Patent number: 12186463Abstract: The present invention refers to a container comprising a connection portion allowing for an easy, efficient and more hygienic connection of the container to a fluid dosing unit of a blood treatment device. According to the present invention the fluid dosing unit comprises a valve that fluidically closes the fluid dosing unit if no container is connected to the fluid dosing unit and that opens the fluid dosing unit upon connection of a container to the fluid dosing unit. Thus, undesired spillages potentially arising upon disconnection of the container from the fluid dosing unit can be avoided.Type: GrantFiled: September 10, 2020Date of Patent: January 7, 2025Assignee: FRESENIUS MEDICAL CARE DEUTSCHLAND GMBHInventors: Winfried Brehm, Philippe Laffay, Gerhard Wiesen

Patent number: 11890444Abstract: The invention relates to a connector (1) constituted by: base provided with a tubular wall (13) closed by a bottom wall (11) provided with at least one through-opening (111); a membrane provided with a flexible wall (23) having a central opening, a tubing (22) placed in the opening of the flexible wall; sealing means for preventing a liquid from leaving the connector through the tubing. The base and the membrane are fixed to each other in a liquid-tight manner. The flexible wall allows axial displacement of the tubing so that it can be moved between a closed position, in which a liquid cannot leave the connector through the conduit of the tubing, and an open position, in which a liquid from can leave the connector through the tubing. Retaining means (121, 222a) maintain the tubing (22) closed with a force that can be overcome manually to open it.Type: GrantFiled: November 4, 2019Date of Patent: February 6, 2024Assignee: FRESENIUS MEDICAL CARE DEUTSCHLAND GMBHInventors: Joanna Charre, Francois Dumont D'Ayot, Philippe Laffay
