Abstract

PROBLEM TO BE SOLVED: To improve massaging efficiency by repeating a cycle in which compressed air is continuously supplied into bag bodies from the end side to the center to swell the bag bodies and the compressed air is exhausted at a time. SOLUTION: A bag body 8 is wound around a foot from the ankle to the whole foot, and is fastened using a belt fastener. An appropriate pressure is set using a pressure adjusting device 3, and a drive switch is turned on to actuate a compressor 1. This sends compressed air to an air distributor 4. The air distributor 4 distributes the supplied compressed air as is into distribution grooves passing through each bag body 9 of the bag body 8. By the rotation of a rotary member 11, compressed air is continuously supplied into the bag body 8 from an end side 9 to a center 9 to swell the bag body 8. Then, the compressed air is exhausted at a time from the bag body 9 being pressed. This cycle is repeated to perform a pressure massage. To a hose adaptor 7, a pair of bag body 8 or one bag body 8 is selectively connected.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pneumatic massage device for inflating and deflating a bag body by compressed air to massage a pressured portion of a body such as a lower limb or an upper limb.

[0002]

2. Description of the Related Art Conventionally, an inflatable bag for compression is attached to a body such as a lower limb or an upper limb, and compressed air is supplied to the bag to inflate and squeeze the portion to be compressed. Pneumatic massagers designed to promote blood circulation are already known. This type of massager uses a kneading method in which compressed air is sent to a bag body in which a plurality of bag parts are connected in series to repeat expansion and contraction to pressurize a pressed portion, and a bag body composed of one bag part There is a method in which compressed air is supplied to press the pressed portion at once.

In the case of the former kneading method, compressed air is supplied to a plurality of bag parts provided in the bag body in the form of knots of bamboo, and expansion and contraction are repeated to sequentially inject and deaerate from the periphery. Since the function of pressing the pressured portion and pushing out the venous blood and the like in the meantime toward the center is continuously performed, the blood of the pressured portion is promoted to flow back to the center. In the latter method as well, since the pressure receiving portion is pressed, blood circulation is promoted accordingly.

[0004]

However, according to the former method, when the portion to be pressured is pressed, a force that pushes it toward the center and at the same time flows back toward the periphery is also exerted. That is, in this case, even if the bags are sequentially filled with air, the air bag on the peripheral side is not degassed and is in a compressed state. Therefore, even if the predetermined compression bags located on the central side are sequentially inflated, It has been confirmed that the flow partially flows back to the peripheral side, and blood on the peripheral side cannot be reliably returned to the central side.

On the other hand, according to the latter method, in the case where the entire air chamber is a single air chamber, when the air chamber starts to be filled with air, pressure is applied from a position where the space between the pressure receiving portion and the bag is small, and finally the air receiving chamber is closed. The pressure is applied to the smallest diameter portion of the pressure portion. In the human body, this generally means that the region near the center is thicker and tends to become thinner toward the periphery, so that the compression part moves from the center to the periphery and reverses the physiological blood flow. It is also confirmed to do.

The present invention has been developed as a result of intensive studies in view of the above-mentioned reasons and actual circumstances. The object of the present invention is to supply pressurized air sequentially from the periphery toward the center to each bag portion. The object of the present invention is to provide a pneumatic massage device capable of obtaining an extremely efficient massage effect by evacuating the venous blood or the like in a pressured part only toward the center by exhausting the gas in a constant cycle. .

The effect of is similar to this example. In addition, in the example of wearing the lower limb, which is the above example, the lower limb X and the waist are separately fitted with bags, and if the number of compressed air distributions is 12, for example, 10 bags are attached to the foot. When the remaining compressed air is distributed to the bag attached to the waist, the massage can be sequentially performed from the foot to the waist. In this case, Also exhibits the same effect as this example.

Next, the operation of the above embodiment will be described. First, the bag body 8 is wound around the entire area from the ankle to the foot, and fixed at appropriate positions via the velvet fasteners 8g to 8i. Then, when the pressure is adjusted to an appropriate pressure (for example, 20 to 80 mmHg) by the pressure regulator 3 and the drive switch is turned on, the compressed air generation supply source (compressor) 1 is activated and the compressed air is distributed through the connection pipe. It is delivered to the container 4.

The air distributor 4 starts from the state shown in FIG. 12, and is first distributed from the supply groove 10b through the communication groove 11b to the distribution holes 10c, ... And the bag shown in FIG. It is supplied to the connection plug 8-1 of the body 8 to be in a pressurized state. Next, when the rotating member 11 is sequentially rotated as shown by the arrow in FIG. 12, the distribution holes (1 to 12) are sequentially distributed to the distribution holes (1 to 12) in the pressurized state via the communication groove 11b.
The state shown in is shown.

Further, when the rotary member 11 rotates, the communication groove 11a communicates with the exhaust hole 10d, and at the same time the communication groove 11b communicates with the exhaust hole 10f. Since this exhausted state is maintained by the exhaust groove 10e as the rotor rotates, compression massage is performed in one cycle (30 seconds in this example), and compressed air is supplied and exhausted in the next one cycle. It is carried out sequentially. In addition, the hose adapter 7 can be selected when connecting to the pair of bags 8 or when connecting to one bag 8. When using one bag 8,
When the plug portions of the blind plug member shown in FIG. 23 are attached to the two steps on the left side in FIG. 22, the outlet connection portions (1) to (1) in FIG.
It suffices to connect the connection hose 7B to (12), and when the pair of bags 8 is used, 24 of the hose adapters 7 may be used.

In this way, the compressed air is distributed by the air distributor 4 to 12 flow paths in this embodiment, and as shown in FIG. 8, the bag 9 on the peripheral side to the bag 9 on the central side of the bag 8. Compressed air is sequentially supplied toward each bag 9 to inflate, and then the pressurized air in each bag 9 is exhausted at one time. By repeating this cycle, venous blood in the pressured part of the foot is peripherally removed. Efficiently massage while refluxing from the side to the center.

[0030]

As is apparent from the above description, according to the present invention, when pressurized air is sequentially supplied from the periphery toward the center to each bag portion and exhausted in a certain cycle, venous blood in the pressured portion, etc. It is possible to provide a pneumatic massage device that recirculates only toward the center and obtains an extremely efficient massage effect.

Moreover, when the massage device of the present invention is used, recovery from fatigue and blood circulation can be improved, muscle fatigue can be relieved, and neuralgia and muscle pain can be relieved. It is extremely valuable as a device.
