Automatic collection of bovine blood samples

Abstract

n Tegniek vir die outomatiese van nekaarbloed van koeie wat vasgemaak is, word beskryf. In hierdie stelsel word bloed aanhoudend deur n cannula met n dubbel opening gepomp terwyl n antikoagulant deur die tweede opening toegevoeg word. Verdunde bloed word versamel in n fraksieversamelaar wat aan n tydskakelaar gekoppel is.

SUMMARY

A technique is described which allows automatic collection of jugular venous blood from tethered cows. In this system, blood is pumped continuously from an intravenous cannula which has a double lumen while an anticoagulant is pumped through the second opening. Diluted blood is collected in a fraction collector which is fitted with a time-switch.
