In developing countries, most hospitals are lacking in needle safety. In regions surveyed by the world health organization (WHO), the reported number of needle stick injuries in developing world countries ranged from .93 to 4.68 injuries per person and per year, which is five times higher than in industrialized nations.

There are a lot of infections related with needle reuse problems especially in developing countries like Ethiopia, since the most common method for disposing of used hypodermic needle syringes is a sharps container and general waste incinerator in the hospital. A study by World Health Organization indicates that about 12 billion injections are adminis- tered each year. The most clinical significance that we approach our design is the common method for disposing of used hypodermic needle syringes is a "sharps" container. A sharps container merely is a plastic container into which the used hypodermic needle syringes are placed which lead to unintentional contact with a contaminated needle and exposing the contaminated needles.

Our design consideration generally consists two main parts: Electrical parts, the power development part for the proper destruction of the needle and the syringe to develop a large amount of current from a wall socket which helps to destroy a needle, consisting step down transformer, bread board, switch, Full wave rectification, fuse, resistor and flat capacitor for power filtration, while the mechanical parts consist a frame box of metal which is made up of carbon plated metal having high melting point to resist the heat like carbon metal which is one of the best heat resistant metal to melt a nee- dle. The needle destroying means comprises two overlapping flat electrodes preferably comprised of high grade carbon. The electrodes may be comprised of any suitable electrode material; however, high grade carbon provides the preferred electrical conduction level and has a satisfactory lifetime.

Finally, the designed device is that the user simply holds the injector and plugs the used needle head into the needle-head destroy device so that the needle is in contact with both non-contacting electrodes. At this moment the used needle will absorb the strong current resulting from short-circuit of the two electrodes, while the detachment, and the collection of the needles can be done all at once to s simplify the operation.
