External chest compression physiological feedback signal simulator

Abstract

The invention discloses an external chest compression physiological feedback signal simulator, which comprises a displacement sampling module, a keyboard, a microcontroller and a liquid crystal display screen, wherein the microcontroller receives external chest compression depth signals from the displacement sampling module and processes the signals into corresponding external chest compression depth data, the microcontroller acquires external chest compression frequency data by calculating the periodical change times of the external chest compression depth signals in unit time, and the microcontroller also receives chest pump factor data and safety range data from the keyboard; and the microcontroller processes the external chest compression depth data, the external chest compression frequency data, the chest pump factor data and the safety range data based on an external chest compression feedback physiological signal simulation model through corresponding simulation algorithm programs to acquire coronary perfusion pressure simulation data, mean arterial relaxation pressure simulation data and end-tidal carbon dioxide partial pressure simulation data. The simulator can be used for first-aid training, and fulfills the purpose of improving the external chest compression efficiency by adopting a personalized first-aid scheme.

Description

technical field [0001] The invention relates to a medical physiological signal simulator, in particular to a chest compression physiological feedback signal simulator. Background technique [0002] Rescue patients in sudden cardiac arrest, usually take the first aid method of chest compressions. The main purpose of chest compressions is to provide timely blood supply to important organs of the human body such as the brain and heart, and promote the re-establishment of the autonomous blood circulation of the human body. Therefore, during the first aid process, the blood flow of the human blood circulation is the core index for evaluating the quality of chest compressions. Physiological parameters related to human blood circulation and blood flow (such as coronary perfusion pressure, end-tidal partial pressure of carbon dioxide, and mean arterial diastolic pressure) are the core indicators for evaluating the quality of chest compressions during emergency rescue. Coronary Per...
