Abstract

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.

Claims

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, the vial port 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, and

iii) a cartridge ejection arrangement for at least partially ejecting a filled cartridge from said cartridge port for assisting complete sliding ejection of the filled cartridge therefrom.

2. The device according to claim 1 wherein said cartridge securing arrangement and said cartridge ejection arrangement are formed as a combined cartridge securing and ejection arrangement said combined cartridge securing and ejection arrangement having at least one lever member, each of said at least one lever member having a leading lever member end and a trailing lever member end correspondingly adjacent to and remote from said vial port,

each of said at least one lever member being pivotal on said double ended main body at said leading lever member end for being manually levered from an initial cartridge insertion position co-directional with the longitudinal axis for enabling said manual sliding insertion into said cartridge port to a cartridge ejection position for said at least partially ejecting the filled cartridge from said cartridge port.

3. The device according to claim 2 wherein said combined cartridge securing and ejection arrangement includes a pair of opposite elongated lever members co-directional with the longitudinal axis and dimensioned for guiding said manual sliding insertion of the cartridge into said cartridge port.

4. The device according to claim 3 wherein said pair of opposite elongated lever members extend midway along the cartridge in said initial cartridge insertion position and said trailing lever member end of each lever member of said pair of opposite lever members includes an outward transverse directed finger support for enabling use of the fluid transfer device in a similar manner as a syringe.

5. The device according to claim 2 wherein said cartridge port is elongated and dimensioned to extend midway along the cartridge on said manual sliding insertion therein and formed with a pair of opposite outward transverse directed finger supports for enabling use of the fluid transfer device in a similar manner as a syringe.

6. The device according to claim 1 wherein said cartridge ejection arrangement includes at least one cartridge ejection member biased into a primed state on said securing the cartridge in said cartridge port whereupon, on manual releasing said cartridge securing arrangement, said at least one cartridge ejection member at least partially ejects the cartridge from said cartridge port.

7. The device according to claim 6 wherein said cartridge port is elongated and dimensioned to extend midway along the cartridge on said manual sliding insertion therein and formed with a pair of opposite outward transverse directed finger supports for enabling use of the fluid transfer device in a similar manner as a syringe.
