  • Patent number: 10335507
    Abstract: A fill assembly sterilization system for a blow/fill/seal machine utilizes a closed loop circulation of sterilant containing gas. A typical sterilant is nitrogen dioxide. The closed loop includes a shroud that defines a plenum and encloses the fill system. Optionally, at least one high efficiency particulate absorption (HEPA) filter is provided in the closed loop. Sterility assurance level of 10?6 can be achieved by subjecting the fill system to the sterilizing gas for at least 20 minutes at a temperature in the range of about 18° C. to about 30° C.

  • Patent number: 9101679
    Abstract: A method of sterilizing an article by sequentially exposing the article to hydrogen peroxide and ozone is disclosed. The article is exposed under vacuum first to an evaporated aqueous solution of hydrogen peroxide and subsequently to an ozone containing gas. The exposure is carried out without reducing the water vapor content of the sterilization atmosphere, the water vapor content being derived from the aqueous solvent of the hydrogen peroxide solution and from the decomposition of the hydrogen peroxide into water and oxygen. The complete sterilization process is carried out while the chamber remains sealed and without removal of any component of the sterilization atmosphere. For this purpose, the chamber is initially evacuated to a first vacuum pressure sufficient to cause evaporation of the aqueous hydrogen peroxide at the temperature of the chamber atmosphere. The chamber is then sealed for the remainder of the sterilization process and during all sterilant injection cycles.

  • Publication number: 20150139854
    Abstract: To improve throughput of biomedical waste treatment, the present inventors devised an exemplary ozone-based system including a shredder, a roll-off treatment bin with ozone injectors, an ozone source, and a controller. The controller monitors electric current drawn by the shredder as shredded waste enters the ozone-enriched treatment bin. In response to current falling below a predetermined low level, indicating that a batch of waste has been shredded and loaded into the treatment bin, the controller starts a treatment timer. The timer measures elapsed ozone treatment or exposure time. If additional waste is added to the shredder and a subsequent low-current condition is detected, the controller restarts the treatment timer. Expiration of the timer indicates that the waste in the roll-off bin is sterilized and ready for transport to landfills. The exemplary system provides continuous waste processing and promises to boost throughput by 50% over some conventional ozone-based waste-treatment systems.

  • Patent number: 8961874
    Abstract: According to the present invention a method for heat recovery in a device for the sterilization of biological material is provided. The present method eliminates the risk of contaminating the sterilized effluent with unsterilized biological material via the heat recovery system. In a device according to the invention, a heat recovery circuit is provided for transferring heat from the sterilized effluent stream to the biologically hazardous feed stream. Protection against contamination through leaks is obtained by maintaining at all times a pressure difference preventing biologically hazardous material from bypassing the heat treatment and flowing in the direction of the sterilized material.

  • Publication number: 20150044094
    Abstract: The present disclosure pertains to a ventilator treatment system configured to sterilize and/or disinfect a fluid pathway through a ventilator by providing a forced flow of treatment gas to the ventilator. Ventilators are frequently contaminated with bacteria and viruses during normal use. When a ventilator is moved from one patient to the next, there is a risk of contaminating the new patient with a pathogen from the previous patient. The application of treatment gas is especially practical for sanitizing hard to access surfaces such as those found in the cavities and conduits (the fluid pathway) of a ventilator. A treatment gas such as, for example, ozone, converts back to oxygen and has a short half life, which can be further reduced with humidity, heat, or inexpensive destruct catalysts.
