摘要: A first aspect of the present invention provides for devices to facilitate the release of sample materials from sample acquisition devices. The device comprises an abrasion element comprising at least one constriction or projection. A second aspect of the present invention provides for methods in which to use the devices to facilitate the release of sample materials from a sample acquisition device. Optionally, the device may contain at least one reagent to facilitate the release and/or detection of a microorganism, or component thereof, in a sample. Preferably, the devices and methods may be used in conjunction with a liquid medium in which the sample may be further processed.

摘要: Devices to process a sample are configured to releasably attach a sample acquisition device to a drive mechanism that provides rotational and/or vibrational motion to the sample acquisition device. The devices can be used in sample processing methods to dislodge sample materials from the sample acquisition device. Sample processing methods using rotational or vibrational motion may further include the use of a liquid medium into which the sample is released. Sample processing methods may further include the detection of an analyte in the sample.

摘要: A sample acquisition device includes a body comprising a plurality of sample acquisition regions defined by at least a first wall and a second wall oriented nonparallel to the first wall. In some embodiments, the body defines a plurality of apertures that define a plurality of sample acquisition regions. In other embodiments, the walls extend from the body, and the sample acquisition regions are defined between the walls. The sample acquisition regions may be configured in some embodiments such that a user may acquire a sample by rotating the body in a first direction relative to a sample source and may release the sample by rotating the body in a second direction that is substantially opposite to the first direction. When rotated in the first direction, at least one of the first or second walls defines a surface that is inclined into a sample acquisition region.

摘要: A sample acquisition device includes a capillary array configured to draw in a sample and retain the sample by capillary action. The capillary array may be coupled to an elongated member, such as a stem or a hollow tube, which defines a longitudinal axis extending in a first direction. In some embodiments, the capillary array defines a major sample acquisition surface that extends in a second direction different than the first direction. A ratio of the major sample acquisition surface area to maximum volume retained by the capillary array may be selected to minimize physical binding between the capillary array and sample. In some embodiments, the device may include a feedback mechanism to indicate the relative pressure applied to a sample source with the sample acquisition device. In addition, in some embodiments, the sample acquisition device may include a suction source to help draw the sample into the capillary array.
