Abstract: An occlusion prevention apparatus for a gastrostomy button system is provided. The apparatus includes an occlusion prevention tube comprised of a corrugated tube. The occlusion prevention apparatus may be in surrounding relation about a gastrostomy extension tube comprised of a flexible tube connecting a feeding bag adapter and a gastrostomy button adapter. The occlusion prevention apparatus may include a slit through the wall of the corrugated tube, which is operative to enable the flexible tube portion of the gastrostomy extension tube to slide into and out of an interior portion of the occlusion prevention tube. The occlusion prevention tube is operative to reduce the occurrences of blockages of nutrition in the gastrostomy extension tube while an individual is sleeping, and thereby reduce the number of audible warnings output by an alarm device monitoring the feeding process.
