摘要： A coupling member for a closed fluid transfer system includes a housing having a fluid connection and a coupling side. A first channel extends from the fluid connection toward the coupling side for fluidly connecting the fluid connection and the coupling side. An elastomer member surrounds an opening of the first channel, or forms a second channel adjoining the first channel. An elastomer member opening of the second channel is parallel to the longitudinal axis of the housing. The sealing surface is formed between a first position, in which the sealing surface seals the opening or the elastomer member opening of the second channel, and a second position, in which the sealing surface exposes the opening of the first channel or the elastomer member opening of the second channel for fluid communication with the coupling side.

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 cannula attachment for a spinal cannula that can be used, for example, in spinal anesthesia. The cannula attachment has a body that extends between a proximal end and a distal end, a fluid channel that extends through the body, and an observation channel section visible from the outside through a transparent region of the body. At least one optical lens is arranged in the transparent region by which the observation channel section is visible with optical magnification. The observation channel section contains at least one optical prism configured for refraction and/or reflection of light incident into the observation channel section through the optical lens.

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 pair of coupling members for a joint closed fluid transfer system. Each coupling member of the pair of coupling members includes a coupling housing having a longitudinal axis, a fluid connection, and a coupling side. A sealing member receptacle, which is arranged in the coupling housing, includes at least one fluid-tight chamber formed by at least one sealing member arranged in the sealing member receptacle. A spike in the coupling housing in a spike receptacle, in particular a spike arranged eccentrically in the coupling housing, fluidly communicates with the fluid connection. In a first embodiment, the coupling members are each complementary to one another, in particular identical in construction, and are connectable without an adapter by a relative angular offset about their longitudinal axis, preferably by a relative angular offset of 90°.

摘要： An adapter for coupling with medical vials has a housing with a center longitudinal axis. The adapter includes first latching portions on an inner circumference for latching to a first closing cover of a first vial, and second latching portions on the inner circumference for latching to a second closing cover of a second vial. The second closing cover has a larger diameter than the first closing cover. The housing has web portions and spring arm portions extending between the web portions and on which the first latching portions are arranged. The housing is elastically deformable from a first state, in which the spring arm portions latch with the first latching cover, into a second state, in which the spring arm portions allow a latching connection between the second latching portions and the second closing cover. The adapter device can be used in infusion therapy.

摘要： A closed system transfer device includes a first adaptor and a second adaptor that attach with one another in a coupled state to form a sealed fluid passage between two reservoirs. The first adaptor can be attached to a first reservoir, and the second adaptor can be attached to a second reservoir. One or both adaptors can include a septum that engages another septum during coupling and decoupling to prevent liquid or vapor from being released to the environment. The device can also include a vent line that equalizes pressure between the two reservoirs. The vent line can include at least one filter to filter gas in device. In addition, or in the alternative, the vent line can be connected in fluid communication with an inflatable membrane that stores gas inside the device and assists in equalizing pressure.
