Why 750 mL Capacity for Extended Wear Freedom

Frequent bathroom trips for leg bag emptying disrupt daily activities, work schedules, and sleep quality. The 750 mL (26 oz) capacity provides up to 50% more volume than standard 500 mL bags, extending time between empties from 2-3 hours to 4-5 hours for moderate output users. This larger reservoir is particularly valuable during meetings, travel, physical activity, or overnight wear when access to facilities is limited. The integrated anti-reflux valve prevents urine backflow toward the catheter—critical during position changes, bending, or lying down—reducing infection risk and maintaining drainage efficiency. The 50 cm kink-resistant inlet tube allows natural leg movement without tube compression that could block flow or create pressure on the bladder.

Key Features

• 750 mL (26 oz) capacity: extended wear between emptying for active lifestyles
• Integrated anti-reflux valve: prevents backflow during movement and position changes
• 50 cm kink-resistant inlet tube: flexible tubing maintains steady drainage during activity
• Soft, adjustable leg straps: secure thigh or calf placement without binding or slipping
• Low-profile outlet tap: one-handed lever or clamp valve for quick, hygienic emptying
• Multilayer odor-barrier film: discreet construction minimizes rustle and odor
• Latex-free, PVC-free, phthalate-free: safe for sensitive skin and long-term use
• Single sterile bag with straps: ready for immediate connection to catheter

Benefits

• Fewer interruptions: longer intervals between emptying support work, travel, and social activities
• Reliable leak prevention: anti-reflux valve and secure connections maintain confidence
• All-day comfort: breathable straps and flexible tubing move naturally with your body
• Discreet wear: low-profile design fits under pants, skirts, or loose clothing without bulk
• Simple maintenance: easy-empty tap allows hygienic drainage without bag removal
• Skin-friendly materials: latex-free construction reduces allergic reactions and irritation

Clinical Applications

✓ Post-surgical catheterization: extended-wear capacity reduces nursing burden during recovery
✓ Chronic retention management: reliable drainage for long-term indwelling catheter users
✓ Active lifestyle users: secure, comfortable option for work, exercise, and social activities
✓ Overnight use: larger capacity accommodates nighttime output without frequent waking
✓ Travel and mobility: extended wear freedom during car trips, flights, or public outings
✓ Rehabilitation settings: supports patient independence during physical therapy sessions

Usage & Application

Initial Setup:

1. Wash hands thoroughly and prepare clean work surface
2. Verify the outlet tap is in the closed position before connection
3. Connect the 50 cm inlet tube to your catheter outlet using a secure, twist-lock connection
4. Gently pull on the connection to confirm it's seated properly
5. Position the drainage bag below bladder level to ensure gravity-assisted flow

Securing the Bag:

1. Choose thigh or calf placement based on comfort and clothing (thigh placement more discreet under pants)
2. Thread the soft straps through the bag's attachment loops
3. Wrap straps around your leg and fasten securely—snug enough to prevent slipping, loose enough to allow two fingers underneath
4. Position the bag on the inner or outer leg depending on preference (inner leg more discreet)
5. Ensure the inlet tube follows a smooth downward path without kinks or loops

Emptying Procedure:

1. Locate a toilet or suitable drainage container
2. Position the outlet tap over the toilet bowl
3. Open the tap by lifting the lever or releasing the clamp (one-handed operation)
4. Allow complete drainage—gently squeeze the bag to express remaining urine
5. Close the tap firmly before moving away from the toilet
6. Wipe the outlet valve with toilet paper or antiseptic wipe to maintain hygiene

Daily Maintenance:

1. Empty the bag when approximately 2/3 full (around 500 mL) to maintain comfort and prevent strain on straps
2. Check the inlet tube connection periodically to ensure no disconnection or leakage
3. Monitor urine color and clarity—report significant changes to healthcare provider
4. Clean the exterior with a damp cloth if soiled

Removal and Disposal:

1. Close the outlet tap and disconnect from catheter over a toilet or container
2. Empty any remaining urine through the outlet tap
3. Remove leg straps and dispose of entire bag according to local medical waste guidelines
4. Replace bag every 5-7 days or per clinician recommendation—sooner if odor or damage develops

Troubleshooting Tips:

• If drainage slows, check for tube kinks between catheter and bag
• If straps cause discomfort, reposition slightly higher or lower on the leg
• For overnight use, consider wearing over loose pajama pants to reduce skin contact time
• If anti-reflux valve clicks audibly, this is normal during position changes
