Abstract: A delivery system configured to be secured on a patient skin which comprises a first container having a first variable volume; a second container having a second variable volume; and a skin adherable unit configured to secure the first container and the second container to the patient skin. The medical device may further comprise a containers' interface configured to operatively couple the first container and the second container such that a volume increase of the second variable volume may induce a volume decrease of the first variable volume. Preferentially, the system further comprises a vent device configured to prevent any unintended pressure increase in the first storage compartment.

Abstract: In various embodiments, a drug pump includes a housing and, within the housing, an expandable drug reservoir at least part of which is exposed to a pressurized propellant. The propellant exerts a substantially constant pressure on the drug reservoir. A flow restrictor significantly limits outflow from the pump, and preferably has both a small diameter and a long path length, which acts to control the outflow from the drug reservoir. As a result, the pump produces a substantially constant outflow.

Abstract: A fluid dispensing device is provided for dispensing a measured amount of fluid into a living organism. The device includes a rigid fluid reservoir closed by a septum for use in a fluid dispensing device for dispensing a measured amount of fluid into a living organism, wherein the device has a main housing enclosing the operative components of the device, the said fluid reservoir located within the main housing, an injection assembly including a needle, and a trigger mechanism. The needle has a first end adapted to piercing the septum and pushing the septum into the reservoir so that the septum acts as a piston, expelling the fluid through the needle, and a second end adapted to injecting the fluid into the living organism.
