Medicine reservoir and device for automatic dispensing of a liquid medicine

摘要

The reservoir has set of receptacles (2) for receiving a liquid medicine. A surface area i.e. non-circular area, of a displacement piston is surrounded by its outer circumference. A smallest extent of the surface area of the piston is effective for the displacement with the receptacles. The extent of the surface area of the piston for displacement is smaller than the diameter of a cylinder. A height of the cylinder corresponds to a design displacement path of the piston for the delivery of medicine. The cylinder has a volume corresponding to a design delivery volume of the reservoir. An independent claim is also included for a device for the automated release of a liquid machine comprising a medicine reservoir.
