US Patent:

6637124, Oct 28, 2003

Filed:

Jan 16, 2001

Appl. No.:

09/761081

Inventors:

Jeffrey C. Pederson - Minneapolis MN

Assignee:

3M Innovative Properties Company - St. Paul MN

International Classification:

G01B 310

US Classification:

33758, 33494

Abstract:

An adhesive backed measuring tape is disclosed that can provide customized, printed measurement scales on a single flexible backing that has a positionable or repositionable adhesive for contact with flat surfaces, single curved surfaces, or compound curved surfaces. In a preferred embodiment, the measuring tape has multiple scales printed thereon. The combination of linear sections and transverse axes defined by intervals can permit a variety of repeating scales on a single tape, minimizing waste of tape unrolled from a dispenser.

International Classification:

C12M 1/34
C12M 1/40

US Classification:

4352887

Abstract:

A biological sterilization indicator (BI) and a method of using same for assaying the lethality of a sterilization process. The BI can include a housing, which can include a first portion, and a second portion, which can be movable with respect to the first portion between a first and second position. The BI can further include a frangible container comprising a liquid. The BI can further include a spore reservoir and a projection positioned in the housing. The projection can be configured to fracture the container when the second portion of the housing is moved from the first position to the second position. The method can include maintaining a minimal cross-sectional area of space around the container when the second portion of the housing is in the first position, and fracturing the container in response to moving the second portion between the first and second positions.

International Classification:

C12Q 1/02

US Classification:

435 34, 4352887

Abstract:

A biological sterilization indicator (BI) system and method. The system can include a BI and a reading apparatus comprising a well. The BI can include a housing, which can include a first portion, and a second portion movable between a first “unactivated” position and a second “activated” position. The BI can further include a frangible container containing a liquid and dimensioned to be positioned in the housing. The reading apparatus can be configured to detect activation of the biological sterilization indicator, for example, by detecting that the second portion is in the second position, and/or by detecting that the liquid from the frangible container is present in a specific chamber of the biological sterilization indicator. The method can include positioning the BI in the well of the reading apparatus and detecting activation, for example, by detecting one or more of the above conditions.

US Classification:

4352874

Abstract:

A biological sterilization indicator (BI) system and method. The system can include a BI and a reading apparatus comprising a well. The BI can include a housing, which can include a first portion, and a second portion movable between a first “unactivated” position and a second “activated” position. The reading apparatus can detect at least one of (i) when the well is empty; (ii) when the biological sterilization indicator is positioned in the well with the second portion of the housing in the first position, and (iii) when the biological sterilization indicator is positioned in the well with the second portion of the housing in the second position. The method can include detecting at least one of the above conditions, which can be used to detect an activation status of the biological sterilization indicator.

International Classification:

C12Q 1/22

US Classification:

435 31, 4352874

Abstract:

A biological sterilization indicator (BI) and method of using same. The BI can include a housing, and a container positioned in the housing. The container can contain a liquid and at least a portion of the container can be frangible. The BI can further include a first chamber and a second chamber. The second chamber can include at least one source of biological activity. The BI can further include a first fluid path positioned to fluidly couple the first chamber and the second chamber, and a second fluid path positioned to allow displaced gas to move out of the second chamber. The method can include moving displaced gas out of the second chamber via the second fluid path as a sterilant is moved into the second chamber via the first fluid path and/or as the liquid is moved into the second chamber via the first fluid path.

International Classification:

A61L 2/28
C12Q 1/22

Abstract:

A biological sterilization indicator, system, and methods of determining the effectiveness of a sterilization process. The biological sterilization indicator can include a locus of spores, a reservoir containing a liquid, and a sterilant path positioned to provide fluid communication between ambience and the locus of spores. The reservoir can have a closed state in which the reservoir is not in fluid communication with the locus of spores and an open state in which the reservoir is in fluid communication with the locus of spores. The biological sterilization indicator system can include the biological sterilization indicator and a detection device adapted to be coupled to the biological sterilization indicator. In some embodiments, the method can include assaying the spores for a detectable change in a characteristic, and detecting substantially all of the detectable change.
