Patent Application
20150134108
The present disclosure relates to an apparatus with a pre-loaded cassette including a plurality of compartments in which are stored a plurality of medications. The cassettes are sealed and the apparatus is configured to extract, from each compartment, the medications according to a schedule. The present disclosure also includes a computer-based system including a computer for a service entity configured to receive prescriptions from health care providers, transmit the prescriptions to a pharmacy entity, which loads the medications in the compartments, and communicate with the apparatus.
Medication adherence, including patient adherence to medication regimens is an important aspect of any system providing medical services. Specifically, lack of medical adherence has a negative effect on outcomes and increases costs associated with providing medical services. For example, research shows that:
Several solutions have been proposed to address the problem of medical adherence with respect to medication regimens. One solution path is to provide more coordinated delivery of medications to the patient, especially since many people have prescriptions for multiple medications, each requiring different dosage regimens. For example, it is known for a pharmacy to deliver multiple medications by mail in blister-pack format. Each blister in the package contains all medications to be taken at one time. There may be two to four blisters per day. Each package will typically contain a week's worth of a patient's medications. The patient is required to burst the appropriate blister at the appropriate time, remove the pills, and take them. However, there are known problems with this approach. For example, the medication administration is ‘open loop’, that is, there is no way for a health care provider, pharmacy, or other interested party to determine of if the pills were removed from a blister at the appropriate time and taken by the patient at the appropriate time. The blister pack must be amenable to handling and shipping, for example, relatively inexpensive, light weight, and easy filled. However, such a configuration may not be an optimal configuration for a patient to use.
It is also is known to use home-based medication dispensers. For example, the patient or a designated caregiver is required to periodically pre-load the appropriate pills into provided cups, according to each pill's dosage regimen. The pre-loaded cups are then placed into the dispenser. The dispenser then releases each cup's contents at a designated time. The dispenser, being an active device, can alert the patient via audible alarm that medication is due to be taken. The dispenser can also communicate via telephone line with a remote caregiver or monitoring service. However, there are problems with the dispensers. The patient and/or caregiver must be responsible to fulfill multiple prescriptions, which may be out of synch with each other. Any pill packing errors by the patient or caregiver will not be detected by the dispenser. Any potential medication interactions will not be flagged since different prescriptions are not coordinated.

The discussions above and below directed to information 106, medications 112, and compartments 120A are applicable to information 146, medications 152, and compartments 120B. It also should be understood that apparatus 100 is not limited to the two sets of prescription information, medications, and compartments described above, and that other numbers of sets of prescription information, medications, and compartments are possible. It also should be understood that although sets of prescription information, medications, and compartments described above, the descriptions above are applicable to a single sets of prescription information, medications, and compartments.
In an example embodiment, port 126 is an opening in lid 186 of the cassette. The lid is attached to the body and is rotatable about central axis 180 using actuator 188, which can be any actuator known in the art. The lid also can be a molded plastic part and port 126 an aperture corresponding to the size and shape of one compartment 120. Thus, when lid 186 is rotated to align port/aperture 126 with a compartment, all the pills in the compartment fall out of the compartment by gravitational force into dispensing port 190. Cassette 104 can be shipped so that port/aperture 126 is locked into position corresponding to an empty reserve compartment, for example by anti-rotation feature 192. When the cassette is installed in dispensing device 102 and has been confirmed as being a correct cassette, the locking of the lid is removed and at the appropriate time, actuator 188 rotates the lid to align with the appropriate compartment 120.
In an example embodiment, dispenser 102 includes lid drive gear shaft 194, lid 186 includes hub 196, and body 177 includes hub 198. Hubs 196 and 198 enable relative rotation of the lid and body 177.
The following provides further detail regarding apparatus 100, system 200, and flow chart 300. Advantageously, service entity 204 and computer 202 are able to integrate and synchronize various prescriptions for a patient. For example, the prescriptions may originate from different health care providers who may not be in communication with each other or even aware that other medications being prescribed by other health care providers. For example, computer 202 receives prescriptions 224 and 230 and sends the prescriptions to the pharmacy entity for fulfillment. Thus, all the prescriptions for the patient are integrated by computer 202. Pharmacy entity 214 is able to preload cassette 104 with the respective dosages of the medications included in prescriptions 224 and 230 and deliver the preloaded cassette according to a schedule that can be established and adjusted as needed by the patient. Preloaded cassette 104 also can be picked up at a location for the pharmacy entity.
Advantageously, the preloading of the cassette eliminates the problems noted above regarding incorrect loading of a dispenser due to the patient or other person manually loading medications into a dispenser. Further, sealing the compartments in cassette 104 makes the cassette child-proof and reduces the possibility of the patient or other person accessing the compartments and possibly removing or adding medications such that the medications in the compartment are no longer in compliance with the medication regimen for the patient. Dispensing element 102 extracts pills from the appropriate compartment at the appropriate time.
Apparatus 100, for example, cassette 104 and/or computer 170 provide embedded intelligence. For example, identification element 128 can include a unique bar code identifier, such as a quick response code, radio frequency identification, a near field communication (NFC) tag or any similar device known in the art. Apparatus 100 is locally or remotely programmable to access and recognize element 128 as noted above. Thus, element 102 can determine whether a particular cassette has been installed into the correct dispenser and contains the correct medications. As noted above, when an incorrect cassette is detected, dispenser element 102, for example, computer 170, transmits alarm signal 132 and implements sensory alarm signal 136. Entity 202 and/or monitoring service 134 can notify the patient, a caregiver for the patient, and/or the pharmacy entity to rectify the situation. Also as noted above, element 102 can block extraction of medications from an incorrect cassette.
Advantageously, apparatus 100 provides an intuitive interface for the patient. For example, apparatus 100 can include user interface 190 including a touch screen able to implement enable typical computer interface functions, speech synthesis, and speech recognition. In an example embodiment, apparatus 100 provides a communication link between a patient and a remote caregiver or monitoring service 134.
As noted above, blister pack configurations may not be ergonomically optimal for patient use. Advantageously, apparatus 100 does not require the patient or caregiver to read labels and manipulate a blister pack. Instead, pills, such as pills 122 and 162, are dropped into a cup or other container that is easily accessed by the patient or caregiver.
Communication among apparatus 100 and entities 204, 214, and 222/228 can be by any means known in the art including hardwired communications or radio-frequency communications.
To enhance medication adherence, element 102 reliably indexes cassette 104 to the appropriate compartment 120 at the appropriate time and dispenses the appropriate medication at the appropriate dosages. Apparatus 100 communicates faults or anomalies back to monitoring service 134, the patient, and/or a caregiver. The faults or anomalies include, but are not limited to:
Advantageously, apparatus 100 provides the patient and/or caregiver flexible exception handling in the event normal routines do not apply. For example, a ‘pre-dispense’ or ‘post-dispense’ function can be enabled to dispense one or more doses early or late if the patient plans to be unavailable at the scheduled dosage time. In an example embodiment, input 140 can be used to signal exception handling and time interval 142 can be used to provide the time before or after the scheduled dosage for the exception handling.
In an example embodiment, user interface 190 provides a prompt to remove an empty cassette and install a new/full one. In an example embodiment, cassette 104 is loaded so that lid 186 and port 126 are facing downward. The port is located above a user access point for dispensed medications. Actuator 188 rotates lid 186 or body 177 to unlock the cassette. In an example embodiment, actuator 188 rotates body 177 to move the next compartment 120 in line with port 126. In an example embodiment, actuator 188 rotates lid 186 to move the next compartment 120 in line with port 126. Thus, pills from successive compartments fall out as they are aligned with the aperture.
In the example of
From an environment perspective, cassettes 104 can be reusable, eliminating or reducing packaging waste streams. From a security perspective, cassette-based distribution provides versatility in tracking of medications, particularly any narcotic or controlled substances. For example, each cassette can easily be provided with its own passive or active identifier.
It will be appreciated that various of the above-disclosed and other features and functions, or alternatives thereof, may be desirably combined into many other different systems or applications. Various presently unforeseen or unanticipated alternatives, modifications, variations, or improvements therein may be subsequently made by those skilled in the art which are also intended to be encompassed by the following claims.
