A peritoneal dialysis catheter belt is something you can make at home with basic sewing skills, a few dollars in fabric, and about an hour of time. The goal is simple: hold the catheter and transfer set snug against your body so the tubing doesn’t dangle, pull, or catch on anything. Commercial PD belts typically cost $25 to $50 and use stretchy, latex-free lycra with a pocket or loop system. You can replicate that design with the right materials and a few key principles that protect your exit site.
Choosing the Right Fabric
The fabric matters more than the design. Your belt sits against skin near a catheter exit site for hours at a time, often overnight during cycler sessions, so it needs to be breathable, soft, and moisture-wicking. A cotton-spandex blend (sometimes labeled cotton-lycra) in the range of 90% cotton and 10% spandex gives you stretch without trapping heat. Pure cotton works but won’t conform to your body as well. Avoid synthetic fabrics like polyester or nylon unless they’re specifically marketed as moisture-wicking athletic material, because they can trap sweat against the skin and create irritation.
Stay away from any fabric with latex content. Commercial PD belts are specifically made latex-free because latex allergies are more common in people who have repeated medical exposures. If you’re buying fabric from a craft store, cotton-spandex knit jersey is your best bet. It’s the same material used in stretchy T-shirts. Buy about half a yard, which is more than enough for one belt with leftover material for a second.
Measuring and Cutting the Belt
Measure your waist at the level where your catheter exits. This is usually at or just below the navel, not at your natural waistline. Add about two inches to that measurement for overlap at the closure. For width, cut the fabric 5 to 6 inches wide. Once folded and sewn, this gives you a finished belt roughly 2.5 to 3 inches tall, which is wide enough to hold the coiled catheter tubing and transfer set without bunching.
Cut one long rectangular strip to your waist measurement plus the two-inch overlap. Then cut a second smaller rectangle, about 5 inches wide and 4 to 5 inches tall, for the catheter pocket. This pocket is what actually holds the tubing in place.
Building the Pocket
The pocket is the most important part of the belt. It needs to hold your catheter and transfer set securely without pressing directly on the exit site itself. Position the pocket on the belt so it sits a few inches to the side of where the catheter exits your body. The tubing should loop gently from the exit site into the pocket with no tension or pulling.
Fold the pocket fabric in half (so it’s now roughly 2.5 by 4 inches), then sew the bottom and one side closed, leaving the top open. Pin it onto the main belt strip where you want it positioned, and sew three sides to the belt, leaving the top open for loading the tubing. Some people prefer two smaller pockets side by side: one for the coiled catheter and one for the transfer set connector. This keeps the heavier connector from swinging around separately.
An alternative to a sewn pocket is a simple loop system. Sew two or three small fabric loops (each about 1 inch wide) along the inside of the belt. The catheter slides through these loops and stays flat against your body. People who find pockets too bulky under clothing often prefer this approach, and it’s easier to sew.
Choosing a Closure Method
You have three main options for fastening the belt: Velcro, snaps, or a simple overlap with elastic tension.
- Velcro (hook-and-loop tape): The most adjustable option, but the hook side can snag on clothing or scratch skin if it curls. Sew the soft loop side against your skin and the hook side facing outward. Use a 2-inch wide strip for a secure hold. Some people find Velcro stiff and uncomfortable, especially during sleep.
- Fabric loops with a button or toggle: Sew a few buttonholes or fabric loops along one end and attach flat buttons to the other. This gives you size adjustability without any scratchy material. Flat buttons are more comfortable for sleeping than raised ones.
- Elastic overlap: If your fabric has enough stretch, you can simply make the belt slightly smaller than your waist measurement so it holds itself in place through tension, like a wide headband. This is the most comfortable for sleep but can ride up or shift if the elastic loosens over time.
Whatever you choose, make sure the closure sits on the opposite side of your body from the catheter pocket. You don’t want any bulk or hardware near the exit site.
Protecting the Exit Site
The single most important design principle is that nothing in your belt should press on, rub against, or pull at the catheter exit site. Friction at the exit site increases infection risk. The belt holds the tubing, not the catheter itself where it enters your body. Leave a gap or cutout in the belt fabric directly over the exit site, or simply position the pocket far enough to the side that the belt material passes over the exit site loosely.
When you load the tubing into the pocket, orient the catheter so it points laterally and slightly downward. This direction prevents moisture and skin debris from pooling at the exit site, which is the orientation recommended in clinical guidelines for reducing exit-site infections. Avoid coiling the tubing so that the transfer set points upward toward your chest.
If you notice any redness, itching, or rash under the belt, the fabric or closure material may be causing contact irritation. Dialysis patients are exposed to many potential allergens from dressings, antiseptics, and adhesives, and adding another material against the skin can trigger reactions. Switching to 100% cotton fabric and removing any adhesive tape components usually resolves the problem. If a rash develops specifically at the exit site, that needs clinical attention since it could signal infection rather than simple irritation.
Washing and Hygiene
Wash your belt frequently. A good rule is to wash it after every use if you wear it overnight, or every two to three days if you’re wearing it during the day under clothing. Use a gentle, fragrance-free detergent and wash on a warm cycle (not hot, which degrades spandex over time). Tumble dry on low or air dry. Making two or three belts at once lets you rotate through them while one is in the wash.
Always wash your hands before handling the belt and loading your catheter into it. The belt itself should be completely dry before you put it on. A damp belt sitting against a catheter dressing is a problem, since your dressing needs to stay clean and dry at all times. If the belt gets wet from sweat or a spill while you’re wearing it, swap it out for a dry one.
Making It Work for Sleep
If you’re on automated PD with a cycler at night, comfort during sleep is the real test. A few adjustments help. First, make the belt from the softest fabric you can find. A worn cotton T-shirt that you’d otherwise throw away is actually excellent material since it’s already been washed dozens of times and is as soft as it will ever get. Second, keep all seams on the outside of the belt rather than against your skin, or use French seams that enclose the raw edges. Third, skip Velcro entirely for a sleep belt and use the elastic overlap or button closure instead.
Some people find that a belt rides up during sleep no matter what. Adding a pair of thin fabric suspender-style straps that loop over the shoulders can keep it anchored. Another approach borrowed from the PD community is a simple lanyard-style necklace harness with a silicone loop at the bottom that holds the catheter connector against your chest. This works well for daytime use when you want something less bulky than a full belt.
