International Classification:

A31M 37/00
C02F 1/44

US Classification:

604 601, 604 401, 604 501, 604 607, 604 615, 422 44, 210645, 210782

Abstract:

Methods and apparatus particularly involving the separation of blood into blood components and the collection of such components are disclosed. In one aspect, an extra-corporeal method for the collection of plasma and red blood cells is provided, wherein the collection of plasma and red blood cells may occur simultaneously or subsequently utilizing the same dual stage blood processing vessel. The flow of blood to the blood processing vessel and return of uncollected blood components may be provided via a single needle, wherein blood is removed from and returned to a donor/patient during alternating blood removal and blood return submodes. Platelet separation and collection options are also described. In either case, prior to red blood cell collection, a set-up phase may be carried out to set a predetermined hematocrit and AC ratio. Replacement fluid delivery may optionally also be provided either substantially continuously during any collection phase(s) and/or in a bolus mode.

Assignee:

Cobe Laboratories, Inc. - Lakewood CO

International Classification:

A61M 114
A61M 134

US Classification:

422 48

Abstract:

Filed:

Apr 26, 1982

Appl. No.:

6/371973

Inventors:

Roger J. Elgas - Littleton CO
Timothy M. Gordon - Morrison CO

Assignee:

Cobe Laboratories, Inc. - Lakewood CO

International Classification:

A61M 103

US Classification:

435 2

Abstract:

A membrane type blood oxygenator with a microporous membrane separating blood and air channels, the blood in the blood channels flowing downward to cause any accidentally introduced air bubbles to have an increased residence time in the membrane device owing to buoyancy, the blood being at a pressure sufficiently greater than the air pressure to cause passage of air bubbles through the pores of the microporous membrane to the air side prior to being carried out of the device by flowing blood.

International Classification:

A61M 3700

US Classification:

210745

Abstract:

An extracorporeal blood processing system is disclosed which includes a variety of novel components and which may be operated in accordance with a variety of novel methodologies. For instance, the system includes a graphical operator interface which directs the operator through various aspects of the apheresis procedure. Moreover, the system also includes a variety of features relating to loading a blood processing vessel into a blood processing channel and removing the same after completion of the procedure. Furthermore, the system also includes a variety of features relating to utilizing a blood priming of at least portions of the apheresis system in preparation for the procedure. In addition, the system includes a variety of features enhancing the performance of the apheresis system, including the interrelationship between the blood processing vessel and the blood processing vessel and the utilization of high packing factors for the procedure.
