Abstract: A gastrostomy tube extension device used for inserting or taking out the gastrostomy tube into/from the hole on the patient includes a rod, a fixing member, and an engaging member. The rod is formed of a rod-shaped member, and may be formed with engaging stepped portions on the proximal portion thereof. The fixing member is adapted to be capable of moving along the longitudinal direction of the rod, and an engaging projection which can be fixed to the tube member is formed on the peripheral surface of the fixing member. The engaging member includes a lower engaging portion engageable with the engaging projection and an upper engaging portion which is engageable with the engaging stepped portion. This assembly allows the extension to be locked, allowing the operator to manipulate the device with a single hand.

Abstract: A tube for use in gastrointestinal tract which allows administration of nutritional, medicinal, or other agent into gastrointestinal tract while preventing detention of digestive juices in esophagus, and which also prevents reflux of gastric contents. A detention-proof lumen is provided in tube body 12 of gastrointestinal tract tube 10 furnished with tube body 12 equipped with main lumen 12b and expansion lumen, such as balloon lumen 12c, and with an expander such as balloon 15 expanded by delivery of liquid or gas via the lumen provided on outer circumferential surface of tube body 12. Said detention-proof lumen communicates from a part more toward the base than the part where expander is provided on outer circumferential surface of tube body 12 to a part more toward the tip than part where the expander is provided on outer circumferential surface of tube body 12. An inner tube 18 used for liquid supply is provided movably within tube body 12.

Abstract: A gastrostomy tube extension device which can facilitate insertion or removal of a gastrostomy tube by making the degree of extension of the gastrostomy tube constant. A gastrostomy tube extension device used for inserting and taking out a gastrostomy tube into/from a hole formed on a patient's abdomen, the gastrostomy tube including an outer fixing member to be installed on the skin surface side, an inner fixing member installed on the inner surface side of the stomach wall, and a tube member for connecting the outer fixing member and the inner fixing member and the gastrostomy tube extension device comprising a rod and an engaging member. The rod has a rod-shaped member which can push the center of the distal end of the inner fixing member with its distal portion toward the distal end, and with a plurality of engaging step portions formed on the proximal portion.

Abstract: An organ-fixing instrument and a gastric fistula catheter able to accomplish proper suturing reliably and through a simple procedure. An organ-fixing instrument 10 is structured by a transversely elastic, cylindrical sheath 12, and a body surface installation part 11 attached to the base part of the sheath 12. In the body surface installation part 11 there are provided a through-hole 13 communicating with the sheath 12 and a pair of needle through-holes 14, 15. The sheath 12 is structured by a web-shaped covering part 16 made from a resin, a plurality of reinforcing parts 17 provided at the base end portion of the covering part 16, and skeletal parts 18a, 18b provided at the tip portion of the covering part 16. A suturing thread catch 18 projected in an axial direction by compression in the axial direction is structured by the tip side portion of the covering part 16 and the skeletal parts 18a, 18b.

Abstract: A liquid coinjector is provided in which one or more connection ports may be connected to an outlet port and in which a valve body is provided for selecting the connection arrangement, the valve body being movable in an axial direction within a chamber of a main body.

Abstract: A cap for a connector which can fill a male luer connector with only a fluid, such as a medicinal fluid, without leaving gas in the male luer connector. The cap for the connector comprises the cap body, the sliding part movable relative to the cap body, and the air filter placed at the tip end opening of the gas flow path forming part included in the sliding part. Also, the cap body comprises the cylindrical fitting part for liquid tightly fitting with the tip end opening of the male luer connector, and the cylindrical guide provided with the liquid outlet on its peripheral surface. Further, the liquid outlet can be opened or closed by shifting the gas flow path forming part within the cylindrical guide. Moreover, the cylindrical guide is placed within the recess portion to be guided between the gas flow path forming part and the containing wall.

Abstract: A connector has a connection port closed by a sealing member. The connection port is attached to a first body portion which in turn is connected to a second body portion by an elastic bellows. When a Luer connector is withdrawn from the port, the bellows first extends and then retracts creating an overpressure within the connector.
