摘要： A mixing device and a retractable syringe comprising same are provided. The mixing device comprises concentric outer and inner barrels that form an outer chamber, the inner barrel having an inner chamber. A mixing plunger is slidably located in the outer chamber. A seal located in the outer chamber is capable of axial movement, in response to depression of the mixing plunger, from a first position in sealing engagement with one or more apertures in the inner barrel to a second position intermediate the apertures and vents in the outer barrel. This allows depression of the mixing plunger to force a first substance from the outer chamber through the apertures to mix with a second substance in the inner chamber. The mixed substance in the inner barrel is then delivered by the syringe with subsequent needle retraction.

摘要： An automatic mixing device, an actuating device removably mounted to the automatic mixing device and a retractable syringe having the automatic mixing device are provided. The actuating device has an initially compressed spring and a trigger member that initiates spring decompression to drive depression of a mixing plunger of the automatic mixing device. A seal located in the outer chamber is capable of axial movement upon depression of the mixing plunger, from a first position in sealing engagement with one or more apertures in an inner barrel to a second position intermediate the apertures and vents in an outer barrel. This allows depression of the mixing plunger to force a first substance from the outer chamber through the apertures to mix with a second substance in an inner chamber of the inner barrel. The mixed substance in the inner barrel is then delivered by the syringe with subsequent needle retraction.
