The disposable surgical drape , also known as the operation sheet and sterile fenestrated drape , is an important medical supplies to create the operation environment. During the operation, the sterile surgical drape is laid on the patient, leaving the operation parts, and other adjacent parts are separated, so that the doctor can calmly carry out the operation without affecting the surrounding environment of the operation parts and complete the operation process.
Air permeability and water resistance are two basic properties of the surgical drape. The former is to ensure the normal respiratory function of the patient, and the latter is to prevent the body fluids from infiltrating through the surgical drape to the surface of the patient during the operation, requiring the water resistance of more than 10cmh2o. Because the fluid from the operation may carry various pathogens, if it passes through the surgical drape, it will pollute the operation environment. With the continuous improvement of people's living standards, disposable surgical drape have been gradually used in various surgical processes such as facial features department, all kinds of surgery, gynecology and obstetrics. Most of these surgical drapes are made of non-woven fabric, and their air permeability and water isolation can basically meet the requirements of operation.
