Filed:

Aug 19, 1986

Appl. No.:

6/898048

Inventors:

George Jankowski - Media PA
Michael G. Maietta - Cogan Station PA
William E. Waters - Malvern PA

Assignee:

The West Company - Phoenixville PA

International Classification:

A61M 5245

US Classification:

604232

Abstract:

A holder for cartridges or containers for medicaments in injectable form comprising an elongated housing having a pocket for the cartridge, a head assembly including an elongated plunger rod adapted to be attached to the cartridge plunger for actuating the same to effect discharge of medicament from the cartridge and means operatively connecting the head assembly to one end of the housing for actuating a shank portion of the head assembly axially (longitudinally) in the housing. The head assembly and housing is made of dissimilar materials to facilitate relative rotation of the head assembly and housing and resist slippage when the shank exerts an axial force on the cartridge to seat it in the housing.

International Classification:

A45D 340

US Classification:

401264

Abstract:

Applicator assembly comprising a container for liquids having a bottom wall member, a cap member having means for detachably securing it over a discharge opening in the container. An upstanding wall and a bottom wall having an upstanding post member having an opening communicating with the interior of the container define a measuring chamber for a predetermined measured quantity of the liquid with a cylindrical wall portion of the cap member. An elongated tubular member is mounted in the opening in the post member extending downwardly into the container adjacent the lowest portion of the bottom wall member. A valve seat plate member is mounted at the open end of the cylindrical wall portion and has a wall portion terminating in a valve opening which is tapered towards the valve opening and functions as a funnel during discharge of contents to ensure complete transfer from the measuring chamber to a dispensing chamber above the measuring chamber. A flexible dauber having outlet holes is mounted over the outer end of the valve seat plate member and having a depending valve element biased solely by the dauber to normally seal the valve opening therein. The valve member is actuatable inwardly by pressure to overcome the bias of the dauber to permit flow of fluid from the measuring chamber to an enclosed dispensing chamber defined by dauber and valve seat plate member.

Appl. No.:

6/742286

Inventors:

William E. Waters - Malvern PA

Assignee:

Biosearch Medical Products, Inc. - Somerville NJ

International Classification:

A61M 2500

US Classification:

604165

Abstract:

An intubating device has a flexible tube with an open proximal end and a discharge opening adjacent its distal end. A hollow stylet connector plug is removably secured to the proximal end of the tube. A stylet is secured to the plug and extends through the interior of the tube to a point adjacent the distal end of the tube. The stylet has an outer diameter smaller than the inner diameter of the tube and smaller than the inner diameter of the plug to permit the passage of fluid between the stylet and the tube and between the stylet and the plug. A hollow connector fitting is integral with the plug and has a passage communicating with the interior of the plug. A stop accurately locates the stylet with respect to the tube preferably extending the tube.
