Method and apparatus for the central preparation and distribution of salt concentrates

Apparatus for the central preparation and distribution of a concentrate to a plurality of medical treatment devices for performing a procedure selected from the group consisting of hemodialysis, hemofiltration and hemodiafiltration comprising central concentrate preparation means for preparing a substantially saturated solution from substantially only sodium chloride which is at least partially in solid form and a supply of substantially only water, inlet means for supplying said water to said central concentrate preparation means for preparing said concentrate, heating means for heating said concentrate during operation of said medical treatment device to an elevated temperature above about 60.degree. C., and conduit means for supplying said concentrate to a distribution conduit for distribution to said plurality of medical treatment devices, whereby simultaneous disinfection is also achieved during operation of said medical treatment device for performing a dialysis treatment.

A container for use in apparatus for the central preparation and distribution of a dialysis concentrate to a plurality of dialysis machines comprising central concentrate preparation means for preparing a substantially saturated salt solution of substantially only a single salt composition from said salt at least partially in solid form and a supply of water, inlet means for supplying said water to said central concentrate preparation means, and conduit means for supplying said salt solution to a distribution conduit for distribution to said plurality of dialysis machines, said container for incorporation into said central concentrate preparation means and including sodium chloride in particle form in a quantity of at least about 10 kg, said container including inlet means for said water and outlet means for said substantially saturated salt solution, said inlet means including first connecting means, and said outlet means including second connecting means, said first and second connecting means being compatible with each others whereby a dialysis fluid can be provided for use in said dialysis machines by dilution of said dialysis concentrate.

A method for the central preparation and distribution of a dialysis concentrate to a plurality of dialysis machines comprising supplying a liquid stream comprising substantially only water to a central container including substantially only sodium chloride at least partially in solid form in an amount of at least about 10 kg therein, producing a substantially saturated solution of said sodium chloride in said central container, adding a separate substance to said substantially saturated sodium chloride solution to obtain said concentrate, and distributing said concentrate to a distribution conduit, said distribution conduit including a plurality of concentrate connectors for distribution of said concentrate thereto, whereby a dialysis fluid can be provided for use in said dialysis machines by dilution of said dialysis concentrate.

A method for the central preparation and distribution of a dialysis concentrate to a plurality of dialysis machines comprising supplying a liquid stream comprising substantially only water to a central container including substantially only sodium chloride at least partially in solid form therein, producing a substantially saturated solution of said sodium chloride in said central container, diluting said substantially saturated sodium chloride solution with water, adding carbon dioxide gas to said diluted sodium chloride solution to form said concentrate, and distributing said concentrate to a distribution conduit, said distribution conduit including a plurality of concentrate connectors for connection to said plurality of dialysis machines for distribution of said concentrate thereto, whereby said dialysis fluid may be provided for use in said dialysis machine by dilution of said dialysis concentrate.

Apparatus for the central preparation and distribution of a dialysis concentrate to a plurality of dialysis machines comprising central concentrate preparation means for preparing a substantially saturated solution from substantially only sodium chloride which is at least partially in solid form in an amount of at least about 10 kg and a supply of substantially only water, inlet means for supplying said water to said central concentrate preparation means, metering means for metering an additional substance into said substantially saturated sodium chloride solution to form said concentrate, and conduit means for supplying said concentrate to a distribution conduit for distribution to said plurality of dialysis machines, whereby a dialysis fluid can be provided for use in said dialysis machines by dilution of said dialysis concentrate.
