Abstract

The present inventionrelates to a small-scale centrifugal blood pump. In particular, the present inventionrelate to a hand-carried portable centrifugal blood pump for emergency use, which may be powered by batteries. The present invention provides a device, for which no cooling system is necessary, hence reducing the energy consumption and the weight of the pump.
