Abstract: A disposable syringe incapable of re-use comprising a plunger itself comprising an elongated stem, a disk called a “spider” held near the lower end of the stem. The plunger furthermore comprises a stem extension in the shape of a short cylinder, affixed to the lower face of the spider. Finally the plunger comprises a handle affixed to the upper end of the stem. In addition, the syringe comprises a lower seal and upper seal both of cylindrical annular shape made of rubbery material, having their external cylindrical surface forming an air-tight fit with the inner wall of the barrel. The internal cylindrical surface of the lower seal forms a liquid-tight slip fit with the stem extension. The upper seal's internal diameter is larger than the stem thus forming a gap between itself and the stem, this gap allowing fluid to circulate freely. In addition, the upper seal forms an air-tight combination with the spider when they are in contact.
