Abstract:
A limited flow rate drip chamber for an intravenous fluid delivery system, comprising:a housing comprising an inlet port having an inner diameter and an outlet port having an inner diameter, and at least one side wall defining a chamber between the inlet and outlet ports, the housing configured to channel intravenous fluid in a flow path from the inlet port through the chamber to the outlet port; anda member supported by the at least one side wall in the chamber between, and spaced from both, the inlet and outlet ports and positioned so that the intravenous fluid flowing into the chamber impinges against the member to reduce the velocity of the intravenous fluid and minimize formation of air bubbles in the intravenous fluid, the intravenous fluid impinging against the member flowing directly from the member to the outlet port,wherein the inner diameter of the inlet port is not less than the inner diameter of the outlet port, such that a flow rate of the intravenous fluid exiting the outlet port is not greater than a flow rate of the intravenous fluid entering the inlet port.
