Abstract:
1. A system for connecting a a syringe unit to a port, said system comprising: a syringe unit having a syringe body and a luer part disposed at a first axial position, the syringe body having a plunger and a first engaging portion disposed on an outer peripheral surface thereof, the first engaging portion being separated from the luer part; and a connector configured to be externally disposed at the luer part and extending from the syringe unit, and including a second engaging portion configured to engage the first engaging portion disposed on the outer peripheral surface of the syringe body, such that the engagement of the second engaging portion with the first engaging portion substantially prevents movement of the connector relative to the syringe body, when engaging the first engaging portion, the second engaging portion is disposed in a second axial position on the syringe body such that the second axial position is not disposed along the same radial plane as the first axial position, wherein engagement of the first and second engaging portions is released when an external force is applied, according to a predetermined operation, to one of the connector and the syringe unit in a direction different from a syringe axial direction, and wherein the first and second engaging portions are configured and arranged to enable the luer part to be removably attached to the connector so as to enable selective discharge of medication through the port.
