Abstract
Abstract An Urethral Catheter Holder is a device that has two semicylindric elements hinged with each other by a flexible living hinge on one edge. It has a single non adjustable male and female locking tooth on the other edges opposite to the living hinge. It has a semicylindric rim extension at one end of the device that extends to a diameter larger than said semicylindrical segment. There is a wedge defect at the living hinge side of the rim extension. The defect of the rim extension is covered by the curve extension cover. There is a compressible foam pad lining the surface of the semicylindric element and rim extension. The foam pad on the rim extension is impregnated with antimicrobial agent. When the device is placed in operative position, it forms a lumen inner to the foam pads able to hold and affix the Foley catheter without compromising and distorting the lumen of the catheter and the balloon inflation and deflation tube. It also provides a semi closed housing space for the male external urethral meatus and allows contact between the antimicrobial ointment and said urethral meatus. It reduces the incidence of ascending cather associated urinary tract infection.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
226 words
A urethral Foley catheter holder for gripping an indwelling urethral Foley catheter and impregnating an antimicrobial agent at the urethral meatus comprising: a) a first short semicylindrical segment with a semicylindrical rim extension at one end that extends to a diameter larger than said short semicylindrical segment, said short segment comprising a foam pad lining the inner surface thereof and said rim extension comprising a foam pad impregnated with an antimicrobial agent lining the inner surface thereof; b) a second short semicylindrical segment with a semicylindrical rim extension at one end that extends to a diameter larger than said short semicylindrical segment, said short segment comprising a foam pad lining the inner surface thereof and said rim extension comprising a foam pad impregnated with an antimicrobial agent lining the inner surface thereof; c) a living hinge or web at one edge of each short semicylindrical segment to allow connection of said short semicylindrical segments together to form a tubular structure with a central lumen inner of the foam pads to accommodate the Foley catheter; and d) a locking mechanism comprising a male locking tooth on said first short semicylindrical segment on the edge opposite said hinge or web and a female locking notch on said second short semicylindrical segment on the edge opposite said hinge or web to facilitate locking the device in an operative position.
Claim 2
Dependent Claim
226 words
A urethral Foley catheter holder for gripping an indwelling urethral Foley catheter and impregnating an antimicrobial agent at the urethral meatus comprising: a) a first short semicylindrical segment with a semicylindrical rim extension at one end that extends to a diameter larger than said short semicylindrical segment, said short segment comprising a foam pad lining the inner surface thereof and said rim extension comprising a foam pad impregnated with an antimicrobial agent lining the inner surface thereof; b) a second short semicylindrical segment with a semicylindrical rim extension at one end that extends to a diameter larger than said short semicylindrical segment, said short segment comprising a foam pad lining the inner surface thereof and said rim extension comprising a foam pad impregnated with an antimicrobial agent lining the inner surface thereof; c) a living hinge or web at one edge of each short semicylindrical segment to allow connection of said short semicylindrical segments together to form a tubular structure with a central lumen inner of the foam pads to accommodate the Foley catheter; and d) a locking mechanism comprising a male locking tooth on said first short semicylindrical segment on the edge opposite said hinge or web and a female locking notch on said second short semicylindrical segment on the edge opposite said hinge or web to facilitate locking the device in an operative position.
Claim 3
Dependent Claim
42 words
The urethral catheter holder according to claim 1 further comprising a wedge defect on each said semicylindrical rim extension at the hinged or webbed edge, to facilitate the opening of the device and accommodation of the Foley catheter in the central lumen.
Claim 4
Dependent Claim
18 words
The urethral catheter holder according to claim 2, wherein one wedge defect has a curve extension cover thereon.
