A needle mechanism module for automatically inserting a fluid path into a patient for drug delivery is provided. The needle mechanism module can be a component of a wearable drug delivery device. The needle mechanism module can insert a needle and cannula into the patient responsive to activation of the drug delivery device by a user. After insertion, the needle can be automatically retracted, leaving only the cannula in the patient. As a result, discomfort of the user is reduced.

Fill stations and base stations are provided for personal pump systems. The fill stations may be opened and closed to accept a reservoir and to allow fluid to be introduced into the reservoir for use with personal pump systems. The fill stations may hold the reservoir at a tilt relative to an underlying surface and may discourage overfilling of the reservoir. The filling stations may also include viewing windows having fluid lines marked thereon for indicating volume of fluid within the reservoir.

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.

The present it relates to a sensor applicator assembly for a continuous glucose monitoring system and provides a sensor applicator assembly for a continuous glucose monitoring system, Which is manufactured with a sensor module assembled inside an applicator, thereby minimizing additional work by a user for attaching the sensor module to the body and allowing the sensor module to be attached to the body simply by operating the applicator, and thus can be used more conveniently. A battery is built in the sensor module and a separate transmitter is connected to the sensor module so as to receive power supply from the sensor module and be continuously used semi-permanently, thereby making the assembly economical. The sensor module and the applicator are used as disposables, thereby allowing accurate and safe use and convenient maintenance.

A device and method are disclosed for an elastic strip with a first fixed end and a second movable end, the elastic strip configured to be in at least one of a tense state and an elastic state. A release mechanism is configured to maintain the elastic strip in a tense state when the release mechanism is in a holding state, and configured to release the elastic strip when in a release state. A needle path with a first bend is provided. A rigid needle is configured to traverse a first portion of the needle path when the elastic strip is in the elastic state and a cannula is located in the needle path and configured to traverse a second portion of the needle path when the rigid needle traverses the first portion of the needle path.

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 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.

The present invention relates to an infusion device comprising a housing; a compartment inside said housing for positioning a medicament container, an infusion needle arranged to said housing, being connectable to said medicament container for delivering a dose of medicament, a piston plunger arranged in said housing capable of acting on said medicament container for delivering a dose of medicament, mechanical drive means capable of acting on said piston plunger for delivering a dose of medicament. The invention is characterised in that said piston plunger comprises a number of distinct segments being inter-connectable to each other for forming an elongated piston plunger.

Disclosed is an injection device including: —a needle support; —an injection needle integral with the needle support and having a free end arranged away from the needle support; and—a needle extraction mechanism including a base connected to the needle support and a plunger movable relative to the base between a needle use position and a needle extraction position. The base is movable relative to the needle support between an inactive position of the extraction mechanism and an active position of the extraction mechanism. The plunger includes an outer member and an inner member, movable relative to the outer member, from a retracted plunger configuration to a deployed plunger configuration wherein the plunger length is greater than in the retracted configuration.
