Description

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

  A mattress is placed on the bottom of the gatch bed, and a bed user such as a patient lies on the mattress. In the gatch bed, the bottom corresponds to the back bottom corresponding to the back part of the user, the waist bottom corresponding to the waist part, the knee bottom corresponding to the thigh part, and the foot part. Normally, the waist bottom is fixed, but the back bottom swings around the end on the waist bottom side as a center of rotation. When the back bottom is raised and the back is lifted, the upper body of the user on the mattress is raised, and the user is in a posture that makes it easy to read or watch television.

  However, in the case of such a gatch bed, when the backrest operation is performed, the user's body on the mattress is likely to be displaced in the longitudinal direction (foot direction) of the bed, so that it is difficult to sleep and extra force is applied. However, there is a problem that it affects the user.

  In addition, when the back is raised, the stress applied to the body also acts in a direction in which the mattress on the back bottom is displaced in the bed longitudinal direction (foot step direction). For this reason, the displacement of the mattress also poses a problem.

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

  However, the mattress disclosed in Patent Literature 1 can prevent the mattress from sliding in the bed longitudinal direction, but can prevent the bed user lying on the bed mattress from shifting in the bed longitudinal direction. There is a problem that it is not.

  The present invention has been made in view of such a problem, and a gatch bed capable of preventing a mattress from shifting in the longitudinal direction of the bed when the back of the gatch bed is raised and a bed user lying on the mattress from shifting. It is intended to provide a mattress for use.

The mattress for a gatch bed according to the present invention,
A mattress body having cushioning properties and supporting the weight of the bed user,
A cover for enclosing the mattress body,
Has,
The mattress main body is characterized in that a position corresponding to the thigh of the bed user includes a urethane material which is harder than positions corresponding to the waist and the back.

In this mattress for gatch bed,
A position corresponding to the hard urethane material on the lower surface of the cover is subjected to a non-slip process, or a position corresponding to the hard urethane material on the lower surface of the cover, a slip stopper for suppressing a mattress from sliding. Is preferably provided.

  Further, the mattress body has a urethane base material extending in a part or the entire area in the longitudinal direction of the bed, and a urethane auxiliary material disposed at a position corresponding to the thigh, and the auxiliary material The material hardness at a position corresponding to the thigh may be configured to be harder than the material hardness at positions corresponding to the waist and the back.

  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 intends to shift in the mattress longitudinal direction is in the hard portion of the mattress body. Easy to concentrate. Therefore, if the mattress body is configured such that, for example, the position of the waist is soft and the position of the thigh is hard, the bed user lying on the mattress, although its waist relatively sinks, The part is hard to sink because it is supported by a hard material. For this reason, the bed user is also prevented from being displaced in the footstep direction with respect to the mattress body during the back-up operation. In addition, by providing a non-slip at a position corresponding to the hard portion of the mattress body on the lower surface of the cover, a load is effectively applied to the non-slip, and a frictional force is effectively applied to the bottom below the non-slip. This prevents the mattress from shifting in its longitudinal direction.

It is a perspective view showing the mattress for the gatch bed concerning the embodiment of the present invention. FIG. Similarly, it is a bottom view showing the lower 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. Gatch beds usually have a back bottom, a waist bottom, a knee bottom and a foot bottom arranged in the longitudinal direction of the bed, the waist bottom is fixed, and the back bottom swings at the waist bottom end with respect to the waist bottom. Swing as center. In addition, the knee bottom and the foot bottom constitute a leg bottom, and can often swing separately and independently, but the leg bottom is not divided into the knee bottom and the foot bottom. In some cases, they are integrally fixed. 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 and 4 joined to the lower surface of the head and foot portions of the first member 2. And a third member 6 joined to an upper surface of a waist portion of the first member 2 and a lower surface of a portion between the third member 6 and the foot-side second member 4 in the first member 2 in plan view. And the fourth member 5 joined. The upper surfaces of the first member 2 and the third member 6 are substantially flush, and the lower surfaces of the second members 3, 4, and the fourth member 5 and the lower surface of the waist portion of the first member 2 are substantially flush. is there. Therefore, the mattress main body 1 has a plate shape as a whole. The first member 2 is made of, for example, a polyester hard cotton having a hardness of 200N (40% compression) or more, and the second members 3, 4, and the third member 6 have a hardness of, for example, 50 to 130N (40%). (Compression) urethane. The fourth member 5 is also 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 is a basic structural material of the mattress main body 1 and is a base material extending over the entire area in the longitudinal direction of the bed. Further, the third member 6 corresponding to the waist is formed 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 base material or a material harder than the third member 6 of the waist. As shown in FIG. 2, the cross-sectional shape of the auxiliary member, that is, the fourth member 5 is such that the waist portion has a wedge shape and the foot portion has a flat plate shape 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 the present embodiment. As shown in FIG. 3, the cover 40 has a bag shape, houses the mattress body 1 therein, and encloses the mattress body 1. Fasteners 41 are provided on the side of the end of the cover 40 in the longitudinal direction of the bed and a part of the sides on both sides thereof, and the mattress body 1 is housed inside by opening and closing the fasteners 41. Two pairs of handles 42 are provided on both sides of the cover 40 so as to provide convenience for carrying the mattress. For example, the cover 40 has an upper half made of knit and a lower half made of fabric. The upper half and the lower half are joined at the side of the cover 40 to form a bag. 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 performing a non-slip process on a portion corresponding to the hard fourth member 5, that is, a portion corresponding to the thigh of a bed user lying on the mattress. Is provided. The anti-slipping processing of the anti-slipping portion 43 can be performed by applying a rubber material in a planar shape, but this means can take various other means. It is preferable that the non-slip portion 43 has a length of 100 mm or more in the longitudinal direction of the bed and a width of 150 mm or more.

  In the mattress of the present embodiment configured as described above, the auxiliary member (fourth member 5) is formed of a hard material of 150 to 500N, and the third member 6 for supporting the waist is formed of a soft material of 50 to 130N. Therefore, the waist of the bed user is relatively easily sinked by the third member 6, and the auxiliary material (the fourth member 5) for supporting the thigh is formed of a hard material of 150 to 500N. Therefore, the thigh of the bed user is supported by the auxiliary member (fourth member 5) and does not sink relatively. For this reason, the buttocks (waist) of the user are locked by the auxiliary member (fourth member 5) and do not shift in the bed longitudinal direction (foot direction). Also, since the cover 40 is provided with the non-slip portion 43, the mattress itself may be displaced in the longitudinal direction of the bed due to a large frictional force acting between the mattress itself and the knee bottom (leg bottom). There is no. Further, when the bed user sits on the mattress, the buttocks receive a reaction force from the auxiliary material (the fourth member 5), and thus the pelvis can easily take a sitting posture in which the pelvis stands.

  In the mattress body 1, the first member 2 is formed of a polyester hard cotton having a hardness of 200N or more, and the first member 2 is disposed in the entire area in the bed longitudinal direction. In the waist portion of the user, the third member 6 made of soft urethane having a hardness of 50 to 130 N is disposed on the first member 2, so that the back and the leg of the bed user are supported by a hard material. The waist is supported by a soft material. For this reason, the lower layer mattress member 1 of the present embodiment has such characteristics that the waist is easily sunk, and the back and the legs are hard to sunk.

  FIG. 4 is a view showing a modification of the mattress in which the mattress main body 1 and the upper mattress member 10 are laminated. As shown in FIG. 4, the upper mattress member 10 is detachably stacked on the mattress main body 1. The upper mattress member 10 has the same planar shape (width and length) as the mattress main body 1, and is composed of a fifth member 11 at the center 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 made of, for example, urethane, but has a hardness of 150 to 500 N (40% compression). ), And is harder than the fifth member 11 at the center. The surface of the fifth member 11 is subjected to a roughening treatment 12. In this case, the upper layer mattress member 10 and the mattress main body 1 are stored in the cover 40 in a state of being overlapped. For example, when the upper mattress 10 has a hook-and-loop fastener joined to a part of the lower surface thereof and a material having a hook-and-loop fastener function is used as a material of the upper surface of the mattress main body 1, the upper mattress member 10 and the mattress main body 1 are connected to each other. Can be separably locked between the hook-and-loop fasteners and fixed to each other. The third member 6 of the mattress main body 1 can be formed of, for example, urethane without a film so as to have a function of a hook-and-loop fastener of the mattress main body 1. This urethane without a membrane refers to urethane that leaves only a skeleton by skipping a small membrane in a normal urethane foam structure in order to improve water flow during washing and air permeability during drying. Thereby, the upper surface of the third member 6 has a function as a hook-and-loop fastener, and the upper mattress member 10 and the mattress main body 1 are mutually locked between the third member 6 and the hook-and-loop fastener on the lower surface of the upper mattress member 10. Can be.

  This mattress also has the same effect as the mattress shown in FIG. That is, the buttocks (waist) of the user are locked by the auxiliary member (fourth member 5) and do not shift in the longitudinal direction of the bed (foot direction). Also, since the cover 40 is provided with the non-slip portion 43, the mattress itself may be displaced in the longitudinal direction of the bed due to a large frictional force acting between the mattress itself and the knee bottom (leg bottom). There is no. Further, when the bed user sits on the mattress, the buttocks receive a reaction force from the auxiliary material (the fourth member 5), and thus the pelvis can easily take a sitting posture in which the pelvis stands.

  However, in this mattress main body, the hardness of the mattress can be variously adjusted by the upper layer mattress member 10, so that there is an effect that the sleeping comfort can be improved. That is, in the case of this mattress, when the patient sits at the end in the width direction of the bed and takes the posture of the end sitting position in which the patient tries to get out of the bed, the sixth member 13 at the end of the upper mattress member 10 is used. The patient is more likely to leave the bed because the hardness of the patient is higher than in the center. The upper layer mattress member 10 arranged on the mattress body 1 has a width central portion occupied by a soft urethane fifth member 11 having a hardness of 50 to 130 N over the entire region in the longitudinal direction. Therefore, the relative rigidity of the support by the mattress body 1 does not change. That is, as a mattress in which the upper layer mattress member 10 is overlaid on the mattress body 1, the back and the leg of the bed user are supported by a relatively hard material, and the waist is supported by a relatively soft material.

  As described above, when the bed user (patient) lies on the bed, the waist (buttock) is provided with the first member 2 having a hardness of 200N or more in the lowermost layer, and the hardness is placed thereon. 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 disposed on the stacked body, the support is substantially supported by urethane having a hardness of 50 to 130N. The lower part of the patient's back has a second member 3 having a hardness of 50 to 130 N, a first member 2 made of hard polyester cotton having a hardness of 200 N (40% compression) or more, and a hardness of 50 N. Since it is located on the portion where the laminated body with the fifth member 11 of from 1 to 130N is arranged, the effect of the hard first member 2 is strong, and the member is supported by a member harder than the waist (buttock). The legs are supported on a portion of the same hardness as the back. Further, the thigh of the patient is placed on a laminate of a fourth member 5 having a hardness of 150 to 500N, a first member 2 made of polyester hard cotton, and a fifth member 11 having a hardness of 50 to 130N. Is supported by members that are harder than the waist, the back and the legs. Thus, the buttocks are supported by the softest member (hardness 50 to 130N), the back and legs are supported by members that are harder than the members of the buttocks, and the thighs are supported by members that are harder than the members of the back and legs. Will be done. For this reason, this mattress is easy for the patient to turn over, and since the buttocks of the patient are supported by a member having a hardness of 50 to 130N, the body pressure dispersibility is excellent, and the comfort and the body pressure dispersibility are improved. Both will have an excellent balance. Moreover, as described above, the patient easily gets out of bed. Therefore, the combination of the mattress main body 1 and the upper layer mattress member 10 is a standard type mattress having a function of excelling in sleeping comfort and body pressure dispersibility and stabilizing an end sitting position.

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

  The mattress body 1 alone has a function necessary as a mattress on a bed. Therefore, the mattress main body 1 has functions required in common for various patients and the like, has a minimum sleeping comfort, and has a function as a mattress on which the patient lies alone. 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, for example, 7 cm, and can be said to be a thin type mattress. The standard type platform mattress of the combination of the mattress body 1 and the upper mattress member 10 shown in FIG. 4 has a thickness of the upper mattress member 10 of, for example, 9 cm, and the mattress body 1 and the upper mattress member 20 shown in FIG. In the platform mattress of the bedsore prevention type of the combination of the above, the thickness of the upper layer mattress member 20 is, for example, 12.5 cm. As described above, since the thickness of the upper mattress member is different, it is preferable to prepare the cover 40 corresponding to each thickness. That is, the function to be added according to the characteristics of the bed user such as a patient, that is, the function necessary for each bed user, is provided by the upper mattress member, but the overall mattress thickness is determined by the thickness of the upper mattress member. Since the thickness varies depending on the thickness, it is preferable to prepare an appropriate cover according to the thickness.

  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 seventh member 21 having a hardness of 150 to 500 N Are arranged in the bed longitudinal direction, and the thickness of the eighth member 22 having a hardness of 150 to 500 N gradually decreases in the bed longitudinal direction at the inclined surface 23, The hardness is also gradually decreasing. 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 whose back is soft, and the buttocks are supported by the eighth member 22 which is relatively hard, and the hardness of the eighth member 22 becomes lower toward the foot. . The upper layer mattress member 20 has a two-layer structure, and the ninth member 24, the tenth member 25, and the eleventh member 26, which are soft, are disposed on the upper layer, so that the bed user can feel comfortable. . Also, since the hardness of the eighth member 22 of the buttocks is relatively hard, so-called bottom where the buttocks reach the lower mattress member 1 even when the relatively heavy buttocks sink in the upper mattress member 20 in the human body. Sticking is prevented from occurring. Also in the case of the upper mattress member 20, since the hardness is high at the position of the end sitting position of the bed, the end sitting position is stable, and for example, a patient during rehabilitation can easily stand up at the end sitting position. However, unlike the upper mattress member 10, in the case of the upper mattress member 20, the end sitting position has a two-layer structure, and the lower twelfth member 27 has a hardness of 200 N or more, but the upper thirteenth member. 28 is soft, having a hardness of 50 to 130 N, so that the bed user can feel comfortable.

  Further, in the case of the upper mattress member 20, as described above, the end sitting position is stable, and in both the supine position and the lateral position, and even when the back is raised by 30 ° or less, excellent body pressure dispersibility is obtained. can get. The upper layer mattress member 20 has a two-layer structure, for example, a thickness of 12.5 cm, and is 3.5 cm thicker than the upper layer mattress member 10 (for example, the thickness is 9 cm) of a single-layer structure. The contact area is larger than that of the upper mattress member 10. Therefore, in the case of a mattress in which the upper mattress member 20 and the mattress main body 1 are combined, the body pressure dispersibility is extremely excellent, and it is extremely effective in preventing bedsores. In other words, this mattress is a mattress of a bedsore prevention type having a function of excellent body pressure dispersibility in the supine position, the lateral position, and when raising the back. In addition, if the upper layer mattress member is softer and thicker, the contact area with the patient's body increases, the body pressure dispersibility becomes more excellent, and an effective mattress for pressure ulcer prevention is assembled. Can be.

  As described above, an upper layer mattress member having a necessary function is selected according to a characteristic peculiar to a bed user, and this member is combined with one mattress body 1 commonly used to form a mattress member having desired characteristics. Get. The upper mattress member 10 is used for a general patient, and the upper mattress member 20 is used for a patient with severe bedsores. The mattress body 1 is commonly used by all patients. For this reason, in this embodiment, since the required function according to the characteristic of the patient can be obtained only by replacing the upper mattress member, it is necessary to prepare a dedicated mattress having the function. However, in hospitals and nursing homes, equipment costs can be reduced. In the case of home care, the condition of the cared person changes on a monthly or yearly basis. At first, caregivers who did not have pressure ulcers may have severe pressure ulcers over the years, but if the condition changes in this way, simply replace the upper mattress member, and A mattress with characteristics can be obtained. Therefore, the cost required for nursing care can be saved. As described above, in the present embodiment, a function corresponding to a characteristic peculiar to a bed user can be added by changing a specific function necessary for a patient to an appropriate one only in the upper mattress member. Therefore, it is possible to easily and inexpensively obtain a mattress having an optimal function for a bed user, and it is possible to significantly reduce the cost for this customization.

  In the present invention, the bed user lying on the mattress does not shift in the longitudinal direction of the bed when the gatch bed is raised, and the mattress itself does not shift in the longitudinal direction of the bed. It stays in its original position and doesn't hurt your sleep. Thus, the present invention makes a significant contribution to the preferred use of a gatch bed.
