Background

Epidural anesthesia refers to epidural space block anesthesia, i.e., the injection of local anesthetics into the epidural space to block the spinal nerve roots, temporarily paralyzing its innervating areas, known as epidural space block anesthesia, and simply as epidural block. Because the pipe diameter of the catheter is smaller, the existing fixing scheme is to use adhesive tape for pasting and fixing and external fixing during operation, but the fixing mode is unstable and firm, the epidural catheter is easy to shake and loosen, and the catheter can even fall off during fixing of a patient. For this purpose, we propose an anesthesia epidural catheter fixation patch.
