Abstract: A needle including a cannula having a multi-beveled point is disclosed. The multi-beveled point includes a primary bevel, two middle bevels, and two tip bevels. Each of the middle bevels extends between the primary bevel and one of the tip bevels. The primary bevel is provided on the cannula at a first angle of inclination and a first angle of rotation, the two middle bevels are provided on the cannula at a second angle of inclination and a second angle of rotation, and the two tip bevels are provided on the cannula at a third angle of inclination and a third angle of rotation. The third angle of inclination is greater than the second angle of inclination, the second angle of inclination is greater than the first angle of inclination, and the second angle of rotation is equal to the third angle of rotation.

Abstract: 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.

Abstract: 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.
