Figs. 1 (a), (b), and (c) are perspective views each showing a platform mattress according to an embodiment of the present invention.

Figures 2 (a), (b), and (c) are perspective views each showing a platform mattress according to an embodiment of the present invention.

Fig. 3 is an external view of a platform mattress according to an embodiment of the present invention.

Hereinafter, a platform mattress and a method of using the same according to the embodiments of the present invention will be described. 1 (a) and 2 (a) are views showing the lower mattress member 1. As shown in FIG. The lower mattress member 1 is composed of a first member 2 having a width and a length corresponding to the entire surface of the bed, and second members 3 and 4 joined to the head side and the foot of the first member 2 The third member 6 is joined to the upper part of the waist portion of the first member 2; and the fourth member 5 is joined to the third member 6 of the first member 2 and the second member on the foot side in a plan view. Below the part between the members 4. The upper surfaces of the first member 2 and the third member 6 are substantially on the same surface, and the lower surfaces of the second members 3, 4 and the fourth member 5 are approximately on the same surface as the lower surface of the waist portion of the first member 2. Therefore, the lower mattress member 1 is formed into a plate shape as a whole. The first member 2 is made of, for example, a hard polyester sponge having a hardness of 200N (40% compression) or higher, and the second member 3, 4 and the third member 6 are, for example, 50N to 130N (40% compression). ). Although the fourth member 5 is also made of urethane, its hardness is 150N to 500N (40% compression), making it harder than the second members 3, 4 and the third member 6. The first member 2 made of rigid polyester sponge serves as the basic structure of the lower mattress member 1 Materials. The third member 6 corresponding to the waist is formed of a softer material, and the fourth member 5 corresponding to the thigh is formed of a harder material.

The upper mattress member 10 is detachably superimposed on the lower mattress member 1 as shown in Figs. 1 (b) and 2 (b). This upper mattress member 10 has the same planar shape (width and length) as the lower mattress member 1, and is composed of a fifth member 11 in the central portion and a sixth member 13 at both ends in the width direction. . The fifth member 11 is made of, for example, urethane having a hardness of 50N to 130N (40% compression), and the sixth member 13 is also made of, for example, urethane, but has a hardness of 150N to 500N. (40% compression), making it harder than the fifth member 11 in the center. The surface of the fifth member 11 is subjected to a roughening treatment 12. The upper mattress 10 is, for example, a flat fastener fastened to a part of the lower mattress. When the upper mattress 10 is used as the material of the upper mattress member 1 and has the function of the flat fastener, the upper mattress member 10 and the lower mattress are used. The mattress members 1 are detachably locked by the flat fasteners and can be fixed to each other. For example, the third member 6 of the lower mattress member 1 can be formed by using a film-removed urethane as a function of the flat fastener having the lower mattress member 1. The de-membrane urethane refers to removing a thin film from the structure of a general urethane foam in order to improve the water flowability during washing and the air permeability during drying. The backbone urethane is left behind. Thereby, the third member 6 has a function as a flat fastener on the upper surface thereof, and between the third member 6 and the flat fastener below the upper mattress member 10, the upper mattress member 10 and the lower member The mattress members 1 can be locked to each other.

FIG. 3 is a perspective view showing the cover 40 according to the present embodiment. As shown in FIG. 3, the outer cover 40 is formed in a bag shape to store the laminated body of the lower mattress member 1 and the upper mattress member 10 inside. The lower mattress member 1 and the upper mattress member 10 are Its coated. A buckle 41 is provided at the end portion of the bed of the cover 40 in the longitudinal direction and a part of both sides connected thereto, and the lower mattress member 1 and the upper mattress member 10 are housed inside by opening and closing the fastener 41. . The cover 40 is provided with two pairs of handles 42 on both sides thereof, which is convenient for carrying the mattress. For example, the upper portion 40 a of the outer cover 40 is a knitted product, and the lower portion 40 b is a fabric product, and is joined at the side of the outer cover 40. In addition, a logo or the like of a product can be displayed on the upper surface 40a by silk printing.

1 (c) and 2 (c) show another upper mattress member 20. As shown in FIG. The upper mattress member 20 includes two members, a seventh member 21 and an eighth member 22, which are arranged side by side in the longitudinal direction of the bed at the center in the width direction of the bed. The portion of the eighth member 22 having a uniform thickness and the portion of the inclined surface 23 that gradually decreases in thickness and has an inclined upper surface are connected in the longitudinal direction of the bed. The ninth member 24 and the tenth member 25 are arranged on the flat surfaces of the seventh member 21 and the eighth member 22, and the eleventh member 26 is arranged on the inclined surface 23 of the eighth member 22. The ninth member 24, the tenth member 25, and the eleventh member 26 all have a uniform thickness. A twelfth member 27 extending along the entire length of the bed in the widthwise direction of the seventh member 21 and eighth member 22 is arranged on both sides of the bed, and the twelfth member 27 is arranged facing the bed. 13th member 28 extending in the long-side direction. The seventh to thirteenth members 21 to 28 are integrally joined to each other. The seventh member 21, the ninth member 24, the tenth member 25, and the eleventh member 26 are made of, for example, urethane having a hardness of 50 to 130 N (40% compression), and the eighth member 22 is For example, it is made of urethane having a hardness of 150 to 500 N (40% compression). In addition, the twelfth member 27 is made of, for example, a hard polyester sponge having a hardness of 200N (40% compression) or more, and the thirteenth member 28 is, for example, a urethane having a hardness of 50 to 130N (40% compression). Made of ethyl ester. The upper mattress member 20 has a double-layer structure, and the hardness of the position on the mattress can be adjusted arbitrarily and widely.

In addition, the lower mattress member 1 has only functions required as a mattress above the bed. Therefore, the lower mattress member 1 has functions required in common for various patients and the like, and has a function as a mattress for a patient to lie on, even if only the minimum sleep comfort is provided. As described above, the lower mattress member 1 is not only easy to move for a patient lying on his back, but also has excellent dispersibility of body pressure on the buttocks. The lower mattress member 1 shown in FIG. 1 (a) can be called a thin type mattress, for example, having a thickness of 7 cm. The standard flat mattress of the combined lower mattress member 1 and the upper mattress member 10 shown in FIG. 1 (b) has a thickness of, for example, 9 cm, and the combined lower mattress member shown in FIG. 1 (c). 1 and the upper mattress member 20 have a thickness of, for example, 12.5 cm. As described above, since the thickness of the upper mattress member is different, it is preferable to prepare the outer cover 40 corresponding to various thicknesses. That is, although the upper mattress member has a function added depending on the user of the bed such as a patient, that is, for each bed, The function required by the user, but since the thickness of the entire mattress varies due to the thickness of the upper mattress member, it is better to prepare a suitable cover corresponding to it.

In the present embodiment configured as described above, as shown in FIGS. 1 (b) and 2 (b), the upper mattress member 10 is superimposed on the lower mattress member 1, and The fastener 41 of the outer cover 40 is opened, and the laminated body of the upper mattress member 10 and the lower mattress member 1 is stored in the outer cover 40. After that, the buckle 41 is closed so that the upper mattress member 10 and the lower mattress member 1 are stored in one body, and then the mattress is carried to the frame of the bed by the handle 42 for use. The mattress has a lower mattress member 1 having a common function as a mattress for everyone, or a minimum function as a bedding, even if only the lower mattress member 1 is used. Use as a mattress. In addition, the upper mattress member 10 has a function that is not sufficient for the user of each bed only by the lower mattress member 1, that is, the inherent function required for the user of each bed. Functions that cannot be obtained by the lower mattress member 1 alone.

The first mattress member 1 of Figs. 1 (a) and 2 (a) has a first member 2 formed by a hard polyester sponge having a hardness of 200N or more. Although the first member 2 is disposed on the bed, The entire area in the longitudinal direction, but because of the waist of the user lying on the bed, the first member 2 is provided with a third member 6 made of a softer urethane having a hardness of 50 to 130N. Therefore, the back and feet of the user of the bed will be supported by the harder material, and the waist will be supported by the softer material. Therefore, the lower mattress member 1 of this embodiment has the following characteristics: It is easy to sink, and it is not easy to sink the back and feet.

In addition, the upper mattress member 10 has the following characteristics: when the patient adopts a sitting posture in which the patient sits at the end in the width direction of the bed to leave the bed, the hardness of the sixth member 13 at the end of the upper mattress member 10 It is higher than the center, so the patient can easily leave the bed. In the upper mattress member 10 disposed on the lower mattress member 1, the central portion in the width direction of the upper mattress member 10 is spread across the longitudinal direction by a fifth member 11 made of a softer urethane having a hardness of 50 to 130N. It is arranged over the entire area of the device, so the relative soft-hard relationship supported by the lower mattress member 1 does not change. That is, as the mattress composed of the upper mattress member 10 superposed on the lower mattress member 1, the back and feet of the user of the bed are supported by relatively hard materials, and the waist is relatively Supported by soft materials.

As described above, when the user (patient) of the bed lies on his back, his waist (hips) is positioned on the laminated body configured as follows: The lowermost layer is a harder first member having a hardness of 200N or more. 2, and above it is the fifth member 11 having a hardness of 50 to 130N and the third member 6 having a hardness of 50 to 130N, so it is actually supported by the urethane having a hardness of 50 to 130N. In addition, since the patient's back is located on a laminate configured as follows: the second member 3 having a hardness of 50 to 130N is placed on the lowest layer, and the stacking hardness is harder than 200N (40% compression) The hard polyester sponge is composed of the first member 2, and the fifth member 11 having a hardness of 50 to 130N. Therefore, the harder first member 2 is more affected, and the back is harder than the waist (hip). Part of it. The feet are supported by the same rigidity as the back. again It is because the patient's thigh is located on a laminate configured as follows: a fourth member 5 having a hardness of 150 to 500N, a first member 2 made of a hard polyester sponge, and a hardness between The fifth member 11 from 50 to 130N is supported by a stiffer member than the waist, and also by a stiffer member than the back and feet.

As described above, when a mattress in which the lower mattress member 1 and the upper mattress member 10 are laminated is used, the patient's buttocks are supported by the softest part (the hardness is 50 to 130N), and The back and feet are supported by harder parts than the hips, and the thighs are supported by harder parts than the back and feet. Therefore, the mattress not only makes the patient easy to turn over during sleep, but because the patient's buttocks are supported by the hardness of 50 to 130N, the body pressure dispersion is excellent, so that both sleep comfort and body pressure dispersion are achieved. Good balance. In addition, since the sixth member having a hardness of 150 to 500 N is disposed in this part when the sitting posture is adopted on the bed, as described above, the patient can easily leave the bed. Therefore, by combining the lower mattress member 1 and the upper mattress member 10, it is possible to obtain a standard mattress that has excellent sleeping comfort and body pressure dispersion, and can maintain stability when adopting an end-seated posture.

On the other hand, when the upper mattress member 20 is used instead of the upper mattress member 10 to be combined with the lower mattress member 1, the seventh member 21 having a hardness of 50 to 130N and the eighth member 22 having a hardness of 150 to 500N The eighth member 22 having a hardness of 150 to 500N is arranged in the longitudinal direction of the bed, and the thickness of the inclined surface 23 gradually decreases toward the longitudinal direction of the bed, so the hardness also gradually decreases. So make When the upper mattress member 20 is used, the hardness changes in the longitudinal direction of the bed. That is, the user of the bed will be supported by the softer seventh member 21 and the buttocks by the relatively harder eighth member 22. The hardness of the eighth member 22 will be closer to the foot side. And gradually lower. In addition, the upper mattress member 20 has a double-layered structure, and the softer 9th member 24, 10th member 25, and 11th member 26 are disposed on the upper layer, so that the user of the bed feels comfortable. structure. In addition, since the hardness of the eighth member 22 of the buttocks is hard, it is possible to prevent the buttocks from hitting the lower mattress member 1 even when the relatively heavy buttocks of the human body sink into the upper mattress member 20. It is the so-called love story. In addition, when the upper mattress member 20 is used, since the position of the bed is high in the sitting posture, the sitting posture is stabilized. For example, a rehabilitation patient may change the posture when taking the sitting posture. Stand up easily. However, unlike the upper mattress member 10, when the upper mattress member 20 is used, the part in the sitting posture is formed into a double-layer structure. Although the hardness of the lower twelfth member 27 is 200N or more, The hardness of the 13th member 28 on the upper layer is softened from 50 to 130N, so that it is formed into a structure that makes the user of the bed feel comfortable.

Furthermore, when the upper mattress member 20 is used, as described above, not only the end sitting posture is stable, but also when the supine posture or the side lying posture is adopted, or when the backrest is raised below 30 ° It is also possible to obtain excellent body pressure dispersibility. The upper mattress member 20 has a double-layer structure and has a thickness of, for example, 12.5 cm. Since the upper mattress member 20 is 3.5 cm thicker than the single-layered upper mattress member 10 (for example, 9 cm thick), The area of contact with the user of the bed also becomes greater than that of the upper mattress member 10. Therefore, when using a mattress in which the upper mattress member 20 and the lower mattress member 1 are combined, not only the body pressure dispersibility is extremely excellent, but also the occurrence of bedsores is extremely effectively prevented. That is, the mattress is formed into a bedsore-prevention type mattress having the following functions: excellent dispersibility of body pressure when the patient is in a supine posture, a lateral lying posture, and when the backrest is lifted. Furthermore, when the upper mattress member is made softer and thicker, it can be formed into a structure that makes the contact area with the patient's body larger and the body pressure dispersibility better, and can be assembled to effectively prevent bedsores mattress.

As described above, according to the inherent characteristics of the user of the bed, an upper mattress member having a desired function is selected, and it is combined with a lower mattress member 1 for common use to obtain desired characteristics. Mattress. In the case of a general patient, the upper mattress member 10 is used, and in the case of a patient with severe bedsore, the upper mattress member 20 is used. The lower mattress member 1 is common to all patients. Therefore, in this embodiment, since only the upper mattress member needs to be exchanged to obtain the function required according to the inherent characteristics of the patient, it is not necessary to prepare a special mattress having the function in advance. For hospitals and nursing institutions, Can reduce equipment costs. Even in the case of home care, the state of the caretaker changes monthly or annually. There may be caregivers who have not suffered from bedsores. As the years go by, the bedsores become serious. Even if the above conditions change, you can obtain the characteristics that are most suitable for this time by replacing the upper mattress. mattress. Therefore, the cost required for care can be saved. As described above, in this embodiment, only the upper mattress member By converting into appropriate components, it is possible to add the special functions required by the patient to the functions of the inherent characteristics required by the user of the bed. Therefore, it is possible to easily and inexpensively obtain a bed having the best function for the user of the bed. The pads can also significantly reduce the cost for customizing the mattresses described above.

[Industrial availability]
