(10) While the invention is amenable to various modifications and alternative forms, specifics thereof have been shown by way of example in the drawings and will be described in detail. It should be understood, however, that the intention is not to limit the invention to the particular embodiments described. On the contrary, the invention is to cover all modifications, equivalents, and alternatives falling within the spirit and scope of the invention as defined by the appended claims.
DETAILED DESCRIPTION OF THE INVENTION
(11) Referring generally to
(12) Each embodiment of the dispensing system 100 can comprise a controller 105 or like electronic hardware that can include a microprocessor 105a and physical memory coupled to the microprocessor 105a (e.g.,
(13) Referring to
(14) The medication reservoir section 106 can include one or more medication reservoirs 108 and a central drive and axis 110. The central drive 110 is operatively connectable and registerable with a motor of the dispensing section 120 such that the reservoirs 108 are capable of selectively rotating about the dispensing section 120. Upon rotation, the reservoirs 108 will individually align with the fill port 104 for receiving medication into one or more of the reservoirs 108, and then moving from a position under the fill port 104 on top of the device to a position above a dispensing and/or encapsulation chamber. The medication within the aligned reservoir 108 is then dispensable through the dispensing assembly 112.
(15) With such embodiments, the reservoirs 108 are large enough for each to contain 90 to 120 pills or capsules. When in the fill position, the top of a reservoir 108 is open and centered beneath the fill hatch 104. Capsules or pills P are easily poured into the reservoir 108 via the hatch 104. After the first aligned reservoir 108 is filled, the group of medication reservoirs 108 then rotates around the axis 110 such that the next empty reservoir 108 moves into the fill position in alignment with the hatch 104. The filling and identification process can be repeated for each included reservoir 108. With other embodiments, the reservoirs 108 are sized and shaped to hold a single pod that contains medication in a solid, liquid or powder form and may not include a fill port.
(16) Before, during, and after the filling process is complete, software within the processor 105a allows the patient's doctor, or other medical personnel, to monitor and control the insertion of medications and how those medications are dispensed. As described further herein, the doctor's instructions can be delivered to the dispensing device via a cloud computing device (e.g., Internet connected), a USB thumb drive, or a medical personnel device in operative communication with the system 100, controller 105, and processor 105a. The provided dispensing data and instructions enable the system 100 to deliver medication in any specified combination, timing, or other pattern. The system software also allows the doctor to personalize or optimize treatment by conducting trials or treatment regimens that require medications to be dispensed according to predetermined protocols. The unique software and medication delivery mechanism gives doctors a practical tool to deliver optimal care when the best treatment is known, and dynamically when the best treatment is not known.
(17) Referring to
(18) After the medication has been covered, the cylinder 130 rotates, and the medication drops through an opening into a chamber mechanism 136 where the newly formed capsule shells are heat sealed and stamped with a bar code that can be used to identify the medication within the capsule. The medication then drops via device or element 122 and out into the patient's pill or medication cup 124. When over-encapsulation is not necessary, the medications simply funnel down through the middle section 112, bypassing the above-described mechanisms, and the pills, capsules, solution, and the like, are simply dispensed through the output 120 in their original form.
(19) In other embodiments of the system 100, the medication reservoirs 108 are configured as, or include, pods filled with medication that has not been divided or shaped into pills, capsules, or other separate dosing forms. In certain embodiments, the medication within these reservoir pods can be in a liquid, solid, or powder form. In this version of the system 100, an over-encapsulation chamber 112 would not need to be included. Instead, a precision dosing mechanism is included that measures the exact dose of each medication. The medication is then placed into a solution or form that is dispensed to the patient through the output 120.
(20) Referring to
(21) The medication reservoirs 108a of the reservoir assembly 106a can each include or define medication pods 140. The reservoirs 108a are sized and shaped to hold one or more, capsules, pills, tablets, and the like. With certain applications, the reservoirs 108a can be sized and shaped to contain a single standardized pod that contains medication in a solid, liquid or powder form. The pods 140 can be prefilled with medication and provided to the patient with the reservoir assembly 106a. In various embodiments, the pods 140 are not separable from and are integrated with, or part of, the reservoirs 108a.
(22) The pods 140 can include a funneling portion 144. Spinning rotation of the assembly 106a correspondingly aligns a reservoir 108a and a corresponding bottom outlet 108b with a top inlet 150 of the dispensing assembly 112a. As such, medication, such as one or more pills P, capsules, and the like, can drop or otherwise travel from the medication pod 140, through the bottom outlet 108b of the reservoir assembly 106a, and into the top inlet 150 of the dispensing assembly 112a, for dispensing through the dispenser 122. The assemblies 106a, 112a are adapted to snap or otherwise couple together such that the reservoir assembly 106a rotates relative to the dispensing assembly 112a. Further, the reservoir assembly 106a, or portions thereof, can be disposable in various embodiments and can be preloaded with customized drug regimens, including over-encapsulated medication, and delivered to the patient for use with the system 100.
(23) The bottom of each of the reservoirs 108a (e.g., at outlet 108b) can include a bar-code, electromagnetic code, or other identifying indicia or elements, and the dispensing assembly 112a can include a sensor, reader mechanism or device, etc. to read or sense the unique signature or identification characteristic of the individual reservoirs 108a. When the dispensing assembly 112 reads or detects the unique signature for the reservoir 108a containing the correct or desired medication, the reservoir assembly 106a is rotated into position for dispensing from that reservoir 108a. Dispensing of the medication is detected and stored. Further, dispensing data, such as the time and date the medication was dispensed, is processed and stored at the system 100 or via the cloud system. In addition, data from peripheral devices, inputted answers from the patient, and other data and information can be processed and stored as well, as detailed further herein.
(24) The bottom outlet 108b, or another portion of the assemblies 106a, 112a, can include a rotating output element 146. In certain embodiments, the rotating output element 146 can be provided with or connected to the upper assembly 106a (e.g., within the outlet 108b) such that the element 146 is above the cavity opening 150 upon registered rotation. Further, a pill P falling or otherwise traveling out of the element 146 and down through opening 151 can enter an additional or secondary rotating element 146. Such an embodiment with dual rotating elements 146 can increase the level of redundancy and safety provided, and can facilitate medication confirmation with the lower assembly 112a permitting bar code reading, or implementing other identification devices or techniques.
(25) The rotating element 146 can include a cavity opening 151. In use, as shown in
(26) The compact (e.g., cylindrical) medication dispenser system 100 of various embodiments can employ software algorithms, blood pressure measurements, and symptom assessments to determine the best blood pressure medication for an individual patient, for example. The system 100 can be prescribed by clinicians and can arrive prefilled with multiple types and dosages of medications. The system dispenses short courses of specific drugs and dosages while collecting blood pressure and symptom measurements. Treatments are compared systematically to determine which is most effective and least bothersome to the patient. The optimal drug is then continually dispensed while compliance and ongoing treatment effect are monitored.
(27) Various embodiments of the system 100, including but not limited to those of
(28) Referring to
(29) The exemplary architecture of
(30) As detailed herein, the system 100 is an interactive tool that connects a doctor in a clinic (e.g., at medical computing device 160) with a patient in their home, can interact with peripheral devices 111, can process data, prompt, and receive input at user devices 103. The system can use ethernet, Wi-Fi, cellular, or any other form of wired or wireless connectivity to receive instructions, directly or indirectly, from the medical personnel device 160. If Internet connectivity is not available, there is one or more USB ports (or other data transfer and communication ports) that facilitates the delivery of instructions—e.g., by a thumb drive, a computing device, or similar storage or data communication devices.
(31) The peripheral devices 111 can include weight scales, blood pressure monitoring devices or cuffs, wearables like a Fitbit or an Apple Watch, and a myriad of other health, measurement, and monitoring devices. In certain embodiments, communication with these distinct devices 111 and systems can be accomplished via Bluetooth connectivity. This allows input of patient measurements and data which are then transmitted to the clinic or other medical personnel for review and processing—and communication back from the medical personnel to the system 100.
(32) The system 100 also tracks medication compliance and records the effect of treatment. Each time a medication is dispensed, the medication name, dose, and time of day are processed and stored in a log or database. Periodically, the device 103 or the system 100 itself can prompt the patient to answer, via inputs, a symptom questionnaire or to make a physiologic measurement. For example, blood pressure or weight data can be received from the operatively coupled peripheral device 111, or from manually inputted data and information. The results are transmitted and stored in a database log—e.g., at the user device 103, the controller 105, the medical personnel device 160, and/or the cloud system 170.
(33) The user device 103 allows the patient to receive prompts and messages from the system 100, while also permitting the patient to input data and otherwise interact with the system 100. User devices 103 can include mobile devices such as smart phones and tablet devices, laptops, personal computers, or any other computing device capable of communicating with the system 100 (e.g., via wired or wireless connectivity).
(34) The clinician or medical personnel device 160 can be in operative communication with the system 100 and the user device 103. The clinician devices 160 can include mobile devices such as smart phones and tablet devices, laptops, personal computers, or any other computing device capable of communicating with the system 100 (e.g., via wired or wireless connectivity). Further, the clinician devices 160, and the user devices 103, can communicate with and process data and execute software code through or via the network computing system 170, such as a cloud server, in certain embodiments of the system 100.
(35) Further, the body 101, or other assemblies and sections of the system 100, can include an LCD or like display that displays text and images and facilitates touchscreen inputs. A speaker output device can be included to allow for the transmission of audible information to the patient.
(36)
(37) The reservoir assembly disc 106a can be filled with enough medication to run a treatment protocol for a fixed period of time—e.g., up to three months. All of the reservoirs 108a in the reservoir assembly disc 106a can be filled with medication, or one or more of the reservoirs 108a can be left empty. The treatment protocol and the corresponding duration for that protocol will be the determining factors. In one prescribed treatment example, the reservoir assembly disc 106a is filled for a one-month run, and only two or three reservoirs 108a include blood pressure medication or a placebo (depending on the protocol). The other reservoirs 108a (e.g., six or seven reservoirs) can be filled with the patient's other prescribed medications, such as medications for cholesterol, reflux, diabetes, etc. This inclusion of multiple distinct medications within the reservoir assembly disc 106a is facilitated by the doctor. The doctor, via the cloud system 170, can have the patient's other medication prescriptions transferred to the subject pharmacy. Accordingly, a new reservoir assembly disc 106a can be shipped to the patient every month, filled with the appropriate medication from the treatment protocol as well as refills of the patient's other medications. It is noted that the cloud system 170 and/or the personnel and company controlling and facilitating the processes described herein, can act as the pharmacy for filling and distribution of the reservoirs discs 106a and can monitor, process, and control each aspect of the processes after the initial doctor visit and prescription steps.
(38) At step 212, if this is the initial shipment and receipt of the system 100, the patient will set up the system, components, and any peripherals 111. If the patient already has at least the base dispensing section 112a of the system 100, the patient simply connects the reservoir assembly disc 106a to the dispensing section 112a for use. The patient then begins the prescribed treatment protocol through the system 100 at step 214. The system 100 receives inputs and data, controls dispensing, monitors adherence, and can provide notifications and operatively communicate data and feedback to the user device 103 as well as the cloud system 170 and the medical personnel device 160 (step 218).
(39) In those example situations where a diagnosis of hypertension is in doubt, the treatment protocol may begin with a placebo and blood pressure measurements inputted from the peripheral device 111 for two weeks to confirm the diagnosis. Otherwise, medications will be dispensed from the system 100 each day while the patient measures their blood pressure via the peripheral device 111. The patient can also input answers to a series of symptom questions at the device 103 or directly at the system 100—e.g., via a touch input device provided with the base dispensing assembly 112a. If blood pressure readings do not reach goal after an allotted time, or side effects develop, the system 100 per the protocol in place will automatically change the dose or the medication itself. The treatment change will be seamless and does not require further inputs from the patient or their doctor. The system 100 will send notification of the change in treatment and the reason for the change (e.g., poor response or side effect) to the patient's doctor. Also, when medication refills are due, the system 100 will provide the pharmacy with up-to-date details of the medications dispensed and the progression of the protocol. This will allow the pharmacy to adapt to the patient's unique spot in the protocol and, accordingly, fill and ship a new reservoir assembly disc 106a that contains the medications and dosages that are required or might be required as the treatment protocol continues. The patient will then receive the disc 106a and connect it to the base dispensing assembly 112 for another period (e.g., one month) of ongoing use. Again, the treatment of high blood pressure is provided for illustrative purposes only and is not intended to limit the various treatment protocols, medications, applications, or uses for the system 100.
(40) Referring to
(41) The software 300 also performs ongoing statistical analysis of data inputs from the patient. For example, as an N-of-1 trial proceeds, the ongoing comparisons between treatments will lead to updates of the likelihood that, in the end, there will be statistical and meaningful differences between treatments. Substantive differences between treatments will make it much more likely that an eventual difference will be found.
(42) Referring to
(43) The software and methods 400 will enable medications to be dispensed in a manner that personalizes and optimizes the treatment (such as hypertension) according to the consensus recommendations of accepted experts, boards, and panels, such as the American College of Cardiology (ACC), the American Heart Association (AHA), etc. In addition to N-of-1 protocols, the algorithms and processing of the software 400 can include sequential monotherapy, stepwise dose adjustment patterns, and other treatment protocols and techniques.
(44) As illustrated in the flow chart of
(45) At step 404, the patient characteristics will, in some cases, result in specific drug treatment requirements. Some conditions or medical histories will indicate that a certain drug be used or avoided. Also, the online portal will allow a patient's clinician to specify a strong treatment preference. For example, a clinician, for various reasons, may believe a certain blood pressure medication would be beneficial. If there is a specific drug requirement or strong clinician preference, a tailored treatment protocol can be used. Otherwise the process will proceed with a standard treatment protocol.
(46) At step 406, information entered or inputted into the software 400 (e.g., online) can include baseline blood pressure measurements. If blood pressure is greater than 20 mmHg systolic or 10 mmHG diastolic above goal, treatment will begin with combination therapy, for example.
(47) As illustrated with step 408, standard therapy utilizes the drugs shown to reduce clinical events. Consistent with the best clinical evidence to date and according to the recommendations of the ACC/AHA, the primary agents used in the treatment of hypertension include thiazide diuretics, ACE inhibitors, angiotensin receptor blockers (ARBs), and calcium channel blockers (CCBs). These drugs are used in the treatment protocols delivered by the system 100 (both standard and tailored protocols). In the initial standard and tailored protocols, low and moderate doses of each drug will be available. In the resistant hypertension protocols, high doses of these drugs will be available.
(48) Referring to step 410, combination therapy will utilize all combinations of the four drug classes noted above, except ACE inhibitors and ARBs should not be combined. Also, the underlying treatment principle is to use the lowest doses of medications needed to reach a blood pressure goal. This approach minimizes the risk of side effects as they become more likely as the doses of medication increase. Thus, the combination of two moderate doses is not used until all low/low and low/moderate combinations have been tried.
(49) Referring to step 412 and 414, tailored protocols can be the same as standard protocols, except certain drugs will be removed from the treatment algorithm if contraindicated. Also, certain drugs may be moved to the beginning of the algorithm if preferred, or to the back of the algorithm if the preference is to avoid their use if possible.
(50) Aspects of the software code of the invention, or code used with the invention, can take the form of a plugin or app, a web app, or a website interface, and can interface with various protocols or software using APIs or other means of interacting with computing software and systems.
