Description

Description: TECHNICAL FIELD The present invention relates to an air mat for preventing floor rubs, and more particularly to an air mat for floor rubs that is inexpensive and can be easily used in general households.

(Prior Art) When lying on a bed for a long period of time, it is often found that the part corresponding to the bedding is unconsciously pressed to cause blood circulation disorder, and a pressure ulcer, so-called bed-rubbing symptom appears, which is fatal to the sick person. The current situation is that hospitals and homes are having difficulty dealing with such treatment.

In order to prevent or treat this bedsores, it is important to avoid long-term local pressure and to change the sleeping position, use a flexible cushion bed, and use it by a nurse's hand or special A method of using a rolling bed to change the position of the sick person is used. However, although this method is effective in preventing floor rubs, it is not very effective when floor rubs have already occurred, and rather has the opposite effect when using soft cushioning bedding. In consideration of these circumstances, the present inventor previously found that the Japanese Utility Model Publication No. 52-43195 or the Japanese Patent Publication No.
As disclosed in the publication, a mat suitable for preventing floor abrasion due to air outflow and for treating floor abrasion is provided.

(Problems to be solved by the invention) However, in the mat described in Japanese Utility Model Publication No. 52-43195, a small amount of air continuously leaks from the inside of the air mat, which is effective in preventing or treating floor rubs. However, on the other hand, it has a weak supportive force for the body and has a drawback that the inside of the mat must be maintained at an excessively high air pressure. The mat described in Japanese Patent Publication No. 61-4524 has the advantage that an excessive air pressure is not required and a small amount of air can be effectively used, but it is generally used because the mat production cost increases. At present, there is a demand for a mat which is not necessarily suitable for household use and which is easy to use and is convenient for preventing floor rubs and treating.

(Means for Solving Problems) The present invention has been made for the purpose of improving various disadvantages of the above-described conventional mats of the above-described type. A fixed number of rows of body-supporting air chambers that constantly seal the air supplied during use to maintain an inflated state at a constant height during use, and further, a mat between adjacent body-supporting air chambers. An auxiliary air chamber whose bulge height is smaller than that of the body-supporting air chamber is provided on the upper surface of the main body, and a large number of pores for air leakage are provided in this air chamber. It is configured to communicate with an air supply fan so that air is leaked from the pores.

The width dimension of each of the air chambers which can be sealed for body support is not particularly limited, but is preferably about 8 to 10 cm, and the thickness (height) of the air chamber is about 8 to 10 cm. It is desirable from the viewpoint of sex. Also, the width of the air chamber provided with pores is preferably about 2 to 5 cm.

The pores are provided on the side surface and / or the top surface of each air chamber, and the size thereof is preferably 0.2 to 0.6 mm in diameter, and the amount of air can be adjusted appropriately.

Further, as a convenient sheet material for forming the mat of the present invention, a synthetic resin sheet may be used, but it is desirable to use a thin monofilament thread of synthetic resin for warp and weft in a high density woven material. A non-breathable sheet obtained by applying a heat-adhesive resin to a sheet, or a sheet obtained by applying a synthetic resin or rubberizing a canvas such as a tent cloth. It is suitable.

(Operation) During use, air is supplied to the body-supporting air chambers to expand these body-supporting air chambers, and the air supply port is closed by a plug to keep the air chambers in an inflated state with a certain height. Then, the sleeping person is elastically supported by these body-supporting air chambers. If air is supplied to the sub air chamber in this state,
Sub air chamber Air leaks as a breeze from the large number of pores formed in these sub air chambers into the space between adjacent body supporting air chambers, acting on the back and waist of the sleeping person and causing bed sores. It has the effect of preventing or treating bedsores.

At this time, since the sub-air chamber has a lower bulging height than the body-supporting air chamber, a gap is created between the sleeping person and the sub-air chamber supported by the body-supporting air chamber, and the weight of the sleeping person may cause a gap. Even if compressed to the body-supporting air chamber to some extent, the adhesion between the sub-air chamber and the sleeping person is small. Therefore, a large pump is used for outflow of air from the pores formed in the sub-air chamber. It is smoothly and surely performed by a small air supply fan having a small air supply capacity.

(Embodiment) Referring to the drawings showing an embodiment of the present invention,
(1) is a mat main body formed of a non-breathable sheet material, and a plurality of rows of body-supporting air chambers (2) are provided on the upper surface side of the mat main body (1) in the longitudinal direction of the mat main body (1).
(2) and the body-supporting air chamber (2)
Between the body support air chambers (2) and (2), sub-air chambers (3) and (3) having a smaller exposed height and width than the body support air chambers (2) are formed, and the body support air chambers (2) ( By closing one end of 2) and connecting the other end to a common air supply passage (4), the air supply opening (5) of the air supply passage (4) can be closed by a plug (6). The body of the sleeping person is supported by the air supply expansion of the body-supporting air chambers (2) and (2). On the other hand, the sub-air chambers (3) and (3) are provided with a large number of pores (7) and (7) at positions facing at least the back and waist of the sleeping person, and one end is closed and the other end is common. To the air supply passage (8) of the air supply passage (8) and the opening (9) of the air supply passage (8) through the tube (10).
1), and by operating the air supply fan (11), clean air is introduced into the sub air chambers (3) (3) through the filter (12), and the sub air chambers (3) (3) ) Is inflated and air is leaked from the pores (7) and (7) so that the air flows toward the body of the sleeping person through the bed.

The air chamber in the above embodiment is the air chamber (2).
The air chambers (2) and the sub air chambers (3) and (3) may be alternately formed with air chambers having the same width of about 15 to 30 mm.

Further, the body-supporting air chambers (2) and (2) can be used by appropriately adjusting to an air pressure suitable for each user to sleep, and further leak from the auxiliary air chambers (3) and (3). The amount of air is
If the skin feels or does not feel, or if the amount of air is not enough, if it becomes too large, it will take away the body heat and promote the debilitation of the patient.

In the figure, the shaded area indicates the heat-bonded area of the mat main body (1) formed by two upper and lower air-impermeable sheets.

When using the floor mat prevention air mat configured as described above, an appropriate air supply means such as an air supply pump is connected to the air supply opening (5) in the body supporting air chamber (2) (2). Air is supplied to the air chambers, the air chambers (2) are expanded to a certain height, the air supply is stopped, and the air supply means is removed from the air supply openings (5) to open the air supply openings (5). It is closed by the plug (6) to keep the body-supporting air chambers (2) (2) in an inflated state.

When the patient sleeps on the mat in this state, the patient is elastically supported on the mat by the inflation pressure of the body-supporting air chambers (2) (2).

In this way, when the sleeping patient is supported by the body-supporting air chambers (2) and (2) that are inflated to a certain height, they are provided between the adjacent body-supporting air chambers (2) and (2). Since the sub air chamber (3) is located below the back and waist of the patient, a gap is created between the patient and the sub air chamber (3) and the sub air chamber (3) is drilled. The large number of the open pores (7) are not blocked by the patient, and are completely opened toward the gap.

After that, when the air supply tube (10) of the air supply fan (11) is connected to the opening (9) of the air supply passage (8) to supply air into the sub air chamber (3), these sub air Room (3)
Air easily leaks from the pores (7) into the above-mentioned gap as a breeze, and acts on the back and waist of the patient to prevent the occurrence of bedsores or to treat the patients with bedsores.

At this time, since the sub-air chamber (3) has a lower bulging height than the body-supporting air chamber (2), even if the sub-air chamber (3) expands when air is supplied, its pores (7) Is not close to the patient, and even if the body-supporting air chamber (2) is compressed by the weight of the patient, the amount of air supplied to the sub-air chamber (3) can be adjusted to reduce its expansion amount. Since the pores (7) can be kept in a state in which they are not closed by the patient, and the air pressure in the sub air chamber (3) is small even if they are in close contact with the patient's back or waist, The air leak pressure causes the sub-air chamber (3) to deform smoothly in the direction of contraction and smoothly flow out.

(Effect of the Invention) As described above, the air mat for preventing bedsores according to the present invention is provided on the upper surface of the mat main body (1) formed of the air-impermeable sheet at regular intervals in the width direction of the mat main body (1). , The mat main body (1) that seals the air supplied when the mat is used and always maintains an expanded state of a certain height
A plurality of rows of body-supporting air chambers (2) extending in the lengthwise direction of the mat main body (1) are formed on the upper surface of the mat main body (1) along the space between the body-supporting air chambers (2) and (2). Pore (7)
And a sub-air chamber (3) having a lower bulge height than the body-supporting air chamber (2) is provided in parallel with the body-supporting air chamber (2). Since the air supply fan (11) is connected to the air supply opening (9), air is supplied into the body-supporting air chamber (2) at the time of use, and these air chambers (2) are When the sleeping person's body is elastically supported while being held in a state of being inflated to a certain height, a sub air chamber (3) provided between the adjacent body supporting air chambers (2) (2).
Is located below the back and waist of the sleeping person, and a gap can be created between the sleeping person and the sub air chamber (3).

Therefore, the large number of pores (7) formed in these sub air chambers (3) should not be blocked by the back or waist of the sleeping person, but should be entirely open toward the above gap. When the air is supplied into the sub air chamber and the air chamber (3), the pores (7) are generated with a slight air pressure feeding force.
The air that can be smoothly and surely leaked as a breeze from the air, and therefore can prevent bed slip by using a small air supply fan (11) without using a large air supply pump as in the past. A mat can be provided.

Further, since the sub-air chamber (3) has a lower bulging height than the body-supporting air chamber (2) as described above, even if the sub-air chamber (3) expands when air is supplied, its pores (7) does not come into close contact with the sleeping person, and even if the body-supporting air chamber (2) is compressed by the weight of the sleeping person, the amount of air supplied to the sub-air chamber (3) is adjusted to adjust the amount of the sub-air. It is possible to lower the expansion height of the chamber (3) so that the pores (7) are not closed by the back or waist of the sleeping person, and the adjacent body-supporting air chambers (2) (2). ) Is effectively flowed to prevent the occurrence of bedsores or have a therapeutic effect on patients with bedsores.
