  • Patent number: 10933151
    Abstract: A system and methods for sterilizing or disinfecting articles, particularly the hollow internal areas of medical instruments are disclosed. The system includes a plasma generator having an electrode, a shield, and a dielectric gap between the electrode and the shield. A source of electrical power is connected to the plasma generator for applying an electron energy density between the electrode and the shield. A source of gas comprising water vapor, oxygen and nitrogen provides a flow of gas between the electrode and the shield, to form a plasma containing acidic and/or oxidizing species. In the exemplary system, the temperature at the shield's surface is <150° C. when the electron energy density is >0.05 eV/molecule of the gas. Also disclosed is a method for disinfecting an article contaminated with a bio-film or spores, by exposing the contaminated article to the plasma for an exposure time sufficient to achieve at least 2-log10 reduction in colony forming units.

  • Publication number: 20200316239
    Abstract: A system and methods for sterilizing and drying contaminated articles, particularly medical articles, and more particularly the hollow internal areas of medical instruments or lumens of medical endoscopes. The system includes a plasma generator having an electrode, a shield, and a dielectric gap between the electrode and the shield. A source of electrical power connected to the plasma generator applies an electrode energy density between the electrode and the shield. A source of a sterilizing gas precursor provides a flow of the sterilizing gas precursor through the plasma generator to generate a plasma, thereby forming a sterilizing gas including acidic and/or oxidizing species. The contaminated article is exposed to the sterilizing gas for a time sufficient to achieve a desired degree of sterilization. A turbulent flow of a drying gas is used to dry the contaminated article alternately with the exposure of the contaminated article to the sterilizing gas.

  • Patent number: 10682830
    Abstract: Multilayered polymer films are configured so that successive constituent layer packets can be delaminated in continuous sheet form from the remaining film. The films are compatible with known coextrusion manufacturing techniques, and can be made without adhesive layers between layer packets that are tailored to be individually peelable from the remainder of the film. Instead, combinations of polymer compositions are used to allow non-adhesive polymer layers to be combined such that irreversible delamination of the film is likely to occur at interfaces between layer packets pairs. Some of the polymer layers, including at least one embedded layer, comprise an antimicrobial agent, and these layers may be positioned at the front of each layer packet. After the antimicrobial layer of one layer packet has been used, the packet can be peeled away to expose a pristine antimicrobial layer of the next layer packet. The antimicrobial agent may be organic.

  • Patent number: 10653823
    Abstract: A composite wound dressing apparatus promotes healing of a wound via the use of a micropump system. The micropump system includes a micropump that applies a subatmospheric pressure to the wound to effectively draw wound fluid or exudate away from the wound bed, or deliver fluids to the wound bed, without the need for a cumbersome external pressure (e.g. vacuum) source. Hence, the wound dressing and micropump system is portable which allows the patient mobility that is unavailable when an external vacuum source is used.
