Technical Field
[0001] The present invention relates to the technical field of medical devices, and in particular to a cardiopulmonary resuscitation machine with intelligent depth adjustment and an adjustment system thereof. Background Art
[0002] Cardiopulmonary Resuscitation (CPR) is a life-saving technique for cardiac and respiratory arrest. It is used to perform external chest compressions on patients with acute cardiac arrest in order to restore the patient's spontaneous breathing and circulation. It is the most common and effective first aid method in medical emergency.
[0003] Cardiopulmonary resuscitation machine, also commonly known as cardiopulmonary resuscitation instrument, is a type of equipment that uses machinery to replace human power to perform basic life support operations such as artificial respiration (mechanical ventilation) and chest compression. It can be divided into two types: electric cardiopulmonary resuscitation machine and pneumatic cardiopulmonary resuscitation machine. This type of equipment can provide a high level of uninterrupted artificial circulation and ventilation support, and some portable and movable cardiopulmonary resuscitation machines can be used in pre-hospital emergency care, and their work will not be significantly affected even during the process of transporting patients.
[0004] However, existing cardiopulmonary resuscitation machines lack their own sensing equipment, and the naked eye cannot judge whether the compression depth of the cardiopulmonary resuscitation machine is appropriate. When the patient's chest is under too much pressure, it is easy to cause the patient's rib fractures. In addition, the thickness of the patient's chest muscles will also affect the compression depth during cardiopulmonary resuscitation. Current cardiopulmonary resuscitation machines cannot adjust the compression depth according to different muscle thicknesses. Summary of the invention
