Abstract: An auto-injector assembly comprises a medicament container defining a substantially cylindrical chamber containing a liquid medicament. A proximal end of the chamber is closed by a piston and a distal end of the chamber is closed by a seal spanning an opening. A biasing means, such as a spring, is coupled to the piston and acts to bias the piston towards the seal, thereby pressurizing the liquid medicament. The assembly also comprises a hypodermic needle and a removable needle cap for maintaining the hypodermic needle in sterile conditions until use. A means for establishes fluid communication between the chamber and the hypodermic needle such that the pressurized liquid medicament is automatically delivered through the hypodermic needle when communication has been established.

Abstract: A hand-held pre-filled syringe assembly comprises a syringe barrel, a piston slidably located within the syringe barrel, biasing means coupled to the piston and acting to bias the piston within the syringe barrel, a hypodermic needle, and an openable closure having an inlet and an outlet disposed between the syringe barrel and the hypodermic needle. The inlet of the openable closure is removably coupled to a nozzle of the syringe barrel by a first coupling and the outlet of the openable closure is coupled to a proximal end of the hypodermic needle by a second coupling. The openable closure defines a through-channel extending between the inlet and the outlet that is closed by a normally-closed valve. The syringe assembly contains a liquid medicament retained within the syringe barrel under pressure applied by the piston such that the liquid medicament is delivered through the hypodermic needle when the normally-closed valve is opened.

Abstract: An atomizer, a reservoir and a method are proposed for the delivery and in particular, the atomization of a formulation, particularly a powder. A pump and a spring are arranged inside the annular reservoir, the pump and the spring being moveable radially and in a sliding manner. The pump is actuated by the spring to put air under pressure for discharging powder from the reservoir. The reservoir comprises receptacles or cavities, each of which has an insert with a respective dose of the formulation. The receptacles are constructed as separate parts and/or arranged on a common or annular carrier and/or are sealed separately and/or on its outer circumferential periphery. The spring is tensioned and the air is sucked into the pump. Then, the next receptacle and a connecting element are aligned relative to each other. Finally, the aligned receptacle is pierced by the connecting element for supplying the air.

Abstract: A dispensing device, a storage device and a method for dispensing powder in which powder is dispensed through a duct with a flat cross section to de-agglomerate the powder and to generate a spray with fine particle size. A storage chamber for the powder may be closed by a bursting element which is burst by pressurized gas for discharging the powder, the gas pressure reaching or exceeding a peak value before the bursting element bursts so that the powder is dispensed at a lower gas pressure.
