Appl. No.:

8/697814

Inventors:

Robert R. McBride - Tustin CA

Assignee:

Baxter International Inc. - Deerfield IL

International Classification:

B01D 3700
B01D 3501

US Classification:

210506

Abstract:

A combined cardiotomy and venous blood reservoir according to a preferred embodiment of the invention provides a separate in-flow path for both cardiotomy fluid and for venous blood, and includes a cardiotomy fluid filter element also serving as an initial de-foamer. The cardiotomy fluid is de-foamed, filtered, and again de-foamed. The venous blood is de-foamed, and then both fluids are combined for flow from the reservoir. The filter area provided for cardiotomy fluid is advantageously separated from the area of a final de-foamer element. Thus, both the cardiotomy fluid and venous blood may flow through this final de-foamer element simultaneously along separate flow paths. The reservoir design provides greater freedom in selecting adequate filter area for the cardiotomy fluid, while allowing the selection of effective de-foamer element areas in order to achieve acceptable flow rates for both cardiotomy fluid and for venous blood under various conditions of operation for the reservoir. An advantageous ratio of filter and de-foamer element areas to the volume of the reservoir results, with the reservoir requiring only an essential volume of fluid for processing. Also, venous blood and cardiotomy fluid flow inlets to the apparatus may be rotatable in plan view independently both of one another and of a housing of the reservoir.

Abstract:

A breathing gas delivery system comprising a gas flow controller and at least one breathing apparatus. The gas flow controller has a body having an on/off switch, at least one gas input, and at least one gas output. The breathing apparatus comprises a T-shaped gas input having a body with two arms and a free end, a breathing bag coupled to the free end of the T-shaped gas input, a length of tubing having two opposed ends, wherein one end is coupled to the other arm of the T-shaped gas input, a filter coupled the length of tubing, and a nasal assembly coupled to the filter.

Abstract:

A breathing gas delivery system comprising a gas flow controller, at least one breathing apparatus, and at least one first length of tubing coupling the breathing apparatus to the gas flow controller. The gas flow controller has a body having an on/off switch, at least one gas input, at least one gas output, and at least one control mechanism for controlling flow of gas to the gas output. The breathing apparatus comprises a T-shaped gas input, a breathing bag coupled to the T-shaped gas input, a second length of tubing having two opposed ends, wherein one end is coupled to the other arm of the T-shaped gas input, a filter coupled the second length of tubing, and a nasal assembly coupled to the filter.
