Study Notes

History of Medical Technology

  • Ancient Belief: Negative interaction between the environment and the body caused disease.
  • Hippocrates: Father of Medicine, advocated testing urine, listening to lungs, and observing outward appearances for diagnosis. Concluded bubbles, blood and pus in urine indicate kidney or chronic illnesses.
  • Galen: Greek physician, instigated qualitative assessment of disorder through body fluid measurements. Described diabetes as "diarrhea of urine" and established the relationship between fluid intake and urine volume.
  • Medieval Europe (500-1500 AD): Diagnosis by "water casting" (uroscopy) was common. Urine samples in decorative flasks were analyzed. Failure to examine urine could result in public beatings. First book detailing characteristics of urine (color, density, quality) written in 900 AD. Medical practitioners relied solely on patient descriptions of symptoms.
  • 18th Century (1700-1800): Medical techniques and cadaver dissection used to improve understanding of the body's insides, for more objective diagnosis. Laboratories for analyzing medical specimens arose (mid 1800s)
  • 19th Century (1800-1900): Physicians used machines like spirometers (vital capacity) and sphygmomanometers (blood pressure) for diagnosis. Use of chemistry for diagnosing conditions like diabetes, anemia, and diphtheria/syphilis. Technical labs by Centers for Disease Control and Prevention (CDC) used for US medical diagnosis.

20th Century (1900-2000)

  • Advancements: Integration of scientific and technological discoveries improved medical technology. Impacts on various surgical procedures. New technologies: electron microscopy, medical imaging (e.g. tomography, MRI), and prosthetics.
  • Rene Laennec: Invented the stethoscope in 1816 to diagnose heart and lung conditions.
  • Antonie van Leeuwenhoek: Invented the first practical microscope in 1840.
  • Other advancements: Artificial heart valves, blood vessels, functional electromechanical limbs, and reconstructive skeletal joints.

1920s - 1950s

  • William Röntgen: Discovered x-rays (1895), initially accidental discovery, crucial tool to diagnose pneumonia, pleurisy and tuberculosis.
  • William Einthoven: Developed electrocardiograph (1903) to measure electrical changes during heartbeat.
  • Elizabeth Kenny: Developed the Kenny Method for treating polio.
  • Philip Drinker: Invented the Drinker Respirator (1927) for patients with paralytic anterior poliomyelitis to recover normal respiration with artificial respirators.
  • Hermann von Helmholtz: Invented the first Heart-Lung Machine in 1939.
  • Andre van Steirteghem: (1990s) Invented intracytoplasmic sperm injection (ICSI).
  • James Thomson: Invented the first human stem cell line.

Other Medical Developments

  • Development of Clinical Laboratories: The administrative units in clinical labs in hospitals began to be direct by a chief physician; clinical laboratories directed by a chief physician.
  • Laboratory Personnel: Medical Technologists seeking professional recognition, Pathologists monitoring lab results, Phlebotomists, Cytotechnologists, Histotechnologists, and Nuclear Medical Technologists.
  • Emphasis on Professionalism and Ethics: American Society for Clinical Pathology (ASCP) established codes for ethics and training standards.
  • 20th Century Hospitals and Labs: San Lazaro Hospital, William Pepper Lab, Bureau of Government Laboratories, Manila Public Health Laboratory, and other labs.
  • Innovations in Medical Technique: Vaccines against rabies (Louis Pasteur), microorganisms, and procedures such as cardiac catheterization.
