Filed:

Oct 25, 1994

Appl. No.:

8/328996

Inventors:

Robert W. Pierce - Wrentham MA
Neil Jolly - Brighton MA
Richard V. Kennedy - Hyannis MA

Assignee:

Becton, Dickinson and Company - Franklin Lakes NJ

International Classification:

A61B 1732

US Classification:

606167

Abstract:

This invention relates to an improved guarded surgical scalpel having a movable guard that can be retracted to expose the blade and that can be extended to cover the sharp cutting edge of the blade. The guard is telescopically mounted inside the blade handle and includes a deflectable top wall portion that holds a detent pin. This detent pin engages a slot having upturned ends that is formed in at least one side wall of the blade handle. The detent pin is biased upwardly into the upturned ends to hold the guard in the retracted or extended position.

Appl. No.:

6/928058

Inventors:

Richard B. Kennedy - Ridgefield CT

International Classification:

B01F 900

US Classification:

366279

Abstract:

A mixing device and method wherein liquids are rotatingly mixed in a disposable plastic bag mounted in and outer receptacle. The bag is provided with extending portions which overlap the open top of the outer receptacle. The interior sidewalls of the outer receptacle are inwardly sloping defining a truncated conical interior. When the bag is filled with liquid to be mixed the bag conforms to the sidewalls and does not twist around a rotating mixing element disposed through the open tops of the bag and outer receptable for mixing the contents of the bag. The mixing element is centered in the bag by a cap-like cylindrical structure that engages the top of the outer receptacle.

C08J 900

US Classification:

366130

Abstract:

An improved mixing device for mixing at least two of a plurality of pressurized liquids, the device consisting of hollow tubular member defined as having a longitudinal axis, one or two open ends and an interior wall member, one of the open ends having at least two cut-out portions generally symmetrically disposed about the axis, a segmental slot member generally radially disposed in the hollow tubular member between each of the cut-out portions for receiving a supporting projection in locking engagement therewith, and an envelope mounted on and extending about each of the cut-out portions for receiving and encompassing a conduit member terminating at and within each of the cut-out portions, each envelope being disposed, constructed and arranged for directing one of the plurality of pressurized liquids onto a proximate area of the interior wall means thereof. The wall is cleaned by turning off the fluid flow but the blades continue to be rotationally driven whereby the wall is wiped clean by the blades which push the residue out the tubular members.
