Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
97 words
A device for use in examining fecal matter for presence of ova comprising a vial open at one end, mixing means in the base of said vial remote from said open end, an elongated hollow strainer including a cup-like compartment at one terminal end adapted to contain a predetermined quantity of feces, the cup-like compartment engaging over said mixing means when the strainer is fully seated in the vial and adapted for limited oscillating movement relative to the vial to mix the feces and ensure good release of ova when a solution is added to the device.
Claim 2
Independent Claim
97 words
A device for use in examining fecal matter for presence of ova comprising a vial open at one end, mixing means in the base of said vial remote from said open end, an elongated hollow strainer including a cup-like compartment at one terminal end adapted to contain a predetermined quantity of feces, the cup-like compartment engaging over said mixing means when the strainer is fully seated in the vial and adapted for limited oscillating movement relative to the vial to mix the feces and ensure good release of ova when a solution is added to the device.
Claim 3
Dependent Claim
69 words
A device as claimed in claim 1 wherein said mixing means comprises a blade projecting upwardly from the base of the vial of a maximum cross sectional dimension smaller than the diameter of the cup-like compartment at said one terminal end of the vial, and wherein said compartment is formed with at least one fin section, cooperatively associated with said blade to produce good mixing of a fecal specimen.
Claim 4
Dependent Claim
69 words
A device as claimed in claim 2 including a pair of ribs on the interior wall of the vial and wherein said strainer includes a pair of lugs, the lugs and ribs being selectively oriented relative to the mixing blade so that upon rotation of the vial the strainer lugs engage the ribs to limit rotation of the strainer and prevent engagement of the fin section and mixing blade.
Claim 5
Dependent Claim
61 words
A device as claimed in claim 2 wherein said mixing blade includes a post section with a tip projecting beyond the upper edge of the blade engageable with a wall spaced from the lower terminal edge of the strainer defining the base of the cup-like compartment providing a two point pivot facilitating easy rotation of the strainer relative to the vial.
Claim 6
Dependent Claim
37 words
A device as claimed in claim 1 wherein said strainer comprises enlarged head section connected to the tip of the vial by a radial wall and including means defining a plurality of openings in the radial wall.
Claim 7
Dependent Claim
45 words
A device as claimed in claim 5 wherein said openings are defined by a gridwork whose edges are sharply angled faces which converge to a sharp edge thereby to provide for more fluid flow of ova without obstruction to the head section of the strainer.
Claim 8
Dependent Claim
64 words
A device as claimed in claim 5 wherein the vial has an enlarged pilot section and includes a circumferentially extending radially inwardly directed rib, said head section of the strainer engaging said rib to provide a seal and the interior wall of the vial aligning with the interior wall of the head section of strainer when the strainer is fully seated in the vial.
