1. A portable automated chest-abdominal compression (CC-AC) device used in confined spaces, comprising: a compression mechanism, a driving mechanism, a detection module and a control module,
wherein the compression mechanism comprises a strap fixing module, a compression plate connected to the strap fixing module, and a compression piston arranged on one side of the compression plate,
wherein the driving mechanism is configured to perform an action for driving the compression piston,
wherein the detection module comprises a displacement sensor arranged on the compression piston, and a pressure sensor arranged on another side of the compression plate, the detection module is configured to respectively detect a compression depth and a compression pressure,
wherein the control module receives the detected compression depth and the detected compression pressure, and is configured to:
obtain a compensation value of time of a single compression according to the received compression depth and a target depth, to control an action of the driving mechanism during a chest compression (CC) process; and
construct an abdominal mechanics model according to the received compression depth and the received compression pressure, and compensate the received compression depth according to a target pressure by using the abdominal mechanics model, to control an action of the driving mechanism during an abdomen compression (AC) process.
