摘要：
The invention relates to a disposable injector comprising a housing, an injector-sided first cylinder-piston unit that can be at least temporarily filled and is arranged on the housing, and a container adapter which is detachably mounted upstream of the first cylinder-piston unit. Said container adapter supports an at least temporarily fillable second cylinder-piston unit. A solvent is disposed in the first cylinder-piston unit while a freeze-dried medicament is disposed in the second cylinder-piston unit. The solvent is conveyed to the medicament in the second cylinder-piston unit immediately before the disposable injector is used. A solution is formed in the second cylinder-piston unit. The solution is pumped into the first cylinder-piston unit in order to be able to administer said solution. Said disposable injector developed according to the invention allows a liquid and an active substance to be separately stored in a sterile manner while providing a space in which the active substance is dissolved in or mixed with the liquid in order to be applied.
