ABSTRACT:
A cradle for use in blood donating processes comprises surface (2) which is intended to support a blood-collecting bag and to be rocked reciprocatingly on an axle (4) which extends perpendicularly to the surface, by means of a crank (5, 7). The cradle is provided with a weight measuring device (8) which functions to measure the quantity of blood that has flowed into the bag, and is also fitted with a clamping device (11) which functions to clamp-on or squeeze the hose such as to prevent blood from flowing therein and which is operable electromagnetically. The cradle is further provided with a control circuit (21) which is constructed to control at least the clamping device (11). The cradle is characterized in that the control circuit (21) is constructed so that, upon receipt of a given signal from the operator, it will cause the clamping device (11) to clamp-on the hose, and will cause the clamping device (11) to release the hose in response to a given start signal from the operator; and in that the control circuit (21 ) is constructed to cause the clamping device to alternately clamp-on the hose and release the hose in a manner such as to release a small quantity of blood at a time when a given, predetermined amount of blood remains to be taken from the donor; and in that the control circuit is constructed in a known manner to cause the clamping device to clamp-on the hose when a predetermined amount of blood has flowed into the blood bag.
