Study Notes
History of Medical Technology in a Global Context
- Early medical diagnosis regarded disease as a mystery linked to environmental and bodily interactions.
- Hippocrates and Galen, prominent ancient Greek physicians, advanced quantitative assessment of disorder through body fluid analysis, specifically the four humors: blood, phlegm, yellow bile, and black bile.
- Hippocrates pioneered the practice of examining urine by tasting it, listening to lungs, and observing physical symptoms; he connected urine characteristics, such as bubbles and pus, to kidney disease.
- Galen termed diabetes as "diarrhea of urine" and identified the link between fluid intake and urine volume.
- In medieval Europe, uroscopy was a prevalent diagnostic method, with physicians facing public penalties for neglecting urine examination.
- By 900 AD, the first comprehensive book on urine characteristics, detailing aspects like color and density, was published.
Medicine and Medical Technology Advancement
- The high mortality rates from plagues and diseases prompted significant advancements in medicine and medical technology.
11th Century - 19th Century Developments
- Early 11th-century medical practitioners could not perform physical examinations; they relied on patient symptom descriptions and personal observations.
- By the 18th century, mechanical techniques and cadaver dissections became vital for objective diagnoses and anatomical understanding.
- The 19th century introduced machines for medical diagnostics and therapies, such as John Hutchinson's spirometer for lung capacity and Jules Herisson's sphygmomanometer for blood pressure measurement.
- The application of chemistry in this era was critical for diagnosing diabetes, anemia, diphtheria, and syphilis.
Specialization in Medical Technology
- The introduction of mechanical and chemical devices led to a shift from general practice to medical specialization due to the influx of patients and growing medical knowledge.
- Increased complexity in medical machinery necessitated specialized technical expertise, fostering collaboration among different medical specialties.
- This shift resulted in a more organized medical service framework within hospitals, necessitating the management of extensive patient data for accurate diagnosis and treatment.
- The rise in patient data led to greater demands for information technology and an increase in the need for medical technicians; by 1969, 80% of medical professionals were non-physicians.
- Technicians became essential for operating medical technologies, while patients needed education regarding their medical tests.
Technology as Basis for Diagnostic Assessments
- The reliance on technology shifted diagnostic assessments away from traditional face-to-face patient-physician interactions towards dependence on technological outputs rather than subjective symptom descriptions.
