Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
132 words
A cover for tubing comprising: a tubular portion having first and second ends and having an inner surface which forms an opening of generally uniform diameter, said first end being configurated to receive the tubing within the opening, said tubular portion being formed from a flexible material; and a plurality of rib members formed on the inner surface of the tubular portion, said rib members being of increasing cross-sectional height from the first end to the second end of said tubular portion, such that said rib members form a diameter within the opening which is smaller than the outer diameter of the tubing, whereby the walls of said tubular portion between said plurality of rib members are deformed from cylindrical shape when the end of a length of tubing is inserted therein.
Claim 2
Dependent Claim
132 words
A cover for tubing comprising: a tubular portion having first and second ends and having an inner surface which forms an opening of generally uniform diameter, said first end being configurated to receive the tubing within the opening, said tubular portion being formed from a flexible material; and a plurality of rib members formed on the inner surface of the tubular portion, said rib members being of increasing cross-sectional height from the first end to the second end of said tubular portion, such that said rib members form a diameter within the opening which is smaller than the outer diameter of the tubing, whereby the walls of said tubular portion between said plurality of rib members are deformed from cylindrical shape when the end of a length of tubing is inserted therein.
Claim 3
Dependent Claim
30 words
A cover as defined in claim 1 further comprising gripping means for use in removing the cover, said gripping means being formed at the second end of the tubular portion.
Claim 4
Dependent Claim
22 words
A cover as defined in claim 1 wherein said rib members are evenly spaced about the inner surface of the tubular portion.
Claim 5
Dependent Claim
165 words
A cover for preserving the sterile condition of tubing to be used in medical procedures comprising: a tubular portion formed from a flexible material and having an inner diameter of generally uniform cross-section, which diameter is larger than an outer diameter of the tubing, said tubular portion having a first end forming an opening such that the tubing can be inserted therein; a second end of the tubular portion being closed so as to maintain the sterile condition of the tubing; at least three rib members integrally formed on an inner surface of the tubular portion, each of said rib members having an increased cross-sectional height from the first end to the second end of the tubular portion such that the diameter formed by the rib members decreased from the first end to the second end, whereby the walls of said tubular portion between said plurality of rib members are deformed from cylindrical shape when the end of a length of tubing is inserted therein.
Claim 6
Dependent Claim
165 words
A cover for preserving the sterile condition of tubing to be used in medical procedures comprising: a tubular portion formed from a flexible material and having an inner diameter of generally uniform cross-section, which diameter is larger than an outer diameter of the tubing, said tubular portion having a first end forming an opening such that the tubing can be inserted therein; a second end of the tubular portion being closed so as to maintain the sterile condition of the tubing; at least three rib members integrally formed on an inner surface of the tubular portion, each of said rib members having an increased cross-sectional height from the first end to the second end of the tubular portion such that the diameter formed by the rib members decreased from the first end to the second end, whereby the walls of said tubular portion between said plurality of rib members are deformed from cylindrical shape when the end of a length of tubing is inserted therein.
Claim 7
Dependent Claim
33 words
A cover as defined in claim 4 wherein said second end of the tubular portion is provided with a gripping means for removal of said cover from the tubing which is inserted therein.
Claim 8
Dependent Claim
21 words
A cover as defined in claim 4 comprising three rib members equidistantly spaced about the inner surface of the tubular portion.
Claim 9
Dependent Claim
40 words
A cover as defined in claim 4 wherein the diameter formed by the rib members decreases from the first end to the second end by an amount from about 15% to about 40% of the diameter of said tubular portion.
