Abstract

A blood pressure meter, a thermometer, and a pulse oximeter are connected to the control apparatus, and the control apparatus includes an input unit configured to wirelessly input information identifying a measurement time and unique information along with the measurement value from the measurement devices, a processing unit configured to store the inputted measurement value and unique information in a memory, and an authentication unit configured to authenticate the measurement device that inputted the measurement value as being the same as a measurement device that inputted a stored measurement value by comparing the unique information with unique information stored along with a measurement value measured prior to the inputted measurement value. Here, the processing unit is configured to store the inputted measurement value in the case where the authentication succeeds.

First claim

The invention claimed is:

1. A wireless, self-authenticating biological information monitoring system comprising:
a first health measurement-type device that is a blood pressure meter including a blood pressure sensor that is configured to measure a first health measurement-type value; and
a second health measurement-type device that measures a different biological characteristic than the blood pressure meter, and is provided separately from the first health measurement-type device, the second health measurement-type device having a unique device identifier that is different from a unique device identifier of the first health measurement-type device, the second health measurement device being configured to:
(i) measure a second health measurement-type value,
(ii) generate a time of measurement of the second health measurement-type value, the time of measurement of the second health measurement-type value being a time when the second health measurement-type value was measured, and
(iii) wirelessly transmit the measured second health measurement-type value, the unique device identifier of the second health measurement-type device and the time of measurement of the second health measurement-type value to the first health measurement-type device;

wherein the first health measurement-type device comprises:
a wireless communication interface that wirelessly communicates with at least the second health measurement-type device,
a memory, and
a processor programmed to:
store, in the memory, the unique device identifier of the first health measurement-type device in association with a unique patient identifier of a measurement subject;
receive, via the wireless communication interface from the second health measurement-type device, a first measurement of the second health measurement-type value, the unique device identifier of the second health measurement-type device, and a time of measurement of the first measurement of the second health measurement-type value;
store the received unique device identifier of the second health measurement-type device in the memory as a provisional device identifier;
receive a measurement of the first health measurement-type value and generate a time of measurement of the measurement of the first health measurement-type value, the time of measurement of the measurement of the first health measurement-type value being a time when the measurement of the first health measurement-type value was measured;
receive, via the wireless communication interface from the second health measurement-type device, a second measurement of the second health measurement-type value, the unique device identifier of the second health measurement-type device that transmitted the second measurement of the second health measurement-type value, and a time of measurement of the second measurement of the second health measurement-type value;
determine whether the second health measurement-type device that transmitted the second measurement of the second health measurement-type value has been previously-used by determining whether the unique device identifier of the second health measurement-type device that transmitted the second measurement of the second health measurement-type value matches the stored provisional device identifier;
successfully authenticate the second health measurement-type device that transmitted the second measurement of the second health measurement-type value as being the same as the previously-used second health measurement-type device when the result of the determination indicates that the unique device identifier of the second health measurement-type device that transmitted the second measurement of the second health measurement-type value matches the stored provisional device identifier; and
when the second health measurement-type device that transmitted the second measurement of the second health measurement-type value has been successfully authenticated, and the time of measurement of the measurement of the first health measurement-type value and the time of measurement of the second measurement of the second health measurement-type value are both measurement times that fall within a predetermined amount of time, associate and store together both the measurement of the first health measurement-type value and the second measurement of the second health measurement-type value as a measurement value group in a predetermined region of the memory.

2. The biological information monitoring system according to claim 1 , wherein the processor is further programmed to:
when the received unique device identifier of the second health measurement-type device that transmitted the second measurement of the second health measurement-type value does not match either the stored provisional device identifier, or a unique device identifier stored in the predetermined region of the memory: (i) determine that authentication has failed, and (ii) output failure information to a display of the first health measurement-type device, the output failure information indicating that the first health measurement-type device has failed to authenticate the second health measurement-type device.

3. The biological information monitoring system according to claim 1 , wherein the processor is further programmed to: when the second health measurement-type device that transmitted the second measurement of the second health measurement-type value has been successfully authenticated, store the associated measurement of the first health measurement-type value and the second measurement of the second health measurement-type value along with the unique device identifier of the first health measurement-type device and the unique device identifier of the second health measurement-type device that transmitted the second measurement of the second health measurement-type value in the predetermined region of the memory on a measurement time-by-measurement time basis.

4. A wireless, self-authenticating biological information monitoring method comprising:
storing in a memory of a first health-measurement type device, by the first health measurement-type device, a unique device identifier of the first health measurement-type device in association with a unique patient identifier of a measurement subject, the first health measurement-type device being a blood pressure meter including blood pressure sensor that is configured to measure a first health measurement-type value;
receive, via a wireless communication interface of the first health measurement-type device, from a second health measurement-type device, a first measurement of a second health measurement-type value, a unique device identifier of the second health measurement-type device, and a time of measurement of the first measurement of the second health measurement-type value, which is a time when the first measurement of the second health measurement-type value was measured, the second health measurement-type value being a different biological characteristic than the first health measurement-type value measured by the blood pressure meter, the second health measurement-type device being provided separately from the first health measurement-type device, the unique device identifier of the second health measurement-type device being different from the unique device identifier of the first health measurement-type device;
storing, by the first health measurement-type device, the received unique device identifier of the second health measurement-type device, in a memory of the first health-measurement type device, as a provisional device identifier;
measuring, by the first health measurement-type device, a measurement of the first health measurement-type value;
generating, by the first health measurement-type device, a time of measurement of the measurement of the first health measurement-type value;
