Technical Field

The invention relates to the technical field of emergency department instruments, in particular to a cardiopulmonary resuscitation device with high safety performance for an emergency department.

Background

The emergency medical department or emergency medical center is the department with the most centralized and most various severe patients and the most important rescue and management tasks in hospitals, and is the necessary way for all emergency patients to be admitted for treatment.

Currently, cardiopulmonary resuscitation with extra-thoracic cardiac compression is sometimes required during emergency treatment. Traditional cardiopulmonary resuscitation relies on the personnel of suing and labouring to carry out artificial respiration and heart to the patient and presses to help the sick and wounded person to maintain blood oxygen concentration, but because the mode of adopting artifical bare-handed rescue to press amplitude, frequency differ, can't press for a long time, its effect that makes patient's cardiopulmonary resuscitation is not good. In the conventional cardiopulmonary resuscitation, the resuscitation effect may be affected by the fracture of the patient's ribs due to the over-violent force, so that the effective circulation and respiration are difficult to ensure, and the rescue effect is finally affected.

The prior patent CN 108670788A discloses a cardiopulmonary resuscitation device for emergency treatment, which comprises a bed board, a pressing rod, an elastic air bag, a pressing suction cup and a controller; the both sides of bed board are equipped with the slide rail, be equipped with two flexible bracing pieces on the bed board, the bottom of two flexible bracing pieces all is equipped with the slider, the slider uses with the slide rail phase-match, all be equipped with L type sleeve pipe and two flexible bracing piece suit in L type sheathed tube one end on two flexible bracing pieces, all overlap in two L type sheathed tube other ends and be equipped with the horizon bar, be fixed with the motor case between two horizon bars, be equipped with battery and servo motor in the motor case, servo motor's output shaft has the cam, the cam below is equipped with the gyro wheel, the depression bar is connected to the gyro wheel below, the cover is equipped with buffer spring on the depression bar, the depression bar.
