Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to a cardiac resuscitator used for critically ill patients. Background Art

[0002] Cardiac arrest refers to the sudden cessation of heart beating caused by various reasons in unexpected circumstances and time, which leads to the sudden cessation of effective cardiac pump function and effective circulation, causing severe ischemia, hypoxia and metabolic disorders of tissue cells throughout the body. If not rescued in time, life can be lost immediately. Cardiac arrest is different from any terminal cardiac arrest of chronic diseases. If correct and effective resuscitation measures are taken in time, the patient may be saved and recover.

[0003] During the cardiac resuscitation of a critically ill patient, it is necessary to press the chest of the critically ill patient for a long time. Some existing cardiac resuscitators are small handheld devices. During the long-term pressing process, the pressing head of the existing resuscitator easily deviates from the optimal pressing position of the heart, which undoubtedly reduces the pressing effect.

[0004] In view of the above problems, the present utility model is proposed. Utility Model Content
