Abstract
Description
- 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.
- Heretofore, various types of massaging devices have been proposed in one of which 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.
- The conventional device for air-massage, however, 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.
- Further, when a muscle of the diseased part becomes tense and stiff causing extremely bad flow of blood and lymph, a simple press and release of the diseased part may afford instantaneous comfort but not sufficient massage-effect.
- The inventor has now found out that 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.
- As the result of further diligent study for developing an air-massage device having a change-over valve mechanism which eliminates all the disadvantages of the conventional air-massage devices described hereinbefore and readily produces a variety of massage effects in spite of its simple construction, the inventor has now improved a device for air-massage containing a rotatable change-over valve mechanism capable of ensuring communication of any one of the air-feeding and exhausting ports with an air-feeding means. The improvement resides in that the change-over valve mechanism is provided with a set of distributing plates having two or three air-feeding and exhausting ports or channnels circumferentially spaced apart equiangularly, for example at about 120°, the distributing plates are fitted concentrically with rotators each having bored passages which allow the air-feeding and exhausting ports of the distributing plates to communicate selectively with the air-feeding means or air-exhausting means, and the rotators are driven simultaneously to rotate by a motor. Thus, an air is fed to one of air-inflatable bags through one of rotators while air is exhausted from other one of inflatable bags through another rotator, producing a variety of massage treatment and its effect.
- Another type of device for medical treatment employing various elastic elements is also known in order to obtain the desired physical effects similar to those of finger-pressure therapy and the acupuncture. The devices of this type, however, has been designed to treat a local site of a human body and may not be employed for a general use. Even if such a device is employed for massage, it is too difficult to obtain a good massage effect making the stream of blood and lymph better.
- The inventor has also developed an efficient and economical air-massage device which utilizes an elastic element having a conventional medical effect, thereby to allow the reduction of an air quantity fed into the air inflatable bag so that a small type of air-feeding and exhausting unit with a less capacity of a compressor may be employed.
- Namely, it has been found out that a comfortable massage effect may be achieved by a device which combines an elastic contacting element for a direct massage action to a body portion with an air inflatable bag for inflation and deflation with a compressed air, and is wound around a body portion such as a diseased site for feeding and exhausting air in relation to the bag. Thus, the elastic element comes into an even contact with the body portion and makes the massage effect uniform and comfortable.
- Further, it has been found out that the attached equipments of the device may become smaller because the higher massage effect may be obtained with a less capacity of the bag using a less volume of the air.
- The elastic element of the device may be constructed as another air bag which is optionally filled with an adjustable volume of air. Preferably, the elastic element is provided with a tongued and grooved face on a surface in contact with a body portion for enhancement of a massage effect. In this case, the element may be made of an elastic material such as rubber or the like. Alternatively, the elastic element may be made of an elastic plate provided with a plurality of projections on the surface in contact with the body portion.
- Further alternative is to provide the elastic element with a plurality of independent air-filled projections on the surface.
- Accordingly, a general object of the invention is to provide a device for air-massage having a change-over valve mechanism, which achieves smooth operation and a variety of air-feeding and exhausting operations for a bag assembly combining a plurality of air inflatable bags, in spite of its simple construction.
- A principal object of the invention is to provide a device for air-massage which comprises a plurality of associated air inflatable bags each having its own port for air-feeding and exhausting, a change-over valve mechanism connected to the bags for air-feeding and exhausting in relation to each bag and air-feeding and exhausting means attached to the change-over valve mechanism, said bags being contacted with a given body portion and being moved sequentially in a wavy manner through an operation of said change-over valve mechanism for massaging an outer body surface.

Further, theair bag 26 used as the elastic element is provided with anair port 30 for adjustment of the air volume so as to control elasticity of theelastic bag element 26. - In accordance with the air inflatable bag thus constructed, the
elastic element 26 in contact with the body portion is independently arranged in relation to thebag 12 movable with the air pressure, so that uniform movement throughout theelastic element 26 is obtained, effecting the even massage action on the body portion contacted with the bag. Moreover, in accordance with the invention the role of thebag 12 is only to put air-pressure indirectly onto theelastic element 26 for movement of the latter, so that the total volume inside thebag 12 may be extremely reduced and that the volume of the air used becomes very small. As a result, a compact type of air- compressor may be employed for air feeding. - Figure 6 shows the device according to the invention, in which a plurality of the air
inflatable bags 12 are combined with the singleelastic element 26. Thus, in this embodiment thebags 12 are provided with theirown ports 22 for the air-tubes 24 which are connected to the air source through a change-over valve mechanism 14 (see Figure 1), so that the time difference may be given between the adjacent bags and the wavy movement of theelastic element 26 may be obtained, resulting in the higher massage effect.
