Description

Technical Field

[0001] The utility model belongs to the technical field of medical equipment, and more specifically relates to a flail chest belt for rib fractures. Background Art

[0002] Flail chest refers to the closed fracture of multiple ribs in multiple places due to external violent injury, usually more than five ribs, with more than two fractures on one rib. Due to the rib fracture, the local chest loses support, forming a softening area. Unlike normal breathing, the chest bulges outwards when inhaling and collapses inwards when exhaling, the softening area collapses inwards when inhaling and bulges outwards when exhaling, which is an abnormal movement. This situation is called flail chest.

[0003] During the treatment of rib fracture flail chest, it is usually necessary to use an external strap to tie up the chest and abdomen to reduce the movement of the fractured ribs. In the prior art, a cavity is usually set inside the strap, and gas is filled into the cavity to improve the fit of the strap to the chest and abdomen, thereby improving the fixation effect of the fractured ribs. However, in the actual treatment process, due to the different injuries suffered by the patients, the area of ​​their rib fractures will also vary greatly, and it is usually difficult to satisfy the reinforcement effect of the local rib fracture area by inflating the entire strap.
