First recorded attempt at blood transfusion
The first recorded attempt at blood transfusion, Richard Lower bleeds a dog almost to death and then revives the animal by transfusing blood from another dog via a tied artery at the Royal Society in London, he proves that the idea is feasible. The first successful blood transfusion to a human is achieved in Paris by Jean Baptiste Denis, when a lamb's blood is used to apparently save the life of a 15-year-old boy image:http://www.newscientist.com/blogs/culturelab/2011/03 -
The first modern thermometer
Gabriel Fahrenheit invented the first mercury thermometer, the modern thermometer. Thermometers give us a way to quantify or put a number on the temperature of anything that may be affected by heat, including ourselves. The human body only functions well over a very narrow temperature range. Thermometers allow us to determine quickly if a person is in a normal state or a dangerous state. image: http://www.dailymail.co.uk/news/article-2194635 -

The hypodermic syringe with a plunger is developed
Forms of intravenous injection and infusion began as early as 1670. However, Charles Gabriel Pravaz (France) and Alexander Wood (Scotland) were the first to develop a syringe with a needle fine enough to pierce the skin. Many of the technical difficulties which had faced those experimenting with blood transfusion were removed after 1853 by the invention of the hypodermic syringe, with its hollow pointed needle.
