The lack of safe, reliable, automated and clinically acceptable blood sampling has been the main problem precluding the development of real-time systems for blood analysis and subsequent closed-loop physiological function control. While the analysis of a static blood sample in laboratory conditions has been rapidly advancing in reliability and blood volume reduction, non-invasive real-time blood analysis performed in vivo (while the blood is circulating in the body) has been elusive and unreliable. In this study we propose an innovative idea for semi-invasive blood sampling and analysis, which resembles the operation of a mosquito. At a miniature scale the proposed system does penetrate the skin to extract a static blood sample for further analysis, but the extent of this penetration, and the fact that it can be made painless, is particularly attractive for such applications as automated glucose analysis for closed-loop control of insulin infusion (artificial pancreas), continuous drug monitoring, or even periodic DNA analysis for security and identification purposes. These design aspects are described, and a specific implementation, applying MEMS (Micro Electro Mechanical Systems) technology, is suggested. The proposed microsystem is a matrix of individually controllable e-Mosquito™ cells, packaged in a disposable patch and attached to the skin, could be an avenue for real-time semi-invasive blood analysis and diagnostics.

A needle is provided, having a closed tip configured to minimize tissue damage from penetration of the needle. The needle includes a tubular side wall defining an internal bore. The needle further includes an end wall angled relative to the needle's longitudinal axis and disposed at the distal end of the needle. The needle defines a distal opening spaced from the closed tip, providing access to the internal bore to facilitate fluid transfer. Preferably, the needle is configured to create a crescent-shaped penetration mark. The number and positioning of openings can be varied across embodiments of the invention, while maintaining a closed tip. For example, in certain embodiments, the needle comprises two distal openings defined by the side wall. A distal opening can also be provided by the end wall singly or in combination with additional distal openings.
