Embodiment Construction

[0015] Figure 1A shows a syringe 10, a vial 16 and a fluid transfer device 20 for the purpose of fluid reconstitution. The syringe 10 comprises a barrel 11 with a plunger 12 and a syringe tip 13 terminating in a widened distal syringe tip 14 for preventing a conventional injection needle having a female luer from slidingly mounted thereon. Syringe tip 14 has an outer diameter D1 , a length L1 and an annular trailing surface 15 . Syringe 10 includes liquid contents for forming a medical solution in vial 16 . The liquid content may consist of a diluent used to reconstitute a powder or to be mixed with a liquid medicine. Alternatively, the liquid content may include an active pharmaceutical ingredient. The vial 16 includes a body 17A that is open at the top, a vial opening 17B that is plugged by a vial stopper 18 , and a narrow neck 17C intermediate the body 17A and the vial opening 17B. The bottle body 17A has a vial interior 19 that includes a powder or liquid 19 of the drug...

Abstract

A vial adapter for use with a syringe having a widened distal syringe tip, and a medicinal vial. The vial adapter includes a top wall, a skirt for telescopically slidingly receiving the medicinal vial, a downwardly depending puncturing spike, and a syringe port opposite the puncturing spike and in flow communication therewith. The syringe port is formed with at least two upright syringe port members for being initially outwardly flexed on the sliding insertion of the widened distal syringe tip into the syringe port and subsequently snapping behind the widened distal syringe tip on its forced full sliding insertion into the syringe port to retain the widened distal syringe tip in said syringe port.

Description

technical field [0001] The present invention relates to a medical fluid delivery device for use with a syringe having a widened distal syringe tip to prevent a conventional injection needle with a female luer from slidingly mounted thereon. Background technique [0002] Commonly owned PCT International Application No. PCT / IL2005 / 000376 entitled "Liquid Drug Delivery Devices and Needle Shield Removal Device" and published pursuant to PCT International Publication No. WO 2005 / 105014 discloses a drug A liquid delivery device comprising a vial adapter with elastic infusion tubing for preparing a reconstituted medicinal liquid for a syringe with a widened distal syringe tip for immediate administration to a subject. Dimension the widened distal syringe tip to prevent conventional injection needles from slipping over it. The free end of the elastic infusion tubing is intended to extend sealingly over the widened distal syringe tip of the syringe in order to enable fluid transfer ...
