Sleeveless blood pressure measuring device and measuring method based on finger pressure oscillography

Abstract

The invention discloses a sleeveless blood pressure measuring device based on finger pressure oscillography. The device is characterized in that the device comprises a signal acquisition unit and a communication and calculation unit which are electrically connected, wherein a photoelectric pulse wave acquisition module and a pressure signal acquisition module are arranged on the signal acquisitionunit; a main controller and a USB serial port communication module connected with the main controller are arranged on the communication and calculation unit; the USB serial port communication moduleis connected with a display module; the photoelectric pulse wave acquisition module comprises a reflective photoelectric pulse wave sensor and a pulse wave signal preprocessing module which are sequentially connected; the pressure signal acquisition module comprises a pressure signal sensor and a processed pressure signal module which are sequentially connected; and the outputs of the pulse wave signal preprocessing module and the processed pressure signal module are both connected with the main controller. The device needs less input signals, the relationship between input signals and blood pressure levels is stable, so that the device is easy to operate and low in cost. This method is simple to operate, easy to master and practical.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to a cuffless blood pressure measuring device and a measuring method based on finger pressure oscillometric method. Background technique [0002] Blood pressure is one of the important physiological indicators for human health evaluation. In recent years, with the rapid development of my country's economy, people's diet structure and work and rest patterns have changed. The number of hypertensive patients in my country is constantly increasing, and various complications caused by hypertension have become common diseases. At this stage, the number of people suffering from cardiovascular disease and the resulting death toll in our country are still in the stage of continuous growth. Human blood pressure measurement is becoming more and more urgent in clinical disease diagnosis and home intelligent health monitoring. The mature blood pressure measuring equipment currently on the mark...
