Embodiment Construction

[0024] Traditional physiological parameter processing strategies are researched and improved based on a single physiological signal, and are used to improve the physiological parameter estimation of the signal under the condition of single physiological signal noise, such as classical filtering, machine self-learning, Kalman filtering, transform domain analysis, etc., but these None of the technologies can solve the problem of noise influence very well, and some algorithms are computationally complex, require a lot of resources and are difficult to implement in engineering. At the same time, there is also a method of selecting reasonable physiological data from multiple physiological data sources, but it has not been able to solve the problem of false alarms or missed alarms caused by noise, and the scope of application is small.

[0025] Therefore, a physiological parameter processing method is proposed, which selects one signal as the main physiological signal, selects at lea...

Abstract

A physiological parameter processing method includes acquiring a main physiological signal, and analyzing the main physiological signal to acquire the signal quality indexes of the main physiological signal; acquiring auxiliary physiological signals, and analyzing the auxiliary physiological signals to acquire the signal quality indexes of the auxiliary physiological signals; controlling the physiological parameter acquiring process by processing the main physiological signal according to the signal quality indexes of the main physiological signal and the signal quality indexes of the auxiliary physiological signals; outputting the physiological parameters. The physiological parameter processing method has the advantages that the auxiliary physiological signals are utilized to assist with main physiological signal processing, the information source is expanded as compared with that of a processing manner relying on one single physiological signal, especially when the signal quality of the single physiological signal is poor, and the false alarms and alarm failures can be avoided by the aid of the auxiliary physiological signals; in addition, the invention further provides a physiological parameter processing system and monitoring equipment adopting the physiological parameter processing method and system.

Description

technical field [0001] The invention relates to medical equipment, in particular to a monitoring equipment and a physiological parameter processing method and system thereof. Background technique [0002] It is widely used to process the vital sign signal of human body to obtain physiological parameters. However, these vital sign signals are often disturbed by noise, artifacts, etc., causing errors in physiological parameters. Taking monitoring equipment as an example, the wrong estimation of arrhythmia will lead to related false alarms. These false alarms reduce the satisfaction of patients and medical staff with the equipment. May ignore the real critical situation, greatly weakening the monitoring effect. Contents of the invention [0003] Based on this, it is necessary to provide a monitoring device and its physiological parameter processing method and system for false alarms caused by signal interference. [0004] A physiological parameter processing method, compri...
