ABSTRACT:
A blood collecting valve (10) is provided with a structural input part (11.1) with a half moon shaped separating wall opening (18) as well as a structural output part (12.1) which is rotatable with respect to the structural input part with a seal face opening (23). Both are disposed outside of the rotational axis of the associated structural parts. Thereby, it is possible to bring the two opening into congruence with each other by rotating around the rotational axis or to again sealingly separate the same from each other.
The mentioned common rotating of the structural input part and the structural output part and thereby the opening and closing of the blood collection valve may be performed by rotating a blood collecting cylinder (16) being inserted into the structural output part with an application conus (15). Hence, no separate manual handling is required for using the blood collection valve.
