Method and device for transferring fluids between sampling tubes

摘要

The present invention is directed to a fluid transfer device including first (12) and second (120) sampling tube holders for accommodating sampling tubes (200,100) therein, with the holders joined together through a coupler (40). The coupler includes a cannula (52,152) having a first end (56) extending into the first sampling tube holder and a second end (156) extending into the second sampling tube holder, thereby establishing a path for fluid flow between a first sampling tube accommodated within the first holder and a second sampling tube accommodated within the second holder through the cannula. The coupler may be a two piece system including two hubs with separate cannulas extending from each hub, and each hub may be separately joined to the holders prior to joining the hubs to form the coupler. The coupler may further include a connector extending between the two hubs.
