Abstract
Abstract A combination catheter and drainage system includes a flexible tubular member oligodynamically treated in part and having an aperture adjacent said one end to allow communication between a main lumen and the exterior of the tubular member, a balloon being provided adjacent the aperture and an auxiliary lumen being connected to the main lumen for inflating the balloon and a urine collecting bag connected to the tubular member via a connector means which is oligodynamically treated. The collecting bag is also provided at its discharge distal end with an oligodynamically active metal device thereby forming a system which is completely closed against entry of ambient microorganisms.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
174 words
A catheter and drainage system adapted to be carried by a person and utilized to drain urine from a to-be-drained body cavity of said person to a drainage bag carried by said person comprising, in combination, an indwelling catheter adapted to extend partially into said body cavity, said catheter comprising a flexible tubular member having a main lumen for urine discharge, one end of said main lumen being closed, said tubular member having an aperture adjacent to said one end to allow communication between said main lumen and the exterior of said tubular member, a balloon provided adjacent said aperture, an auxiliary lumen connected to said main lumen for inflating said balloon, an oligodynamically active metal deposited on a portion of only the outside periphery of said tubular member for producing metal ions upon contact with the urine, a urine collecting bag adapted to be carried by said person, said collecting bag having an inlet, and a tubular sterilizing means having oligodynamic activity connecting said catheter tube to said inlet of said collecting bag.
Claim 2
Dependent Claim
174 words
A catheter and drainage system adapted to be carried by a person and utilized to drain urine from a to-be-drained body cavity of said person to a drainage bag carried by said person comprising, in combination, an indwelling catheter adapted to extend partially into said body cavity, said catheter comprising a flexible tubular member having a main lumen for urine discharge, one end of said main lumen being closed, said tubular member having an aperture adjacent to said one end to allow communication between said main lumen and the exterior of said tubular member, a balloon provided adjacent said aperture, an auxiliary lumen connected to said main lumen for inflating said balloon, an oligodynamically active metal deposited on a portion of only the outside periphery of said tubular member for producing metal ions upon contact with the urine, a urine collecting bag adapted to be carried by said person, said collecting bag having an inlet, and a tubular sterilizing means having oligodynamic activity connecting said catheter tube to said inlet of said collecting bag.
Claim 3
Dependent Claim
121 words
A draining system adapted to be carried by a person and utilized to conduct body fluids from an insertable device extending partially into a to-be-drained body cavity of said person to a drainage bag carried by said person, the combination corprising a catheter tube adapted to extend partially into said body cavity, said catheter tube being coated with an oligodynamically active metal only on the outside periphery for producing metal ions upon contact with said body fluids, a drainage bag adapted to be carried by said person, and a connector means connecting said catheter tube to said drainage bag, said connector neans having an oligodynamically active metal to provide a barrier against intrusion of ambient infecting organisms into said catheter tube.
Claim 4
Dependent Claim
121 words
A draining system adapted to be carried by a person and utilized to conduct body fluids from an insertable device extending partially into a to-be-drained body cavity of said person to a drainage bag carried by said person, the combination corprising a catheter tube adapted to extend partially into said body cavity, said catheter tube being coated with an oligodynamically active metal only on the outside periphery for producing metal ions upon contact with said body fluids, a drainage bag adapted to be carried by said person, and a connector means connecting said catheter tube to said drainage bag, said connector neans having an oligodynamically active metal to provide a barrier against intrusion of ambient infecting organisms into said catheter tube.
Claim 5
Dependent Claim
46 words
A draining system according to claim 2, wherein said connector means comprises a tubular member having an oligodynamically active metal deposited on the outside surface thereof to provide a barrier against intrusion of ambient infecting organisms into said catheter tube and up toward the body cavity.
Claim 6
Dependent Claim
17 words
A draining system according to claim 2, wherein said connector means comprises a pipe made of copper.
Claim 7
Dependent Claim
28 words
A draining system according to claim 2, wherein said oligodynamically active metal is selected from the group consisting of silver, gold, copper, their alloys, and intermetallic compounds thereof.
Claim 8
Dependent Claim
123 words
A draining system adapted to be carried by a person and utilized to conduct body fluids from an insertable device extending partially into a to-be-drained body cavity of said person to a drainage bag carried by said person, the combination comprising a catheter tube adapted to extend partially into said body cavity, said catheter tube being coated with a oligodynamically active metal only on the outside periphery for producing metal ions upon contact with said body fluids, a drainage bag adapted to be carried by said person, said drainage bag having an inlet, and an oligodynamically active tubular member connecting said catheter tube to said inlet of said drainage bag, said oligodynamically active tubular member precluding bacteria from ascending from said drainage bag.
Claim 9
Dependent Claim
123 words
A draining system adapted to be carried by a person and utilized to conduct body fluids from an insertable device extending partially into a to-be-drained body cavity of said person to a drainage bag carried by said person, the combination comprising a catheter tube adapted to extend partially into said body cavity, said catheter tube being coated with a oligodynamically active metal only on the outside periphery for producing metal ions upon contact with said body fluids, a drainage bag adapted to be carried by said person, said drainage bag having an inlet, and an oligodynamically active tubular member connecting said catheter tube to said inlet of said drainage bag, said oligodynamically active tubular member precluding bacteria from ascending from said drainage bag.
Claim 10
Dependent Claim
153 words
A draining system adapted to be carried by a person and utilized to conduct body fluids from an insertable device extending partially into a to-be-drained body cavity of said person to a drainage bag carried by said person, the combination comprising a catheter tube adapted to extend partially into said body cavity, said catheter tube being coated with an oligodynamically active metal only on the outside periphery for producing metal ions upon contact with said body fluids, a drainage bag having an inlet and an outlet, a first oligodynamically active tubular member connecting said catheter tube to said inlet of said drainage bag, said first oligodynamically active tubular member precluding bacteria from ascending from said drainage bag, a second oligodynamically active tubular member connected to said outlet of said drainage bag and oligodynamically preventing entry of bacteria from the ambient atmosphere, and a removable closure member on said second oligodynamically active tubular member.
