Abstract
Abstract This invention relates to medical apparatus for such usages as urological irrigation, and in one embodiment comprises twin bags of solution, each of which has a valved orifice that may be removably connected in the mid-section of an irrigation tube, which may be folded over into contacting juxtaposition with each other and manually squeezed simultaneously so as to force solution through both the upper and the lower segments of the tube at the same time.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
200 words
A method of admitting solution from a first source into one of a pair of tubes which is connectable into tandem relationship with the other of said pair of tubes, concurrently with admitting solution from a second source into the other of said tubes comprising the steps of disconnecting said tubes from each other, connecting one of said tubes to one of the egress means of apparatus comprising a pair of manually collapsible solution containers which are structurally integral with each other without a solution flowpath therebetween, each of which has a solution egress means, the egress means in each of said containers being positioned at the end thereof opposite the end of the other of said containers at which the egress means therein is positioned, wherein said containers are pouch-like and are structurally integrated with each other by means of a hinge-like juncture about which said containers may be swung into contact side-by-side with each other, connecting the other of said tubes to the other of said egress means, folding said containers over into side-by-side relationship, concurrently manually squeezing both of said containers, disconnecting both of said tubes from said egress means, and reconnecting said tubes to each other.
Claim 2
Independent Claim
200 words
A method of admitting solution from a first source into one of a pair of tubes which is connectable into tandem relationship with the other of said pair of tubes, concurrently with admitting solution from a second source into the other of said tubes comprising the steps of disconnecting said tubes from each other, connecting one of said tubes to one of the egress means of apparatus comprising a pair of manually collapsible solution containers which are structurally integral with each other without a solution flowpath therebetween, each of which has a solution egress means, the egress means in each of said containers being positioned at the end thereof opposite the end of the other of said containers at which the egress means therein is positioned, wherein said containers are pouch-like and are structurally integrated with each other by means of a hinge-like juncture about which said containers may be swung into contact side-by-side with each other, connecting the other of said tubes to the other of said egress means, folding said containers over into side-by-side relationship, concurrently manually squeezing both of said containers, disconnecting both of said tubes from said egress means, and reconnecting said tubes to each other.
Claim 3
Dependent Claim
32 words
The method described in claim 1 including the step of rendering said egress means into condition for passing solution therethrough by manipulating valve means integral therewith prior to said manual squeezing step.
