A self-contained biological indicator includes an outer container that is translucent and liquid impermeable. The container is normally closed by a vapor-permeable, micro-organism-impermeable closure and contains a source of viable microorganisms, a culture medium, a composition that decomposes hydrogen peroxide, and a detector that undergoes a visible change in response to growth of the microorganisms. In operation, the indicator is first subjected to a sterilization cycle in a hydrogen peroxide sterilizer. Without opening the outer container, the microorganism source, culture medium, and hydrogen peroxide-decomposing composition are brought into contact. The indicator is placed in an incubator, after which the detector responds to any microorganism growth, indicative of incomplete sterilization. But for the hydrogen peroxide-decomposing composition, hydrogen peroxide that becomes bound to the microorganism support during sterilization, could kill the microorganisms afterwards, yielding a false indication of complete sterilization.

An apparatus and method for disinfecting a contact lens comprise a container having an inner surface and being sized to hold a contact lens to be disinfected and a liquid medium containing hydrogen peroxide; a substrate located in the container; and a metal component deposited from a vapor medium on the substrate. The metal component is present in an amount effective to promote the decomposition of hydrogen peroxide in the container.

Apparatus and method useful in disinfecting contact lenses

An apparatus for dispensing a liquid medium containing dissolved chlorine dioxide comprises a reservoir which defines a receptacle adapted for holding a precursor liquid medium having chlorine dioxide precursor dissolved therein and a tip assembly into which the precursor liquid medium passes after the precursor liquid exits the receptacle. The tip assembly comprises a chamber in which is located a promoter component effective to promote the generation of chlorine dioxide from the chlorine dioxide precursor in the liquid medium present in the chamber, an outlet providing a path for the liquid medium containing dissolved chlorine dioxide to exit the chamber, and an isolation assembly acting to effectively separate the precursor liquid medium in the reservoir from the promoter when it is desired that the precursor liquid medium from the reservoir be separated from the catalyst.

A squeezable dispenser having a main flexible outer container closed off by a top having an opening therein and an inner collapsible flexible fluid containing bladder. A one-way flow valve is mounted in the top normally closing off the opening in the top to prevent the contents of the bladder from contamination from external sources. A vent in the top provides fluid communication between the interior of the container and the exterior thereof. A sealing member overlies the valve and normally closes off the same. The dispenser can be squeezed to dispense liquid in the bladder out through the valve.

Valve controlled squeezable fluid dispenser

A squeezable dispenser having main flexible outer container closed off by a top and an inner collapsible flexible fluid containing bladder. A one-way flow valve is provided between the outer container and the inner bladder to prevent the contents of the bladder from contamination from external sources. A vent in the top provides fluid communication between the interior of the container and the exterior thereof. A sealing member overlies the vent and normally closes off the same when the dispenser is squeezed to dispense liquid in the bladder out through the valve.
