The Black Plague
![Page 3: CHANGES IN MEDICAL TECHNOLOGY BY THOMAS BRAIN. The Black Plague.](https://reader035.fdocuments.in/reader035/viewer/2022062719/56649ef25503460f94c03c6d/html5/thumbnails/3.jpg)
The term “Black Death” is recent. During the plague it was called “The Great Mortality” or “Pestilence”

The Black Death might of killed 200 million Europeans between 1348 and 1351.

Most experts agree that the plague was caused by Yersinia Pestis (or Y.pestis), a bacillus carried by fleas that live primarily on rats and other rodents that were common in medieval dwellings.

On November 2000 study's of tooth pulp in a French plague grave showed the presence of Y.pestis in all 20 samples from three victims.

Virtually nobody suspected the ever- peasant rats and fleas.

X-RAYS
![Page 12: CHANGES IN MEDICAL TECHNOLOGY BY THOMAS BRAIN. The Black Plague.](https://reader035.fdocuments.in/reader035/viewer/2022062719/56649ef25503460f94c03c6d/html5/thumbnails/12.jpg)
X-rays are made in a highly evacuated glass bulb.

The X-ray was discovered in Germany.

The X-ray was first discovered in 1895.

The x-ray was discovered by Wilham Conrad Roentgen.

MRI
![Page 17: CHANGES IN MEDICAL TECHNOLOGY BY THOMAS BRAIN. The Black Plague.](https://reader035.fdocuments.in/reader035/viewer/2022062719/56649ef25503460f94c03c6d/html5/thumbnails/17.jpg)
The MRI was invented by Dr. Raymond Damadian.

Even dogs can get an MRI scanning.

MRIs differ other imaging techniques.

ECG
![Page 21: CHANGES IN MEDICAL TECHNOLOGY BY THOMAS BRAIN. The Black Plague.](https://reader035.fdocuments.in/reader035/viewer/2022062719/56649ef25503460f94c03c6d/html5/thumbnails/21.jpg)
An ECG machine works by recording the electrical impulse emitted by the heart.
![Page 22: CHANGES IN MEDICAL TECHNOLOGY BY THOMAS BRAIN. The Black Plague.](https://reader035.fdocuments.in/reader035/viewer/2022062719/56649ef25503460f94c03c6d/html5/thumbnails/22.jpg)
The biggest part of the ECG machine is the circuity box.

The impulses are recorded in pairs.

Immunisation
![Page 25: CHANGES IN MEDICAL TECHNOLOGY BY THOMAS BRAIN. The Black Plague.](https://reader035.fdocuments.in/reader035/viewer/2022062719/56649ef25503460f94c03c6d/html5/thumbnails/25.jpg)
Immunisations saves lives.
![Page 26: CHANGES IN MEDICAL TECHNOLOGY BY THOMAS BRAIN. The Black Plague.](https://reader035.fdocuments.in/reader035/viewer/2022062719/56649ef25503460f94c03c6d/html5/thumbnails/26.jpg)
Immunisation prevents 2-3 million deaths per year.
