Description

Technical Field

[0001] The present invention belongs to the technical field of medical devices, and in particular relates to a cardiac compression device for emergency treatment of cardiovascular diseases. Background Art

[0002] Cardiopulmonary resuscitation (CPR) is an emergency treatment measure, mainly for patients with cardiac arrest and respiratory arrest caused by various reasons. Its purpose is to quickly restore the patient's autonomous circulation and respiratory function through a series of rescue measures, thereby saving his life.

[0003] Cardiopulmonary resuscitation mainly includes three core steps: chest compression, open airway and artificial respiration. First, chest compression is to form a temporary artificial circulation by quickly and forcefully pressing the middle and lower part of the sternum, meet the blood supply needs of important organs such as the heart and brain, and promote the patient's recovery of spontaneous circulation. Secondly, open airway is to ensure that the patient's airway is unobstructed so that subsequent artificial respiration can proceed smoothly. Finally, artificial respiration is to blow fresh air into the patient's lungs through mouth-to-mouth or mouth-to-nose to achieve lung expansion and normal blood oxygen exchange, thereby restoring the patient's spontaneous breathing.

[0004] If conditions permit, the patient should be given electric defibrillation treatment as soon as possible to restore the heart's normal rhythm and contraction function through electric shock. In addition, the use of auxiliary measures such as vasoactive drugs can also improve the success rate of cardiopulmonary resuscitation to a certain extent.

[0005] It should be noted that cardiopulmonary resuscitation is a highly time-sensitive treatment measure. If the patient does not receive timely rescue and resuscitation after cardiac arrest, irreversible damage to the brain and other important organs and tissues may occur within 4-6 minutes. Therefore, when a patient's heart and respiratory arrest is found, cardiopulmonary resuscitation must be performed immediately on the spot, and a professional medical team must be contacted as soon as possible for further treatment. In general, cardiopulmonary resuscitation is a very important first aid skill, and mastering the correct operating methods and processes is of great significance to improving the patient's survival rate.

[0006] However, the current CPR heart compression operation in emergency situations usually involves the patient lying on a simple hard compression board, with medical staff who have mastered CPR skills manually performing heart compression and artificial respiration. However, in actual situations, CPR heart compression operations usually last from a few minutes to half an hour, and in very special cases, even more than half an hour. With an average of two compressions per second, hundreds to thousands of compressions are required, which is a great drain on the physical strength of the person performing the compressions. In addition, the continuity and standardization of the heart compression operation will gradually decrease over time due to physical exhaustion.

[0007] Therefore, it is necessary to provide a cardiac compression device for emergency treatment of cardiovascular diseases to replace artificial cardiac compression and solve the above-mentioned technical problems. Summary of the invention
