The part of the harness that needs to be reinforced is determined according to the user's physical condition and the parts that may have problems such as fractures. The reinforcement plate 12 is attached behind the position that needs to be reinforced, and the fixing belt 16 of the corresponding part is passed through the through groove 15 and tied and fixed, so that the reinforcement plate 12 is attached to the back of the fracture site to prevent the limb at that site from shaking.
[0033] In summary, the helicopter rescue pre-fixation device, by setting the harness body 1, the arm guard 2 and the leg guard 3, is combined to form a wearable harness that fits the human body. The harness is tied to the back of the human body by using the collar 17, the first positioning belt 18, the second positioning belt 21 and the third positioning belt 23 provided on the harness. The reinforcement plate 12 is combined with the fixing belt 16 and thus tied to the rear of the harness, which reinforces and supports the limbs corresponding to the reinforcement plate 12, thereby preventing the fractured part of the wearer from shaking during the helicopter hoisting process, avoiding secondary injury to the fractured part.
