A device for preparing a sterile liquid includes structure for validating a sterilization treatment applied to the liquid. The validating structure includes structure for calculating, from at least one operating parameter of the device, a parameter representing a sterilizing value for the sterilization treatment, and structure for comparing the calculated parameter to a threshold value corresponding to the sterility of the liquid.

Process and device for sterilizing and dispensing a liquid for medical use

Apparatus for the preparation of fluids intended for medical use is disclosed, including a water source and at least one cartridge or other vessel containing a solid such as a powder which is to be dissolved in the water for preparation of the desired fluid. The apparatus includes a container such that the water and a powder can be mixed and a concentrate provided in the container, and a recirculation circuit for recirculation of the water or concentrate solution into the container for further mixing of the water and powder to prepare a concentrate having a predetermined concentration.

System for the preparation of a fluid concentrate intended for medical

Methods for the central preparation and distribution of a concentrate to a plurality of medical treatment devices are disclosed comprising supplying a stream of substantially only water to a central container which includes a single salt composition at least partially in solid form, producing a substantially saturated solution of the salt composition in the central container, and distributing the salt solution to a distribution conduit which includes a plurality of concentrate connectors whereby the salt solution can be distributed to the plurality of medical treatment devices. Methods for disinfecting this apparatus, the apparatus itself, and containers for use in the apparatus are also disclosed.

A method for preparation of a medical solution from water and a plurality of concentrates, including at least one acid in gaseous form, comprises the steps of transporting the water from a source through a main conduit and successively adding the plurality of concentrates to the water in the main conduit at a plurality of predetermined points positioned along the main conduit.

Method for the preparation of a medical solution

A method and an apparatus for preparation of a medical solution from water and a plurality of concentrates, including at least one acid in gaseous form, comprises the steps of transporting the water from a source through a main conduit and successively adding the plurality of concentrates to the water in the main conduit at a plurality of predetermined points positioned along the main conduit. The apparatus for preparing the medical solution includes a source for supplying the gaseous acid and other concentrates to the plurality of predetermined points along the main conduit, wherein the plurality of predetermined points includes a gas inlet for injecting the acid in gaseous form supplied from the gas source into the main conduit.

Method and apparatus for the preparation of a medical solution

Apparatus for the preparation of fluids intended for medical use is disclosed, including a source of pure water and at least one cartridge or other vessel containing a powder which is to be dissolved in the water for preparation of the desired fluid. The apparatus includes a container such that the water and a powder or powder concentrate can be mixed and a concentrate provided in the container, and a recirculation circuit for recirculation of the water or concentrate solution into the container for further mixing of the water and powder or powder concentrate to prepare a concentrate having a predetermined concentration.

A system for preparing a fluid intended for a medical procedure substantially at the time of use by mixing of at least one concentrate in powder form with water. The system includes a reservoir for a source of water, at least one vessel containing a concentrate in powder form and a concentrate fluid circuit for withdrawing a small quantity of water from the reservoir and passing same through the vessel containing the concentrate in powder form in order to dissolve the concentrate to produce a concentrate fluid, and for then conducting the concentrate fluid to a primary fluid circuit communicating with the reservoir so that the produced concentrate fluid is mixed with the rest of the water withdrawn from the reservoir. In a preferred embodiment, the vessel comprises a self-contained cartridge containing a quantity of concentrate in powder form therein which is suitable for one treatment procedure. The system is intended in particular for the preparation of fluids for use in connection with medical procedures such as hemodialysis, hemodiafiltration and hemofiltration. However, it may also be used for the preparation of fluids for other medical procedures or treatments as well.
