Abstract
Abstract An irrigation adapter which is connectable to a catheter and a drainage tube in a liquid drainage system. The adapter includes a flexible body member having a longitudinally extending main channel, a side arm having a channel extending through the side arm and communicating with the main channel through an opening intermediate the ends of the body member, and a pouch having an elongated cavity communicating with the main channel through an opening. The adapter also includes a control tube having an outside diameter of a size to sealingly engage the inside of the body member in the main channel of the distal portion of the body member, a first end fixed in the main channel adjacent a proximal end of the body member, and a second free end extending into the body member past the openings. The free end is movable between a first position in the main channel and a second position in the pouch by flexing or extending the body member. Thus, the free end sealingly engages the inside of the body member in the first position to prevent passage of liquid into the side arm and permit liquid drainage through the adapter, and the free end is receivable in the pouch cavity in the second position to close the drainage tube and permit irrigation of the catheter through the side arm.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
292 words
An adapter for a catheter and a drainage tube in a liquid drainage system, comprising: a flexible body member having a main channel extending longitudinally through the body member, a distal end for attachment to said catheter with said main channel communicating with a drainage lumen in the catheter, a proximal end for attachment to said drainage tube, an irrigation side arm having an irrigation channel extending through the side arm and communicating with the main channel through an opening intermediate the proximal and distal ends of said body member, and a pouch having an elongated cavity communicating with the main channel through an opening; and a control tube having an outside diameter of a size to sealingly engage the inside of the body member in the main channel of the distal portion of the body member, a first end fixed in the main channel adjacent the proximal body member end with a lumen in said control tube communicating with the drainage tube through said first end, and a second free end extending from the first end into the body member past the openings, said free end being movable between a first position in the main channel and a second position in the pouch cavity by flexing the body member, whereby the free end sealingly engages the inside of the body member in said first position to prevent passage of liquid into the irrigation channel and permit liquid drainage from the catheter to said drainage tube, and the free end is receivable in the pouch cavity in said second position to close the drainage tube and permit passage of liquid between the side arm channel and the distal end of the main channel for irrigation of the catheter through said irrigation channel.
Claim 2
Dependent Claim
292 words
An adapter for a catheter and a drainage tube in a liquid drainage system, comprising: a flexible body member having a main channel extending longitudinally through the body member, a distal end for attachment to said catheter with said main channel communicating with a drainage lumen in the catheter, a proximal end for attachment to said drainage tube, an irrigation side arm having an irrigation channel extending through the side arm and communicating with the main channel through an opening intermediate the proximal and distal ends of said body member, and a pouch having an elongated cavity communicating with the main channel through an opening; and a control tube having an outside diameter of a size to sealingly engage the inside of the body member in the main channel of the distal portion of the body member, a first end fixed in the main channel adjacent the proximal body member end with a lumen in said control tube communicating with the drainage tube through said first end, and a second free end extending from the first end into the body member past the openings, said free end being movable between a first position in the main channel and a second position in the pouch cavity by flexing the body member, whereby the free end sealingly engages the inside of the body member in said first position to prevent passage of liquid into the irrigation channel and permit liquid drainage from the catheter to said drainage tube, and the free end is receivable in the pouch cavity in said second position to close the drainage tube and permit passage of liquid between the side arm channel and the distal end of the main channel for irrigation of the catheter through said irrigation channel.
Claim 3
Dependent Claim
15 words
The adapter of claim 1 wherein said control tube is integral with the drainage tube.
Claim 4
Dependent Claim
240 words
An adapter for a liquid drainage system comprising: a flexible body member having a main channel extending longitudinally through the body member, a proximal end, a distal end, a side arm having a channel extending through the side arm and communicating with the main channel through an opening intermediate the ends of the body member, and a pouch having an elongated cavity communicating with the main channel through an opening, and a control tube having an outside diameter of a size to sealingly engage the inside of the body member in the main channel of the distal portion of the body member, a first end fixed in the main channel adajcent the proximal end of said body member, and a second free end extending from the first end into the body member past the openings, said free end being movable between a first position in the main channel and a second position in the pouch cavity by flexing the body member, whereby the free end sealingly engages the inside of the body member in said first position to prevent passage of liquid into the side arm channel and permit liquid drainage through the main channel and control tube, and the free end is receivable in the pouch cavity in said second position to close the control tube, open the side arm channel, and permit passage of liquid between the side arm channel and the distal end of the main channel.
Claim 5
Dependent Claim
