Medical Equipment & Systems I

Catalog description

Introduction to the field of biomedical engineering technology, electrical wiring devices, theories of measurement, cardiovascular systems and ECG monitor operation. BE T 201 Medical Equipment & Systems I (5) This course introduces the student to electrical safety standards andrelated wiring devices, methods and systems. Grounding and leakage current is studied so the student understands the causes of leakage current, safety limits, measurement and safe control of medical devices.Electrical wiring devices, over current protective devices, power quality devices and simplified hospital electrical distribution systems are discussed in relation to the electrical power delivery and quality required for medical devices. The electro-physiological theories of measurement, sensors, electrodes and measurement errors are discussed to provide an understanding of how signals are detected on the human body. A variety of transducers will be studied that are used with medical devices, such as: pressure, temperature, audio, relays, solenoids, lighting, video displays, motors, printers and batteries. The blood, heart, and cardiovascular system is studied in detail, as well as the electro-physiological signals of the heart. The normal and many abnormalelectrocardiograph signals are studied pursuant to a thorough understanding of the function and operation of the heart. The electrocardiograph (ECG) machine is studied from an electrical/electronic design perspective so the student has an understanding of the electronic circuits required to measure and displaythe human ECG signal. The controls, operation, electrical safety testing, performance testing and general design of an ECG monitor is studied so the student has a full understanding of its operation, usage and preventative maintenance testing.Topics covered include: - electrical safety - grounding, leakage current and protective systems -electrical wiring devices, over current protective devices, and isolated power -power quality, disturbances and corrective methods -simplified hospital electrical distribution system -theory ofmeasurement: terms, factors, and errors -electrodes, sensors, and transducers devices and circuits -cardiovascular anatomy and physiology -bio-potentials: electro-conduction system of the heart -common ECG waveforms: normal and abnormal -ECG monitor application and connections to patient
