ABSTRACT:
An improved blood-taking device of the type wherein a hypodermic needle is inserted into a blood vessel and one or more evacuated containers in succession are connected to the needle for collecting blood samples comprises a support portion which supports the needle and a container portion including a projecting tube, the tip of which can be joined to the support portion in a combined axial and rotational movement. The container portion includes a valve which can be opened in a continuation of the rotational movement used for joining the tube to the support portion. The structure of the components is such that the valve in the container portion is opened only after the container is joined to the support portion through the tube. Similarly, when the operation of taking blood is complete the tube and container portion are separated from the support portion by a rotation in the opposite direction, the structure of the device being such that the valve is closed before the tube is separated from the support portion.
