A stent having a cylindrical peripheral wall formed with a line-shaped body that extends in a helical form in a circumferential direction while reciprocating in an axial direction at a given amplitude. In the stent, connecting parts are formed to link portions of the line-shaped body that are adjacent in the axial direction, and a friable part is provided to rupture itself by being implanted in the somatic lumen and release a link made by the connecting parts.

Abstract: A connection device includes a main holder including a syringe holder to be attached to a syringe and a cannula holder which includes a double-head cannula. The cannula holder is located at a retracted position retracted with respect to the syringe holder in the pre-use state, and is advanced to an advanced position abutting on the syringe holder in the use state. The connection device further includes a separation preventing mechanism which engages the syringe to prevent separation of the syringe from the syringe holder in the state where the cannula holder is located at the retracted position. When the cannula holder is located at the advanced position, the separation preventing mechanism releases an engagement state with the syringe to permit the separation of the syringe from the syringe holder.

Abstract: A needle tip protector is configured in such a manner that a flexible plate is provided to a protector main body over which an action ring is mounted and that the flexible plate undergoes flexural deformation when the action ring is moved to a predetermined position relative to the protector main body. When the flexible plate undergoes flexural deformation, a needle tip of an inner needle to which the protector main body is mounted is protected by a protection part placed at a distal end of the flexible plate. The needle tip protector is also provided with a slip-stop mechanism for preventing the action ring from slipping out of the protector main body in an axial direction of the needle.

Abstract: A bottomed, tubular hollow elastic body that opens toward an outlet side of a drug solution flow path is accommodated and arranged in an accommodation part formed in a housing, and a middle protrusion is provided protruding toward an inlet side of the drug solution flow path from a center part of a bottom wall of the hollow elastic body. Insertion of a male luer causes the bottom wall of the hollow elastic body to be elastically deformed so as to enter inside a peripheral wall, increasing the volume of the drug solution flow path, which is formed between an outer surface of the hollow elastic body and an inner surface of the accommodation part. Removing the male luer and canceling the elastic deformation of the hollow elastic body causes the volume of the drug solution flow path to be reduced.

Abstract: To provide a drug solution preparing kit which can be handled with ease in a substantially aseptic manner, and has no risk that a leakage of a drug solution such as a splash and a dispersion of an aerosol to an ambient environment occurs upon preparation of the drug solution There is provided a drug solution preparing kit including a pre-filled syringe and a transfusing tool, wherein the pre-filled syringe includes a sealing member which seals the tip end and can not be removed from the tip end, and that the transfusing tool includes a one-way valve which can discharge only gas from the system in an irreversible manner, and a filter which is provided so as to adjoin to the second communication channel with respect to the one-way valve.

Abstract: A bottle-type blow-molded plastic infusion container that can be set in an upright position. When liquid is discharged from the container, almost no dead space occurs in shoulder and bottom portions (required amount of air to be placed in the container to remove residual liquid is less). The blow-molded container has a mouth section (1), a neck section (2), the shoulder section (3), a barrel section (4), and the bottom section (5). The barrel section (4) has a pair of broad side faces (41, 41) and a pair of narrow side faces (42, 42). The bottom section (5) is formed in a shape symmetrical about a longitudinal axis of the bottom section (5) and bent inward in a V shape. Further, the shoulder section (3) has a pair of broad side faces (31, 31) and a pair of narrow side faces (32, 32). In the narrow side faces (32, 32) are formed grooves (33, 33) symmetrical about a longitudinal axis and bent inward in a V shape.

Abstract: A plurality of heat transfer pipes have a circumferential portion arranged at a short distance from an inner surface of a heat exchanger case while they are bundled to form a pipe group and a first chord which retracts toward a center in a direction of cylinder diameter from an arc formed by the circumferential portion. The plurality of bundled heat transfer pipes are loaded in the exchange case such that the first chord and an inner surface of the heat exchange case on a side where a heat exchange medium inlet port is attached are opposed to each other. By making a flow of a heat exchange medium to each heat transfer pipe uniform, a heat exchanger capable of obtaining high heat exchange performance is obtained.

Abstract: A nasal cavity administration container includes a body section including a medical fluid storage section having an opening and a plunger having a pressing part, and a plunger moving amount regulation member having a stopper and being engaged with the body section, an engagement with the body section being relieved only in a state where the pressing part abuts on the stopper. When the plunger is pushed into the medical fluid storage section, the plunger moves forward until the pressing part abuts on the stopper. The plunger is further pushed into the medical fluid storage section with the plunger moving amount regulation member detached from the body section. The nasal cavity administration container can administer a medical fluid easily and appropriately.

Abstract: A liquid medicine self-administration device including a flexible reservoir, an operating member, a pushing member to move with respect to the operating member and to induce pressure deformation of the reservoir, and engaging means engages the operating member. With the operating member engaged by the engaging means, the pushing member is relatively moved to the operating member based on restoring force of a spring member to push the reservoir by the pushing member. By disengaging means moving in unison with the pushing member, the engaging means is released from an engaged state with respect to the operating member, when the pushing member has moved to a predetermined location while pushing the reservoir.
