What is the padding board for arterial indwelling needle fixation?

An arterial catheter stabilization board is a common medical device made of sturdy material. It features a round base pad with a support tube attached on top. The support tube has several sections of soft, durable tubing, and at the upper end is a square metal support bracket. This metal bracket contains two holes, one of which is designed for holding the indwelling needle. The primary function of the arterial catheter stabilization board is to protect the patient's blood vessel. When the indwelling needle is inserted into the patient's vessel, using the board effectively prevents the needle from slipping out and avoids compression of the vessel. Additionally, the metal support bracket shown in images of the arterial catheter stabilization board can withstand certain pressure, ensuring that the inserted indwelling needle remains more secure.
