It should be appreciated that all combinations of the foregoing concepts and additional concepts discussed in greater detail below (provided such concepts are not mutually inconsistent) are contemplated as being part of the inventive subject matter disclosed herein and may be implemented to achieve the benefits as described herein. Additional features and aspects of the disclosed system, devices, and methods will become apparent to those of ordinary skill in the art upon reading and understanding the following detailed description of the example implementations. As will be appreciated by the skilled artisan, further implementations are possible without departing from the scope and spirit of what is disclosed herein. Accordingly, the drawings and associated descriptions are to be regarded as illustrative and not restrictive in nature.
The accompanying drawings, which are incorporated into and form a part of the specification, schematically illustrate one or more example implementations of the disclosed inventive subject matter and, together with the general description given above and detailed description given below, serve to explain the principles of the disclosed subject matter, and wherein:
Example implementations are now described with reference to the Figures. Reference numerals are used throughout the detailed description to refer to the various elements and structures. Although the following detailed description contains many specifics for the purposes of illustration, a person of ordinary skill in the art will appreciate that many variations and alterations to the following details are within the scope of the disclosed inventive subject matter. Accordingly, the following implementations are set forth without any loss of generality to, and without imposing limitations upon, the claimed subject matter.
As previously stated, disclosed example implementations relate in general to drug delivery systems, devices and methods, and more specifically to systems, devices, and methods for remotely controlling or affecting the operation or functionality of pulmonary drug delivery devices and other types of inhalers utilizing electrohydrodynamic (EHD) atomization processes or other aerosol-based processes. Disclosed aerosolization devices include pulmonary drug delivery devices and inhalers utilizing specific electrohydrodynamic (EHD) atomization processes such as those disclosed in U.S. Pat. Nos. 7,931,020 and 7,849,850, both of which form part of this disclosure and are included herein, in their entirety, in the appendix attached hereto. These systems and devices also include data collection capabilities as well as capabilities that include the communication of the collected data using various wireless technologies such as, for example, Bluetooth, Zigbee, IR, and the like.
Example implementations of the disclosed system, device, and method include three basic components: (i) an inhalation device; (ii) a controller in two-way communication with the inhalation device; and (iii) a remote server in two-way communication with the controller.
Environmental sensors 110 may include pressure, temperature and humidity sensors. Subsystem health monitor 112 monitors the various subsystems of the device including, for example, power levels, sub-system states, and dose remaining. Aerosolization engine 114 delivers desired aerosolization dosages. Communication unit 116 may include any suitable hardware, firmware, gateware, software, or any combination thereof for communicating with controller 200. Communication unit 116 may be configured to transfer data using standard protocols such as ANT+, Bluetooth, IR, or any other compatible protocol. Reciprocal communication interface 150 may be configured to switch between two or more protocols that have different data transmission rates and different power consumption rates. For example, if Bluetooth is used, communication may switch between Bluetooth base rate/enhanced data rate (BR/EDR) and Bluetooth Low Energy (BLE) protocols depending on volume of data to be transmitted and on power capability. Controller 200 may both transmit and receive data and/or commands to and/or from device 100. Either controller 200 or device 100 may periodically initiate communications with the other to see if any data should be transferred or if various commands are to be processed. Controller 200 may periodically communicate with remote server 300 to determine whether commands should be relayed to or from device 100.
For some active ingredients (e.g., narcotics, opioids, and cannabis-based products, including CBD, CBG, and THC), device 100 can be locked so that it cannot be aerosolized without further authentication of user identity.
Other examples of collected and transmitted data include patient usage history; compliance with prescribed or recommended dosages or amounts; quantity or frequency of doses; volume or amount of formulation or active ingredient delivered to patient by device; formulation lot information; and any other data or information that is useful to a patient, physician, or caregiver. The disclosed pulmonary drug delivery devices and inhalers are or may be in electrical or digital communication with a device such as a smartphone that includes a visual display and interface. Through this type of interface, queries may be directed toward a user of the device including questions regarding drug effects and effectiveness and questions regarding current health status of the user. System and device capabilities include tracking usage, thereby facilitating automatic on-line ordering of refill drug cartridges. Because EHD is primarily an electrical process and not a mechanical aerosolization method as in other pulmonary delivery methods, any desired sensors and controls may be implemented and included with relative ease.
Various implementations of the disclosed systems and devices provide the combination of a highly repeatable, precise, rapid onset delivery method such as EHD with data collection and wireless communication to a mobile device or network. This combination facilitates improvements to the current standard of care for inhaled drug delivery for both patients and consumers by providing: (i) more precise, real time feedback and traceability regarding device usage; and (ii) the source and amount of active ingredient delivered to the patient or consumer. The collection of such data combined with user responses to validated questions provides valuable insight regarding next generation drug/device development.
Among other advantages, uses, and functions, patient and user compliance with prescriptions or recommended dose limits can be discretely managed with the disclosed systems and devices. Other available inhalers or inhalation device technologies exhibit slower or more gradual pharmacokinetic profiles, thereby resulting in a longer delay between when a substance or composition is delivered and when relief or the desired result is obtained by the user. Accordingly, with other inhalation devices, a patient or user may dose themselves multiple times to get the same relief or derive the same benefit, thus possibly resulting in overdosing. The combination of precise repeatable delivery with a method of communicating to the user that the appropriate or maximum dosage has been reached is a specific advantage provided by the disclosed systems and devices. Additionally, this information may be communicated to caregivers, doctors, and other parties as an aspect of managing the patient care.
The disclosed systems and methods are particularly useful for applications wherein real-time feedback of dose frequency and dosage amounts are important, and wherein traceability of active ingredients (e.g., as narcotics, opioids, and cannabis-based products, including CBD, CBG, and THC) is of concern. As the risk of counterfeit drugs and supplements increases, the traceability of an active ingredient or formulation provided by the disclosed systems and methods may be used to prevent or greatly reduce the introduction, distribution, and use of counterfeit drugs or supplements.
