Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
139 words
A self-contained cleaning device for use in combination with endoscopic instruments having a tube portion for insertion into a body orifice, comprising: a generally cylindrical shaped sponge body having an axially aligned central bore sized to fit the tube portion of said instrument, said sponge body having a slit extending parallel to and in communication with said bore to permit said body to be fitted over said tube, said slit being narrow enough so that slight gripping pressure on said body is adequate to close said slit to cause sponge body contact with the complete circumference of said tube, said body further being sized to present a radial thickness outward from said bore at least equal to the diameter of said tube, and a brush extending outwardly from an end of said sponge body adapted to clean instrument portions.
Claim 2
Dependent Claim
139 words
