    Abstract: The present invention provides a carotid blood pressure detection device, comprising: a first sensing unit, a second sensing unit, and a controller connected or coupled to the first sensing unit and the second sensing unit. The first sensing unit is disposed on a subject's neck and adjacent to a first position of the subject's carotid arteries. The second sensing unit is disposed on the subject's neck and adjacent to a second position of the subject's carotid arteries. The controller derives a mean arterial pressure of a section of the subject's carotid arteries that lies between the first position and the second position of the subject's carotid arteries from pulse wave data measured and obtained by the first sensing unit and pulse wave data measured and obtained by the second sensing unit.

    Abstract: A high-precision vortex flow meter includes a blunt body having a predetermined dimension and being arranged inside a fluid channel to serve as a vortex shedder. The vortex flow meter also includes a temperature detecting device for detecting the vortex shedder temperature and a temperature control element for adjusting the vortex shedder temperature. A frequency measuring device is arranged in the downstream section of the blunt body for detecting the vortex shedding frequency. From the measured temperatures of the upstream fluid flow and that of the blunt body, an effective temperature and a temperature ratio are calculated. The kinematic viscosity of the fluid is looked up from database. By using the relationship between the Strouhal number and Reynolds number, the fluid flow rate is calculated. By employing different blunt body temperature, the measurement range of the flow meter can be broadly extended.

    Abstract: A method for detecting heart rhythm irregularities, including the steps of: measuring pulse peaks continuously over a period of time to obtain pulse peak sequence and pulse peak time interval sequence corresponding to the pulse peak sequence; and calculating the absolute value of a difference between a single pulse peak time interval in the pulse peak time interval sequence and an average value of the pulse peak time interval sequence, and determining that an irregular pulse peak (IPP) has occurred if the absolute value is larger than or equal to 15% to 25% of the average value of the pulse peak time interval sequence. A detection device using the method is also provided. This uses a non-invasive approach to detect heart rhythm irregularities such as sick sinus syndrome, irregular pulse peaks, irregular heartbeat, and atrial fibrillation, and can be applied to a sphygmomanometer or a wearable device.

    Abstract: A single-arm micro air-pressure pump device, having an air pump body and a driving unit. The air pump body includes a supporting frame, an air chamber unit coupled to a side of the supporting frame, and a swing arm provided on the air chamber unit. The driving unit is fixed on the supporting frame and has an output shaft. The output shaft is provided with an eccentric shaft and is configured to rotate the eccentric shaft, and the eccentric shaft has an end coupled to the output shaft and an opposite end coupled to the swing arm in order to drive the swing arm into a reciprocating motion between at least a proximal position and a distal position with respect to the air chamber unit. The reciprocating motion pushes a piston unit provided on one end of the swing arm and causes the air output.
