Hypodermic device
First Claim
1. A device for extracting blood comprising:
- a main body having a plurality of sockets with each socket having a needle therein with the longitudinal axis of each of the needles being substantially parallel to the longitudinal axis of each respective socket;
an axially movable plug coaxially mounted within each socket adjacent an end of each needle;
means interconnecting each of said needles to a main passage through said body;
a hypodermic needle connected to said main passage; and
one or more tubes, each having a sealed end with a predetermined amount of vacuum therein with each tube being operatively inserted into a selected socket for piercing the sealed end of the tube with a needle end and with the movable plug being axially displaced by the movement of the tube within the socket.

Abstract
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.

3. A device for extracting blood comprising:
-
a main body having a plurality of sockets with each socket having a needle therein with the longitudinal axis of each of said needles being substantially parallel to the longitudinal axis of each respective socket; means interconnecting each of said needles to a main passage through said body, said interconnecting means comprising a movable plug within each socket having a passage therein which is selectively movable into coaxial alignment with the main passage and each needle connected to a respective plug passage; a hypodermic needle connected to said main passage; and one or more tubes each having a sealed end with a predetermined amount of vacuum therein and each tube being operatively inserted into a selected socket with the sealed end of the tube being pierced by a respective needle within the socket thereby permitting fluid communication between said hypodermic needle and the tube.
