Description

Technical Field

[0001] The utility model relates to a cyclic visual cardiopulmonary resuscitation training device, belonging to the medical field. Background Technique

[0002] Cardiac arrest (CA) refers to the sudden cessation of the heart beat due to various reasons, which occurs unexpectedly and at an unexpected time, resulting in the sudden interruption of effective cardiac pump function and effective circulation, causing severe ischemia, hypoxia and metabolic disorders in all tissues and cells of the body. If not rescued in time, life will be lost immediately. Cardiac arrest is different from the cardiac arrest at the end stage of any chronic disease. If correct and effective resuscitation measures are taken in time, the patient may be saved and rehabilitated. Therefore, cardiopulmonary resuscitation after cardiac arrest must be carried out immediately on the spot.

[0003] Cardiopulmonary resuscitation is an emergency measure to rescue patients with cardiac arrest. By performing artificial chest compressions and artificial respiration, normal cardiopulmonary function is maintained until natural breathing and blood circulation are restored. Obtaining appropriate and effective first aid treatment at the first time of an emergency is one of the first aid skills that the general public must master. The existing cardiopulmonary resuscitation training models are relatively single, and the objects of cardiopulmonary resuscitation may be children, adolescents or adults. The pressing force for cardiopulmonary resuscitation of people in different age groups is different. The existing cardiopulmonary resuscitation training models are basically for adults and it is difficult to meet the usage requirements. Content of the Utility Model

[0004] Aiming at the deficiencies of the existing technology, the purpose of the utility model is to provide a cyclic visual cardiopulmonary resuscitation training device.

The compression depth indicator light is arranged on the bottom surface of the simulated human chest cover on both sides of the upper chest, and the compression depth indicator light is electrically connected to the circuit board.

[0026] In order to be able to provide real-time feedback on the compression frequency, the indicator light assembly includes a compression frequency indicator light. The compression frequency indicator light is set to simulate the sides of the human sternum through the neck to the temples on both sides. The correct compression frequency is preset on the circuit board.
