[Technical field to which the device belongs]

  This invention is for people who are forced to spend time in supine or sitting position, for example, For example, if you are a bedridden patient, a wheelchair, or other Cushion with excellent shock absorption and body pressure dispersion function suitable for chair occupants Bed material, especially the bed mat to prevent pressure sores and pressure disorders. Cushions used as pad, bed pad, cushion itself or their filling Regarding the chord material.

[0002]

[Prior art]

  One of the problems that accompanies long-term bedridden bed life and wheelchair life is (Bed sores) and pressure disorders occur, which is a pain for the person. Needless to say, it can cause back pain and trouble for caregivers such as changing positions. It is labor-intensive, and its prevention or mitigation is desirable for both parties and strongly requested. It is about to be done.

[0003]   Decubitus is a part of the body that is lying down when sleeping or sitting in the same posture for a long time This can be done because blood does not pass through for a minute, nutrition is insufficient, and the skin is torn.   Decubitus, especially on the back of the head, shoulder blades, elbows, coccyx, hips, heels, etc. It is easy to make it on the part where the bone is protruding or the weight is applied.

[0004]   This is because excessive pressure is applied to the futon, etc. at those parts, and This is because uneven distribution or body pressure distribution occurs. Therefore, there are no such bedsores In order to prevent compression disorders, or to prevent their progress, body pressure distribution has been conventionally used. To prevent this, various bedsore prevention tools have been developed, such as bed mats and bedsores. Bed pads, cushions for local use on areas that tend to occur, Alternatively, a cushion material or the like as a cushion pad is commercially available.

[0005]   And these cushions, cushions such as bed mats or bed pads Materials include, for example, air cushion, polyurethane foam, and super flexible synthetic rubber. , Various fluid gels, latex, etc. are used.

[0006]

[Problems to be solved by the device]

  However, in the case of the air cushion, it means that you can save the trouble of nursing care. Although good for the caregiver, it is not necessary for the sick because of motor noise and instability. However, it cannot be said that it is comfortable, and there is a pity that it cannot satisfy both parties.   In addition, an air valve is installed to keep the pressure at an appropriate level inside the air cushion. There is one that automatically adjusts the air pressure of, but there is a problem in terms of cost.

[0007]   On the other hand, when using polyurethane foam, both hard and soft foam and low impact resilience That seeks to disperse body pressure by elasticity by combining with elastic foam , A specially shaped structure to disperse body pressure, and a urethane foam jacket It is well known that thorium acrylic resin and other fluid gels are used. They generally have problems with viscoelasticity and tend to sink easily.   In addition, in the case of super flexible synthetic rubber, special polymer is used. The disadvantage is that it is expensive among the cushion materials.   In addition, since various gels do not have shape retention properties, they can disperse body pressure during long-term use. There is a drawback that

[0008]   Therefore, in view of the above-mentioned circumstances, the present applicant has improved the soft synthesis by In the resin inner bag, as a core material or skeleton material of a size that fits the size of the inner bag, The upper honeycomb stitch layer, the lower honeycomb stitch layer, and both honeycomb stitch layers are connected Knitted with a connecting thread layer to form a gap in both the horizontal and vertical directions. And inserting a synthetic fiber knit having a three-layer structure And the inner space of the inner bag through the gaps in the horizontal and vertical directions. A bag body filled with a molecular elastic gel filler and sealed was covered with an outer bag cover. I proposed a cushion material. (Japanese Patent Application No. 2001-109480) However, the cushion material according to the above-mentioned proposal has a weight difficulty and is used continuously. There is a problem in shape retention due to deformation caused by use, and a problem that it is not practical in appearance I found out that there is.

[0009]   In consideration of the above-mentioned situation, the present invention copes with this situation and is particularly excellent in the body pressure dispersion function. At the same time, it is a cushion that has excellent shock absorption and suits practicality in terms of weight and appearance. We provide shock absorbers to reduce the impact of cold air and keep them warm in winter. To maintain fatigue and reduce fatigue for people who have a long supine or wheelchair life. The purpose is to measure.

[0010]

[Means for Solving the Problems]

  That is, the feature of the present invention which meets the above-mentioned purpose is that the inner bag is provided in the soft synthetic resin inner bag. As a core material or skeletal material of a size that matches the size of Knitting from a lower honeycomb stitch layer and a connecting yarn layer connecting both honeycomb stitch layers And has a three-layer structure in which gaps are defined in both vertical and horizontal directions. As the sewage is inserted, the knitting gaps of the knitting are filled in the entire inner space of the inner bag. And the polymer elastic gel filler is filled and sealed through the gaps in both the vertical and horizontal directions. Inside the flexible frame case made of foamed resin material. It is housed in, covered with an aluminum vapor deposition sheet and covered with an outer bag cover.

[0011]   Here, the knitting having a three-layer structure is made of honeycomb-shaped units. Used as a jelly-like polymer elastic gel, carboxymethylcellulose sodium It is preferable to use a diaphragm.   In addition to the rhombus, the honeycomb shape includes polygonal shapes such as hexagons and octagons. It   Moreover, as a yarn constituting the synthetic fiber knitted fabric, a yarn of 400 d to 1000 d It is preferable to use multifilament yarn.

[0012]   A foamed polyolefin sheet is usually used as the inner cover that covers the bag. Foamed polyethylene material is suitable for flexible frame As a vapor deposition sheet, aluminum vapor deposition was applied to foamed polyethylene by known means. Sheets are commonly used.   It is environmentally friendly to use expanded polyolefin and expanded polyethylene as described above. It is very suitable.

[0013]

[Action]

  The cushioning material according to the present invention is provided with a double-sided inner and outer double-walled bag having a lot of gaps and gaps. Three-dimensional skeleton called cam three-layer structure knitting, its gaps, gaps and inner space of inner bag A jelly-like polymer elastic gel that fills the entire surface (this is also a micro gel) Has a network structure in which the liquid is contained in the interstices of the molecular colloid skeleton). Since it is stored, the former has excellent shape retention, elasticity and rigidity, and the latter has viscoelasticity and fluidity. Both features are combined.

[0014]   That is, the liquidity of the latter becomes the liquidity suppressed by the former three-dimensional skeleton. An excellent body that exhibits balanced shape retention, fluidity, viscoelasticity, and rigidity as a whole Pressure dispersibility is achieved.   Moreover, the cushion material is housed in a flexible frame case, Since it is closed with a lid and covered with an outer bag cover, it excels in shock absorption and Since it is covered with an aluminum vapor deposition sheet, it blocks cold air and keeps the heat inside. .

[0015]

[Embodiment of device]

  Hereinafter, specific embodiments of the present invention will be specifically described with reference to the accompanying drawings. .

[0016]   1 is a schematic view of an example of a cushion material according to the present invention, and FIG. 2 is a cushion portion of FIG. 3 is an enlarged cross-sectional view of the bag body 5 in the material, and FIG. 3 shows the structure of the knitted fabric contained in the bag body 5. It is a figure.   In these figures, the cushion material is used as a core material or skeleton material in the inner bag 8. Honeycomb tri-layer knit 6 and filled to fill all inner space of inner bag A jelly-like polymer elastic gel filler 7 is filled to form a bag body 5. As shown in FIG. 1, the bag body 5 is made of expanded polyolefin for fail-safe inner bag 8. The inner cover 2 made of a sheet covers and protects.

[0017]   As shown in FIG. 3, the knitting 6 as the core material or the skeletal material has an upper honeycomb stitch layer. 11 and the lower honeycomb knitting layer 12 and the connecting yarn layer 13 connecting the two It is organized in layers.   In this case, each polygonal honeycomb unit 1 of the upper and lower honeycomb stitch layers 11, 12 1a and 12a may be rhombus (igeta shape) as shown in the figure, or may be hexagonal or octagonal. In addition, the upper and lower honeycomb knitting is performed by the connecting yarn 13a at those stitch knots. The grain layers 11 and 12 are connected.   Thus, the three-layered honeycomb structure has an intermediate structure inside each honeycomb unit and between the connecting yarns. It defines an empty space or gap 14 and gives a large spatial structure.

[0018]   The three-layer knitted fabric is usually made of synthetic fiber yarn, for example 400d to 1000d knit. Dub using mono or multi-filament yarns such as Ron or polyester fiber It can be knitted by a Roussel knitting machine or the like.   That is, in the double Russell knitting machine, the front needle row and the rear needle row are Each of them is subjected to chain stitching, and the upper and lower honeycomb stitch layers 11 and 12 are formed by the front and rear chain stitch rows. While forming the chain, the chain stitches at zigzag positions are appropriately connected between the front and rear chain stitch rows. The connecting yarn 13 is formed by connecting the knot with the yarn 13a, and A warp knitted fabric including the honeycomb stitch layers 11 and 12 and the connecting yarn layer 13 is knitted.   In knitting the above warp knitted fabric, the connecting yarn is more advantageous than the upper and lower knitting layer knitting yarns. Using thick denier yarns, for example, 400-600d upper and lower stitch layer knitting yarns, Setting the connecting yarn to 800 to 1200d is effective from the viewpoint of shape retention.

[0019]   On the other hand, the jelly-like polymer elastic gel 7 as a filler is a colloid of polymer substance aqueous solution. An elastic gel obtained by gelating (sol), which has high viscosity and high elasticity, It has moderate liquidity, not fluidity.

[0020]   Examples of such a polymer substance include carboxymethyl cellulose sodium. (CMCNa), sodium alginate, polythiourea acetate, starch, water Soluble urea resin, sodium polyacrylate, partial hydrolysis product of polyacrylamide Salt, polyethyleneimine, polyacrylamide, polyoxyethylene, etc. are used It is possible, but CMCNa is not affected by the elastic temperature, and the temperature is low. It does not become hard and does not become too soft even at high temperatures, and it maintains a certain viscoelasticity for easy handling. Moreover, it is advantageous in terms of cost and cost.

[0021]   The honeycomb three-layer structure knitted fabric 6 and the jelly-like polymer elastic gel 7 are The hollow spaces and gaps that exist in the human The contents of the sealed inner bag 8 are stored in the inner bag 8 as a package and sealed. Is covered with an inner cover 3 for protection, to form a cushioning material unit. The foam material is a foamed resin material, especially a foamed polyolefin such as foamed polyethylene. It is housed in a flexible frame case 2 of the required thickness made of material, and the upper surface is covered with an aluminum vapor To prevent cold air by blocking the lid with a toe 4, use them as a foamed polyolefin sheet, etc. The cushion material of the present invention is constructed by covering with an outer bag cover 1 made of There is.

[0022]   Here, the flexible frame-shaped case 2 is relatively flexible and has excellent impact absorption properties. Len material is used to form a frame-like structure with no lid. When stored, the cushioning material reduces the overall weight due to the shock absorbing performance of the case 2. It is possible to reduce.   In addition, the inner cover 3 covering the cushion material protects the cushion material itself, and It holds the position stably in a flexible frame-shaped case. The stop has an adiabatic effect to prevent cold air from entering the inside, for example, in winter.

[0023]   Thus, the three-layer structure knitted fabric 6 is used as the core material or the skeleton material, and the polymer elastic gel material 7 is used. A flexible frame-shaped case 2 having a shock-absorbing capacity and a bag body 5 filled with aluminum and an aluminum vapor deposition sheet The present invention, which is held by a lid composed of 4 and is integrally covered by the outer bag cover 1. The cushion material is constructed.

[0024]   The cushioning material obtained as described above is itself a cushion for preventing bedsores. Used by people living on a chair, such as outside the bed mat, wheelchairs, and other professional drivers. It is suitable and effective.   In that case, the inner bag 8 serves to prevent leakage of contents and as a container. Therefore, the outer bag cover 1 itself has a role of a face on the outside of the product, or is only for protection. It can be said to fulfill its function. Therefore, the outer bag cover 1 should be appropriately decorated with colors and patterns. Alternatively, a fiber material, leather or the like may be used in combination.   In addition, the inner bag 8, the outer bag cover 1, the inner cover 3, the flexible frame case 2, Lumi vapor-deposited sheet 4 and the like are dust, polyethylene, polyp from the viewpoint of environmental problems. Polyolefin such as ropylene is preferred, but other strength It is also possible to appropriately use any material.

[0025]

[Effect of device]

  The cushion material of the present invention is a three-dimensional honeycomb structure knitted fabric with many gaps or hollow spaces. From the skeletal material and the jelly-like polymer elastic gel filler filled through the gap Because they are configured to complement each other, the free flow of jelly-like polymer elastic gel Is moderately constrained by the skeletal material to achieve a good balance of shape retention, viscoelasticity and rigidity It   Therefore, when used as a bed mat, pad, or cushion, the body pressure is dispersed. Is very good and prevents bed sores due to beds and pressure disorders such as wheelchairs. Can be reduced or reduced.   Moreover, the cushion material itself is stored in a flexible frame case and Since it is held by the lid of the wearing sheet, it has excellent shock absorption and cool air. To prevent cold air from invading in the winter, and a more flexible frame-shaped case. The cushioning material complements the performance of the cushioning material alone and reduces the weight of the cushioning material alone. It is possible to improve the practical effect by reducing the overall weight and make the user comfortable for a long time. It has a remarkable effect of being able to maintain a supine or sitting position.   If CMC sodium is used in the filling material, the same gel will be used regardless of the season. It has the advantage that it is easy to use because its hardness is maintained.
