Patent ID: 7896848

Claim:
An ostomy tube device, comprising: (a) a hollow flexible tube having a first end, a second end and a lumen opened at both said first end and said second end; (b) a collapsible internal retention member surrounding the first end of said hollow flexible tube and being secured thereto; (c) a tapered cannula having a wide portion ending by a wide end and a tapered portion ending by a tapered end, and a lumen open on both said tapered end and said wide end; said lumen of said wide portion of said tapered cannula is sized to accommodate folded and collapsed said second end of said hollow flexible tube; (d) a pull-loop member constructed from a flexible thread having a leading pole loop at one pole and a rear pole loop at another pole; said pull-loop member being passed through the lumen of said tapered cannula so that said leading pole loop extends from said tapered end of said tapered cannula, and said rear pole loop extends out of said wide portion of said tapered cannula through said wide end, wherein said second end of said hollow flexible tube is positioned through said rear pole loop extending out of said wide portion of said tapered cannula through said wide end; pulling said tapered cannula and said leading pole loop apart pulls said rear pole loop into the lumen of said wide portion of said tapered cannula; said second end of said hollow flexible tube folds over said rear pole loop and squeezes into the lumen of said wide portion of said tapered cannula pulled by said rear pole loop to provide a secure and releasable attachment between said pull-loop member, said tapered cannula and said hollow flexible tube; said attachment is strong enough to overcome resistance forces on said ostomy tube device while it is pulled by said leading pole loop through a lumen and a wall of hollow organ and abdominal wall; said second end of said hollow flexible tube is easy to disengage from said attachment by simply pulling apart said hollow flexible tube and said tapered cannula, eliminating the need of sharp devices as scissors, knifes, cutting pliers to cut said hollow flexible tube or said pull-loop member to release said hollow flexible tube from the attachment with said tapered cannula and said pull-loop.
