Embodiment Construction

[0081] An exemplary embodiment of the present invention will now be described with reference to a package, which is manufactured by evacuation and used to prepare dialysate. However, it should be understood that the technology to be described is not limited to such implementations and applications, but alternative manufacturing methods can be used and the technology can be used to prepare any type of medical solution.

[0082] Throughout the description, the same reference numerals are used to identify corresponding elements.

[0083] Figure 1(a) and Figure 1(b) are respectively a side view and a plan view of a package or bag 1, which contains the powder material used in the preparation of dialysate or concentrate to be further diluted into The spare parts for dialysate are collectively referred to as dialysate hereinafter. The combined storage and preparation package 1 is shown in a transport / storage state, that is, in a state before the dialysate is prepared. The powder materia...

Abstract

A package has a transport / storage state for storing powdery material which is to be mixed with a solvent to form a medical solution, e.g. for use in dialysis treatment. The package comprises a compartment (6) which is at least partially defined by two opposing wall portions, and a connector (10). In the transport / storage state, the compartment contains the powdery material in the form of at least two distinct sets (2A-2D) of powdery material of different compositions, where the opposing wall portions are brought into engagement with the powdery material so as to immobilize the sets of powdery material (2A-2D). When used for preparation of the medical solution, a fluid is selectively admitted into the package via the connector (10) so as to expand the compartment (6) and enable mixing of the sets (2A-2D) of powdery material with the solvent in the compartment (6).

Description

Technical field [0001] The present invention relates to a technique for preparing medical solutions from powdered materials, and in particular to packages for storing such powdered materials. Background technique [0002] One type of treatment for patients with significantly impaired kidney function or renal failure is called "dialysis." Hemodialysis ("hemodialysis") or peritoneal dialysis (PD) can be used. Both of these methods essentially involve removing toxins from body fluids and restoring the body fluids by means of diffusion and / or convection of the dialysis solution. [0003] Patients receiving hemodialysis usually use 75 to 200 liters of prepared dialysate three times a week. The largest component of these solutions is water. [0004] Conventionally, the dialysate used for hemodialysis is prepared from a single concentrated solution. For example, a concentrated preparation A includes a mixture of various salts, sugars, and acids dissolved in water. Another concentrated ...
