Study Notes

History of Medical Technology: Overview

In the 11th century, physical examinations were not permitted; diagnosis relied on patient self-reports and observations.
The 18th century introduced mechanical techniques and cadaver dissection for more accurate diagnostics and anatomical understanding.
The 19th century saw the adoption of machines for diagnostics and therapeutics, with key inventions like:
- Spirometer by John Hutchinson
- Sphygmometer by Jules Herrison
- Advances in chemistry significantly contributed to diagnosing diseases like diabetes, anemia, diphtheria, and syphilis.

Notable Inventions in Medical Technology

Stethoscope (Rene Laennec, 1816)
Microscope (Antonie van Leeuwenhoek, 1840)
Ophthalmoscope (Hermann von Helmholtz, 1851)
Laryngoscope (Manuel Garcia, 1855)
X-ray (Wilhelm Roentgen, 1896)

Development of Medical Laboratories

Mid-1800s: Laboratories for analyzing medical specimens emerged, spearheaded by chemical experts.
Mid-1900s: Technical laboratories regulated by the Centers for Disease Control and Prevention (CDC) were established in the US to support medical diagnostics.
Early 20th century improvements included integrating scientific discoveries with healthcare advancements.

Major Technological Advancements (20th Century)

Electrocardiogram by William Einthoven (1903)
Kenny Method by Elizabeth Kenny (1910)
Drinker respirator by Philip Drinker (1927)
Heart-lung machine by Hermann von Helmholtz (1939)
Cardiac catheterization and angiography by Andre Cournand (1941)

Modern Trends in Medical Technology

Integration of technology with science has led to innovations like:
- Electron microscopes
- Advanced medical imaging technologies
- Prosthetic devices
Ongoing breakthroughs in robotics, surgical procedures, genetic engineering, and telemedicine.

Historical Figures in Medical Technology

Hippocrates:
- Known as the "Father of Medicine" and author of the Hippocratic Oath.
- Advocated qualitative assessments of disorders and recognized the four humors: blood, phlegm, yellow bile, black bile.
- Used methods such as urine tasting and observation for diagnosis.
Galen:
- Noted the relationship between diabetes and urine characteristics (diarrhea of urine).
- Studied fluid intake and its effect on urine volume.

Medical Practices in Medieval Europe

In medieval times, diagnosis techniques included water casting (uroscopy).
By 900 AD, the first book detailing the characteristics of urine was published.
Medical advancements were stimulated by high mortality rates from plagues and diseases.
