Excrement examination unit

Claim 1

An excrement examination unit comprising: a handle means including a tubular handle portion having a cavity formed in said tubular handle portion, an uppermost removable cover formed on a top end of the tubular handle portion and operatively sealing the handle cavity and having a needle hole formed through said cover, a contrast test paper adhered on an inner surface of said cover sealable on said needle hole of said cover, a hollow stem connected to and positioned under said tubular handle portion having at least a venting hole formed in said stem, a stirring rake member connected on a lowest end of said stem, and a membrane adhered on a top end of said stem in said cavity, whereby upon a perforation by an external needle in said contrast test paper and said membrane through said needle hole of said cover, an air passage is formed through said hole of said cover, said perforated contrast test paper, said perforated membrane, and said venting hole of said hollow stem; a housing for encasing and holding said handle means including an upper hollow portion, a lower base portion formed under said upper hollow portion, a first partition plate formed between said upper hollow portion and said lower base portion, a second partition plate formed in a middle position in said upper hollow portion above said first partition plate, said second partition plate including a drain hole, said lower base portion having a bottom tube protruding downwardly from said first partition plate, a rectangular slot formed in a side wall of said upper hollow portion between said second partition plate and said first partition plate, a housing cap sealingly secured to a top portion of said upper hollow portion and packed by a packing member, said packing member having a stem hole formed therein for inserting said hollow stem for holding said handle means in said housing; a valve means having a water-proof sheet member normally sealing said drain hole of said second partition plate and a tab portion protruding outwardly from said sheet member through a slit laterally formed in said upper hollow portion adjacent to said second partition plate; a filter means held on a supporting ring retained between said upper hollow portion and said lower base portion above said first partition plate, said filter means being liquid penetrable; and an actual test paper adhered on said filter means by poking through said rectangular slot, an upper chamber being defined between said second partition plate and said housing cap and a lower chamber defined between said second partition plate and said first partition plate, whereby upon an opening of the valve means to discharge a fecal solution which is made in said upper chamber by mixing a fecal sample kept on said rake member and a medical saline solution injected through said packing member into said lower chamber, the fecal solution as partially absorbed on said filter means will penetrate into said actual test paper for a preliminary test for a detection of a hemorrhage and a fecal solution is drained into a test tube connected under said bottom tube for further laboratory test of a microscopic inspection of parasites existing in the fecal sample.
