  • Publication number: 20150362109
    Abstract: 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.

  • Patent number: 8702129
    Abstract: A system for forming a fluid connection includes a first connector and a second connector. Both connectors include a tubular body having a membrane mounted on a distal end thereof. A support member facilitates the coupling of the connectors together so that the membranes are abutted together. Radiant energy is applied to the abutted membranes so as to first sterilize the membranes and then melt the membranes so that a passage is formed therethrough.

  • Patent number: 7655198
    Abstract: 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.

  • Patent number: 6996950
    Abstract: The invention relates to a method for sealing a peripheral attachment member onto a sealed pouch that has been previously filled with a product. The invention also relates to a pouch that includes a peripheral attachment member sealingly attached to at least one of its faces. The method includes a step of providing a multi-layer pouch that is configured so as to provide an inner sealant adapted to form a closed enclosure along sealing lines and an outer sealant that forms at least one external face of the pouch wherein the outer sealant has a melting point that is lower than the melting point of the inner sealant.
