Abstract

Abstract A feline stomach tube speculum in the form of a double-tapered wedge bar having an elongated central portion dimensioned to fit in and extend transversely across a cat''s mouth, and two tip portions extending axially outwardly from the central portion and each tapering down to a narrow terminal edge. The central portion has one hole extending transversely through it for receiving a stomach tube and a pair of holes respectively on opposite sides of the tube hole and in substantially perpendicular relation to the tube hole for receiving the fangs of a cat. The tube hole is preferably parallel to the tip edges. The wedge bar also serves as a jaw opener.

Claims Analysis

Total Claims: 7
Claim 1
Independent Claim 164 words
A stomach tube speculum, comprising a double-tapered wedge bar having an elongated central portion dimensioned to fit in and extend transversely across the mouth of an animal which has fangs projecting farther than teeth between the fangs, said wedge bar further having two tip portions projecting axially outwardly in opposite directions from said central portion, each of said tip portions tapering down progressively from said central portion to a narrow edge for insertion in the mouth of the animal progressively until said central portion is located in the mouth of the animal thereby spreading the jaws, said central portion having a first hole extending through the same for receiving a stomach tube and having second and third holes therein on opposite sides of said first hole for receiving the fangs of the animal, said first hole being substantially parallel to said edges and said second and third holes being substantially perpendicular to said first hole and extending at least about halfway through said bar.
Claim 2
Dependent Claim 164 words
A stomach tube speculum, comprising a double-tapered wedge bar having an elongated central portion dimensioned to fit in and extend transversely across the mouth of an animal which has fangs projecting farther than teeth between the fangs, said wedge bar further having two tip portions projecting axially outwardly in opposite directions from said central portion, each of said tip portions tapering down progressively from said central portion to a narrow edge for insertion in the mouth of the animal progressively until said central portion is located in the mouth of the animal thereby spreading the jaws, said central portion having a first hole extending through the same for receiving a stomach tube and having second and third holes therein on opposite sides of said first hole for receiving the fangs of the animal, said first hole being substantially parallel to said edges and said second and third holes being substantially perpendicular to said first hole and extending at least about halfway through said bar.
Claim 3
Dependent Claim 19 words
The speculum as claimed in claim 1 in which said second and third holes extend completely through said bar.
Claim 4
Dependent Claim 22 words
The speculum as claimed in claim 2 in which said central portion of said wedge bar is substantially squared in cross section.
Claim 5
Dependent Claim 17 words
The speculum as claimed in claim 1 in which said wedge bar is made of plastic material.
Claim 6
Dependent Claim 147 words
A feline stomach tube speculum, comprising a wedge bar having an elongated central portion dimensioned to fit in a cat''s mouth and extend transversely thereof, said wedge bar further having two tip portions projecting longitudinally outwardly in opposite directions from said central portion and each tapering down from said central portion To a narrow edge for insertion in the mouth of a cat whereby further insertion of said bar places said central portion in the cat''s mouth to spread the jaws of the cat, said central portion having a tube hole extending through the same for receiving a stomach tube, and said central portion further having a pair of apertures on opposite sides of said tube hole for receiving a cat''s fangs, said tube hole being generally parallel to said edges and said apertures being generally perpendicular to said tube hole and extending completely through said bar.
