Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a pinerest that utilizes fluid pressure and is used as bedding for sleeping soundly, preventing bedsores, etc.

[Conventional technology]

BACKGROUND OF THE INVENTION Various types of bedding have been devised to prevent bedsores, provide a good night's sleep, and the like, in which fluid is contained in bag-like cells and the pressure of the fluid supports the load of the person lying on the cells. As one of these, the inventors of the present invention have previously proposed a method that aims to ``actively create a restful sleep'' by giving moderate exercise and a sense of relaxation to people lying down (Jetgansho). 63−
(See No. 108252). The outline is shown in Figures 10 and 11.
This will be explained based on the diagram. FIG. 10 is a side view showing the structure and function, and FIG. 11 is a front view showing the structure and function. On top of the rectangular sheet 7, a plurality of first plates are formed which have an approximately truncated conical shape when pressurized with fluid.
Bag-shaped cells C ₁ are arranged along the sheet 7 with their tops facing leftward, and similar pocket-shaped cells C ₂ are arranged alternately with C ₁ with their tops facing right. By supplying and discharging fluid to and from the bag-shaped cells C ₁ and C ₂ at a predetermined period with the addition of a "1/fluctuation" characteristic, the mat has an inclination or a "1/fluctuation" characteristic as shown in FIG. A rolling motion similar to rolling over is given to a recumbent person at a period having a "1/fluctuation" characteristic.
In this way, the area of pressure applied to the lying person is changed, peripheral blood circulation is promoted, and a feeling of relaxation is created, thereby preventing bedsores and promoting sound sleep.

Note that "1/fluctuation" is a state in which, in a certain time-series signal, the relationship between the frequency constituting the signal and the energy E belonging to it is E∝1/. Since various repeated signals and signal voltage characteristics within our bodies have "1/fluctuation" characteristics, humans tend to feel "pleasure" from stimuli that cause "1/fluctuation" from the outside. There is.

[The problem that the idea attempts to solve]

As explained above, conventional mats have the effect of creating a good night's sleep by giving moderate exercise and a sense of relaxation to people who are lying down, but when used for a long time, they can cause sweating, temperature rise, etc. It is still difficult to say that this is sufficient from the viewpoint of preventing "stuffiness".

The present invention was developed in consideration of these points, and not only creates a moderate amount of exercise and a sense of relaxation by changing the shape of the bag-like cells that form the mat, but also has a function to prevent "stuffiness" during long-term use. In addition, the aim is to provide a pinerest that creates an even more comfortable sleep.

[Means to solve the problem]

The present invention takes the following measures to solve the above problems.

That is, as a pine tress, when pressurized with a fluid, a plurality of first bag-like cells form a substantially truncated conical shape, have a plurality of micropores on the surface, and have their tops facing left; Similarly, second bag-shaped cells are formed in a substantially truncated conical shape, have a plurality of micropores on their surfaces, have their tops facing right, and are arranged alternately with the first bag-shaped cells; means provided in each of the bag-like cells for opening and closing the micropores according to the pressure within the bag-like cells; and a first supply means for supplying and discharging fluid to and from the first bag-like cells; , a second supply means for supplying and discharging fluid to and from the second bag-shaped cell, and an arithmetic and control device that sends signals to the first and second supply means, and the arithmetic and control device is configured to supply and discharge fluid to and from the second bag-shaped cell. The first supply means and the second supply means are made to alternately supply and discharge fluid at a predetermined period.

[Operation] By the above means, two
When fluid is alternately supplied and discharged from the bag cells of the system at a predetermined period, for example T, by the first supply means and the second supply means, the pressure area of the recumbent person is compressed by the truncated conical shape of the bag cells. For example, it changes periodically from the left side to the right side, and then from the right side to the left side.

Further, a plurality of micropores on the surfaces of the first and second bag-like cells are opened and closed according to the internal pressure of the bag-like cells, and the fluid is periodically jetted out.

Therefore, the person lying on the bed is given a rolling motion similar to rolling over, and the fluid flows out to provide a drying effect. In this way, it is possible to prevent bedsores by promoting peripheral blood circulation and to promote sound sleep by preventing "stuffiness".

Furthermore, if the cycle of supplying and discharging fluid to the first and second bag-like cells has, for example, a "1/fluctuation" characteristic, it is possible for a person lying on a side to lie down with a "1/fluctuation" characteristic. A similar rolling motion is given.

In this way, rolling motion occurs in the same way as the rhythm of the body, and at the same time, it prevents stuffiness during long-term use, which promotes peripheral blood circulation, prevents bedsores, prevents stuffiness, and creates a ``feeling of relaxation.'' This will help promote sleep.

An embodiment of the present invention will be described with reference to FIGS. 1 to 9.

FIG. 1 is a plan view of the pinerest portion of the same embodiment, FIG. 2 is a sectional view taken from FIG. 1, FIG. 3 is a front view of FIG. 1, and FIG. 2, FIG. 5 is a perspective view of FIG. 4, FIGS. 6 and 7 are action explanatory diagrams, FIG. 8 is a block diagram of the overall configuration, and FIG.
Figures a, b, c, and d are explanatory diagrams of the action of the pinerest portion.

In FIG. 1, when a rectangular sheet 7 is pressurized with fluid, a plurality of first bag-shaped cells 1 having an approximately truncated cone shape are formed along the long sides of the sheet 7 with the tops facing left. Arranged. Furthermore, each bag-like cell 1 is connected to a first supply and discharge pipe 5 via an end port 3. Similarly, the second pouch-like cells 2 are arranged with their tops facing to the right and with their sides alternately in contact with the first pouch-like cells 1,
It is connected via the port 4 to a second supply and discharge pipe 6 .
As shown in FIGS. 4 and 5, each bag-shaped cell 1, 2 has a plurality of micropores 15 along the upper generatrix direction. Further, on the inner surface, a sheet 14 having one longitudinal side in a rectangular wave shape and the other longitudinal side in a linear shape is provided so that the surface is almost in contact with the inner surface of the bag-shaped cell and the longitudinal sides are overlapped. Also, at this time, the overlapping part is applied so that the microhole 15 is placed in the notch S of the rectangular waveform with a height r, and the straight side is set from the inside with an overlapping margin l of a predetermined length. It is installed so that it is heavy and heavy. The sheet 14 has a predetermined elasticity that maintains a substantially circular shape (cross section), and its elongation is due to the bag-like cells 1 and 2.
With less material, in the area close to the rectangular corrugated part,
It is adhered to the bag-shaped cells 1 and 2 in a predetermined pattern.
The first supply means, the second supply means, and the arithmetic processing device are constructed as shown in FIG. The first supply means, that is, the first pump 11 is connected to each bag-shaped cell 1 on the right side through a first on-off valve 10 and a first supply/discharge pipe 5 . Furthermore, the first pump 11 and the first on-off valve 10
receives a signal from the arithmetic and control unit 8. Further, the second supply means, that is, the second pump 13 is connected to the second on-off valve 12.
It is connected to each bag-shaped cell 2 on the left via a second supply/discharge pipe 6. Further, the second pump 13 and the second on-off valve 12 receive signals from the arithmetic and control unit 8 .

In the above configuration, a signal is sent from the arithmetic and control device 8 to the first pump 1 at a predetermined period, for example, T.
1 and the first on-off valve 10 are put into the supply operation state, and the second pump 13 and the second on-off valve 12 are put into the discharge operation state.
FIGS. 9a, b, c and d are chronological views of FIGS. 2 and 3, respectively. In other words, the internal pressure of the bag-like cell 1 changes sequentially from large, medium, small, medium, and large according to the figures, and the internal pressure of the bag-like cell 2 similarly changes from small, medium, large, medium, and small. Change. Therefore, as shown in the figure, the compression site of the recumbent person changes from the right side to the left side due to the truncated conical shape of the bag-like cells, and further changes from the left side to the right side at a period T.

On the other hand, as shown in FIGS. 4 and 5, when the radius of the bag-like cells 1 and 2 is small, the overlap distance l is r
The vicinity of the larger micropores 15 is sealed by the straight long sides of the sheet 14, and no fluid is ejected from the micropores 15. Furthermore, the first supply means 11 supplies the first
As fluid is supplied through the on-off valve 10, the bag-shaped cell 1 expands due to the internal pressure. As the expansion progresses, the overlapping margin l of the overlapping portion of the sheets 14 gradually decreases. , and finally the sixth
As shown in the figure and FIG. 7, the overlapping margin l of the sheets 14 is almost completely eliminated. When the overlap distance l becomes smaller than r, the fluid inside the bag-like cell 1 passes through the micropores 15 and gushes out to the outside of the bag-like cell 1, and the drying effect is effective in preventing stuffiness caused by sweat, body temperature, etc. of the person lying down. do. Incidentally, although the middle part has been omitted, the ejection from the bag-like cell 1 to the outside occurs through the first minute hole 15 in FIG.
It starts sequentially from the open state.

Further, after the maximum expansion, the internal pressure of the bag-shaped cell 1 is reduced by the control of the first on-off valve 10 as the fluid is ejected, and the bag-shaped cell 1 is contracted, so that the state returns to the state shown in FIG. 4. The period of ejection corresponds to the period T in which the first supply means and the second supply means are switched in response to a signal from the arithmetic and control unit 8.

For example, the arithmetic and control unit 8 may have a function of alternately supplying and discharging fluid to the first bag-like cell 1 and the second bag-like cell 2 at a predetermined period T, and the
When a "fluctuation" characteristic is provided, a rolling motion with "1/fluctuation" is given to the lying person. Therefore, the person lying down is given a "feeling of peace" and can have a comfortable sleep.

Although not shown in the embodiment shown in FIG.
By providing a fluid opening/closing valve in each of the connection parts and opening and closing the valves sequentially from the rear in a predetermined pattern, it is possible to control the movement pattern of the compression part in the lengthwise direction of the recumbent person, for example from the feet to the head.

It is also possible to add stimulation to the person lying down by mixing particulate matter into the fluid.
