ABSTRACT:
A hypodermic cartridge includes a barrel having a cannula attached to a forward end thereof. The rear or inner end of the cannula extends into the barrel interior and is provided with a deflected or bent section having its distal portion juxtaposed the peripheral wall of the barrel. In use, upon aspiration, the first droplet of blood is readily viewable through the barrel wall regardless of whether the medicament contained in the barrel is clear, translucent or opaque.
