Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to a cardiopulmonary resuscitation self-help training device. Background Art

[0002] Cardiopulmonary resuscitation and defibrillation (CPR-D) is the most effective method for rescuing cardiac arrest. Looking at the publicity and training of CPR-D among the public in China: on the one hand, knowledge publicity is mostly promoted in the form of videos and texts, which can better enhance the public's understanding of CPR-D, but due to the lack of practical skills, the public cannot really master the key rescue techniques; on the other hand, skill training is mostly carried out in a centralized manner with instructors as the center, which can enable the public to learn and update CPR-D related knowledge and skills more comprehensively within a specific time, but it may be limited by problems such as work-study contradictions, training costs, and training willingness, resulting in the inability to achieve the expected popularization. Therefore, how to effectively fill the shortcomings of the above two models and play a synergistic role with them to popularize the public's CPR-D knowledge and skills to the greatest extent is an important issue in the current innovation of public cardiopulmonary resuscitation training models; the summary of the latest international cardiopulmonary resuscitation guidelines in 2020 provides a solution to this issue in the "Resuscitation Education Science" section: For non-professionals, self-training is recommended to improve their willingness and ability to perform cardiopulmonary resuscitation and defibrillation, and virtual reality and gamification learning can be included in resuscitation training; and in cardiopulmonary resuscitation training, a self-service training device is required for auxiliary training.

[0003] However, as far as the current traditional CPR self-help training equipment is concerned, it can usually only provide auxiliary feedback training on chest compression techniques, and cannot provide feedback prompts from the physiological indicators improved by chest compression. Physiological indicators can more objectively and directly reflect the quality of chest compression than technique-related indicators. End-tidal carbon dioxide partial pressure as a physiological indicator can effectively reflect the quality of chest compression and whether the patient with cardiac arrest has recovered spontaneous circulation.
