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.

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.

Various improvements are provided to breathing training, monitoring and/or assistance devices. A portable device is provided which optionally includes a gas canister, a feedback system for implementing pressure control, and a visual output for indicating adherence to a breathing exercise to the user. The pressure control may provide regulation of different pressures for inhalation and exhalation.

A wearable infusion pump assembly includes a reusable housing assembly, and a disposable housing assembly including a reservoir for receiving an infusible fluid. A releasable engagement assembly is configured to allow the reusable housing assembly to releasably engage the disposable housing assembly. A detachable external infusion set is configured to deliver the infusible fluid to a user.

A device that regulates, monitors, and provides data on the progress of a large-volume injector during its injection sequence. The device comprises an injector and a monitor assembly. The injector has a syringe having a plunger, and a biasing device that biases the plunger through the syringe. The monitor assembly comprises a resistance unit configured to resist movement of the plunger, a gear connected to the plunger by the resistance unit, and a control unit configured to monitor the position, and regulate the rotation, of the gear. Wherein linear movement of the plunger causes the gear to rotate so that the control unit generates information on the position of the plunger.

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 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.
