Abstract

Provided are a measurement device by which the blood-sugar level or the like associated with the living activity of a diabetic patient can be measured easily and precisely and the measured valued associated with the living activity can be clinically applied easily, and an insulin infusion device, a measurement method, a method for controlling an insulin fusion device, and a program. A blood-sugar level measurement device (100) is provided with a blood-sugar level sensor (200) and an acceleration sensor (112) for measuring movement information associated with human body activity, wherein a CPU (110 controls, on the basis of the measured movement information, whether or not the measurement operation of a blood-sugar measurement circuit (113) can be executed. The CPU (110) further associates and records in a recording unit (111) the measured blood-sugar level and the movement information measured by the acceleration sensor (112), and displays the associated blood-sugar level and movement information on a display unit (102). The CPU (110) further combines the blood-sugar level measured by the blood-sugar level sensor (200) and the data detected by the acceleration sensor (112) and executes each mode processing.

Claims
