Abstract
A collector of a blood sample from a body member comprising a hollow container which is closed at both ends and has a hypodermic needle projecting from one of the ends and extending into the interior of the container. An arcuate disc of a frangible, inert material is sealingly positioned within the container to divide it into two compartments, one containing a blood culturing medium, the other air. An elongated tube engages the interior end of the needle and passes through the disc into the air chamber. When the wall of the container is deflected inwardly to expel the air to create a negative pressure condition within the container, the disc is broken thus allowing the blood drawn into the container when the wall is released to mix with the medium.
