Description




TECHNICAL FIELD




This invention relates to an apparatus for bathing body parts, such as the feet or hands.




BACKGROUND ART




Most people experience foot problems at some time in their lives. This is not surprising, considering that many people are employed in jobs that require them to be on their feet all day. In fact, even an average day of walking can exert force equal to several hundred tons of pressure on the feet.




In an attempt to alleviate a variety of podiatric problems, bathing of the feet has become a recognized therapeutic method. For example, soaking soothes the feet and aids in recovery from fatigue. Bathing of the feet also stimulates the circulation of blood therethrough, which results in increased metabolism and excretion. In addition, foot bathing facilitates the removal of painful growths such as calluses, bunions, and corns.




Many types of foot baths have been utilized as therapeutic devices for the feet. Typically, foot baths provide heated water for which the temperature is maintained via electrical means. In addition, current foot baths often provide massage to the feet through vibration of the foot bath. Vibratory massage enhances the therapeutic results achieved with soaking alone by further increasing circulation, as well as relaxing and massaging the muscles.




While heat and vibration applied to the feet in an overall manner is helpful, conventional foot baths are not designed with the capability to target specific areas of the feet. For example, it is common for a user to wish to concentrate treatment to a specific part or parts of his/her feet such as the ball, heel, or arch. Therefore, a need exists for a bath apparatus with the capability to focus heat and/or massage at specific locations of the body. Such a bath apparatus would not only allow users to tailor therapy regimens to their individual needs, but would also increase the speed at which therapy can be accomplished, thereby increasing the convenience for the user.




DISCLOSURE OF INVENTION




Therefore, it is a principal object according to the present invention to provide an apparatus for bathing body parts and providing targeted therapy, including heat and massage, to the body parts.




Accordingly, an apparatus is provided for bathing body parts, such as the feet or hands. The bath apparatus includes a bath chamber for containing fluid, such as water, and receiving the body part therein. The bath chamber includes a bottom surface and a wall structure extending upwardly therefrom, wherein the wall structure has a contact area adapted to be uncovered by fluid contained in the bath chamber. A heating member is provided on the contact area for providing heat to the body part when the body part is placed on the contact area.
