An apparatus for insertion of a medical device in the skin of a subject is provided, as well as methods of inserting medical devices. Embodiments include removing a substantially cylindrical cap from an inserter to expose a substantially cylindrical sleeve, removing a cover from a substantially cylindrical container holding sensor components, and fitting the sensor components into the inserter.

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.

Biomonitoring systems and methods of loading and releasing the same are disclosed herein. In one embodiment, a biomonitoring system includes a wearable sensor patch and an applicator. The sensor patch has a filament and an electronics subsystem. The sensor patch is configured to detect a parameter of an analyte in fluid of a user when it is adhered to the user's skin and the filament extends into the user's tissue. The applicator includes first and second applicator portions and a spring positioned within an interior of the second application portion between the first and second applicator portions. When the applicator transitions from a loaded mode to a released mode, the spring transitions from a first state of compression to a second, lower state of compression and accelerates the first applicator portion and the wearable sensor patch toward the user's skin such that the filament extends into the user's tissue.

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.

Wearable sensor patches, applicator systems for applying wearable sensor patches, and associated systems, devices, and methods are disclosed herein. In one embodiment, an applicator system includes a first applicator portion, a second applicator portion, a spring, and a trigger mechanism. The first applicator portion releasably retains a wearable sensor patch configured to detect a parameter of an analyte in fluid of a user. When the applicator system is in a loaded mode, the spring and the first applicator portion are positioned within the second applicator portion such that the spring is positioned between the first applicator portion and the second applicator portion. The trigger mechanism is configured to initiate a transition of the applicator system from the loaded mode to a released mode such that the spring accelerates the first applicator portion distally away from the second applicator portion to apply the wearable sensor patch to the user.

Disclosed herein are devices, apparatus, systems, methods and kits for collecting and storing a fluid sample from a subject. A device for collecting the fluid sample can include a housing comprising a recess having an opening, a vacuum chamber in the housing and in fluidic communication with the recess, and one or more piercing elements that are extendable through the opening to penetrate skin of the subject. The vacuum chamber can be configured for having a vacuum that draws the skin into the recess. The recess can be configured having a size or shape that enables an increased volume of the fluid sample to be accumulated in the skin drawn into the recess.
