US Patent:

45042004, Mar 12, 1985

Filed:

Dec 17, 1979

Appl. No.:

6/104407

Inventors:

Raymond G. Olson - Niles IL

Assignee:

Baxter Travenol Laboratories, Inc. - Deerfield IL

International Classification:

F04B 4312
F04B 4508

US Classification:

417476

Abstract:

A pressure pump for fluids in flexible tubing, which comprises a pressure member of generally circular periphery adapted for orbital motion about an axis of rotation. A sleeve member is positioned about the pressure member and defines channel means for receiving and retaining the flexible tubing in a predetermined position between the pressure member and sleeve member, and surrounding the pressure member. The sleeve member may be divided into a pair of substantially semi-circular jaws attached together at one end in hinged relation, to permit opening and closing of the jaws about the pressure member to facilitate installation of the tubing.

Appl. No.:

6/174489

Raymond G. Olson - Niles IL

Assignee:

Baxter Travenol Laboratories, Inc. - Deerfield IL

International Classification:

A61M 500

US Classification:

128214F

Abstract:

A liquid administration device comprises a flexible, collapsible bag for the liquid, an outlet tube communicating with the bag and a rigid housing enclosing the bag with the outlet tube projecting outwardly therefrom. Flexible, compressed cellular material is positioned within the housing, exerting pressure due to its compression on the bag which tends to urge the bag towards its collapsed position. Thus the liquid in the bag can be expelled through the outlet tube, with the flow governed by a valve, in a manner independent of gravity.

International Classification:

F04B 4312

US Classification:

417476

Abstract:

A pressure pump for fluids having a pressure member 12, 12a of generally circular periphery, means 14, 14a for moving the pressure member in an orbital motion about an axis of rotation, and a sleeve member 16, 16a made of a pair of hinged jaws 22, 22a positionable about the pressure member and spaced for receiving and retaining flexible tubing 18, 18a in an annular space between the pressure member and the sleeve member with the tubing surrounding the pressure member for pumping of fluids through the tubing. In accordance with this invention the jaws define end surfaces which abut together in the closed position having slots 34, 34a defined through the end surfaces communicating between the annular space and the outside to receive lengths of the flexible tubing occupying the annular space and extending into and out of the annular space through the slots.
