Medicament delivery device

摘要

A medicament delivery device for a reconstituted medicament, comprising a proximal housing part (12; 12″; 12′″), a distal housing part (10; 10″; 10′″), a medicament delivery drive unit and actuation means, wherein the medicament delivery drive unit is mounted in said distal housing part and wherein the actuation means further include an activation member (74; 101; 201) which is displaceable between an inactive position wherein the actuator is prevented from engaging the medicament delivery drive unit and an active position wherein the actuator is able to engage the medicament delivery drive, whereby the actuator is capable of interacting with said medicament delivery drive unit to perform a delivery of the reconstituted medicament only in the active position of the activation member and in the second position of the medicament delivery drive unit.

主权项

1. A medicament delivery device for obtaining and delivering a reconstituted medicament, comprising:
a proximal housing part configured to accommodate a multi-chamber container containing at least two agents; a distal housing part connected to the proximal housing part; a medicament delivery drive unit accommodated in the distal housing part, wherein the proximal housing part and the distal housing part are configured to be movable relative to each other from an extended position to a retracted position, whereby the medicament delivery drive unit acts on the multi-chamber container for mixing the at least two agents and thereby obtains the reconstituted medicament; and an actuation mechanism provided on the distal housing part and including an actuator provided to engage the medicament delivery drive unit when operated by a user for delivering the reconstituted medicament; wherein the medicament delivery drive unit is mounted in the distal housing part so as to be directly moved, by the proximal housing part when the proximal and distal housing parts are moved from the extended position to the retracted position, from a first position spaced from the actuator to a second position in which the medicament delivery drive unit can be engaged by the actuator; and the actuation mechanism further includes an activation member that is displaceable between an inactive position, in which the actuator is prevented from engaging the medicament delivery drive unit, and an active position, in which the actuator is able to engage the medicament delivery drive, whereby the actuator is capable of interacting with the medicament delivery drive unit to perform a delivery of the reconstituted medicament only in the active position of the activation member and in the second position of the medicament delivery drive unit.
