1. A blood collection device comprising:
- a housing having a first curved sidewall with an outwardly curved first finger hold on a proximal end of the first curved sidewall and a second curved sidewall with a outwardly curved second finger hold on a proximal end of the second curved sidewall, the first curved sidewall and the second curved sidewall defining an annular holding chamber to secure an umbilical cord without cutting or severing the umbilical cord;
a hinging member pivotally connecting said first sidewall to said second sidewall;
a needle shield disposed at an angle relative to the housing, a retractable needle mounted inside the needle shield, a luer port at the proximal end of the needle shield;
a plurality of first grasping fingers disposed on the distal end of the first sidewall, the first sidewall is inwardly curved and the plurality of first grasping fingers having a plurality of small protuberances;
a plurality of second grasping fingers disposed on the distal end of the second sidewall, the plurality of first grasping fingers orientated in a reciprocating configuration with the plurality of second grasping fingers, the second sidewall is inwardly curved and the plurality of second grasping fingers having a plurality of small protuberances, the plurality of first grasping fingers having a cut away section to receive and reciprocally engage the plurality of second grasping fingers when in a closed position, the plurality of first grasping fingers and plurality of second grasping fingers disposed below the needle shield, the first finger hold being shorter in length than the plurality of first grasping fingers and the second finger hold being shorter in length than the plurality of second grasping fingers;
a cavity formed between the plurality of first grasping fingers and the plurality of second grasping fingers when in a closed position.
