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 male luer connector to prevent generation of bacteria and waste of medicinal liquid. The male luer connector comprises a basal end and a tip end rotatable relative to the basal end; the male luer part is tapered and rotatable within the tip end. The outer peripheral surface of the tip end is decreased from the rear side to the front side; and a stick-like male luer occluding portion is provided within the male luer part which can tightly occlude liquid from the tip end opening of the male luer part. An internal thread portion is provided on the inner peripheral surface of the basal end and an external thread, helically engaged with the internal thread, is provided to the rear end portion of the male lure, whereby the tip end opening can be opened or closed by rotating the tip end relative to the basal end.

Abstract: The invention is directed to a connection structure that can minimize the formation of cracks of a connector or leakage of liquid. In the structure, a female thread (34) formed on the inner peripheral surface of lock ring (28) in a male connector (22) engages a male thread (25) on the outer peripheral surface of a female connector (21) when the male connector and the female connector are screwed to each other. Further, protrusion strips (26a), (26b) are formed on the rear side portion of the male thread on the outer peripheral surface of female connector, and notches (35a), (35b) that can engage with said protrusion strips are set on the tip portion of lock ring (28). As a result, when the male thread and the female thread are screwed to each other, the screwed state is appropriate when protrusion strips and notches are engaged with each other.

Abstract: An infection-preventing gastrostomy catheter kit to be used in the gastrostomy, which can pass an intragastric retainer of a catheter easily and reliably through an infection-preventing sheath by an easy maneuver, and which can reduce the diameter of the infection-preventing sheath. The catheter kit comprises: a gastrostomy catheter 20 including a flexible, hollow PEG tube 21 reinforced with filaments 24, an deformable intragastric retainer 23 positioned at the trailing end of the PEG tube 21, and a tapered member 22 positioned at the leading end of the PEG tube 21 for retaining the leading end portion 40a of a guide wire 40 inserted from a leading end hole 22a thereof; and an infection-preventing sheath 1 including a flexible, hollow tubular body 2, and a socket member having a socket 4 positioned at the trailing end of the tubular body 2 for retaining the intragastric retainer 23, and pins 5, thereby removably sheathing the gastrostomy catheter 20.

Abstract: A connector for switching communication-to-interception states between liquid transfusion tubes. The connector comprises a connector body, a seal member, and a valve with an improved sealing which limits contact with air and minimizes generation of bacteria during medical use.

Abstract: A medical suturing tool 10 is composed of an insertion puncture needle 13 having an insertion hole 13a, a retrieval puncture needle 14 disposed in parallel with the insertion puncture needle 13, a lock part 15, and a surgical suture 16. A vertically elongated opening 18 is formed on the side surface of the insertion puncture needle 13, and an engaging groove 19 including a wide upper portion 19a and a narrow lower portion 19b on the side surface of the retrieval puncture needle 14 at a position slightly lower than the portion opposing to the vertically elongated opening 18. The lock part 15 is composed of a spherical portion 15a which can pass through a wide upper portion 18a and cannot pass through a narrow lower portion 18b and a rod-shaped portion 15b which can pass through the narrow lower portion 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 liquid mixing infusor includes a main body defining an internal chamber and has an upstream port, a downstream port and a confluent port. Each port is fluidly couplable with the internal chamber. A valve may be mounted within the internal chamber of the main body and is adapted for rotational movement between a blocking position interrupting fluid flow between the confluent port and one of the upstream port and the downstream port and between the upstream port and the downstream port, and a flow position permitting fluid flow between the upstream port and the downstream port. A manually manipulative member is mounted relative to the main body and operatively connected to the valve. The manipulative member is movable to cause corresponding movement of the valve between the blocking position and the flow position.

Abstract: A liquid co-infusion device has a plurality of connection ports. The device includes an operating part axially movable within a chamber of the device so as to selectively isolate one of said connection ports from the chamber. An end of the operating part may include a groove or through channel movable to cause such isolation. Preferably, the axial movement of the operating part is guided so as to include a axial movement stop.

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.

Abstract: The present invention is directed to a connector with which negative pressure in the channel space in the connector can be prevented during luer removal, in a closed-system connector. A slit (49) is furnished in valve body (40) of three-way stopcock (100). During luer access and luer removal, first and second moving parts (M1and (M2) to the left and right of slit (49) enter and withdraw from first and second valve body accommodating chambers (51) and (52), respectively. First and second valve body accommodating chambers (51) and (52) are formed outside of channel space (S), so the operation whereby first and second moving parts (M1) and (M2) enter and withdraw during luer access and luer removal does not affect the change in volume of channel space (S) and negative pressure can be prevented from occurring in channel space (S) by the aforementioned entry and withdrawal.

Abstract: 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.

Abstract: A connector, for example a Luer connector, has a sealing element such that when a connection is made to the connector, the sealing element is displaced into the connector, opening a fluid flow channel through the connector. The sealing member may include a slit on a lower surface thereof to ease the displacement of the sealing member.
