Device for carrying syringes

Syringe barrel

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.

Syringe with safety mechanism

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.

Syringe

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 () detachably coupled to a cap () so as to be separated from the barrel () together with the cap () when the connector () is located at an initial position where the connector () is attached to a barrel () via the cap (); and a connector-side engaging part () that engages a barrel-side engaging part () of the barrel () when the connector () is located at an attached position that is closer to a proximal end in an axial direction of the barrel () than the initial position, allowing the connector () to remain attached to the barrel () by being detached from the cap () separated from a nozzle ().
