The sterile fenestrated drape is made of biplex nonwoven. One side is absorbent , the other side is waterproof. The surgical fenestrated drape has excellent barrier and repels all kinds of liquids and body fluids (including blood) that appear in the operation. It has the two-way function of blocking microbial infiltration into surgical wounds and protecting medical personnel, and has good gas permeability. With good "breathing" performance, the medical staff can be in good comfort during long periods of time and large fluid discharge. Holes can fully reveal the surgical field of view, which is conducive to intraoperative positioning.
