Embodiment 1
[0073] This embodiment provides a blood pressure measurement method based on Korotkoff sounds. Different from the prior art, this measurement method uses a sensor to detect the pressure pulse signal at the radial artery, and the traditional human ear "listens" to the Korotkoff sound. The method is changed to directly measure the Korotkoff sound. At the same time, it is different from the measurement method of the electronic Korotkoff sound sphygmomanometer, and the accuracy of this measurement method is higher. This method comprises the following steps:
[0074] After wearing the cuff, the subject starts to inflate and pressurize the cuff airbag at the brachial artery. At the same time, detect the fluid pressure pulse wave signal at the radial artery in real time, and the detected pulse wave signal is displayed on the display after processing. form a waveform.
[0075] During the cuff inflation process, the blood vessels at the brachial artery are gradually squeezed until the...
Embodiment 2
[0084] Such as Figure 6 As shown, this embodiment provides an intelligent blood pressure measurement device based on Korotkoff sounds, including a cuff and a measurement host. In this embodiment, the cuff adopts a national standard cuff structure, which is simple in structure, single tube and single air bag, and is suitable for standardized cuff. The measurement host includes: a central processing module, a display screen, an intelligent pressurization module, an intelligent pressure relief module, a waveform display module, a pulse signal acquisition module, a cuff airbag pressure acquisition module, a cardiovascular parameter calculation module and a communication module, and the power supply adopts an external power supply or batteries.
[0085] The central processing module is mainly responsible for the data processing of each acquisition signal, such as: pulse wave waveform, systolic blood pressure, diastolic blood pressure, etc., and the model STM32F103ZET6 is selected...
