A repeater system may control a pump by using a repeater and a user interface. An adhesive patch system may be used for affixing a pump or other object to a human body. Such an adhesive patch system may include two sets of adhesive members, each member including an adhesive material on at least one side so as to attach to the body. The members of the first set are spaced to allow the members of the second set to attach to the body in spaces provided between the members of the first set, and the members of the second set are spaced to allow members of the first set to detach from the body without detaching the members of the second set. Also, fill stations and base stations are provided for personal pump systems.

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.

Systems and methods are disclosed herein for monitoring the status of an ambulatory medical device and the health condition of a subject that receives therapy from the ambulatory medical device. The ambulatory medical device can have a touchscreen display user interface to receive input signals from a user and display alarm conditions associated with the status of an ambulatory medical device or health condition of a subject. The disclosed methods and systems can determine whether status information received from a monitoring system interface satisfies an alarm condition for the ambulatory medicament device or for the subject. If the status information satisfies an alarm condition, the touchscreen user interface can display one or more alarm status indicators corresponding to the alarm condition. The user can activate a therapy change interface on the touchscreen display and modify a control parameter of the ambulatory medical device that controls the therapy delivery to the subject.

An ambulatory medicament device can generate a dose control signal for delivery of medicament to a subject and secure at least some functionality of a user interface of the ambulatory medicament device. The ambulatory medicament device can have a locked state that restricts modification of at least one control parameter. The ambulatory medicament device can have an unlocked state that allows modification of at least one control parameter. The ambulatory medicament device can accept a user input of a security code that is validated against a passcode to enter from the locked state to the unlocked state.

An ambulatory medical device can detect a device condition and determine if the device condition satisfies a set of normal operating parameters. If the normal operating parameters are not satisfied, the ambulatory medical device can determine if the device condition stratifies a set of minimum operating parameters. If the minimum operating parameters are satisfied, the ambulatory medical device can maintain a delivery of therapy to a subject and generate an alert based on the device condition.

A method for controlling a device using a shape-memory alloy wire is disclosed. The method includes determining an ontime for the shape-memory alloy wire based on a target volume to be pumped by a pump plunger, determining the temperature of the shape-memory alloy wire and adjusting the ontime based on the temperature of the shape-memory alloy wire.

A flow generator for delivering breathable gas to a patient includes a processor coupled with operation sensors and a user interface. The processor is programmed to generate at least one of time-based or event-based messages relating to at least one of flow generator operation, flow generator service, flow generator use, patient health, peripheral devices and services, patient treatment, and reminders. Time-based messages are generated at predetermined time intervals based on either time of use or elapsed time. The event-based messages are generated based on signals from the operation sensors. The user interface is configured to deliver the messages to at least one of a display, a flow generator service provider, the patient and a physician. By this system, operation of the flow generator is facilitated and enhanced.

A patch-sized fluid delivery device may include a reusable portion and a disposable portion. The disposable portion may include components that come into contact with the fluid, while the reusable portion may include only components that do not come into contact with the fluid. Redundant systems, such as redundant controllers, power sources, motor actuators, and alarms, may be provided. Alternatively or additionally, certain components can be multi-functional, such a microphones and loudspeakers that may be used for both acoustic volume sensing and for other functions and a coil that may be used as both an inductive coupler for a battery recharger and an antenna for a wireless transceiver. Various types of network interfaces may be provided in order to allow for remote control and monitoring of the device.

A method of dispensing a therapeutic fluid from a line includes providing an inlet line connectable to an upstream fluid source. The inlet line is in downstream fluid communication with a pumping chamber. The pumping chamber has a pump outlet. The method also includes actuating a force application assembly so as to restrict retrograde flow of fluid through the inlet while pressurizing the pumping chamber to urge flow through the pump outlet. A corresponding system employs the method.

Systems and methods are disclosed herein for updating an application controlling an ambulatory medical device such that application updates can be identified, downloaded and installed 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 configured to host the application update, and download the application update. The disclosed systems and methods can determine an execution time of an installation and install the downloaded application update without interrupting therapy provided by the ambulatory medical device to the subject.
