Description
, ' EASY LINKING TRANSFER SYSTEM
FIELD OF THE INVENTION
The present invention relates to a transfer system and more particularly, relates to an assembly for transferring one or more components of a pharmaceutical composition between containers.
BACKGROUND OF THE INVENTION
Typically, a syringe is filled manually by aspirating a liquid pharmaceutical component from a pharmaceutical vial which traditionally has a penetrable closure. The syringe has a needle that penetrates the penetrable closure following which the syringe is typically filled by drawing air into the body of the syringe, aligning the needle with the vial's penetrable closure and inserting the needle through the penetrable closure into the vial.
Subsequently, the vial is inverted and air is forced from the body of the syringe into the vial.
The plunger is then withdrawn to draw out the desired volume of the pharmaceutical component into the syringe and the needle is removed from the vial.
Many pharmaceutical preparations must be distributed and sold as two or more separate components ¨ typically a solid component and a liquid component. They are mixed just prior to administration. In some instances, the two or more components may each be liquid and require mixing prior to administration to the patient.
SUMMARY OF THE INVENTION
It is an object of the present invention to provide an assembly for transferring the contents of a first container to a second container.
According to one aspect of the present invention, there is provided a transfer device comprising a housing having a top, a side wall, an open bottom, the open bottom permitting , , insertion of a vial within the housing, a piercing member mounted within the housing, the piercing member having a piercing tip located at a bottom end thereof, the piercing member having an interior passageway formed therein, a connector located on an exterior side of the top, a moveable member mounted within the housing, the moveable member being moveable from a first position wherein the moveable member prevents access to the piercing tip and a second position permitting access to the piercing tip when the vial is inserted in the housing.
In a large number of cases, the transfer device of the present invention provides for the easy linking of a vial and a syringe whereby the components may be mixed to form a composition in the syringe ready for patient injection.
The contents of the vial may be any suitable pharmaceutical component though in many instances, it will be a dry pharmaceutical component such as a lyophilized product.
However, as previously mentioned, it could also be a liquid component.
The syringe will normally contain a liquid component which is frequently a diluent for the active pharmaceutical ingredient in the vial. The syringe may be any conventional syringe readily available from different manufacturers. Typically, the syringe will contain a piston and have a back stop or finger flange attached to one end thereof. A
plunger rod will be attachable to the piston of the syringe.
One problem with known transfer devices is that access to the needle or plastic spike within the transfer device should be minimized to prevent accidental pricks.
Once such transfer device is shown in International Application PCT/CA2010/001399, the teachings of which are incorporated herein by reference. In the transfer device, a cap is provided to permit access to the syringe side of the device and the luer connection cannot be accessed

until the cap is removed. However, the cap can only be removed when the device is coupled to the vial.
On some occasions, it is deemed desirable to re-use the transfer device. With the aforementioned transfer device, this was not possible as the vial remains secured to the transfer device and both are disposed of as a unit.
On other occasions, it is deemed best practise to not permit re-use of the transfer device due to possible contamination. However, it is still desirable to protect the user from the needle or spike.
In one embodiment of the present invention wherein the device may not be re-used, the moveable member engages the wall of the housing upon upward movement when the vial is inserted into the housing. The rotational movement moves it to an upper position which, when the vial is pulled down, the moveable member moves to a position where it still protects against accidental needle prick but also cannot be moved upwardly again as it is locked position.
In a further embodiment, the moveable member is retracted down to a position from which it started to enable re-use of the transfer device.
