Abstract: A collapsible dispensing tube such as a toothpaste tube or the like includes structure for maintaining the dispensing tube in a coiled position as the viscous material within the dispensing tube is expelled. The tube is provided with a slot formed in a first side of its exterior surface and a plurality of engaging elements positioned on a second side of the exterior surface. The slot and engaging elements are correspondingly sized such that the slot receives the engaging elements securely when the engaging element side of the tube is coiled onto the slot side of the tube. This construction readily prevents a dispensing tube from uncoiling to thereby more efficiently dispense the material within the tube.

Abstract: A knitted tubular fabric is made from a synthetic yarn having a low capacity for liquid absorption; the ends of the tubular fabric are stitched closely so that the fabric will lie flat; the fabric is elongated in shape compared to its width and is used to provide a barrier around the edge of a surgical site, particularly in the abdomen, to be held in place by hand or by mechanical retractors to hold back away from the site other internal organs; the interior of the tubular fabric may be provided with a thin flexible liquid impervious sheet and which is held in place by parallel stitching along the length of the fabric.
