Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mattress for a gatch bed that does not shift with respect to the back bottom of the bed when raising the back of the gatch bed.

A mattress is placed on the bottom of the gatch bed, and a bed user such as a patient lies down on the mattress. In the Gatch bed, the bottom corresponds to the back bottom corresponding to the user's back, the waist bottom corresponding to the waist, the knee bottom corresponding to the thigh, and the foot. Although it is divided into a foot bottom and the waist bottom is usually fixed, the back bottom swings around the waist bottom side end as a center of rotation. When the back bottom is raised and a back raising operation is performed, the upper half of the user's body on the mattress is raised, and the user is in a position that facilitates reading or watching television.

However, in the case of such a Gatch bed, when the back raising operation is performed, the user's body on the mattress is likely to be displaced in the longitudinal direction (foot direction) of the bed, which makes it uncomfortable to sleep and requires extra force. However, there is a problem in that it affects the user.

Further, when the back is raised, the stress applied to the body also acts on the mattress on the back bottom so as to shift in the bed longitudinal direction (foot direction). Therefore, the displacement of the mattress becomes a problem.

Therefore, Patent Document 1 discloses a mattress in which a sheet member having a high friction coefficient is laid between the back surface of the mattress and the upper surface of the bed (bottom), and slip resistance is added to the slip of the mattress. There is.

However, the mattress disclosed in Patent Document 1 can prevent sliding of the mattress in the longitudinal direction of the bed, but can prevent displacement of the bed user lying on the mattress in the longitudinal direction of the bed. There is a problem that it is not a thing.

The present invention has been made in view of the above problems, and it is possible to prevent the displacement of the mattress in the longitudinal direction of the bed during the back raising operation of the Gatch bed and the displacement of the bed user lying on the mattress. The purpose is to provide a mattress for use.

The mattress for a Gatch bed according to the embodiment includes a mattress body that supports the weight of the bed user, and a cover that encloses the mattress body. The mattress body comprises a portion corresponding to the knee bottom Gyatchibeddo, the portion corresponding to the waist bottom of the Gyatchibeddo, a first member, a. The portion corresponding to the knee bottom includes a fourth member below the first member. The portion corresponding to the waist bottom includes a third member above the first member. The hardness of the fourth member is harder than the hardness of the third member. A part of the lower surface of the first member is flush with the lower surface of the fourth member. A part of the upper surface of the first member is flush with the upper surface of the third member.

In the present invention, when the mattress body has a hard portion, the back bottom rises, and when the back raising operation is performed, the weight of the user who tries to shift in the longitudinal direction of the mattress falls to the hard portion of the mattress body. Easy to concentrate. Therefore, when the mattress main body is configured such that the position of the waist is soft and the position of the thigh is hard, for example, a bed user lying on the mattress has a relatively lower waist, but The part is supported by a hard material and does not sink easily. Therefore, it is possible to prevent the bed user himself/herself from shifting in the foot direction with respect to the mattress body during the back raising operation. Further, by providing a slip stopper at a position corresponding to the hard portion of the mattress main body on the lower surface of the cover, a load is effectively applied to this slip stopper, and a frictional force is effectively generated between the slip stopper and the bottom below. This prevents the mattress from shifting in its longitudinal direction.

It is a perspective view showing a mattress for a Gatch bed concerning an embodiment of the present invention. Similarly, it is a side view. Similarly, it is a bottom view showing the bottom surface of the cover. It is a figure which shows the modification of a mattress main body, (a) is an assembly perspective view, (b) is a side view. It is a figure which shows the other modification of a mattress main body, (a) is an assembly perspective view, (b) is a side view.

Hereinafter, a mattress for a gatch bed according to an embodiment of the present invention will be described. FIG. 1 is a perspective view of the mattress body 1, and FIG. 2 is a side view. In the Gatch bed, a back bottom, a waist bottom, a knee bottom, and a foot bottom are usually arranged in the longitudinal direction of the bed, and the waist bottom is fixed. The back bottom swings the end on the waist bottom side with respect to the waist bottom. It swings around the center. The knee bottom and the foot bottom constitute a leg bottom, and in many cases, they can individually and independently swing, but the leg bottom is not divided into a knee bottom and a foot bottom, It may be fixed integrally. The back bottom supports the bed user's back, and the waist bottom supports the waist. Therefore, the thigh of the bed user is supported by the knee bottom or the leg bottom.

The mattress body 1 has a first member 2 having a width and a length corresponding to the entire surface of the bed, and second members 3, 4 joined to the lower surfaces of the head-side and foot-side portions of the first member 2. A third member 6 joined to the upper surface of the waist portion of the first member 2 and a lower surface of the first member 2 between the third member 6 and the foot side second member 4 in plan view. It is composed of the joined fourth member 5. The upper surfaces of the first member 2 and the third member 6 are substantially flush with each other, and the lower surfaces of the second members 3, 4 and the fourth member 5 are substantially flush with the lower surface of the waist portion of the first member 2. is there. Therefore, the mattress body 1 has a plate shape as a whole. The first member 2 is made of, for example, polyester hard cotton having a hardness of 200 N (40% compression) or more, and the second members 3 and 4 and the third member 6 have a hardness of 50 to 130 N (40%). Compressed) made of urethane. Similarly, the fourth member 5 is made of urethane, but has a hardness of 150 to 500 N (40% compression), and has a higher hardness than the second members 3, 4 and the third member 6. The first member 2 made of polyester hard cotton serves as a basic structural material of the mattress body 1 and is a base material extending in the entire longitudinal direction of the bed. Further, the third member 6 corresponding to the waist is made of a slightly soft material. On the other hand, the fourth member 5 corresponding to the thigh is formed of a hard material and is an auxiliary material formed of a material that is harder than the base material or the third member 6 of the waist. As shown in FIG. 2, the cross-sectional shape of this auxiliary member, that is, the fourth member 5, is a wedge-shaped portion on the waist side, and a flat-shaped portion on the foot side having a uniform thickness. .. This auxiliary material preferably has a length of 100 mm or more in the longitudinal direction of the bed and a width of 150 mm or more.

FIG. 3 is a bottom view showing the cover 40 of this embodiment. As shown in FIG. 3, the cover 40 has a bag shape, the mattress body 1 is housed therein, and the mattress body 1 is encapsulated. Fasteners 41 are provided on the edges of the cover 40 in the longitudinal direction of the bed and a part of the edges on both sides following the edges. By opening and closing the fasteners 41, the mattress body 1 is housed inside. Two pairs of handles 42 are provided on both sides of the cover 40 to facilitate the transportation of the mattress. For example, the cover 40 has an upper half part made of knit and a lower half part made of woven fabric, and the upper half part and the lower half part are joined at a side part of the cover 40 to form a bag shape. ing. A product logo or the like can be displayed on the upper surface of the cover 40 by silk printing.

A non-slip portion 43 is formed on the lower surface of the cover 40 by anti-slip processing on a portion corresponding to the hard fourth member 5, that is, a portion corresponding to the thigh of the bed user lying on the mattress. It is provided. The anti-slip process of the anti-slip part 43 can be performed by applying a rubber material in a flat shape, but this means can take various other means. It is preferable that the anti-slip portion 43 has a length of 100 mm or more in the bed longitudinal direction and a width of 150 mm or more.

In the mattress of the present embodiment configured as described above, the auxiliary material (fourth member 5) is formed of a hard material of 150 to 500 N, and the third member 6 supporting the lumbar region is a soft material of 50 to 130 N. Since the waist of the bed user is relatively easily sunk by the third member 6, the auxiliary member (fourth member 5) for supporting the thigh is made of a hard material of 150 to 500 N. Therefore, the thigh of the bed user is supported by the auxiliary material (the fourth member 5) and does not sink relatively. Therefore, the user's buttocks (waist) are locked by the auxiliary member (fourth member 5) and are not displaced in the bed longitudinal direction (foot direction). Further, since the cover 40 is provided with the non-slip processing portion 43, a large frictional force acts between the mattress itself and the knee bottom (leg bottom) to cause a shift in the longitudinal direction of the bed. There is no. Furthermore, when the bed user sits on the mattress, the buttocks receive a reaction force from the auxiliary material (fourth member 5), and the pelvis easily stands.

In the mattress body 1, the first member 2 is formed of polyester hard cotton having a hardness of 200 N or more, and the first member 2 is arranged in the entire area in the longitudinal direction of the bed, but is laid down on the bed. Since the third member 6 made of soft urethane having a hardness of 50 to 130 N is arranged on the first member 2 in the waist portion of the person, the back and legs of the bed user are supported by a hard material. The waist is supported by the soft material. Therefore, the lower mattress member 1 of the present embodiment has characteristics that the waist portion is likely to sink and the back portion and the leg portions are unlikely to sink.

FIG. 4 is a diagram showing a modified example of a mattress in which the mattress body 1 and the upper mattress member 10 are laminated. As shown in FIG. 4, the upper mattress member 10 is separably stacked on the mattress body 1. The upper mattress member 10 has the same planar shape (width and length) as the mattress body 1, and is composed of a fifth member 11 at the central portion and sixth members 13 at both ends in the width direction. The fifth member 11 is, for example, made of urethane having a hardness of 50 to 130 N (40% compression), and the sixth member 13 is also made of urethane, for example, but has a hardness of 150 to 500 N (40% compression). ), and it is harder than the fifth member 11 in the central portion. Further, the surface of the fifth member 11 is subjected to a roughening treatment 12. In this case, the upper mattress member 10 and the mattress body 1 are housed in the cover 40 in a stacked state. In the upper mattress 10, for example, a surface fastener is bonded to a part of the lower surface of the mattress, and when a material having a function of a surface fastener is used as the material of the upper surface of the mattress body 1, the upper mattress member 10 and the mattress body 1 are The surface fasteners can be separably locked and fixed to each other. The third member 6 of the mattress body 1 may be formed of, for example, urethane without a film, which has a function of a surface fastener of the mattress body 1. This filmless urethane refers to urethane in which a small film in the structure of a normal urethane foam is skipped to leave only the skeleton in order to improve water flow during washing and air permeability during drying. As a result, the upper surface of the third member 6 functions as a surface fastener, and the upper mattress member 10 and the mattress body 1 are mutually locked between the third member 6 and the surface fastener on the lower surface of the upper mattress member 10. You can

Also in the case of this mattress, the same effect as that of the mattress shown in FIG. 1 is obtained. That is, the user's buttocks (waist) are locked by the auxiliary member (fourth member 5) and are not displaced in the bed longitudinal direction (foot direction). Further, since the cover 40 is provided with the non-slip processing portion 43, a large frictional force acts between the mattress itself and the knee bottom (leg bottom) to cause a shift in the longitudinal direction of the bed. There is no. Furthermore, when the bed user sits on the mattress, the buttocks receive a reaction force from the auxiliary material (fourth member 5), and the pelvis easily stands.

However, in this mattress body, the hardness of the mattress can be variously adjusted by the upper mattress member 10, and the sleeping comfort can be improved. That is, in the case of this mattress, the sixth member 13 at the end of the upper layer mattress member 10 is provided when the patient sits at the end of the bed in the width direction and assumes the end sitting position in which the patient is about to leave the bed. Since the hardness of the is higher than that of the central part, the patient can easily get out of bed. In the upper mattress member 10 arranged on the mattress body 1, the central portion in the width direction is occupied by the soft urethane fifth member 11 having a hardness of 50 to 130 N over the entire area in the longitudinal direction. Therefore, the relative hardness relationship of the support by the mattress body 1 does not change. That is, as a mattress in which the upper mattress member 10 is overlaid on the mattress body 1, the back and legs of the bed user are supported by a relatively hard material, and the waist is supported by a relatively soft material.

In this way, when the bed user (patient) lays on the bed, the lumbar region (buttock) has a hard first member 2 having a hardness of 200 N or more in the lowermost layer, and the hardness is higher than that. Since the laminated body of the fifth member 11 having a hardness of 50 to 130N and the third member 6 having a hardness of 50 to 130N is located above the laminated body, it is substantially supported by urethane having a hardness of 50 to 130N. The back of the patient has a second member 3 having a hardness of 50 to 130 N at the lowermost layer and a first member 2 made of hard polyester cotton having a hardness of 200 N (40% compression) or more and a hardness of 50. Since the laminated body with the fifth member 11 of 130N to 130N is arranged, it is strongly influenced by the hard first member 2 and is supported by a member harder than the waist (buttock). The legs are supported by the same hardness as the back. Further, the thigh of the patient is on the laminated body of the fourth member 5 having a hardness of 150 to 500 N, the first member 2 made of polyester hard cotton, and the fifth member 11 having a hardness of 50 to 130 N. Since it is located at, it is supported by a member harder than the waist and the back and legs. In this way, the buttocks are supported by the softest member (hardness 50 to 130N), the back and legs are supported by a member harder than the buttocks, and the thighs are supported by a member harder than the members of the back and legs. Will be done. Therefore, this mattress is easy for the patient to turn over, and since the patient's buttocks are supported by the member having a hardness of 50 to 130 N, the body pressure dispersibility is excellent, and the sleeping comfort and the body pressure dispersibility are excellent. Both are excellent and well balanced. Moreover, as described above, the patient easily leaves the bed. Therefore, the combination of the mattress main body 1 and the upper layer mattress member 10 is a standard type mattress having the functions of excellent sleeping comfort and body pressure dispersibility and stable end sitting.

FIG. 5 shows another upper mattress member 20. The upper mattress member 20 has two seventh members 21 and eight members 22 arranged side by side in the bed longitudinal direction at the center in the bed width direction. The eighth member 22 has a portion having a uniform thickness and a portion whose thickness gradually decreases and the upper surface thereof is an inclined surface 23, which are continuous 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. Has been done. The ninth member 24, the tenth member 25, and the eleventh member 26 have a uniform thickness. A twelfth member 27 extending over the entire length in the bed longitudinal direction is arranged on both sides of the seventh member 21 and the eighth member 22 in the bed width direction. A thirteenth member 28 extending in the direction is arranged. The seventh member 21 to the thirteenth member 28 are joined to each other and integrally configured. The seventh member 21 is, for example, made of urethane having a hardness of 50 to 130 N (40% compression), and the eighth member 22 is, for example, urethane having a hardness of 150 to 500 N (40% compression). The ninth member 24, the tenth member 25, and the eleventh member 26 are made of urethane having a hardness of 50 to 130 N (40% compression), for example. The twelfth member 27 is made of, for example, polyester hard cotton having a hardness of 200 N (40% compression) or more, and the thirteenth member 28 is made of urethane having a hardness of 50 to 130 N (40% compression), for example. Is. The upper mattress member 20 has a two-layer structure, and the hardness at the position on the mattress can be adjusted more arbitrarily and widely.

The mattress body 1 has the necessary function as a mattress on the bed by itself. Therefore, the mattress main body 1 has a function commonly required for various patients and the like, and has a minimum sleeping comfort, and even by itself, it has a function as a mattress on which the patient lies down. As described above, the patient lying on the mattress body 1 is easy to move, and the body pressure dispersibility of the buttocks is excellent. The mattress body 1 shown in FIGS. 1 and 2 has a thickness of 7 cm, for example, and can be said to be a thin type mattress. The standard type platform mattress in which the mattress body 1 and the upper mattress member 10 shown in FIG. 4 are combined is such that the thickness of the upper mattress member 10 is, for example, 9 cm, and the mattress body 1 and the upper mattress member 20 shown in FIG. In the platform mattress of the floor slip prevention type of the above combination, the thickness of the upper layer mattress member 20 is, for example, 12.5 cm. Since the upper mattress member has a different thickness as described above, it is preferable to prepare the cover 40 corresponding to each thickness. That is, the upper layer mattress member has the function to be added according to the characteristics of the bed user such as the patient, that is, the function required for each individual bed user, but the overall thickness of the mattress is Since it changes depending on the thickness, it is preferable to prepare an appropriate cover accordingly.

As shown in FIG. 5, when the upper mattress member 20 is used in combination with the mattress body 1 instead of the upper mattress member 10, the seventh member 21 having a hardness of 50 to 130 N and the hardness of 150 to 500 N are used. No. 8 member 22 is arranged in the longitudinal direction of the bed, and the eighth member 22 having a hardness of 150 to 500 N has a thickness gradually decreasing in the longitudinal direction of the bed at the inclined surface 23. The hardness is gradually decreasing as well. Therefore, in the case of the upper mattress member 20, the hardness changes in the bed longitudinal direction. That is, the bed user is supported by the seventh member 21 having a soft back, and the buttock is supported by the relatively hard eighth member 22, and the hardness of the eighth member 22 becomes lower toward the foot side. .. The upper mattress member 20 has a two-layer structure, and the soft ninth member 24, the tenth member 25, and the eleventh member 26 are arranged on the upper layer thereof, so that the feel of the bed user is comfortable. .. Moreover, since the hardness of the eighth member 22 of the buttock is relatively hard, even if the buttock that is relatively heavy in the human body sinks in the upper mattress member 20, this buttock reaches the lower mattress member 1, so-called bottom. It is possible to prevent sticking. Further, also in the case of the upper mattress member 20, since the hardness is high at the end sitting position of the bed, the end sitting position is stable, and for example, a patient undergoing rehabilitation can easily stand up in the end sitting position. However, unlike the upper mattress member 10, in the case of the upper mattress member 20, the end sitting has a two-layer structure, and the lower twelfth member 27 has a hardness of 200 N or more, but the upper thirteenth member. Since the hardness of 28 is as soft as 50 to 130 N, the tactile sensation of the bed user is comfortable.

Further, in the case of the upper layer mattress member 20, as described above, the end sitting position is stable, and the excellent body pressure dispersibility is obtained in both the supine position and the side recumbent position, and when raising the back by 30° or less. can get. The upper mattress member 20 has a two-layer structure, and has a thickness of, for example, 12.5 cm, which is 3.5 cm thicker than that of the upper mattress member 10 (for example, 9 cm in thickness) having a single-layer structure. The contact area is larger than that of the upper mattress member 10. Therefore, in the case of the mattress in which the upper mattress member 20 and the mattress body 1 are combined, the body pressure dispersibility is extremely excellent, and it is extremely effective in preventing bed sores. That is, this mattress is a floor-sore prevention type mattress having a function of excellent body pressure dispersiveness in the supine position, the lateral recumbent position, and raising the back. In addition, if the upper layer mattress member is made softer and the thickness is thicker, the contact area with the patient's body is further increased, the body pressure dispersibility becomes more excellent, and a mattress effective for prevention of pressure ulcer is assembled. You can

As described above, according to the peculiar characteristics of the bed user, the upper layer mattress member having the required function is selected and combined with one mattress main body 1 commonly used, and the mattress having the desired characteristics is selected. To get The upper-layer mattress member 10 is used for a general patient, and the upper-layer mattress member 20 is used for a patient who suffers from a significant bed slip. The mattress body 1 is commonly used by all patients. Therefore, in the present embodiment, it is possible to obtain a necessary function according to the peculiar characteristics of the patient only by exchanging the upper layer mattress member. Therefore, it is necessary to prepare a dedicated mattress having the function. In addition, equipment costs can be reduced in hospitals and nursing care facilities. In the case of home-based care, the cared person's condition changes monthly or yearly. Initially, a cared person who did not have a pressure ulcer may have a severe pressure ulcer over time, but even if the condition changes in this way, simply by replacing the upper mattress member, it is most suitable at that time. A characteristic mattress can be obtained. Therefore, the cost required for nursing care can be saved. As described above, in the present embodiment, the function specific to the patient can be added by changing only the upper mattress member to an appropriate function according to the characteristic peculiar to the bed user. Therefore, a mattress having optimum functions for a bed user can be obtained easily and at low cost, and the cost for this customization can be significantly reduced.

In the present invention, when raising the back of the Gatch bed, the bed user lying on the mattress does not shift in the longitudinal direction of the bed, and the mattress itself does not shift in the longitudinal direction of the bed. It stays in its original position without compromising sleep. Therefore, the present invention makes a great contribution to the preferred use of the Gatch bed.
