External chest compression device for cardiopulmonary resuscitation

Abstract

The invention provides an external chest compression device for cardiopulmonary resuscitation, and effectively solves the problems that in the prior art, cardiopulmonary resuscitation apparatuses aretedious to operate, the compression depth is not liable to control, the adaptability is limited, the compression depth cannot be automatically adjusted according to different individuals, the efficiency and quality of compression are influenced, and the rescuing time is delayed. The technical scheme of the external chest compression device for solving the problems is characterized by comprising aslab, wherein a horizontal plate is arranged on the lower side of the slab; supporting rods are fixed to the lower end surface of the slab; a first connecting rod is arranged on the lower side of theslab; a first gear is arranged on the first connecting rod; a transmission gear is arranged at the lower end of the first connecting rod; a second gear is arranged on the lower side of the transmission gear; a second connecting rod is arranged on the left side of the second gear; a vertical plate is arranged on the upper side of the horizontal plate; a pressure rod is arranged on the horizontal plate in a penetrating manner; a pressing block is arranged at the lower end of the pressure rod; a first wedge-shaped block is arranged at the upper end of the pressure rod; a cam is arranged at the right end of the second gear; a horizontal rod is arranged above the right end of the horizontal plate; a vertical rod is arranged at the left end of the horizontal rod; a sloping plate is arranged on the horizontal plate; a sliding groove is formed in the sloping plate; the horizontal rod is arranged in the sliding groove; and a wedge-shaped protrusion is arranged on the horizontal rod.

Description

technical field [0001] The invention relates to the technical field of emergency treatment equipment, in particular to a chest compression device for cardiopulmonary resuscitation. Background technique [0002] Traditional chest resuscitation mostly uses the operator's hands on the chest compression part of the patient to press rhythmically to achieve. In the old guideline, the compression requirements were as follows: the depth of compression depression was 3-5cm, and the compression frequency was 100-120 times / min, so the operation intensity was relatively high. In the actual operation, often because the operator's arm is not straight, resulting in uneven force on the palm; or because the operator's physical exertion is too large, the operator needs to be replaced frequently and many other reasons, which affect the effect of pressing, especially prone to rib fractures and other complications. [0003] In the new guidelines, "For children (including infants [less than one...
