An information acquisition device 10 includes a data acquisition unit 11 acquiring measurement data from an external measuring device 20; a code reading unit 12 reading a code to acquire the information represented by the code; and a data processing unit 13 that associates the information acquired by the code reading unit 12 with the measurement data acquired by the data acquisition unit 11. Medical measuring devices used to measure patient status can be suggested as the measuring device 20. In such a case, for example, codes representing identifiers that identify patients can be used as the code.
