Abstract

A syringe needle disposer includes a setting section for setting waste syringe needles and a magnetic field generating section for providing a high frequency alternating field to the setting section. When the high frequency alternating field is activated, a magnetic path of the magnetic flux passing through the waste syringe needle set in the setting section is formed, thereby induction-heating the syringe needle to soften the needle and to round its tip and to close an axial hole of the syringe needle. The sharp edge of the softened syringe needle may be blunted by contacting a pressure plate under pressure.
