To reduce damage or coring of the septum (cutting out small pieces of membrane with the needle, plugging it up), low or non coring needles are to be used. After each use, a heparin lock is made by injecting a small amount of heparinized saline (an anticoagulant) into the device, preventing development of clots within the<unk> or catheter. In some catheter designs where there is a self-sealing valve at the far end, the system is locked with just saline. The<unk> can be left accessed for as long as required. The<unk> is covered in a dressing to protect the site from infection and to secure the needle in position. If a<unk> is used infrequently, it may be necessary to access the<unk> regularly, flush it with saline, and inject a new heparin lock to prevent clotting between uses.
