Abstract
Prefilled syringe for injection of two liquids includes a syringe body 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 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 a plunger, the first and second gaskets are forced to move forward so that two medical solutions are injected one after another.
