Description

Technical Field

[0001] The utility model relates to the technical field of cardiopulmonary resuscitation training models, in particular to a half-hearted cardiopulmonary resuscitation training and assessment system. Background Art

[0002] Cardiopulmonary resuscitation (CPR) refers to the rescue process of opening the airway, chest compression, artificial oral and nasal respiration, endotracheal intubation, external defibrillation, etc., which is taken for people with cardiac arrest caused by various reasons, so that patients can receive care in a short time. Whether the actions during the rescue process are standardized and correct is the key to the successful rescue of the patient.

[0003] Traditionally, CPR training involves students experiencing the process on actual patients. However, this approach lacks practical examples and presents significant training limitations. Therefore, the use of CPR manikins for simulation demonstrations and training can address these issues. However, many current CPR manikins offer limited functionality, failing to simulate pupillary light reflexes or spontaneous carotid artery pulsation, and the training feedback is often less than intuitive.

[0024] Furthermore, a simulated pulse vibrator 11 is provided at the carotid artery position of the neck of the simulated human body 1, and the simulated pulse vibrator 11 is electrically connected to the control circuit board 7.
