US Patent:

41404092, Feb 20, 1979

Filed:

Sep 2, 1977

Appl. No.:

5/830168

Inventors:

James H. DeVries - McHenry IL

Assignee:

Baxter Travenol Laboratories, Inc. - Deerfield IL

International Classification:

A47L 1317

US Classification:

401132

Abstract:

A disposable liquid applicator is provided in which the liquid to be dispensed is carried within a prescored container. Absorbent material is fastened to the container overlying the prescored portion. The container and the absorbent material cooperate to cause the liquid to be dispensed into the absorbent material when the container is bent away from the prescored portion and about itself.

Appl. No.:

6/100975

Inventors:

James H. DeVries - McHenry IL

Assignee:

Baxter Travenol Laboratories, Inc. - Deerfield IL

International Classification:

A61M 500

US Classification:

604 6

Abstract:

A prepackaged, self-contained fluid circuit module is selectively movable by an operator into and out of operative association with one or more pump rotors. The module includes a housing which supports two or more flexible conduits, which together define a prearranged fluid circuit. Portions of the flexible fluid conduits are outwardly disposed from the housing in upright, freestanding positions, even when the module is out of operative association with the pump rotors. The upright portions are purposely arranged relative to each other to facilitate only a particular operative relationship between the fluid circuit and the pump rotors when the module is subsequently moved into operative association therewith.

Inventors:

James H. DeVries - McHenry IL

Assignee:

Baxter Travenol Laboratories, Inc. - Deerfield IL

International Classification:

A61F 216

US Classification:

604 6

Abstract:

The monitor and fluid circuit assembly is used with a blood processing apparatus which is adapted for separating platelets from whole blood. The assembly is easily and simply attached to the apparatus and includes a holder, a plurality of flexible tubings held in and extending through the holder, monitor devices fixed within the holder and series coupled to various ones of the tubings and at least one tubing having a transparent wall section which is positioned adjacent an optical sensor of the apparatus. Several tubings extend in loops from the holder and are adapted for being received over and forming part of peristaltic pumps of the apparatus so that fluid can be pumped through the tubings. Other portions of some of the tubings extending from the holder are held in an umbilicus which is received through a rotatable holder in a centrifuge device of the apparatus. The plastic bag/receptacles are connected to the ends of these tubings and are adapted to be received in the centrifuge device for the centrifuging of fluids therein.

Abstract:

A fluid pumping assembly includes a prepackaged, self-contained fluid circuit module which is selectively movable by an operator into and out of operative association with one or more pump rotors of an associated apparatus. The module includes a housing which supports two or more flexible conduits, which together define a prearranged fluid circuit. Portions of the flexible fluid conduits are outwardly disposed from the housing in upright, freestanding positions, even when the module is out of operative association with the pump rotors. The upright portions are purposely arranged relative to each other to facilitate only a particular operative relationship between the fluid circuit and the pump rotors when the module is subsequently moved into operative association therewith.
