Abstract
A needle free vacuumized blood collection device includes a male connector having a valve element disposed within the internal bore of the male connector that opens or closes a flow passage into the blood collection vial. The valve element includes an activation arm extending outwardly through the male connector that contacts a female connector when the male and female connector are engaged. The activation arm shifts the valve element in the proximal direction to open a naturally open flow opening in the valve element to permit flow into the vial. A spring device biases the valve element to the non-flow configuration.
