG. 11A during operation. FIG. 11C illustrates a top view of the exemplary system of FIGS. 11A and 11B. FIG. 11A illustrates the disclosed dispenser having a conveyor 1105, a robot 1120, and carousel 310. In this example medicine container transfer unit 330 includes carousel 310, medicine container transfer unit 345 includes robot 1120 having an end of arm tool 1125, medicine transfer unit 355 having a conveyor 1105 and sensors 1110 and 1115. FIG. 11B is a view of sub-assembly as shown in FIG. 11A, showing medicine storage container 320 transferred to first medicine discharge point 350 by medicine container transfer unit 345 to discharge medicine from medicine storage container 320 to conveyor 1105. Sensors 1110 and 1115 monitor medicine positioned on medicine transfer unit 355 and more specifically on conveyor 1105.
FIG. 11A illustrates an exemplary sub-assembly 1100 illustrating the disclosed system or dispenser. Sub-assembly 1100 is a view of inside elements of dispenser 102 and includes carousel 310. Sub-assembly 1100 includes loading station or medicine container loading station 325, first medicine container transfer unit 330, and medicine container storage nest 335. Medicine container loading point 340 is proximate second medicine container transfer unit 345. First medicine discharge point 350 includes, in the illustrated example, medicine travel unit 355 that may include conveyer 1105 for transporting or otherwise conveying medicine from medicine container travel unit 345 to second medicine discharge point 380, and may include sensors 1110 and 1115. Sub-assembly 1100 includes weight checking station 360, dispensed medicine container 365, a calibration and verification device 382 to automatically calibrate weight detecting devices, and medicine transfer containers 370 and 375. Medicine storage container 320 is positioned on carousel 310.
Referring to FIGS. 11A-C, FIG. 11A is an illustration of medicine storage container 320 as positioned proximate medicine container transfer unit 345, and FIG. 11B the exemplary system of FIG. 11A during operation. Medicine storage container 320 may include original medicine container 390, medicine container identification unit 385, weight detecting device 395, and medicine container storage nest 335. Weight detecting device 395 and medicine container storage nest 335 may be integrated together. Weight detecting device 395 and medicine container storage nest 335 may also be part of carousel 310. Weight detecting device 395 may be a scale, a load cell, or other device for measuring weight, according to the disclosure. Weight detecting device 395 and medicine container storage nest 335 are positioned about carousel 310 at each of the illustrated locations. Medicine container identification unit 385 may include identification information particular to a given medicine, and may also identify an amount of medicine that may constitute a single patient dose particular to a given user of dispenser 102.
Referring still to FIG. 11A, medicine storage container 320 may be loaded into dispenser 102 from medicine container loading station 325, and medicine storage container 320 is transferred to medicine container loading point 340 by medicine container transfer unit 330. Medicine storage container 320 may include medicine in the form of a pill or a capsule, as examples, and a dose of medicine for a user may include one or more of the pills or capsules. Medicine container transfer unit 330 is illustrated as having carousel 310, but may instead include a conveyor, a robot, or any device that can move medicine storage container 320 from one position to another, and discharge medicine from medicine storage container 320.
Medicine transfer unit 355 moves medicine from one position to another, accepts medicine from medicine storage container 320, and medicine transfer unit 355 also discharges medicine into medicine storage container 320 or any container when positioned at medicine discharge point 380. Medicine transfer unit 355 may have a linear moving surface such as a walking beam, a conveyor, or a rotating surface such as a rotating disc or other shape.
In operation, as shown in FIGS. 11A and 11B, dispenser 102 moves, via carousel 310, medicine storage container 320 to loading point 312, and loading point 312 is proximate medicine container transfer unit 345. Medicine container transfer unit 345 engages with medicine storage container 320 by attaching thereto, and moving medicine storage container 320 vertically to first medicine discharge point 350. Medicine storage container 320 is, in one example, a medicine storage container which may have an amount of medicine that is in excess of a dose, or an amount of medicine that is desired to be distributed into dispensed medicine container 365. Medicine container transfer unit 345 turns medicine storage container 320 such that a predetermined amount of medicine spills or otherwise pours from medicine storage container 320 onto medicine transfer unit 355. Carousel 310 rotates to move medicine storage container 370 to second medicine discharge point 380. When medicine transfer container 370 is positioned at medicine discharge point 380, and when medicine has been discharged onto medicine transfer unit 355, medicine transfer unit 355 thereby conveys the discharged medicine from medicine transfer unit 355 into medicine transfer container 370 until at least a second predetermined amount of medicine is contained in medicine transfer container 370, as determined by weight detecting device 395 and medicine container storage nest 335, which weigh and transmit weight information to for instance a controller of dispenser 102.
Medicine transfer unit 355 includes conveyor 1105, and sensors 1110 and 1115, which monitor medicine positioned on medicine transfer unit 355 and on conveyor 1105. Sensors 1110, 1115 may be optical sensors that are coupled, electrically or optically as examples, to processor 106. As such, processor 106 monitors an amount of medicine positioned on medicine transfer unit 355 via sensors 1110, 1115.
FIG. 11C illustrates a top view of the exemplary system of FIGS. 11A and 11B, and shows medicine storage container 320 turned such that at least a predetermined amount of medicine spills or otherwise pours from medicine storage container 320 onto medicine transfer unit 355. Sensors 1110 and 1115 detect the presence of pills or capsules 1125 as they pass thereby via medicine transfer unit 355 to second medicine discharge point 380.
Medicine is transferred from medicine transfer unit 355 into medicine transfer container 370, and a weight of the medicine is determined via weight detecting device 395. If the measured weight is less than a given or desired dose, and if medicine is still on medicine transfer unit 355 (i.e., has not been fully discharged), then medicine transfer unit 355 further conveys more medicine into medicine transfer container 370. On the other hand, if no medicine is on medicine transfer unit 355, then additional medicine is discharged to medicine transfer unit 355 from medicine storage container 320. The process of discharging from medicine storage container 320 to medicine transfer unit 355, and from medicine transfer unit 355 to medicine transfer container 370 continues until at least a dose of medicine is contained in medicine transfer container 370. That is, medicine transfer container 370 may include an exact or desired dose, or may include an amount of medicine that is in excess of an exact dose.
If an exact dose is present in medicine transfer container 370, then dispenser 102 operates to convey medicine transfer container 370 to first medicine discharge point 350 via medicine container transfer unit 345, any remaining medicine on medicine transfer unit 355 is discharged back into medicine storage container 320 at second medicine discharge point 380, and the medicine in medicine transfer container 370 is discharged into dispensed medicine container 365 that is positioned at second medicine discharge point 380.
On the other hand, in one example medicine transfer container 370 may include an amount of medicine that is in excess of an exact dose. In such an example, medicine transfer container 370 is thereby conveyed to first medicine discharge point 350 and operations described above are repeated. That is, medicine container transfer unit 345 discharges medicine from medicine transfer container 370 onto medicine transfer unit 355, and medicine transfer container 375 is conveyed via carousel 310 to second medicine discharge point 380. Medicine discharged from medicine transfer container 370 to medicine transfer unit 355 is thereby conveyed to medicine transfer container 375 until at least the exact dose is present in medicine transfer container 375. And, again, if medicine transfer container 375 includes medicine equal to the dose, then the medicine in medicine transfer container 375 is discharged into dispensed medicine container 365, and any excess medicine on medicine transfer unit 355 is returned to medicine storage container 320.
The aforementioned steps continue until a dose of medicine is contained within dispensed medicine container 365, and any additional medicine is returned to medicine storage container 320. In such fashion, dispenser 102 includes a feedback mechanism, ensuring a proper dose, and only a proper dose, is contained in dispensed medicine container 365. That is, feedback is provided in the form of a weight of pills or capsules, corresponding to a dose, measured via weight detecting device 395. Dispenser 102 is caused to operate using such feedback to ensure that a correct dose is provided in dispensed medicine container 365.
Referring now to FIG. 12, a flow diagram of another exemplary process 1200 for operating the dispensing unit 102, which may incorporate the sub-assembly 1100, is illustrated. Process 1200 may include operations that may be part of program 110, stored on memory 108, and/or executed by processor 106. Process 1200 may take many different forms and include multiple and/or alternate steps. While an exemplary process is shown, the exemplary steps illustrated are not intended to be limiting. Indeed, additional or alternative steps and/or implementations may be used. In addition, for purposes of process 1200, the first medicine container transfer unit 330 is referred to as the carousel, and the second medicine container transfer unit 345 is referred to as the robot. However, it should be appreciated that any medicine container transfer unit 330, 345 for performing the respective step(s) is contemplated, and that the use of the terms carousel and robot are not intended to be limiting.
Process 1200 may begin at block 1202 at which the carousel 310 may transfer a medicine storage container 320 to the loading point 340 of robot 345.
At block 1204, robot 345 may transfer the medicine storage container 320 to a first medicine discharge point 350 above the conveyor 1105.
At block 1206, robot 345 may rotate the medicine storage container 320 in a controlled manner to pour medicine from the medicine storage container 320 onto the conveyor 1105, which may be stationary or moving.
At block 1208, at least one sensor 1110 may detect medicine discharged on the conveyor 1105.
At block 1210, robot 345 may stop pouring medicine storage container 320 when medicine on the conveyor 1105 is equal to or greater than a predefined quantity. This may be determined based on feedback from sensor 1110 or other means. Robot 345 may then return the medicine storage container 320 to carousel 310.
At block 1212, the carousel 310 may transfer a first medicine transfer container 375, to the second medicine discharge point 380.
At block 1214, the conveyor 1105 may move to discharge medicine from conveyor 1105 into the first medicine transfer container 375.
At block 1216, a sensor 1115 and/or scale 395 under the first medicine transfer container 375 may detect a quantity of medicine discharged into the first medicine transfer container 375.
At block 1218, the conveyor 1105 is stopped based on feedback from the sensor 1115 and/or scale 395 that the quantity of medicine inside the first medicine transfer container 375 is equal to or greater than the required dosage, or the medicine left on the conveyor 1105 is equal to the required dosage.
At block 1220, the processor 106 may determine if the medicine on the conveyor 1105 equals the required dosage. If so, carousel 310 may transfer the dispensed medicine container 365 to the second medicine discharge point 380, and the conveyor 1105 may discharge all of the medicine on it into the dispensed medicine container 365. Carousel 310, robot 345, and conveyor 355 may then work together to discharge all medicines inside the first medicine transfer container 375 back into the medicine storage container 320. Process 1200 may then end.
At block 1222, carousel 310 may transfer medicine storage container 320 to the second medicine discharge point 380, and conveyor 1105 may begin to discharge all remaining medicine on conveyor 1105 into the medicine storage container 320.
At block 1224, the processor 106 may determine if the medicine inside the first medicine transfer container 375 is equal to the required dosage. If so, carousel 310 may transfer the dispensed medicine container 365 to the second medicine discharge point 380. Carousel 310, robot 345, and conveyor 355 may then work together to discharge all medicines inside the first medicine transfer container 375, 375 into the dispensed medicine container 365. Process 1200 may then end.
At block 1226, the processor 106 may determine if the medicine inside the first medicine transfer container 375 is greater than the required dosage. If so, carousel 310 may transfer the first medicine transfer container 375 to the first medicine discharge point 350, and transfer the second medicine transfer container 370 to the second medicine discharge point 380. Blocks 1202 through 1224 may then be repeated with the medicine transfer containers 375 and 370 until the required dosage is dispensed into the dispensed medicine container 365, and all extra medicine, e.g., in the medicine transfer containers 375, 370 and/or on the conveyor 1105, is returned to the medicine storage container 320.
Process 1200 may be repeated for the next medicine when required.
In embodiments, scale(s) 395, for example, in each weighing station or storage nests associated with each container, may check quantity of medicine inside each container involved in process 1400, e.g., the medicine storage container 320, the medicine transfer containers 370, 375, and the dispensed medicine container 365.
In general, process 1200 may be a closed feedback loop process with stable and fast convergent iterations. In addition, the processor 106 may communicate with, i.e., send commands to, receive data from, and the like, to various components of the dispensing unit 102 and/or system 500 to perform process 1200, and may decide the best way to distribute the medicine among medicine storage container 320, the medicine transfer containers 370, 375, and the dispensed medicine container 365 based on process 1200.

Sub-assembly 1300 includes weight checking station 360, a calibration and verification device 382 to automatically calibrate weight detecting devices, dispensed medicine container 365, and medicine transfer container 370 and 375. Medicine storage container 320 is positioned on carousel 310.
FIG. 13A is an illustration of exemplary sub-system 1300, and FIG. 13B of the exemplary system of FIG. 13A shows end of arm tool 1310 at medicine discharge position 1325. Medicine storage container 320 may include original medicine container 390, medicine container identification unit 385, weight detecting device 395, and medicine container storage nest 335. Weight detecting device 395 and medicine container storage nest 335 may be integrated together. Weight detecting device 395 and medicine container storage nest 335 may also be part of carousel 310. Weight detecting device 395 may be a scale, a load cell, or other device for measuring weight, according to the disclosure. Weight detecting device 395 and medicine container storage nest 335 are positioned about carousel 310 at each of the illustrated locations. Medicine container identification unit 385 may include identification information particular to a given medicine, and may also identify an amount of medicine that may constitute a single patient dose particular to a given user of dispenser 102.
Referring still to FIG. 13A, medicine storage container 320 may be loaded into dispenser 102 from medicine container loading station 325, and medicine storage container 320 is transferred to medicine container loading point 340 by medicine container transfer unit 330. Medicine storage container 320 may include medicine in the form of a pill or a capsule, as examples, and a dose of medicine for a user may include one or more of the pills or capsules. Medicine container transfer unit 330 is illustrated as having carousel 310, but may instead include a conveyor, a robot, or any device that can move medicine storage container 320 from one position to another, and discharge medicine from medicine storage container 320.
Medicine transfer unit 355 moves medicine from one position to another, accepts medicine from medicine storage container 320, and medicine transfer unit 355 also discharges medicine into medicine storage container 320 or any container when positioned at medicine discharge point 380. Medicine transfer unit 355 may have a linear moving surface such as a walking beam, a conveyor, or a rotating surface such as a rotating disc or other shape, and includes in the illustrated example conveyer 1305.
In operation, as shown in FIGS. 13A and 13B, dispenser 102 moves, via carousel 310, medicine storage container 320 to loading point 312, and loading point 312 is proximate medicine container transfer unit 345. Medicine container transfer unit 345 engages with medicine storage container 320 by attaching thereto, and moving medicine storage container 320 vertically to first medicine discharge point 350. Medicine storage container 320 is, in one example, a medicine storage container which may have an amount of medicine that is in excess of a dose, or an amount of medicine that is desired to be distributed into dispensed medicine container 365. Medicine container transfer unit 345 turns medicine storage container 320 such that a predetermined amount of medicine spills or otherwise pours from medicine storage container 320 onto medicine transfer unit 355. Carousel 310 rotates to move medicine transfer container 370 to second medicine discharge point 380. When medicine transfer container 370 is positioned at medicine discharge point 380, and when medicine has been discharged onto medicine transfer unit 355, medicine transfer unit 355 thereby conveys the discharged medicine from medicine transfer unit 355 into medicine transfer container 370 until at least a second predetermined amount of medicine is contained in medicine transfer container 370, as determined by weight detecting device 395 and medicine container storage nest 335, which weigh and transmit weight information to for instance a controller of dispenser 102.
Medicine transfer unit 355 includes robot 1345 and conveyor 1305, and sensors 1110 and 1115, which monitor medicine positioned on medicine transfer unit 355 and on conveyor 1305. Sensors 1110, 1115 may be optical sensors that are coupled, electrically or optically as examples, to processor 106. As such, processor 106 monitors an amount of medicine positioned on medicine transfer unit 355 via sensors 1110, 1115. Sensors 1110 and 1115 detect the presence of pills or capsules as they pass thereby via medicine transfer unit 355 to second medicine discharge point 380. In addition, robot 1345 includes end of arm tool 1310 having vacuum head 1315 that may attach via a vacuum, controlled by processor 106, to individual pills or capsules passing along medicine transfer unit 355. Accordingly, in this example, pills or capsules may be not only conveyed by conveyor 1305 to medicine transfer container 370 or medicine transfer container 375 when positioned at medicine discharge point 380, but also conveyed by robot 1345 to medicine transfer container 370 or 375 when positioned at medicine discharge point 380. Pills or capsules may also be conveyed by robot 1345 to medicine transfer container 370 or 375 positioned at position 1320. Pills or capsules may also be conveyed by robot 1345 from medicine transfer containers 370 or 375 at discharge point 380 or 1320 back to the medicine transfer unit 355. Both methods may be used concurrently or separately. Thus, overall efficiency or movement of pills or capsules may be improved by having an ability to move pills or capsules to and/or from two locations simultaneously.
Medicine is transferred from medicine transfer unit 355 into medicine transfer container 370, and a weight of the medicine is determined via weight detecting device 395. If the measured weight is less than a given or desired dose, and if medicine is still on medicine transfer unit 355 (i.e., has not been fully discharged), then medicine transfer unit 355 further conveys more medicine into medicine transfer container 370. On the other hand, if no medicine is on medicine transfer unit 355, then additional medicine is discharged to medicine transfer unit 355 from medicine storage container 320. The process of discharging from medicine storage container 320 to medicine transfer unit 355, and from medicine transfer unit 355 to medicine transfer container 370 continues until at least a dose of medicine is contained in medicine transfer container 370. That is, medicine transfer container 370 may include an exact or desired dose, or may include an amount of medicine that is in excess of an exact dose.
If an exact dose is present in medicine transfer container 370, then dispenser 102 operates to convey medicine transfer container 370 to first medicine discharge point 350 via medicine container transfer unit 345, any remaining medicine on medicine transfer unit 355 is discharged back into medicine storage container 320 at second medicine discharge point 380, and the medicine in medicine transfer container 370 is discharged into dispensed medicine container 365 that is positioned at second medicine discharge point 380.
On the other hand, in one example medicine transfer container 370 may include an amount of medicine that is in excess of an exact dose. In such an example, medicine transfer container 370 is thereby conveyed to first medicine discharge point 350 and operations described above are repeated. That is, medicine container transfer unit 345 discharges medicine from medicine transfer container 370 onto medicine transfer unit 355, and medicine transfer container 375 is conveyed via carousel 310 to second medicine discharge point 380. Medicine discharged from medicine transfer container 370 to medicine transfer unit 355 is thereby conveyed to medicine transfer container 375 until at least the exact dose is present in medicine transfer container 375. And, again, if medicine transfer container 375 includes medicine equal to the dose, then the medicine in medicine transfer container 375 is discharged into dispensed medicine container 365, and any excess medicine on medicine transfer unit 355 is returned to medicine storage container 320.
The aforementioned steps continue until a dose of medicine is contained within dispensed medicine container 365, and any additional medicine is returned to medicine storage container 320. In such fashion, dispenser 102 includes a feedback mechanism, ensuring a proper dose, and only a proper dose, is contained in dispensed medicine container 365. That is, feedback is provided in the form of a weight of pills or capsules, corresponding to a dose, measured via weight detecting device 395. Dispenser 102 is caused to operate using such feedback to ensure that a correct dose is provided in dispensed medicine container 365. However, in the illustrated example, medicine, in this example, may be conveyed to and from medicine transfer container 370 or medicine transfer container 375 positioned at discharge position 1320 and 380, allowing simultaneous iterations using two conveying methods on two containers in both directions, which may allow convergence to a final dose, and movement of medicine to and from medicine transfer unit 355 via a second path (i.e., via vacuum head 1315, for discharge position 380 and for a container positioned at discharge position 1320).
Referring now to FIG. 14, a flow diagram of another exemplary process 1400 for operating the dispensing unit 102, which may incorporate the sub-assembly 1300, is illustrated. Process 1400 may include operations that may be part of program 110, stored on memory 108, and/or executed by processor 106. Process 1400 may take many different forms and include multiple and/or alternate steps. While an exemplary process is shown, the exemplary steps illustrated are not intended to be limiting. Indeed, additional or alternative steps and/or implementations may be used. In addition, for purposes of process 1400, the first medicine container transfer unit 330 is referred to as the carousel, and the second medicine container transfer unit 345 is referred to as the robot. However, it should be appreciated that any medicine container transfer unit 330, 345 for performing the respective step(s) is contemplated, and that the use of the terms carousel and robot are not intended to be limiting.
Blocks 1402 through 1410 may be the same or similar as blocks 1202 through 1210 of process 1200. Process 1400 may begin to diverge from process 1200 at block 1412 at which the carousel 310 may transfer a medicine transfer container 370, 375 to a medicine discharge point 1320 (as opposed to discharge point 380).
At block 1414, conveyor 1105 may vibrate to spread the medicine thereon out evenly.
At block 1416, conveyor 1105 may move forward until the sensor 1115 detects medicine, after which conveyor 1105 may stop.
At block 1418, robot 1345 may move forward from a home position 1010 until sensor 1030 detects medicine, after which robot 1345 may stop.
At block 1420, vacuum head 1315 may descend to pick up the medicine and then vacuum head 1315 may return to its original position.
At block 1422, robot 1345 may move forward to discharge the medicine on the vacuum head 1315 into the medicine transfer container 370, 375 at medicine discharge point 1320. Robot 1345 may also discharge the medicine on the vacuum head 1315 into the medicine transfer container 370, 375 at medicine discharge point 380 (not shown). Robot 1345 may also pick up medicine from medicine transfer containers 370,375 at medicine discharge point 380 or 1320 and discharge onto the medicine transfer unit 355.
At block 1424, processor 106 may determine if the medicine in the medicine transfer container 370, 375 has reached the required dosage. If it has, then process 1400 may proceed to block 1426. If it has not, and there is still medicine left along the pathway of the motion of robot 1345, then process 1400 may repeat blocks 1416 to 1422 until the required dosage has been reached, after which process 1400 may proceed to block 1426.
At block 1426, carousel 310 may transfer the medicine storage container 320 to the medicine discharge point 380, and conveyor 1105 may move forward to discharge all remaining medicine on the conveyor 1105 into the medicine storage container 320. Process 1400 may then proceed to block 1430.
At block 1428, processor 106 may determine if any medicine remains on the conveyor 1105. If not, and the medicine inside the medicine transfer container 370, 375 is still less than required dosage, blocks 1404 through 1430 may be repeated.
At block 1430, all the medicine inside of the medicine transfer container 370, 375 may be discharged into the dispensed medicine container 365.
Process 1400 may be repeated for the next medicine when required or process 1400 may end.
In embodiments, scale(s) 395, for example, in each weighing station or storage nests associated with each container, may check quantity of medicine inside each container involved in process 1400, e.g., the medicine storage container 320, the medicine transfer containers 370, 375, and the dispensed medicine container 365.
In general, process 1400 may be a closed feedback loop process with stable and fast convergent iterations. In addition, the processor 106 may communicate with, i.e., send commands to, receive data from, and the like, to various components of the dispensing unit 102 and/or system 500 to perform process 1400, and may decide the best way to distribute the medicine among medicine storage container 320, the medicine transfer containers 370, 375, and the dispensed medicine container 365 based on process 1400.
FIG. 15A illustrates an exemplary sub-assembly 1500 of dispenser 102 with a conveyor, a robot, a vacuum head (mounted on the same robot or a different robot), a vision system, and a carousel. In this example medicine container transfer unit 330 includes carousel 310, medicine container transfer unit 345 includes a robot with end of arm tool, medicine transfer unit 355 includes conveyor 1305, two sensors 1110 (not visible) and 1115, robot 1345 with end of arm tool 1310, sensor 1330, vacuum head 1315, and a machine vision system 1505 coupled to processor 106 and configured to output a visual location and images of items, such pills or capsules, of dispenser 102. Robot 345 and robot 1345 may be two different robots, or two different parts of the same one robot.
FIG. 15B shows end of arm tool 1310 at medicine discharge position 1325 to discharge medicine into the medicine storage container at the medicine container transfer unit 330 discharge position 1320. End of arm tool 1310 may also discharge medicine into medicine storage container at medicine container transfer unit 330 discharge position 380 (not shown).
FIG. 15A illustrates an exemplary sub-assembly 1500 of the disclosed system. Sub-assembly 1500 includes medicine container transfer unit 330 having carousel 310, medicine container transfer unit 345 includes a robot with end of arm tool. Medicine transfer unit 355 includes a robot or conveyor 1305, sensors 1110 (not visible) and 1115, robot 1345 having an end of arm tool (EOAT) 1310, a sensor 1330, and a vacuum head 1315. Medicine container transfer unit 345 and robot 1345 may be two different robots, or two different parts of the same one robot. FIG. 15B is a view of the example of FIG. 15A, showing end of arm tool 1310 at medicine discharge position 1325 to discharge medicine into medicine storage container at medicine container transfer unit 330 discharge position 1320. The end of arm tool 1310 may also discharge medicine into medicine storage container at medicine container transfer unit 330 discharge position 380 (not shown).
Sub-assembly 1500 is a view of inside elements of dispenser 102 and includes carousel 310. Sub-assembly 1500 includes loading station or medicine container loading station 325, first medicine container transfer unit 330, and medicine container storage nest 335. Medicine container loading point 340 is proximate second medicine container transfer unit 345. First medicine discharge point 350 includes, in the illustrated example, medicine transfer unit 355 that may include robot 1345 and conveyer 1305 for transporting or otherwise conveying medicine from medicine container transfer unit 345 to second medicine discharge point 380, and may include sensors 1110 (not visible) and 1115. Sub-assembly 1500 includes weight checking station 360, a calibration and verification device 382 to automatically calibrate weight detecting devices, dispensed medicine container 365, and medicine transfer container 370 and 375. Medicine storage container 320 is positioned on carousel 310.
FIG. 15A is an illustration of medicine storage container 320 as positioned proximate medicine container transfer unit 345, and FIG. 15B of the exemplary system of FIG. 15A shows end of arm tool 1310 at medicine discharge position 1325. Medicine storage container 320 may include original medicine container 390, medicine container identification unit 385, weight detecting device 395, and medicine container storage nest 335. Weight detecting device 395 and medicine container storage nest 335 may be integrated together. Weight detecting device 395 and medicine container storage nest 335 may also be part of carousel 310. Weight detecting device 395 may be a scale, a load cell, or other device for measuring weight, according to the disclosure. Weight detecting device 395 and medicine container storage nest 335 are positioned about carousel 310 at each of the illustrated locations. Medicine container identification unit 385 may include identification information particular to a given medicine, and may also identify an amount of medicine that may constitute a single patient dose particular to a given user of dispenser 102.
Referring still to FIG. 15A, medicine storage container 320 may be loaded into dispenser 102 from MCLS 325, and medicine storage container 320 is transferred to MCLP 340 by medicine container transfer unit 330. Medicine storage container 320 may include medicine in the form of a pill or a capsule, as examples, and a dose of medicine for a user may include one or more of the pills or capsules. Medicine container transfer unit 330 is illustrated as having carousel 310, but may instead include a conveyor, a robot, or any device that can move medicine storage container 320 from one position to another, and discharge medicine from medicine storage container 320.
Medicine transfer unit 355 moves medicine from one position to another, accepts medicine from medicine storage container 320, and medicine transfer unit 355 also discharges medicine into medicine storage container 320 or any container when positioned at medicine discharge point 380. Medicine transfer unit 355 may have a linear moving surface such as a walking beam, a conveyor, or a rotating surface such as a rotating disc or other shape, and includes in the illustrated example conveyer 1305.
In operation, as shown in FIGS. 15A and 15B, dispenser 102 moves, via carousel 310, medicine storage container 320 to loading point 312, and loading point 312 is proximate medicine container transfer unit 345. Medicine container transfer unit 345 engages with medicine storage container 320 by attaching thereto, and moving medicine storage container 320 vertically to first medicine discharge point 350. Medicine storage container 320 is, in one example, a medicine storage container which may have an amount of medicine that is in excess of a dose, or an amount of medicine that is desired to be distributed into dispensed medicine container 365. Medicine container transfer unit 345 turns medicine storage container 320 such that a predetermined amount of medicine spills or otherwise pours from medicine storage container 320 onto medicine transfer unit 355. Carousel 310 rotates to move medicine transfer container 370 to second medicine discharge point 380. When medicine transfer container 370 is positioned at medicine discharge point 380, and when medicine has been discharged onto medicine transfer unit 355, medicine transfer unit 355 thereby conveys the discharged medicine from medicine transfer unit 355 into medicine transfer container 370 until at least a second predetermined amount of medicine is contained in medicine transfer container 370, as determined by weight detecting device 395 and MCSN 335, which weigh and transmit weight information to for instance a controller of dispenser 102.
Medicine transfer unit 355 includes robot 1345 and conveyor 1305, and sensors 1110 and 1115, which monitor medicine positioned on medicine transfer unit 355 and on conveyor 1305. Sensors 1110, 1115 may be optical sensors that are coupled, electrically or optically as examples, to processor 106. As such, processor 106 monitors an amount of medicine positioned on medicine transfer unit 355 via sensors 1110, 1115. Sensors 1110 and 1115 detect the presence of pills or capsules as they pass thereby via medicine transfer unit 355 to second medicine discharge point 380. In addition, robot 1345 includes end of arm tool 1310 having vacuum head 1315 that may attach via a vacuum, controlled by processor 106, to individual pills or capsules passing along medicine transfer unit 355. Accordingly, in this example, pills or capsules may be not only conveyed by conveyor 1305 to medicine transfer container 370 or medicine transfer container 375 when positioned at medicine discharge point 380, but also conveyed by robot 1345 to medicine transfer container 370 or 375 when positioned at medicine discharge point 380. Pills or capsules may also be conveyed by robot 1345 to medicine transfer container 370 or 375 positioned at position 1320. Pills or capsules may also be conveyed by robot 1345 from medicine transfer containers 370 or 375 at discharge point 380 or 1320 back to the medicine transfer unit 355. Both methods may be used concurrently or separately. Thus, overall efficiency or movement of pills or capsules may be improved by having an ability to move pills or capsules to two locations simultaneously.
Medicine is transferred from medicine transfer unit 355 into medicine transfer container 370, and a weight of the medicine is determined via weight detecting device 395. If the measured weight is less than a given or desired dose, and if medicine is still on medicine transfer unit 355 (i.e., has not been fully discharged), then medicine transfer unit 355 further conveys more medicine into medicine transfer container 370. On the other hand, if no medicine is on medicine transfer unit 355, then additional medicine is discharged to medicine transfer unit 355 from medicine storage container 320. The process of discharging from medicine storage container 320 to medicine transfer unit 355, and from medicine transfer unit 355 to medicine transfer container 370 continues until at least a dose of medicine is contained in medicine transfer container 370. That is, medicine transfer container 370 may include an exact or desired dose, or may include an amount of medicine that is in excess of an exact dose.
If an exact dose is present in medicine transfer container 370, then dispenser 102 operates to convey medicine transfer container 370 to first medicine discharge point 350 via medicine container transfer unit 345, any remaining medicine on medicine transfer unit 355 is discharged back into medicine storage container 320 at second medicine discharge point 380, and the medicine in medicine transfer container 370 is discharged into dispensed medicine container 365 that is positioned at second medicine discharge point 380.
On the other hand, in one example medicine transfer container 370 may include an amount of medicine that is in excess of an exact dose. In such an example, medicine transfer container 370 is thereby conveyed to first medicine discharge point 350 and operations described above are repeated. That is, medicine container transfer unit 345 discharges medicine from medicine transfer container 370 onto medicine transfer unit 355, and medicine transfer container 375 is conveyed via carousel 310 to second medicine discharge point 380. Medicine discharged from medicine transfer container 370 to medicine transfer unit 355 is thereby conveyed to medicine transfer container 375 until at least the exact dose is present in medicine transfer container 375. And, again, if medicine transfer container 375 includes medicine equal to the dose, then the medicine in medicine transfer container 375 is discharged into dispensed medicine container 365, and any excess medicine on medicine transfer unit 355 is returned to medicine storage container 320.
The aforementioned steps continue until a dose of medicine is contained within dispensed medicine container 365, and any additional medicine is returned to medicine storage container 320. In such fashion, dispenser 102 includes a feedback mechanism, ensuring a proper dose, and only a proper dose, is contained in dispensed medicine container 365. That is, feedback is provided in the form of a weight of pills or capsules, corresponding to a dose, measured via weight detecting device 395. Dispenser 102 is caused to operate using such feedback to ensure that a correct dose is provided in dispensed medicine container 365. However, in the illustrated example, medicine, in this example, may be conveyed to and from medicine transfer container 370 or medicine transfer container 375 positioned at discharge position 1320 and 380 in both directions, allowing simultaneous or sequential iterations using two containers and two conveying methods in both directions, which may allow convergence to a final dose, and movement of any additional medicine from medicine transfer unit 355 via a second path (i.e., via vacuum head 1315, for containers positioned at position 1320 and 380). Additionally, vision system 1505 provides yet additional functionality, in that vision system 1505 may convey an image of pills or capsules passing along medicine transfer unit 355, providing a visual representation of the pills or capsules, and an additional method of identifying the movement thereof into medicine transfer container 370 and/or medicine transfer container 375. Process 106 may compare these images with images stored in database 122 to make sure correct medicine is dispensed.
Referring now to FIG. 16, a flow diagram of another exemplary process 1600 for operating the dispensing unit 102, which may incorporate the sub-assembly 1500, is illustrated. Process 1600 may include operations that may be part of program 110, stored on memory 108, and/or executed by processor 106. Process 1600 may take many different forms and include multiple and/or alternate steps. While an exemplary process is shown, the exemplary steps illustrated are not intended to be limiting. Indeed, additional or alternative steps and/or implementations may be used. In addition, for purposes of process 1600, the first medicine container transfer unit 330 is referred to as the carousel, and the second medicine container transfer unit 345 is referred to as the robot. However, it should be appreciated that any medicine container transfer unit 330, 345 for performing the respective step(s) is contemplated, and that the use of the terms carousel and robot are not intended to be limiting.
Process 1600 generally may be the same as or similar to process 1400, but may differ in the incorporation of the vision system 1505. For example, blocks 1602 through 1610 may correspond to blocks 1402 through 1414 of process 1400. Process 1600 may begin to diverge from process 1400 at block 1616 at which the conveyor 1105 may move forward, and the vision system 1505 may take pictures of the area of the conveyor 1105 and process the images. Conveyor 1105 may stop when the sensor 1115 detects medicine or the vision system 1505 gives instructions.
At block 1618, the vision system 1505 may process the images to determine correct medicine is dispensed and locations of the medicine on the conveyor 1105 under robot 1345.
At block 1620, the processor 106 and the vision system 1505 may work together to guide conveyor 1105 and robot 1345 movements to align vacuum head 1315 and a piece of medicine to be picked up.
The remaining blocks 1622 through 1632 may correspond with blocks 1420 through 1430 of process 1400.
Process 1600 may be repeated for the next medicine when required or the process 1600 may end.
In embodiments, scale(s) 395, for example, in each weighing station or storage nests associated with each container, may check quantity of medicine inside each container involved in process 1600, e.g., the medicine storage container 320, the medicine transfer containers 370, 375, and the dispensed medicine container 365.
In general, process 1600 may be a closed feedback loop process with stable and fast convergent iterations. In addition, the processor 106 may communicate with, i.e., send commands to, receive data from, and the like, to various components of the dispensing unit 102 and/or system 500 to perform process 1600, and may decide the best way to distribute the medicine among medicine storage container 320, the medicine transfer containers 370, 375, and the dispensed medicine container 365 based on process 1600.
FIG. 17A illustrates an exemplary sub-assembly 1700 of the disclosed dispenser 102. FIG. 17B illustrates the exemplary system of FIG. 17A during operation. FIG. 17C illustrates a top view of the exemplary system of FIGS. 17A and 17B.
FIG. 17A is an example of dispenser 102 having a rotating table, a robot, and a carousel. In this example medicine container transfer unit 330 includes carousel 310, medicine container transfer unit 345 includes a rotating table 1705 and sensors 1710 and 1720. FIG. 17B shows medicine storage container 320 transferred to medicine discharge point 350 by medicine container transfer unit 345 to discharge medicine from the medicine storage container 320 to rotating table 1705. Sensors 1710 and 1720 monitor the medicine on table 1705.
FIG. 17A illustrates the disclosed dispenser 102 having rotating table 1705 and sensors 1710 and 1720. In this example medicine container transfer unit 330 includes carousel 310, and medicine container transfer unit 345 includes table 1705 on which pills or capsules may be placed, such that they may roll or otherwise move in a generally circular fashion to discharge position 1320.
FIG. 17B is a view of sub-assembly as shown in FIG. 17A, showing medicine storage container 320 transferred to first medicine discharge point 350 by medicine container transfer unit 345 to discharge medicine from medicine storage container 320 to table 1705.
FIG. 17A illustrates an exemplary sub-assembly 1700 illustrating the disclosed system or dispenser. Sub-assembly 1700 is a view of inside elements of dispenser 102 and includes carousel 310. Sub-assembly 1700 includes first medicine container transfer unit 330, and medicine container storage nest 335. Medicine container loading point 340 is proximate second medicine container transfer unit 345. Medicine container transfer unit 345 may include table 1705 and may include sensors 1710 and 1720. Sub-assembly 1700 includes weight checking station 360, a calibration and verification device 382 to automatically calibrate weight detecting devices, dispensed medicine container 365, and medicine transfer container 370 and 375. Medicine storage container 320 is positioned on carousel 310.
In operation, carousel 310 moves medicine storage container 320 to loading point 312, and loading point 312 is proximate medicine container transfer unit 345. Medicine container transfer unit 345 engages with medicine storage container 320 by attaching thereto, and moves medicine storage container 320 to first medicine discharge point 350. Medicine storage container 320 is, in one example, a medicine storage container which may have an amount of medicine that is in excess of a dose, or an amount of medicine that is desired to be distributed into dispensed medicine container 365. Medicine container transfer unit 345 turns medicine storage container 320 such that a predetermined amount of medicine spills or otherwise pours from medicine storage container 320 onto rotating table 1705, as illustrated in FIG. 17B. Rotating table 1705 is configured to rotate or jostle back and forth, causing items such as pills or capsules thereon to jostle or vibrate, such that the items pass about a circumference of rotating table 1705 and in a rotational direction 1730 to a chute 1725.
When medicine transfer container 370 is positioned at discharge position 1320, and when medicine has been discharged onto rotating table 1705, rotating table 1705 thereby conveys the discharged medicine from rotating table 1705 into medicine transfer container 370 positioned at discharge position 1320, until at least a second predetermined amount of medicine is contained in medicine transfer container 370, as determined by weight detecting device 395 and medicine container storage nest 335, which weigh and transmit weight information to for instance a controller of dispenser 102.
Medicine is transferred from rotating table 1705 into medicine transfer container 370, and a weight of the medicine is determined via weight detecting device 395. If the measured weight is less than a given or desired dose, and if medicine is still on rotating table 1705 (i.e., has not been fully discharged), then rotating table 1705 further conveys more medicine into medicine transfer container 370. On the other hand, if no medicine is on rotating table 1705, then additional medicine is discharged to rotating table 1705 from medicine storage container 320. The process of discharging from medicine storage container 320 to rotating table 1705, and from rotating table 1705 to medicine transfer container 370 continues until at least a dose of medicine is contained in medicine transfer container 370. That is, medicine transfer container 370 may include an exact or desired dose, or may include an amount of medicine that is in excess of an exact dose.
If an exact dose is present in medicine transfer container 370, then dispenser 102 operates to convey medicine transfer container 370 to discharge position 1320 via medicine container transfer unit 345, any remaining medicine on rotating table 1705 is discharged back into medicine storage container 320, and the medicine in medicine transfer container 370 is discharged into dispensed medicine container 365.
The aforementioned steps continue until a dose of medicine is contained within dispensed medicine container 365, and any additional medicine is returned to medicine storage container 320. In such fashion, dispenser 102 includes a feedback mechanism, ensuring a proper dose, and only a proper dose, is contained in dispensed medicine container 365. That is, feedback is provided in the form of a weight of pills or capsules, corresponding to a dose, measured via weight detecting device 395. Dispenser 102 is caused to operate using such feedback to ensure that a correct dose is provided in dispensed medicine container 365.
Referring now to FIG. 18, a flow diagram of another exemplary process 1800 for operating the dispensing unit 102, which may incorporate the sub-assembly 1700, is illustrated. Process 1800 may include operations that may be part of program 110, stored on memory 108, and/or executed by processor 106.
