<p>A drip chamber (16) for an intravenous fluid delivery system includes a housing (24) having an inlet port (26) and an outlet port (28), the inlet and outlet ports each having an inner diameter, and the housing defining a chamber (30) between the inlet and outlet ports. The housing is configured to channel intravenous fluid in a flow path from the inlet port (26) through the chamber (30) and to the outlet port (28). A member (38) supported in the chamber (30) between the inlet and outlet ports (26,28) is positioned so that the intravenous fluid flowing through 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 inner diameter of the inlet port (26) is substantially equal to or greater than the inner diameter of the outlet port (28), such that a flow rate of the intravenous fluid exiting the outlet port is substantially equal to or less than a flow rate of the intravenous fluid entering the inlet port.</p> |
