Abstract

An electronic sphygmomanometer includes a cuff to be attached to a blood pressure measurement site, a pump and a valve for adjusting a pressure to apply on the cuff, a pressure sensor for detecting the pressure of the cuff, a central processing unit (CPU) for calculating a blood pressure value from the cuff pressure, a memory for recording the blood pressure value, and an operation unit for performing a blood pressure measurement. Further, the CPU acquires information on an application voltage of the valve or the pump at a time of blood pressure measurement, and the information on the application voltage is stored in the memory. The CPU corrects the application voltage so that control of the valve or the pump is carried out based on the application voltage stored in the memory.

Claims

1. An electronic sphygmomanometer comprising:

a cuff to be attached to a blood pressure measurement site;

pressurization and depressurization means for adjusting a pressure to apply on the cuff;

pressure detection means for detecting the pressure of the cuff;

blood pressure calculation means for calculating a blood pressure value from the cuff pressure;

recording means for recording the blood pressure value;

operation means for performing a blood pressure measurement;

input means for inputting user information;

information acquiring means for acquiring information on an application voltage of a valve or a pump at a time of blood pressure measurement,

wherein the recording means stores the information on the application voltage of the valve or the pump at the time of blood pressure measurement in association with the user information when the information on the application voltage of the valve or the pump at the time of blood pressure measurement is acquired by the information acquiring means; and

correction means for correcting the application voltage so that control of the valve or the pump is carried out based on an application voltage in a case where the application voltage associated with the user information is stored in the recording means when calculating the blood pressure with the blood pressure calculating means.

2. The electronic sphygmomanometer according to claim 1, wherein the recording means stores the application voltage of the valve or the pump at the time of the blood pressure measurement in association with the cuff pressure corresponding to each application voltage.

3. The electronic sphygmomanometer according to claim 1, wherein the recording means stores the application voltage of the valve or the pump at the time of the blood pressure measurement in association with an elapsed time in which the application voltage is applied.

4. The electronic sphygmomanometer according to claim 1,

wherein the recording means stores the application voltage of the valve or the pump at the time of the blood pressure measurement in association with user information related to a peripheral length of a measurement site or a quality of a measurement site, and

wherein in a case where the user information differs from that stored in the recording means in a measurement for this time, the correction means corrects the application voltage based on the user information, and overwrites the application voltage with the corrected application voltage to store in the recording means.

5. A blood pressure measurement method for adjusting a pressure to apply on a cuff attached to a blood pressure measurement site with pressurization and depressurization means, and calculating a blood pressure value with blood pressure calculation means based on a cuff pressure detected by pressure detection means;

the blood pressure measurement method comprising the steps of;

accepting input of user information by input means;

acquiring information on an application voltage of a valve or a pump at a time of blood pressure measurement with information acquiring means;

storing the information on the application voltage of the valve or the pump at the time of blood pressure measurement in recording means in association with the user information when the information on the application voltage of the valve or the pump at the time of blood pressure measurement is acquired by the information acquiring means; and

correcting by correction means the application voltage so that control of the valve or the pump is carried out based on an application voltage in a case where the information on the application voltage associated with the user information is stored in the recording means when calculating the blood pressure with the blood pressure calculating means.

6. The blood pressure measurement method according to claim 5, wherein the step of correcting by the correction means comprises storing the application voltage of the valve or the pump at the time of the blood pressure measurement in the recording means in association with the cuff pressure corresponding to each application voltage.

7. The blood pressure measurement method according to claim 5, wherein the step of correcting by the correction means comprises storing the application voltage of the valve or the pump at the time of the blood pressure measurement in the recording means in association with an elapsed time in which the application voltage is applied.

8. The blood pressure measurement method according to claim 5,

wherein the step of correcting by the correction means comprises:

storing the application voltage of the valve or the pump at the time of the blood pressure measurement in association with user information related to a peripheral length of a measurement site or a quality of a measurement site; and

correcting the application voltage based on the user information in a case where the user information differs from that stored in the recording means in a measurement for this time, and overwriting the user information with the corrected information of the application voltage to store in the recording means.
