Why Secure Connections and Anti-Reflux Protection Matter

In catheter care, two factors critically impact patient safety and comfort: secure connections that prevent disconnects and anti-reflux protection that stops urine from flowing backward toward the bladder. Accidental disconnections during patient movement create infection risk, drainage interruptions, and cleanup challenges. Meanwhile, backflow allows bacteria from collected urine to travel back into the bladder, significantly increasing urinary tract infection risk. This drainage bag addresses both concerns with Luer-Lock twist-to-secure connections and an integrated anti-reflux tower—essential features for overnight use, high-output situations, or extended care when reliable, infection-safe drainage is critical.

Perfect for: Overnight bedside drainage, post-surgical catheter management, long-term care facilities, home care patients, high urine output situations, or anyone requiring secure, large-capacity collection with infection prevention features.

What You'll Appreciate

Secure connection confidence — The Luer-Lock system creates a reliable seal that won't accidentally pull apart during patient movement, repositioning, or transfers. Fewer disconnects mean less mess and reduced infection risk.

Infection prevention built-in — The anti-reflux tower creates one-way flow that allows urine to enter the bag but prevents it from flowing back toward the bladder. This mechanical feature provides critical protection against catheter-associated urinary tract infections.

Full night capacity — At 4000mL, this bag handles overnight drainage without requiring nighttime emptying for most patients. Better sleep for patients, fewer interruptions for caregivers.

One-hand emptying — The slide-tap valve opens with a simple thumb motion, allowing quick drainage into toilet or measuring container. No complicated operation needed—especially helpful when managing multiple patients.

Accurate output monitoring — Bold, easy-to-read graduations make documenting urinary output simple for medical records, fluid balance calculations, or tracking patient condition changes.

Versatile hanging — Multiple attachment points secure the bag to virtually any bedside setup while maintaining proper below-bladder positioning for gravity drainage.

Professional quality — Medical-grade construction withstands clinical use demands while maintaining clarity for output assessment. Durable yet designed for safe single-use disposal.

How to Use

Initial Setup:

1. Verify sterility — check packaging is intact and undamaged; confirm expiration date
2. Prepare connection — remove bag from packaging using aseptic technique; keep Luer-Lock inlet protected until ready
3. Connect to catheter or extension tubing:
   • Remove protective caps from bag inlet and catheter/tubing outlet
   • Align Luer-Lock threads
   • Twist clockwise until secure (you should feel resistance)
   • Give gentle tug to confirm locked connection
4. Position the bag:
   • Hang below bladder level at all times (critical for gravity drainage)
   • Attach using hanging straps or holes to bedside stand, bedrail, or bed frame
   • Ensure tubing has no kinks or loops that could block flow
   • Route tubing to avoid pressure points on patient
5. Verify proper function — check that urine flows freely; confirm anti-reflux tower functions correctly; ensure outlet valve is closed securely

During Use:

Positioning requirements:

• Always keep bag below bladder level
• Never place bag on bed or at patient's hip/abdomen level
• Reposition below bladder after any patient transfer or movement
• For ambulatory patients, use leg bag during mobility; switch to bedside bag for rest

Monitoring output:

• Check volume using graduated markings
• Document per facility protocol or care plan
• Assess urine color, clarity, and presence of sediment or blood
• Note unusual odor or appearance
• Monitor flow—sudden decrease may indicate blockage

Emptying procedure:

1. Empty when 1/2 to 2/3 full (don't wait until completely full)
2. Perform hand hygiene and don gloves
3. Position measuring container or toilet below outlet valve
4. Hold drain outlet over container without touching the rim
5. Open slide-tap valve with thumb (slides to open position)
6. Allow complete drainage (may take 30-60 seconds for full bag)
7. Close valve securely by sliding back to closed position
8. Wipe outlet with antiseptic wipe if per facility protocol
9. Document output volume if required
10. Remove gloves and perform hand hygiene

Important tips:

• Never let outlet touch the container (maintains closed system integrity)
• Empty regularly to prevent stress on connections
• Close valve completely to prevent leakage
• Single-patient use only to prevent cross-contamination

When to Replace:

Immediate replacement if:

• Bag is damaged, cracked, or leaking
• System has been contaminated
• Luer-Lock connection is damaged or won't secure
• Any component malfunction occurs

Routine replacement:

• Single-use only—dispose after one use period
• Follow facility protocols (daily change, per shift, or per patient discharge)
• Home care: typically replace every 24 hours or per physician order

Disposal:

• Empty completely into toilet or per facility waste protocol
• Disconnect using aseptic technique
• Dispose in appropriate medical waste container
• Perform hand hygiene after disposal

Understanding Anti-Reflux Protection

How anti-reflux towers work:

The integrated tower chamber creates a one-way valve system:

1. Urine flows down from catheter into the tower
2. Tower chamber fills to a certain level
3. Urine overflows from tower into main collection area
4. One-way design prevents urine from flowing backward

Why this matters for infection prevention:

Bacteria multiply rapidly in collected urine. Without anti-reflux protection, patient movement or bag positioning can cause contaminated urine to flow back toward the bladder, introducing bacteria and causing catheter-associated urinary tract infections (CAUTIs). Anti-reflux drainage bags are associated with reduced CAUTI rates in clinical studies and are recommended by CDC guidelines as part of catheter care bundles.

When anti-reflux is especially critical:

• Extended catheterization periods
• Immunocompromised patients
• Post-surgical patients
• Patients with history of UTIs
• Overnight use when monitoring is reduced
• Long-term care facilities with infection prevention protocols

Luer-Lock vs Standard Push-On Connections

Luer-Lock Advantages (This Product):

• Threaded connector twists to lock securely
• Mechanical lock requires intentional twisting to disconnect
• Virtually eliminates accidental disconnects
• Maintains closed system integrity better
• Reduces infection risk and cleanup needs
• Preferred for overnight drainage and active patients

Standard Push-On Limitations:

• Friction fit only with no mechanical lock
• Can accidentally disconnect with patient movement or routine care
• Higher risk of system breaks and infection exposure

Clinical perspective: Many facilities are transitioning to Luer-Lock as standard because infection prevention benefits outweigh the minimal additional connection effort.

Troubleshooting Common Issues

"Urine isn't draining into the bag."

• Check: Is bag below bladder level? Is tubing kinked? Is catheter blocked?
• Solution: Verify positioning, check tubing for obstructions, ensure proper catheter placement

"The Luer-Lock connection keeps leaking."

• Check: Is connection fully threaded? Are threads damaged? Is there debris?
• Solution: Disconnect, inspect threads, clean if needed, reconnect ensuring proper alignment

"The bag leaks from the outlet."

• Check: Is slide-tap valve fully closed? Is outlet damaged?
• Solution: Verify valve position; if damaged, replace bag immediately

"Output is less than expected."

• Consider: Decreased fluid intake? Catheter blockage? Tubing kinked? Patient's condition changing?
• Action: Assess entire system, document decreased output, notify clinician per protocol

"Patient complains of pulling or discomfort."

• Check: Is tubing pulling on catheter? Is bag too heavy? Has position changed?
• Solution: Ensure adequate tubing slack, empty if overfull, reposition for comfort
