A portable, manual device intended to be used for the external treatment of insect bites or stings (e.g., from mosquitoes) through dispatch of a small (e.g., 13 kV) piezeoelectric charge to the affected region of the skin. The charge is intended to localize the poison and inhibit histamine release therefore reducing itching and inflammation. It typically consists of a pocket-sized, hand-held housing containing piezocrystal with a trigger mechanism. It is available [non-prescription] over-the-counter (OTC) for home-use. This is a reusable device.
