  • Convertible fluid feed system with comformable reservoir and methods
    Patent number: 7195011
    Abstract: A feed system for an aerosolizer utilizes an ampoule containing a liquid and includes a housing having an ampoule region into which the ampoule is held, and a liquid receiving region that is adapted to receive liquid dispensed from the ampoule. An interface is used to couple the liquid receiving region to an aerosol generator, whereby liquid from the liquid receiving region is permitted to flow to the aerosol generator for aerosolization.
    Type: Grant

  • Syringe for medicinal purposes
    Patent number: 5803918
    Abstract: The syringe for medicinal purposes features a syringe barrel (1), one end of which is formed as an adapter (2) for a cannula or a closure (3), e.g., in the form of a tip cap, and of a plunger (4), arranged within the syringe barrel (1), and movable by a piston rod (5). At the end of the syringe barrel (1) facing away from the adapter (2), a plunger brake (6) is arranged, which is formed by a rest piece surrounding the syringe barrel (1) and connected removably to it. The rest piece has a projection extending into the lumen of the syringe barrel (1), which forms a stop for the side of the plunger (4) away from the adapter (2).

  • Blood pump for pulsating operation
    Patent number: 5263978
    Abstract: A blood pump housing (43) accommodates at least one piston (21a,21b) driven by a coupling point (19a,19b) on a triangular closed hypocycloidal path (Z.sub.a, Z.sub.b). The piston (21a,21b) is provided for periodically pressing and releasing a blood chamber (37a,37b). One of the corners of the triangular closed hypocycloidal path (Z.sub.a,Z.sub.b) is directed towards the piston (21a,21b), so that the piston movements substantially consist of three periods, i.e. an advance stroke period, a return stroke period and a stationary stroke period.
