Abstract: A syringe and a syringe set are provided. The syringe can be readily distinguished from other syringes only by viewing a tip of the syringe. The syringe includes a tip provided at an end of a barrel body to be filled with a medicine and having an outer diameter of 4.315 mm to 6 mm, a peripheral wall provided around the tip concentrically with the tip, and a helical rib formed on an inner the of the peripheral wall or an outer face of the tip.

Abstract: An object is to provide a syringe that is capable of preventing a cap from being mounted to a syringe body at an oblique angle. The cap includes an elastic cylindrical body for receiving an injection needle therein and sealing a holding part, and an external cylindrical body for covering the circumference of the elastic cylindrical body and holding the elastic cylindrical body in such a manner as to prevent movement of the elastic cylindrical body. The external cylindrical body includes an opening part having a dimension configured to be larger than the holding part of the syringe body, and a guide part that guides the injection needle toward a certain direction by coming into contact with a part of the syringe body when the injection needle is received inside the elastic cylindrical body.

Abstract: Provided is a barrel with needle including: a barrel body; and an injection needle, wherein the barrel body has a cylindrical body wall, and an end wall through which the injection needle is inserted, and the inner wall surface of the end wall expands in a direction intersecting the axial direction of the body wall and inclined toward the other opening side of the body wall, with a specific position between an outer circumferential edge and an inner circumferential edge on a proximal end surface of the injection needle serving as a starting point.

Abstract: Provided is a syringe cap including a projection extending in the circumferential direction of a cap body, wherein the projection includes an apex located radially outward of the cap body from the outer circumferential surface of the cap body, a first inclined surface having a starting end located at the apex and having a terminal end located at a position on the side closer to the proximal end of the cap body than the starting end is, and a second inclined surface having a starting end located at the apex and on the outer circumferential surface of the cap body having a terminal end located at a position on the side closer to the distal end of the cap body than the starting end is, on the outer circumferential surface of the cap body, and the shortest distance from the starting end to the terminal end of the first inclined surface is smaller than the shortest distance from the starting end to the terminal end of the second inclined surface.

Abstract: A barrel with a cap, a pre-filled syringe, and a cap with a connector that accommodate connection-receiving bodies of the Luer lock type and of the slip-in type, are provided. Some versions include: a connector (3) detachably coupled to a cap (2) so as to be separated from the barrel (1) together with the cap (2) when the connector (3) is located at an initial position where the connector (3) is attached to a barrel (1) via the cap (2); and a connector-side engaging part (33) that engages a barrel-side engaging part (13) of the barrel (1) when the connector (3) is located at an attached position that is closer to a proximal end in an axial direction of the barrel (1) than the initial position, allowing the connector (3) to remain attached to the barrel (1) by being detached from the cap (2) separated from a nozzle (11).

Abstract: Provided is a syringe with which it is possible to hold with greater stability a liquid inside the barrel while maintaining the slidability and air-tightness between the barrel and the gasket without requiring fixation of silicone oil, and which is excellent in terms of accuracy of visual inspection. The syringe has a resin barrel, a gasket slidably inserted inside the barrel, a plunger attached to the gasket, and a silicone film obtained by applying silicone oil having a kinematic viscosity of 500 to 10,000 cSt over the inner peripheral surface of the barrel in an amount of 5 to 50 ?g per 1 cm2 of area.
