Abstract
Abstract A method for sampling feces, by which an approximately constant amount of feces can be sampled in simple manner and it is possible to easily identify whether occult blood is present in the feces or not. The method comprises a main container for a liquid for suspending feces in it, a cap arranged a one end of said main container, a separating means for dividing inner spaces of the main container and the cap, a through-hole formed in the separating means, and a collecting stick having a means for collecting feces engaged and inserted in the through-hole, wherein the means for collecting feces is composed of a plurality of hairs and arranged at or near the forward end of the collecting stick, whereby feces collected by the means for collecting feces being composed of said plurality of hairs are passed into the through-hole of the separating means in order to sample an approximately constant amount of the feces.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
190 words
A method for collecting a feces sample and for preparing a suspension of feces in a liquid, comprising: providing a sampling device comprising a feces collector including a feces collecting rod having a plurality of hairs formed on or near a tip of the collecting rod and extending radially outwardly from the collecting rod, and a container defining an internal space accommodating the liquid, the container having separating means formed with a through-hole having a dimension smaller than the radial outward extension of the hairs, rolling said hairs of said feces collecting rod over a surface of the feces to collect a feces on said hairs, inserting said feces collecting rod with said feces collected thereon through the through-hole of the separating means of the container to thereby lay down said plurality of hairs and push excessive feces upwardly, a feces sample being retained on said feces collecting rod almost quantitatively, and to erect said plurality of hairs vertically after passage through said through-hole, and, suspending said feces sample retained on said collecting rod after passage through the through-hole in the liquid contained in the internal space of the container.
Claim 2
Independent Claim
190 words
A method for collecting a feces sample and for preparing a suspension of feces in a liquid, comprising: providing a sampling device comprising a feces collector including a feces collecting rod having a plurality of hairs formed on or near a tip of the collecting rod and extending radially outwardly from the collecting rod, and a container defining an internal space accommodating the liquid, the container having separating means formed with a through-hole having a dimension smaller than the radial outward extension of the hairs, rolling said hairs of said feces collecting rod over a surface of the feces to collect a feces on said hairs, inserting said feces collecting rod with said feces collected thereon through the through-hole of the separating means of the container to thereby lay down said plurality of hairs and push excessive feces upwardly, a feces sample being retained on said feces collecting rod almost quantitatively, and to erect said plurality of hairs vertically after passage through said through-hole, and, suspending said feces sample retained on said collecting rod after passage through the through-hole in the liquid contained in the internal space of the container.
