Abstract: PURPOSE: To stabilize the supply of a kind in a gastrostomy forming tube. CONSTITUTION: This gastrostomy forming tube has a triangular holding element of which the top points are rounded and also has three elastic petaloid flanges 27, 28, 29 extending in a diameter direction. The petaloid flanges 27, 28, 29 and a tube body 21 are made of differenet materials. Substantially, triangular connection points are present between the connection points of the petaloid flanges. The petalloid flanges are made low in flexibility as compared with the connection points by changing a material or thickness.

Abstract: PURPOSE: To administer liquid such as an intestinal aliment and medicines into a stomach and the small intestine by providing a first opening part in a flexible tube, providing a second opening in an expander, and setting a diameter of the first opening part larger than a diameter of the second opening part. CONSTITUTION: A basic constitutive part of a device 10 is composed of a flexible tube 11, a joining tube 12 having a locking part to constitute a connecting part and a tapering expander 13. A first opening part 15 is provided on the base end of the device 10, and a second opening part 18 is provided on the tail end, and a diameter of the first opening part 15 is set larger than a diameter of the second opening part 18. The first opening part 15 exists on one end of the flexible tube 11, and the second opening part 18 exists in a tip part of the tapering expander 13. Therefore, a large-sized gastric fistula forming nutrition replenishing tube is not only durable but also relieves clogging by facilitating administration of a crushed medicine. A treatment by another endoscope is not necessary to remove the installed nutrition replenishing tube.
