20080199558 | Liquid Co-Injection Apparatus - A liquid co-injection apparatus comprising a high-pressure resistant rubber plug capable of obstructing a slit when the chamber is under a high hydraulic pressure. The main body of the liquid co-injection apparatus comprises a chamber part, a downstream branch-tube extending from the chamber part in different directions, an upstream branch-tube, and a connection opening with an attached lid. A rubber plug is attached to the inside of the lid to allow obstruction of the lid when the slit of the rubber plug is closed, and to allow communication between the insides of the chamber part and the connecting tube when the connecting tube is inserted into the slit. Moreover, a rib is provided on the outer peripheral surface of the rubber plug to allow the rubber plug to be strongly drawn and pressed onto the inner peripheral surface of the lid member, further securing the obstruction of the slit. | 08-21-2008 |
20080208132 | Indwelling Needle - An indwelling needle for reducing the deterioration of the valve by the pressure force of the elastic member. | 08-28-2008 |
20080269781 | Surgical Fastener, Surgical Fastener Kit and Removing Tool - The present invention provides an organ fixture having a rod shaped anchoring portion formed by bundling a suturing thread, and a fixing portion made of a suturing thread continuous with the suturing thread of the anchoring portion. By pulling the fixing portion with respect to the anchoring portion with a force larger than a prescribed level, the suturing thread forming the anchoring portion can be loosened. Additionally, the invention provides a type of organ fixture set which pierces and is inserted into the body of the patient while a portion of an anchoring portion and a fixing portion of the organ fixture is accommodated in it, and it can be pulled from the body of the patient while the anchoring portion is left within the stomach wall. Further, the organ fixture set has a unit for removing the organ fixture from the body of the patient. | 10-30-2008 |
20080300542 | Male Luer Connector - Certain embodiments of the present invention include a male luer connector having a valve arrangement for keeping a passage that extends through the male luer connector closed when the male luer connector is not attached to a corresponding female luer connector. This passage of the male luer connector may opened by connecting the male luer connector to a female luer connector. The valve arrangement of the male luer connector may include a movable sealing element arranged around a central fluid conduit. In some embodiments, the male luer connector may include a filter that is permeable to gas, but substantially impermeable to liquid, thus allowing gas to be purged from the male luer connector while substantially preventing liquid from leaking from the connector at least when the male luer connector is not connected to a female luer connector. | 12-04-2008 |
20080319401 | Stopcock Valve - A medical stopcock which allows easier switching operation of plural branch-tubes. The main body of the stopcock comprises a chamber part with a nearly spherical inner surface, and an upstream branch-tube, a downstream branch-tube and a merge-branch-tube all extending from the chamber part. A valve body of the stopcock comprises a nearly spherical valve main body and a rod-shaped operating part with a guide hole linking the inner surface of the chamber part to the outside. In operation, the rod-shaped operating part is moved along the guide hole through the use of the horizontal flow passages and the vertical flow passage to allow the predetermined branch-tubes out of the upstream branch-tube, the downstream branch-tube and the merge-branch-tube to communicate with one another or to shut-off the communication. | 12-25-2008 |
20090062775 | CONNECTING STRUCTURE FOR A CONNECTOR - A connecting structure for a connector in which a male-side connector and a merging pipe are connected by screwing together a female screw having protrusions formed on the inner peripheral surface of a lock ring and a male screw comprising protrusions formed on the outer peripheral surface of the merging pipe is provided with engaging recess parts on the female screw and engaging projections on the outer peripheral surface of the merging pipe which are able to engage with the engaging recess parts whereby when the male screw and the female screw are screwed together to reach an appropriate screwed state, the engaging protrusions engage with the engaging recess parts. | 03-05-2009 |
20090062776 | LOCKING CONNECTOR - A locking connector consists of a male luer part, a connecting support part provided at the rear end of the male luer part of which is connected to a tube, a lock ring supported on the connecting support part in a state in which it is prevented from being withdrawn from the tip end of the male luer part, guide protrusions extending from the tip end side to the rear end side of the connecting support part while steadily curving in the axial direction of the connecting support part and formed on the outer peripheral surface of the connecting support part, and recess parts allowing the entry of the guide protrusions formed on the inner peripheral surface of the lock ring, wherein when the guide protrusions are positioned inside the recess parts, the lock ring can be moved to the tube side from the connecting support part. | 03-05-2009 |
20090287157 | FISTULA CATHETER AND FISTULA CATHETER SET - A fistula catheter with a simple structure and with which it is possible to suppress irritation of the wall of the alimentary canal, and a fistula catheter set. A fistula catheter ‘A’ which is fitted in fistulae formed in a patient's abdominal wall and stomach wall consists of an external retention part which is disposed on the abdominal wall surface side of the fistula, and a tubular part. The tubular part is arranged such that the base end part thereof links with the external retention part, and the tip end part thereof extends from the fistulae into the stomach. The tubular part is formed as a flexible helix. Furthermore, the tip end part of the tubular part projects to the inner periphery of the helix. In addition, the angle between the central axis ‘a’ of the external retention part and the central axis ‘b’ of the helical tubular part is set to be smaller than a right angle. | 11-19-2009 |

20120078192 | FISTULA CATHETER - A fistula catheter which allows a supply tube to be easily connected to a body-external fixing member positioned on the body surface side, and which is only slightly invasive for a patient is provided. The fistula catheter | 03-29-2012 |
20130035668 | CLOSABLE MALE LUER CONNECTOR - A male luer connector is disclosed, the male luer connector being attached to a first tube and connectable to a female luer connector for providing a flow channel from said first tube to said female luer connector. The male luer connector includes a male luer part, which includes a tapered outer peripheral wall, a side wall, and an outlet opening. A tube member is also provided, the tube member having a flow channel therein. The tube member has openings at first and second ends thereof, the first end being movably inserted into an inner space of the side wall and the second end being connected to the first tube. The tube member further includes a male luer part sealing arrangement for sealing the outlet opening. | 02-07-2013 |
