Why 4000 mL High-Capacity with Anti-Reflux

Overnight and high-output situations require maximum capacity to prevent frequent bag changes that disrupt patient rest and increase infection risk. The 4000 mL volume accommodates extended drainage periods, while the anti-reflux tower provides critical protection against urine backflow—a key factor in preventing catheter-associated urinary tract infections (CAUTIs).

Key Features & Benefits

• 4000 mL high-capacity chamber with easy-read graduations for accurate monitoring
• Anti-reflux tower helps prevent urine backflow toward patient
• Luer-lock inlet provides secure, leak-resistant connection to standard catheters/tubing
• Slide-tap drain valve enables controlled, one-handed emptying
• Large bore tubing with kink resistance ensures consistent flow
• Hanging strap & bed-rail hooks keep bag positioned below bladder
• Sampling/needleless port on tubing for aseptic samples (varies by model)
• Latex-free, sterile single-patient use

Clinical Applications

Appropriate for: ✓ Overnight drainage for bed-bound or immobile patients
✓ High-output post-operative urinary management
✓ Long-term catheterization requiring fewer bag changes
✓ ICU and acute care settings with continuous monitoring
✓ Post-surgical patients with Foley or suprapubic catheters
✓ Extended procedures requiring uninterrupted drainage
✓ Facilities focused on CAUTI prevention protocols

Usage & Application - Clinical Guidance

For Healthcare Professional Use: This drainage bag is intended for use by trained clinicians or under clinical direction following facility protocols.

Setup & Connection:

1. Verify bag is sterile and packaging is intact
2. Remove from package using aseptic technique
3. Connect catheter tubing to bag inlet via Luer-lock connection
4. Twist to secure positive lock engagement
5. Ensure anti-reflux tower is upright and functional
6. Position bag below bladder level using bed-rail hooks or hanger
7. Verify unobstructed flow from catheter to bag

Positioning Requirements:

• ALWAYS keep bag below bladder level to ensure gravity drainage
• Secure to bed frame or IV pole below patient level
• Avoid placing on floor (contamination risk)
• Ensure tubing has no kinks or compression points
• Maintain straight drainage path when possible

Monitoring:

• Check graduations regularly for output measurement
• Document volumes per facility protocol
• Empty when bag reaches ½ to ¾ full (not completely full)
• Monitor for adequate flow and catheter patency
• Inspect anti-reflux tower for proper function

Emptying Procedure:

1. Wash hands and don clean gloves
2. Position receptacle below drain valve (avoid contact)
3. Open slide-tap valve to drain completely
4. Close valve securely when empty
5. Wipe outlet with alcohol prep
6. Dispose of urine per facility protocol
7. Remove gloves and perform hand hygiene

Sampling (if port available):

• Use needleless port for aseptic urine sampling
• Follow facility protocol for specimen collection
• Never disconnect catheter to obtain sample
• Maintain closed system integrity

Infection Prevention:

• Maintain closed drainage system at all times
• Never disconnect unless catheter replacement needed
• Keep bag below bladder level continuously
• Empty regularly to prevent overfilling and backpressure
• Replace entire system per facility protocol (typically with catheter change)
