Abstract
A method for removing aluminum from blood includes the step of adding to the blood an anticoagulant and a complexing agent for aluminum or one compound effective in both preventing coagulation of blood and capable of complexing aluminum. The complexing agent or compound capable of complexing aluminum is allowed to intermingle with the blood and complex with aluminum present in the blood. The complex of complexing agent and aluminum formed during the intermingle step is then separated using a semi-permeable membrane, and the blood is recovered. The method is particularly useful in treating patient's having aluminum intoxication.
Claims11
A method for treating a person having aluminum intoxication, comprising:
- leading a flow of blood along one side of a semipermeable membrane of a dialyzing filter and a flow of dialyzing fluid along a second side of said semipermeable membrane;
- mixing a non-dialyzable anti-coagulant and an aluminum ion complexing agent which complexes aluminum with said blood upstream of said dialyzing filter, said mixing step producing a mixture containing said blood, said non-dialyzable anticoagulant, said aluminum ion complexing agent and aluminum ion complexes formed from said aluminum ion complexing agent and aluminum ions present in said blood;
- passing said mixture through said dialyzing filter;
- and
- removing said aluminum ion complexes through said semipermeable membrane.
A method for removing aluminum from blood, comprising the steps of:
- adding an anticoagulant to blood;
- adding a complexing agent which complexes aluminum to said blood, wherein at least one of said anticoagulant and said complexing agent is a non-citrate compound;
- allowing said complexing agent to intermingle with said blood and complex with aluminum present in said blood;
- separating complexes of said complexing agent and said aluminum from said blood through a semipermeable membrane;
- and
- recovering said blood.
A method for removing aluminum from blood, comprising the steps of:
- adding at least one non-citrate compound to blood in an amount effective in preventing coagulation of blood and capable of complexing aluminum;
- allowing said at least one non-citrate compound to intermingle with said blood and complex with aluminum present in said blood;
- separating complexes of said at least one non-citrate compound being capable of complexing aluminum and aluminum present in said blood from said blood through a semi-permeable membrane;
- and
- recovering said blood.
