Abstract

A device for building up muscle capable of applying a uniform and sufficient pressing force to an extremity to be tightened even if the device is affected by the movement of the muscle, comprising a hollow cuff in which a tube and a restricting plate (6) are installed and a fixing means for maintaining the cuff in a loop shape of a specified diameter. The cuff is wound on the muscle of the extremity at a specified tightening portion, fixed by the fixing means to provide the specified diameter, and a specified pressing force is applied to the extremity on which the cuff is wound by charging air into the tube, whereby obstructing blood flow to build up the muscle of the extremity. Grooves (6a) are formed in the restricting plate (6) so that, when air is charged into the tube, the expansion direction of the tube can be restricted to the side of the cuff facing the muscle when the cuff is wound on the muscle.

Claims5

Dependent claims

A muscle development device comprising:

a hollow tight fitting band having a tube therein;
and
fastening means keeping a length of the tight fitting band in a loop having a desired size,
the muscle development device being used to develop muscles of a limb while restricting the blood flow therethrough by means of applying, with said tight fitting band being rest on muscles of a predetermined compressed range of said limb and said tight fitting band being fastened with said fastening means to have a desired size, a predetermined pressure to said limb around which said tight fitting band is wrapped, the pressure being produced by introducing air to said tube,
said tight fitting band having a limiter plate therein, the limiter plate limiting the direction towards which said tube is allowed to inflate as said tube is filled with air, to against the muscles as determined with said tight fitting band being rest on the muscles,
said limiter plate being adapted to flexibly move in a curve by means of grooves provided in the surface thereof against said tube in a direction not parallel to the lengthwise direction of said tight fitting band at a predetermined distance along the length of said tight fitting band.
