Metered Dosing Method and Mechanisms Thereof

摘要

Enhanced metering systems for managing dosing aliquots feature cartridge housings for exchangeable cartridge with plugs for housing functional substances, extruding conduit tips with fluid flow conduits driven by advancing members for driving amounts of metered functional substance throughout the tips. Manual, pneumatic electrical and/or electronic means for advancing, combined with one way valves, viewing slots, multiple metering and dispensing ports enable two cartridge to be metered at once, as shown by graduated scales.

主权项

1. A device for dispensing a metered amount of a functional substance, the device comprising:
a cartridge housing having a proximal end, a distal end, and an internal bore, the cartridge housing configured to house an exchangeable cartridge including a cartridge plug and a functional substance; an extruding conduit tip at the proximal end of the cartridge housing, the tip comprising a fluid flow conduit; and an advancing member configured to fit into the internal bore and configured to move axially through the bore; and wherein, when the advancing member moves towards the proximal end of the housing, it forces a metered amount of the functional substance through the extruding conduit tip.
