Method and apparatus for blood collection

Abstract

Blood collection apparatus includes a blood collection container and a mix detection unit operatively coupled to the blood collection container. The mix detection unit includes a device to produce a data signal indicative of the extent to which the blood collection container is moved in a manner to promote mixing of blood collected into the container and an anti-coagulant also present in the container. A method described herein provides for filling a blood collection container with blood, inverting the blood collection container by hand to mix the blood with an anti-coagulant, and viewing or listening to an indication generated by a mix detection device attached to the blood collection container, wherein the indication provides information about the appropriate amount of mixing for the blood.

We claim: 
     
         1 . Apparatus comprising:
 a blood collection container;   a mix detection unit operatively coupled to the blood collection container; and   the mix detection unit including a device to produce a data signal indicative of the extent to which the blood collection container is moved in a manner to promote mixing of blood collected into the container and an anti-coagulant also present in the container.
