Abstract
Abstract A reuseable catheterization unit, including a catheter member of a predetermined diameter, a hollow flexible sleeve means connected at one end to the large diameter portion of the catheter and a hollow tubular connector means positioned at the opposite end of the sleeve means and axially spaced from the anterior end of the catheter, said connector mean adapted to sealingly connect with the large tubular end of the catheter to form a closed ring capable of sealingly retaining an antiseptic fluid within the lumen of the sleeve as well as contacting the exterior and lumen of the catheter for aseptic storage between catheterization procedures.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
214 words
A reuseable catheter unit including a catheter member of a predetermined diameter through a substantial part of its extent and having a closed anterior end, at least one side port adjacent said anterior end which communicates with a lumen passing through the remainder of said catheter member, an enlarged distal end having a large diameter portion connected by a tapered wall portion to the predetermined catheter member diameter, aperture means on said tapered wall portion communicating between the interior and exterior of said tapered wall portion, flexible sleeve means connected at one end to said large diameter portion and encasing said catheter member throughout all of its length and hollow tubular connector means positioned at the opposite end of said sleeve means, said tubular connector means axially spaced from the anterior end of said catheter member and further including a bore greater than said predetermined diameter, said connector means and said enlarged distal end of the catheter member having cooperative means for sealingly connecting to one another when said sleeve and the catheter member contained therein are formed into a circle thereby forming a closed ring capable of sealingly retaining an antiseptic fluid within the lumen of the sleeve and the exterior and lumen of said catheter member for aseptic storage between catheterization procedures.
Claim 2
Dependent Claim
214 words
A reuseable catheter unit including a catheter member of a predetermined diameter through a substantial part of its extent and having a closed anterior end, at least one side port adjacent said anterior end which communicates with a lumen passing through the remainder of said catheter member, an enlarged distal end having a large diameter portion connected by a tapered wall portion to the predetermined catheter member diameter, aperture means on said tapered wall portion communicating between the interior and exterior of said tapered wall portion, flexible sleeve means connected at one end to said large diameter portion and encasing said catheter member throughout all of its length and hollow tubular connector means positioned at the opposite end of said sleeve means, said tubular connector means axially spaced from the anterior end of said catheter member and further including a bore greater than said predetermined diameter, said connector means and said enlarged distal end of the catheter member having cooperative means for sealingly connecting to one another when said sleeve and the catheter member contained therein are formed into a circle thereby forming a closed ring capable of sealingly retaining an antiseptic fluid within the lumen of the sleeve and the exterior and lumen of said catheter member for aseptic storage between catheterization procedures.
Claim 3
Dependent Claim
49 words
A unit of the type claimed in claim 1 wherein said tubular connector means is tapered at its free end opposite the end connected to said sleeve means and said free end is acceptable within said large diameter portion at the distal end of the catheter in sealing engagement.
Claim 4
Dependent Claim
31 words
A unit of the type claimed in claim 1 wherein the tubular connector means encircles and overlies the large diameter of the distal end of the catheter member in sealing arrangement.
Claim 5
Dependent Claim
38 words
A unit of the type claimed in claim 1 wherein said sleeve means is a thin wall rubber tube capable of being axially corrugated to feed the catheter member out through the bore of the tubular connector means.
Claim 6
Dependent Claim
35 words
A unit of the type claimed in claim 1 wherein said sleeve is a flexible plastic sheath capable of being corrugated during the axial movement of the tubular connector means relative to the catheter member.
Claim 7
Dependent Claim
36 words
A unit of the type claimed in claim 4 wherein said rubber tube is adhesively connected to the tubular connector means at one end and adhesively connected to the enlarged distal end of the catheter member.
Claim 8
Dependent Claim
71 words
A unit of the type claimed in claim 1 wherein said apertured means on said tapered wall portion communicates between the lumen of the catheter member and the lumen of the sleeve means whereby air within the sleeve means can be evacuated out the enlarged distal end of the catheter member as said sleeve means is axially moved and corrugated during feeding of the catheter member through the tubular connector means.
Claim 9
Dependent Claim
35 words
A unit of the type claimed in claim 1 wherein said enlarged distal end of the catheter member is capable of being connected to a vented container for receiving a urine sample during catheterization procedures.
