Embodiment Construction

[0027] In order to further understand the invention content, characteristics and effects of the present invention, the following examples are given, and detailed descriptions are as follows in conjunction with the accompanying drawings:

[0028] see figure 1 , a closed-loop chest compression system, including a feedback physiological signal acquisition module, a post-processing amplification module, an intelligent controller, a control interface, an electric chest compressor, and a chest thickness signal acquisition module.

[0029] The above chest thickness signal acquisition module is used to acquire the chest thickness signal of the patient. In this embodiment, the chest thickness signal acquisition module is a displacement sensor, which is installed in the electric chest compressor, and transmits the chest thickness signal to the intelligent controller through the control interface.

[0030] The above-mentioned feedback physiological signal acquisition module includes an ...

Abstract

The invention discloses a closed-loop external chest compression system. The system comprises a feedback physiological signal acquiring module, a postprocessing and amplifying module, an intelligent controller, a control interface, an electrical external chest compressor and a chest thickness signal acquiring module, wherein the intelligent controller samples an analogue signal which comes from the postprocessing and amplifying module and a patient chest thickness signal which is sampled by the chest thickness signal acquiring module, compares the analogue signal which reflects actual feedback physiological information with a target physiological signal, and generates the depth and frequency control signal of the external chest compression to be implemented, which can accord with the target physiological signal, by combining a fuzzy control algorithm or a fuzzy proportional integral differential (PID) control algorithm. By continuously monitoring partial pressure of end-tidal carbon dioxide (PETCO2) and mean arterial pressure (MARP) in real time and using the feedback physiological signal, the closed-loop control over the depth and the frequency of the external chest compression is performed on the basis of the fuzzy control algorithm or the fuzzy PID control algorithm. The closed-loop external chest compression system is suitable for pre-hospital emergency treatment and continuous treatment of patients with sudden cardiac arrest.

Description

technical field [0001] The invention relates to a chest compression system, in particular to a closed-loop chest compression system. Background technique [0002] Since 1960, Kouwenhoven, Jude, and Knickerbocker revealed the important role of chest compressions in maintaining blood circulation in patients with ventricular fibrillation, chest compressions have been used as the core first aid measures and cardiopulmonary resuscitation for resuscitating cardiac arrest patients A key link in technology. 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. However, in practice, almost all chest compression operations only use the unified standard of comp...
