  • Patent number: 5851484
    Abstract: A system and method for handling contaminated operating room surgical instruments includes a rectangular porous strainer which is sufficiently large to fully contain a variety of surgical tools and instruments and a waterproof rectangular basin, sized to receive the strainer. The basin is adapted to fit stably onto a conventional surgical ring stand either alone, or with a separate adapter. The system replaces conventional round surgical basins which are not capable of safely containing the larger or longer surgical instruments typical of many modern surgical procedures. Utilizing the system eliminates the current practice of manually transferring contaminated instruments from the round surgical basins into larger soaking trays for transportation to the decontamination area.

  • Patent number: 5846457
    Abstract: The invention relates to a light-absorbing contact lens and process for preparing same. A contact lens is tinted with colorants which provide desired spectral transmittance characteristics over the tinted portion of the lens. The contact lens provides transmittance of incident radiation having a wavelength from 500 to 700 nm which is variable and wavelength-dependent. The lens of this invention also preferably filters out ultraviolet and blue light (wavelengths from 200 to about 500 nm). Various transmittance patterns for wavelengths from 500 to 700 nm are obtainable by appropriate choice of colorant combinations; the transmittance curve in this region and the colorants to achieve the desired transmittance characteristics are chosen to fill particular needs of a wearer as for example limiting transmittance of visible light in high intensity light environments.
