Simulation Model of the Control System of Portable Boxes for Blood Bags Transport

Blood transport is very important in the healthcare sector; new technologies can help implement efficient transport systems. To maintain unaltered the bio-chemical properties of blood during transports, blood bags need to be kept within a precise temperature range for the entire travel time. This paper presents a Matlab-Simulink model of an innovative box for blood transport, including a temperature control system which employs eutectic fluid elements exchanging heat with the transported blood bags. To keep the temperature within the correct range, on-off blowers provide an air flow between the eutectic and blood compartments. The basic idea is to equip the boxes with sensors that dialogue by cloud with a server on which the simulator is installed; this allows to continuously monitor the time remaining before the exhaustion of the eutectic cooling effect, in which case a logistic algorithm will provide the coordinates of the nearest healthcare location for blood deposition.
