5 Essential Medical Machines Used in Hospitals
It took many years to get x-rays machines from the large, cumbersome and fatally dangerous things they were at the beginning to the highly useful and very safe instruments they are today. X-ray machines help doctors diagnose illnesses, detect fractured bones, cavities and foreign objects inside the body. EKG MachineThe first EKG (electrocardiogram) machine was built in 1903 by Willem Einthoven. An EKG machine detects any abnormalities in heart functions by detecting the electrical signals created by the movement of the heart’s muscles. Einthoven assigned the letters P, Q, R, S and T to the various kinds of electrical signals of the heart. His system is still used in modern EKG machines. Ultrasound MachinesIn a similar fashion as sonar, ultrasound machines map the body’s interior tissue and organs by emitting high-pitched sound waves that bounce off internal body structures to produce a visual image of them. Karl Dussik and Ian Donald are the two most well known pioneers of ultrasound technology. In 192, Dussik used ultrasound to examine the human brain and Donald, in the 50s, used ultrasound for diagnostic purposes.
