摘要：
An apparatus includes a housing and a medicament container disposed within the housing. The medicament container includes a first plunger and a second plunger, each disposed therein. The medicament container has a first configuration and a second configuration. In the first configuration, the first plunger is disposed in a first position and the second plunger is disposed in a second position spaced apart from the first position by a first distance. Accordingly, a first portion is defined between the first plunger and the second plunger. A second portion is defined between the second plunger and a distal end of the medicament container. In the second configuration, the first plunger remains in the first position and the second plunger is disposed in a third position spaced apart from the first position by a second distance, such that a volume of the second portion is greater when the medicament container is in the second configuration than when in the first configuration.
