Bard medical supplies, like catheters and drainage bags, are easy to work with. If you need to modify the length of the tubing on the drainage bag, you may shorten it prior to your first use. Sterilize your scissors and the end of the drainage tube and cut to your desired length. Sterilize the end of the tube again once you have reached your desired length. Then connect the tube to the connector of the drainage bag and clamp shut.
