Abstract
A system that is suitable for extracting plasma from blood received from a blood supply is provided. The system comprises a housing, an inlet opening for receiving the blood, a filtration chamber comprising a membrane, and a plasma compartment. The membrane forms a barrier between the blood and the plasma extracted from the blood, and the plasma compartment collects the plasma extracted from the blood. In some embodiments, the system comprises a plasma flow path compression chamber for pulling plasma across the membrane. In some embodiments, the system comprises a blood flow path compression chamber for facilitating blood flow. Some embodiments of the system further comprise means for measuring plasma and blood analytes using spectroscopic and biosensor techniques.
