摘要:
A dispensing device has a storage device and an air pump for dispensing a medical formulation. The storage device has multiple inserts, each insert containing a single dose of the formulation. Each insert is located in a separate and sealed cavity. The cavities can be individually opened for dispensing the respective dose from the respective insert by a pressurizing gas via a connecting element that is moveable relative to the inserts for individually supplying pressurized gas to a respective one of the receptacles. A mechanism is provided for preventing a back stroke of the connecting element during supplying of the pressurizing gas and dispensing of the formulation.
