Patent Images
1. An umbilical cord fluid sampling device comprising:
- at least one moveable sampling needle;
a needle housing constructed and arranged to support the at least one moveable sampling needle;
a base housing constructed and arranged to support a portion of the umbilical cord of a patient, at least one of the base housing and the needle housing being moveable between a closed position and an open position in order to insert the umbilical cord therein;
an interior chamber disposed between the needle housing and the base housing;
at least one sampling reservoir supported within a portion of the chamber and in fluid communication with the at least one moveable sampling needle; and
an opening disposed through at least one of the base and needle housing and in fluid communication with the sampling reservoir, the opening being configured and dimensioned to receive the removable cassette such that a fluid sample may be removed from the sampling reservoir while the base and needle housing remain in the closed position.

14. A method for determining the values of physiologically relevant parameters of a biological fluid, comprising the steps of:
-
providing an umbilical cord sampling device having at least one moveable sampling needle operatively connected to at least one sampling reservoir;
placing an umbilical cord segment in the umbilical cord sampling device;
penetrating a fluid-containing lumen of the umbilical cord segment with a moveable sampling needle;
collecting the fluid in a sampling reservoir; and
removing the collected fluid from the sampling reservoir for analysis. - View Dependent Claims (15, 16, 17)
