Dry disconnect cartridges and dual lumen needles for automated drug dispensers

摘要

Various aspects of the present disclosure relate to a dispenser system having a cartridge that includes a fluid path controllable by a valve of the cartridge. A pump component within the cartridge is operable to move fluid through the controllable fluid path. The cartridge includes a needle that extends from the cartridge body and is fluidly coupled to at least one of the controllable fluid pathways. The cartridge includes a vacuum bellows that surrounds the needle when the bellows is in the extended configuration. The vacuum bellows is compressible to expose the needle and also creates a vacuum condition in the bellows when the bellows is expanded from the compressed configuration to the expanded configuration. The needle can be a dual lumen plastic needle.
