ITI in Mechanic Medical Electronics

Mechanic Medical Electronics is a medical electronics vocational trade. The duration of trade is two years with four semesters of six months each. There are many topics to which students are introduced during teaching hours such as maintaining different medical equipment like defibrillators, imaging devices, patient monitors, radiology and laboratory devices; and electric wheelchairs, defibrillators, beds and imaging equipments. There are many ITIs in the country offering this trade because of its job orienting nature. After passing it successfully, there are many areas where they can start work as job.
