A physiological sensor history backfill system and method including a method of sensor history backfill for a local base device operable to wirelessly communicate with a physiological sensor connected to a patient, the method including: obtaining physiological readings for the patient at a predetermined interval; storing the physiological readings at the physiological sensor as sensor physiological readings; storing the physiological readings at the local base device as historic physiological readings; obtaining a current physiological reading for the patient; transmitting the current physiological reading to the local base device in a current reading message; detecting a record gap in the historic physiological readings between the current physiological reading and the historic physiological readings; and filling the record gap in the historic physiological readings with sensor physiological readings from the physiological sensor when the current reading message does not include the sensor physiological readings to fill the record gap.

Physiological sensor history backfill system and method

Infusion systems, infusion devices, and related operating methods are provided. An exemplary infusion device includes a motor operable to deliver fluid to a body of a user, a first control module to enable input power for the motor and provide a dosage command for operating the motor, and a second control module coupled to the first control module to receive the dosage command and operate the motor using at least a portion of the input power based at least in part on the dosage command. One of the first control module and the second control module detects an anomalous condition, and in response, disables the input power to the motor, stores diagnostic information for the anomalous condition in its internal memory, and automatically resets thereafter.

Error handling in infusion devices with distributed motor control and related operating methods

Infusion systems, infusion devices, and related operating methods are provided. An exemplary method involves operating an infusion device to deliver fluid to a user in accordance with a first operating mode of a plurality of operating modes, obtaining operational information pertaining to the first operating mode, and obtaining clinical information pertaining to the user. A destination operating mode of the plurality of operating modes is determined based at least in part on the operational information and the clinical information, and the infusion device is operated to deliver the fluid in accordance with the destination operating mode in a manner that is influenced by at least a portion of the operational information pertaining to the first operating mode.

Methods for operating mode transitions and related infusion devices and systems

Infusion systems, infusion devices, and related operating methods are provided. An exemplary infusion device includes a motor operable to deliver fluid to a body of a user, a first control module, and a second control module. The first control module and the second control module are coupled to one another. The first control module enables input power for the motor in accordance with a handshaking sequence of communications between the first control module and the second control module and provides a dosage command to the second control module, with the second control module operating the motor using the input power based on the dosage command in accordance with the handshaking sequence of communications.

Infusion devices with distributed motor control and related operating methods

An external infusion device for delivering insulin from a reservoir into a body of a user includes the capability to deliver time-shifted basal insulin. The external infusion device includes at least one drive mechanism operatively couplable to the reservoir to deliver insulin into the body of the user, at least one processor to control the external infusion device, at least one power supply, at least one display device operatively coupled to the processor to provide visual information to the user, at least one input device operatively coupled to the processor to allow the user to command the processor, and a housing. Time-shifting of basal insulin occurs when a portion of basal insulin is added to a bolus, to a current basal rate, or to a bolus and a current basal rate.
