(1) Field of the Invention
The present invention relates to an exerciser, and more particularly, to an adjustable sphincter exerciser (Kegel exercise) that adjustably trains the sphincter and the user is acknowledged the progress of the training.
(2) Description of the Prior Art
A conventional exerciser for training the sphincter generally includes a knob device which adjusts the distance between a flexible plate and a metal block. The user controls the sphincter to make the flexible plate and the metal block be in contact with each other so as to activate the vibration device to acknowledge the user. The required force can be adjustable according to specific conditions of individual users. The required force can be set so that the user can exercise the sphincter to approach the pre-set standard. Although the restriction of the sphincter is maintained within a pre-set range, the muscular strength and the muscular endurance can be trained. Therefore, adding sleeves of different hardness to the tubular body of the exerciser can achieve the purpose to exercise the muscular strength and the muscular endurance of the sphincter. The adjustment of the distance between the flexible plate and the metal block cannot be increased unlimited, so that for the users who use the conventional sphincter exerciser, they cannot know the progress of the muscular strength and the muscular endurance.
The present invention intends to provide an adjustable sphincter exerciser (Kegel exercise) which improves the shortcomings of the conventional sphincter exerciser.
