Abstract

PROBLEM TO BE SOLVED: To provide a mattress for a gatch bed that can prevent deviation of a mattress in the longitudinal direction of a gatch bed at the time of elevation of a back bottom of the bed, and that can also prevent deviation of a bed user who lies on the mattress.SOLUTION: A mattress body 1 has cushioning properties and supports the weight of a bed user. The mattress body is covered with a cover 40. In the mattress body 1, the portion corresponding to the thighs of the bed user is made of urethane material harder than the portion corresponding to the lumbar and the back of the bed user. As a result of this, the thighs are supported by the hard material and thus less likely to sink, which prevents the bed user himself or herself from being deviated toward the foot with respect to the mattress body at the time of elevation of the back bottom.SELECTED DRAWING: Figure 1

Description

  The present invention relates to a mattress for a gatch bed that does not shift with respect to the back bottom of the bed during the back raising operation of the gatch bed.

  A mattress is placed on the bottom of the gatch bed, and a bed user such as a patient lies on the mattress. And 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. It is divided into a foot bottom and the waist bottom is usually fixed, but the back bottom swings with the end on the waist bottom side as the center of rotation. When the back bottom is raised and the back raising operation is performed, the upper body of the user on the mattress is raised, and the user is easily ready for reading or watching television.

  However, in the case of such a gatch bed, when the back-up operation is performed, the user's body on the mattress is likely to be displaced in the longitudinal direction (foot direction) of the bed, and the sleeping comfort is deteriorated and the extra force There is a problem that it takes a user.

  In addition, the stress applied to the body at the time of raising the back acts in a direction in which the mattress on the back bottom also shifts in the bed longitudinal direction (foot direction). For this reason, mattress displacement is also 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 top surface of the bed (bottom) to add a slip resistance to the mattress slip. Yes.

  However, although the mattress disclosed in Patent Document 1 can prevent the mattress from sliding in the longitudinal direction of the bed, it can prevent the bed user lying on the mattress from shifting 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 such problems, and can prevent a shift of the mattress in the longitudinal direction of the bed and a shift of a bed user lying on the mattress when the back of the gatch bed is raised. The purpose is to provide a mattress.

The mattress for a gatch bed according to the present invention is
A mattress body that has cushioning properties and supports the weight of the bed user,
A cover that encloses the mattress body,
Have
The mattress main body includes a urethane material whose position corresponding to the thigh of the bed user is harder than the position corresponding to the waist and back.

In this mattress for a gatch bed,
The position corresponding to the hard urethane material on the lower surface of the cover is provided with anti-slip processing, or the anti-slip material that suppresses the sliding of the mattress at the position corresponding to the hard urethane material on the lower surface of the cover. Is preferably provided.

  The mattress main body includes a urethane base material extending in a part or all of 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 the position corresponding to the thigh can be configured to be harder than the material hardness at the position corresponding to the waist and the back.

  In the present invention, when the mattress body has a hard part, the back bottom rises and the weight of the user who tries to shift in the longitudinal direction of the mattress when the back raising operation is performed is the hard part of the mattress body. Easy to concentrate. Therefore, for example, when the mattress body is configured such that the position of the waist is soft and the position of the thigh is hard, the bed user lying on the mattress relatively sinks the waist, The part is supported by a hard material and is hard to sink. For this reason, the bed user itself is also prevented from shifting in the foot direction with respect to the mattress main body during the back raising operation. In addition, by providing a slip stopper at a position corresponding to the hard part of the mattress body on the lower surface of the cover, a load is effectively applied to the slip stopper, and a frictional force is effectively generated between the bottom and the bottom. This prevents the mattress from shifting in the longitudinal direction.

It is a perspective view which shows the mattress for gatch beds which concerns on embodiment of this invention. Similarly, it is the side view. Similarly, it is a bottom view showing a 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. Gatch beds usually have a back bottom, a waist bottom, a knee bottom, and a foot bottom in the longitudinal direction of the bed, and the waist bottom is fixed. Swings as the center. It should be noted that 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 a knee bottom and a foot bottom, In some cases, it may be fixed integrally. The back bottom supports the back of the bed user 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 includes 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 surfaces of the head side and foot portions of the first member 2. And 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 comprised from the 4th member 5 joined. 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 main body 1 has a plate shape as a whole. For example, the first member 2 is made of polyester 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%), for example. (Compression) made of urethane. Similarly, the fourth member 5 is made of urethane, but has a hardness of 150 to 500 N (40% compression) and is harder 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 main body 1 and is a base material extending in the entire area in the longitudinal direction of the bed. 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 harder than the third member 6 of the base material or the waist. As shown in FIG. 2, the auxiliary material, that is, the fourth member 5, has a wedge-shaped portion on the waist side and a flat plate shape with a uniform thickness on the foot side. . 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 main body 1 therein, and encloses the mattress main 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 be convenient for carrying the mattress. For example, the cover 40 is formed into a bag shape by joining the upper half and the lower half at the side of the cover 40, with the upper half made of knit and the lower half made of woven fabric. ing. A product logo or the like can be displayed on the upper surface of the cover 40 by silk printing.

  The anti-slip portion 43 is formed on the lower surface of the cover 40 by anti-slip processing on the portion corresponding to the hard fourth member 5, that is, the portion corresponding to the thigh of the bed user lying on the mattress. Is provided. The anti-slip processing of the anti-slip portion 43 can be performed by depositing a rubber material in a planar shape, but this means can take other various means. The anti-slip part 43 preferably 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 500N, and the third member 6 supporting the waist is a soft material of 50 to 130N. Therefore, the bed user's waist is relatively easy to sink with the third member 6, and the auxiliary material (fourth member 5) for supporting the thigh is made of a hard material of 150 to 500N. Therefore, the thigh of the bed user is supported by the auxiliary material (fourth member 5) and does not sink relatively. For this reason, a user's buttocks (waist) is locked to the auxiliary material (fourth member 5) and does not shift in the bed longitudinal direction (foot direction). In addition, since the cover 40 is provided with the anti-slip portion 43, the mattress itself is also displaced with the knee bottom (leg bottom) due to a large frictional force, causing a shift in the bed longitudinal direction. There is no. Further, when the bed user sits on the mattress, the buttock receives a reaction force from the auxiliary material (fourth member 5), and it becomes easy to take a sitting posture with the pelvis standing.

  The mattress body 1 has a first member 2 formed of polyester cotton having a hardness of 200 N or more, and the first member 2 is disposed in the entire area in the longitudinal direction of the bed. Since the third member 6 made of soft urethane having a hardness of 50 to 130 N is disposed on the first member 2, the back and legs 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 characteristics that the waist part is easily depressed and the back part and the leg part are difficult to sink.

  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 body 1. The upper mattress member 10 has a planar shape (width and length) similar to that of the mattress main body 1, and includes a fifth member 11 at the center and sixth members 13 at both ends in the width direction. For example, the fifth member 11 is 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 the fifth member 11 at the center is harder. 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 main body 1 are accommodated in the cover 40 in an overlaid state. For example, when the upper mattress 10 has a surface fastener bonded to a part of its lower surface and a material having a function of a surface fastener is used as the material of the upper surface of the mattress main body 1, the upper mattress member 10 and the mattress main body 1 Can be separably locked and fixed to each other with the hook-and-loop fasteners. As what has the function of the surface fastener of this mattress main body 1, the 3rd member 6 of the mattress main body 1 can be formed with a filmless urethane, for example. This filmless urethane refers to a urethane that leaves only a skeleton by skipping a small film in the structure of a normal urethane foam in order to improve the water flow during washing and the air permeability during drying. Thereby, the upper surface of the third member 6 has a function as a surface fastener, and the upper layer mattress member 10 and the mattress main body 1 are mutually locked with the surface fastener on the lower surface of the upper layer mattress member 10. Can do.

  In the case of this mattress, the same effects as the mattress shown in FIG. That is, the user's buttocks (waist) is locked by the auxiliary material (fourth member 5) and does not shift in the bed longitudinal direction (foot direction). In addition, since the cover 40 is provided with the anti-slip portion 43, the mattress itself is also displaced with the knee bottom (leg bottom) due to a large frictional force, causing a shift in the bed longitudinal direction. There is no. Further, when the bed user sits on the mattress, the buttock receives a reaction force from the auxiliary material (fourth member 5), and it becomes easy to take a sitting posture with the pelvis standing.

  However, in the mattress main body, the upper mattress member 10 can further adjust the hardness of the mattress and can improve the sleeping comfort. That is, in the case of this mattress, the sixth member 13 at the end portion of the upper mattress member 10 when the patient sits on the end portion in the width direction of the bed and takes an end-sitting posture to get out of the bed. The patient's hardness is higher than that of the central part, so that the patient can easily get out of bed. The upper layer mattress member 10 disposed on the mattress main body 1 is occupied by the fifth member 11 made of a soft urethane having a hardness of 50 to 130 N over the entire region in the longitudinal direction of the upper layer mattress member 10. 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 superimposed 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.

  Thus, when the bed user (patient) lies down on the bed, the waist (buttock) has the first member 2 having a hardness of 200 N or more in the lowermost layer, and the hardness is further on it. Since the fifth member 11 having 50 to 130N and the third member 6 having a hardness of 50 to 130N are disposed on the laminated body, the fifth member 11 is substantially supported by urethane having a hardness of 50 to 130N. The patient's back is composed of a first member 2 made of hard polyester hard cotton having a hardness of 200 N (40% compression) or more in the lowermost layer of the second member 3 having a hardness of 50 to 130 N, and a hardness of 50. Since it is located on what the laminated body with the 5th member 11 of thru | or 130N is arrange | positioned, the influence of the hard 1st member 2 is strong, and it will be supported by the member harder than a waist | hip | lumbar part (buttock part). The leg is supported by the same hardness as the back. Further, the patient's thigh is formed on the laminated body of the fourth member 5 having a hardness of 150 to 500N, the first member 2 made of polyester hard cotton, and the fifth member 11 having a hardness of 50 to 130N. Therefore, it is supported by a member harder than the back and legs as well as the waist. In this way, the buttocks are supported by the softest member (hardness 50 to 130N), the back and legs are supported by members harder than the buttocks, and the thigh is supported by members harder than the back and legs. Will be. For this reason, this mattress is easy for the patient to turn over, and the patient's buttocks are supported by a member having a hardness of 50 to 130 N, so that the body pressure dispersibility is excellent, and the sleeping comfort and body pressure dispersibility are excellent. Both have an excellent balance. Moreover, as described above, the patient can easily get out of bed. Therefore, the combination of the mattress main body 1 and the upper mattress member 10 is a standard type mattress that has excellent sleeping comfort and body pressure dispersibility, and has a function of stabilizing the end sitting position.

  FIG. 5 shows another upper layer mattress member 20. The upper layer mattress member 20 includes two seventh members 21 and eighth members 22 juxtaposed in the bed longitudinal direction at the center in the bed width direction. In the eighth member 22, a portion having a uniform thickness and a portion which is an inclined surface 23 whose thickness gradually decreases and whose upper surface is inclined are continuous in the longitudinal direction of the bed. The ninth member 24 and the tenth member 25 are disposed on the flat surfaces of the seventh member 21 and the eighth member 22, and the eleventh member 26 is disposed on the inclined surface 23 of the eighth member 22. Has 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 in the entire length in the bed longitudinal direction is disposed. On the twelfth member 27, the bed longitudinal A thirteenth member 28 extending in the direction is disposed. The seventh member 21 to the thirteenth member 28 are joined to each other and integrally formed. The seventh member 21 is made of, 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 urethane having a hardness of 50 to 130 N (40% compression), for example. The twelfth member 27 is made of polyester 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. 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.

  Note that the mattress body 1 alone has a function necessary as a mattress on a bed. Therefore, the mattress body 1 has a function that is commonly required for various patients and the like, has a minimum sleeping comfort, and 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 has excellent body pressure dispersibility in the buttocks. 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 mattress. The standard type mattress of the mattress body 1 and the upper mattress member 10 shown in FIG. 4 has a thickness of, for example, 9 cm, and the mattress body 1 and the upper mattress member 20 shown in FIG. In this combination, the floor mattress prevention type platform mattress has a thickness of the upper mattress member 20 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 cover 40 corresponding to each thickness. That is, the upper layer mattress member has a function to be added according to the characteristics of the bed user such as a patient, that is, a function necessary for each bed user, but the total thickness of the mattress is determined by the upper layer mattress member. Since it varies 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 main body 1 instead of the upper mattress member 10, the seventh member 21 having a hardness of 50 to 130N and the hardness of 150 to 500N are used. The eighth member 22 is disposed in the longitudinal direction of the bed, and the thickness of the eighth member 22 having a hardness of 150 to 500 N gradually decreases in the longitudinal direction of the bed at the inclined surface 23 portion. The hardness is gradually decreasing as well. Therefore, in the case of the upper layer 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 portion is soft, the heel portion is supported by the relatively hard eighth member 22, and the hardness of the eighth member 22 decreases as the foot side is approached. . The upper layer mattress member 20 has a two-layer structure, and the soft ninth member 24, the tenth member 25, and the eleventh member 26 are disposed on the upper layer, so that the bed user feels comfortable. . Further, since the hardness of the eighth member 22 of the buttocks is relatively hard, even when a relatively heavy buttocks sinks in the upper mattress member 20 in the human body, the so-called bottom where the buttocks reach the lower mattress member 1 It is prevented that sticking occurs. Also, in the case of the upper layer mattress member 20, since the hardness is high at the position of the end sitting position of the bed, the end sitting position becomes stable, and for example, a patient during rehabilitation can easily stand up in the end sitting position. However, unlike the upper-layer mattress member 10, the upper-layer mattress member 20 has a two-layer end position, 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 feeling of the bed user is comfortable.

  Further, in the case of the upper mattress member 20, as described above, the end sitting position is stable, and excellent body pressure dispersibility is obtained in both the supine position and the lateral position, and also when the back is raised 30 degrees or less. can get. The upper mattress member 20 has a two-layer structure, for example, a thickness of 12.5 cm, and is 3.5 cm thicker than a single-layer upper mattress member 10 (for example, a thickness of 9 cm). 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 main body 1 are combined, the body pressure dispersibility is extremely excellent, and it is extremely effective for preventing bed slip. That is, this mattress is a bed slip prevention type mattress having functions of excellent body pressure dispersibility at the supine position, the lateral position and the back-up position. In addition, if the upper mattress member is softer and thicker, the contact area with the patient's body increases, the body pressure dispersibility becomes better, and a mattress that is effective in preventing pressure ulcers is assembled. Can do.

  As described above, an upper layer mattress member having a necessary function is selected according to the specific characteristics of the bed user, and the mattress having desired characteristics is combined with a single mattress body 1 that is used in common. Get. In the case of a general patient, the upper layer mattress member 10 is used, and in the case of a patient with significant bed slip, the upper layer mattress member 20 is used. The mattress body 1 is used in common for all patients. For this reason, in the present embodiment, a necessary function according to the patient's unique characteristics can be obtained simply by replacing the upper mattress member. Therefore, it is necessary to prepare a dedicated mattress having the function. In addition, equipment costs can be reduced in hospitals and care facilities. Even in the case of home care, the care recipient changes in units of months or years. Initially, care recipients who did not have pressure ulcers may experience severe pressure ulcers over the years, but even if the condition changes in this way, it is best to replace the upper mattress member. A characteristic mattress can be obtained. Therefore, the cost required for care can be saved. As described above, in the present embodiment, by changing only the upper layer mattress member to a proper function necessary for the patient, a function corresponding to the characteristics unique to the bed user can be added. Therefore, a mattress having an optimal function for the bed user can be obtained easily and at low cost, and the cost for customization can be significantly reduced.

  In the present invention, 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 at the time of raising the back of the gatch bed. It remains in its original position and does not impair sleep. Thus, the present invention makes a great contribution to the preferred use of a gatch bed.
