Abstract:
In a syringe system for mixing a two-component composition, an adaptor for enabling mixing of the two materials in the two-component composition by introducing the material held by one syringe into the other and then repeatedly transferring the mixture back and forth between the two syringes, the adaptor comprising:(a) a main body having a first end and a second end and of a size and configuration adapted to be held within an end of one of the syringes at the juncture between the two syringes when the syringes are locked end to end directly to each other;(b) dividing means for dividing the main body such that there is (i) a first channel within the main body, the first channel extending from the first end of the main body to the second end of the main body, the first channel having a primary opening at the first end of the main body and a secondary opening at the second end of the main body; and (ii) a second channel within the main body, the second channel extending from the second end of the main body to the first end of the main body, the second channel having a primary opening at the second end of the main body and a secondary opening at the first end of the main body;(c) first valve means for selectively opening and closing the secondary opening of the first channel as the mixture is repeatedly transferred from one syringe to the other; and(d) second valve means for selectively closing and opening the secondary opening of the second channel in a manner opposite to that of the first valve means.
