Patent number: 8888143Abstract: Fluidic coupling assemblies include a fitting body having a single integral piece or separable pieces such as male and female fittings such as luer fittings. The assemblies further comprise a rotatable fastening assembly having a drive collar and a driven member, and at least one resilient member having a spring bias that defines a threshold torque of the rotatable fastening assembly. The spring bias may be directed axially or radially with respect to the longitudinal axis of the fluidic coupling assembly. The resilient member is configured to prevent overtightening of the fluidic coupling assembly by allowing the drive collar to rotate the driven member only when less than a threshold torque is applied. Rotation of the rotatable fastening assembly imparts a compressive force on the resilient member, and the resilient member yields when the compressive force exceeds the spring bias of the resilient member.Type: GrantFiled: September 24, 2012Date of Patent: November 18, 2014Assignee: Diba Industries, Inc.Inventors: Stephen C. Fog, Gary C. Helstern

Publication number: 20140102561Abstract: Quick-release connectors and connection assemblies comprising the quick-release connectors include an inlet coupling and an outlet coupling. A compressible check valve in the inlet coupling may be formed from a resilient elastomeric material. A plunger body in the outlet-coupling proximal portion may include a plunger neck portion, a plunger channel, and a plunger inlet. An outlet valve in the outlet coupling may prevent reverse fluid flow in the outlet coupling. In a disconnected state of the connector, a check valve contact surface of the compressible check valve seals against a sealing member to prevent fluid flow thorough the inlet coupling. In a connected state of the connector, the plunger neck portion protrudes through the sealing member and compresses the compressible check valve to place the plunger inlet in fluidic communication with a valve clearance opened between the check valve contact surface and the sealing member.Type: ApplicationFiled: October 10, 2013Publication date: April 17, 2014Applicant: DIBA INDUSTRIES, INC.Inventor: Paul J.

Patent number: 5494420Abstract: A self-aligning connection between a rotary and reciprocating pump piston allows relative radial movement between the pump piston and the rotary cam. The self-aligning connection is formed by a pin carried by the rotary cam and is positioned in a radial recess located in the pump piston. An improved drive for the rotary cam is perfected by a cam follower pin supported from the housing by a roller bearing race which is pressed fitted within a bore formed by the pump housing. The pump piston abuts a TEFLON pad located in the pump cylinder to reduce dead space and insure that the pump produces accurate volumes. The employment of different plastic materials between the rotary cam and the pump housing provides an improved bearing surface.Type: GrantFiled: May 31, 1994Date of Patent: February 27, 1996Assignee: Diba Industries, Inc.Inventors: James A.
