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)

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.
