摘要:
A device for delivery of medicament, which device comprises an elongated housing; a container (4) mounted within said housing and adapted to contain liquid medicament; a stopper slidably arranged within said container; and actuating means comprising a resilient member (60), a driving means (50) having one end connected to the stopper and a second end being operably connected to the resilient member, retaining means (40) for releasably retaining said driving means in a first position where said resilient member has an accumulated energy, and activating means operably connected to said retaining means for releasing said driving means to a second position, upon actively operation by an user, such that said accumulated energy is transferred to the driving means for driving the stopper a predetermined distance within the container whereby the medicament within said container i delivered characterized in that the resilient member is a variable force spring adapted for generating a predetermined sequence of at least two different force profiles during the medicament delivery.
摘要:
The present invention relates to a delivery device for delivering predetermined amounts of fluid, comprising a body (10), a container (16) filled with fluid to be delivered arranged inside said body, said container comprising an opening for expelling said fluid and a wall (18) movable inside said container (16), a threaded plunger rod (46) arranged movable inside said body (10) in the longitudinal direction and in contact with said movable wall (18), a manually operated push means (14, 60) movable in the longitudinal direction capable of, upon operation, move said plunger rod (46) towards said movable wall (18), thereby expelling fluid, and means for transforming a generally linear movement of said push means (14, 60) to a rotational movement of said plunger rod (46).
