Abstract
A fecal parasite concentrator which has a cylindrical body (20) with connections for a sample vial (24) on one end and a centrifuge tube (28) on the other. An integral filter (36) is disposed within the body at right angles coaxially covering the cross sectional area of the hollow body. The filter contains a series of closely spaced square openings for filtration of a liquid diluted fecal specimen. A hollow stem (40) with truncated end (44) extends upwardly from the filter and a number of geometrically shaped orifices (46) permit air to pass therethrough when the diluant specimen flows through the filter.
Claims13
A fecal parasite concentrator filter comprising:
- (a) a cylindrical body having a first end and a second end,
- (b) sample vial connection means integrally molded with the body first end for fastening a sample vial containing a liquid diluent fecal specimen,
- (c) centrifuge tube connection means integrally molded with the body second end for attaching a centrifuge tube thereupon,
- (d) a filter integrally molded with the body and extending into the centrifuge tube connecting means and terminating across the body at right angles for straining and retaining excess fecal debris from a liquid diluent specimen,
- (e) a hollow stem integrally molded with said filter, the hollow stem centrally upstanding and parallel with the body first end, the hollow stem abutting the filter at a filter abutment end being coterminous therewith, an upstanding end of the hollow stem at an opposite end to the filter abutment end, for equalizing pressure between the sample vial and the centrifuge tube connected to the body ends when liquid diluted fecal specimen flows therebetween, and
- (f) a truncated end inherent with the hollow stem having a plurality of orifices permitting air to pass therethrough while restricting solid matter.
