Abstract
A disposable, flexible plastic filter pouch includes a top inlet opening for collection of blood, urine or other body fluids; a filter sheet for collecting and retaining solid materials such as kidney stones which may be contained in the fluids; and means for sealing the pouch after use to enable the solid sample collected to be sent to a laboratory for analysis with no need to place the solid material in another container and minimum exposure of hospital personnel to the sample.
