Abstract

A blood glucose level measuring apparatus and measurement data management apparatus are provided which can carry out measurement of the blood glucose level of a plurality of patients relatively rapidly and reliably, while also addressing emergency situations. The blood glucose level measuring apparatus includes a patient identifier, blood glucose level measuring device, a date/time counter, a display, and a controller. The controller controls in a normal measurement mode the cross-checking of patient identification information and a patient data table, and then, if patient identification information is not found, measurement of the blood glucose level is inhibited. The controller also controls in an emergency measurement mode in which carrying out of measurement of the blood glucose level is permitted without acquiring the patient identification information by the patient identifier.

4. The blood glucose level measuring apparatus according to claim 1, wherein the control means also effects control during a history mode so that:

in the normal measurement mode, the blood glucose level and the date/time information which are associated with the selected patient identification information are displayed on the display;

but

in the emergency measurement mode, the blood glucose level, the date/time information and the mode information are displayed on the display and, if the identification means acquires the patient identification information, the blood glucose level and the date/time information are recorded into the measurement data table in an associated relationship with the patient identification information.

5. A measurement data management apparatus for managing data of the blood glucose level measuring apparatus according to claim 1, comprising:

host communication means for communicating with the communication means;

a patient history table adapted to record the blood glucose level and the date/time information in an associated relationship with the patient identification information;

a temporary patient measurement file adapted to record one string of transmission data and wherein the patient identification information is blank information; and

host control means for extracting the patient identification information from the one string of transmission data and cross-checking the extracted patient identification information and said patient history table with each other and then;

recording, if the patient identification information is found in the patient history table, the blood glucose level and the date/time information at which the blood glucose level is obtained into the patient history table in an associated relationship with the patient identification information;

but recording, if the patient identification information is not found in the patient history table, the blood glucose level and the information of date/time into the temporary patient measurement file.
