  • Publication number: 20090255033
    Abstract: The invention disclosed herein relates to improved elastomeric articles and processes for making the elastomeric articles. In particular, the invention relates to the surface modification of elastomeric articles such as industrial, surgical, and examination gloves that provides for improved consistency with respect to surface tack on a single article, between different articles from a single production batch, and between articles from separate production batches. The surface modification treatment comprises application of an aqueous mixture of silicone emulsion and ammonium salts of alkyl phosphates to the surfaces of elastomeric articles.

    Abstract: There is provided an improved sterilization wrap and a method for using the improved sterilization wrap to sterilize an article. The wrap is made of at least a first panel of sterilization material and includes an additional panel of material. The first panel is multi-layered and includes at least one pathogen filtration layer. The first panel is rectangular and has an outer periphery and a central portion. The outer periphery includes first, second, third and fourth edges. The additional panel of material is bonded to the first panel, approximately at a forty-five degree angle to the first panel, with a substantial portion of the additional panel being adjacent to the central portion of the first panel.

  • Patent number: 7594512
    Abstract: A fenestrated extremity surgical drape has improved seal integrity to reduce the occurrence of pathogenic contamination at the surgical site via migration through the seal. The seal has a non-linear configuration to eliminate uneven stress concentrations commonly located at the corners of rectilinear seals. An elastomeric apertured panel can be disposed between a film panel and a fiber/film laminate panel. These layers can be joined by a heat sealing operation along two spaced apart concentric seal locations ringing the aperture and a fenestration in the laminate panel. The assembly can then be affixed by adhering the underside(s) of one or more panels to a base drape, which has an opening aligned with the aperture and fenestration. A method of forming a fenestrated extremity surgical drape is also disclosed.

  • Publication number: 20090234064
    Abstract: An aqueous elastomer dispersion includes a dispersed phase and an aqueous phase. The dispersed phase includes an elastomer including curable aliphatic conjugated-diene elastomers, such as polyisoprene, and a minor amount of at least one additive. The aqueous phase includes water and other optional components in either a soluble state or a dispersion state. The aqueous elastomer dispersion may be prepared by dissolving an elastomer, such as rubber, and additives in a solvent mixture and then converting the resulting solution into an aqueous emulsion. The aqueous emulsion is concentrated and the solvent is stripped from it to yield a dilute latex. The dilute latex that is obtained is concentrated again. Articles made from the aqueous elastomer dispersion include medical gloves, condoms, probe covers, dental dams, finger cots, catheters and the like.

  • Patent number: 7578294
    Abstract: An nCPAP device including a generator body defining first and second fluid flow circuits each including a tube and first and second nozzles. The tube defines a passageway forming an axial centerline. The first and second nozzles are associated with the tube and each defines an inlet and an outlet. The inlets are open to a fluid supply, whereas the outlets are open to the passageway. Each nozzle is adapted to emit a fluid jetstream from the outlet along a flow direction axis. The nozzles are arranged such that the flow direction axes are non-parallel relative to each other and relative to the axial centerline. This configuration readily induces vortex shedding during an expiratory phase, thus facilitating jet fluid flow disruption and reducing a patient's work of breathing.

  • Patent number: 7566331
    Abstract: A reconfigurable surgical apparatus that includes a surgical instrument assembly that is formed with a hollow manipulation shaft. A linearly or rotationally movable prime mover is received within the shaft and is activated by an actuator located at a proximal end. A coupler is formed about a distal end of the shaft to have a capture ledge that is configured to releasably engage an interchangeable surgical tool that is formed with an anchor adapted to releasably mate to the capture ledge. The coupler may optionally incorporate a frangible portion that severs a portion of the coupler when the interchangeable surgical tool is removed from the apparatus to ensure single use operation of the tool.
