[0064] The following combined with specific examples, Figure 1-Figure 9 , the scheme in embodiment 1 is further introduced, see the following description for details:

[0065] The closed-loop automatic chest compression control system provided by the embodiment of the present invention includes: a signal preprocessing module, an input saturation processing module, a fuzzy control module, an output saturation processing module, and a fuzzy PID automatic adjustment module. The five modules are respectively described below detailed introduction:

[0066] 1. Signal preprocessing module

[0067] First, use a moving average filter (MAF) to filter PETCO2 and Kchest signals to eliminate power interference;

[0068] Among them, the digital processing algorithm of the moving average filter can be expressed by the following mathematical formula:

[0069]

[0070] In formula (1), M is the filter order, y(n) is the filtered signal, and x(n-k) is the original signal before filtering....

Abstract

The invention discloses a closed-loop automatic external chest compression control system capable of adaptively adjusting the external chest compression depth. The system comprises an input saturationprocessing module used for carrying out input saturation treatment on signals PETCO2 and Kchest after the band-pass filtering process, wherein the processed signals reflect the blood perfusion degreeand the fracture risk of a current patient, a fuzzy control module used for calculating to obtain a pressing depth adjusting increment according to the processed signals; an output saturation processing module used for carrying out optimization treatment on the pressing depth adjusting increment and outputting the optimized pressing depth adjusting increment; and a fuzzy PID automatic adjustmentmodule used for automatically adjusting the pressing depth of an external chest compression device according to the optimized pressing depth adjusting increment, and carrying out automatic external chest compression according to a target pressing depth value. According to the embodiments of the invention, based on the above design, the physiological status of a patient can be monitored in real time during the automatic external chest compression process. Meanwhile, the external chest compression depth can be automatically adjusted according to the physiological status of the patient. As a result, the safety of external chest compression is improved, and the better blood perfusion effect is achieved.

Description

technical field [0001] The invention relates to the field of chest compression control systems, in particular to a closed-loop automatic chest compression control system capable of adaptively adjusting the depth of chest compressions. Background technique [0002] The failure of various organs caused by cardiac arrest is caused by a sudden hypoxic blow. At present, cardiopulmonary resuscitation (CPR) is the only effective way to treat such diseases. Chest compressions are an important part of CPR. Chest compressions generate blood flow by increasing intrathoracic pressure or directly squeezing the heart, providing the brain and other vital organs with the oxygen supply necessary to re-establish autonomous blood circulation. Therefore, in order to improve the quality of chest compressions, many new technologies to improve the efficiency of chest compressions have emerged in recent years. The main technological innovations are reflected in two aspects: chest compression qua...
