Patent ID: 7270636

Claim:
An apparatus for pulse detection, based on blood pressure measuring stage, comprising: an inflatable cuff connected to a pressure sensor and applied to a subject's body part; an air pump connected to the inflatable cuff and providing an applied pressure of the inflatable cuff via an inflation, wherein the pressure sensor detects a signal of pressure variation in response to the applied pressure; a signal processor module electrically connected to the pressure sensor, receiving the signal of pressure variation and subsequent analyzing the signal of pressure variation to acquire a pressure signal and a resonance signal; a CPU electrically connected to the signal processor module, receiving the pressure signal and the resonance signal and calculating a blood pressure parameter of the subject; a pressure relief valve connected to the inflatable cuff for reducing the pressure therein in accordance with a predetermined pressure, wherein a unique sequential pressure control of reduction and regulation of pressure is executed on the inflatable cuff, a reduction pressure signal is detected by the pressure sensor, the reduction pressure signal is analyzed by the signal processor module, the analyzed reduction pressure signal is delivered to the CPU to acquire at least one pulse signal and at least one pulse parameter of the subject; and a display unit connected to the CPU displaying the blood pressure parameters and the pulse parameters, wherein the pulse parameter comprises at least one of a vascular stiffness index and a vascular reflection intensity.
