DETAILED DESCRIPTION

(5) Referring to FIG. 1, an automated prescription dispensing system network topology according to an example embodiment is shown. Automated prescription dispensers 102 are installed in patient homes. The dispensers comprise a dispensing tray or cartridge that holds each patient's medications. The dispensers are Internet-enabled and accessible from one or more remote centers. The automated prescription dispensers 102 may be programmed to transmit information periodically or continuously to the remote centers and to permit remote access from users at remote centers. In addition to transmitting and receiving data, the automated prescription dispensers 102 may have remote administration capabilities to facilitate software and other system updates at the devices.

(6) Users at a remote medication operations center 106 monitor the inventory of prescriptions and medications in each patient's dispenser and arrange to replenish each dispenser according to each patient's needs. Users at a remote patient monitoring center 100 monitor patient use of the dispensers. Status data regarding the patient's use of the dispenser as well as data indicative of the patient's condition while using the dispenser may be transmitted to the remote patient monitoring center 100 so that a user can confirm the patient is using the dispenser properly and has not experienced any adverse events related to using the dispenser, taking the medications, etc. A connection between the dispenser 102 and a remote data analytics server center 104 facilitates the transmission of data regarding the appropriate prescriptions and medications to be dispensed to the patient. Data related to the patient's prescriptions and medications is received at the data analytics center 104 from a remote medical center 108. Such a medical center may comprise a medical center server which contains patent data. An analytical engine at the data analytics center 104 may detect changes in the patient's prescriptions or medications based on data in electronic medical records received from the remote medical center 108. If a doctor changes a patient's medication or dosage, data for the dispenser is updated automatically and seamlessly.

(7) Remote patient monitoring services as well as medication operations services may be provided by a single service provider or multiple service providers. One of skill in the art would understand that one or more software applications executing on one or more servers at one or more locations may support the remote patient monitoring services as well as remote medication operations services. One of skill in the art would understand there are various ways to implement the features and functionality described herein in one or more software applications and that the topology shown in FIG. 1 is illustrative of one possible embodiment.

(8) Referring to FIG. 2, a diagram of an automated prescription dispenser according to an example embodiment is shown. In an example embodiment, the dispenser 120 comprises a release component or mechanism (e.g., button or lever) to release a dispensing tray or cartridge from the dispenser. The dispenser may further comprise a computer display 124 and one or more buttons 126 for interacting with the dispenser. The dispenser dispenses medications in a standardized tray or cartridge 122 that can be reloaded according to the patient's needs.

(9) For security purposes, the dispenser 120 may be equipped with a security component such as a scanner or sensor to perform biometric validation. For example, the dispenser may be equipped with a finger print or retinal scanner. Biometric validation provides easy and secure access and frees the patient from having to remember and enter a code. The dispenser 120 may have an alert feature (e.g., flash and/or beep) when a cartridge or tray 122 is dispensed so the patient knows the validation was successful.

(10) The dispenser 120 may be programmed to allow access only once per day. It may further detect when the dispenser is not accessed or the dispensed tray or cartridge 122 is not lifted after a configurable inactivity period such as 8 to 24 hours. Using the Internet connectivity features, the dispenser may be programmed to issue an alert to a remote caregiver if the patient fails to access the dispenser or lift the tray or cartridge 122 within the specified time period.

(11) When the tray or cartridge is lifted, a camera may start to capture streaming video or photographs for viewing at a remote monitoring station. The viewer can examine patient habitus (e.g., edema, shortness of breath, instability). A patient that is experiencing difficulty in using the dispenser or that exhibits another health condition or acute episode may access a “Do Not Understand” or “Panic” button for immediate assistance via voice and/or video. In an example embodiment in which two-way communication is supported, a remote caregiver may communicate with the patient and ask questions or notify the patient that help is on the way.

(12) Referring to FIG. 3, a sample dispensing tray or cartridge 122 according to an example embodiment is shown. In an example embodiment, the dispenser dispenses a “One Tray Per Day Unambiguous Single Day Planner” cartridge 122. The tray or cartridge 122 comprises a plurality of compartments 132 corresponding to different times of the day. In an example embodiment, the tray or cartridge comprises 24 compartments, one for each hour of the day. In an alternative embodiment, the tray may comprise three compartments: one for morning; one for afternoon; and one for evening. The trays or cartridges may be configured in a variety of ways to meet the needs of different patient populations. Each compartment 132 may be loaded with the pills or medications the patient should take at the specified time of day.

(13) Using a remote monitoring and communication connection such as an Internet connection, the dispenser may transmit supply status data and usage statistics in real-time to a remote patient monitoring center and/or remote medication operations center. Such centers may comprise medication operations servers, patient monitoring servers, operations personnel, and monitoring personnel. Referring to FIG. 4, a sample monitoring display screen 140 according to an example embodiment is shown. The screen comprises identifying information for a patient 142, details regarding the patient's access to the tray and medicine dosages remaining 144, and image data from the camera 146. A service representative at the remote patient monitoring center 100 may review the information to determine whether medications have been taken as required or whether the patient may require some assistance. The representative may further determine whether the patient is in need of a replacement cartridge.

(14) The automated prescription dispensing system and method of the present disclosure simplifies the administration of medication for elderly and chronically ill patients who may have difficulty adhering to a medication regime. The automated prescription dispensing system and method frees a patient, especially an elderly or frail patient, from worrying about which medication to take at which time. Patients that use numerous medications can dispose their unused or partially used pill bottles from prior hospital admissions that may be scattered around their home. The automated prescription dispensing system and method and the in-home prescription dispenser facilitates the proper administration of medicine and reduces the likelihood of various complications that may result from improper administration of medication as well as further admissions to in-patient facilities due to acute conditions arising from medication errors. The ability to adhere to a medication regime with assistance from an automated prescription dispensing system and method as disclosed may allow many patients to remain in their homes and to experience a higher quality of life.
