Study Notes
Diagnostic Medical Breakthroughs
- Stethoscope: Invented by Rene Laennec in 1816, it acquires information about lung sounds and heartbeats, revolutionizing patient examination.
- Microscope: Developed by Antonie van Leeuwenhoek in 1840 for medical purposes, it allows for detailed examination of minute structures due to advances in lens technology and reduced costs.
- Ophthalmoscope: Created by Hermann von Helmholtz in 1850, this instrument enables inspection of the interior of the eye, enhancing eye care diagnostics.
- Laryngoscope: Introduced by Manuel Garcia in 1855, it employs two mirrors to visualize the throat and larynx, aiding in respiratory health assessments.
- X-ray: Discovered by Wilhelm Roentgen in 1859, this technology allows non-invasive viewing of internal structures, essential for diagnosing conditions like pneumonia and tuberculosis, particularly post-WW2.
- Electrocardiograph: Developed by William Einthoven in 1903, this device measures electrical changes in the heart, crucial for diagnosing cardiac conditions.
- Kenny Method: Pioneered by Elizabeth Kenny in 1910, it applies hot packs and muscle manipulation for polio treatment, laying groundwork for physical therapy.
- Sylvia Stretcher: Invented in 1927 by Elizabeth Kenny, this new stretcher design facilitates the safe transportation of patients in shock.
- Drinker Respirator: Created in 1927 by Philip Drinker, this artificial respirator aids patients with paralytic poliomyelitis in maintaining respiratory function.
- Heart-Lung Machine: Developed by Hermann von Helmholtz in 1939, it supports body functions during heart surgery, acting as a substitute for the heart and lungs when they are stopped.
- Cardiac Catheterization and Angiography: Initiated by Forsmann in 1929 and further developed between 1930-1940 by Moniz, Reboul, and Rousthol, with safe methods discovered by Cournard in 1941, this technique visualizes heart and lung vessels using a cannula and radiopaque dye.
- Electron Microscope: Created by Ernst Ruska and Max Knoll in 1931, it allows for high magnification (initially 400x), facilitating visualization of small cells, including tumor cells.
- Tomography: Developed by Godfrey Hounsfield in 1972, this technique adapts computers for medical imaging, enhancing diagnostic capabilities.
- Magnetic Resonance Imaging (MRI): Pioneered by Raymond Damadian in 1977, he performed the first full-body scan, significantly improving internal imaging.
Other Medical Technology Breakthroughs
- Prosthetics: Developments include artificial heart valves, blood vessels, functional electromechanical limbs, and reconstructive skeletal joints, enhancing quality of life for patients with disabilities.
- Robotics: Integration of robotics in surgeries and patient care improves precision and efficiency.
- Keyhole Surgery Procedures: Minimally invasive procedures reduce recovery times and improve patient outcomes.
- Genetic Engineering: Advances in genetic manipulation hold potential for treating genetic disorders and improving health outcomes.
- Telemedicine / Information Technology: Enhances patient access to healthcare through remote consultations and digital health records, improving efficiency in medical practices.
