Development of the Electric Lancing Device and the Lancet to Prevent the Secondary Contamination by Needlestick Injury

This paper deals with the development of the safety lancet and the electric lancing device. The safety lancet, in which a needle and a protective cap become one body, is designed. It is to prevent the secondary contamination by needlestick injury because the needle is always in the protective cap except for a moment of blood-gathering. The electric lancing device powered by batteries is devised to be operated by the moving rod of solenoid hitting the lancet. and to be used after selecting the repeat or the single hitting mode. The impact force by a hitting rod, the expected life of battery and etc. are measured for product development. This lancing device can be also used for the bloodletting device of the oriental medicine.
