Abstract

A novel blood collection device is described to secure a needle in place in a placenta or umbilical cord to prevent needle stick before, during, and after cord blood collection procedure.

Claims

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.

2. The blood collection device of claim 1, further comprising a needle access port for collecting a sample.

3. The blood collection device of claim 2 wherein the needle access point is a connector port.

4. The blood collection device of claim 3, wherein the retractable needle is inserted into the connector port to access a placenta or umbilical cord.

5. The blood collection device of claim 4, wherein the retractable needle further comprises a reuse prevention element.

6. The blood collection device of claim 1 wherein the hinging member is a fixed hinge.

7. The blood collection device of claim 3, wherein the connector port is disposed at an angle relative to the housing.

8. The blood collection device of claim 3, further comprising a syringe having a slidable needle shield inserted into the needle access point to access a placenta or umbilical cord.

9. The blood collection device of claim 1 further comprising an integral clamp disposed in the housing to secure an umbilical cord into place.

10. The blood collection device of claim 1 further comprising a clamp disposed downstream from the needle access point to prevent blood loss from an umbilical cord.

11. The blood collection device of claim 1 further comprising a spring operatively associated with said hinging member for exerting a continual force about said hinging member whereby said first sidewall and second sidewall are urged to a closed position.

12. The blood collection device of claim 2, further comprising a blood access device or evacuated tube connected to the needle access point.

13. The blood collection device of claim 2, wherein the needle access point is adapted to accept a needle with its own integral safety element.

14. A blood collection device comprising:

a housing to secure an umbilical cord having a first inwardly curved sidewall with a first outwardly curved finger hold on a proximal end of the first curved sidewall and a second inwardly curved sidewall with a second outwardly curved 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 for pivotally securing said first sidewall to said second sidewall;

an retractable needle disposed inside a needle shield, the needle shield being integrally connected to a needle access port to access the contents of the needle, the needle shield being disposed at an angle relative to the housing;

a spring operatively associated with said hinging member for exerting a continual force about said hinging member whereby said first sidewall and second sidewall are urged to a closed position, the spring enclosed within the hinging member such that the umbilical cord does not contact the spring;

a plurality of first grasping fingers disposed on the distal end of the first sidewall, 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 second grasping fingers having a plurality of small protuberances, the plurality of first grasping fingers orientated in a reciprocating configuration with the plurality of second grasping fingers, the plurality of first grasping fingers reciprocally engage the plurality of second grasping fingers when in a closed position; and

a cavity formed between the first grasping finger and the second grasping finger when in a closed position.

15. The blood collection device of claim 14 wherein the hinging member is a fixed hinge.

16. The blood collection device of claim 14 further comprising an integral clamp disposed in the housing to secure an umbilical cord into place.

17. The blood collection device of claim 14 further comprising a clamp disposed downstream from the integrated needle to prevent blood loss from an umbilical cord.

18. The blood collection device of claim 14, further comprising a blood access device or evacuated tube connected to the needle via a needle access point.
