Publication number: 20230415146Abstract: A mechanical separator for separating a fluid sample into first and second phases within a collection container is disclosed. The mechanical separator may have a separator body having a through-hole defined therein, with the through-hole adapted for allowing fluid to pass therethrough. The separator body includes a float, having a first density, and a ballast, having a second density greater than the first density. A portion of the float is connected to a portion of the ballast. Optionally, the float may include a first extended tab adjacent a first opening of the through-hole and a second extended tab adjacent the second opening of the through-hole. In certain configurations, the separator body also includes an extended tab band disposed about an outer surface of the float. The separator body may also include an engagement band circumferentially disposed about at least a portion of the separator body.Type: ApplicationFiled: September 12, 2023Publication date: December 28, 2023Inventors: Jamieson W.

Patent number: 11318459Abstract: A method for detecting the presence of a microorganism in a fluid sample is disclosed. The method includes providing a fluid specimen within a specimen collection container having a sidewall defining an interior therein. The interior includes a mechanical separator adapted for separating the fluid sample into first and second phases within the specimen collection container and a sensing element capable of detecting the presence of a microorganism disposed therein. The method includes subjecting the specimen collection container to applied rotational force to isolate a concentrated microorganism region. The method also includes detecting by a sensing element the presence or absence of a microorganism within the concentrated microorganism region.Type: GrantFiled: September 4, 2013Date of Patent: May 3, 2022Assignee: Becton, Dickinson and CompanyInventors: Song Shi, Mei Yang, Klaus W.
