Abstract
Abstract This device is constructed in such a manner that a pump for suction and exhaust of air by an electric motor and a crank is provided with a funnel type cup by means of a detachable hose, and an opening portion of the cup is brought into contact with the part of the human body under pressure airtightly. Massage stimulation is performed by the air suction causing the swollen surface of the body and by the air exhaust (discharge) causing the pressure on the surface of the body. Moreover, the cup is provided with an electric heating illuminant to increase the massage stimulation effect by heated air or an electrode for generating low frequency pulse signal.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
234 words
A massage device comprising: a housing, an electric motor, a reduction gear and a crank all connected in series for rotation in unison, a pump connected to the crank and operable to move air, a delivery tube for conveying air moved by said pump to the exterior of the housing, a hose having one end detachably connected to said delivery tube, a rotary valve assembly connected to said hose in fluid communication therewith, a plurality of branch hoses connected with said valve assembly, drive means including a spring motor operative independently of said electric motor for driving said rotary valve assembly, control means rotatable to a maximum of one revolution to initiate said spring motor and being movable to a selected position to determine the period of time of rotation of said rotary valve assembly, said valve assembly being continuously rotatable during said selected period of time to deliver fluid sequentially to said plurality of branch hoses simultaneously with the movement of air by said pump, a plurality of cups connected to said plurality of branch hoses, respectively, and band means attachable to the body of a person and having notched portions for detachably receiving and holding said cups in selected spaced relationship relative to each other and for locating said cups in a plurality of spaced locations on the body to sequentially apply stimulation to such locations for the predetermined period of time.
