Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to a cardiac resuscitation device. Background Technology

[0002] In the field of cardiac resuscitation, traditional manual cardiopulmonary resuscitation (CPR) methods rely on rescuers to continuously perform chest compressions and artificial respiration to maintain blood circulation and oxygen supply for patients with cardiac arrest.

[0003] Among these challenges, sustained high-quality chest compressions are extremely energy-intensive, causing rescuers to quickly become fatigued. This makes it difficult to maintain key indicators such as compression depth, frequency, and chest recoil within the recommended guidelines, thus affecting resuscitation outcomes. Different operators have varying compression techniques, strength, and frequency, and even trained medical personnel may experience differences in resuscitation quality due to individual variations. Providing timely and correct artificial respiration, especially while performing chest compressions, is a challenge for the operator and may be difficult to perform aseptically in emergency situations, increasing the risk of infection. Furthermore, during manual CPR, it is difficult to monitor compression quality in real time, such as compression depth, frequency, and chest recoil, lacking an immediate feedback mechanism and hindering timely adjustments to resuscitation strategies.

[0004] In view of the above problems, this utility model proposes a cardiac resuscitation device, which aims to overcome the limitations of existing technologies and improve the success rate and quality of life of cardiac arrest patients through automation and intelligent means.
