Abstract

The invention discloses a pulse wave acquisition quality real-time analysis device, which can analyze and process pulse wave signals in real time, and comprises a data input module, a data buffer and pretreatment module, a data analysis module, a weight setting module and an evaluation module, wherein a plurality of assay values xj are obtained in the data analysis module, weight coefficients Cj are arranged in the weight setting module, the assay values xj are respectively calculated in the evaluation module to obtain evaluation values Xj* corresponding to the assay values xj, and the evaluation values Xj* are weighted to sum by adopting the weight coefficients Cj, thereby obtaining acquisition quality real-time scores GI, automatically distinguishing quality of the pulse wave signals, and effectively increasing degree of automation of pulse wave acquisition.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to a pulse wave acquisition quality real-time analysis device, which analyzes and processes the collected pulse wave, outputs a pulse wave real-time acquisition quality score, automatically recognizes the pulse wave signal quality, and displays it through a display module , and the analysis results can be output through the data output module. Background technique [0002] Pulsography is a non-invasive detection method that detects changes in blood volume in living tissue by photoelectric means. Pulse waves contain rich hemodynamic information. [0003] The pulse wave detection equipment currently used in clinical practice is often affected by external or self-interference due to different working environments in actual clinical detection, which brings difficulties to the pulse wave extraction and affects the normal operation of the system and the use of the instrument. ...
