Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to an air mat for wave pine surge that is ideal for preventing bedsores for sick people, bedridden elderly people, etc.

(Prior Art) As an example of a conventional air mat for wave pine surge, there is one with a structure as shown in Figs. 6 and 7. The air bladders 21 in the second row are arranged in a zigzag pattern, and the upper surface of the air bladder 21 in the second row is provided with a suitable number and arrangement of minute air ejection holes. 21, 1st
It is always located between the air sac 22 of the number row and the air sac 23 of the 3rd row, and air is always blown out from the air sac during use. U2
2 and 23, pressurized air is supplied alternately to bring about the wave pine surge effect through the expansion and contraction actions alternately and repeatedly performed by the same air bladders 22 and 23. This is intended to keep the user's skin dry at all times by the air blown out from the air sacs 21 in the second row, thereby preventing stuffiness.

(Problems with the Prior Art) However, in the above air mat, the air sac dedicated to air discharge is sandwiched between air sacs that repeatedly expand and contract as pressurized air is supplied and exhausted. As a result, the area of the main pine surge surface that repeatedly expands and contracts becomes smaller, creating areas where the pine surge effect does not extend.

Furthermore, since air is constantly being blown out, it is not possible to adjust the drying process to the preferences and physical condition of the user, such as a sick person.

This invention was devised to solve the above-mentioned problems, and it maximizes the expansion and contraction area of the pine that performs wave pine surge, and
To provide a wave pine surge capable of optimally controlling the amount of air ejected for drying the skin and an air pine suitable for preventing bedsores.

(Means for Solving the Problems) The present invention, as a means for solving the above-mentioned problems, consists of at least four independent air sacs arranged regularly and connected in a zigzag pattern. This is an air mat for wave pine surge, in which pressurized air is supplied and exhausted to the air sacs in the first and fourth rows to alternately expand and contract them, and the air mats in the adjacent second and third rows are A suitable number and arrangement of minute air ejection holes are drilled on the upper surface of the air sac, and pressurized air is selectively supplied to and exhausted from the two air sacs having these air ejection holes, alternately. It has a structure that repeatedly expands and contracts, and alternately blows out air from each pouch equipped with air blowing holes.

(Function) Of the four air sacs regularly arranged in a zigzag pattern, the air sacs in the first and fourth rows that do not have air injection holes, When pressurized air is alternately supplied to the two air sacs equipped with air sacs and then exhausted, air sacs that do not have air ejection holes repeatedly expand and contract, producing the normal wave pine surge effect. Since pressurized air can be supplied individually and alternately to the air sacs that have ejection holes, the air sacs also work together with the air sacs in the first and fourth rows. At the same time as the pine surge effect, pressurized air is ejected from the air outlet when the air sac expands to dry the skin. The amount of air ejected can be adjusted independently from the air sac, which does not have air ejection holes. It is also possible to maintain all the air sacs in an inflated state at all times, and simultaneously blow out air from the air sacs in the second and third rows (see Fig. 5).

(Example) Hereinafter, an example of the present invention will be described in detail with reference to the drawings.

FIG. 1 is a schematic perspective view, and FIG. 2 is a detailed partial plan view of the air mat.

In this example, four independent air cells 1, 2,
3 and 4 are regularly arranged and connected in a zigzag pattern, and air blow-off holes 7 are provided on the upper surface of two adjacent air bladders 2 and 3, excluding the first and fourth rows.
It is equipped with the following. In this embodiment, narrow band-shaped air bladders 2 and 3 equipped with air ejection holes 7 are arranged side by side over the entire width of the air mat main body 5.
The air mat body 5 is folded back in a zigzag pattern from the left to the right and from the right to the left, and is densely arranged over the entire length of the air mat main body 5 in the longitudinal direction, with the two air bladders 2 and 3 as the boundary. The air sacs 1 and 4, which are independent of each other, are connected to the horizontally separated parts (upper and lower in Fig. 2), and the air sacs 1 and 4 are adjacent to the air sacs 2 and 3. All of these air sacs 1 to 4 form an air mat main body 5. In addition, in FIG. 2, 2' and 3' are portions that communicate with the unillustrated portions of the right ends of the air sacs 2 and 3, and surround the outside of the air sacs 1 and 4. The air sacs 2' and 3' are in communication with the air sacs 2' and 3', and the air ejection holes 7 are not provided in the air sacs 2' and 3'. Further, a hose 6 for supplying and discharging pressurized air is connected to each of the air sacs 1 to 4,
Connecting portions 16, 26, 36, and 46 for connecting and separating the hose 6 are provided on the sides of the air mat 5.

The air ejection holes 7 formed in the upper surfaces of the air sacs 2 and 3 are minute and many are formed at almost the same position, but the ones formed in the air sac 2 and the air sac 3 are different. The formations are either aligned with each other (Figure 1) or arranged in a pique pattern (Figure 2).
figure). Note that FIG. 3 shows an example in which the air jet holes 7 are arranged in an irregular pique shape.

Further, the other two air sacs 1 and 4 are not provided with air ejection holes 7.

Although not shown, the hose 6 is connected to a pressurized air supply/exhaust source, and is further connected to the air bladders 1, 2, 3 and 4, but the 4th
The examples shown in Figures a and 4b are air sacs 1, 2 and 3,
This is an example in which air supply and exhaust are performed alternately for the air conditioners 4 and 4.

Next, the operation of the above embodiment will be explained.

When pressurized air is individually supplied to and exhausted from the air sacs 1, 2, 3, and 4, the two air sacs 2 and 3 provided with air ejection holes are repeatedly expanded and contracted. In the expanded state, pressurized air is discharged from the air outlet. On the other hand, when pressurized air is alternately supplied and exhausted to air sacs 1 and 4, which do not have air ejection holes, the air sacs expand and contract. On the other hand, air sac 2 expands and contracts at the same time as air sac 1, and air sac 3 expands and contracts simultaneously with air sac 4, so the total air in air sacs 1 and 2 and air sacs 3 and 4 is At the same time as the alternating expansion and contraction of the sacs produces a wave pine surge effect, air is ejected alternately from the sacs 2 and 3. In this way, some air sacs blow out air to prevent the user's skin from getting stuffy, while air sacs 1 and 4 perform wave massage over a wide area.

In addition, as shown in Figure 5, all air sacs 1 to 4
can also be expanded all at once.

Further, the amount of air ejected is controlled to be an amount and strength that suits the physical condition of the user by adjusting a flow rate regulating valve and a pressure control valve (not shown).

Although not particularly shown, the combination of operations of the air sacs 1 and 4 dedicated to expansion and contraction and the air sacs 2 and 3 that have both functions of expansion and contraction and air jetting is achieved by the hose 6 and the connection part 16 connected to them. , 26, 36, and 46 can be changed freely.

In the above embodiment, the case where two air sacs each having air ejection holes 7 are provided is shown, but when there are three or more air sacs, there are two cases: an odd number of air sacs and an even number of air sacs. , the order of supply and exhaust of pressurized air to and from the air sac will naturally change. However, by changing the air distribution order and hose connection order arbitrarily or based on a preset program, it is possible to effectively provide the user with the optimal wave pine surge and air jet action in any case. can bring.

(Effects of the invention) The air mat for wave pine surge of the present invention has at least four independent air sacs, each of which expands and contracts by supplying and exhausting pressurized air, which are regularly arranged and connected in a zigzag shape. This is an air mat for wave pine surge, in which pressurized air is supplied and exhausted to the air sacs in the first and fourth rows to alternately expand and contract them, and the air sacs in the adjacent second and third rows are A suitable number and arrangement of minute air ejection holes are drilled on the upper surface of the sac, and pressurized air is selectively supplied to and exhausted from the two air sacs having these air ejection holes to inflate them alternately. Since the air sacs are repeatedly contracted and air is ejected alternately from each air pouch provided with an air ejection hole, when the first and fourth rows produce a wave pine surge effect, air is ejected from other air sacs. Since the wave pine surge effect can also be brought about by the air sacs, the pine surge effect can be obtained over the entire surface of the air mat body, and in combination with the air jet action, effective pine surge can be performed. Also, as mentioned above, there are at least two air sacs from which air blows out.
It is very convenient to control the air jet and the amount of air jet, and it is possible to obtain a wide variety of pine surge effects and drying effects.

Therefore, the present invention can be used not only as a pine surge mat but also as a bed sore prevention mat, and can be used in the optimal condition depending on the physical condition and other conditions of the sick person or other user. effective.
