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.

Abstract: Systems and methods presented herein relate to a method of sharing therapy data of an ambulatory medical device with a computing system of a networked computing environment. The computing system may be identified using an authorized system list that includes an address of approved computing systems. Using an address of an approved computing system, a direct end-to-end data connection may be established via a wireless wide area network. A public key of the computing system may be received permitting the ambulatory medical device to encrypt data to be transmitted to the computing system. The ambulatory medical device can transmit the encrypted therapy data to the computing system over the direct end-to-end data connection.

Abstract: A blood glucose control system can generate an indication of total carbohydrate therapy over a period during use by a subject. The system can be connected to a medicament pump configured to deliver insulin therapy, other types of medicament therapy, or a combination of medicament therapies to the subject. The system can determine an amount of a counter-regulatory agent to respond to an impending risk of hypoglycemia or an episode of hypoglycemia and determine a dose of carbohydrate therapy based at least in part on the amount of the counter-regulatory agent. The system can track determined doses of carbohydrate therapy to generate the indication of total carbohydrate therapy over the period.

Abstract: A glucose control system employs adaptation of a glucose target (set-point) control variable in controlling delivery of insulin to a subject to maintain euglycemia. The glucose target adapts based on trends in actual glucose level (e.g., measured blood glucose in the subject), and/or computed doses of a counter-regulatory agent such as glucagon. An adaptation region with upper and lower bounds for the glucose target may be imposed. Generally the disclosed techniques can provide for robust and safe glucose level control. Adaptation may be based on computed doses of a counter-regulatory agent whether or not such agent is actually delivered to the subject, and may be used for example to adjust operation in a bihormonal system during periods in which the counter-regulatory agent is not available for delivery.

Abstract: Multi-medicament infusion systems prevent cross-channeling of medicaments. A system may include one or more of an infusion pump, medicament reservoirs, a multi-channel fluid conduit, and an infusion set. Medicament reservoirs and/or collars may be sized and shaped differently such that the medicament reservoirs can only be inserted into the system under selected configurations.

Abstract: A blood glucose control system is configured to modify therapy provided to a subject. The system can cause first therapy to be delivered by the blood glucose control system to a subject during a first therapy period. The first therapy can be delivered based at least in part on a first value of a control parameter used by a control algorithm to generate a dose control signal. The system can determine a first effect corresponding at least in part to the first therapy and autonomously generate a second value of the control parameter. The system can cause second therapy to be delivered by the blood glucose control system to the subject during a second therapy period, wherein the second therapy is delivered based at least in part on the second value of the control parameter.

Abstract: A multi-medicament infusion system (10) for preventing the mischanneling of medicaments may include an infusion pump (12), medicament reservoirs (16A,16B), a multi-channel lumen (18), and an infusion set (20). The medicament reservoirs may be sized and shaped differently such that the medicament reservoirs can only be inserted into the infusion pump in a unique configuration. The multi-channel lumen may include connectors that mate to corresponding connectors on the infusion pump and the infusion set only in a unique configuration. Because the various parts of the multi-infusion system may only be connected in the unique configuration, the expected medicaments may be administered appropriately and channeled to the correct infusion sites.

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: An ambulatory medicament device can automatically resume medicament delivery after medicament delivery to a subject is suspended. Suspension of medicament delivery can occur for a temporary suspension period associated with a length of time that the delivery of the medicament is to be suspended. Resuming medicament delivery can occur upon determining that a resumption condition has occurred during the temporary suspension period.

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: 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.
