Abstract: The invention relates to a method and a device for lyophilizing, reconstituting and administering a reconstituted substance. The device has an elongate housing having a dispensing-side front housing end and a housing end lying opposite it. A first chamber, containing a lyophilizate, is disposed in the housing in the region of the front housing end and is tightly sealed at an end facing the front housing end by a removable closure and is tightly sealed in the direction of the rear housing end by a plunger. A second chamber is provided or formed in the housing in the region of the rear housing end which is connected by at least one opening to the ambient atmosphere. This opening is closed by a membrane which is permeable to gas but not to bacteria.

Abstract: The invention relates to an injection device (1), which comprises a support housing (2), an activating sleeve (9), a cartridge (3) containing a medicine (14), a first drive unit (4), a safety device (5), a needle arrangement (6), a needle protection element (7) and a second triggerable drive unit (8), whereby the latter moves the needle protection element (7) from the non-effective position into the position covering one needle end (21) of a cannula (20). The support housing (2) is surrounded over most of its longitudinal extension between its distal and proximal end (11, 12) by the activating sleeve (9), whereby the needle protection element (7) with the second drive unit (8) cooperating therewith is arranged radially between the support housing (2) and the activating sleeve (9), as viewed in axial cross section.

Abstract: The syringe is intended for one-off use and has a syringe barrel (1), a barrel stopper (12) which can be displaced in the syringe barrel (1) by means of a plunger rod (11) and a needle unit (25) accommodated in the syringe barrel (1). The plunger rod (11) and the needle unit (25) are connected to one another by coupling means (20, 40) in order to retract the needle unit (25) into the syringe barrel (1) after the injection. As proposed by the invention, the needle unit (25) comprises a needle holder (26) made from plastic surrounding an injection needle (27) made from stainless steel along part of its length, which is closed off from an interior of the syringe barrel (1) containing an injection solution (50) by means of a seal insert (36) made from pharmaceutical rubber through the injection needle (27) extends from the rear end. As a result of this feature, an injection solution (50) contained in the syringe is in contact exclusively with permitted materials and the syringe can therefore be stored pre-filled.
