  • Publication number: 20130023833
    Abstract: An attachment part with a coupling part by means of which coupling part the attachment part can be attached to a dispensing unit. The coupling part has a female cone area, with a continuous inlet opening, and a locking structure arranged around the female cone area. The female cone area can be pushed onto a male cone area of the dispensing unit, in order thereby to connect the attachment part to the dispensing unit. The locking structure serves to secure the attachment part on the dispensing unit. The first coupling part additionally has a rotation element, which is rotatable concentrically about the female cone area and on which the first locking structure is formed. The rotation element has an actuating element, which serves to rotate the rotation element relative to the female cone area.

  • Publication number: 20120330229
    Abstract: The invention relates to a syringe-like mixing device, comprising a housing, in which a mixing chamber is formed, a piston, which can be slid in the mixing chamber from the proximal side, and a mixing element, which can be operated from the distal side. In order to ensure simple operation, the mixing device has a sealing cap, which seals the distal open end of the mixing chamber and which has a passage opening, through which an operating rod for the mixing element is guided. The sealing cap can be completely removed from the housing together with the operating rod and the mixing element. In order to discharge the mixing product, a second sealing cap can be placed onto the housing. Accessory parts can be connected to said second sealing cap. The mixing product can then be discharged as with a conventional injection syringe.

  • Publication number: 20120316509
    Abstract: The invention relates to a discharge device for discharging a fluid product, for example, in the form of a syringe. The discharge device comprises a housing (1), which bounds a reservoir (16), and a piston (23), which is slidably arranged in the housing (1) in a longitudinal direction in order to discharge the fluid product distally from the reservoir (16) through an outlet opening (13). A window opening (15) is formed in a circumferential side wall (11) of the housing (1). An insert element (3) is inserted into said window opening (15) perpendicularly to the longitudinal direction. The insert element (3) protrudes into the reservoir (16). In this way, a motion of the piston (23) can be limited in the proximal direction in order to prevent the piston (23) from falling out, and the metering of the fluid product can be made easier in that the insert element (3) establishes a detachable locking connection with an advancing element (27) for the piston (23).

  • Publication number: 20120302986
    Abstract: The invention relates to a device for removing a fluid from at least one container (300), from a vial for example, said container being closed by a closure (320) that can be punctured. The device comprises a base body (271) with a container receiving portion (272) and a hollow needle-like puncturing organ (277) in order to puncture the closure (320) of the container (300) in a removal position of the container (300). The aim of the invention is to enable mounting the container on the device without unintentionally puncturing the closure. This is achieved in that detent structures (274, 275) are provided which retain the container (300) on the device in a removal position and in a mounting position which is different from said removal position. Such a device can be used in particular to fill an applicator (280) with one or more fluid reservoirs from one or more vitals.

  • Publication number: 20120298254
    Abstract: The invention relates to a device for removing a fluid from at least one container (300), for example, from a vial, that has a seal that can be punctured. The device comprises a base body (210), in which a fluid channel is formed. In order to reduce the lost volume, a pin-shaped insertion element (250) that reduces the cross-section of the fluid channel is inserted into the fluid channel through an insertion opening. Locking structures (262, 263) that retain the container on the device in a removal position and in a storage position different therefrom can be provided so that the container can be stored on the device without the seal being punctured accidentally. Such a device can be used in particular to fill an applicator (100) having one or more fluid reservoirs from one or more vials.

  • Patent number: 8256646
    Abstract: A device for storing, mixing, and dispensing components that has at least one container and a transferor configured to transfer a first, liquid component into a second, powdery component, a dispensing piston configured to dispense mixed materials, a valve assembly arranged between the first, liquid component and the second, powdery component, and a closure element. The first, liquid component and the second, powdery component are located in the at least one container, and the transfer device arranged between the first, liquid component and the second, powdery component is designed as a sealing passage piston. Such a multicomponent syringe has a significantly reduced volume as compared to the multicomponent syringes of the prior art but nevertheless offers a simple and safe handling besides the required safety with regard to separate storage and hygiene.
