Blood collection tube |
| abstract |
A blood collection tube for physically separating the plasma and red blood cell fractions of a centrifuged sample is described. The blood collection tube has an elastomeric sleeve with rigid tube segments at both ends. Following blood collection and centrifugation, the elastomeric sleeve may be twisted to constrict its inner diameter and physically separate the two fractions. The blood collection tube may be secured in this position with a pin and a clamp, and further with an adhesive tape with pH paper. This enables blood samples to be transferred over long distances to a central lab facility without spoiling. |
