POWERED STERILE SOLUTION DEVICE
The disclosure below relates to apparatus and methods for producing medicament using sub-optimal water sources. One embodiment of the disclosure is directed to an apparatus comprising a preliminary purification component, a disinfection component, a pharmaceutical grade water preparation (PGW) component, and a drug pack. Another disclosed embodiment relates to a method for producing a peritoneal dialysis solution, comprising, passing diluent through a preliminary purification component, passing diluent through a disinfection component, passing diluent through a PGW preparation component, passing diluent through a drug pack, and collecting solute produced by the drug pack.
1 . A method for producing a peritoneal dialysis solution, comprising:
passing a diluent through a preliminary purification component;
passing the diluent through a disinfection component;
passing the diluent through a PGW preparation component;
passing the diluent through a drug pack; and
collecting solute produced by the drug pack.
2 . The method of claim 1 , wherein passing diluent through the drug pack comprises: passing diluent through a dry reagent bed, thereby consuming reagents in the bed; carrying the consumed reagents with the diluent out of the bed; and compacting the reagent bed as the reagents are consumed.
3 . The method of claim 1 , wherein passing diluent comprises introducing a diluent to a reagent cartridge housing inlet.
4 . The method of claim 2 , wherein compacting the reagent bed comprises exerting pressure upon the reagent bed from two opposite directions.
5 . The method of claim 2 , wherein compacting the reagent bed comprises expanding a compression component adjacent the bed as the reagents are consumed.
6 . The method of claim 5 , wherein the compression component comprises a compressed elastic member continually exerting pressure upon the reagent bed.
7 . The method of claim 5 , wherein the compression component comprises an open-celled foam, and the diluent passes through the compression component.
8 . The method of claim 2 , wherein the disinfection component comprises a UV disinfection component.
9 . The method of claim 2 , wherein the diluent passes sequentially in order through the preliminary purification component, disinfection component, PGW preparation component, and drug pack.
10 . A self-contained apparatus for purifying water and delivering reagent in a fluid form, comprising:
a UV disinfection unit;
a filtration water pack, connected downstream from the UV disinfection device; and
a flow-through drug delivery device comprising a dry reagent bed in a fluid flow path, the flow-through drug delivery device being connected downstream of the filtration water pack.
11 . The self-contained apparatus of claim 10 , wherein the drug delivery component comprises a compression component configured to compact the dry reagent bed during erosion as fluid flows therethrough.
12 . The self-contained apparatus of claim 10 , further comprising a pump and preliminary filtration component upstream of said UV disinfection unit.
