Description
The Welch Allyn One Tube Inflation Bag is a large adult inflation bag with one tube, the replaceable bladder that sits inside a blood pressure cuff. It suits facilities that rebuild cuffs in house when the bag fails but the cuff sleeve is still sound.
- Large Adult Size – the bag is sized for large adult arms and the cuffs built around them
- One Tube Design – a single tube carries both inflation and sensing on one tube systems
- Non-Conductive Build – the bag is non-conductive, as specified for use around monitoring equipment
The Bladder Inside the Cuff, Replaced on Its Own
When a cuff stops holding pressure, the failure is usually the inner bag, not the outer sleeve. This large adult inflation bag replaces that bladder in a one tube cuff, restoring even inflation across the arm. Its non-conductive build matches the specification Welch Allyn sets for bags used alongside patient monitoring equipment. Rebuilding a cuff with a fresh bag costs a fraction of a complete cuff and keeps a matched size on the shelf. Biomed and supply teams keep bags in the common sizes because cuff failures rarely announce themselves ahead of a clinic day.

Why Replace the Bag Instead of the Whole Cuff
A cuff is a sleeve, closures and a bag, and only the bag handles air pressure cycle after cycle. This genuine bag brings a leaking large adult cuff back to specification for the price of the part that actually failed.
- Targeted Repair – only the failed component is replaced, not the whole cuff assembly
- Correct Specification – non-conductive construction matches the manufacturer's requirement for these cuffs
- Size Matched – the large adult bag restores even compression on larger arms

How do I know the bag is the problem?
