Abstract: A centering interface is arranged between a tubular element mounted in a device, specifically a receiving tube or quiver, for a suction rod of a dialysis machine, and a movable element preferably guided pivotally about an axis, specifically a front plate of the dialysis machine. Centering surfaces are mated between the tubular element mounted in the device and the movable element. When a preferably sealed joint of the interface is manufactured, the tubular element mounted in the device can be moved in the axial direction against the force of a biasing spring during the movement of the movable element and the accompanying approach of the centering surfaces, while its guiding support allows a movement that permits the centering surfaces to be brought into the joining position with centering surface axes aligned with each other free of constraint forces.

Abstract: A medical connector link for establishing a fluid connection between two fluid lines includes a first male link element/connector element and a second female link element/connector element. The male link element is arranged or arrangeable in the female link element such that a fluid passage of the male link element and a fluid passage of the female link element form a common fluid passage. The connector link further includes a seal element arranged within a circumferential groove on an outer side of the male link element or on an inner side of the female link element. The seal element seals a radial gap between the female link element and the male link element. The male link element and/or the female link element have at least one recess that fluidically connects the common fluid passage with the circumferential groove.

Abstract: A device for anchoring a flexible line includes a base having an indentation that receives a portion of the line and a cover. The base defines a cavity curved at a first site in a first direction to prevent or limit the line from sliding out of the indentation. The cover releases the indentation for insertion of the line when the cover is in an open position, and covers the indentation when in a closed position to prevent or limit the received portion of the line from sliding out of the indentation. The cover has a receptacle portion which, in a closed position, is arranged at one end of the indentation and extends the cavity so that the cavity is curved in a region of the receptacle portion at a second site in a second direction running transversely or in a direction opposite to the first direction.
