Portable cardiopulmonary resuscitation device with precise compression depth anduniformity

摘要

Portable cardiopulmonary resuscitation device with precise compression depth and uniformity, including a frame body and a compression mechanism associate with the frame body. The compression mechanism includes a handle and a connecting bar connected between the handle and a coupling seat. An adjusting bolt is passed through the coupling seat and movably screwed in a locating block. At least one movable sleeve is disposed on one side of, above or below the locating block. The movable sleeve slide along a retaining shaft which is vertically jointed to a fixing frame. A lower end of adjusting bolt is connected with a plunger. The other end of the coupling seat is further connected with another connecting bar which is connected to the frame body. Two sitting bars are connected between the two transverse beams of the frame body. When rescuing a victim, a rescuer can sit on the sitting bars with the rescuer's weight offsetting a reaction force produced in compression of the heart. The frame body can be associated with a base board which is fixed on an emergency litter, enabling a rescuer to perform cardiopulmonary resuscitation in a moving ambulance.
