Description

ABSTRACT:
A device for filtering a parenteral solution immediately before it is infused into a patient's vein. The device has a hollow housing containing a "depth" filter membrane of nonfibrous hydrophobic material having randomly connected stacked passages of from 10 to 40 micron size through the filter. After the filter membrane has had one surface in contact with the parenteral solution for a period of 15 to 60 seconds while passing only a minute amount of liquid it is then manually tapped to send a shock wave through the filter. This shock wave unexpectedly causes the hydrophobic filter to freely pass liquid and filter out more than 90 percent of all particulate matter of 5 micron size and larger from the parenteral solution. The large pore hydrophobic filter membrane can perform these filtering efficiencies with a very small, thin disc-shaped membrane of approximately 1/4 inch effective diameter.
