US Patent:

59119500, Jun 15, 1999

Filed:

Sep 30, 1997

Appl. No.:

8/941384

Inventors:

Xiaolan Chen - Irvine CA
Paul Taylor Jacobs - Trabaco Canyon CA
Szu-Min Lin - Laguna Hills CA
Robert M. Spencer - San Juan Capistrano CA
Harold R. Williams - San Clemente CA

Assignee:

Johnson & Johnson Medical, Inc. - Irvine CA

International Classification:

A61L 220

US Classification:

422 28

Abstract:

A system to deliver gas/vapor from solid materials. Specifically, the delivery system for the use of gas or vapor released from a solid material, such as a non-aqueous/solid hydrogen peroxide complex. The system is comprised of a delivery system that is configured to receive a plurality of disks containing the solid material and provide these disks into an injector. The injector heats the disks to produce a gas or vapor that is then provided into a chamber. The sterilization process can be done by gas or vapor alone, or in combination with plasma or ultra violet radiation. In particular, a control system automatically induces the delivery system to provide the injector with a disk and then remove the disk once the injection sequence is complete.

International Classification:

B65B 904
B65B 6118

US Classification:

53449

Abstract:

A cassette containing a group of sealed cells is used as a means for delivering doses of fluid to be injected into a sterilizing chamber. After the cassette is automatically positioned over a piercing mechanism, the cassette is moved downwardly so that a cell is pierced. Fluid is then forced out of the cell by pneumatic pressure into an injector valve, which opens in a manner which does not adversely affect a vacuum within the chamber.

US Classification:

422 23

Abstract:

A plasma-enhanced vacuum drying method is disclosed. It is advantageously applied in plasma sterilization processes in particular, and represents a significant improvement for general evacuation drying methods. Articles to be sterilized are placed in a sealed chamber and the chamber is evacuated. A plasma of residual gas species is generated in the chamber during an initial evacuation step. This promotes drying of the articles and advantageously allows a desired pressure to be attained more quickly than without the plasma. Sterilizing gas is injected into the chamber, and a second plasma is generated to activate the sterilizing gas plasma, thereby sterilizing the articles in the chamber.

Assignee:

Liquid Carbonic Corporation - Oak Brook IL

International Classification:

F25J 300
F26B 2106

US Classification:

62332

Abstract:

Hybrid cryo-mechanical apparatus is provided to collect condensable vapors from an incoming gas flow. The gas flow is refrigerated in a series of upstream mechanical refrigeration stages, and fed to an indirect contact heat exchanger suitable for operation with a cryogen refrigerant. Temperature of the cryogen leaving the heat exchanger is monitored, and is used to operate a control valve which throttles the heat exchanger output.
