G16H 20/10

Abstract:

A controller in a system for automatic control of blood glucose level of a subject is operative to generate an insulin dose control signal for controlling insulin delivery by a delivery device, based on time-varying glucose levels of the subject as represented by an actual glucose level signal over time. The controller operates at a regular frequency to generate the insulin dose control signal to regulate the glucose levels in the subject and employs a control algorithm that functions in conjunction with and accounting for user-determined doses, such as meal doses, whose values are entered into the controller and delivered on command of a user.

Edward R. Damiano - Acton MA, US

International Classification:

A61M 5/172

Abstract:

An automated blood glucose control system is configured to generate a backup therapy protocol comprising insulin therapy instructions derived from autonomously determined doses of insulin. The system generates a dose control signal using a control algorithm configured to autonomously determine doses of insulin to be infused into a subject for the purpose of controlling blood glucose of the subject based at least in part on a glucose level signal received from a glucose sensor. The system can track insulin therapy administered to the subject over a tracking period, including storing an indication of the autonomously determined doses of insulin delivered to the subject as basal insulin, as correction boluses of insulin, or as mealtime boluses of insulin. The system can generate a backup injection therapy protocol or a backup pump therapy protocol with insulin therapy instructions based at least in part on the insulin therapy administered to the subject over the tracking period.

G06F 3/0488
G06F 3/0484
A61M 5/142

Abstract:

Systems and methods presented herein relate to cancelling a modification of medicament delivery initiated by a user. A display of a therapy control element can be generated on an interface, such as a touchscreen. The therapy control element permits a user to modify a control parameter used in a control algorithm for generating a dose control signal for delivering medicament to a subject. Responsive to receiving the modification, the control parameter may be modified at a first time from a first setting to a second setting based on an indication of the modification to the therapy control element. Responsive to receiving a restore gesture on the touchscreen at a second time, the control parameter may be restored back to the first setting. This restore gesture may be a swipe gesture performed by a user.

Abstract:

Systems and methods are disclosed herein for switching an application executing on an ambulatory medical device to a new application without interrupting therapy provided by the ambulatory medical device to a subject. The ambulatory medical device may receive an indication that an update to an application executing on the ambulatory insulin pump is available, establish a communication connection to a host computing system, download and install the application update, while a prior version of the application continues to run. The disclosed systems and methods can confirm successful installation of the application update on the ambulatory medical device and switch control of the ambulatory medical device from the prior version to the new version of the application without interrupting therapy provided to the subject.

International Classification:

A61M 5/172
G08B 21/18
A61M 5/142

Abstract:

Systems and methods relate to an ambulatory medicament device that can generate a dose control signal to cause a medicament pump to infuse medicament into a subject. The system can analyze status to determine whether an alarm condition for the ambulatory medicament device or for a subject is already present in a list of pending alarm conditions. If the alarm is not present, the system can determine a severity level of the alarm condition from among a plurality of severity levels and annunciate the alarm condition using one or more annunciation patterns selected based on the severity level of the alarm condition for the medicament device or for the subject. The system may maintain an indication of the alarm condition on the list of pending alarm conditions until the alarm condition is resolved.

Abstract:

Systems and methods are disclosed herein for switching control of an ambulatory medical device from an application executing on the ambulatory medical device to a safe version or a new version of the application without interrupting therapy provided by the ambulatory medical device to a subject. The ambulatory medical device can maintain copies of a safe version and a new version of the application. The disclosed systems and methods can execute the new version, while the prior version of the application continues to execute, determine whether a minimum set of operating conditions are satisfied by the new version, and switch control of the ambulatory medical device from the prior version to the new version. The systems and methods can also automatically revert to the safe version of the application case the current version is malfunctioning without interrupting therapy provided to the subject.

Abstract:

An automated blood glucose control system can provide automatic delivery of glucose control therapy to a subject and receive information about manual glucose control therapy provided to the subject. The automated blood glucose control system can indicate an amount of a bolus of medicament via a control algorithm configured to control blood glucose level in the subject. The automated blood glucose control system can indicate an amount of a manual bolus of medicament, which can be used to model a diminishment of the medicament in the subject over time based at least in part on the manual bolus of medicament.
