Abstract: The current invention refers to a system that can be used either together or separately for the heating monitoring the temperature of parentheral solutions used in medical exams, clinical and surgical treatments, etc. The system consists of a Heating Bag (15) and a Protracted Thermal Bag (18), which envelops both the individual container of parenteral solution and the IV. The heating process is done by the Resistors (22 and 23), which are controlled by a Central control unit (30), as well as by a Thermal Box (01) controlled by a Central control unit (04), the heating being done by the Resistor (05). The temperature Sensor (12) allows the monitoring of the internal temperature in order to heat up and preserve the temperature of the parenteral solutions used in human and veterinarian treatment.
