摘要： A medical fluid transfer apparatus for transferring hazardous liquid medication in a fluid-tight manner. The apparatus includes a first connector portion having a first passage for fluid-tight connection to a medical syringe; a second connector portion having a second passage for fluid-tight connection to a medical liquid reservoir; a fluid channel extending between the first passage and the second passage, which permits a fluid-conducting transfer of the medication liquid between the syringe and the liquid reservoir; and an equalization container having an equalization volume, which is connected to the liquid reservoir in a fluid-conducting manner, and which is designed to receive a gas volume displaced during transfer of the medication liquid out of the liquid reservoir. The first passage and the second passage are connected to each other in a fluid-conducting manner via the equalization volume, which forms a fluid channel portion of the fluid channel.

摘要： A coupling member for a closed fluid transfer system includes a housing having a fluid connection and a coupling side. The housing includes a longitudinal axis extending from the fluid connection toward the coupling side and a spike having a fluid opening. The fluid opening is arranged in an end portion of the spike facing the coupling side. A sealing member receptacle is arranged in the housing on the coupling side, and a sealing member is arranged in the sealing member receptacle. The housing includes a housing portion that at least partially surrounds the sealing member receptacle and a threaded portion. The coupling housing with the sealing member is guided by a guiding structure and movable in the direction of the longitudinal axis via the threaded portion between a position with maximum distance to the fluid connection and a position with minimum distance to the fluid connection.

摘要： A coupling system for a closed fluid transfer system includes a coupling member that features a coupling member housing. The coupling member housing includes a housing portion that at least partially surrounds a sealing member receptacle in an axial direction with respect to the longitudinal axis and which includes a coupling member housing threaded portion on the inner surface facing the sealing member. The coupling system also includes a mating coupling member for coupling with the coupling member. The mating coupling member includes a mating coupling member housing that has a mating coupling member guiding structure. The coupling member housing threaded portion of the coupling member is configured such that the mating coupling member guiding structure and the sealing member receptacle structure are jointly and movably guided, in particular in a predetermined positional relation to each other, by the coupling member housing threaded portion.

摘要： A fluid transfer device for use in medical/pharmacological applications a method of use, and a closed medicine transfer system. The fluid transfer device includes a first adapter unit having a first sealing element and a second adapter unit having a second sealing element. The first adapter unit and second adapter unit, when connected, provide a fluid connection between the first adapter unit and the second adapter unit and prevent, when disconnected, the transfer of fluid out of the first adapter unit and the second adapter unit. A fluid connection between the first adapter unit and second adapter unit is established by a combined pressing movement towards one another and a rotational movement with respect to one another, only after a constant pressure has been set which the first sealing element and the second sealing element apply against each other.
