Abstract
The present invention comprehends the provision of a fluid tight holding chamber which accumulates solution from the vial that aspirates during mixing or drawing fluid from the vial or is pressured out of the syringe upon extraction of the cannula from the vial. The holding chamber is defined in conjunction with the vial septum by a shield cap that surrounds and seals to the neck of the vial. The shield cap defines a guide for the cannula of the syringe and directs the cannula through a sealing member, the holding chamber, the septum and into the vial. One aspect of the invention provides a sleeve portion on the shield cap that receives and retains the syringe barrel. An arm is provided on the sleeve portion and has a notch that holds the syringe barrel in a predetermined position during shipment and storage of the assembly.
