Appl. No.:

10/609771

Inventors:

Todd Morrison - Dana Point CA, US

Assignee:

Ethicon, Inc. - Somerville NJ

International Classification:

A61L 2/24

G01N 33/18

US Classification:

422 3, 422 79, 435 31, 4352874, 436 62

Abstract:

A Biological Indicator Evaluator Resistometer (BIER vessel) provides enhancements in controlling the start and end points of exposure to a sterilant gas. The end point control employs a large volume relative to the test chamber volume upon which is drawn a deep vacuum and then exposed to the test chamber to quickly exhaust the sterilant gas from the test chamber.

Abstract:

A chemical vapor sterilization process is enhanced by flowing a portion of the sterilant vapor through an instrument container using a normal portion of the exhaust process. Preferably, an exhaust conduit which draws a vacuum on a sterilization chamber is oriented so that the container is adjacent an inlet to the conduit.

Appl. No.:

10/977961

Inventors:

Todd Morrison - Dana Point CA, US

Assignee:

Ethicon, Inc. - Somerville NJ

International Classification:

A61L 2/00

US Classification:

422292, 422 28

Abstract:

A cassette for a sterilizer has one or more cells containing a sterilant. Packaging for the cassette includes and outer fluid impermeable envelope and an absorbent web wrapped around the cassette to absorb and contain any sterilant which may leak out of the cassette. The absorbent web includes a superabsorbent polymer.

US Classification:

422 28, 422 29, 422292, 422295, 422298, 422305

Abstract:

A method of delivering a liquid sterilant to a sterilizer involves piercing a cell of a cassette with a first needle having a first lumen, flowing a gas into the cell to pressurize the cell relative to a pressure within the first lumen and drive the liquid sterilant out of the cell through the first lumen. The liquid sterilant travels from the lumen to a vaporizer in the sterilizer.

International Classification:

C12Q001/30

US Classification:

435/027000

Abstract:

A method for determining exposure of a test sample to hydrogen peroxide in an atmosphere includes placing a substrate into the atmosphere, contacting the substrate with the hydrogen peroxide, reacting the hydrogen peroxide with a dye intermediate to produce a chromophore indicative of the integrated exposure of hydrogen peroxide in the atmosphere; and correlating the chromophore to the integrated exposure of hydrogen peroxide in the atmosphere. The dye intermediate may be a dye-couple of 3-methyl-2-benzothiazolinone hydrazone hydrochloride (MBTH) and 3-dimethylaminobenzoic acid (DMAB). The intensity of the chromophore is indicative of an integrated hydrogen peroxide exposure.

US Classification:

422/033000, 422/117000, 422/292000, 422/300000

Abstract:

A door closure system for a vacuum sterilization chamber includes a mechanism to allow movement of the door with respect to the chamber at the latch and more preferably at the hinge. In one aspect the hinge attaches to the chamber via screws through elongated slots in the hinge. A spring biases the door toward the chamber. Forces applied by the hinge and by an opposite latch are normalized.

International Classification:

E05F003/20

US Classification:

016054000

Abstract:

A door closure system for a vacuum sterilization chamber includes a mechanism to allow movement of the door with respect to the chamber at the hinge. An elongated slot on the door captures a fixed shaft to allow rotation of the door. A spring in the door operates against the shaft biasing the door toward the chamber. Forces applied by the hinge and by an opposite latch are normalized.

Nick Nguyen - Silverado CA, US
Todd Morrison - Dana Point CA, US

International Classification:

A61L 2/16

US Classification:

422028000, 422300000

Abstract:

An occlusion minimizing connector connects a lumen in a lumen device to a source of sterilization fluid in an endoscope reprocessor. The connector has a sealing portion shaped to engage a surface on the lumen device. The sealing portion is formed of a resilient material biasing a sealing surface into contact with the surface on the lumen device. The biasing is such that the seal is maintained when pressure within the flow passage is below a predetermined level preventing leakage of the flow past the sealing portion. When pressure within the flow passage is above the predetermined level fluid leaks past the sealing portion to bathe the surface on the lumen device. Thus, the surface will not be occluded during a cleaning process.
