A perished or leaking bulb makes a manual sphygmomanometer unusable, because the cuff will not hold pressure long enough for a controlled deflation. This is the replacement rubber bulb unit for the A&D UM-102 mercury free sphygmomanometer, supplied as a complete bulb and valve assembly.
Swapping the bulb keeps a clinic’s existing units in service and avoids revalidating a new instrument. It fits both the A type and the B type UM-102.
