Volumetric is fluid dispensing devices, systems, and methods |
摘要 |
A volumetric fluid dispensing device can include a fluid reservoir having at least one flexible wall and a dispensing reservoir oriented above the fluid reservoir. The dispensing reservoir can have an overflow return fluidly connected to the fluid reservoir such that the dispensing reservoir holds a measured volume of fluid. A reservoir conduit can be fluidly connected to the fluid reservoir and the dispensing reservoir to allow excess fluid to return from the overflow to the fluid reservoir. A dispensing conduit can also be fluidly connected to the dispensing reservoir to allow fluid to exit the dispensing reservoir. A mechanical wall actuator can be operatively associated with the walls for controllably flexing at least a portion of the walls sufficient to force fluid from the fluid reservoir to the dispensing reservoir via the reservoir conduit.
