Study Notes
Medical Technology Overview
- Medical technologists, or clinical laboratory scientists, perform essential lab tests that inform doctors' diagnostic and treatment decisions.
- Precision in lab results is critical as inaccuracies can have life-or-death consequences.
- Responsibilities include conducting a range of tests from simple procedures, like pregnancy tests, to complex analyses for diseases like diabetes and cancer.
Definitions of Medical Technology
- Heinemann: Application of scientific principles for laboratory tests aiding in diagnosis and treatment.
- Fagelson: Concerned with laboratory analyses for health and disease management.
- Walters: Focuses on laboratory analyses necessary for diagnosing and maintaining health.
- R.A 5527: Examines tissues and fluids to assist physicians in disease diagnosis and health promotion.
Historical Context of Medical Technology
- Diseases were initially viewed as mysterious phenomena linked to environmental factors and body fluids.
- Hippocrates, known as the Father of Medicine, emphasized the qualitative assessment of disorders through the observation of bodily fluids.
- The four humors theory—phlegm, blood, yellow bile, and black bile—was foundational in ancient medical thought surrounding disease causes.
Key Historical Figures and Innovations
- Hippocrates: Linked urine characteristics to kidney disease and established early principles of diagnosis based on urine examination.
- Galen: Coined "diarrhea of urine" to describe diabetes and connected fluid intake to urine volume.
- Uroscopy became a standard practice in medieval Europe, with the first detailed book on urine characteristics published by 900 AD.
Evolution of Medical Technology
- 11th Century: Medical practitioners faced restrictions against physical examinations, relying on patient-described symptoms for diagnosis.
- 18th Century: Mechanical techniques and cadaver dissections advanced the objectivity of diagnoses, although public reluctance persisted towards physical examinations.
- 19th Century: Introduction of machines for diagnosis marked a transition to more systematic medical practices, allowing physicians to employ technology in disease detection and treatment.
Impact of Medical Technology
- The progression of medical technology served as a response to high mortality rates during events like the Bubonic plague, transforming medicine into a remedy for widespread illnesses.
Introduction to Medical Technology
- Medical technologists play a critical role in hospitals, conducting tests that inform doctors' diagnoses and treatments.
- Accuracy in test results is vital as these professionals may directly influence life-and-death situations.
- Responsibilities range from simple tests like pregnancy tests to advanced diagnostics for diseases such as diabetes, AIDS, and cancer.
Definitions of Medical Technology
- Heinemann: Application of natural, physical, and biological sciences in laboratory procedures for disease diagnosis and treatment.
- Fagelson: Focuses on laboratory determinations used in diagnosis and health maintenance.
- Walters: Health profession specializing in laboratory analyses essential for disease management and health.
- R.A. 5527: Describes medical technology as an auxiliary branch that examines bodily tissues and fluids to assist in disease diagnosis and health promotion.
Historical Context of Medical Technology
- Early human understanding of disease linked it to environmental factors and body fluid imbalances.
- Hippocrates, the Father of Medicine, and Galen explored the association between the four humors and diseases, influencing medical thought.
- Ancient practices included uroscopy and qualitative assessments based on urine characteristics.
Evolution of Medical Technology
- 11th Century: Medical examinations were primarily subjective, relying on patient descriptions rather than physical assessments.
- 18th Century: Introduction of mechanical techniques and cadaver dissection improved diagnostic accuracy.
- 19th Century: Machines began to assist in diagnoses, with significant inventions such as:
- Spirometer: Measured lung capacity.
- Sphygmomanometer: Measured blood pressure.
Technological Breakthroughs in Medical Technology
- Stethoscope (1816): Invented by Rene Laennec; first diagnostic tool for listening to heart and lung sounds.
- Microscope (1840): First practical microscope developed by Antonie van Leeuwenhoek.
- Ophthalmoscope (1850): Invented by Hermann von Helmholtz for internal eye examination.
- Laryngoscope (1855): Created by Manuel Garcia for throat examination.
- X-ray (1859): Discovered by Wilhelm Roentgen, enabling non-intrusive viewing of the body's internal structures.
Notable Innovations and Developments
- 1903: First Electrocardiograph by William Einthoven measured heart's electrical changes.
- 1910: Kenny Method introduced by Elizabeth Kenny for polio treatment.
- 1939: First heart-lung bypass machine designed by John Gibbon.
- 1941: Cardiac catheterization and angiography advancements came through material science developments.
Development of Medical Technology in the United States
- 1918: John Kolmer's publication led to Pennsylvania's law mandating equipped clinical laboratories staffed by trained technicians.
- 1922: American Society for Clinical Pathology founded to promote cooperation among medical professionals.
- 1950: Medical technologists sought formal recognition and licensure for their qualifications.
Medical Technology's Historical Progress in the Philippines
- 1578: San Lazaro Hospital established by Franciscans for the poor.
- 1901: Bureau of Government Laboratories was formed under Act No. 156.
- 1941: Aerial assault by Japan impacted Manila; subsequent medical developments followed.
- 1954: Manila Sanitarium opened the first Medical Technology school, marking a formal education milestone.
Post-War Medicine in the Philippines
- After WWII, the 26th Medical Infantry of the U.S. Army introduced clinical laboratories and trained high school graduates as medical technicians.
- The Manila Public Health Laboratory emerged from military initiatives, ensuring medical technology's integration into the public health system.
