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.
Claims6
A syringe needle disposer, comprising:
- means for receiving and supporting a syringe needle in a downwardly extended position within said means, said supporting means being formed so as to permit the needle, when forced, to slide in a horizontal direction;
- means for generating a magnetic flux passing through said syringe needle placed in said supporting means so that said magnetic flux which is induced by an alternate electric current having a predetermined electric power and a predetermined frequency causes said syringe needle to at least partially melt by induction heating;
- means connected to said generating means for controlling said generating means in accordance with a diameter of said syringe needle;
- a pressure plate positioned in said supporting means and supporting thereon a tip of said syringe needle;
- and
- means for pressing said pressure plate against said needle so that, as said needle is partially melted and slid in said supporting means in the horizontal direction, an axial hole of said needle becomes completely closed.
