An infusion pump assembly includes a reservoir assembly configured to contain an infusible fluid. A motor assembly is configured to act upon the reservoir assembly and dispense at least a portion of the infusible fluid contained within the reservoir assembly. Processing logic is configured to control the motor assembly. A primary power supply is configured to provide primary electrical energy to at least a portion of the processing logic. A backup power supply is configured to provide backup electrical energy to the at least a portion of the processing logic in the event that the primary power supply fails to provide the primary electrical energy to the at least a portion of the processing logic.

A portable liquid medicine administration device for continuous or intermittent administration of a liquid medicine into a living body includes: a liquid medicine administration device main body filled with the liquid medicine; and a cradle to which the liquid medicine administration device main body is attachable and detachable. The liquid medicine administration device main body includes: an alarm unit configured to output an alarm on a basis of a notification event occurring while the liquid medicine administration device main body is attached to the cradle; and an alarm control unit configured to stop the alarm on a basis of a change occurring in a relative position between the cradle and the liquid medicine administration device main body.

Aspects of the present invention relate to an injection device configured to receive a medicament container. The injection device comprises movable means, such that before injection an information code is not visible and such that during or after injection the movable means moves to allow the code to be visible.

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.

An apparatus includes a simulated medicament delivery device and an electronic circuit system. The simulated medicament delivery device includes a housing, and is devoid of a medicament delivery mechanism that causes a medicament to be delivered. The electronic circuit system is coupled to the housing and includes an audible output device and a cover. The housing of the medicament delivery device and the cover of the electronic circuit system collectively define an acoustic enclosure. The audible output device is configured to be disposed within the acoustic enclosure.

An autoinjector includes a case adapted to hold a medicament container having a needle, a needle shroud slidably disposed in the case and translatable between an extended position relative to the case in which the needle is covered and a retracted position relative to the case in which the needle is exposed, and a plunger slidably disposed in the case. The case includes a rib. The plunger includes a plunger boss adapted to abut the rib and the needle shroud when the needle shroud is in the extended position and disengage the rib when the needle shroud is in the retracted position to allow the plunger to translate axially relative to the case.

A drug delivery device or patch-like delivery device which employs a spring force and an inclined surface to apply pressure on a fluid reservoir, thereby delivering medicament to a user's body. The slope of the inclined surface may be engineered to control the drug delivery rate. The device may be low profile and wearable, for example in the form of a patch. A visual indicator of the amount of medicament delivered or remaining may be incorporated, for example via a transparent window that shows the progression of an inclined surface as it presses on the reservoir. The device may incorporate mechanisms for automatic extension and retraction of a cannula at the beginning and end of drug delivery. Drug delivery rate may be limited with flow restrictors, and by using a two-reservoir system with a viscous liquid displacing a reservoir containing the medicament.

The present disclosure relates to an injection needle assembly for use in a medicament delivery device. The injection needle assembly comprises an injection needle holder, an injection needle fixed to said injection needle holder, the injection needle having a proximal end and a distal end, and a sealing assembly for sealing the distal end of the injection needle. The sealing assembly comprises a spacer element surrounding the distal end of the injection needle and a sealing membrane for sealing the distal end of the injection needle.

A drug delivery device system with mutable indicia and method for using same are provided. The drug delivery device system includes a syringe and/or syringe components (e.g., needle shield, needle guard), or autoinjector pen, or wearable autoinjector with mutable indicia and a software application for an external device to analyze images of the mutable indicia to automatically determine and record status of the drug delivery device. The mutable indicia or codes on the drug delivery device or its components represent different medical events such as dose completion, dose amount, and safety feature deployment or removal and can be detected by and otherwise logged by the external device. The external device may execute an application configured to further process data obtained via captured images of mutable indicia and display related information (e.g., fluid remaining in syringe barrel, delivered dose, and so on).

A system is disclosed. The system includes a reservoir for containing a fluidic medium, the reservoir including a front surface, a resilient cylindrical flexure portion connected to the front surface, the resilient cylindrical flexure portion comprising an accordion-like structure that is able to expand and contract to change an interior volume within the resilient cylindrical flexure portion, a central passageway within the resilient cylindrical flexure, and a collection chamber connected to the central passageway. Also, a system including a reservoir, a plunger head located within the reservoir, a plunger arm connected to the plunger head, a driving shaft connected to the plunger arm, and a motor connected to the driving shaft, the motor controllable to move the drive shaft in a first motion and a second motion so as to move the advance plunger head and retract the plunger head within the reservoir.
