A medical fluid infusing device (400) acquires image pickup order data from an RIS (100) through a data input section (422) before medical fluid infusion is started. On the basis of personal condition data in the acquired image pickup order data, a confirmation judging section (423) judges whether infusion confirmation is necessary or not. If necessary, a warning section (424) outputs a confirmation warning. Therefore, for example, if the subject is allergic to medical fluids such as the contrast agent, a confirmation warning is automatically outputted before the medical fluid infusion is started. With this, a medical fluid infusing device having a structure simply and reliably enabling prevention of infusion of a medical fluid inappropriate to an allergic subject is provided.
