BREAKTHROUGH IN MEDICAL TECHNOLOGY

STETHOSCOPE

used to acquire information about the lungs and heartbeats

MICROSCOPE

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. Developed for medical purposes due to advances in lenses and lower costs

OPHTHALMOSCOPE

instrument for inspecting the interior of the eye. First visual technology

LARYNGOSCOPE

Using 2 mirrors to observe the throat and larynx

X-ray

Discovered by accident that radiation could penetrate solid objects of low density.

ELECTROCARDIOGRAPH

Measure electrical charges during the beating of the heart

KENNY METHOD

Pioneering work for Physical Therapy

KENNY METHOD

Treatment for Polio (infantile paralysis)

X-ray

Allow physicians to view without surgery

SYLVIA STRETCHER

Transporting patients in shock

DRINKER RESPIRATOR

Help patients with paralytic anterior poliomyelitis recover normal respiration with the assistance of artificial respirator

HEART-LUNG MACHINE

a machine that temporarily takes over the functions of the heart and lungs, especially during heart surgery

CARDIAC CATHETERIZATION AND ANGIOGRAPHY

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

Visualization of small cells including tumor cells

TOMOGRAPHY and MAGNETIC RESONANCE IMAGING

Adaptation of computer
