Abstract:
Portable cardiopulmonary resuscitation device with precise compression depth and uniformity, comprising:a frame body composed of two transverse beams and two U-shaped bars which are perpendicularly connected with the transverse beams to form the frame body with four supporting legs; anda compression mechanism including a connecting bar, one end of which is pivotally connected with one of the transverse beams of the frame body, while the other end of which is a free end connected with a handle positioned above the other transverse beam for up and down movement and operation, a set of movable sleeve and retaining shaft being disposed on at least one side of, above or below the connecting bar, the movable sleeve being fitted around the vertical retaining shaft and restricted thereby to only move up and down, the movable sleeve being connected with the connecting bar, while the vertical retaining shaft being fixed on the frame body via a fixing frame and bridge bars so as to ensure up and down movement of the connecting bar, a compression depth adjusting mechanism being disposed on the connecting bar, a lower end of the compression depth adjusting mechanism being connected with a plunger for pressing the heart of the person who needs the operation,wherein, the compression depth of the plunger is controlled and adjusted by a mechanical device for elevating and descending, hydraulic measure or pneumatic measure, one of the transverse beams of the frame body serving as a stopper for restricting the compression depth of the connecting bar and the plunger and avoiding over-compression of the heart.
