Definitions

  • This invention relates to a device for air-massage in which a plurality of air inflatable bags each having air-feeding and exhausting ports are arranged and a compressed air is fed to and exhausted from each bag for producing varied movements to have an efficient massage effect on an outer body surface.
  • an air inflatable bag made of a flexible material such as rubber is wound around a body portion such as an arm or a leg and the bag is inflated and deflated with a compressed air to apply and release pressure on a blood vessel, thereby to facilitate a circulation of blood (mainly venous blood and lymph) for massage.
  • blood mainly venous blood and lymph
  • the conventional device for air-massage has such the disadvantages that the air bag is inflated into a cylindrical form when filled with the air, so that an arched surface of the bag comes into uneven contact with the body portion. As a result, a pressure is localized with a minimum stimulus to give uncomfortable feeling to the body portion. In other words, over all even contact of the inflated bag with the body portion is difficult to obtain, so that a satisfactory massage effect may not be achieved.
  • a good massage effect may be obtained by an assembly comprising a plurality of air inflatable bags to which air is alternately fed or exhausted for giving a variety to the pressing or releasing positions on a blood vessel of the diseased part, and a suitable change-over valve mechanism connected to air-feeding means for continuous air-feeding and exhausting operations.
