Application: The series of cardiopulmonary resuscitators are reasonably designed, compact, and lightweight, and can be widely used in first-aid environments such as in-hospital, out-of-hospital, and grass-roots communities.

(1) The heart compression is fast and strong, and the thorax fully rebounds after compression.

     (2) The patient's required compression depth can be indicated according to 20% of the patient's chest thickness to ensure mechanical chest compressions

     (3) The instrument is equipped with a time / volume type ventilator, which can automatically perform mechanical ventilation during chest compressions, and provides a variety of compression ratio options.

     (4) The adjustment range of chest compression depth is large (0-8cm), which meets the requirements of the 2010 cardiopulmonary resuscitation and cardiovascular emergency guidelines.

     (5) Depth of cardiac compression In the process of chest compression, manual intervention, control, and safety of chest compression can be ensured at any time.

     (6), can work continuously for a long time, no special consumables in use.
