Abstract
An apparatus and method is disclosed for treating blood, by having the blood enter a container, in which essentially insoluble fats (or lipids) are discriminately withdrawn out of the blood as the blood flows through or rises in the container, preferably by means of a wick that is in the container, as the level of blood in the container rises around the wick, such that essentially insoluble lipids on the upper surface of the rising blood are removed from the blood, leaving behind essentially aqueous components of the blood. Clots, bone chips and the like are also removed from the blood by means of a filter.
Claims9
A method of treating blood of a patient for re-use, comprising the steps of:
- (a) providing a container for receiving blood from a body of the patient;
- (b) delivering the patient's blood to the container;
- and
- (c) removing essentially insoluble lipids from the blood in the container by contacting the blood with a lipophilic discriminating means, that discriminates between essentially insoluble lipids in the blood and essentially aqueous components of the blood that includes soluble lipids, and accumulating the essentially insoluble lipids separately from the essentially aqueous components of the blood that include soluble lipids by discriminating between said essentially insoluble lipids and said essentially aqueous components of the blood that include soluble lipids.
A method of treating blood of a patient for reuse, comprising the steps of:
- (a) providing a container for receiving blood from a body of the patient;
- (b) delivering the patient's blood to the container;
- and
- (c) removing essentially insoluble lipids from the blood in the container by contacting the blood with a lipophilic discriminating means that discriminates between essentially insoluble lipids in the blood and essentially aqueous components of the blood, and accumulating the essentially insoluble lipids;
- (d) wherein the contacting of the blood with the discriminating means includes contacting the blood with a wicking means and wicking insoluble lipids from the blood.

- (d) wherein the contacting of the blood with the discriminating means includes contacting the blood with the discriminating means having a pore size of up to 250 microns.
