Publication number: 20150362109Abstract: A tube connection assembly having an elastomeric tube defining a fluid channel therethrough, and a retention sleeve, composed of a cross-linked PEX material having memory retention properties, disposed around the distal portion of tube device. Prior to partial assembly, the retention sleeve is expanded about 15% to about 50% from an unexpanded natural condition to an expanded condition, enabling placement onto the tube device. The tube distal portion and disposed retention sleeve can then be connected to a barbed male portion of a connector fitting, where the sleeve will radially retract back toward the natural condition, generating significant, radially uniform, hoop forces around the tube distal portion for fluid tight mounting to the connector fitting.Type: ApplicationFiled: June 12, 2014Publication date: December 17, 2015Inventor: Bradley H.

Patent number: 7655198Abstract: The connection, assembly, or fill of two or more pre-sterilized components having at least one terminal end each for attachment to another component, and an apparatus for performing such a connection, while maintaining the sterility of the components is disclosed. The resulting connection is made permanent by bonding the contacting components together using either a solvent bonding technique, a radio frequency sealer, a heat sealer, or any other suitable process. The connection is preferably made within an active sterile field. Using a low-voltage electron beam instrument, such as the MIN-EB™, a suitable sterile field sphere can be created. The terminal ends of the multiple components remain within the sterile field sphere until the possibility of contamination within the sealed components is significantly reduced to industry acceptable standards.Type: GrantFiled: December 30, 2005Date of Patent: February 2, 2010Assignee: Baxter International Inc.Inventors: Arnold C.
