Abstract

PURPOSE:To provide a health bed which enables restoring from fatigue while tuning up physical condition by improving blood circulation and applying moderate motions to internal organs with physical organization at rest during reposing or sleeping. CONSTITUTION:A bed which allows a human body to be inclined gently and slowly or returned to the original position during reposing or sleeping is made up of the body 1 of a bed and a device 4 or a rotating device for moving it vertically to incline. A changeover switch having a timer built thereinto or a number of revolutions adjustor of a motor is connected to the vertically moving device 4 or the rotating device to repeat inclination automatically more than five times per hour and at the frequency of 1,200 or less. In this manner, the inclination of the body is repeated during reposing or sleeping in the bed to feed blood in a vein by a dead load and by the action of a pump utilizing a check valve in the vein while moderate motions are applied to internal organs thereby enabling to obtain the effect on restoring from fatigue by the promotion of blood circulation and effect on tuning up physical condition.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is one of health appliances used to recover fatigue and maintain health.

[0002]

2. Description of the Related Art It is well known that by improving blood circulation, peripheral tissues are activated to recover fatigue and maintain health. There are many devices available for this purpose. Typical examples are vibrator-type massage devices, those that stimulate tissue by using electromagnetic waves and increase the internal temperature of tissue, and electrical stimulation is applied to muscles to promote blood circulation by exercise due to muscle spasms. There are measuring instruments and automatic massage machines that perform mechanical massage. All of these methods are intended to promote blood circulation by applying mechanical, electrical, or magnetic stimulation to the tissue, and all of these methods are indirect methods, such as stiff shoulders to improve local blood circulation. The local ones have some effect, but they are not sufficient for the overall recovery from fatigue.

[0006] Also, there are beds in which raising and lowering are repeated in the same manner as in the present invention, but all of these are for raising and lowering the body in a horizontal state, and for imparting exercise to the body at a high speed. Therefore, although the blood circulation is promoted by exercise, the load on the body is large and the blood circulation is not promoted in a quiet rest state.

[0004]

SUMMARY OF THE INVENTION It is an object of the present invention to improve blood circulation and remove waste products from peripheral tissues of the body to recover fatigue and maintain health. This is the same as the purpose of the prior art, but the present invention is a state in which the peripheral tissues of the body are resting without giving a load to the peripheral tissues of the body such as irritation or spasm. To improve blood circulation, and in addition, the internal functions become inactive like in the elderly, and local nutritional insufficiency to the tissues of the body, which is thought to occur because the number of times of rolling over, decreases. Improves and activates the tissue. It is also intended to be used steadily by elderly people and people with weak physical conditions.

[0005]

In order to solve the above-mentioned problems, the present invention is based on the principle of the natural flow of a fluid, and the relationship between the position of the heart and the position of the part of the body where blood circulation is promoted is cycled. It moves vertically up and down alternately, allowing blood to flow directly by gravity and the pumping action of the check valve in the venous blood vessel. Also, gravity can give an appropriate movement directly to the internal organs. It is a target.

[0006] Generally, the heart acts as a pump for pumping blood by applying pressure to the blood and flowing through the artery, so that blood can be sent against gravity such as blood flow to the head. In addition, even when the direction of gravity such as the direction of the foot is the same as the direction of gravity, the amount of blood is adjusted to flow. On the other hand, the heart has the power to suck blood in the vicinity of the heart, but does not have the power to suck blood in peripheral tissues and veins of the body. These blood moves back toward the heart by the movement of the check valve in the blood vessel and the movement of the body that accompanies the movement of the body. The present invention makes good use of such body function and blood vessel function,
By tilting the bed, the parts of the legs, head, back, etc. that are distant from the heart and tend to have poor blood circulation, are raised above the position of the heart, and the blood in peripheral tissues and veins in that part is directly gravitated by the heart. The blood in the artery is easily spread to the peripheral tissues by returning to the original direction and then returning to the original position. By repeating this operation periodically, blood circulation is promoted and at the same time an appropriate movement is given to the internal organs for activation.

In the present invention, the circulation of blood is promoted by utilizing gravity or the like, and therefore, the position of the part of the body for improving the blood flow must be at least higher than the position of the heart. I won't. However, the lowered position does not necessarily have to be below the position of the heart. Of course, it can be expected that the effect of enhancing the effect by lowering the position of the heart, such as the hands and feet, far from the heart, is not a necessary condition.
In particular, it is preferable that the head is located slightly above the position of the heart. Further, it is not necessary that the repetition cycle of the inclination be the same interval, and it is preferable to change it according to the situation such that the time in the raised state is short and the time in the lowered state is long. The number of times the tilt is repeated is 5 times or more and 1200 times or less per hour as claimed in the claims. The limit of this frequency is not very strict, but as a result of measuring the state of blood flow, it takes about 2 to 5 seconds for blood to be supplied to peripheral tissues, and the blood is supplied to the veins with the body part raised. Since it takes about 1 to 3 seconds for the blood to flow off, the minimum time for supplying and discharging the blood is 3 seconds. Therefore, the maximum number of tilt repetitions is 1200 times per hour. It is possible to reduce the angle of inclination and increase the number of times, but this area is the same as the method of stimulating the tissue such as a vibrator, and furthermore, the stimulation to the body is strong, giving sufficient rest to the tissue. However, this is different from the object of the present invention, which is to improve blood circulation and recover fatigue. Further, the minimum value is related to the number of times a person rolls over during sleep. The number of times is different depending on the person and decreases as the age increases, but it is generally about 5 times per hour, and below this, the effect of the present invention decreases. The number of repetitions of the inclination does not have to be constant at all times, and various methods are possible, such as increasing the number of times in the initial stage of sleep, reducing the number of times in the middle, and increasing the number of times gradually before waking.

As described above, the present invention is a bed used for improving blood circulation during rest, particularly during sleep, and for giving proper movement to the internal organs to improve the physical condition. This bed inclines in only one side as defined in claim 1, and the ones defined in claim 3 and in claim 2 that do not have a fulcrum in the middle, and inclines in both directions, or Some have fulcrums in the middle and the parts on both sides of the bed incline independently. This bed will be briefly described using the attached figures. FIG. 1 shows a bed as defined in claim 1, which has a fulcrum (2) at one end of the bed (1) and a lifting / lowering machine (4) at the other end, and a timer is incorporated in the lifting and lowering machine. It is a device to which the tilt switch defined in the claims is automatically repeated by repeating the raising and lowering by being connected to a switch or a rotation speed controller of the motor. FIG. 2 has one fulcrum in the middle of what is defined in claim 2. With lifting and lowering machines (4) at both ends, both beds can each repeat their own tilt. In FIG. 3, a shaft (5) is fixed to the middle part of the bed, and this shaft is placed on the support base (3) and serves as a fulcrum. A rotating machine (6) is attached to this shaft, and the bed is tilted by giving rotation to the shaft by this rotating machine. The raising and lowering machine and the rotating machine used to repeat the tilt of the health bed of the present invention are not special ones, and known machines are used. Examples of lifting and lowering machines include those using a screw mechanism such as a screw jack, those using a hydraulic or pneumatic cylinder to move up and down, and those utilizing a rotating mechanism using a cam or crank. As a rotating machine, a combination of screw mechanism and forward / reverse rotation of the motor is used.
There is one using reciprocating motion by a hydraulic, pneumatic cylinder or crank mechanism. In either case, a switch is connected to a motor or a hydraulic or pneumatic pump, and a switch incorporating a timer or a rotation speed adjuster of the motor is used to repeatedly incline the bed.

[0009]

By repeating the inclination in the bed of the present invention, the body part automatically repeats the vertical movement during rest or sleep. This vertical movement can be adjusted in rotation speed and height with a timer or a rotation speed adjuster of a motor, and depending on the model, it can be adjusted to a suitable rotation speed and height for each body part. is there.
As a result, when the body part is raised, blood in the peripheral tissues and veins of this part is gravity-flowed toward the heart, and when lowered, the blood is easily supplied from the artery. At this time, the blood in the vein is not returned by the check valve in the vein. This gravity and pumping action by the check valve in the vein improve the blood flow, and also give the internal organs an appropriate movement. This blood circulation accelerating action is performed in a state where the body is slowly resting without imposing a burden on the body.

【Example】

[Example 1] A bed (length 2 m) shown in Fig. 1 was used to sleep for 7 hours with the head coming to the person who had the lifting machine. The height of lifting and lowering was 30 cm (tilt angle 30/200), and the tilt was repeated 120 times per hour. As a result, he was able to sleep well, had the effect of recovering from fatigue, and had no local pressure due to insufficient turning over.

[Embodiment 2] A bed (length 2 m) having a single fulcrum in the middle of the bed defined in claim 2 shown in FIG. 15c
Adjust to m (tilt angle 15/100) and 120 per hour
Repeatedly inclining twice, adjusting the person who came to the foot at a height of 300 m to repeat inclining 360 times per hour, and took a rest for 2 hours. As a result, I had a very comfortable rest,
Moreover, the effect of fatigue recovery was observed. In particular, the effect of relieving foot fatigue was great.

[0011]

EFFECTS OF THE INVENTION By using the apparatus of the present invention, by gently and slowly repeating the leaning on the body during rest or sleep,
The blood circulation can be promoted, and local blood circulation failure caused by less rolling over can be eliminated, and it is also effective in improving the physical condition by giving an appropriate movement to the internal organs. Due to this effect, fatigue recovery during sleep is great, and it is also very effective in relieving swelling that appears especially when extremely tired.
