Abstract
There are disclosed a container and a method of aspirating body liquids, that allow controlled capillary attraction to hold the liquid in place for storage, but not so tightly that the liquid cannot be aspirated away. A mass of compatible porous material is used in the container and comprises fibers with a controlled capillary attraction that supports a column of water that is between about 2 mm and about 60 mm in height.
Claims9
In combination, a liquid aspirator and a container for body liquids to be aspirated by said aspirator, said container comprising:
- a mass of compatible porous material that will absorb and be wetted by the body liquid of choice, and means for holding said mass of material, and any liquid contained therein, in a predetermined location, said mass of material comprising (a) fibers or fingers having a capillary attraction which will support a column of water that is between about 2 mm and about 60 mm in height, or (b) an open-cell foam having liquid attraction and liquid retention that is equivalent to that of said fibers.
A method of aspirating body liquids in an environment of reduced gravity, comprising
- injecting the liquid into a site portion of a mass of wettable liquid-compatible porous material that will absorb the body liquid, said mass of material comprising (a) fibers or fingers having a capillary attraction which will support a column of water that is between about 2 mm and about 60 mm in height, or (b) an open-cell foam having liquid attraction and liquid retention that is equivalent to that of said fibers;
- inserting the open end of an aspirator into said mass of porous material at said site portion in which the liquid resides,
- and creating a sufficient partial vacuum in the aspirator to draw at least some of the liquid out of the mass of material.
