Syringe, syringe assembly, and manufacturing method of syringe

A female syringe barrel is disclosed, which includes two protrusions provided on a cylindrical portion. A length (Lp) of each protrusion of the two protrusions along a direction, perpendicular to an axis of the cylindrical portion and perpendicular to a direction in which each protrusion of the two protrusions protrudes from the cylindrical portion, is 2.0 mm to 4.5 mm. A width of each protrusion of the two protrusions along an axial direction of the cylindrical portion is 1.0 mm to 2.1 mm. Each protrusion of the two protrusions has an inclined surface, which opposes a trailing flank of a screw when the two protrusions are engaged into the screw of a lock adapter, in an end portion close to a barrel body.

Female syringe barrel, syringe kit, and syringe connection method

A medical device package includes: a medical device container including a nest which holds a plurality of medical devices (syringes) to be filled with medicine to be aligned in a predetermined direction, a medical device container main body which accommodates the nest, and a sheet-shaped first sealing member which seals the medical device container main body; and a storage container for packing with an outer peripheral surface of the medical device container maintained in a sterile state. The storage container is formed of a storage container main body accommodating the medical device container and having a shape-retaining property, and seals a transfer opening at an upper end of the storage container main body with a sheet-shaped second sealing member having an antibacterial property and air permeability.

Medical device package

A prefilled syringe includes a barrel body, a gasket that seals a proximal end side of a medicine chamber of the barrel body, and a cap that is attached to a tip and seals a distal end side of the medicine chamber. The cap includes a surface area increasing member that extends to the proximal end side, is inserted into a flow path of the tip, and protrudes to the medicine chamber to increase a surface area of a medicine solidified in a lump in the medicine chamber.

Prefilled syringe, syringe assembly, method for manufacturing prefilled syringe, and method for increasing surface area

In a syringe, which is a prefilled syringe, when a cap body is attached to a cylindrical portion, a first sealing section is compressed radially inward by an inner peripheral surface constituting an opening of the cylindrical portion, thereby sealing a distal end section of a flow path in a liquid-tight manner, and a second sealing section is compressed radially inward by an inner peripheral surface of a proximal end section of the cylindrical portion, thereby sealing a proximal end section of the flow path in a liquid-tight manner.

Syringe and prefilled syringe

A syringe barrel includes: a barrel body including a nozzle portion at a distal end thereof; and a cap removably mounted to the nozzle portion and configured to seal a distal end opening of the nozzle portion. The cap includes: an inner cap formed of an elastic material and configured to come in liquid tight contact with the nozzle portion in a mounted state in which the cap is mounted to the nozzle portion, and a cylindrical outer cap formed of a material having a higher hardness than the inner cap and fixed around the inner cap. The inner cap includes: a base portion, and a cylindrical wall extending from the base portion in a proximal direction and surrounding the nozzle portion.

Syringe barrel, method for manufacturing same, and pre-filled syringe

A syringe system includes a syringe and a pressurization device for a syringe. The pressurization device for a syringe is configured so that the plunger advances by a forward rotation of the plunger, and the plunger retracts by a reverse rotation of the plunger. The plunger is advanceable by pressing the gasket at the time of the forward rotation and is retractable with respect to the barrel without pulling the gasket in the proximal end direction at the time of the reverse rotation.

Syringe system and usage method of the same

A female syringe of a syringe kit includes a female syringe barrel including a cylindrical portion into which a nozzle of a male syringe is insertable, a hollow cylindrical packing arranged in the cylindrical portion, and a cap detachably attached to the cylindrical portion. When the cap is detached from the cylindrical portion, the packing remains in the cylindrical portion, a distal end opening is opened, and the nozzle of the male syringe is fitted in a liquid-tight manner to an inner side of the packing.

Female syringe and syringe kit

A syringe assembly includes a prefilled syringe and a cap. A cap body is configured to be displaced from a first position where a viewing portion is positioned in a cylindrical main body to a second position where the viewing portion protrudes in a distal end direction from an opening of the cylindrical main body. When a mounting tube portion of the cap removed from a syringe body is brought close to a nozzle portion of the syringe body, the cap body is pressed in the distal end direction by the nozzle portion, thereby being displaced from the first position to the second position, and the appearance of an outer peripheral portion of the viewing portion changes.

Cap, syringe assembly, and prefilled syringe

A syringe cap is configured to be removably attached to a barrel to seal a needle hole in a puncture needle held by a barrel tip portion of the barrel, and comprises a first member that is configured to be pierced with the puncture needle and that comprises an elastic material having a Young's modulus in the range of 1 to 10 MPa; and a second member that comprises an elastic hollow body having a Young's modulus in the range of 1 to 10 MPa and that is configured form a closed space between the first member and the barrel. A vapor permeability of a material from which the first member is formed is lower than a vapor permeability of a material from which the second member is formed.
