Abstract

An apparatus for extracting blood fluids from a placenta and umbilical cord comprises a frame assembly, a rotary carriage mounted to the frame assembly for rotation about a vertical axis, a drive operatively connected to the carriage for rotating the carriage about the axis, and a support for holding the placenta and the umbilical cord. A connector pivotably connects the support to the carriage to enable a pivoting of the support about a rotating horizontal axis during rotating of the carriage by the drive, while a collector is attached to the support for enabling a collection of fluid flowing from the placenta and the umbilical cord during operation of the drive. A fluid delivery system is provided for automatically supplying an anticoagulant to extracted blood fluid.

8. The apparatus recited in claim 1, further comprising supply means operatively connected to said support means for supplying an anticoagulant to blood fluid flowing into said collector means.

9. The apparatus recited in claim 8 wherein said supply means includes storage means for storing a supply of said anticoagulant and delivery means for delivering an amount of said anticoagulant to blood fluid flowing into said collector means.

10. The apparatus recited in claim 9 wherein said delivery means includes means for measuring out a predetermined aliquot of said anticoagulant.

11. The apparatus recited in claim 9 wherein said delivery means includes pumping means for pumping said anticoagulant from said storage means.

12. The apparatus recited in claim 9 wherein said storage means is disposed on said support means.

13. The apparatus recited in claim 9 wherein said storage means is disposed on said frame assembly and said delivery means includes a conduit extending through said connector means.

14. The apparatus recited in claim 1, further comprising cleaning means operatively connected to said support means for enabling a cleaning thereof.

15. The apparatus recited in claim 14 wherein said cleaning means includes means for dispensing a cleaning fluid into a chamber in said support means which receives said placenta.

16. The apparatus recited in claim 15 wherein said means for dispensing includes a conduit system extending from said frame assembly, through said carriage and said connector means, and into said support means.

17. The apparatus recited in claim 14 wherein an umbilical cord is attached to said placenta, said support means including a pipe receiving said umbilical cord, said cleaning means includes means for dispensing a cleaning fluid into said pipe.

18. The apparatus recited in claim 17 wherein said means for dispensing includes openings in said pipe.

19. The apparatus recited in claim 1 wherein said support means includes a removable lid assembly, further comprising cleaning means removably mountable to said support means for cleaning same.

20. The apparatus recited in claim 19 wherein said lid assembly is connected to said support means via a telescoping member.

21. The apparatus recited in claim 1 wherein said collector means includes connection means for releasably securing a receptacle to said support means.

22. The apparatus recited in claim 21 wherein said receptacle takes the form of a vial or ampule.

23. An apparatus for subjecting an object to a centrifuging operation, comprising:

a frame assembly;

a rotary carriage mounted to said frame assembly for rotation about a vertical axis;

drive means operatively connected to said carriage for rotating same about said axis;

support means for holding the object; and

connector means for pivotably connecting said support means to said carriage to enable a pivoting of said support means about a rotating horizontal axis during rotating of said carriage by said drive means.

24. The apparatus recited in claim 23, further comprising collector means attached to said support means for enabling a collection of fluid flowing from said object during operation of said drive means.

25. The apparatus recited in claim 24 wherein said collector means includes connection means for releasably securing a receptacle to said support means.

26. The apparatus recited in claim 25 wherein said receptacle takes the form of a vial or ampule.

27. The apparatus recited in claim 23 wherein said object includes an elongate component and said support means includes an elongate tubular member for receiving said elongate component.

28. An apparatus for subjecting a body to a rotary motion, comprising:

a frame assembly;

a rotary carriage mounted to said frame assembly for rotation about an axis, said carriage including a receptacle portion defining a chamber for receiving said body, said carriage further including a cover member removably mounted to said receptacle portion;
