  • Patent number: 10821197
    Abstract: A container includes a first wall and an opposing second wall that extend between a first end and an opposing second end, a first fluid flow path being bounded between the first wall and the second wall. An inlet is formed at the first end and communicates with the first fluid flow path. An outlet is formed at the second end and communicates with the first fluid flow path. The first wall includes a primary wall portion having a first opening extending therethrough in alignment with the first fluid flow path. A secondary wall portion extends over the first opening and is secured to the primary wall portion so as to seal the first opening closed, the secondary wall portion being comprised of a film having a thickness that is less than a thickness of the primary wall portion.

  • Patent number: 9239405
    Abstract: A particle detection system is provided, including a sensing chamber having an inlet nozzle, an outlet nozzle, and an interrogation zone defined therebetween. Particles in a sampled environmental gas are prevented from escaping the interrogation zone by pressurizing the sensing chamber such that the pressure therein is higher than that in the outlet nozzle. This is accomplished by providing a source of extra gas to the sensing chamber, for example, by diverting gas from an inlet flow path directly to the sensing chamber.

  • 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.
