SAMPLING IN BLOOD COLLECTION

摘要

Methods and apparatus are disclosed whereby the initial flow of blood during blood collection is diverted to a sample pouch to trap the skin plug and to allow samples to be taken during subsequent blood collection to a normal blo od bag. This is effected by connecting the needle line (106), the sample line (118) to the sample pouch (116) and the bag line (114) to the blood bag to a multi-port valve (110) that includes an actuator (120). During the procedure , the valve (110) may be attached to the arm (100) of the donor by means of a wrist-strap (112).
