Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an acupressure/massage unit in an apparatus capable of applying massage and acupressure effects to various parts of the human body.

Many mechanical instruments are known to substitute oriental therapeutic techniques known as massage and massaging.

A typical example is a chair-type massaging machine, but the massaging machine used here is a simple mechanical reciprocating motion.
The areas of the body that can be treated are also very limited, such as the shoulders and back muscles.

Moreover, since the massager reciprocates with a constant stroke, it separates from the body each time it reciprocates, causing the recipient's body to shake due to the reaction, resulting in shocking contact and unreasonable pressure. There are many problems such as difficulty in feeling pleasure and damage to capillaries.

There are also chair-type and bed-type pie breaks,
This has a resonant effect on the body and is uncomfortable.

Moreover, the effect of massaging the muscles is not so great.

In this case as well, the treatment area is extremely limited, and no systemic treatment effect can be expected.

Therefore, considering the treatment of the whole body, a handheld type was considered, but almost all of these are vibration type (pie break), and depending on the treatment area, it may cause discomfort to the patient. be.

Moreover, in order to increase the massaging effect, the weight of the device must be increased, which is a fatal flaw for a hand-held type.

In short, these known treatment devices do not provide massaging or massaging effects, but simply provide a pseudo effect.

This invention provides an acupressure/massage unit that can be used as a handheld type that can be applied to any part of the body, or that can have acupressure effects when attached to a bed. That's what you're trying to get.

Hereinafter, the present invention will be specifically explained based on illustrated embodiments.

In the figure, reference numeral 1 denotes a base having palm parts 2, 2 at both ends, and the palm parts 2, 2 are provided with trunnions 3, 3, on which first fingers 4, 4 are respectively attached. It is pivoted.

The first fingers 4, 4 are provided with short arm portions 4a, 4a remote from the pivot portion at their proximal ends, and at this position the first fingers 4, 4 are connected by pins 5, 5. The piston and cylinder mechanism 6 is pivotally connected to the arms 5a and 5b of the hydraulic piston and cylinder mechanism 6.
It is built in between.

The piston/cylinder mechanism 6 connects a cylinder 6e having ports 6c and 6d at both ends to the arm 6a, and a piston 6f that reciprocates within the cylinder 6e.
is connected to the arm 6b, and an all-port type control block 9 is connected to the ports 6c and 6d via hydraulic connections 1 and 8.

This control block 9 is well known in hydraulic systems.
It operates electromagnetically and serves to selectively communicate ports 6c and 6d with pump 10 and hydraulic return tank 11.

An IJ valve 12 is provided in the hydraulic line connecting the block 9 and the pump 10.

Then, by the operation of the piston/cylinder mechanism 6, the first
The fingers 4, 4 can pivot using the trunnions 3, 3 as a first joint.

Each of these first fingers 4, 4 has its tip branched into a plurality of parts, for example, three, and each branch finger part 4b, 4c,
4d, there is a second finger 14 with that as the second joint 13.
a, 14b, 14c are pivotally connected, and in this case, the fingers 14a, 14b, 14C are provided with a stopper 15 to prevent reverse bending, so that the movement of the second joint 13 is prevented. is subject to restrictions.

These branch finger parts 4b, 4c, 4d and finger 14a,
14b and 14c are provided with brackets N6 and 1γ, respectively, and a second hydraulic piston-cylinder mechanism 18 is constructed and pivotally mounted between both brackets.

This piston-cylinder mechanism 18 has a piston 18b fitted into a cylinder 18a, a piston rod 18c protruding outside, and a head of the cylinder 18a and a piston 18b.
It has a single-sided structure with a compression coil spring 19 interposed between the head of the cylinder 18a and the bottom of the cylinder 18a.
Port 18d is open.

The pump 10 and the hydraulic return tank 11 are communicated with this port 18d via a switching valve 20.

Then, by the operation of the piston mechanism 18, the second joint 13
Branch finger parts 4b, 4c, 4d and second finger 14a in
, 14b, 14c.

Further, some of the branching indicator parts 4 b , 4 c t 4 d, for example, branching indicator parts 4 c facing each other.
, 4c incorporates a second piston/cylinder mechanism 21.

That is, this branch finger portion 4c is separated into a base end side and a distal end side, and a cylinder 21a is fixed to the distal end side, and the piston 2lb inserted therein is pushed against the head side of the cylinder 21a by a compression coil spring 22. biased and also cylinder 2
A supply path 23 for supplying pressure oil to the head of the pump 1a is provided, and the supply path 23 is communicated with the pump 10 and the hydraulic pressure return tank 11 via a switching valve 24.

Then, the first finger 4, the second finger 14a, 14b, 1
4c is entirely covered with a sponge body 25 with hydraulic pistons and cylinders inside, and the sponge body 25 is covered with a synthetic resin sheet 26.

In this embodiment, the second fingers 14b of one group are incorporated into the hydraulic system so that the second fingers 14a and 14C of the other group have a common hydraulic circuit.

In such a configuration, in order to massage a suitable part of the body, such as an arm, the control block 9 is first activated to supply pressure oil from port 6c and drain the oil from port 1-6d. As a result, the first fingers 4, 4 move their tips toward each other, and the second fingers 14a, 14b, 14c are in a state where they are sandwiching the arms.

Here, the control block 9 is locked, and in this state, the switching valve 20 is operated to switch the second piston/cylinder mechanism 1.
Add pressure oil to some of 8.

As a result, the second finger 14a, 14c and the second finger 14b on the opposite side are bent inward to apply finger pressure.

At the next moment, the switching valve 20 is switched, the pressure oil is removed from the said several of the second piston-cylinder mechanisms 18, and the above-mentioned fingers are returned by the action of the spring 19, while the remaining piston-cylinder mechanisms Pressure oil is added to 18, and the second
The second finger 14a, 14C on the opposite side of the finger 14b bends inward to apply finger pressure.

In this manner, by switching the switching valve 20, the finger pressure is applied alternately on both sides of the arm, thereby producing a massaging effect.

In this case, the second finger is set to the first finger 4, 4 in advance.
Since the massager is placed in a pinched state, it never leaves your arm, giving you a completely authentic massaging effect and no shocking action.

In addition, when this acupressure/massage unit is fixedly placed on a separate bed or the like, and the affected area is applied to the tips of the second fingers 14b and 14b, and the switching valve 24 is continuously switched, the Since the piston/cylinder mechanism 21 of No. 3 works and the second fingers 14b, 14b are projected longer than the other fingers, an acupressure effect can be obtained.

In this case, when applying pressure oil, the fingertips 14b, 14b slowly push the affected area, and when the oil is drained, the springs 22 quickly return the finger, so that the treatment can be performed with the same feel as in actual acupressure treatment.

As described above, according to the present invention, the first piston-cylinder mechanism positions the second finger with respect to the desired body part, and then the second piston-cylinder mechanism is used to massage the affected area in a pushing manner. In addition, if necessary, the required second finger can be protruded and the acupressure effect can be increased, making it possible to mechanically perform full-scale massaging and fingering treatments that have not been seen before.

Moreover, since this unit is handy, it can be used throughout the body.

In addition, by selecting the setting value of the IJ IJ valve to control the pressure oil, it is possible to avoid overpressure that would cause pain to the patient, and movements such as massaging and acupressure can be performed gently. We can expect the effect that it will be possible to do this.
