Assignee:

Clintec Nutrition Company - Deer IL

International Classification:

B65B 328

US Classification:

141 1

Abstract:

A method for transferring fluids from multiple source containers to a single receiving container wherein fluid is transferred from a source container to a transfer chamber under the influence of a differential pressure and under the control of an occlusion force between the source container and the transfer chamber; the amount of fluid in the transfer chamber is confirmed; and, subsequently, the fluid is transferred from the transfer chamber to the receiving container under the influence of a differential pressure and under the control of an occlusion force between the transfer chamber and the receiving container.

Assignee:

Baxter International Inc. - Deerfield IL

International Classification:

B65B 328

US Classification:

141 83

Abstract:

A device is described for accurately transferring multiple individual fluids from multiple source containers into a single receiving container. Fluid flows from the multiple source containers through individual fluid conduits to a chamber having a single fluid outlet conduit. The fluid outlet conduit is in fluid communication with a single receiving container. A pressure conduit is in communication with the chamber for alternately creating positive and negative pressures in the chamber to cause fluid to flow from the individual source containers into the chamber, and to cause fluid flow from the chamber into the receiving container in response to commands from a controller.

Filed:

Nov 29, 1984

Appl. No.:

6/676130

Inventors:

Leon Huang - Hoffman Estates IL
John J. Selman - Vernon Hills IL

Assignee:

Baxter Travenol Laboratories, Inc. - Deerfield IL

International Classification:

G06F 1100

US Classification:

371 62

Abstract:

A self-checking timer usable with a host system includes a clock and a plurality of interconnected counters. During a power-up phase the timer generates a system reset signal and counts the counters in a predetermined sequence. A flip-flop is set and reset during the power-up phase and inhibits generation of the system reset signal. During a normal operating phase, the timer generates a test signal that must be responded to by the host system to continuously inhibit generation of the system reset signal.

Donald Warner - Gurnee IL

Assignee:

Baxter Travenol Laboratories, Inc. - Deerfield IL

International Classification:

B65B 328

US Classification:

141 1

Abstract:

A method and apparatus of collecting a desired end-point weight amount of material first conveys the material into the collection container until a predetermined weight amount is collected. The predetermined weight amount is less than the desired end-point weight amount by a selected initial weight offset amount. An additional incremental amount of material is next conveyed into the container for a predetermined fixed time period. In doing so, the method and apparatus gauge the particular flow characteristics of the associated flow system. A further additional incremental amount of material is conveyed into the collection container for another time period, the length of which reflects the anticipated flow characteristics of the system, based upon the performance of the system during the preceding period. The method and apparatus repeat this sequence until the then-existing weight amount equals or exceeds the desired end-point weight amount.

Assignee:

Spectrel Partners, L.L.C. - Phoenix AZ

International Classification:

G01F 100

US Classification:

364510

Abstract:

A testing apparatus for an intravenous pump houses a first component adapted to test at least one liquid flow characteristic of the pump and a second component adapted to be coupled electrically to the pump to test at least one electrical characteristic of the pump. An interior panel compartmentalizes the housing into two compartments isolated one from the other. The first component is confined solely within one of the compartments and the second component is confined solely within the other one of the compartments.
