Patent abstract
A device for managing fluid is provided. The device includes: a drip chamber including: an inlet; and outlet; a check valve positioned between the inlet and the outlet, the check valve configured for managing fluid flowing between the inlet and the outlet; and an elastic element. The combination of the check valve and the elastic element limits the extent to which the one way valve may be opened by brief transient pressures appearing at the outlet of the drip chamber. This limiting effect improves the accuracy of fluid delivery in setups such as ‘piggyback’ or Secondary Mode infusions of two fluids using a single pump.
