Abstract: The male connector of the present disclosure allows for the flow of fluids therethrough and includes a movable blunt needle having a shoulder projecting radially outwards from the movable blunt needle. The male connector also includes an outer cylinder body formed around the movable blunt needle and disposed in coaxial alignment to the movable blunt needle, a blunt needle retainer which retains the movable blunt needle so that the movable blunt needle can move in an axial direction, and a valve which opens as a result of the movable blunt needle moving in the axial direction when the posterior end presses against the valve. This occurs when the movable blunt needle is inserted into a corresponding connection site, such as a female connector, and the shoulder presses against the connection site to force the movable blunt needle in the axial direction.

Abstract: A device for checking indwelling site capable of checking the indwelling site of a medical tube through multiple checking operations by simple techniques using a single device is disclosed. The device for checking indwelling site is provided with a barrel, a first plunger having a torso member and a hole formed communicating between the inner cavity of the torso member and the inner cavity of the barrel and disposed capable of pushing into or pulling out while keeping the barrel airtight, a second plunger having a second tip member and disposed capable of pushing into or pulling out while keeping the torso member airtight, a space formed between an inner wall and the tip face of the first tip member and designed to suck the gas fraction of the fluid sucked into the barrel into the torso member, and a detecting member arranged inside the torso member on the tip side of the second tip member and designed to react with carbon dioxide sucked in through the space by discoloring.

Abstract: Disclosed is a connector cap which can suppress leakage of fluid, and a transfusion line connection apparatus for use with the connector cap. The connector cap includes a container having a first opening and a second opening; a seal member disposed in the first opening so as to separate the inside and the outside of the container, the seal member including an insertion passage formed therethrough whereby an injection tube of a male connector can be inserted from the outside to the inside of the container; and a hydrophobic filter which is disposed in the second opening.

Abstract: A syringe comprising a clear syringe barrel, a clear hollow plunge which can be pushed and pulled within the syringe barrel and is open at both ends, a gasket having a throughhole for providing communication between the inside of the plunger and the inside of the syringe barrel and provide a fluid tight seal with the syringe barrel, and a return-flow prevention mechanism which allows the fluid flowing into the plunger to flow in an outward direction from the inside of the plunger.

Abstract: The male connector of the present disclosure allows for the flow of fluids and includes a movable blunt needle having a shoulder projecting outwards from the movable blunt needle and extending proximally from the movable blunt needle. The male connector also includes an outer cylinder body formed around the movable blunt needle and disposed in coaxial alignment to the movable blunt needle and a movable blunt needle retainer which retains the movable blunt needle is movable in an axial direction and a valve which opens as a result of the movable blunt needle moving in the axial direction where the posterior end presses against the valve to open the valve. This occurs when the movable blunt needle is inserted at the destination of the connection in a status where the inlet of the flow channel side of the movable blunt needle is open and such that the shoulder presses against the destination of the connection.

Abstract: A tube for use in gastrointestinal tract which allows administration of nutritional, medicinal, or other agent into gastrointestinal tract while preventing detention of digestive juices in esophagus, and which also prevents reflux of gastric contents. A detention-proof lumen is provided in tube body 12 of gastrointestinal tract tube 10 furnished with tube body 12 equipped with main lumen 12b and expansion lumen, such as balloon lumen 12c, and with an expander such as balloon 15 expanded by delivery of liquid or gas via the lumen provided on outer circumferential surface of tube body 12. Said detention-proof lumen communicates from a part more toward the base than the part where expander is provided on outer circumferential surface of tube body 12 to a part more toward the tip than part where the expander is provided on outer circumferential surface of tube body 12. An inner tube 18 used for liquid supply is provided movably within tube body 12.

Abstract: A connection structure of a transfusion line includes: an injection tube including a bottomed tubular injection part having an opening in the leading end side circumferential wall, and an introduction part communicating with the inside of the injection part; a bottomed outer tube part having a bottom portion linked to the injection tube part and opened to the leading end side for fitting a mating member therein; and a protective shutter externally inserted on the injection part for closing the opening and adapted to move along the axis of the injection part, when it receives a pressing force not lower than a predetermined level toward the base portion side, thereby to open the opening, and to return to the leading end side, when the pressing force is released, thereby to close the opening.

Abstract: A sealable access stopcock includes a valve body having a switching part formed in a valve shaft thereof for switching from one flow passage to another; and a main body having an internal chamber in which the valve shaft of the valve body is rotatably fitted, and a plurality of tributary tubes each having a lumen extending therethrough, the lumen opening on a side wall of the internal chamber; the valve body being rotated to selectively bring the lumens into communication with one another through the switching part and thereby switch flow of an infusion fluid from one flow passage to another. A switching channel is provided in the form of an arcuate groove in the switching part of the valve shaft to extend along the circumferential surface thereof.

Abstract: In a glass-tube fuse comprising a glass tube, conductive caps on opposite ends of the tube and a fuse element enclosed in the tube and connected between the caps, the fuse element comprises a plurality of cores extending between the caps and at least one braiding strand of metallic material coiled alternately around the cores in opposite directions and connected at its ends to the end caps.
