Description

Technical Field

[0001] This utility model relates to the field of locking device technology, and in particular to a rapid locking mechanism and a cardiopulmonary resuscitation device. Background Technology

[0002] Cardiopulmonary resuscitation (CPR) machines are a type of medical emergency equipment that uses machinery to perform basic life support operations such as artificial respiration (mechanical ventilation) and chest compressions instead of human labor; rapid and stable chest compressions are especially important when a patient experiences cardiac arrest.

[0003] Currently available cardiopulmonary resuscitation (CPR) machines, such as the "electric CPR compression device" disclosed in Chinese patent CN206630870U, are a type of CPR machine. This electric CPR compression device includes a resuscitation plate and a head, which are connected by a detachable connection structure.

[0004] In use, the resuscitation board needs to be secured to the transport stretcher first, then the machine head is connected to the resuscitation board. The patient lies on the resuscitation board, and the machine head can perform chest compressions for cardiopulmonary resuscitation (CPR). The problem with existing technology is that the golden time for CPR is only a few minutes, so a rapid connection between the CPR machine and the transport stretcher is necessary. This requires the resuscitation board to be quickly secured to the stretcher. The current method of securing the resuscitation board to the stretcher using straps affects the fixation time, thus impacting the effectiveness of CPR on the patient. Utility Model Content
