Description

Traditional Chinese medicine bone-knitting small splint

Technical Field

The invention relates to the field of medical instruments, in particular to a small traditional Chinese medicine bone-knitting splint.

Background

When treating a fracture, it is often necessary to fix the fracture site with a splint. The inner lining of the traditional Chinese medicine small bone-knitting splint in the prior art usually adopts foam, when a doctor uses the inner lining to fix the fracture externally, local pressure is overlarge due to local bone bulge or fracture deformity, and skin red and swelling, pressure sore or skin necrosis are easily formed after a long time. When the traditional Chinese medicine bone-knitting small splint is used for external fixation of fracture, the tightness is difficult to adjust, and the fracture is not firmly fixed due to over-loosening, so that the affected limb is ischemic. Meanwhile, the swelling of the affected limb after fracture is aggravated along with time, and even if the tightness is adjusted initially, the affected limb becomes too tight due to swelling in the later period, so that ischemic necrosis of the affected limb is caused clinically seriously.
