This invention is a method for collecting a blood sample and storing its plasma. It uses a small device that creates a gentle vacuum to pull a patch of skin into a cup-like opening, then pierces the skin to collect blood. The collected blood is then moved into a separate storage cartridge, where the plasma can be stored.
Why it matters: Filed before significant advancements in miniaturized, disposable vacuum systems and microfluidic plasma separation. The method's focus on enhanced blood collection and plasma storage now benefits from these integrated technologies.
