Biomedical Metrology


Taking a concern of public health in our country, this group is actively engaged in fabricating indigenous point-of-care devices using novel biocompatible sensing materials for the diagnosis of chronic disease viz. renal dysfunction and heart disease by quantifying their markers. We have taken initiatives to establish standardization of medical equipments. New facilities are being set up for the calibration and testing of biomedical equipments viz. the defibrillator machine, defibrillator analyzer and the electrical safety analyzer in NPL. Defibrillator is used for critical & emergency safety of the patient suffering from cardiac arrest and is commonly available in hospitals, ambulances, medical institutes and public places. However, if the amount of energy applied to the patient is lower than the pre-set value, the signal applied onto a patient will not be sufficient. Alternatively, a high amount of energy applied to the patient than the pre-set value would be detrimental to human life. To measure the energy delivered by a defibrillator, defibrillator analyzers are used. In order to ensure the effectiveness and safety of the defibrillators, the output energy level should be calibrated regularly.

Defibrillator & Defibrillator Analyzer

The calibration of another biomedical device namely electrical safety analyzer is essentially required for electrical safety testing to ensure safe operating standards for any product that uses electricity. Various governments and agencies have developed stringent requirements for electrical products that are sold world-wide. To conform to such standards, the products must pass safety tests such as the high voltage test (also called as Dielectric voltage-withstand test or high potential test), Insulation Resistance Test, Ground (Earth) Bond & Ground Continuity Test & Leakage Current Test (also called as Line Leakage Test, Earth Leakage Current Test, Enclosure Leakage Current Test or Patient Leakage Current Test). These tests are described in IEC 60335, IEC 61010 and many other national and international standards. With increasing requirement for calibration of these biomedical instruments we will be providing calibration services using standards with accuracy traceable to International system of units (SI) through a National Measurement Institute like CSIR-NPL.
