FLUID TRANSFER DEVICES HAVING CARTRIDGE PORT WITH CARTRIDGE EJECTION ARRANGEMENT

摘要

Fluid transfer devices for use in manual cartridge filling procedures for filling cartridges with liquid drug dosages from medicament containing vials. The fluid transfer devices include a double ended main body having a longitudinal axis, a vial port for telescopic receiving a drug vial and a cartridge port for slidingly receiving a leading cartridge end. The cartridge port includes a cartridge securing arrangement for releasably securing a leading cartridge end therein and a cartridge ejection arrangement for at least partially ejecting a cartridge therefrom for assisting manual sliding ejection of a filled cartridge. The cartridge port can include either a combined cartridge securing and ejection arrangement or a discrete cartridge securing arrangement and a discrete cartridge ejection arrangement.

1. A fluid transfer device for use with a cartridge and a drug vial for filling the cartridge with a liquid drug dosage, the cartridge including an open ended tube having a leading cartridge end and a trailing cartridge end, the leading cartridge end sealed by a cartridge septum and the trailing cartridge end sealed by a slidable seal, the leading cartridge end having a forwardmost cartridge surface, the drug vial including a drug vial bottle containing a drug component and having a drug vial opening sealed by a drug vial stopper, the fluid transfer device comprising:
a double ended main body having a longitudinal axis and including a vial port for telescopically receiving the drug vial and having a puncturing cannula for puncturing the drug vial stopper for flow communication with the drug vial bottle and a cartridge port having
i) a puncturing needle for puncturing the cartridge septum for flow communication with the open ended tube on manual sliding insertion of the cartridge thereinto towards said vial port, said puncturing cannula being in flow communication with said puncturing needle for enabling a manual cartridge filling procedure for filling the cartridge with the liquid drug dosage,ii) a cartridge securing arrangement for releasably securing the cartridge in said cartridge port on said manual sliding insertion thereinto, andiii) a cartridge ejection arrangement for at least partially ejecting the filled cartridge from said cartridge port for assisting complete sliding ejection of the filled cartridge therefrom.
