A hypodermic device including a main body having a plurality of open sockets with a corresponding number of upstanding needles therein. In one embodiment, each upstanding needle is commonly interconnected to a main passage through the body. The ends of the upstanding needles are capped with resilient plugs which are displaced when one or more vacuum tubes are pressed onto the ends of the upstanding needles. In an alternative embodiment of the device, the upstanding needles are secured to movable plugs with each plug having a passage therein which is selectively movable into coaxial alignment with the main passage through the body. In yet another embodiment of the device, the sockets are spaced apart along the length of the main body with valves being connected to the main body in the spaces between the sockets. Each valve is slidably movable within a well formed within the body. A passage through each valve is brought into coaxial alignment with the main passage through the body thereby permitting blood to be drawn into one or more of the vacuum tubes.
