Description

  The present invention relates to a mattress used for a gatch bed or the like, which can be customized to have appropriate characteristics according to the condition of a patient lying on the mattress, and a method of using the same.

  A mattress is placed on a frame of a bed such as a gatch bed and a fixed bed, and a bed user such as a patient lies on the mattress. In this case, the mattress emphasizes dispersibility of body pressure, emphasizes ease of movement such as turning over, emphasizes comfort (sleeping comfort), resists the user's body, emphasizes prevention of pressure ulcers Various products are prepared according to the functions required, such as those that are easily bent when the back up and back down operations of the Gatch bed are performed. The bed user selects and uses an appropriate product according to the function he needs.

  However, as described above, mattresses are different products depending on their functions, and it is necessary to prepare various mattress products having different functions in facilities that accommodate patients such as hospitals and nursing care facilities. For this reason, in order to purchase such a mattress product, it is necessary to bear a large amount of equipment cost in facilities such as hospitals and nursing care facilities, and such a cost can be borne in facilities with insufficient funds. However, there is a problem that a necessary and sufficient mattress cannot be provided for treatment and care.

  In addition, whenever a mattress product having a new function is released, it is necessary to purchase and install a new mattress, and in this respect as well, an increase in equipment cost is a problem.

  Furthermore, depending on the condition of the patient, the necessary functions vary from day to day or from time to time, but in the case of home care, it is necessary to prepare various mattresses with different functions, such as cost, storage space, etc. Because of the problem, it can not be reached at all.

  As a conventionally proposed mattress for a bed, Patent Document 1 discloses that a mattress piece in which a mattress material is encased by a side ground has a two-layer structure of an upper layer and a lower layer. A plurality of pairs arranged in the longitudinal direction and sliding an upper mattress piece to prevent body sinking and pressure ulcers are disclosed.

  Further, Patent Document 2 discloses a bedding in which a mattress is stacked and placed on a mattress, the hardness of the mattress can be adjusted according to each body member of the user, and transportation and storage are facilitated. .

  Furthermore, in Patent Document 3, an upper mat is stacked on a lower undermat, and the upper mat is divided into three main parts, and an edge mat arranged on the left and right sides of the main part and divided into three parts. An assembly-type mattress composed of the above-mentioned is disclosed, and the assembly-type that reduces the sense of incongruity caused by a step generated between adjacent mat members by preventing the boundaries between the divided parts of the main body portion and the edge mat from matching each other. A mattress is disclosed.

  Furthermore, in Patent Document 4, each mattress component divided into three in the bed longitudinal direction is obtained by enclosing a lower mattress piece and an upper mattress piece with a mattress cover, and is applied to a gatch bed. In addition, there is disclosed a split mattress in which three divided mattress structures are curved into a shape that conforms to the shape of the bed so that the user's body on the mattress does not slip and pressure sores are prevented. .

  Furthermore, Patent Document 5 discloses an assembly type mattress in which a plurality of cushion members are connected by fasteners, and each cushion member can be selected in a divided state. .

  Furthermore, in Patent Document 6, as a mattress for a gatch-type bed, a first layered member and a second layered member are laminated with a sliding sheet interposed therebetween, and these interior bodies are arranged. Has been disclosed that is encapsulated and integrated with an exterior body. This mattress is easy to bend when the back-up operation is performed in a gatch bed, while the first layered member and the second layered member slide relative to each other by the slippery sheet, and the exterior body expands and contracts. .

  However, the mattresses disclosed in Patent Documents 1 to 6 cannot easily customize individually necessary functions for a bed user such as a patient. Therefore, the bed user needs to replace the entire mattress in order to obtain the necessary functions individually, and there is a problem that the equipment cost is high as described above.

  The present invention has been made in view of such problems, and can provide functions necessary specifically for a bed user such as a patient at a low cost, and an optimal mattress according to each bed user. It is an object to provide a platform mattress that can be easily customized and a method of using the same.

The platform mattress according to the present invention is:
A lower mattress member having a function required as a mattress on a bed;
With the function to be added or increased to the lower layer mattress member according to the characteristics of the bed user, an upper layer mattress member with an integrated structure,
In a state where the upper mattress member is detachably overlaid on the lower mattress member, a bag-like cover encapsulating them,
Have
The upper mattress member has a central region divided into a plurality of portions in the bed longitudinal direction corresponding to the back, buttocks and feet of the bed user, and end sitting regions on both sides in the bed width direction. you is,
The central region of the upper layer mattress member is composed of a central upper layer portion and a central lower layer portion,
The hardness of the central lower layer corresponding to the buttocks and feet in the central region is made of a material harder than the hardness of the central lower layer and the central upper layer corresponding to the back,
The center lower layer part corresponding to the foot part of the upper layer mattress member is inclined so that its surface descends toward the foot side tip part of the bed, and the hardness decreases toward the foot side tip part. ,
The end sitting region is harder than a portion corresponding to the back portion of the central region, and has a function that a user can easily stand up .

In this platform mattress, for example,
The central lower layer portion corresponding to the central upper layer portion and the back portion is made of a material having a hardness of 50 to 130 N (40% compression), and the central lower layer portion corresponding to the heel portion and the foot portion has a hardness. Made from 150-500N (40% compression) material.

  Further, the upper layer mattress member has a function required according to the specific characteristics of the bed user, and the lower layer mattress member can be configured to be commonly used for all patients. .

In a further, the use of the platform of the mattress according to the present invention,
When the bed user is changed or when the state of the bed user changes, an upper layer mattress member having an appropriate function is selected according to the current state of the bed user, and the lower layer mattress member The upper layer mattress member having an appropriate function is overlapped with the cover and used as a mattress.

  In the present invention, the lower mattress member has a function necessary as a mattress on a bed, and has a necessary function in common for bed users such as various patients, and has a minimum sleeping comfort. However, it functions as a mattress on which the patient lies. Further, a function to be added or increased to the lower mattress member according to the characteristics of the bed user such as a patient, that is, a function that is inherently necessary for each bed user and is insufficient for the lower mattress member. Has an upper mattress member. Then, the lower mattress member and the upper mattress member are stored in the cover and integrated to be used as a mattress. This will result in different patients using the bed, and if the specific function required for that patient is different from the previous patient, or if the patient's condition has changed over time, the required function has changed. In this case, by changing only the upper mattress member to an appropriate one, a function corresponding to the characteristics specific to the bed user can be added or selected. Therefore, a mattress having an optimal function for the bed user can be obtained easily and at low cost, and the cost for this customization can be significantly reduced.

(A), (b), (c) is a perspective view which respectively shows the platform mattress which concerns on embodiment of this invention. (A), (b), (c) is a side view which respectively shows the platform mattress which concerns on embodiment of this invention. 1 is an external view of a platform mattress according to an embodiment of the present invention.

  Hereinafter, a platform mattress according to an embodiment of the present invention and a method of using the same will be described. FIG. 1A and FIG. 2A are views showing a lower mattress member 1. The lower mattress member 1 includes a first member 2 having a width and a length corresponding to the entire surface of the bed, and a second member 3 joined to the lower surface of the head side and foot portions of the first member 2. 4, the third member 6 joined to the upper surface of the waist portion of the first member 2, and the lower surface of the first member 2 between the third member 6 and the foot side second member 4 in plan view. And a fourth member 5 joined to each other. 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 lower layer mattress member 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 is a basic structural material of the lower mattress member 1. The third member 6 corresponding to the waist is made of a slightly soft material, and the fourth member 5 corresponding to the thigh is made of a slightly hard material.

  As shown in FIG. 1B and FIG. 2B, the upper layer mattress member 10 is detachably stacked on the lower layer mattress member 1. The 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 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. For example, when the upper layer mattress 10 has a surface fastener bonded to a part of its lower surface and a material having a surface fastener function is used as the upper surface material of the lower layer mattress member 1, the upper layer mattress member 10 and the lower layer mattress member are used. 1 can be separably locked and fixed to each other with the surface fasteners. As what has the function of the surface fastener of this lower layer mattress member 1, the 3rd member 6 of the lower layer mattress member 1 can be formed, for example with urethane without a film | membrane. 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 functions as a surface fastener, and the upper layer mattress member 10 and the lower layer mattress member 1 are mutually locked with the surface fastener on the lower surface of the upper layer mattress member 10. be able to.

  FIG. 3 is a perspective view showing the cover 40 of the present embodiment. As shown in FIG. 3, the cover 40 has a bag shape, accommodates a laminated body of the lower layer mattress member 1 and the upper layer mattress member 10, and encloses the lower layer mattress member 1 and the upper layer mattress member 10. To do. Fasteners 41 are provided on the sides of the end of the cover 40 in the longitudinal direction of the bed and the sides on both sides that follow. By opening and closing the fasteners 41, the lower mattress member 1 and the upper mattress member 10 are Store inside. 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 upper portion 40 a of the cover 40 is made of knit, and the lower portion 40 b is made of woven fabric and joined at the side portion of the cover 40. A product logo or the like can be displayed on the upper surface of the upper portion 40a by silk printing.

  FIG. 1C and FIG. 2C show 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, 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, and the eighth member 22 is, for example, hardness Is 150 to 500 N (40% compression) urethane. 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 lower layer mattress member 1 alone has a necessary function as a mattress on a bed. Therefore, the lower-layer mattress member 1 has functions that are 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 lower layer mattress member 1 is easy to move and has excellent body pressure dispersibility in the buttocks. The lower mattress member 1 shown in FIG. 1A has a thickness of 7 cm, for example, and can be said to be a thin mattress. The standard type platform mattress of the combination of the lower mattress member 1 and the upper mattress member 10 shown in FIG. 1B has a thickness of, for example, 9 cm, and the lower mattress member 1 and the upper mattress shown in FIG. The bed mattress prevention type mattress combined with the member 20 has 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 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.

  In the present embodiment configured as described above, as shown in FIGS. 1B and 2B, the upper mattress member 10 is overlaid on the lower mattress member 1, and the fastener of the cover 40 shown in FIG. 41 is opened, and the laminated body of the upper mattress member 10 and the lower mattress member 1 is accommodated in the cover 40. Then, after closing the fastener 41 and storing the upper mattress member 10 and the lower mattress member 1 together, the mattress is transported onto the bed frame using the handle 42 for use. In this mattress, the lower mattress member 1 has a function that is necessary for all people as a mattress, or has a minimum necessary function as a bedding. Even if only this lower mattress member 1 is used, Can be used. For the individual bed user, a function that is insufficient only by the lower layer mattress member 1, that is, a function that is inherently necessary for each individual bed user but cannot be obtained only by the lower layer mattress member 1, is an upper layer mattress. The member 10 takes charge.

  In the lower mattress member 1 shown in FIGS. 1 (a) and 2 (a), the first member 2 is formed of polyester hard cotton having a hardness of 200 N or more, and this first member 2 is the entire area in the bed longitudinal direction. However, the portion of the user's lower back lying on the bed has the third member 6 made of a soft urethane having a hardness of 50 to 130 N on the first member 2. The user's back and legs are supported by a hard material, and 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.

  Further, in the upper mattress member 10, when the patient sits at the end in the width direction of the bed and takes the posture of the end sitting position to get out of the bed, the sixth member at the end of the upper mattress member 10. Since the hardness of 13 is higher than that of the central portion, the patient can easily get out of bed. The upper layer mattress member 10 disposed on the lower layer mattress member 1 occupies the central portion in the width direction with the fifth member 11 made of soft urethane 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 lower mattress member 1 does not change. That is, as a mattress in which the upper mattress member 10 is overlaid on the lower mattress member 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. become. 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 harder part than a waist | hip | lumbar part (buttock part). The leg part is supported by a part having the same hardness as the back part. 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.

  Thus, in the case of the mattress in which the lower layer mattress member 1 and the upper layer mattress member 10 are laminated, the patient's buttocks are supported by the softest part (hardness 50 to 130N), and the back and leg parts are from the buttocks part. It is supported by a hard part, and the thigh is supported by a part harder than the back and leg parts. For this reason, this mattress is easy for the patient to turn over, and the patient's buttocks are supported by the portion having a hardness of 50 to 130N, so that the body pressure dispersibility is excellent, and the sleeping comfort and body pressure dispersibility are excellent. Both have an excellent balance. In addition, since the hard sixth member having a hardness of 150 to 500 N is arranged at the bed end sitting position, as described above, the patient can easily get out of the bed. Therefore, the combination of the lower layer mattress member 1 and the upper layer 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.

  On the other hand, when the upper mattress member 20 is used in combination with the lower mattress member 1 instead of the upper mattress member 10, the seventh member 21 having a hardness of 50 to 130N and the eighth member having a hardness of 150 to 500N are used. 22 is 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, so that the hardness is also the same. It is gradually decreasing. 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 lower mattress member 1 are combined, the body pressure dispersibility is extremely excellent, and 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 this is combined with a single lower layer mattress member 1 that is used in common, and has desired characteristics. Get a mattress. 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 lower mattress member 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, since the mattress characteristics can be easily customized at a low cost and optimal for the bed user, the mattress characteristics of the hospital and nursing care bed and the home care bed can be easily optimized. It can be adjusted to things, making a great contribution to the optimization and cost reduction of care.
