摘要：
A medication delivery device (1) comprising: or a housing (3) having a proximal end and a distal end, or a medication receptacle (2) designed to connect with the housing (3) or a piston rod (17) which can move in a distal direction to deliver medication and or an actuator device to rotate the piston rod in a first rotational direction and, thus, move the piston rod (17) in the distal direction to deliver medication ； characterized in that the piston rod comprises two threaded sections (15, 16), a first threaded section (15) being provided for threaded connection with a reset element (11) and a second threaded section (16) being provided for threaded connection with the actuator device and in which the threads in the first and second threaded sections (15, 16) are arranged in opposite directions, in which - in an operative state, a readjustment element (11) is prevented from rotating with respect to the housing (3), thus preventing the piston rod (17) from moving in a proximal direction, and - in a readjustment state the readjustment element (11) is allowed to rotate with respect to the housing (3), the medication supply device can be readjusted by rotating the piston rod (17) and the readjustment element (11) in a second rotational direction and moving the piston rod (17) in the proximal direction.Un dispositivo de suministro de medicación (1) que comprende: o una carcasa (3) que tiene un extremo proximal y un extremo distal, o un receptáculo de medicación (2) diseñado para conectarse con la carcasa (3) o un vástago del pistón (17) que puede moverse en una dirección distal para suministrar medicación y o un dispositivo accionador para hacer girar el vástago del pistón en una primera dirección rotacional y, de esta manera, mover el vástago del pistón (17) en la dirección distal para suministrar medicación； caracterizado por que el vástago del pistón comprende dos secciones roscadas (15, 16), proporcionándose una primera sección roscada (15) para conexión roscada con
