Claim:
An injector for liquid medicines comprising: a cylindrical body having an opening at each end thereof and provided with a fluid inlet and a fluid outlet forming side openings through opposite sides of the cylindrical body, axes of the side openings being substantially perpendicular to a longitudinal axis of the cylindrical body, said inlet and said outlet respectively communicating with a lumen of the cylindrical body, said inlet opening at a position closer to the distal end of the cylindrical body than where the fluid outlet opens; and first and second gaskets fluid-tightly and slidably arranged in the lumen of said cylindrical body and adapted to be moved along an inner wall of said cylindrical body, said first and second gaskets being spaced from one another to form a fluid chamber between them, said fluid chamber being filled with a liquid medicine; said first gasket being slidable from a first position where the fluid inlet and outlet are communicated with one another, to a distal end of the cylindrical body via a second position where said fluid chamber is prevented from fluid-communication with the fluid inlet but communicating with the fluid outlet to inject the liquid medicine in the fluid chamber through the fluid outlet.
