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.

An underarm garment liner for preventing a wearer's perspiration from soiling a garment is disclosed. The liner includes, in its simplest embodiment and in the following order, a non-woven layer, an air laid paper layer, a hygroscopic absorption layer, a water-impervious layer, and an adhesive layer. The non-woven layer is adapted for contacting the wearer's skin and to convey perspiration away from the skin through capillary action to the absorbent air laid paper layer, which draws moisture away from the non-woven layer and conveys the moisture to the hygroscopic absorption layer. The layers are all preferably adhered together through use of hot-melt adhesive, or the like. The water-impervious layer is comprised of a vapor-pervious “breathable” thermoplastic polymer to prevent heat buildup between the liner and the wearer. Deodorizers, antibacterial agents, aloe, vitamin E, and petrolatum may all be further included in the liner 10. A layer of release paper temporarily affixed to the adhesive layer, such that the release paper may be peeled away from the adhesive layer by the wearer in order to expose the adhesive layer prior to use.
