Abstract

DISPOSITIVO DE SERINGA TENDO SISTEMA DE VENTILAçãO. A presente invenção refere-se a um dispositivo de seringa que inclui um tubo de seringa tendo uma extremidade distal com uma passagem em comunicação de fluido com uma cavidade do mesmo. Uma haste de êmbolo se encaixa deslizável e vedavelmente dentro da cavidade do tubo de seringa. A haste de êmbolo inclui pelo menos uma abertura em comunicação de fluido com um interior oco da haste de êmbolo. Uma ponta de êmbolo é encaixada com uma extremidade distal da haste de êmbolo e interage com uma superfície interna da parede lateral do tubo de seringa para separar a cavidade em primeira e segunda áreas. Pelo menos uma abertura conecta fluidicamente o interior oco da haste de êmbolo e a primeira área da cavidade de tubo de seringa, de modo que o interior de haste de êmbolo geralmente oco permite que ar se mova entre um exterior do dispositivo de seringa e a primeira área da cavidade durante movimento deslizante da haste de êmbolo dentro do tubo de seringa.
