Confecção de "bomba à vácuo" para aspiração: simples, barata e eficiente, com Dr Luiz Carvalho

Vacuum pumps are very useful in healthcare, especially in surgical procedures where the aspirated fluid is thicker (saliva, blood, etc.). However, they are expensive pieces of equipment and require very special care in their maintenance and use. My proposal is for you to create a system using a plastic bottle and suction device, in a very inexpensive way.
