摘要： A wearable drug delivery device and related methods are described. The wearable drug delivery device can include: a housing; a flexible bag disposed within the housing; a cannula in fluid communication with the flexible bag; and a pumping mechanism for forcing a drug from the flexible bag and into the cannula, wherein the pumping mechanism is proximate the flexible bag and includes a spring-loaded paddle or a driving bag.

摘要： An on-body injector includes a drug reservoir having an outlet. First and second pistons may be positioned within the reservoir, with the second piston first being moved to open the outlet, followed by the first piston being moved to convey a drug from the reservoir via the outlet. The reservoir may instead include a cover, with a valve positioned between the outlet and the cover. The valve is rotated to place a channel of the valve in fluid communication with a through-hole of the cover, allowing flow from the reservoir via the outlet. The reservoir may instead include a valve movable from a condition in which it deforms the outlet, preventing flow through the outlet, to a condition allowing flow. The reservoir may instead include a seal that is deformed by an increase in pressure within the reservoir, with the deformed seal being open to allow flow through the outlet.

摘要： A drug delivery device has a housing with an adhesive pad associated with the lower surface of the housing and configured to removably attach to a human body surface. A drug reservoir is positioned within the housing and includes an outlet with a valve, with a needle fluidically connected to the reservoir and configured to define at least a portion of a fluid flow path between the reservoir and the human body surface. A controller is configured to control the components of the drug delivery device to execute a drug delivery routine. The drug delivery device also includes pressurized fluid positioned to apply a force to the reservoir. The controller moves the valve from a closed condition to an open condition during a drug delivery routine to allow the pressurized fluid to deform the reservoir or move a plunger to convey the drug out of the reservoir via the outlet.

摘要： A drug delivery device has a housing with an adhesive pad associated with the lower surface of the housing and configured to removably attach to a human body surface. A deformable drug reservoir is positioned within the housing and includes an outlet, with a needle fluidically connected to the drug reservoir and configured to define at least a portion of a fluid flow path between the drug reservoir and said human body surface. A delivery assembly is associated with the drug reservoir and includes a roller and a drive assembly, with the drive assembly being controlled by the controller during a drug delivery routine to move the roller from a first position to a second position so as to cause the roller to contact and deform the reservoir, thereby conveying a drug from the reservoir via the outlet.

摘要： Described herein are wearable devices and methods for medicament delivery. Example devices can include a housing having an underside adapted to be proximate to a skin surface, and a reservoir disposed in the housing, the reservoir configured to be filled with a medicament to be delivered to the patient. The devices can include a cannula disposed within the housing and coupled to the reservoir, in which the cannula configured to protrude from a port defined by the housing to be positioned in the skin surface. The devices can further include a capacitive sensor configured to detect whether the medicament has leaked from the delivery device, in which the capacitive sensor includes a conductor disposed in a portion of the underside of the housing.
