CNon-optionalAbbreviated answers (5 points per question, 20 points) - a brief description of the main elements of electrical safety tests for medical devices. - description of the main points for detecting the quality of optical images of medical equipment. - describe the meaning of medical equipment reliability tests. - briefly describe the attention given to the one-time use of medical devices. Physicological analysis of the subject (10 minutes each, 20 minutes) - an existing medical electronic thermometer with inaccurate readings at measurements of body temperature. Please analyse the possible causes and indicate the method of detection. - the image of an ultrasound diagnostic device is false. Please analyse the reasons that may lead to hypocrisy and how detection and screening are carried out. 23.Case analysisQuestion (10 minutes) a new batch of blood sugar units was purchased in a hospital and, after some time in use, the results were found to be more biased. Please analyse the possible causes and indicate how they should be tested and addressed. 24. Material analysis (10 minutes) material: a pacemaker produced by a medical equipment company found in clinical trials an inaccurate monitoring of the heart rate following the use of some patients. Question: please analyse the reasons that may lead to inaccurate heart rate monitoring and indicate how this issue should be monitored and improved. 25. Comprehensive application (10 points) c. T. Equipment at a hospital has recently deteriorated in quality, blurry and false images. Please provide a comprehensive analysis of possible causes and develop a complete testing and maintenance programme. Answer: 1. B2. C3. B4. D6. A6. B7. C9. A10. C11. C12. A13. D14. C15. A16. A16.

Electrical safety checks include ground-to-ground electrical resistance detection to ensure that equipment is well located to prevent leakage; outer-hull protective grade tests to see if its protection is in compliance with standards; and insulated electrical resistance tests to detect electrical insulation. To detect visual clarity in the image mass points of the medical optical device, to observe whether the details of the image are clear; contrast, to see whether it is appropriate to contrast the image clearly and implicitly; and resolution, to detect the smallest details of the image that can be identified. The purpose of medical equipment reliability testing is to ensure that the equipment fulfils the required functions within the prescribed conditions and time frame, to reduce the occurrence of malfunctions and to ensure medical safety and effectiveness. One-time medical devices are used to detect the sealing of packaging to prevent contamination by micro-organisms, material conformity, release of hazardous components, etc. 22. Medical electrostatic thermometers may not be allowed for sensor failure, circuit problems, etc. The test method is to check for damage to the appearance and then test the sensor output with a standard body temperature to check for damage to the circuit. Ultrasound diagnostic device images may be faked because of a problem with the probe, inappropriately configured gain etc. Tests are conducted to check the appearance and performance indicators of the probe, adjust parameters such as gains and so forth, observe the evolution of false images, and check whether the equipment parameters are set. 23. The reasons for the deviations in the blood sugar instrument measurements are probably due to expired test paper, inaccuracies in calibration, ageing of internal components of the instrument, etc. The method is to replace the new test paper, check the correctness of the calibration, use standard blood sugar solution calibration, and, if still in error, further check elements such as internal circuits and sensors of the instrument. 24. Inaccuracies in the monitoring of the heart rate can be attributed to poor electrodes exposure, pacemaker programming problems, sensor failure, etc. Check the integrity of the electrodes during testing to see if the pacemaker program is set correctly, test sensor performance using analogue signals, improve based on the results of detection, e.
