Abstract: A coupling device (100) for transferring a fluid is provided. The coupling device comprises a first housing (110), a tube portion (140) projecting into the first housing, and a second housing (200) displaceably arranged within the first housing. A third housing (300) is releasably connectable to the second housing and displaceably arranged within the first housing when connected to the second housing. Control element(s) are configured to conditionally seal first and/or second sealing elements when the second housing and the third housing are connected. In a first position of the second housing, the tube portion and the channel are sealingly separated by the first and second sealing elements when the second housing and the third housing are connected. In a second position of the second housing, the tube portion projects through the first and second sealing elements for enabling a transfer of fluid through the coupling device.

Abstract: A coupling system for fluid transfer and a system for transferring fluids into a patient are provided. The coupling system comprising a first tube, at least one second tube, a coupling device configured for a connection of the at least one second tube with the first tube, wherein the coupling device comprises at least one first connector element and at least one second connector element configured to matingly connect for a connection between the at least one second tube and the first tube, wherein the first connector element comprises a first sealing element and a tube portion, and wherein the second connector element comprises a second sealing element, whereby in a connected state of the coupling device, the tube portion projects through the first and second sealing elements for enabling a transfer of fluid through the coupling device.

Abstract: A coupling device (100) for transferring a fluid is provided. The coupling device comprises a first housing (110), a tube (140) and a first sealing element (220). The coupling device further comprises a second housing (300) comprising a channel (310) and a second scaling element (320). At a first and second stage of a connection of the coupling device, the first and second sealing elements, of which at least one comprises an antimicrobial coating, are configured to abut each other and sealingly separate the tube and the channel, whereafter the tube projects through the first and second sealing elements for enabling a transfer through the coupling device. At a first and second stage of a disconnection of the coupling device, first (400) and second spaces (410) are respectively defined for enclosing the fluid, whereby the fluid is arranged to come into contact with the antimicrobial coating.
