Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a health care device that utilizes buoyancy and can reduce the unbalance of gravity applied to the body and the contact pressure to the body.

(Conventional technology) In the past, it was common for people, not only the elderly and sick, to sleep on futons or beds to rest their bodies, but they also had functions such as preventing bedsores and reducing contact pressure. For example, as in JP-A-57-139307,
By filling an ice bag with water, when a person stands on it, the body surface and the ice bag exert force on each other over a wider area than before.
A bed with a flexible sheet that allows the patient to easily turn over, as in JP-A-58-94852, in which compressed air is blown from under the bed to fluidize the solid particle medium. There were medical beds that supported patients lying on sheets in a levitating state.

(Problems with the prior art) In the prior art, for example, as in JP-A-57-139307, a method has been devised that attempts to prevent the concentration of contact pressure by attenuating the residual wave motion, which is a drawback peculiar to water beds. However, it has the disadvantage that it breaks more frequently than other beds due to the contact pressure exerted on the ice bag, and that it is almost as difficult to turn over as conventional bedding.

Furthermore, flexible sheets such as those disclosed in JP-A-56-18871 are not designed to disperse the contact pressure applied to the body, so the contact pressure is concentrated on the surface in contact with the body. Patients have difficulty turning over in bed. Especially when the patient is covered with futons or blankets, they have to move them every time they turn over, placing a burden on patients and nurses. Also, the means to reduce contact pressure has not been improved.

If a cushion is provided by compressed air from below as in Japanese Patent Application Laid-Open No. 58-94852, ventilation can be improved and contact pressure can be reduced, but maintenance costs are high. Moreover, ventilation is so good that a temperature control mechanism is sometimes necessary.

As mentioned above, each of the conventional techniques has its own problems.

Furthermore, a common problem with commonly used futons and beds, as well as with the above-mentioned bedding, is that it is difficult for the user to take a posture that projects vertically downward from the bed. For example, even if you want to sleep on all fours, it is difficult to get a good night's sleep. This is because the body's weight is concentrated on each of the four points on the hands and feet, and the muscles and nerves that support it become active to a certain extent, making it difficult to get a good night's sleep. Furthermore, when the temperature is low, a futon or blanket is naturally required on top, but these act as a great pressure and press down on the user from above. For this reason, it is almost impossible for the user to sleep soundly while lying on his back with his knees up.

In other words, it is difficult to sleep in a posture that protrudes vertically downward or vertically upward, and when it comes to moving your arms and legs, you cannot move them sufficiently in the same two-dimensional direction as the expanse of the bed.

This type of pressure in two-dimensional directions seems to be particularly bad for pregnant women, and one of the reasons why pregnant women are able to give birth in a healthy manner by swimming, for example, is that the above-mentioned negative effects can be alleviated to some extent. good. It is generally known that exercise in water, such as swimming, is good for the circulatory system and internal organs and is good for health. However, there has never been anything that fully utilizes these points in bedding.

SUMMARY OF THE INVENTION An object of the present invention is to provide a health care device that solves the problems of the prior art and reduces the burden on the user's body.

(Means to solve the problem) In order to achieve this objective, this invention has the following advantages. flee using such means.

In other words, the buoyancy health care device according to the present invention reduces the burden caused by unbalanced gravitational loads and contact pressure on the body when the body is submerged in liquid, compared to conventional beds and chairs. It has a rotatable opening in the partition wall between the liquid-containing storage part and the outside, and the liquid isolation part is connected to the outside space of the storage part through the opening. By creating an enclosed part with the body,
It is a device that allows the user to rest comfortably by making it impossible for the liquid amount (-1) to enter the non-enclosed part.

(Function) ``The body is placed in a liquid separator, and a part of the body, especially the head, is released outside the separator through an opening, and the body inside the separator breaks through the liquid separator with the liquid content. and receive buoyancy. Since this buoyant force acts on the body with a contact surface that is close to the maximum width, the contact pressure becomes correspondingly smaller.

Moreover, when you turn over, you can freely rotate the 1jJJ OfT.
This can be easily done with H. Furthermore, the body can assume almost any shape that is buoyant and balanced.

(Example) Embodiments of the invention will be described with reference to the drawings.

Embodiment 2, including each of the embodiments, will be specifically described with reference to FIG.

The buoyancy health care device of the first embodiment uses the tank [18] as the storage section "2".
0] must be treated, and it is opened to the outside [3] so that there is no need to remove it from the isolation body [6] every time treatment is performed.

In this example, it is assumed that the separator [6] containing the body-mouth contains saline having a higher specific gravity than the body so that it floats. Further, the partition wall [4] is formed vertically and diagonally so that the head [9] is turned sideways, and the opening [5]
is rotatable. Therefore, the separator [6] is also rotatable. The amount of liquid in tank [18]! An inlet/outlet [26] for the A section is provided. A user enters and exits from the opening [5] into the area [7] surrounded by the separator [6].

By using the above-mentioned device, it is possible to lie down horizontally with respect to the vertical or to take a hunched posture by adjusting the body in the tank [18], and even turn over in bed. It is possible. Since the contact pressure applied to the body [1] is reduced, bedsores are reduced. Since the partition wall [4] is oriented diagonally vertically, even if the height of the head [9] is the same as or lower than the height of the liquid level [21], liquid contents will not enter around the head. It is safe and can be adjusted to the user's preferred posture. Furthermore, the foot being treated can be easily treated. Furthermore, although not shown in the figure, if a temperature control mechanism is provided in the tank [18E], it can be used even more comfortably.

In that case, if the tank walls [19] are made of insulating material, you can save a lot on heating and cooling costs.

Next, a first embodiment will be described with reference to FIG.

FIG. 2 is a diagram of the effect of buoyancy acting on the isolation body [6] covering the body [11].

When the separator [6] covers the body in a shape that matches the body, the buoyant force of the liquid in the liquid content [8], ie, saline in this case, acts in a dispersed manner as shown by the arrow. However, buoyancy [11] is caused by the difference in water pressure between the upper and lower layers of the separator, so it can be said that the upper layer is pulling on the separator, but in this case, the buoyancy acts from vertically downward to upward.
Take the expression. If you use the above-mentioned device, buoyancy [+1] acts as contact pressure on your body.

Therefore, compared to sleeping on a normal bed, you will feel more buoyant [!
I] is dispersed and acts on the upper part and the foot part, so the contact pressure becomes smaller. Therefore, bedsores, blood circulation disorders, and the burden of turning over in bed are reduced.

Second Embodiment Next, a second embodiment will be specifically described with reference to FIG. FIG. 3 is a diagram showing the inside of the storage section [2 tanks 18]. In this example, the member [17] supported by the tank wall [19] instead of the partition wall [4] protrudes into the liquid content [8], and the body [1] is partially supported by buoyancy [11F]. ] is supported at a suitable position by a flat plate.

Using the above-mentioned devices can support the lower back, which is often a good idea when you want to rest your body [1].

The effect of the rotatable opening [5] is the same as that shown in the first embodiment.

By the way, in FIG. 3, the member [17] is supported on the tank wall [+9] by fixing it like a shelf, but there are other ways of supporting it. Although not shown in FIG. 3, it goes without saying that the rigid flat plate may be suspended from the upper tank wall or placed on the bottom of the tank [+8]. Furthermore, the opening [5] is the partition wall [
4], it is rotatable as described in the first embodiment, but since the separator [6] is attached to the opening [5] in a liquid-tight manner, the separator [6] is the opening [5]
It can be rotated as shown by the arrow in Figure 3.

Note that the second embodiment includes the embodiment of claim 8.

Third Embodiment A third embodiment including an embodiment of claim 1 of this invention
An embodiment will be specifically described with reference to FIG. FIG. 4 is a sectional view of the third embodiment in use.

The third embodiment uses a pond [28] as the liquid-containing storage part [2].
] The apparatus of the present invention is provided using the following. In order to release the head [9], which is a part of the body [11], to the outside [3], a partition wall [4] having an opening [5] forms a float part [27], and the partition wall [4 and the insulator [61 forming the enclosed part] are attached in a liquid-tight manner, so that the liquid content [8] floats ffi [27]
It is designed to prevent intrusion inside.

If the float part [27] is provided in this way, the head [9]
It has the effect of allowing freedom of movement, and is sometimes convenient to carry.

<Fourth Embodiment> A fourth embodiment including the embodiment of claim 1 of the present invention will be specifically described with reference to FIG. 5. FIG. 5 is a sectional view of the fourth embodiment in use.

In the fourth embodiment, the device of the present invention is installed using a pond [28]. In order to open the head [9] to the outside [3], a partition wall [4] having an opening t4 [5] is connected to the pond [2].
A stationary enclosure [29] is formed to be placed at the bottom of the enclosure [8], and in this case, pond water, which is the liquid content [8], is prevented from entering the enclosure [29]. By providing the surrounding parts [29] in this way, this device can be installed using the pond [28], so there is no need to build a tank, and the installation can be done at low cost.

Fifth Embodiment> A fifth embodiment including an embodiment of claim 2 of this invention
Examples will be specifically described with reference to FIGS. 6 and 7. FIG. 6 is a partial front view of the fifth embodiment, and FIG. 7 is a side sectional view thereof. The fifth embodiment has a movable wall [30] having an opening [5] in the partition wall [4] of the buoyancy health care device, and one end of a rubber-like sheet [311] is attached to the movable wall [30]. The opening [5] is attached to the partition wall [4] in a liquid-tight manner, and the other end of the sheet is attached to the partition wall [4] in a liquid-tight manner.
4] is movable in the direction of expansion. At this time, in order for the movable wall [30] to move within the range indicated by the arrow in FIG. ing.

According to this device, the user can slightly move the position of the head [9], so the user does not have to feel unnatural when turning over in bed. Further, it is possible to omit fine adjustment of the liquid content [8] in the tank, which further reduces maintenance effort.

In this embodiment, only the case where the movable wall [30] is movable only in the flat direction of the partition wall [4] has been described, but it is also possible with conventional technology to make the movable wall [30] movable in the direction perpendicular to the partition wall [4]. Needless to say, it is.

Sixth Embodiment> A sixth embodiment, including the embodiment of claim 5 of the present invention, will be specifically described with reference to FIG. FIG. 8 is a side sectional view of the sixth embodiment.

In the sixth embodiment, the layer where the separator [6] comes into contact with the body [1] is made of fibrous material 7! to improve ventilation and feel on the skin. ! [
12] will be provided. This fibrous layer [12] may be provided, for example, by stacking several layers of cotton cloth or by using cotton-like synthetic fibers. The central layer has a rubbery layer [!] that is soft enough to isolate liquid contents [8] and not cause discomfort to the body [1]. 3], and liquid inclusions [
8] is provided with a layer of mesh material [14], in this case a mesh fabric, in order to provide sufficient strength. This prevents stuffiness caused by poor ventilation during use, making it soft to the touch.

It has also been reinforced, making it less likely to tear. The layers may be bonded to each other or not, as long as they have sufficient strength and softness.

Seventh Embodiment> A seventh embodiment including an embodiment of claim 6 of this invention is shown in FIGS. This will be explained in detail with reference to Figure 1. FIG. 9 is a partial side sectional view of the seventh embodiment, and FIG.
Figures 1 and 11 are partial side cross-sectional views of an unfavorable implementation.

In the seventh embodiment, the isolator [6] is formed with an appropriate margin for the user's body [l], and has appropriate flexibility and elasticity. A shape with an appropriate margin refers to a shape as described below.

That is, in FIG. 9, the insulator [6] has a sufficient size margin, so that it is large enough to form an air chamber [25] above the vertical horizontal plane of the cross-sectional center of gravity of the body [1]. As a result, the pushing force against the body due to buoyancy is dispersed to every corner, and the contact pressure can be kept small and moderate.

Figure 1O shows a case where the isolator [6] is too large and the material lacks flexibility, so the contact pressure concentrates on the vertically lower part of the body [1] and increases, causing pressure sores. There is. Although not shown in the figure, a similar situation also occurs when the air pressure inside the tank is extremely small compared to the outside air pressure.

FIG. 11 shows a case where the isolator [6] is too flexible and the air chamber [25] cannot move vertically above the body [1] when the user turns over. This causes the center of buoyancy and center of gravity to shift in the vertical and horizontal directions, creating an inversion force that prevents the body from resting.

As described above, according to the seventh embodiment, the buoyant force acts over almost the maximum area, so the contact pressure is reduced, and bedsores are less likely to occur than in the past. Furthermore, when the body [1] rotates, such as when turning over in bed, the isolator [6] does not locally curve to the extent that the air chamber [25] cannot move, and the cross-sectional center of gravity of the body [l] Since the center of buoyancy moves almost vertically upward, turning over can be done smoothly without any reversal force.

In addition, the center of buoyancy refers to the inside of the isolation body [6], including the body [1],
and the center of buoyancy of the ring section of the buoyant force acting on the separator [6].

Eighth Embodiment> An eighth embodiment including the embodiment of claim 9 of the present invention will be specifically described with reference to FIG.

The eighth embodiment has a tank wall [19] so that the tank [18] is airtight.
The tank [18] contains a liquid content [8] and the upper cavity contains air. In order to adjust the amount of air, pressure adjusting means [20] are continuously provided through an air pipe [32] in the upper part of the tank [18]. In this embodiment, compressed air can be sent into and out of the tank [18],
In addition, a compressor capable of reducing the pressure of air shall be used.

By using this device, if some of the air in the tank [18] is removed by a compressor and the pressure is lowered to below atmospheric pressure, the separator [6] becomes taut due to the external pressure. As a result, it is very easy for the user to enter the isolation body [6] because the interior of the isolation body [6] has a large space.

In addition, a larger air chamber [25] is provided between the body [1] and the inside of the separator [6], and the specific gravity relative to the liquid in the tank [I8] becomes larger, making it possible to further obtain buoyancy.

Hereinafter, examples have been shown, but in addition, for example, there are
] Needless to say, if an air conditioning means is provided in which air at an appropriate temperature and humidity can be brought in and out, the body 1'll will be freed from the discomfort of moisture caused by sweat.

Furthermore, it would be better if a wave-dampening mechanism is provided so that when the liquid content [8] generates waves due to the movement of the body [1], the waves can be attenuated. If the user desires pine surge, etc., a sponge or the like may be immersed in the liquid content [8] and stirred to apply appropriate vibrations to the body [1].

Alternatively, even if the opening [5] is not rotatable, the head [
9] When treating, upper needles may be effective.

(Effects of the Invention) By using the buoyancy health care device according to the present invention, the body is stabilized in a state where the gravity applied to the body [1] is mainly balanced by the buoyancy. If the liquid isolator [6] has a bag-like shape, the contact pressure will be more dispersed than in conventional bedding. Since this buoyant force acts on the body [1] with a wider contact surface, the contact pressure can be reduced to almost the minimum. Moreover, when the patient turns over, he or she can easily do so by rotating the isolation body [6] through the rotatable opening [5]. Furthermore, the orientation and posture of the body [11
] Except for the periphery, almost any shape that is in balance with the buoyancy is free, and shapes that spread in any three-dimensional direction can be formed.

Since this device contains liquid, it can reduce heat dissipation into the outside air, and the temperature can be easily adjusted, which may not be necessary depending on the outside temperature. Therefore, it requires less effort to maintain than before, and the cost of use can be reduced accordingly, as well as the burden on patients and nurses.

In addition, since the kake does not require a futon, the burden of pressure on the user in two-dimensional directions is reduced, and conditions can be maintained that are good for health not only for pregnant women but also for the elderly, the sick, and healthy people. If the opening [5] is located in the float part [27], the body parts around the opening [5] and exposed to the outside [3] can be moved more easily.

If the partition wall [4] is movable with the movable wall [30] and the opening [5 parts are movable, the user can move the head part [9 parts, etc.] to the outside [3].
Since the part of the body [1] that is freed up can be moved to some extent, it is possible to turn over and move comfortably without any inconvenience. Further, minute adjustment of the liquid can be further omitted, and maintenance costs can be reduced accordingly.

Parts of the body [1] other than the head [9] are also easily exposed to the outside [
By having the opening [5] so as to be opened to the patient's body, the patient can easily treat the affected area.

The liquid separator [6] has a fibrous layer [12] and a mesh layer [
14], breathability and strength are increased.

Because the liquid separator [6] has an appropriate size with respect to the body [1] and has appropriate elasticity and flexibility, the buoyant force becomes a contact pressure and almost reaches the maximum of the body [1]. Since it acts over a wide range of conditions, the concentration of contact pressure is reduced, and bedsores are also reduced accordingly. In addition, the force of turning over when sleeping is reduced, making it possible to turn over more freely.

If the liquid content inlet/output mechanism [16] is provided, the storage part [2]
Since the liquid content [8] inside can be adjusted, the position of the body [1] relative to the head [9] 1 can be raised or lowered, and if the depth of the liquid content [8] is sufficient, It is possible to take the same position as when sitting, or it is also possible to take a supine position. If a member supported or fixed to the bottom of the storage section [2] or the partition wall [4] is installed to support the body [11] from the outside of the liquid separator [6], the body [11] can be ] It is also possible to take a break.

By providing the tank [18] so that the inside of the tank [18] can be airtight, and by providing the pressure regulating means [20] continuously to the tank [18], the pressure inside the tank can be lowered compared to atmospheric pressure. As a result, the inside of the isolator [6] becomes tense due to the external pressure. Therefore, it is very easy for the user to enter and exit the separator [6]. Also, the body [! ]
By further enlarging the air chamber [25] between the tank and the inside of the separator [6], the specific gravity of the liquid in the tank can be increased.
The buoyancy can be increased accordingly.
