Abstract
Abstract A collapsible disposable container for dilution and delivery of chemicals for in vivo use which includes a combination adsorbent and absolute filter for effecting sterilization and removal of endotoxins and organic contaminants from a diluent introduced into the container prior to in vivo use thereof. Such combination may be in the container inlet, container outlet or in the main storage portion thereof. Unsterilized diluent can be employed for diluting chemicals in the container.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
163 words
A device for dilution and delivery of diluted chemicals for in vivo use, comprising: a disposable, collapsible flexible container for dilution and delivery of diluted chemicals for in vivo use, said container having an inlet means at one end and an outlet means at a second opposite end; a cartridge having an inlet end and an outlet end, an adsorbent for adsorbing contaminants in said cartridge adjacent said inlet end, an absolute filter having a pore size of no greater than 0.45μ in said cartridge adjacent said outlet end, said outlet end of said cartridge being attached to said inlet means of said container, whereby unsterilized diluent can be introduced into the container by passing through the inlet end of the cartridge, the adsorbent, the absolute filter and the inlet means of the container for effecting sterilization and removal of endotoxins and organic contaminants from the diluent and diluted chemicals delivered from the container through the outlet means thereof for in vivo use.
Claim 2
Independent Claim
163 words
A device for dilution and delivery of diluted chemicals for in vivo use, comprising: a disposable, collapsible flexible container for dilution and delivery of diluted chemicals for in vivo use, said container having an inlet means at one end and an outlet means at a second opposite end; a cartridge having an inlet end and an outlet end, an adsorbent for adsorbing contaminants in said cartridge adjacent said inlet end, an absolute filter having a pore size of no greater than 0.45μ in said cartridge adjacent said outlet end, said outlet end of said cartridge being attached to said inlet means of said container, whereby unsterilized diluent can be introduced into the container by passing through the inlet end of the cartridge, the adsorbent, the absolute filter and the inlet means of the container for effecting sterilization and removal of endotoxins and organic contaminants from the diluent and diluted chemicals delivered from the container through the outlet means thereof for in vivo use.
Claim 3
Dependent Claim
26 words
The device of claim 1 wherein the container further includes the chemicals to be diluted whereby the chemicals are stored in the container in undiluted form.
Claim 4
Dependent Claim
20 words
The device of claim 2 wherein said chemicals are chemicals which in a diluted state are suited for peritoneal dialysis.
Claim 5
Dependent Claim
13 words
The device of claim 3 wherein the adsorbent is comprised of activated charcoal.
Claim 6
Dependent Claim
17 words
The device of claim 4 wherein the absolute filter has a pore size from 0.1 to 0.25μ.
Claim 7
Independent Claim
168 words
A device for dilution and delivery of diluted chemicals for in vivo use, comprising: a disposable, collapsible flexible container for dilution and delivery of diluted chemicals for in vivo use, said container including an inlet means at one end and an outlet means at a second opposite end; a cartridge having an inlet end and an outlet end, an adsorbent for adsorbing contaminants with said cartridge adjacent said inlet end and an absolute filter having a pore size of no greater than 0.45μ within said cartridge adjacent said outlet end, said inlet end of said cartridge being attached to said outlet means of said container, whereby unsterilized diluent can be introduced into the container through the inlet means for dilution of chemicals therein and the diluted chemicals pass from the outlet means of the container through the adsorbent and absolute filter in said cartridge for effecting sterilization and removal of endotoxins and organic contaminants prior to in vivo use by delivery from the outlet end of the cartridge.
Claim 8
Independent Claim
168 words
A device for dilution and delivery of diluted chemicals for in vivo use, comprising: a disposable, collapsible flexible container for dilution and delivery of diluted chemicals for in vivo use, said container including an inlet means at one end and an outlet means at a second opposite end; a cartridge having an inlet end and an outlet end, an adsorbent for adsorbing contaminants with said cartridge adjacent said inlet end and an absolute filter having a pore size of no greater than 0.45μ within said cartridge adjacent said outlet end, said inlet end of said cartridge being attached to said outlet means of said container, whereby unsterilized diluent can be introduced into the container through the inlet means for dilution of chemicals therein and the diluted chemicals pass from the outlet means of the container through the adsorbent and absolute filter in said cartridge for effecting sterilization and removal of endotoxins and organic contaminants prior to in vivo use by delivery from the outlet end of the cartridge.
Claim 9
Dependent Claim
26 words
The device of claim 6 wherein the container further includes the chemicals to be diluted whereby the chemicals are stored in the container in undiluted form.
Claim 10
Dependent Claim
20 words
