[Industrial applications]

 The present invention relates to a pressure ulcer prevention cushion body used for pressure ulcer prevention and treatment.

[0002]

[Prior art]

 Conventionally, in the field of medical care, various cushion bodies have been used to prevent pressure ulcers in the care of the injured in the bed.

The conventional cushion structure includes a fluid type such as a water bed and an air cushion in which various fluids are enclosed in an airtight bag, and an elastic body having a rich cushioning property such as a sponge pillow. There was a solid type used.

The fluid type cushion body attempts to disperse the pressure by utilizing the fact that the buoyancy acting on the solid on the fluid is uniform in all parts. The solid cushion body tries to support the pressing force by the physical restoring force of the solid body.

Recently, what is called a flotation pad in which a semi-fluid gel polymer is enclosed in a bag has been used. The flotation pad has a property that a gel-like substance is intermediate between liquid and solid, and since it has both fluidity and elasticity, it has pressure dispersibility due to fluidity, and it also recovers due to elasticity. It also has excellent characteristics in that it has excellent cushioning properties not only for vertical loads but also for horizontal loads. However, the above flotation pad has the following problems.

When a gel-like material is pushed to the periphery and moved by long-term pressing, the gel under the load receiving portion becomes thin and a bottoming feeling occurs, and the elastic recovery of the gel is delayed, and a cushioning feeling is generated. Is insufficient, and the desired pressure ulcer effect cannot be obtained.

[Problems to be solved by the device]

 The present invention provides a pressure ulcer cushion body that simultaneously solves the above problems.

[0008]

[Means for Solving the Problems]

Means of the present invention for solving the problems include a thickness of 30 mm or more, a stress S ₂₅ at 25% compression of 0.02 Kgf / cm ² or less, and a stress S ₇₅ at 75% compression of 0.08 Kg f / cm ² The foam having the above ratio and the ratio of S ₇₅ / S ₂₅ of 5 or more is housed in a rigid frame body having a concave recess for containing the foam body, and the foam body and the outside of the frame body are covered with a cover material. By making a coated body.

【Example】

 Preferred embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 shows a pressure ulcer cushion body of the present invention and a mode of use thereof. As shown in (a), a plate-shaped foam body having a size that fits in the recess is put in the recess 21 of the rigid frame body 20. Here, the frame body prevents the foamed body contained therein from spreading laterally and being unable to support the pressure, and may be made of any material as long as it has a certain rigidity. For example, a hard urethane foam is preferable because it is lightweight and has rigidity. On the other hand, the foam must be a material that has a soft touch, has sufficient cushioning properties, and does not cause excessive sinking. For this reason, it is preferable to use a material that responds as little as possible at low compression and generates a certain amount of impact resilience at high compression. As a result of various studies, a thickness of 30 mm or more, a 25% compressive stress S ₂₅ of 0.02 Kgf / cm ² or less, a 75% compressive stress S ₇₅ of 0.08 Kgf / cm ² or more, and S It has been found that the ratio ₇₅ / S ₂₅ is preferably 5 or more, and only the silicone resin continuous foam satisfies this property.

FIG. 2 shows the silicone resin continuous foam of this embodiment (size: 300 mm × 400 mm, thickness: 100 mm / s, compression rate: 50 mm / s, according to JIS K6401, Section 5.4, hardness test evaluation method. 38 mm) compression stress measurement results are shown. As a result, S ₂₅ was 0.015 Kgf / cm ² and S ₇₅ was 0.11 Kgf / cm ² , which satisfied the above conditions, and the tactile sensation during actual use was also favorable.

As shown in FIG. 1 (b), an actual use mode of the pressure ulcer cushion body of the present invention is to put a foam in a concave recess of the frame (at this time, the surface of the foam is slightly It is preferable that it protrudes from the body.) It is preferable that the surface is covered with a surface material 30 such as cotton cloth, which has a soft feel and is hygroscopic. The human body M is supported by the foam of the pressure ulcer cushion body.

[0013]

[Effect of device]

 The pressure ulcer cushion body of the present invention has an extremely soft touch and has sufficient resilience. Since the soft foam is contained in the rigid frame, the foam does not have a sideways escape due to the pressing force, so it is efficient and the volume of foam can be reduced.
