A medical measurement system, comprising:

• a medical measurement device that acquires information about a subject body;
• and
• an external device,
• wherein the measurement device includes:
• a measurement portion that acquires measurement data obtained by measurement;
• a setting portion that specifies an external device as a transmission destination of the measurement data based on a signal transmitted from the external device, and records information of the specified external device, thereby allowing communication with the external device without receiving input of authentication information;
• and
• a transmission and reception portion that transmits the measurement data to the external device specified by the setting portion and receives data from the external device, and
• the external device includes:
• a measurement device determination portion that specifies a measurement device as a transmission source of the measurement data based on a signal from the measurement device, and allows communication with the measurement device without receiving input of authentication information;
• and
• a reception portion that receives the measurement data from the specified measurement device,
• the setting portion of the measurement device causing the transmission and reception portion to transmit identification information of the measurement device for enabling mutual communication with respect to the external device as a transmission source of the received signal, and further to transmit or receive confirmation information that is used for a decision of whether or not the measurement data transmitted from the measurement device is to be handled between the measurement device and the external device.
