Device for the bidirectional transfer of a liquid between a vial and a carpule
First Claim
1. Device for the bidirectional transfer of a liquid between a vial (14) equipped with a puncturable stopper (28) and a carpule (12) comprising a cylindrical reservoir (25) in which slides a puncturable piston (27), said device comprising:
- a body (16) having means (18) for fastening on the vial (14);
a hollow needle (24) featuring a first extremity (24B) for puncturing the piston (27) of the carpule and a second extremity (24A) adapted for puncturing the stopper (28) of the vial;
a moving element (20) which is displaceable with respect to the body (16) along the axis of the needle (24), said moving element (20) having means for constraining the reservoir (25) of the carpule to move axially along the axis of the needle (24); and
a distance sleeve (22) interposed between the body (16) and the puncturable piston (27) of the carpule, said distance sleeve (22) forming a limit stop for the puncturable piston (27) with respect to the body (16), characterized in that the hollow needle (24) is rigidly joined to the body (16) and is axially fixed with respect to the body (16).

Abstract
A device for bidirectional transfer between a vial and a carpule. The device having a body fastened to the vial, a hollow needle, a moving element which is displaceable with respect to the body along the axis of the needle, a carpule reservoir constrained to moved axially in the direction of the axis of the needle, and a distance sleeve interposed between the body and the puncturable piston of the carpule. The distance sleeve forms a limit stop for the puncturable piston with respect to the body. The hollow needle is rigidly joined to the body and is axially fixed with respect to the body.
