Pneumatic stiffness-variable and wearable external skeleton for human spine protection

Abstract

The invention relates to a pneumatic stiffness-variable and wearable external skeleton for human spine protection, and belongs to the field of body protection devices. The pneumatic stiffness-variableand wearable external skeleton includes a hard protective unit, a flexible protective unit, a pneumatic power unit, a detection unit and a control unit; the hard protective unit includes a helmet; the flexible protective unit includes a pneumatic stiffness-variable spine, a pneumatic stiffness-variable neck protector and a pneumatic stiffness-variable body protective meridians and is used for being connected with the hard protective unit to form a hooded open front vest structure; the pneumatic power unit is controlled by the control unit to rapidly inflate a pneumatic stiffness-variable module; the detection unit is used for detecting the change of external environments; and the control unit is used for receiving a detection signal outputted by the detection unit, and outputs a control signal of starting rapid inflation to the pneumatic power unit when the detection signal indicates that the change of the external environments reaches a preset condition. The pneumatic stiffness-variable and wearable external skeleton for human spine protection has the advantages of not only reducing the impact on movements of wearers, but also protecting key parts of the spine from being damaged,and can be widely used in the fields of protection and medical treatment.

Description

technical field [0001] The invention relates to the field of body protection devices, in particular to a wearable exoskeleton with aerodynamic variable stiffness for human spine protection. Background technique [0002] The spine is the central axis of the human body, connected by ligaments, joints and intervertebral discs. The inside of the spine forms a longitudinal spinal canal from top to bottom, containing the spinal cord. The spine has the functions of supporting the trunk, protecting the internal organs, protecting the spinal cord and performing movements. Spinal injuries often occur in industrial and mining, traffic accidents, and can occur in batches during wartime and natural disasters. The injuries are serious and complicated, with multiple injuries and compound injuries, and many complications. When combined with spinal cord injuries, the prognosis is poor, and even life-long disability or life-threatening. Most of the causes of spinal injuries are traumatic v...

Problems solved by technology

[0003] Spinal protection is the only effective strategy to reduce spinal injuries. For example, the patent document CN208114027U discloses a protective vest, which includes a wearing structure and a protective structure. The wearing structure is the vest body, and the protective structure is the vest on the vest body. The laminated armor group on the midline, the upper armor skirt of the laminated armor group is pressed against the lower armor body to completely cover the wearer's spine with the armor group when being hit or collided. Most of the impact force is to protect the spine from injury. Although the purpose of protecting the spine is achieved, it will greatly restrict the wearer's movement
