Title:
INDUCTION HEATING CIRCUIT FOR MEDICAL SHARPS REMOVAL DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/010019
Kind Code:
A3
Abstract:
Induction heating from an induction coil (108) is used to separate a metal medical sharp (144) from its holder (142) by applying a high-frequency oscillating magnetic field that excites eddy currents and resistance heating in the sharp. The heated metal sharp melts the adhesive or plastic securing the sharp to its holder. The use of induction heating is advantageous in that it does not require direct contact between the electrical circuit and the sharp or its holder. The heating can also act to sterilize the sharp and thereby render it less hazardous at the same time that it separates the sharp from its holder. The induction coil can have a stepped or conical shape to concentrate the RF energy at the interface between the metal sharp and its holder.
