  • Patent number: 8079365
    Abstract: A surgical drape has a fenestration configured to aid in identifying an anatomical point of interest and positioning the fenestration at the surgical site. In one preferred form, the surgical drape has a chevron-shaped fenestration for positioning the fenestration relative to the xiphoid process region of a patient, which is useful for establishing the sterile field in certain bariatric procedures. An anesthesia screen at a head of the drape extends laterally to the sides of the base sheet forming the fenestration and defines integral arm board covers. The lateral ends of the anesthesia sheet are sealed in part to close the ends of the arm board covers. A secondary base sheet defining a smaller, secondary fenestration is releasably attached to the base sheet so that the fenestrations can be aligned with one another. Various instrument and chord management features are also included. A method of making the drape is also disclosed.

  • Publication number: 20110271955
    Abstract: A surgical mask provides a wide range of wearers with a good fit and improved comfort, facilitates proper use of the mask, and reduces or eliminates fogging of eyewear, as compared with typical masks. The mask may include a pair of ties that are joined to the upper, central, and lower parts of either side of the body of the mask with the assistance of restraint members. The mask may also include a sealing member that reduces or eliminates gaps between the wearer's face and the upper part of the mask by forming a seal between the wearer's face and the mask in use. In addition, the mask may include a barrier panel that reduces or prevents the wearer's breath from escaping through the mask and rising to the wearer's eyewear.

  • Publication number: 20110203227
    Abstract: The present invention relates generally to methods of sterilizing elastomeric articles in a manner that prevents and/or reduces degradation to the articles, particularly degradation that may be caused and/or accelerated by sterilization techniques such as gamma irradiation, x-ray irradiation, and electron-beam processing. The methods include packaging the elastomeric articles in order to improve their resistance to degradation. In certain aspects of the invention, packaged elastomeric articles, optionally containing one or more antidegradants, such as antioxidant and/or antiozonant compounds, are also provided. The methods of providing degradation-resistant elastomeric articles in accordance with the present invention may also be used to reduce the occurrence of cracking and discoloration in elastomeric articles, regardless of whether they are subjected to sterilization.

  • Publication number: 20110203596
    Abstract: The invention disclosed herein relates to an improved process for making elastomeric polyisoprene articles. In particular, the process of the invention is a system which produces synthetic polyisoprene articles exhibiting tensile strength properties similar to that of solvent-based processes using natural rubber latex. The process comprises an accelerator composition at the pre-cure stage comprising a dithiocarbamate, a thiazole and a guanidine compound. In a preferred embodiment, the accelerator composition comprises zinc diethyldithiocarbamate (ZDEC), zinc 2-mercaptobenzothiazole (ZMBT) and diphenyl guanidine (DPG), in conjunction with a stabilizer, such as sodium caseinate. The invention also includes an elastomeric polyisoprene product made by the process, such as a surgeon's glove.

  • Patent number: 7997277
    Abstract: A method of forming a fenestrated extremity surgical drape includes providing 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.

  • Publication number: 20110178234
    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.
