Abstract
Abstract A urine drainage bag having an outlet tube provided with a hydrophilic coating on its inner wall surface and an antimicrobial substance such as iodine carried within a frangible capsule adapted to be received within the tube and said substance being absorbable by the coating when the capsule is ruptured. A method of treating a urine drainage bag outlet tube to prevent multiplication or growth of microorganisms utilizing a frangible carrier within the tube is taught.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
72 words
An outlet for a urine drainage bag, comprising an elongated outlet tube secured to the bottom portion of the drainage bag, at least a portion of the interior of said tube having a hydrophilic coating means thereon, a normally totally sealed frangible ampule containing an antimicrobial substance received in said outlet tube, the antimicrobial substance being absorbed by said coating means on the tube interior when the frangible ampule seal is broken.
Claim 2
Dependent Claim
72 words
An outlet for a urine drainage bag, comprising an elongated outlet tube secured to the bottom portion of the drainage bag, at least a portion of the interior of said tube having a hydrophilic coating means thereon, a normally totally sealed frangible ampule containing an antimicrobial substance received in said outlet tube, the antimicrobial substance being absorbed by said coating means on the tube interior when the frangible ampule seal is broken.
Claim 3
Dependent Claim
20 words
An outlet as defined in claim 1, wherein the frangible ampule has a fabric mesh or someother porous membrane covering.
Claim 4
Dependent Claim
15 words
The outlet as defined in claim 2 wherein the frangible ampule is made of glass.
Claim 5
Dependent Claim
13 words

Claim 8
Independent Claim
81 words
A method of treating the outlet tube of a urinary drainage bag to prevent passage, multiplication or growth of microorganisms comprising the steps of coating at least a portion of the interior of said tube with a hydrophilic material means, inserting a totally sealed frangible ampule carrier containing an antimicrobial substance into said tube where it may remain until ready for use, and breaking said carrier, whereby the antimicrobial substance may be absorbed by the hydrophilic coating means on said tube.
Claim 9
Independent Claim
81 words
A method of treating the outlet tube of a urinary drainage bag to prevent passage, multiplication or growth of microorganisms comprising the steps of coating at least a portion of the interior of said tube with a hydrophilic material means, inserting a totally sealed frangible ampule carrier containing an antimicrobial substance into said tube where it may remain until ready for use, and breaking said carrier, whereby the antimicrobial substance may be absorbed by the hydrophilic coating means on said tube.
