International Classification:

A61L 2/20

US Classification:

422 33

Abstract:

A method of sterilizing an article includes placing the article into a chamber containing an inner atmosphere and exhausting the inner atmosphere to lower pressure in the chamber. Hydrogen peroxide vapor is present in the chamber during at least a portion of the step of exhausting the inner atmosphere. Exhaustion of the inner atmosphere is terminated and additional hydrogen peroxide is admitted into the chamber. Hydrogen peroxide vapor contacts the article for a sufficient period to effect sterilization of the article.

International Classification:

A61L002/20

US Classification:

422033000, 422027000

Abstract:

A method for cleaning and sterilizing a medical device comprises the steps of placing the device into a container, contacting the device with a cleaning solution, contacting the device with a liquid sterilant and lowering pressure in the container to vaporize the liquid sterilant in the container, thereby simultaneously completing sterilization of the device and drying the device. The washing and sterilization processes can proceed simultaneously.

International Classification:

A61L 2/24
A61L 2/20

US Classification:

422062000, 422292000

Abstract:

A sterilization system includes a sterilization chamber, a vacuum pump associated with the sterilization chamber, a vaporizer in association with the sterilization chamber, a sterilant distillation system associated with the chamber, a source of sterilant solution associated with the vaporizer and with the sterilant distillation system, and a control system which has programmed therein a first cycle in which the sterilant is admitted to the sterilization chamber at a first concentration, and a second cycle in which sterilant is concentrated in the sterilant distillation system to a second concentration, higher than the first concentration and from there admitted into the sterilization chamber and wherein the first and second cycles are selectable.

International Classification:

A61L 2/20

US Classification:

422033000, 422028000

Abstract:

A method, according to the present invention provides for sterilizing an interior of a lumen of an article. The method comprises the steps of: contacting the interior of the lumen with a liquid comprising hydrogen peroxide; heating the article; and exposing the article to sub-atmosphere pressure sufficient to vaporize the hydrogen peroxide within the lumen and for a time period sufficient to effect sterilization of the interior of the lumen. Preferably, the liquid comprises a condensed vapor.

Appl. No.:

7/625968

Inventors:

William H. Williams - Rancho Palos Verdes CA
Paul G. Jacobs - Northridge CA

International Classification:

A47L 534

US Classification:

15354

Abstract:

A scrubbing machine/vacuum cleaner which is carried by two spaced-apart front wheels and two spaced-apart rear wheels, having affixed to and extending from the front of the machine a cleaning head and brush assembly which is adapted to ride in proximity to, but in spaced-apart relationship from, the surface to be cleaned when all four wheels are resting on the surface to be cleaned. During actual cleaning operation, the head and brush assembly is adapted to press on the surface to be cleaned when the two rear wheels are raised from the surface to be cleaned. The front wheel assembly comprises a cross-member forming part of the frame carrying the machine, the cross-member having swivelably mounted thereto an axle. The axle carries the front wheels at its ends whereby the cleaning head is kept flat on the floor during the cleaning operation as the machine rolls over irregularities in the surface to be cleaned.

International Classification:

B29C 3508
B29C 4102

US Classification:

264 22

Abstract:

Apparatus and methods for stereolithographically forming a three-dimensional object includes a vessel for holding a building material and a smoothing member for forming a uniform coating over a previously formed layer of the object. The smoothing member has a plurality of blades. The smoothing member is swept over a previously formed layer of the object, in at least two directions. Different clearances between the lower surface of the smoothing member and the upper surface of the previously formed layer are used to provide a uniform coating for a subsequent layer over the previously formed layer. The sweeping velocity of the smoothing member can be varied. Retractable needles are attached to the smoothing member for adjusting a blade gap between the lower surface of the smoothing member and the surface of the building material.
