The quality and efficiency of medical service provided in any hospital depends very much on the proper functioning of the equipment and instruments used by the doctors and other clinical staff. Even under normal and careful use, instruments fail to function properly. The frequency of such failures can be considerably reduced by proper care, maintenance and timely repair. Hence we are providing you with resources which will be help for Care and Maintenance of Ophthalmic Instruments and Equipments.
Objectives of the Training :
After obtaining this training trainees would able to perform :
Using multimeter. Identifying components and knowing their characteristics. Soldering and building simple electrical/electronic circuits. Identifying electrical fuses in instruments and understanding their rating. Calculating the power ratings of instruments to provide (I) proper fuses, (II) proper transformer or voltage stabilizer or UPS as required. Adapting a 110V instrument to work in 220V if the feature is built into the instruments. Building a 220V-110V step down power unit with proper fuse. Changing bulbs in ophthalmoscope, retinoscope, slit lamp, microscope, lensometer, keratometer and fundus camera. Locating electrical faults in equipment like torchlight, surgical lamp, foot switch etc. and rectifying the same.
