| Outline of Final Research Achievements |
Aims of this research are 1) To develop a cuffless sphygmomanometer and evaluate the device with static accuracy and long-term stability. 2) To propose a new standard of cuffless sphygmomanometer and 3) To discuss a suitable protocol to evaluate the cuffless sphygmomanometer. The results of this research show 1) developed cuffless sphygmomanometer had a good accuracy within 5±8 mmHg which is enough accuracy of cuff-based sphygmomanometer. 2) We proposed a standard of cuffless sphygmomanometer to ISO.TC121/S3/JWG7, but the proposal was rejected. 3) to discuss the regulatory authority of PMDA, the protocol of cuffless sphygmomanometer was good and the obtained accuracy, is acceptable, but the that of long-term stability continuously needed to improved.
In conclusion, the cuffless sphygmomanometer may use as an alternative blood pressure monitor and the accuracy, stability and reliability tests are required to approve as medical device.
