Self-pressurizing fluid deliver systems and devices and methods of using the same. An exemplary pressurized sterile fluid storage bag system referenced herein includes a foam cavity formed from a rigid, non-conforming material and an elastic, conforming material and containing a resilient open cell or closed cell foam with capabilities to restore form when compressed, an air valve, a fluid cavity formed from said elastic, conforming material on one side and a material which may be rigid and non-conforming or elastic and conforming, and a fluid valve.

A medicinal infusion system includes a safety valve for isolating residual medication by providing a single point of fluidic disconnect to encapsulate a residual fluid volume prone to spillage. The safety valve couples a medicinal repository such as an infusion pump to a medicinal supply, typically from a syringe or tubing. The safety valve includes a resilient, deformable, or hinged surface for isolating and sealing the medicinal flow to eliminate and/or isolate any residual volume in tubing and connectors. The isolating surface accommodates an inserted fitting or coupling for allowing the medicinal flow to fill the infusion pump. Upon disconnection, fluids on either side of the safety valve are therefore isolated on the respective fill or source sides, and residual volume prone to spillage is eliminated.

A device includes an inflatable balloon, a reservoir disposed within the inflatable balloon, a needle compartment attached to the balloon and to the reservoir, an injection needle disposed within the needle compartment, and an inflation mechanism. The reservoir contains a therapeutic preparation. The inflation mechanism is structured to inflate the balloon, and upon inflation, the injection needle is structured to enter the reservoir. A method includes making an autoinjector available to a subject with instructions to ingest the autoinjector. The autoinjector is structured to inject a therapeutic preparation into a wall of a gastrointestinal tract of the subject responsive to ingestion of the autoinjector. The autoinjector includes an injection needle disposed in a needle compartment attached to a reservoir. The injection needle is initially separated from the reservoir, and is structured to enter the reservoir for delivery of the fluid therapeutic preparation through the needle into the wall.

Processes and devices for delivering a fluid by decomposition of hydrogen peroxide are disclosed. Advantageously, the reaction is very fast and exothermic resulting in a fast ejection and, optionally, heating a fluid as it is ejected from a container. Also disclosed is a fluid flow system powered by a gas-generating reaction that is activated by an electrothermal activation switch.

The present disclosure relates to a medicament delivery device comprising a medicament receiving element, at least one fluid chamber having a fluid outlet configured to direct fluid vapour towards the medicament receiving element, a heating element for heating the fluid in the at least one fluid chamber. The device is configured such that, in use, the heating element heats the fluid in the at least one fluid chamber to at least partially evaporate the fluid so that the vapor pressure in the at least one fluid chamber increases until the fluid is expelled out of the at least one fluid chamber through the fluid outlet towards the medicament receiving element and entrains the medicament towards the patient's skin.
