The present invention comprehends the provision of a fluid tight holding chamber which accumulates solution (1) from the vial that aspirates or is pressured out of the vial upon extraction of the cannula from the vial or (2) is aspirated from the syringe before the cannula is removed from the holding chamber. The holding chamber is defined in the neck of the vial by an insert. The insert may be one piece or two piece and has an inner end sealing the contents of the vial from the holding chamber and an outer end sealing the aspirated medicament in the holding chamber. The insert has a luer seal for sealing against the luer connector on the syringe during the practice of certain procedures.

In combination: a vial having a mixing chamber and a neck for containing a fluid supply and an opening in the neck for gaining access to the mixing chamber; an insert extendible through said opening and providing a sealed holding chamber at least partially within said neck; and means for securing the insert to the vial to prevent separation therefrom and so that the insert seals the vial against the escape of fluid from the mixing chamber, whereby the cannula of a syringe can be extended through the insert to establish fluid communication with the mixing chamber, and upon removing said cannula from the insert, aspirating fluid from the mixing chamber and from the syringe is substantially confined in the holding chamber to prevent exposure by the user to the fluid.
