  • Patent number: 7597667
    Abstract: A method for judging irregular heartbeat performs a measurement step to measure a plurality of heartbeat pulses within a time period for a user, and to measure inter-pulse durations and total pulse numbers. The method further performs a calculation step to calculate an averaged inter-pulse duration and a heartbeat number. Afterward, the method performs a first-stage judgment step to judge whether the measured pulse number is sufficient. When the first-stage judgment step is matched, a second-stage judgment step is performed. The second-stage judgment step judges irregular heartbeat condition by comparing the averaged inter-pulse duration with each inter-pulse duration. Finally, this method performs a display step to show a sign of irregular heartbeat when the irregular heartbeat condition is matched. This method can solve inaccuracy problem due to preset threshold.

  • Patent number: 7204809
    Abstract: A pressurizing apparatus and method for adjusting an optimal pressurizing rate according to a cuff of various lengths. The pressurizing method measures the pressure values at two reference points and time duration to calculate a pressurizing rate. A control adjustment routine to control an adjustment of the pressurizing rate is decided according the calculated pressurizing rate and at least one control condition. The pump is pressurized according to the adjustment of the pressurizing rate. A diastolic pressure value is measured and the pressurizing of the pump is kept to measure a systolic pressure value. Afterward, the pressurizing is stopped to prevent uncomfortable feeling of user caused by rapidly pressurizing and de-pressurizing process.
