US Patent:

42354129, Nov 25, 1980

Filed:

Oct 30, 1978

Appl. No.:

5/955810

Inventors:

Lucien M. Rath - Milwaukee WI
W. Martin Schultze - New Berlin WI

Assignee:

Plastronics, Inc. - Milwaukee WI

International Classification:

F16K 706

US Classification:

251 10

Abstract:

A clamping device for a fluid conduction tube comprises first, second, and third body members which are pivotally interconnected for movement between a generally flat, unfolded position and a folded together position in which the first and second body members generally face each other, and the third body member is generally perpendicularly disposed therebetween. The device may be slidably attached to the tube when the body members are in the unfolded position, and, when the device is in the folded together position, a portion of the tube is clamped between the first and second body members, thereby effectively blocking fluid conduction through the tube.

International Classification:

B29C 1902

US Classification:

156272

Abstract:

The apparatus is comprised of three basic parts, a mold member, an electrode pin member mounted inside the mold member and an electrode ring member mounted on the outside of the mold member. The mold member is made of an insulating, non-metallic material and is provided with a central cavity in which the pin member is mounted. The electrode pin member is made of a conductive metallic material and is provided with a cooling passageway system in the interior thereof. A pair of tubular members of plastic material are inserted into the open end of the mold cavity with their ends abutting each other in an area opposite the end portion of the pin member, with the electrode ring member positioned in the same general area. Radio frequency energy is transmitted between the electrode pin member and the electrode ring member and simultaneously therewith air under pressure is introduced into the passageway system inside the pin. The radio frequency energy will generate heat in the material of the plastic tube at the abutting ends thereof, causing the tubes to be welded together.

Abstract:

A front entry, flexible urinary collection bag with an inlet opening at a front wall thereof is connected with a fluid source through a rigid header attached to the flexible bag adjacent the inlet opening at the front of the bag and a fluid conductive connector held in coupling engagement by the header and having an elongate portion which makes fluid connection with the front of the bag through the inlet opening. The portion extends at an acute angle relative to the back of the bag when empty and makes connection with the front of the bag at a location laterally offset from the plane of symmetry, so that the back wall will not asymmetrically bulge away from the central plane of symmetry relative to the front of the bag. A front entry urinary collection bag adapted for automated urinary output monitoring is made by attaching a relatively rigid header to the top of the bag, attaching the inlet coupler to the front of the bag adjacent the top, inserting a male fluid conductive connector into mating relationship with a female connector carried by the header at the top of the bag and coupling a downwardly extending portion of the male connector to the inlet coupler.
