Device for monitoring pulse waveform and measuring blood pressure simultaneously

Abstract

The invention discloses a device for monitoring pulse waveform and measuring blood pressure simultaneously, and belongs to the technical field of medical equipment. A pulse wave module detects brachial arterial pulse fluctuations through a pressure sensor, and signals are transmitted to an analog signal conditioning circuit, an A/D conversion circuit, a single chip microcomputer, an accessory circuit of the single chip microcomputer and an interface circuit between the single chip microcomputer and a PC. Collected data are transmitted to the computer through signals. Meanwhile, blood pressure is measured through inflation and deflation of an inflatable oversleeve, and the data are transmitted to the computer. Finally, the computer collects the pulse waveforms of the pulse wave module, and meanwhile the waveform sampling frequency, the amplification factor and the base line position are adjusted during sampling setting, high pressure, low pressure and the heart rate of a voltage module are received, and the real-time detection function is achieved. According to the device, the obtained pulse waveform data and blood pressure value lay the foundation of calculation of the average blood flow volume, the cardiac output and the like and finally achievement of early prediction of some hemodynamic diseases and the clinical diagnostic function.

Description

technical field [0001] The invention belongs to the field of test verification of medical devices, and relates to a signal processing device, in particular to a device for simultaneously monitoring pulse wave waveform and blood pressure measurement. Background technique [0002] Cardiovascular disease (CVD) is an important disease with the highest mortality rate in developed countries today, and it is also the disease with the highest mortality rate in my country. The World Health Organization has listed it as the number one killer of human health in the 21st century. , it has become a major public health problem in China and the world. It seriously affects people's health and quality of life. Therefore, the early prediction and mid-term diagnosis and treatment of cardiovascular disease are of great significance. [0003] The arterial pulse wave is produced by the periodic contraction and relaxation of the heart, so the pulse wave is a natural "information source". Studies ...
