Abstract
A filling member (43) in a medicament delivery device (1), the filling member (43) includes a first conduit (12) that fluidly communicates with a reservoir (4) and a second conduit (14) that fluidly communicates with a pump (3) and with the first conduit (12), wherein the filling member (43) provides two-way medicament flow that enters the reservoir (4) via the first conduit (12), exits the reservoir (4) into the first conduit (12) and the second conduit (14), and exits the second conduit (14) to the pump (3). The reservoir (4) includes a reservoir tube (44A) having one end that is formed with the reservoir (4), and the reservoir tube (44A) having another end that is press fit to the filling member (43) to establish fluid communication with the reservoir (4).
