Description

[Detailed Description of the Invention] [Technical Field of the Invention] The present invention relates to a pine mattress used as a mattress, and relates to a structure for preventing bedsores.

[Technical background of the invention and its problems]

Traditionally, the mattress for sick people was a mattress made of sponge padded with cotton padded on top of a sponge pine mattress. Because the sponge does not have the ability to remove moisture from cotton futons, the cotton futons that absorb moisture tend to become hard, and patients who are unable to move can become congested in the areas that come into contact with the hard cotton futons, and the moisture can easily cause bedsores. There's a problem.

[Purpose of invention]

In view of the above-mentioned problems, the present invention consists of stacking two layers of breathable elastic bodies having a large number of chevron-shaped protrusions with a breathable sheet in the middle to form upper and lower cushion layers. An intermediate retaining layer made of a flexible corrugated bending plate is interposed between the cushion layers, and this intermediate retaining layer is made permeable in a direction perpendicular to the pitch direction of the corrugations. The upper and lower cushion layers form ventilation holes, and the upper and lower cushion layers each have a large number of chevron-shaped protrusions stacked on top and bottom to maintain soft cushioning properties and prevent pressure on the contact surface between the body and the cushion layer. Furthermore, the intermediate retaining layer has air vents in the flexible corrugated bending plate, and air is exhausted from the upper and lower cushion layers and supplied to the cushion layer in a direction perpendicular to the direction of the pitch of the corrugations. Moisture is removed from the cushion layer of the cushion, and bedsores are prevented through flexible contact and moisture removal.

[Summary of the idea]

The present invention consists of upper and lower cushion layers formed by overlapping two layers of breathable elastic bodies having a large number of chevron-shaped protrusions with a breathable sheet in between, and a flexible cushion layer interposed between the upper and lower cushion layers. The intermediate retaining layer is made of a flexible corrugated bending plate, and this intermediate retaining layer can be ventilated in a direction perpendicular to the pitch direction of the corrugations, and has a large number of ventilation holes between the top and bottom of the corrugations. The upper and lower cushion layers made of two layers of air-permeable elastic material maintain soft cushioning properties and absorb moisture, and the intermediate retention layer allows exhaust and air supply to the upper and lower cushion layers.

[Example of idea]

An embodiment of the present invention will be described with reference to FIGS. 1 to 4.

Reference numeral 1 designates the mattress body, which is composed of upper and lower cushion layers 2.3, an intermediate retention layer 4, and an integrated cover 5 that integrally covers the upper and lower cushion layers 2, 3 and the intermediate retention layer 4.

The upper cushion layer 2 is made of breathable elastic bodies 8, 9 made of polyurethane resin foam having a large number of chevron-shaped protrusions 6.7 on the upper surface.
are stacked in two layers, upper and lower, with a breathable sheet 10 made of water-permeable and breathable nonwoven fabric interposed in the middle, and the breathable sheet 10 is fixed to the lower surface of the upper breathable elastic body 8 by adhesion or welding. The flexible sheet 10 is supported in contact with the chevron-shaped protrusion 7 of the lower breathable elastic body 9.

The lower cushion layer 3 has the same structure as the upper cushion layer 2, but the upper cushion layer 2 is turned inside out.

The intermediate holding layer 4 is made of ABS resin (acrylonitrile butadiene styrene copolymer resin), and is a corrugated bending plate made of a material that has a strong resilient restoring force against distortion and bending, and is rich in repeatability.

The intermediate holding layer 4 has ventilation passages 11 with both ends open in a direction perpendicular to the pitch direction of the corrugations, and ventilation holes 1 at appropriate intervals between the tops 12 and bottoms 13 of each corrugation.
4 is formed.

Moreover, the curvature of the wave-shaped top part 12 and bottom part 13 is made large and small, so that the contact area of the intermediate holding layer 4 with the body differs between the front side and the back side of the main body 10.

Reference numeral 15 denotes a shape-retaining plate, which is made of a flexible synthetic resin elongated plate and is placed in contact with the upper and lower surfaces of the intermediate holding layer 4 in a direction perpendicular to the direction of the pitch of the waveform. They are fixed by welding or gluing, respectively, to keep the pitch of the waves constant.

Reference numeral 16 denotes both end holding members, which are prismatic bodies made of polyurethane resin foam, and have a thickness that is approximately equal to the height of the corrugations of the intermediate holding layer 4, and a length that is approximately equal to the width (length in the direction perpendicular to the pitch of the corrugations). It is attached to both ends of the intermediate holding layer 4.

Reference numeral 17 denotes a wave-shaped shape-retaining frame, which is made of a flexible synthetic resin material, and is connected to both ends of the wave-shaped intermediate retaining layer 4, that is, one of the ventilation passages 11.
A wave-shaped end plate portion 18 that is fitted in series facing both ends of
．． 18, and a connecting portion 19.19 that connects the end plate portions 18.18, and air intake/exhaust holes 20 are opened for each ventilation path 11 in the end plate portions ia, is.

The cover unit 5 is a cloth bag body, which has a window hole 21 opened to expose the central part of the upper and lower surfaces of the pinerest body 1, covers the body 1 in a frame shape, and connects the upper and lower cushion layers 2, 3 and the middle part. The holding layer 4 is integrally wrapped and bonded.

The plurality of main bodies 1 are connected in series by the connecting parts 22 of the cover unit 5, and the connecting parts 22 are arranged alternately at the upper and lower ends of the end surface of the main body 1.

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

When in use, cover the body with a sheet or the like and lie directly on the breathable elastic body 8 on the surface.

The uppermost breathable elastic body 8 absorbs sweat, moisture, and the like.

The breathable elastic body 8 that has absorbed moisture is pulled out together with the breathable sheet 10 through the window hole 21 of the cover unit 5 and replaced.

In addition, the upper breathable elastic body 8 is replaced by the lower breathable elastic body 90.
Since it is supported on the chevron-shaped protrusion 7, there is a space between the upper and lower breathable elastic bodies 8 and 9 around the chevron-shaped protrusion 7, and a large amount of space exists between the upper and lower breathable elastic bodies 8 and 9. The presence of air increases the cushioning properties and serves as a passageway for removing moisture-absorbed air and for inhaling outside air.

In addition, since the upper and lower cushion layers 2 and 3 are provided with upper and lower two layers of breathable elastic bodies 8, 9, 8, and 9, respectively, soft cushioning properties can be obtained.

Next, since the intermediate holding layer 4 is made of a flexible plate bent in a corrugated manner, the weight of the body is supported at its top 12 via the upper cushion layer 2, and the body fits into the upper cushion layer 2. Prevent this from happening and maintain a normal posture.

Further, since it is supported by the top portion 12 having a large curvature, no local hard stimulation is applied to the body.

Furthermore, when the upper cushion layer 2 is pushed due to movement of the body or the like, the air in the two-stage breathable elastic body 8°9 is discharged to the ventilation passage 11 of the corrugated bending plate interposed inside the air passage. 11 directly or through the intake/exhaust hole 20, and conversely, the outside air passes through the ventilation path 11 and enters the breathable elastic body 8.
．． 9, and the inside of the upper cushion layer 2 is always kept dry.

In addition, when the chevron-shaped protrusion 6 that protrudes downward from the breathable elastic body 8 at the lowest stage protrudes from the window hole 21 of the cover unit 5, and the support frame 24 of the bed 23 is tiltable as shown in FIG. It engages with the gap between the slat-shaped support plates 25 of the frame 24, and when the pine-tress body 1 is tilted, the pine-tress body 1 is held so as not to move.

Further, the shape of the breathable elastic body 8 is maintained by the breathable elastic body 10, and when it is inserted through the window hole 21 of the cover unit 5 during replacement, it is easy to stack it on the breathable elastic body 9 in the lower stage. .

[Effect of idea]

According to the present invention, upper and lower cushion layers are formed by overlapping two upper and lower layers of breathable elastic bodies having a large number of chevron-shaped protrusions, and an intermediate support made of a flexible wave-shaped bending plate is formed between the upper and lower cushion layers. This intermediate retaining layer can be ventilated in the direction perpendicular to the pitch direction of the corrugations, and has a large number of ventilation holes between the top and bottom of the corrugations, so that the upper and lower cushioning layers can Each breathable elastic body is stacked in two layers, upper and lower, and each breathable elastic body has a large number of chevron-shaped protrusions, so it has a soft and cushioning property as a whole, and it prevents pressure on the cortical layer that causes pressure sores. 5 blood can be prevented.

In addition, the upper breathable elastic body can absorb sweat and moisture, and the upper breathable elastic body that absorbs sweat or moisture or becomes dirty can be replaced together with this inner breathable sheet to keep it clean at all times. can be kept.

Furthermore, the intermediate holding layer is a core material that is flexible and hard in the vertical direction, preventing the body from getting stuck in the cushion layer made of multilayered breathable elastic material, maintaining a normal posture, and supporting the wavy top. By supporting your body, you can reduce the pressure on your body.

Furthermore, moisture from the cushion layer is removed by ventilation in a direction perpendicular to the corrugations of the intermediate retention layer, and conversely, outside air is guided to the entire cushion layer, preventing the cushion layer from becoming damp. The prevention effect can be further improved.

Further, the downwardly projecting chevron-shaped projection of the breathable elastic body at the lowest stage serves as a retaining piece for the bed, and can act to prevent slipping when the bed frame is raised and lowered.
