Abstract
Systems and methods for automatically delivering medication to a user. An automated drug delivery system may include a sensor and a wearable automated drug delivery device. The wearable automated drug delivery device may be configured to couple to the skin of a user and may include a controller and a pump. The pump may be configured to output the medication. The controller may be within the wearable automated drug delivery device. The sensor may be coupled to the user and may be configured to collect information regarding the user. The controller of the wearable automated drug delivery device may use the collected information to locally determine an amount of medication to be output from the wearable automated drug delivery device and cause delivery of the amount of medication.
Core Innovation
The invention describes an automated drug delivery device with a housing that includes a reservoir configured to contain a medication, a pump configured to transfer the medication from the reservoir, and a power supply operable to supply power to the pump. The device further includes a needle and/or cannula configured to dispense the medication and a needle insertion device operable to deploy the needle and/or the cannula into skin of a user. The device is configured to receive signals over a wireless link via a receiver and to store an algorithm in memory coupled to a controller.
When executing the algorithm stored in the memory, the controller locally receives sensor data from a glucose sensor positioned on the skin of a user. Based at least in part on the received sensor data, the controller locally determines a size of a dose of medication and at least a change in a time of delivery, a frequency of delivery, or a schedule of future delivery of the dose. The controller causes the pump to deliver medication from the reservoir based on the determined dose size and the at least the change in a delivery timing attribute.
In wearable implementations, the invention includes a glucose sensor coupled to skin of a user and a wearable medical device coupled to the skin of the user that includes the reservoir, pump, power supply, needle and/or cannula, needle insertion device, receiver, memory, and controller. The controller locally determines the dose size and delivery timing changes based on the sensor data and causes the pump to deliver the medication accordingly. The disclosed architecture also includes wireless receiver/transmitter/transceiver options via an intermediate electronic device and mechanical embodiments for needle/cannula deployment and safety/latch mechanisms.
Claims Coverage
The partial content identifies three independent claims, each directed to a wearable or automated drug delivery architecture that uses a glucose sensor and a locally executing algorithm to determine dose size and at least one delivery-timing change. Across the independent claims, the inventive features focus on local determination from skin-positioned glucose sensor data and pump delivery based on the locally determined dose and delivery timing attribute changes.
Locally determining dose size and delivery timing change from skin glucose sensor data
An automated drug delivery device where, when executing an algorithm stored in memory, the controller locally receives sensor data from a glucose sensor positioned on the skin of a user, determines locally a size of a dose of medication and at least a change in a time of delivery, a frequency of delivery, or a schedule of future delivery of the dose based at least in part on the received sensor data, and causes the pump to deliver medication from the reservoir based on the determined dose size and the at least the change in the time of delivery, the frequency of delivery, or the schedule of future delivery.
Wearable drug delivery system with glucose sensor and local algorithm-driven pump control
A wearable drug delivery system comprising a glucose sensor coupled to skin of a user and a wearable medical device coupled to the skin of the user that includes a reservoir, pump, power supply, needle and/or cannula, needle insertion device, receiver, memory, and controller; the controller executes the algorithm stored in memory to locally receive sensor data from the glucose sensor, determine locally a size of a dose of medication and at least a change in a time, frequency, or schedule of future delivery of the dose based at least in part on the received sensor data, and cause the pump to deliver medication based on the determined dose size and the at least the change in the time, frequency, or schedule.
Manual or remote-command needle insertion with direct sensor data receipt
A wearable drug delivery system where the needle insertion device is a manual activation device responsive to a manual pressure or an electrical activation device responsive to a command from a remote device; the controller locally receives sensor data directly from the glucose sensor, determines locally a size of a dose of medication and at least a change in a time, frequency, or schedule of future deliveries of the medication based at least in part on the received sensor data, and causes the pump to deliver medication from the reservoir based on the determined dose size and the at least the change in the time of delivery, the frequency of delivery, or the schedule of future deliveries.
Across the independent claims, the common inventive core is a skin-coupled glucose sensor providing sensor data to a controller that locally executes an algorithm to determine dose size and at least one delivery-timing change, and to cause the pump to deliver the medication from the reservoir. Claim variations specify the wearable system architecture, including the receiver and wireless link arrangement, and refine needle insertion activation as manual or electrical with remote-command response, while maintaining local control based on received glucose sensor data.
