Embodiment Construction

[0037] Below according to accompanying drawing and embodiment the present invention will be described in further detail:

[0038] In order to obtain both measurement results of the auscultation method and the oscillation method in one measurement, the embodiment of the blood pressure measurement module of the present invention is as follows figure 1As shown, it includes three parts: a measurement module 10 , a cuff 20 with an airway tube, and a sound detection module 30 . Wherein the measurement module 10 includes: an inflation and deflation control module 11, a pressure detection module 12, a pressure processing module 14, a sound processing module 15, an AD conversion module 16, a control module CPU18, and a display device 17 can also be added in practical applications to display measurement result. The inflation and deflation control module is used to accept CPU instructions and control the cuff to automatically inflate or deflate according to the CPU instructions. The pre...

Abstract

The invention relates to a blood pressure measuring module and a blood pressure measuring method. The measuring module comprises a cuff, a charging and discharging control module, a pressure detectionmodule, a pressure processing module, CPU, a sound detection module for collecting pulse sound and a sound processing module for amplifying and filtering the collected pulse sound. In one measurement, the CPU is used for searching the pulse wave and pulse sound automatically, obtaining pulse wave and pulse wave sequence corresponding to cuff pressure, pulse sound and pulse sound sequence corresponding to cuff pressure, blood pressure data of an oscillation method and blood pressure data of an auscultatory method, giving reasonable and accurate final measurement result according to comparisonto two groups of blood pressure data and judgment of signal quality, and providing reliable data for diagnosing the blood pressure condition of patients accurately. Meanwhile, the invention realizes the self-adapting charging manner of determining the charging target pressure according to the pulse amplitude, and has the advantages of simple operation as well as rapid and accurate measurement.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to a blood pressure measurement module and a blood pressure measurement method. Background technique [0002] As the most important physiological parameter of the human body, blood pressure has extremely important clinical significance. At present, blood pressure measurement is mainly divided into two categories, one is invasive pressure (IBP). Its measurement is accurate, but its application is limited to special occasions such as the operating room because it needs to invade the body and has sterile requirements. The other is noninvasive blood pressure (NIBP). Compared with the invasive blood pressure (IBP) measurement method, the non-invasive blood pressure (NIBP) measurement method has the advantages of convenient measurement, simple operation, and no sterile requirements, so non-invasive blood pressure is replacing invasive blood pressure measurement in more and more occasi...
