20100063440 | Liquid Mixing and Injecting Tool - A liquid mixing and injecting device is provided which includes an upper branch tube, a chamber part and a rubber plug including a slit formed through the body of the rubber plug. A lid member is attached to an open end of the upper branch tube. The lid includes an opening part and a generally cylindrical member. The upper branch tube is occluded by the rubber plug. A male luer part of a syringe can be inserted into the slit to access the chamber part. A rubber plug receiving part is provided for controlling the shape of the lower end part of the rubber plug body when it is deformed to avoid forming a gap where air can accumulate within the flow path. The rubber plug is fixed by fixing an upper fixing piece of the rubber plug to the generally cylindrical member and by fixing a lower fixing piece between the opening part and the generally cylindrical member. | 03-11-2010 |
20110046555 | INTERNAL NEEDLE - An indwelling needle is provided which has a simple structure and is capable of securely mounting a needle tip protective tool on the tip portion of an internal needle. The indwelling needle A consists of an external needle | 02-24-2011 |
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 |

20090198256 | ORGANOPEXY TOOL AND ORGANOPEXY KIT - The present invention provides an organopexy tool ( | 08-06-2009 |
20090198257 | ORGANOPEXY TOOL AND ORGANOPEXY KIT - Organopexy tool set (S) is comprised of suturing tool ( | 08-06-2009 |
20100012207 | LIQUID COINFUSION UNIT - A liquid coinfusion unit and processes are provided inside which liquid and air are unlikely to accumulate which consists of a chamber part, a main upstream branch pipe, a downstream branch pipe, a supplementary upstream branch pipe, and a stopcock which can allow communication/block the area between the chamber part and main upstream branch pipe, and the area between the chamber part and downstream branch pipe, respectively. The portion of the liquid flow channel inside the chamber part which runs from the main upstream branch pipe towards the downstream branch pipe consists of a bypass flow channel which extends from the direction of advance of the liquid from the main upstream branch pipe towards the chamber part to one side which is substantially orthogonal to the direction of advance, after which it extends in the direction of advance of the liquid from the chamber part towards the downstream branch pipe. | 01-21-2010 |
20100305586 | Medical Suturing Device - The present invention provides a medical suturing device structured with a retrieval puncturing needle formed with through-hole; a retrieval member able to be inserted through through-hole; an insertion puncture needle formed with through-hole; a hollow tube that can be inserted through insertion through-hole, and the distal tip of which is formed into a deformable bent portion; and a suture that can be inserted through the inside of hollow tube. The retrieval member is structured with an annular engagement member that can be deformed into a straight shape, a rod member that is connected to annular engagement member, and a grip that is provided with a mark. The mark is furnished on hollow tube, such that when retrieval puncturing needle and insertion puncture needle are in a condition where mark and mark are facing each other, the upper supporter and lower supporter can be detachably attached. | 12-02-2010 |

20090031701 | LIQUID COINJECTOR - A liquid coinjector is disclosed which includes a main body having an upstream pipe defining an inlet flow channel in fluid communication with a chamber portion of the body, a downstream pipe defining an outlet flow channel in fluid communication with the chamber portion, and a merging pipe in fluid communication with the chamber portion. A flexible tube supported is in the inlet flow channel of the upstream pipe. The flexible tube facilitates fluid flow from the upstream pipe to the chamber portion. At least one pressing part is positioned adjacent to the flexible tube. The at least one pressing part is movable from a first position to a second position to compress the flexible tube and close the inlet flow channel. | 02-05-2009 |
20090177170 | Closable Male Luer Connector - The present invention provides a closable male luer connector ( | 07-09-2009 |
20100137803 | NEEDLE TIP PROTECTOR - The present disclosure is directed to an indwelling needle set which includes a needle tip protector device which adds a minimal length to the needle set to maintain operability of the device. To accomplish this, a needle tip protector device is provided for releasable attachment to the needle set. The protector device includes a body and a protecting sleeve which is movable through an opening in the body from an advanced position located substantially within the body to a retracted position extending rearwardly from the body. The protecting sleeve is dimensioned to slidably receive a puncturing needle which includes an increased diameter position which cannot be withdrawn through the protecting sleeve. | 06-03-2010 |
