Drip chamber for intravenous fluid delivery system
First Claim
Patent Images
1. A drip chamber for an intravenous fluid delivery system, comprising:
- a housing comprising an inlet port and an outlet port, 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; and
a 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.

Abstract
A drip chamber for an intravenous fluid delivery system includes a housing having an inlet port and an outlet port, and 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 and to the outlet port. A member supported in the chamber between the inlet and outlet ports 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.

12. An intravenous fluid delivery system, comprising:
-
an intravenous fluid container; a drip chamber including a cylindrical housing comprising an upper inlet port at one end of the housing and in flow communication with the intravenous fluid container and a lower outlet port at an opposite end of the housing, the housing further comprising at least one side wall defining a chamber between the inlet and outlet ports, and configured to channel intravenous fluid in a flow path from the inlet port through the chamber to the outlet port, and a member supported by the at least one side wall in the chamber between, and spaced from both, the inlet and outlet ports and positioned in the flow path to disperse the intravenous fluid flowing from the inlet and thereby reduce the velocity of the intravenous fluid flowing toward the outlet port, the intravenous fluid impinging against the member flowing directly from the member to the outlet port; and means, in flow communication with the outlet port of the drip chamber, for delivering the intravenous fluid to a patient. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23)

24. A drip chamber for an intravenous fluid delivery system, comprising:
-
a housing comprising an inlet port and an outlet port, 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 trough the chamber to the outlet port; and a bar supported at least one end by the at least one side wall in the chamber and spaced from both the inlet and outlet ports 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.

25. A drip chamber for an intravenous fluid delivery system, comprising:
-
a housing having an inlet port and an outlet port, and 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; and a conically-shaped member supported in the chamber between the inlet and outlet ports and having an apex facing the inlet port, the member 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 member comprising slots extending radially from a position proximate the apex toward a periphery of the member to permit fluid to pass through the member after impingement.
