USPTO Abstract
Prefilled syringe for injection of two liquids includes a syringe body (1) with an injection port at a closed end thereof, first and second gaskets fluid-tightly fitted into the syringe body to separate two medical solutions filled therein, and a closing member (5) for closing the injection port. The syringe body is provided with bypassing grooves extending in the longitudinal direction of the syringe from a position adjacent to the closed end thereof. Liquid communication means is provided between the closed end and the first gasket. By pushing plunger (2), the first and second gaskets are forced to move forward so that two medical solutions are injected one after another.
