  • Patent number: 8283133
    Abstract: The disclosed technology relates to a sterilization indicator, including a carrier, the carrier having a first surface and a second surface; a support, the support having a first section and a second section, the carrier overlying the first section of the support, the second surface of the carrier being adhered to the first section of the support; and a biological indicator supported by the carrier; the sterilization indicator being formed by applying the biological indicator to the carrier and then adhering the carrier to the support, the carrier being adhered to the support using sonic welding, in which the sonic welding, when applied to the carrier with the biological indicator applied, exhibits no significant difference in viability of the biological indicator following the sonic welding as compared to prior to the sonic welding.

  • Publication number: 20120194092
    Abstract: Methods and apparatuses for starting a discharge lamp are disclosed. In some embodiments, a lamp has an outer envelope connected at one end to a base and enclosing multiple double-ended arc tubes. Each arc tube is electrically connected at one end to an electrical lead positioned proximate the base of the lamp and at the other end to an electrical lead positioned proximate the distal end of the envelope. A voltage pulse is applied to the electrical lead positioned proximate the distal end of the envelope. Random starting of the arc tubes may thus be effected so that each arc tube is about equally likely to start, promoting uniformity of arc tube usage and long lamp life. Multiple arc tubes may be bulbous and staggered in axial displacement for space efficiency, and a diffusing shroud may improve optical characteristics. A heat barrier may facilitate fast restrikes.

  • Patent number: 8173389
    Abstract: The disclosed technology relates to a sterilization indicator and a process to concentrate signal generated by constraining it to a minimal surface, in a minimal volume and minimal pH and growth buffering or mediating influences. The sterilization indicator may comprise a carrier 12, the carrier having a first surface 14 and a second surface 16; a support 20, the support having a first section 22 and a second section 24, the carrier 12 overlying the first section 12 of the support 20, the second surface 16 of the carrier being adhered to the first section 22 of the support 20; and a biological indicator 30 supported by the carrier 12. The second section 24 of the support 20 may be of sufficient dimension to permit handling the sterilization indicator 10 without contacting the biological indicator 30. A process for making the sterilization indicator is disclosed. Processes for using the sterilization indicator are disclosed.

  • Patent number: 8084247
    Abstract: A biological indicator for monitoring the effectiveness of a sterilizing or disinfecting treatment or process. A compound or condition is disclosed which comprises a substrate having a surface layer containing functional groups thereon desirably free of silicon linking groups. The functional groups are desirably in the form of a monolayer of a uniformed distribution and of a selected quantity. Various types of microorganism indicators, such as spores, and/or etiological agent indicators are covalently bonded to the surface layer functional groups through a crosslinking reagent and thus form a uniform number and distribution of the microorganism and/or etiological agent indicators. After being subjected to sterilization or other similar disinfecting treatments or processes, along with various articles such as instruments, the indicator can be cultivated to determine the effectiveness of the sterilization, disinfection, etc. treatment or process.

  • Patent number: 8039251
    Abstract: A biological indicator for monitoring the effectiveness of a sterilization or disinfection treatment or process. The biological indicator comprises a substrate having a surface layer containing functional groups thereon desirably free of silicon linking groups. The functional groups are added to the surface through the use of a functionalized silane coupling agent, wherein two different functional groups are generally utilized and the functionalized silane is applied in a uniform and consistent manner thereby assuring that the microorganism or etiological agent indicators are attached to the substrate in a uniform and consistent manner through non-covalent bonding to the functional groups. After being subjected to sterilization or other similar disinfecting treatments or processes along with various articles such as instruments, the indicator can be cultivated or cultured to determine the effectiveness of the sterilization or disinfection treatment or process.

  • Patent number: 7960169
    Abstract: A biological indicator for monitoring the effectiveness of a sterilizing, disinfecting treatment or process. A compound or condition is disclosed which comprises a substrate containing functional groups residing on a surface thereof, said functional end groups being desirably free of silicon linking groups. The functional end groups are desirably in the form of a monolayer of a uniform distribution and of a selected quantity. Various types of microorganisms, such as spores, fungi, mycobacteria, vegetative bacteria, protozoa, and/or etiological agents are covalently bonded to the functional end groups through a zero-length crosslinking agent and thus form a uniform number and distribution of microorganisms and/or etiological agent indicators on a surface of the substrate.
