摘要：
A medical injector is provided herein having a body a reservoir containing first and second mixable components, a stopper associated with the reservoir, a predetermined extent of advancement of the stopper causing mixing of the first and second mixable components a displaceable plunger disposed in the body a spring disposed to advance the plunger a first releasable retainer for releasably retaining the plunger in a first state against force of the spring a first trigger for causing the first releasable retainer to release the plunger a second releasable retainer for releasably retaining the plunger in a second state against force of the spring and, a second trigger for causing the second releasable retainer to release the plunger. The spring causes the plunger to advance from the first state to the second state. The plunger engages the stopper during the advancement from the first state to the second state so that the stopper traverses at least the predetermined extent of advancement thereby causing mixing of the first and second mixable components. Advantageously, with the subject invention, a medical injector is provided which allows for auto reconstitution with subsequent dose setting and auto plunger activation, the auto reconstitution and the auto plunger activations being activated by separate triggers.
