A radial artery compression device is a medical device used to compress the radial artery in the wrist after procedures such as cardiac catheterization or angiography. The device is designed to prevent bleeding from the site where the catheter is inserted and to help the artery heal. The device usually consists of a soft, inflatable cuff that is worn over the wrist and inflated with air to apply pressure to the radial artery. Then secure the cuff in place with straps or straps. The amount of pressure applied can be adjusted to achieve the desired level of compression. The device is usually left in place for several hours after surgery to ensure the artery has time to heal properly.
