Adapter () for connecting a receptacle connector to a connection socket of a dialysis machine, each provided with two fluid lines, whose ends are concentric on the connector and non-concentric and distant from each other on the socket. The adapter () has concentric first () and second () adapter ribs, the first forming a circular chamber open towards the outside, in the bottom of which a first orifice is produced, while the second forms an annular chamber open towards the outside, in the bottom of which a second orifice is produced. The adapter also has first and second connection channels () isolated from each other, in which the first and second orifices coming from the first and second annular chambers open out. Each channel () includes a connecting piece () consisting of a circular tube, for introduction into the reception elements of the coupling socket ().

Adapter for connecting a receptacle connector to a coupling socket of a dialysis machine

A self standing bag having two side wall sheets and a bottom sheet. To flatten the bag, the bottom sheet is sandwiched between the two side wall sheets and symmetrically folded along a line parallel to its bottom edge, separating the bag into a four-layer part and a two-layer part. In the two-layer part, the bag includes first sloped sealing lines extending between a first two points on the top edges of the side wall sheets and spaced from the vertical side wall edges by a first distance, to a second two points spaced from the vertical edges of the side wall sheets by a second distance less than the first distance. The four-layer part includes second sloped sealing lines extending between the second two points and a third two points on the bottom edges of the side wall sheets.

Container filled with a liquid concentrate for making dialysate

A device for putting in solution a powdery concentrate includes a liquid supply pipe (), an extraction pipe () with a valve (), and a transfer pipe () connected to a junction point, the transfer pipe being for connecting to a receptacle () containing the concentrate. The junction point is in the constriction of a venturi tube (), the supply pipe () being connected to the convergent chamber () and the extraction pipe () to the divergent chamber (). If the valve () is closed, the liquid leaves the venturi tube through the vacuum tapping to enter the receptacle. When the valve () is opened, the liquid leaves the venturi tube through the divergence chamber, causing a pressure drop in the vacuum tapping. The saturated liquid contained in the receptacle is then sucked and entrained by the liquid passing through the venturi.

Method and device for dissolving a solid concentrate

An insert for a receptacle intended to contain a concentrated product in solid or liquid form includes a main part () formed by a base () extended on the edge by a wall () perpendicular to the base, with an opening () formed in the base. A receptacle with such an insert is also provided. In order to enable emptying the receptacle entirely without leaving dead spaces in which the products to be solubilized may accumulate, the face of the base () intended to be in the receptacle after assembly is concave at the opening, so that the opening is at the bottom of a trough (). This avoids corners in which the liquid would not circulate sufficiently, and prevents solid product from accumulating elsewhere than in the trough, so that it is always subjected to the flow of liquid.
