Assignee:

Daniel Woodhead, Inc. - Northbrook IL

International Classification:

H02G 314

US Classification:

220242

US Patent:

54703271, Nov 28, 1995

Filed:

Sep 20, 1994

Appl. No.:

8/308870

Inventors:

R. Hayes Helgren - Mundelein IL
David E. Kramer - Northbrook IL

Assignee:

Abbott Laboratories - Abbott Park IL

International Classification:

A61M 3700

US Classification:

604411

Abstract:

The present invention relates to a pointed adapter which enables a blunt entry device such as a blunt cannula to readily penetrate an elastomeric closure such as a conventional vial stopper. The adapter also includes a collar which initially protects the adapter point from touch contamination and from accidental stick to the user.

Assignee:

Abbott Laboratories - Abbott Park IL

International Classification:

F04B 4304

US Classification:

417413

Abstract:

A solution pumping system including a disposable pump cassette is disclosed, with the system configured for efficient and accurate preparation of parenteral admisture solutions. The system includes a pump driver having a reciprocable pump plunger and a plurality of associated valve actuators. The disposable pump cassette of the system is configured for removable positioning in operative association with the pump driver, and includes a positive displacement pump configured for operation by the reciprocable pump plunger. The pump cassette further includes a plurality of liquid inlets, and at least one liquid outlet joined in fluid communication with the inlets. By selective operation of the valve actuators of the pump driver, one or more selected source solutions are drawn through the pump inlets by the positive displacement pump, and directed through the pump outlet to an admixture solution container. Preferred features of the present pump cassette facilitate liquid flushing to avoid mixture of incompatible source solutions, and enhance the sealing integrity of the cassette construction.

Appl. No.:

7/926239

Inventors:

David M. Kramer - Bartlett IL

Assignee:

Bartlett Tool and Manufacturing, Inc. - Bartlett IL

International Classification:

B65C 936

US Classification:

156353

Abstract:

A sealing apparatus for applying seals, such as valves, over a pressure relief passage of a container. Displaceable retention members, positioned next to a platen having an applicator surface, releasably secure one or more seals adjacent the applicator surface prior to attachment to the container. A seal attachment element moves the applicator surface toward and into a seal attachment position adjacent the container. As the applicator surface moves, the displaceable retention members release to, in turn, effectuate attachment of the seals over the pressure relief passage. A retraction element operatively attached to the platen causes return movement of the applicator surface and, in turn, return of the displaceable retention members back into a seal retaining position.

Appl. No.:

8/330284

Inventors:

Allen M. Elias - Mundelein IL
Warren P. Frederick - Wonder Lake IL
David E. Kramer - Northbrook IL

Assignee:

Abbott Laboratories - Abbott Park IL

International Classification:

A61M 3926

US Classification:

604167

Abstract:

A valve including a substantially rigid cannula and a valve member connected for operable communication with the cannula. The valve member is formed from a substantially resilient material and is movable with respect to the cannula between a first closed position and a second open position. The cannula cooperates to extend through the valve member during movement from the first closed position to the second open position to establish a fluid flow path through the cannula and the valve member. A sealing member is also provided which operates independent from a flow of fluid within the fluid flow path and independent from any component utilized with the valve to automatically provide positive sealing of an opening within the valve member when the valve member is positioned in the first closed position, the cannula extending through the opening during movement of the valve member.
