Is a branch of the allied health professions that deals with the study of various disciples such as chemistry, microbiology, parasitology, blood banking, hematology, clinical microscopy, histology, and histopathology, among others.
What is Medical Technologts?
Medical Technologists, also known as clinical laboratory technologists, perform and analyze the results of complex scientific tests on blood and bodily fluids. These highly trained professionals work in hospitals and independent laboratories sing sophisticated procedures and equipment

MIDDLE AGES
Early Christians believed that disease was either a punishment for a sin or a result of witchcraft or possession.
Basic therapy
PRAYER, PENITENCE AND INVOCATION OF SAINTS.
LAY MEDICINE
based their diagnosis on symptoms, exam. Pulse, palpitation, percussion and inspection of excreta or semen.
Isaac Judaeus
Jewish physician and philosopher, devised guidelines for the use of urine as a diagnostic aid
UROSCOPY
"Water casting" - historical medical practice of visually examining a patient's urine for pus, blood, or other symptoms of disease - patients submits specimen in a decorative flasks Physicians who failed to examine the wine -+ PUBLIC BEATINGS (Jerusalem Code of 1090)
Zacharias Janssen
Opened the doors for scientists who wanted to explore the invisible world we live in and further understand the disease causation.
Jassen Microscope
-Objective-Eyepiece
900 AD
1st book characteristics of urine (e.g. color, density, quality)
Early 11th century
Medical practitioners not allowed to conduct physical exam of the patient's body, relied on the patient description of symptoms and their observation
18th century
Medical techniques and cadaver dissection (accurate diagnosis)
19th century
Physicians began using machines for diagnosis or therapeutics
1969
80%- medical professionals were non-physicians, impelled the need for technicians to be proficient in the use of technology
Spirometer
John Hutchinson__//Use/Measures:Vital capacity of lungs
Sphygmomanometer
Jules Herrison Use/Measures:Blood pressure
RESPIROMETER
- Respiratory Exerciser - A respirometer or incentive spirometer is a device used to help us to keep our lungs healthy. It helps us to take slow, deep breaths to expand and fill our lungs with air. This helps prevent lung problems, such as pneumonia. - The incentive spirometer is made up of a breathing tube, an air chamber, and an indicator (here 3 colored balls). Regular exercise help to open our airways, prevent fluid or mucus from building up in our lungs, and make it easier for us to breathe
STETHOSCOPE
- Rene Laennec (1816) - used to acquire information about the lungs and heartbeats
MICROSCOPE
- Antonie van Leeuwenhoek (1840) - Developed for medical purposes due to advances in lenses and lower costs- instrument that produces enlarged images of small objects, allowing the observer an exceedingly close view of minute structures at a scale convenient for examination and analysis
OPHTHALMOSCOPE
- Hermann von Helmholz (1850) - First visual technology - instrument for inspecting the interior of the eye
LARYNGOSCOPE
- Manuel Garcia (1855) - Using 2 mirrors to observe the throat and larynx
X-ray
-Wilhelm Roentgen (1859) - Discovered by accident that radiation could penetrate solid objects of low density - Allow physicians to view without surgery - Used to dx pneumonia, pleurisy, tuberculosis since WWII
ELECTROCARDIOGRAPH
- William Einthoven (1903) - Measure electrical charges during the beating of the heart
KENNY METHOD
- Elizabeth Kenny (1910) - Pioneering work for Physical Therapy - Treatment for Polio (infantile paralysis) - use hot packs and muscle manipulation
SYLVIA STRETCHER
- New stretcher (1927) - Transporting patients in shock
DRINKER RESPIRATOR
- Philip Drinker (1927) - Help patients with paralytic anterior poliomyelitis recover normal respiration with the assistance of artificial respirator
HEART-LUNG MACHINE
- Hermann von Helmholz (1939) - a machine that temporarily takes over the functions of the heart and lungs, especially during heart surgery
Heart Lung Machine
- A device used in open heart surgery to support the body during the surgical procedure while the heart is stopped. - The heart-lung machine is often referred to as the "pump", and does the work of the heart and lungs during the operation
CARDIAC CATHETERIZATION AND ANGIOGRAPHY
- First operated by Forsmann (1929) - Developed by Moniz, Reboul, Rousthol (1930-1940) - discovered as safe method by Cournard (1941) - made seeing the heart, lung vessels, and valves possible through inserting the cannula in an arm vein and into the heart with an injection of radiopaque dye for x-ray visualization.
ELECTRON MICROSCOPE
- First prototype= 400 power magnification: Ernst Ruska and Max Knoll (1931) - Visualization of small cells including tumor cells
TOMOGRAPHY and MAGNETIC RESONANCE IMAGING
-Adaptation of computers- TOMOGRAPHY: Godfrey Hounsfield (1972) - MRI: Raymond Damadian (1977) - First person to do full body scan of a human being
ANTONIE VAN LEEUWENHOEK
- 1660 - Father of Microbiology Microscope
EDWARD JENNER
1796 - Vaccination to establish immunity to small pox - Impact: Immunology
MARIE FRANCOIS XAVIER BICHAT
- 1880 - Identified organs by their types of tissues - Impact: Histology
