Abstract
A medicament delivery assembly comprises a delivery device configured to deliver medicament to a user, a communication accessory releasably coupled to the delivery device, and one or more sensors configured to sense a condition of the delivery device. The communication accessory may be configured to receive a first signal from the one or more sensors assembly and to send a second signal to an external device.
Core Innovation
The invention relates to an ambulatory medicament delivery system that includes a medicament delivery device and a releasable communication accessory that attaches to the medicament delivery device. The communication accessory includes a sensor positioned on the accessory and configured to sense a condition of the medicament delivery device, including activation of a bolus delivery button via a bolus delivery button indicator from the medicament delivery device.
The communication accessory is configured to receive a first signal from the sensor and to send a second signal to an external device. The accessory includes memory and an optional processor for processing and recording information from the sensor assembly, and for determining or managing signals. Wireless communication to the external device is described, including use with a mobile device software application.
The invention also includes accessory structures that support coupling, modular use, and handling. Example structures include a concave body having engagement protrusions and recesses that couple with corresponding housing engagement features of the medicament delivery device, and a relief formed where sidewalls meet an end wall that allows sidewall and end-wall movement relative to each other during coupling. The description further provides an opening or window alignment feature, waterproofing or over-molding, and modular embodiments for retrofitting existing devices and kits with multiple disposable delivery devices sharing a reusable accessory.
Claims Coverage
The independent claims cover a communication accessory that releasably couples to a medicament delivery device and includes a sensor that detects bolus delivery button activation and outputs signals to an external device. Across two independent claims, at least six inventive features are specified: accessory coupling structure, sensor sensing of bolus delivery button activation, first-signal and second-signal communication to an external device, optional stored or processed signaling via electronics, and specific mechanical and structural features including concave shape, relief movement, and a gripping lip.
Bolus button sensing on coupled medicament delivery patch
A sensor positioned on one of the two opposed side walls and configured to sense activation of a bolus delivery button via a bolus delivery button indicator from the medicament delivery device, wherein the medicament delivery device includes a patch.
Releasable accessory coupling and signal relay to external device
A communication accessory configured to releasably couple to the medicament delivery device, wherein the communication accessory is configured to receive a first signal from the sensor and to send a second signal to an external device.
Top-surface and sidewall clip coupling geometry
A communication accessory having a top surface and two opposed sidewalls extending from the top surface, the two opposed sidewalls configured to clip onto a top surface and corresponding sidewalls of a medicament delivery device.
Concave housing with engagement protrusions and recesses
A communication accessory having a concave shape, including a plurality of accessory engagement features having a plurality of protrusions and a plurality of recesses on an inner surface of the two opposed sidewalls that couple with a plurality of housing engagement features on a housing of a medicament delivery device.
Relief allowing relative movement and gripping lip
A relief formed where the sidewalls meet the end wall that allow the sidewalls and end wall to move relative to each other as the communication accessory is coupled to the medicament delivery device, and a lip that protrudes away from a surface of each of the sidewalls and provides a gripping surface.
Circuit board and battery electronics for sensor signal reception and external communication
A circuit board coupled to a battery including electronic components necessary for the communication accessory to receive one or more signals from the sensor and communicate the signals to an external device.
The claim set centers on a communication accessory that clips or releasably couples to a medicament delivery device patch, uses a sensor to detect bolus delivery button activation via a bolus delivery button indicator, and relays sensor signals as a first signal and second signal to an external device. Dependent refinements expand sensing scope and specify wireless communication and optional storage or processing, while the second independent claim further specifies concave shape, mechanical relief for relative movement, an engagement-feature coupling geometry, and electronics including a circuit board with battery.
