Study Notes

Overview of Medical Technology

Also referred to as Clinical Laboratory Science, encompasses the collection, analysis, and laboratory evaluation of human biological samples.
Supports patient diagnosis, management, treatment, and health maintenance.
Integral to laboratory medicine, involves diagnostic and therapeutic applications of science and technology.

Historical Figures in Medicine

Hippocrates (460-370 BC): Known as the "Father of Medicine"; introduced the Hippocratic Oath; utilized urine analysis and physical observations for disease diagnosis.
Galen: Greek physician who conducted qualitative assessments of bodily fluids; described diabetes as "diarrhea of urine."

Milestones in Medical Diagnostics

Medieval Period: Dominance of "water casting" (uroscopy) for diagnosis.
900 AD: First book describing urine characteristics (color, density).
11th Century: Medical practitioners' reliance on patient symptom descriptions due to the ban on physical examinations.
19th Century: Introduction of machines in medical diagnostics.

Key Inventions in Medical Technology

Stethoscope (1816): Invented by René Laennec, instrumental for lung and heart assessment.
Microscope (1840): Improved by Antonie van Leeuwenhoek, enabling enhanced biological study.
Sphygmomanometer (19th Century): Developed by Jules Herissons for blood pressure measurement.
Electrocardiograph (1903): Created by William Einthoven to analyze heartbeats’ electrical activity.
X-ray (1859): Discovered by Wilhelm Roentgen; allows non-invasive internal body imaging.
Laryngoscope (1855): Developed by Manuel Garcia for throat examination.

Significant Medical Advances

Kenny Method (1910): Pioneered by Elizabeth Kenny for physical therapy, particularly for polio treatment.
Drinker Respirator (1927): Created by Philip Drinker; assisted respiratory function in polio patients.
Heart-Lung Machine (1939): Innovated by Hermann von Helmholtz for cardiac surgeries.

Contributions of Pioneering Scientists

Antonie van Leeuwenhoek: First to describe microorganisms, known as the "Father of Microbiology".
Edward Jenner: Developed the first vaccine for smallpox in 1796 after testing a dairymaid's cowpox lesions.
Louis Pasteur: Founder of medical microbiology; discovered the role of microorganisms in fermentation and disease prevention.
Joseph Lister: Innovator of antiseptic procedures in surgery; emphasized the necessity of preventing bacterial contamination.
Robert Koch: Established the bacteriology field; identified pathogens like those causing anthrax and tuberculosis.
Elie Metchnikoff: Discovered phagocytosis, contributing significantly to the understanding of immune responses.
