Abstract
The disclosure relates to a mixing machine, system, and method including: a measurement device able to measure a volume of a biological fluid; a pumping device able to pump an anticoagulant and/or preservation solution into the biological fluid; and a control system for the pumping device. The control system may include: a device for determining an actual volume of the solution previously pumped by the pumping device and an automatic control able to control a pumping speed of the pumping device. The automatic control may control the pumping speed by calculating a theoretical volume of the solution to be mixed with the biological fluid previously pumped by the pumping device as a function of a determined ratio of the biological fluid collected and the solution pumped; comparing the theoretical volume to the actual volume; and adjusting the pumping speed of the pumping device to approach the determined ratio.
