The air pillows described in Patent Documents 1 to 3 are simple and can be introduced at low cost, but because they are used while sitting deep in a chair, the disadvantage that the posture of the user is limited is unavoidable, such as artificial dialysis As described above, when the dialysis needle is stuck for a long time as in the same posture as described above, it is not possible to effectively prevent back pain or pain.
According to Patent Document 4, it is considered to correspond to a reclining chair, but because the air chamber is large, it is troublesome to inflate, and not only takes a long time to inflate, but also to mechanically inflate. Requires an inflator.
The technical problem of the present invention pays attention to such a problem, and in particular, realizes an air mat that is easy to put in a large amount of air, and even with the same posture for a long time, it causes back pain, It is possible to effectively prevent suffering.

Claim 1 is an air mat that has a flat surface that comes into contact with the human body and that is used with elasticity by inserting air, and is shaped from the inside of the air chamber in order to expand the volume of the air chamber by inserting at least one hand. Then, the air mat is inflated into the air mat, wherein the air pressure is set to a negative pressure, the outside air is sucked and the air is introduced.

The air inlet / outlet port of an air mat that has a flat surface that comes into contact with the human body and that is used by supplying air with elasticity is at least one hand inserted to expand the volume of the air chamber. An air mat characterized in that it can be shaped from the inside.

According to the third aspect of the present invention, at least part of the air passage in which the surfaces of the pair of flexible magnet plates are in close contact with each other and closed when in use is accommodated in the air mat. The air mat according to claim 2, wherein an inner end of the air mat is an air inlet / outlet.

4. The air according to claim 3, wherein the pair of flexible magnet plates has a protrusion on one side, and the other has a concave shape on which the protrusion enters. Matt.

Claim 5 is an invention of a method of using an air mat. As in claim 1, the air mat itself has a flat surface that comes into contact with the human body, and is used by giving air and providing elasticity. At least one hand is inserted into the air chamber, the air chamber is shaped from the inside of the air chamber to expand the volume of the air chamber, and the air chamber is negatively pressured. Yes. In using the air mat, the air mat is placed on a chair, the flat surface is inclined, and the human body leans against the flat surface.

An air mat having a flat surface with which a human body comes into contact as in claim 1 and using air to give elasticity and inserting at least one hand to expand the volume of the air chamber. According to the method in which the air pressure is negative and the outside air is sucked in and the air is put in, the air chamber becomes negative pressure and the air mat is inflated by sucking in positive outside air, so that one hand can be inserted. A large amount of air can be inflated from the opening of a large air mat, and even a large air mat can be inflated in a short time.

As described in claim 2, the air inlet / outlet port of the air mat that has a flat surface with which the human body comes into contact and that is used with elasticity by inserting air is intended to expand the volume of the air chamber by inserting at least one hand. The size can be adjusted from the inside of the air chamber, and since the outside air is sucked in with the negative pressure of the air chamber, a large amount of air can be easily inflated, and even a large air mat can be inflated in a short time.

According to a third aspect of the present invention, there is provided an air passage that opens in an annular shape when air is taken in and out and allows air to pass therethrough, and in which the surfaces of the pair of flexible magnet plates are in close contact with each other and is closed. The part is housed in an air mat, and its inner end is an air inlet / outlet, so if you close only the air inlet / outlet, use the fact that the internal pressure of the air chamber becomes higher than the external air pressure due to the human load. Thus, the air passage is flexible and deformed to be in close contact and securely closed.

As in claim 4, the protrusion has a ridge on one side of the pair of flexible magnet plates, and the other has a concave shape into which the ridge enters. By fitting, the air is closed so that it cannot pass through, and the closed state is maintained by the internal pressure and restoring force received by the flexible magnet plate, so that the air cannot enter and exit.

As in claim 5, air is used to expand the volume of the air chamber by inserting at least one hand into the air chamber of an air mat that has a flat surface with which a human body comes into contact and that is used by putting air into elasticity. A method in which an air mat having a structure in which outside air is sucked in and put in air is placed on a chair by shaping from the inside of the room so as to create a negative pressure, and the human body leans on the flat surface to be used. According to this, the load caused by the human body acting on the air chamber of the air mat is reduced. For this reason, the portion pierced with the dialysis needle is not moved, and the others are easy to move by leaning diagonally on an air mat with low air pressure, so there is little fatigue and back pain does not occur.

It is a figure which shows embodiment and the use condition of the air mat by this invention. It is a perspective view in the state where the air mat by the present invention was put on the chair. It is a perspective view which shows how to put in and take out the air of the air mat by this invention. It is the conceptual diagram of the air mat by this invention, and sectional drawing of an air passage. It is a figure explaining the effect | action of the air path (closed state) by this invention. It is sectional drawing and perspective view which show embodiment (release state) of the air passage by this invention. It is a perspective view which shows the accommodation process of an air mat. This is an example in which the operating condition of the load on the air mat is bad.

  Next, an embodiment of how the air mat according to the present invention is actually embodied will be described. FIG. 1 is a perspective view showing an example of an air mat according to the present invention and a side view when in use. The upper surface 2 is substantially flat so that the human body 1 leans on, and the lower surfaces 3 and 4 are the chairs. For example, it is formed in a substantially triangular shape so as to correspond to the upper surfaces of the seat 5 and the backrest 6.

A state in which the air mat m of the present invention is mounted on an actual reclining chair is shown in a perspective view as shown in FIG. 2, and the substantially triangular portion 3 of the air mat m is formed on the upper surface of the seat and back of the chair. 4 is placed. In addition, the width is such that the armrests 9 and 10 on the left and right sides are included. 11 is a non-slip, for example, a knitted mesh tape is bonded with a double-sided tape or the like, or a bowl-shaped unevenness is formed like a floating mat.
When this air mat is placed on a chair, a substantially horizontal region 7 at the lower end of the inclined flat upper surface 2 is formed so that the bottom of the human body 1 is easy to sit on the front end of the seat 5 of the chair. ing. As a result, in the use state as shown in FIG. 1 (2), the human body 1 can stably rest on the front end of the seat portion 5 of the chair, and the air mat m is pressurized with the weight of the human body 1. At this time, the air chamber A in the air mat m becomes higher than the atmospheric pressure due to the load of the human body, but leans diagonally, so the load that the air mat m receives from the human body 1 becomes light and punctures the dialysis needle. It can be easily moved outside the area, reducing back pain and pain.

That is, a reclining chair used in conventional artificial dialysis or the like is usually adjusted by placing the waist deeply and tilting the backrest forward and backward. However, because the weight of the upper body concentrates on the waist and thighs that are in contact with the seating surface, it becomes difficult to sit down for a long time.
Therefore, the air mat of the present invention sits seated shallow enough to put a part of the buttocks on the front end of the seat surface, and supports the upper body diagonally with the air mat, thereby dispersing the weight of the upper body without accumulating in the waist.

Since it is an air mat, it is necessary to put air in and out, but since the air mat of the present invention has a large capacity, the air chamber A can be shaped from the inside by inserting at least one hand at the air inlet / outlet. A size is necessary.
FIG. 3 (1) is a perspective view of the air mat m in which one hand is inserted to shape the air chamber A from the inside, and the opening 12 for taking in and out the air is inserted into the air chamber by inserting at least one hand. A is large enough to expand from the inside. That is, when at least one hand is inserted and the air chamber A of the air mat m is expanded and shaped from the inside, the air chamber A becomes negative pressure. Enter. As a result, the air mat m swells to some extent.
When it is desired to vent the air, the air inside the interior A may be pushed out with the opening 12 opened as shown in FIG. For example, when the air mat m is wound from the opposite side and folded, the air in the interior A is easily pushed out from the opening 12, which is convenient for carrying and storage.

FIG. 4 is a principle view showing an improved type of the air mat m of FIG. 3. When air is taken in and out, (2) it opens in an annular shape as shown in FIG. An air passage 15 is formed in which the surfaces of the magnet plates 13 and 14 are in close contact with each other and are closed. At least a part of the air passage 15 is in the air mat m, and the inner end thereof is an air inlet / outlet port 121.
FIG. 5 shows the air mat m corresponding to FIG. That is, after inhaling outside air about 60 to 80%, the entrance / exit 121 is closed, and if it sits shallowly on a chair as shown in FIG. 5 (1) and leans on it, the inside of the air mat m becomes higher than the atmospheric pressure due to the weight of the human body, The high pressure is applied to the outer surfaces of the pair of flexible magnet plates 13 and 14 as shown by arrows, so that the inner surfaces of the flexible magnet plates 13 and 14 are in close contact with each other and are securely closed, and air leaks. Does not occur. As described above, since a part of the buttocks is placed on the end of the opening / closing opening, the air in the air mat can be prevented from coming out. Note that one flexible wall 14 can be integrated with the air mat m to receive atmospheric pressure.
The amount of air in the air mat is 60-80%, so it is better to be conservative so that the upper body can be tilted according to the patient's body shape.
This pressure state is shown in a sectional view as shown in FIG. In addition, 18 is a cushion and is not indispensable.

Depending on the position of the load W acting on the air mat, the connecting portion side of the air passage 15 with the air mat m may be pulled up and down as shown in FIGS. Since this connection part and the entrance / exit 121 of an inner end are separated, the air in the air mat m does not leak.
In order to prevent the opening, the air passage 15 can be extended long as shown in (2), or the machine can be used with a chuck or Velcro (registered trademark) that is often used in bags as shown in (3). It is good to close it.

FIG. 6 is a cross-sectional view and a perspective view showing an embodiment of the air passage 15 and the entrance / exit 121, and the air mat m shows only a joint portion with the air passage 15. An annular passage 15 is formed by flexible magnet plates 13 and 14 made of synthetic resin so that air can pass therethrough.
Now, in order to expand the volume of the air chamber A of the air mat m, a hand is inserted into the air chamber A and shaped into a negative pressure, and the outside air is naturally sucked and air is introduced. When the hand is removed after about 50 to 80% of air has entered, the air passage is restored by the elasticity of the flexible magnet plates 13 and 14, and the doorway 121 is naturally closed.
When the human body leans against the air mat m, the inside of the air mat m becomes higher than the atmospheric pressure due to the load of the human body, and the high pressure is applied to the outer surfaces of the pair of flexible magnet plates 13 and 14 as indicated by arrows. Therefore, the inner surfaces of the flexible magnet plates 13 and 14 are in close contact with each other and are reliably closed.

Furthermore, at the entrance 121 of the inner end of the air passage 15, the ridge 16 is provided on one side, and the ridge 16 into which the ridge enters is provided on the other side. The air is closed so that it cannot pass through. The ridges 16 and the recesses 17 can be opened and closed more reliably by making the surface sticky, such as silicone resin, or using a synthetic resin rich in elasticity and restoring force.
Not only the entrance / exit 121 but also the ridges 16 and the ridges 17 may be formed on the inner surfaces of the flexible magnet plates 13 and 14 forming the air passage 15. Further, when a magnetic thin plate in which a permanent magnet powder mg is kneaded into a synthetic resin is used as the flexible magnet plates 13 and 14, the entrance / exit 121 and the air passage 15 are automatically formed by the action of an adsorption force when one hand is pulled out. Closed.

If an elastic body is built in the air mat m in advance, it is sufficient to insert the substitute 19 as shown in FIG. That is, if the substitute 19 is inserted and the entrance / exit 121 is forcibly opened, the elastic body is opened and the outside air can be automatically sucked at a negative pressure. After inhalation, the substitute 19 is automatically closed by the magnetic force of the permanent magnet powder mg when the substitute 19 is removed from the entrance / exit 121. And (1) When it folds from the part far from the entrance / exit as shown in the figure, the inside of the air mat m is exhausted and the elastic body is also folded. Thereafter, it is folded in the order of (2) → (3), and when the substitute 19 is a bag, the folded air mat m can be stored and carried or moved.

As described above, since the air chamber of the air mat is expanded with one hand to generate a negative pressure and the outside air is sucked, even a large amount of air can be easily introduced. In addition, the lower surface can handle complex shapes such as the seat of the chair and the upper surface of the backrest, making it easy to use.
