20110319821 | 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 be 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. | 12-29-2011 |

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 |
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 |
