  • Patent number: 12214108
    Abstract: A water-based hydrogel polymer coating and a method of application to natural rubber or other elastomeric latex products are provided. The water-based hydrogel polymer is mixed with a blend of at least one elastomeric material to provide a hydrogel polymer blend composition. The water-based hydrogel polymer blend composition is applied in a single application to an elastomeric article, such as gloves, without additional solvents in the polymer blend composition and without a separate acid or chemical priming step. The water-based hydrogel coating herein provides increased lubricity to facilitate improved wet and dry donning of the elastomeric article.

  • Patent number: 10421569
    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: 20180110579
    Abstract: An integrated tray and wrap system for supplying components used in medical procedures is provided and a method of manufacturing the tray while filling and sealing in one continuous process. The trays can be formed on a process line, such as by a thermo-form-fill-seal technique, and once the cavity of the tray is formed, the desired medical components can be loaded into the tray cavity as the formed trays are advanced down the process line. After the components are loaded, a pre-folded drape or non-woven sheet can be affixed to an inner ledge of the tray along an inner fenestration of the drape or sheet, thus attaching the drape or sheet to the tray. Once the drape has been attached, the tray continues to advance along the process line to receive a cover film that can be heat-sealed to the outer rim of the tray.

  • Publication number: 20180056056
    Abstract: Aspects of the present disclosure include a connector that is suitable for connecting medical suction tubing with at least two different types of fluid ports of a medical fluid collection system. In certain aspects, the connector includes a generally cylindrical body portion having a cylindrical outer surface extending generally parallel to a central longitudinal axis of the body portion, and an inner surface defining a primary conduit extending through the connector. At least one lateral closure wall extends radially outward from the outer surface of the body portion. At least one annular skirt wall extends longitudinally from the at least one lateral closure wall, including a first annular skirt wall that serves to receive an open mouth of a first fluid port having a relatively small diameter, and a second annular skirt wall that serves to receive an open mouth of a second fluid port having a relatively larger diameter.

  • Publication number: 20170105807
    Abstract: A surgical drape having an attachable fluid control pouch and geometric alignment feature are described. The surgical drape may be fenestrated and include a base drape panel, an absorbent intermediate panel, and a mounting panel. The mounting panel may have a fluid impervious top surface that forms a higher quality adhesive seal with the adhesive attachment areas of the fluid control pouch. The surgical drape panels may be joined together by a continuous fluid impervious seal surrounding the fenestration. The fluid control pouch attachment edge may include a geometric structure that aligns with a corresponding geometric structure of the fenestration such that the fluid control pouch can be effectively positioned regardless of its rotational orientation relative to the surgical drape.

  • Patent number: 9604778
    Abstract: Various implementations of a fluid collection system having a flexible liner are disclosed. In one exemplary variation, the fluid collection system may include a container having a top opening, a lid configured to close the top opening, and a flexible liner attached to the lid. The liner may be interposed between the lid and the container when the lid closes the top opening. The liner and the lid may define a substantially sealed interior space therebetween. The lid may include an access port through which the interior space receives fluid. The flexible liner may also be configured to controllably collapse as the fluid is removed from the interior space.
