Abstract
A delivery system configured to be secured on a patient skin which comprises a first container having a first variable volume; a second container having a second variable volume; and a skin adherable unit configured to secure the first container and the second container to the patient skin. The medical device may further comprise a containers' interface configured to operatively couple the first container and the second container such that a volume increase of the second variable volume may induce a volume decrease of the first variable volume. Preferentially, the system further comprises a vent device configured to prevent any unintended pressure increase in the first storage compartment.
