Problems solved by technology

[0006] However, in the case of bag-shaped receptacles, since they are used in medical science for other purposes, such as for infusion purposes, it is not possible to connect them to dialysis machines of the above-mentioned type, and complex processing is required.

Embodiment Construction

[0039] figure 1 A first preferred embodiment of the device according to the invention comprising a flexible receptacle or bag 1 surrounding a cavity 2 is shown. The cavity 2 is completely or partly filled with an active substance 3 which usually has a granular consistency or is present in powder form. The skin layer of the bag 1 is a flexible shell 4 surrounding the cavity 2 which expands like a balloon or a hose depending on the volume. The outer shell 4 is supported by an inner (cylindrical) support element 5 connected to the flexible outer shell 4 near its first axial end and near its second axial end. A first end of the support element 5 extends through the housing 4 such that the protruding portion of the support element 5 acts as an inlet 6 for a solvent 7 into the cavity 2 of the device. The second end of the support element 5 also extends through the flexible housing 4 such that this protruding portion of the support element 5 acts as an outlet 8 for the prepared sol...

Abstract

Devices for preparing a liquid solution are disclosed. The device includes a receptacle defining a cavity for receiving at least one active substance to be dissolved, at least one inlet leading into the cavity for feeding at least one solvent into the cavity, and at least one outlet leading out of the cavity for discharging the liquid solution including the at least one active substance and the at least one solvent from the cavity. The cavity or the receptacle may include a flexible outer shell for enclosing the cavity and an inner, preferably columnar, supporting element for stretching the flexible outer shell between at least two points, the supporting element comprising the at least one inlet at its first end and the at least one outlet at its second end and being enclosed by the flexible outer shell to provide an axially rigid cartridge that can be used in currently customary dialysis machines comprising cartridge connection systems, which can be produced at low cost.

Description

technical field [0001] The invention relates to a device for preparing a solution according to the preamble of claim 1 , which is particularly suitable for use in or on an extracorporeal blood treatment machine, such as a dialysis machine. Background technique [0002] In a dialysis machine, dialysate is prepared by adding liquid to dissolve salt (bicarbonate) stored in a cartridge or to dilute a liquid concentrate stored in a cartridge. Here, the cartridge is clamped from the outside in a special cartridge holder of the machine, via which the contents of the cartridge are tapped as required. This means that the cartridge holder generally has to fulfill two functions: supporting the cartridge and venting the contents of the cartridge. [0003] current technology [0004] A cartridge holder for a dialysis machine is known from the prior art (for example from DE 198 52 982 C1), said cartridge holder comprising a lower chuck / clamping jaw and an upper chuck / clamping jaw, Thes...
