Tube fixation device
First Claim
1. A tube fixation device for the angular fixation of tubes used for the delivery, extraction, or evacuation of fluids or gases through a surgically formed stoma, the tube being generally circular and deformable and having an inlet end and an outlet end, said tube extending outwardly from the patient to carry components of said device, the components of said tube fixation device comprising:
- (a) a sleeve disposed along and movable along said tube towards a base elbow unit, said sleeve having a relatively narrow tube-engaging end frictionally engaging said tube, and said sleeve also having an opposite, interlocking end;
(b) a base elbow unit through which said tube passes, said base elbow unit including a subdermal portion and a sleeve engaging portion having a common first axis with said subdermal portion, said base elbow unit further including a generally cylindrical tube-engaging portion and oriented along a second axis, said second axis being selectively angled at an acute angle relative to said first axis, the inner diameter of said tube-engaging portion being slightly less than the outer diameter of said tube, andwherein said tube is movable from a first, substantially straight position in which said tube passes through and is slidably movable within said subdermal portion and said sleeve engaging portion of said elbow; and
a second, selectively angled position in which said tube also passes through said tube engaging portion, and wherein said tube is immobilized by locking engagement to said tube engaging portion, and said tube fixation device further comprising(c) an interlocking tab at said interlocking end of said sleeve, said sleeve and said interlocking tab being movable along said tube to a position wherein said tab lockingly engages said sleeve engaging portion of said base elbow unit when said tube is in said second, selectively angled position.

Abstract
The invention is a device for angular fixation of a delivery or drainage tube at, for example, the point where that tube exits through the skin from a body cavity. The tube may be used for delivery, extraction, or evacuation of fluids or gases through a surgically formed stoma in a patient. In the enteral feeding, or delivery, embodiment, an enteral feeding tube extends outwardly from the patient to support the components of the device. The components include a sleeve disposed along and movable along the feeding tube and a base elbow unit through which the feeding tube passes. The base elbow unit includes a subdermal portion, a sleeve engaging portion, and a generally cylindrical tube-engaging portion. The feeding tube is movable from a first, substantially straight position to a second, acutely angled position. In this second, acutely angled position, the tube is immobilized by locking engagement to the tube engaging portion. The device includes an interlocking tab at one end of the sleeve, which tab enables locking engagement of the sleeve engaging portion of the base elbow unit when the tube is in its second, acutely angled position.

3. A tube fixation device for the angular fixation of a tube used in the delivery, extraction, or evacuation of fluids through a surgically formed stoma in a patient, comprising:
-
(a) a generally circular, deformable, elongated tube having an inlet end and an outlet end, said tube extending outwardly from the patient to support additional components of said device; (b) a sleeve disposed along and movable along said tube and proximate said inlet end, said sleeve having a relatively narrow tube-engaging end frictionally engaging said tube, and said sleeve also having an opposite, interlocking end; (c) a base elbow unit through which said tube passes towards a base elbow unit, said base elbow unit including a subdermal portion and a sleeve engaging portion having a common first axis with said subdermal portion, said base elbow unit further including a generally cylindrical tube-engaging portion and oriented along a second axis, said second axis being at an acute angle to said first axis, the inner diameter of said tube-engaging portion being slightly less than the outer diameter of said tube, and wherein said tube is movable from a first, substantially straight position in which said tube passes through and is slidably movable within said subdermal portion and said sleeve engaging portion of said elbow, and a second, acutely angled position in which said tube also passes through said tube engaging portion, and wherein said tube is immobilized by locking engagement to said tube engaging portion, and further comprising (d) an interlocking tab at said interlocking end of said sleeve, said sleeve and said interlocking tab being movable along said tube to a position wherein said tab lockingly engages said sleeve engaging portion of said base elbow unit when said tube is in said second, acutely angled position. - View Dependent Claims (4)
