External chest pressing device for cardio-pulmonary resuscitation
Technical Field
The invention relates to a pressing device, in particular to an external chest pressing device for cardio-pulmonary resuscitation.
Background
Cardiopulmonary resuscitation is a critical rescue measure for critically ill patients with respiratory cardiac arrest, namely, the spontaneous pulsation which is formed by chest compression and is temporarily artificially circulated and recovered is adopted to replace spontaneous respiration. The carotid artery pulsation was observed, and when effective, one pulsation was felt after each compression. If the pulse stops after the compression stops, it indicates that the compression should be continued. If the beat persists after the cessation of compression, indicating that the patient's spontaneous heart beat has recovered, chest cardiac compression may be stopped.
The purpose of cardiopulmonary resuscitation is to open the airways, reestablish breathing and circulation. Cardiopulmonary resuscitation needs to keep the unobstructed of patient's respiratory track at first, uses simple and easy artificial respirator or mouth-to-mouth artificial respiration, observes the thorax and has the validity of deciding ventilating that does not have rhythmic uplift, when only one emergency person carries out cardiopulmonary resuscitation for patient when jointly pressing heart, should do 30 chest heart presses, carries out 2 artificial respiration in turn.
When cardiopulmonary resuscitation is performed on a patient, medical staff are used for performing chest compression on the patient to help the patient recover the pulse in the prior art, a manual compression mode needs trained medical staff, and the cardiopulmonary resuscitation is poor in effect and difficult to effectively rescue the patient for ordinary people who do not receive training; meanwhile, the chest needs to be matched with artificial respiration when being pressed, and in the prior art, medical workers need to press and carry out artificial respiration at the same time, so that the operation difficulty is high, and the effect is poor.
