In this type of conventional chair-type pneumatic massage machine, a bag body that expands and contracts due to changes in air pressure can be arranged not only on the backrest portion or the seat portion but also on other portions. Supply and exhaust air to each,
In addition to the waist and back of the human body, a proper pneumatic massage can be applied to the neck, buttocks, thighs, and legs, but it is possible to perform pneumatic massage to the human body, especially to the hand. The current situation is that no special massage machine for local use that can professionally massage such a hand has been developed.

The present invention has been made in view of the above-mentioned problems, and the hand portion and the arm portion are stably placed,
The purpose of the present invention is to provide a massager with a hand-rubbing function that can effectively perform pneumatic treatment on the hands and arms.

[0009]

[Means for Solving the Problems] That is, the massager with a hand massage function of the present invention allows the human body parts to be placed on and removed from the appropriate positions on the upper surfaces of both armrests of the chair body for expansion and contraction treatment. A massager with a hand-rubbing function, in which compressed air supply / exhaust means that can be applied is provided, wherein each armrest portion of the massager is formed on an armrest portion provided with rising walls on both sides in the elbow width direction. The present invention is characterized in that the human hand is stably held on the upper surfaces of both armrests so that the hand can efficiently perform pneumatic treatment.

Further, in the massager with a hand massage function of the present invention, an external power source for driving and stopping the compressed air supply / exhaust means is provided at a position corresponding to the fingertip of the user's hand of the armrest or in the vicinity of the fingertip. The compressed air supply / exhaust means can be easily driven and stopped, and the compressed air supply / exhaust means can be instantaneously stopped in an emergency.

It is possible to efficiently perform moderate and comfortable pneumatic treatment by pressing from the side.

Furthermore, the massager with a hand-rubbing function of the present invention is
Since the expansion and contraction bags arranged on both armrests are composed of an expansion and contraction bag group in which two or more expansion and contraction bags are superposed, the expansion and contraction bags in the expansion and contraction bag group are sequentially and synergistically sandwiched. Thus, it is possible to efficiently perform pneumatic treatment with a feeling of pressure due to the strength of the human hand and arm that cannot be performed by the conventional massage machine.

Further, in the massager with a hand-rubbing function of the present invention, since the treatment protrusions are disposed on the sides of the expansion and contraction bags arranged on the both armrests, which are in contact with the human body, When the human body hand contact side expands, the treatment projection abuts on the hand portion or the arm portion, whereby strong pneumatic treatment can be properly applied.

Further, in the massager with a hand massage function of the present invention, since the vibrating member is arranged at a proper position for vibrating the upper surfaces of the both armrests, the practitioner expands and contracts the expansion and contraction bag and vibrates the vibrating member. By arbitrarily selecting the operation and operating them simultaneously or independently, vibration treatment by the vibrating member and pressure air treatment by the expansion and contraction bag for both the human hand and arm, which cannot be performed by the conventional massage machine, or both of them can be performed. It is possible to properly select and perform the vibration pneumatic treatment.

Further, in the massager with a hand massage function of the present invention, the expansion / contraction bag of the compressed air supply / exhaust means is arranged at an appropriate place on the upper surface of both armrests, and the compressed air supply / discharge device is provided with a rotary valve or the like. The exhaust passage selection switching means is provided, and the control means such as an electronic circuit for controlling the exhaust passage selection switching means may be built in, and the compressed air supply / exhaust device may be configured to supply / exhaust so as to expand / contract appropriately. The user can appropriately select the air supply / exhaust from the air supply / exhaust port, and the order of air supply / exhaust of each expansion / contraction bag can be arbitrarily changed to selectively use the medical treatment desired by the user.
