UNIVERSAL MEDICATION INJECTION ADAPTER ASSEMBLY FOR USE WITH A NEEDLELESS PHARMACEUTICAL SYRINGE

摘要

A universal medication injection adaptor assembly for use with a needleless pharmaceutical syringe having a distal end terminating in a male Luer connector. A cannula hub having a hub melting temperature has a distal end disposed in a cavity of a cylindrical coupling and a proximal end configured as a female Luer connector for mating with the syringe' s male Luer connector. A mount in the cavity supports the cannula-hub distal end. Ultrasonic energy directors in the internal cavity has an energy-director melting temperature greater than the hub melting temperature. A safety shield extending from the coupling distal end at least partially surrounds a needle cannula having a proximal end extending from the hub distal-end and distal end terminating in an exposed needle tip. The ultrasonic energy directors are embedded in the cannula-hub distal end for fixedly attaching the cannula-hub distal end in the coupling.
