Merit Medical Systems Drainage Products

Merit Medical Systems manufactures drainage solutions built around a single priority: managing fluid safely and comfortably outside the clinical setting, so patients and caregivers can handle routine drainage at home with confidence. This collection centers on the Aspira pleural and peritoneal drainage line and the Merit Drainage Depot urinary system — both engineered for sterile, closed-system performance that reduces infection risk between drainage sessions.

For patients managing recurrent pleural effusions or malignant ascites, the Aspira Drain Bags (4992301) arrive as complete 1,000 mL sterile kits, packed with a catheter valve cap, slide clamp, and two prep wipes — everything needed for one clean drainage cycle without hunting for extra supplies. The companion Aspira Dressing Kits (4991503) handle the other half of the routine: sterile, disposable components for keeping the catheter exit site clean between drains. Because the dressing kits ship without a drainage bag, many caregivers stock both items together so nothing runs short mid-week.

On the urinary side, the Merit Drainage Depot Urinary Drainage Bag (MDD600) offers a 600 mL capacity with 24-inch tubing and a built-in anti-reflux barrier that helps prevent backflow toward the bladder — a key detail for reducing catheter-associated urinary tract infection risk. A male-specific version with a Velcro securement strap adds discreet, comfortable leg attachment for ambulatory patients.

Buyers most often ask whether these components are interchangeable and how frequently to replace them. Aspira bags and dressing kits are single-use and sterile — one bag per drainage session, dressings changed per your clinician's schedule — while the Merit Drainage Depot bag is designed for the standard replacement interval your care team recommends. Matching the manufacturer's own bags, caps, and dressings keeps the drainage system closed and validated end to end.
