Abstract: A sterilization process challenge pack including a base tray, a first cover, and a second cover is configured to provide a restrictive flow path for gaseous sterilization medium to test the efficacy of a sterilization process. The base tray includes at least one chamber containing a biological indicator and/or chemical indicator. The first cover including a notch is configured to cover the at least one chamber. The second cover is attached to peripheral surfaces of the base tray except at an unsealed portion. A flow path through the unsealed portion and the notch in the first cover provides the only fluid communication between an external environment and the at least one chamber.

Abstract: A liquid sporulation method is described. A first liquid culture is prepared by adding bacterial cells to a sporulation broth, wherein an optical density (OD600) of the first liquid culture is in a range of 0.001 to 0.01. The first liquid culture is incubated and an optical density (OD600) thereof is increased to be in a range of 0.2 to 2.0. Second liquid culture is prepared by adding the incubated first liquid culture to a predetermined amount of additional sporulation broth, wherein an optical density (OD600) of the second liquid culture is in the range of 0.001 to 0.1, and a ratio of a volume of the second liquid culture to a volume of the first liquid culture is in a range of 10:1 to 150:1. The second liquid culture is incubated so an optical density (OD600) thereof is increased to be in a range of 1.0 to 4.0.

Abstract: A system for identification of abnormalities related to illumination of a target and automatic compensation therefor includes a lighthead and a controller. The lighthead is configured to illuminate the target. The lighthead includes a plurality of lighting modules configured to emit light therefrom. Each of the lighting modules includes a distance sensor configured to measure a distance from the lighting module to a surface toward which the lighting module is pointed. The controller is configured to identify one or more abnormalities of the measured distances, determine a true distance from the lighthead to the target based on the measured distances, predict an amount of illumination based on the true distance that would be supplied to the target without the identified abnormalities, and compensate for the identified abnormalities by respectively adjusting an amount of light emitted from the lighting modules to illuminate the target according to the predicted amount of illumination.

Abstract: A medical device support system including a central shaft, an extension arm, and a brake assembly. The extension arm has a support for a medical device and a hub at its proximal end mounted to the central shaft for pivotable movement about the central shaft. The brake assembly is secured in the hub for rotation therewith and includes first and second backing portions and first and second liners supported by the backing portions. At least the first liner is supported by the first backing portion by the first liner being snap-fitted to the first backing portion. The brake assembly includes an actuator configured to flex the first and second backing portions to urge the first and second liners toward and away from each other to respectively increase and decrease a frictional braking force to the central shaft.

Abstract: The present invention relates to phenol containing disinfectants that have superior broad-spectrum antimicrobial efficacy versus traditional chemistry such as quaternary ammonium-containing disinfectants or aliphatic alcohols. Hydrotropic surfactants are utilized in combination with generally environmentally friendly phenol containing compounds such as ortho-benzyl parachlorophenol (OBPCP), ortho phenylphenol (OPP), or parachloro-meta-cresol (PCMC) in the presence of suitable solvents such as an aliphatic alcohol and also in the presence of an inorganic acid, such as phosphoric acid. The solutions are free of para tertiary amylphenol (PTAP), have a low pH and are very stable with respect to gamma irradiation. They can be used with respect to hard surface disinfection, and also as a tuberculocide, a fungicide, a bactericide, and a virucide.

Abstract: A process for determining the viability of a biological indicator includes exposing the biological indicator to a viability detection medium, the biological indicator including test microorganisms, the exposing the biological indicator to the viability detection medium producing a gaseous reaction product when one or more of the test microorganisms are viable. The presence or absence of the gaseous reaction product produced by the biological indicator combined with the viability detection medium is detected with a sensing device, the sensing device comprising an electro-mechanical sensor, wherein the presence of the gaseous reaction product indicates the presence of viable test microorganisms and the absence of the gaseous reaction product indicates the absence of viable test microorganisms. A sterilization detection device includes a container configured to contain the biological indicator, a viability detection medium, and the sensing device.
