Seventh Sense Biosystems has developed a unique tool to perform routine blood draws in a quick, painless, and hidden manner. The TAP blood collection device adheres to a patient's arm using an attached gel pad, and with the touch of a single button can draw a 100ul whole blood sample. The blood is drawn from the capillary beds near the surface of the skin using 30 microneedles, causing minimal discomfort and without the patient ever seeing the needles or blood. A window on the front of the device shows when the blood drawing is complete, and the unit then stores the sample until it is ready to be analyzed.
