Publication number: 20220062887Abstract: A mechanically-actuated vacuum-controlled fluid collection system includes a mechanically-actuated vacuum controller (MAVC) to draw fluid into a chamber through the opening to the chamber. The system may include a releasable seal to seal the opening, and the MAVC may include a spring-loaded plunger to create a vacuum within the chamber when sealed. The system includes multiple fluid chambers, and may further include a single actuator or multiple corresponding actuators. The system may be configured to add a pre-loadable reagent to fluid drawn into the one or more chambers, and may be configured to add the reagent in proportion to a volume of the fluid. The system may be controllable to release collected fluid to another device, such as for assay and/or transport. The system may be configured to draw a liquid biological sample such as urine, and may include a fluid interface to draw fluid from a biological sample container.Type: ApplicationFiled: November 10, 2021Publication date: March 3, 2022Inventors: Brandon T.

Publication number: 20210068730Abstract: A blood sample collection and/or storage device includes a medium, such as a membrane or microstructured environment for storing a body fluid sample such as a blood sample. The medium has hydrophobic patterns formed thereon or therein to define precisely dimensioned channels for fluid flow or fluid retention. Break lines in the medium defined predetermined areas (or volumes) of the medium. After sample collection, the medium may be broken apart along the break lines to obtain a precisely measured amount of the fluid sample.Type: ApplicationFiled: September 4, 2020Publication date: March 11, 2021Inventors: Brandon T.
