  • 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: 20180036457
    Abstract: The invention described herein relates to a therapeutic, moisturizing coating composition for elastomeric articles which is applied directly onto the skin-contacting surface of the article as part of the manufacturing process. The coating composition is thermally stable and subsequently hydrates when contacted with a moisturized skin surface to convert into a liquid “lotion” form during wearing of the article. The coating composition provides therapeutic benefits to the wearer's skin as a result of wearing the article, such as improved skin moisturization, softness of feel, improved skin elasticity and firmness, and reduced redness and irritation. The invention is particularly useful in medical gloves, including examination and surgical gloves.

  • Publication number: 20170304511
    Abstract: Fluid collection systems and methods are disclosed which may utilize suction to draw fluids into containers for storage and eventual disposal. The system may utilize rigid or semi-rigid canisters to provide a chamber in which fluids may be collected under negative pressure, stored, and transported. The system may utilize disposable or reusable flexible, semi-rigid, or rigid liners for isolating fluid and liquid waste from the walls of the canister. In various embodiments, either a single canister assembly or multiple canister assemblies are mounted to a manifold, the manifold being configured to support each canister assembly and/or provide a connection to a source of suction for each canister assembly.

  • Patent number: 9770540
    Abstract: A collapsible liner for use in a canister of a medical fluid collection system is disclosed. The liner includes a flexible bag extending longitudinally between a top portion opposite a closed bottom portion, and at least one support element connected to the bag and disposed generally laterally relative to a length of the bag. When an interior of the bag is subjected to a vacuum, the at least one support element limits an extent of lateral collapse while permitting longitudinal collapse. The canister includes a second vacuum source port located remotely from the lid so as to subject a space between the collapsible liner and the canister to a second vacuum commensurate to the vacuum applied to the interior of the bag.

  • Publication number: 20160374416
    Abstract: Described are systems, devices, and methods for stripping a formed thin film elastomeric article such as a latex or synthetic polymer medical or surgical glove from a mold, inverting the article, and transferring and securing the inverted article to a mandrel for further on-line processing, integrating dip forming and off-line surface treatment processes into a single, continuous on-line process. The system can include a stripping apparatus including an actuation device for peeling the article from the mold and inverting the article, and a donning device to receive the inverted article. The system may position the article about a mandrel of the donning device. The mandrel may expand or separate to engage the interior of the inverted article to securely hold the article on the mandrel. The donning device may be coupled to a continuous loop conveyor chain to carry the donning device and the mounted article through on-line secondary processing.
