ABSTRACT:
A tubular bladder has an outside wall connected to an inside surface of a finger passage through a band of a finger ring. An inside wall of the bladder is integral with the outside wall and forms a gas chamber. A passage connects the gas chamber to a source of air. Increasing air in the gas chamber reduces the diameter of the finger passage. Reducing the quantity of air in the gas chamber increases the diameter of the finger passage. A valve can be provided to meter air into and out of the bladder. If the bladder is resilient and tends to expand the area of the gas chamber, an air passage can let air into and out of the bladder.
