Microneedle-Based Device for the One-Step Painless Collection of Capillary Blood Samples

摘要

The advancement of point-of-care diagnostics and the decentralization of healthcare have created a need for the simple, safe, standardized and painless collection of blood specimens. Here, The design and implementation of a capillary blood-collection device is more convenient and less painful than a fingerstick and venepuncture, and collects 100μl of blood. The technology integrates into a compact, self-contained device an array of solid microneedles, a high-velocity insertion mechanism, stored vacuum, and a microfluidic system containing lithium heparin anticoagulant.
