초록 ▼

Syringe assembly apparatus and associated methods are provided for use in dispensing viscous materials, such as dental compositions, in a controlled fashion. The preferred embodiment of the syringe assembly of the present invention includes a syringe body of conventional fashion, having a passageway therethrough and a discharge port communicating with the passageway. An adapter member is provided which nests within the syringe body passageway, the adapter member having a bore passing through the length thereof for receiving a viscous material to be dispensed. When the adapter is nested within the passageway of the syringe body, the bore communicates with the discharge port of the syringe body. An important feature of the invention is that the bore has a diameter substantially the same as the diameter of the discharge port at the location where the discharge port communicates with the bore. The assembly of the present invention also includes a plunger member for ejecting viscous material contained within the bore through the discharge port of the syringe body. The present invention is also directed to adapter members for use with conventional syringes.
