Popis:	In this paper, we designed an artificial blood-circulation system and an original medical device for the improvement of blood flow. First, we prepared an electromagnetic flowmeter and an adaptable coil conformed to the imitative system. The sinusoidal and rectangular signals emitted were sampled with a differential amplifier. Under a constant liquid-flow rate of 7.5 L/min at the alternating electromagnetic field strength of 20 mT, we were able to obtain an induced electromotive force of approximately 2.8 mV. In addition, we investigated the potential of some frequency-changing items to act as a new life-support device for clinical applications. By modifying a commercial magnetic field machine, we designed a prototype equipped with frequency switching of 50 and 0.5 Hz to trial a cure for poor lower limb intravenous flow, lower limb edema, and venous thrombus formation. These systems may provide new knowledge about a mechanism of blood massotherapy by electromagnetic stimulations in the developments of alternating magnetic field machines.
