<P>PROBLEM TO BE SOLVED: To provide a method for controlling a transfusion device preventing the occurrence of an abnormal stop of transfusion due to welding of a stop switch. <P>SOLUTION: A transfusion device is actuated by a motor and sends out liquid by pressing a plunger of a syringe. The transfusion device is provided with a transfusion start/stop switch using a normally-opened contact and a contact returning common switch. When starting transfusion, start recognition is carried out on the condition that three switch contact signals are generated in the order of an open signal, a short signal and an open signal. When stopping transfusion, stop recognition is carried out on the condition that two switch contact signals are generated in the order of an open signal and a short signal at an arbitrary time. <P>COPYRIGHT: (C)2007,JPO&INPIT |
