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.

Abstract: The device presented is designed to cause, in a mode of operation referred to as “normal” mode, a fluid to flow along this fluid path successively through the first cavity, the filter, the second cavity then the flow restrictor. The device is also designed to cause, in a mode of operation referred to as “purge” mode, a fluid to flow along this same fluid path through the filter but in the opposite direction to the normal flow of the fluid (in the normal mode of operation). Thanks to the “purge” mode, the fluid will detach impurities that have become trapped on the filter in order to clean same.

Abstract: The present disclosure relates to an indicator device which comprises one or several plungers inside an elongated cavity. Said indicator device, is intended to provide to the user at least one information related to the current status of a delivery system. The indicator device comprises at least one movable element configured to reach pre-determined positions in response to the status of the delivery system.
