The syringe

Syringe 
   
The syringe was invented by Charles Gabriel Pravaz.
It was invented on 1841 
It allowed to inject medicines under the skin, as antibiotics, without cuts in the body.
The plastic ones arrived on the sixties and prevented infections.
Manuel Jalón invented the disposable syringe because use the same syringe for different people is dangerous. On the contrary plastic pollutes the environment.
