Abstract

Abstract A urethral catheter tube formed of a flexible low-friction plastic is carried in a transparent plastic casing one end of which is flattened and severably joined to a plastic cap member. The other end of the casing is closed to form a reservoir. The cap member is a closed vessel containing a lubricant. When the cap is separated from the casing it can be opened to permit application of the lubricant and the casing also opened to permit insertion and implantation of the catheter. Both the lubricant and the catheter tube can be maintained in a sterilized condition and the catheter remains sterile during implantation since it can be worked out of the casing by aseptically contacting it through the casing walls, the net result being that the catheter need not be contacted by human hands.

Claims Analysis

Total Claims: 11
Claim 1
Independent Claim 182 words
Disposable catheter apparatus comprising: a flexible transparent elongate open-ended tubular casing member having one of its ends closed for providing a baglike receptible portion, an elongate flexible catheter tube longitudinally disposed within said casing, a cuplike open-ended capping member having its open end portion sized to match the open end portion of said casing member, fluid catheterization material carried by said capping member, the open ends of the casing and capping members being pressed together to provide a flattened sheetlike multi-ply section common to both members anD said section having its plies severably united for sealably closing both of said members, whereby the contents of said members can be maintained in a sterilized condition and the catheterization can be conducted by separating said members and reopening said open ends, the reopening permitting said sterilized fluid material to be applied for catheterization and said sterile catheter tube to be worked out of said casing for implantation by asceptically manipulating the catheter tube through contact with the casing, said envelope then providing a baglike reservoir for receiving fluids delivered through the implanted catheter tube.
Claim 2
Dependent Claim 182 words
Disposable catheter apparatus comprising: a flexible transparent elongate open-ended tubular casing member having one of its ends closed for providing a baglike receptible portion, an elongate flexible catheter tube longitudinally disposed within said casing, a cuplike open-ended capping member having its open end portion sized to match the open end portion of said casing member, fluid catheterization material carried by said capping member, the open ends of the casing and capping members being pressed together to provide a flattened sheetlike multi-ply section common to both members anD said section having its plies severably united for sealably closing both of said members, whereby the contents of said members can be maintained in a sterilized condition and the catheterization can be conducted by separating said members and reopening said open ends, the reopening permitting said sterilized fluid material to be applied for catheterization and said sterile catheter tube to be worked out of said casing for implantation by asceptically manipulating the catheter tube through contact with the casing, said envelope then providing a baglike reservoir for receiving fluids delivered through the implanted catheter tube.
Claim 3
Dependent Claim 31 words
The apparatus of claim 1 further including means for positively retaining a portion of the tube within the casing whereby the retained portion provides a conduit communicating with said baglike receptacle.
Claim 4
Dependent Claim 48 words
The apparatus of claim 2 wherein said retaining means includes a ferrule fixedly disposed interiorally of said casing and a flanged lock ring carried by said catheter tube, said lock ring mating with said ferrule whereby said flanged portion restrains movement of the tube outwardly of the casing.
Claim 5
Dependent Claim 16 words
The apparatus of claim 2 wherein said catheter tube is formed of a smooth low-friction plastic.
Claim 6
Dependent Claim 26 words
The apparatus of claim 4 wherein said fluid material is a lubricant adapted to be applied to the catheter tube and the patient for facilitating catheterization.
Claim 7
Dependent Claim 19 words
The apparatus of claim 2 wherein said baglike receptacle portion of the casing is expandable to increase its capacity.
Claim 8
Dependent Claim 17 words
The apparatus of claim 6 wherein said baglike receptacle is formed with longitudinal pleats permitting said expansion.
Claim 9
Dependent Claim 17 words
The apparatus of claim 7 wherein said pleated portion bears indices designating volumetric contents of the reservoir.
Claim 10
Dependent Claim 29 words
The apparatus of claim 1 wherein said casing and capping members both are formed of a heat-sealable plastic material and said sheetlike section common to both members is heat-sealed.
Claim 11
Dependent Claim 22 words
The apparatus of claim 1 wherein said common section includes a weakened portion extending as a tear line transversely of the section.
