PURPOSE:To almost simultaneously inject a medicine or the like in a patient at two related places by one injector for a liquid medicine by providing magnet type opening and closing valves to two outflow passages and opening one of the outflow passages while closing the other one of them. CONSTITUTION:When a current is supplied to one set of magnet coils A1, B2 of the valve opening and closing means 2 mounted to the protruding parts 1b, 1b of a pipeline main body 1 for a set time, one opening closing valve 6 opens an outflow passage 4 by the rapid upward movement of an iron piece 6a due to the magnet coil A1 and the other opening and closing valve 7 closes an outflow passage 5 by the rapid downward movement of an iron piece 7a due to the magnet coil B2 and, therefore, the liquid medicine in a pressed injector is injected in one affected region from the opened outflow passage 4 through a sheath. After the set time is elapsed, the supply of a current is changed over to the other set of magnet coils B1, A2 by an electric circuit and the liquid medicine is efficiently injected in the other related affected region from the outflow passage 5 through the sheath.
