Description

  The present invention relates to a bed and a bed-combining tool that can replace a floor covering without lowering a bedridden from the bed.

  Patent Literature 1, Patent Literature 2, Patent Literature 3 and the like as a bed having a direct support mechanism for various problems in daily life such as excretion processing and bed slippage prevention of bedridden persons who have impaired motor function or cognitive function Is already known.

  The bed disclosed in Patent Document 1 has a back rest, a seat rest, a lower leg rest, and a foot rest to which a divided mattress is attached, and is converted into a chair shape. It can be excreted from the opening provided in the center by sitting on the rest to the lower toilet, and the opening can be opened and closed by a lid that slides in the front-rear direction. In the bed disclosed in Patent Document 2, the bed is divided into an upper bed and a lower bed in the longitudinal direction so that each can be moved in any direction, and a pair of left and right knee lifters are moved up and down on the upper bed foot side. It can be provided, and this makes it easier to clean the lower abdomen by raising the legs of the bedridden person. Patent Document 3 discloses that both sides of the sheet spread so as to cover the bed floor surface are alternately left and right or left and right by two sets of drive mechanisms provided symmetrically with respect to the center line in the bed longitudinal direction. It is a bed that moves up and down at the same time, and changes the posture of the bedridden by making the body support surface of the seat horizontal, tilting, or making it U-shaped open upward, thereby preventing bed slippage. .

  Each of these beds is useful, but they all have similar weaknesses. The weakness is that, firstly, each bed can provide only a limited part of the various support that the bedridden needs. Secondly, each support device has the possibility of making it difficult to solve other problems or impairing the performance of the bedclothes required for the bed.

  The bed of Patent Document 1 can provide effective support for excretion processing before the bedridden person's disability is severe. However, when incontinence becomes a normal situation, it becomes difficult to deal with it, which may cause problems. That is, since it is difficult to remove the dirt around the seat on the structure, the sanitary condition is deteriorated, and the structure around the seat may induce a waist floor slip. Since the bed of the patent document 2 is provided so that the storage place of the knee lifter protrudes from the left and right sides toward the longitudinal center line, there is a possibility that the performance as the bedding required for the bed is basically impaired. high. In addition, since this structure restricts the position change of the bedridden person, the occurrence of bed slip is feared. The bed of Patent Document 3 is intended to prevent fixation of a body compression point by changing the body position and prevent bed slipping of a severely handicapped person who has been prolonged. However, in order to prevent bedsores, it is important not only to prevent immobilization of the pressed part, but also to protect the skin from dirt and excessive moisture due to sweat, urine, and feces. Therefore, having no effective support measures other than the bedridden position change is insufficient as a measure to prevent bed slipping.

  As support for “motion support” to help with back-up and standing-up movements, direct support for solving various life problems such as excretion and bed slippage is here. We will call it “outside support”. In the future, when the aging of society is rapidly progressing, it is expected that a bed equipped with an operation support mechanism having high practicality as well as an operation support mechanism will be further demanded.

For bedriddens with disabilities, there are three important items in their daily life: cleaning the bedding, excretion at each stage of the physical condition, and preventing bed slipping. The cleaning of bedding is a fundamental factor that affects the health of the bedridden and the surrounding hygiene, and the excretion process is always a problem for the bedridden, and bed slippage has a serious impact on the health of the bedridden. Effect. Therefore, in order to have a non-operation support mechanism that can withstand practical use, it is necessary to be able to provide effective support for at least all the important items.

  There are many types of out-of-motion assistance needed by bedridden people with disabilities, and their nature is also varied. Furthermore, as the physical condition of the bedridden changes, the content of the required support changes. For example, bedsore prevention support, which is very important in a severe disability period, is unnecessary in a mild disability period. In addition, in the excretion processing support, the type of support required differs for each stage of the physical condition, and the type of support currently required becomes unnecessary in another stage. Therefore, a bed where the out-of-motion assistance that can be provided is too limited is not very useful in practice, even if the quality of the assistance is high. In order to be a bed with a practical out-of-motion support mechanism, it must be able to provide a wide range of out-of-motion support needed by the bedridden without compromising the bedclothing function that the bed should originally have. .

  A bed that can easily replace a floor covering having a predetermined size, shape, and quality necessary for incorporating various support functions is one of the beds having a highly practical out-of-motion support mechanism. Because if the bed can be easily replaced, it is possible to easily use various types of laying tools with different functions according to the situation, thereby requiring a bedridden person including support for the important items. This is because it is possible to provide a wide range of non-operational support. Here, “bedclothes” refer to all items placed on a support plate for the bedridden to use on the body. Not only various bedclothes, but also excrement tools and massage tools used on the support plate.・ Includes bedsore treatment tools. “Replacing the laying material” means changing the laying material without taking the bed person down from the bed.

  Although there are some exceptions, most of the out-of-motion support, including support for the above important items, is fully provided by a dedicated function built into a structure that is almost the same size and shape as a normal mat. Is something that can be done. Moreover, in general, development of various types of coverings incorporating such a support function can be realized relatively easily and inexpensively only by using existing technology. Therefore, if the bed can easily replace the laying with the size, shape, and quality necessary to incorporate the various support functions, you can easily use the various linings depending on the situation. As a result, it is possible to provide a wide range of out-of-motion support required by the bedridden, including support for the important items, without compromising the bedding function that the bed should originally have. is there.

  The laying piece is divided in the longitudinal direction, and at least the upper body part, the seating part and the lower leg part are separately formed, and these constitute the entire laying piece. This will be referred to as “split laying”. If split lining is used, it is difficult to replace only the seat lining that is the lining used for the seat, including the upper lining used for the upper body and the lower limb lay used for the lower leg. Can be easily replaced. This is because the upper body lay can be replaced by raising the upper body of the bedridden, and the lower leg bedcloth can be replaced simply by moving the bed of the bedbed. Therefore, in the bed using the divided laying device, if the seat laying device can be replaced, the entire laying device can be replaced.

  A bed that can be used with a split lay having a predetermined size, shape, and quality, and that can easily replace the seat lay in the split lay, I will call it. If you develop a sitting bed laying replacement bed that can be used with a split lay that has the required size, shape, and quality to incorporate various support functions, the bed can be replaced as a whole. Therefore, as described above, the bed is provided with a highly practical out-of-motion support mechanism. In other words, if you develop a seating bed laying replacement bed that can use split laying with the prescribed size, shape, and quality required to incorporate various support functions, a highly practical out-of-motion support mechanism can be created. A bed can be provided.

  Leaving the bed for night flights is not desirable for the elderly, even when healthy. This is because it often causes some diseases such as heart disease, and the risk is particularly high in cold weather. A toilet bed, which is a combination of a toilet bowl and a bed, is effective in protecting yourself from such serious illnesses as it eliminates the need to leave the bed for stool. Can be said to be a bed that is inherently useful regardless of the presence or absence of disability. However, at present, elderly people living without disabilities rarely use toilet beds for the purpose of disease prevention. This is largely because a bed with a toilet bowl that can be used comfortably even when healthy is not yet developed.

  To be a bed with a toilet that can be used comfortably by a healthy person, first of all, there is no worry that the bedding will get dirty due to the use of the toilet, and second, the bedridden will not have to get out of the bed. Four conditions are satisfied: the toilet can be used easily with the operation of the third, third, that the toilet can be used in a stable and comfortable position, and fourth, that the toilet used is a flush toilet like a normal product. Need to be.

  In the bed part replacement bed, the bedbed person on the bed must perform the conversion work to the dedicated toilet seat, that is, the work of pulling out the seat cover used and replacing it with the dedicated toilet seat bed. The conversion work can be further simplified by taking some measures. Therefore, the seat bed laying replacement bed can satisfy all of the above four conditions if a flush toilet can be installed under the seat and the toilet can be used from the bed in an easy posture. Therefore, even when healthy, it can be used as a bed with a toilet that can be used without resistance. That is, if a flush toilet bowl can be installed under the seat and a seat bed mat replacement bed that can be used in a stable and comfortable position from the support plate is developed, However, as a bed with a toilet that can be used without resistance, it can protect the elderly from dangerous serious illnesses and contribute to maintaining the health of the elderly.

  The problem to be solved by the present invention is a bed or the like in which a predetermined divided lay can be used, and the seat lay in the divided lay can be easily removed without lowering the bedridden from the bed or the like. It is to develop a seat laying bed replacement bed etc. that can be replaced. In addition, a bed etc. means bed combined use tools, such as a bed and a bed combined use health implement, a bed combined exercise tool.

The seat bed laying replacement bed or the like according to claim 1 includes an upper body plate that is a support plate that supports a portion above the upper body portion, that is, the seat portion, and a portion from the seat portion, that is, the lower part of the spine to a predetermined position of the thigh. The seat plate that supports the lower leg and the lower leg plate that supports the lower leg, that is, the portion below the seat, are formed separately, and the upper body part, the seat part, and the lower leg part are used as laying tools. Beds etc., each of which is a laying stool having a predetermined size, shape and quality, and which is used by mounting the upper body laying stool, the sitting laying wrapping and the lower leg laying wrap on the respective support plates,
Exercise means for causing each movement predetermined support plate to perform five support plate movements called first movement, second movement, third movement, fourth movement, and fifth movement;
Under the body of the bedridden person, the sitting floor covering can be removed from the bed or the like and attached to the bed or the like, at least at the stage where the third movement is completed,
An opening that allows the seat covering to be removed from the underbody's body to the left, right, or at least one of the front and back, and at least the third movement is completed. The structure secured at the stage
It comprises.

  Here, the form when a bed or the like is used as a normal bed is called the basic form of the bed, etc., and the position occupied by each member such as a support plate or laying in the basic form of the bed or the like It is called the basic position. The left-right direction is the width direction of the bed when the bed is in the basic form, and the front-back direction is the longitudinal direction of the bed when the bed is in the basic form. The vertical direction is a direction indicated by a straight line that is perpendicular to both the straight line in the left-right direction and the straight line in the front-rear direction. In addition, although the front refers to the foot side in the front-rear direction and the rear refers to the head side in the front-rear direction, when simply referred to as “front”, it means “straight forward or diagonally forward”. Similarly, the rear means “straight rear or diagonally backward”, the upper means “straight upward or diagonally upward”, and the lower means “straight downward or diagonally downward”.

  The details of the five movements are as follows. In the first movement, the lower leg plate moves from the state in which the bed or the like is in the basic form until at least the rear end of the lower leg plate is located above the seat covering in the basic position while satisfying the following conditions: It is exercise. The first of the above conditions is that the lower leg plate moves without generating a new factor that impedes replacement of the sitting laying material. The replacement of the seat laying means that the seat laying is replaced without taking the bed person down from the bed or the like. The second of the above conditions is that the lower leg plate moves while maintaining a state in which the bedridden who lies on the bed or the like can safely place his / her legs on the lower leg laying apparatus without difficulty. In the second movement, the lower leg plate moves rearward so that the rear part of the lower leg plate overlaps the upper part of the seat laying piece at the basic position with a gap while satisfying the following two conditions: It is an exercise that follows one exercise. The first of the two conditions is that the lower leg plate moves without generating a new factor that impedes replacement of the sitting laying material. The second of the two conditions is that the lower leg plate moves while maintaining a state in which the bedridden who lies on the bed or the like can safely place his / her legs on the lower leg covering material. In addition, the exercise | movement following 1st exercise | movement means the exercise | movement started in the state in which the important part for solution of the subject of this invention is hold | maintained among the effects which the 1st exercise | movement brought about. The third motion is a motion following the second motion in which the seat plate moves downward from its basic position without generating a new factor that hinders replacement of the seat covering. The movement following the second movement is a movement started in a state in which a part important for solving the problem of the present invention is held among the effects brought about by a series of movements from the first movement to the second movement. Yes, all the following similar terms have the same meaning. The fourth motion is a motion following the third motion in which the seat plate moves to its basic position while maintaining the state where the seat covering is mounted. In the fifth exercise, the lower leg plate moves to its basic position while maintaining the state where the bedridden who lies on the bed etc. can comfortably and safely put his / her legs on the lower leg covering material, It is an exercise following the fourth exercise that returns to the basic form.

  The method of removing the seat laying tool from the bed etc. under the body of the bedridden person on the bed etc. may be the method of removing only the seat laying tool from the seat board, or the seat laying tool together with the seat board. The method of removing from etc. may be sufficient. However, each of the two has advantages and disadvantages. For example, the method of removing the entire seat plate has the advantage of increasing the degree of freedom in developing the bedding because it makes it difficult to remove the bedding and allows replacement of both the seat bedding and the seat plate. is there. Therefore, it seems that it is more desirable to be able to remove by any of the above-mentioned methods so that it can be used properly according to the situation. In addition, when removing the seat covering sheet from the bed or the like together with the seat panel, an opening having a size that allows the seat covering sheet to be removed together with the seat panel is secured at least when the third movement is completed. It is necessary to

  When the bedridden is lying on the bed etc., the sitting lie is pressed down by the weight of the bedridden, so to speak, the upper and lower surfaces are strongly clamped by the bedside of the bedded person and the seating laying attachment part. It is in the state that was done. The state in which the upper and lower surfaces are sandwiched is inevitably generated due to the nature of the tool called a laying tool, and naturally occurs in the upper body laying tool and the lower leg laying tool. However, in the case of a sitting laying device, it is possible to reduce or eliminate the pinched state by changing the position of the bedridden person who moves the leg or raises the upper body due to the characteristics of the position where it is placed. difficult. For this reason, it is difficult to replace the sitting laying material without lowering the bedridden from the bed or the like. In addition, the seat laying material is sandwiched between the lower leg lining material and the upper body lining material that are close to each other on the front and rear surfaces, and this is also a factor that hinders the replacement of the sitting laying material.

  The seat bed laying replacement bed or the like according to claim 1 is configured so that each motion predetermined support plate or the like performs five motions from the first motion to the fifth motion, so This eliminates the pinched state and allows the seat laying material to be easily replaced without lowering the bedridden from the bed or the like. That is, first, by the first motion, the lower leg laying piece that is in close contact with the front surface of the sitting laying piece is separated upward, and the sandwiched state of the two front and rear faces is eliminated. Next, in the second exercise, the lower leg plate is pushed toward the thigh while the leg of the bedridden is bent, and the lower body of the bedridden is supported via the lower leg laying so that the lower body is not lowered. By exercising, the seat plate is moved downward to eliminate the pinched state of the upper and lower surfaces, and the seat covering can be replaced. In the fourth movement, the seat plate and the seat covering are moved to the respective basic positions, and in the fifth movement, the lower leg plate and the lower leg covering are moved to the respective basic positions, and the bed is basically used. Return to form. The first exercise works to eliminate the pinched state of the two front and rear surfaces, and at the same time, pushes the feet of the lying bedside up and guides the bedridden person to a position that can easily cope with the second movement. Is to do.

The seat bed laying replacement bed or the like according to claim 2 includes an upper body plate that is a support plate for supporting the upper body portion, that is, a portion above the seat portion, and a seat portion, that is, a portion from the lower part of the spine to a predetermined position of the thigh. The seat plate that supports the lower leg and the lower leg plate that supports the lower leg, that is, the portion below the seat, are formed separately, and the upper body part, the seat part, and the lower leg part are used as laying tools. Beds etc., each of which is a laying stool having a predetermined size, shape and quality, and which is used by mounting the upper body laying stool, the sitting laying wrapping and the lower leg laying wrap on the respective support plates,
Exercise means for causing each movement predetermined support plate to perform five support plate movements called first movement, second movement, third movement, fourth movement, and fifth movement;
Under the body of the bedridden person, the sitting floor covering can be removed from the bed or the like and attached to the bed or the like, at least at the stage where the third movement is completed,
An opening that allows the seat covering to be removed from the underbody's body to the left, right, or at least one of the front and back, and at least the third movement is completed. The structure secured at the stage
It comprises.

  Here, the form when a bed or the like is used as a normal bed is called the basic form of the bed or the like, and the position occupied by each member such as a support plate or laying in the basic form of the bed or the like is the member. It is called the basic position. The center of the bed is the center of the bed when the bed is in the basic form, and the horizontal direction is the width direction of the bed when the bed is in the basic form. The front-rear direction is the longitudinal direction of the bed when the bed is in the basic form, and the up-down direction is perpendicular to both the straight line in the left-right direction and the straight line in the front-rear direction. The direction indicated by the straight line. In addition, although the front refers to the foot side in the front-rear direction and the rear refers to the head side in the front-rear direction, when simply referred to as “front”, it means “straight forward or diagonally forward”. Similarly, the rear means “straight rear or diagonally backward”, the upper means “straight upward or diagonally upward”, and the lower means “straight downward or diagonally downward”.

  Moreover, the shape which united the projection part formed by projecting the lower leg board in the basic position and the lower leg part laying in the left and right directions into one, and the seat board in the basic position and the stool laying down. Each of the projections formed by projecting in the left and right directions is combined with the shape of the upper 2 and the projections formed by projecting the seat plate and the seat covering in the basic position in the vertical direction are superimposed. The shape is referred to as B-2.

  Of the five movements, the lower leg plate moves in the first movement, the second movement, and the fifth movement, but the lower leg board moves on the lower leg of the bedridden person. There must be no danger of being forced into an unreasonable posture or dropping a foot. Therefore, in these movements in which the lower leg plate moves, the lower leg plate is moved through the movement range, with a specific three-dimensional interior composed of two rectangular parallelepipeds as the lower leg plate movement range.

One of the rectangular parallelepipeds constituting the lower leg plate moving area is a rectangular parallelepiped that satisfies the following conditions on the lower surface and the upper surface. The first condition to be satisfied by the lower surface is a plane that passes through the center of the bed etc. and is perpendicular to the left-right direction, has a center on the reference plane, one side indicates the left-right direction, and the other side indicates the front-rear direction. It is a rectangle, and the longitudinal length is 50 mm longer than the maximum lateral length of the lower leg plate, and the longitudinal length is 300 mm longer than the maximum longitudinal length of the lower leg plate. The second condition is that it is a rectangle with a vertical projection distance of 30 mm between the second end 2. The vertical projection distance means a distance between a projection unit and a projection unit that are projected in the vertical direction. The third condition is that the seat is in front of the seat plate in the basic position and is a rectangle located 150 mm below the upper surface of the seat plate. Further, the condition to be satisfied by the upper surface is that it is a rectangle located 250 mm above the upper surface of the seat laying material in the basic position.
Another rectangular parallelepiped that constitutes the lower leg plate movement area is a rectangular parallelepiped that satisfies the following conditions on the front surface, the lower surface, and the upper surface. The condition to be satisfied by the front surface is that it is a rectangle having a center on the reference plane and in contact with the rear surface of the rectangular parallelepiped, one side showing a horizontal direction, and a horizontal length equal to the horizontal length of the rectangular parallelepiped. A condition to be satisfied by the lower surface is that the lower surface is a rectangle having a longitudinal length of 300 mm, located above the upper surface of the seat laying lie at the basic position. The condition to be satisfied by the upper surface is that the rectangle is located 150 mm above the upper surface of the seat covering in the basic position.

The details of the five movements are as follows. In the first movement, the lower leg plate first moves into the lower leg plate moving area while satisfying a specific condition from the state where the bed or the like is in the basic form, and then at least the rear end of the lower leg plate is at least It is a movement that moves through the lower leg plate moving area until it is located above the seat covering. Here, the movement of the lower leg plate through the lower leg plate moving area means that the lower leg plate moves while keeping all the portions of the lower leg plate in the lower leg plate moving area. The first of the specific conditions to be satisfied by the first movement is that the lower leg plate moves without generating a new factor that impedes replacement of the sitting laying material. Here, the replacement of the seat covering is to replace the seat covering without lowering the bedridden from the bed or the like. The second condition is that the lower leg plate moves while maintaining a state in which a line segment connecting two points arranged in the left-right direction on the upper surface of the lower leg plate at the basic position indicates the left-right direction. The third condition is that in the process of moving the lower leg plate into the lower leg plate moving area, the contact portion of the upper 1 with the upper 2 is separated from the upper 2 forward, and the lower leg plate is moved to the lower leg plate. It is to move within the moving area. Here, separating the contact portion of Instep 1 forward from Instep 2 means moving the contact portion of Instep 1 forward and away from Instep 2 while avoiding that the contact portion of Instep 1 overlaps with Instep 2. To do. The fourth condition is that the upper 1 is kept away from the upper 2 in the process of moving the lower leg plate through the lower leg plate moving area until at least the rear end of the lower leg plate is positioned above the seat covering. However, the lower leg plate moves. Note that the first movement when the lower leg plate in the basic position is in the lower leg plate movement area from the beginning eliminates the process of moving the lower leg board into the lower leg plate movement area. That is, the lower leg plate is moved from the state in which the bed or the like is in the basic form until at least the rear end of the lower leg plate is positioned above the seat covering while satisfying the first, second and fourth of the above conditions. It becomes exercise to do.
The second movement is a state in which the line segment connecting the two points arranged side by side on the upper surface of the lower leg plate when in the basic position indicates the left and right direction without generating a new factor that hinders the replacement of the sitting laying material. The lower leg plate moves backward through the lower leg plate movement area so that the rear part of the lower leg plate overlaps the upper part of the seat laying piece while keeping the lower leg plate. Here, the movement following the first movement is a movement started in a state where an important part for solving the problem of the present invention is held among the actions brought about by the first movement.
The third motion is a motion following the second motion in which the seat plate moves downward from its basic position without generating a new factor that hinders replacement of the seat covering. The movement following the second movement is a movement started in a state in which a part important for solving the problem of the present invention is held among the effects brought about by a series of movements from the first movement to the second movement. Yes, the following similar terms have the same meaning.
The fourth motion is a motion following the third motion in which the seat plate moves to its basic position while maintaining the state where the seat covering is mounted.
In the fifth motion, the lower leg plate passes through the lower leg plate moving area while the line connecting the two points arranged side by side on the upper surface of the lower leg plate when in the basic position indicates the left and right direction. This is a movement following the fourth movement in which the bed or the like returns to the basic form.

  The method of removing the seat laying tool from the bed etc. under the body of the bedridden person on the bed etc. may be the method of removing only the seat laying tool from the seat board, or the seat laying tool together with the seat board. The method of removing from etc. may be sufficient. However, each of the two has advantages and disadvantages. For example, the method of removing the entire seat plate has the advantage of increasing the degree of freedom in developing the bedding because it makes it difficult to remove the bedding and allows replacement of both the seat bedding and the seat plate. is there. Therefore, it seems that it is more desirable to be able to remove by any of the above-mentioned methods so that it can be used properly according to the situation. In addition, when removing the seat covering sheet from the bed or the like together with the seat panel, an opening having a size that allows the seat covering sheet to be removed together with the seat panel is secured at least when the third movement is completed. It is necessary to

  When the bedridden is lying on the bed etc., the sitting lie is pressed down by the weight of the bedridden, so to speak, the upper and lower surfaces are strongly clamped by the bedside of the bedded person and the seating laying attachment part. It is in the state that was done. The state in which the upper and lower surfaces are sandwiched is inevitably generated due to the nature of the tool called a laying tool, and naturally occurs in the upper body laying tool and the lower leg laying tool.

  Non-operational support required by bedridden persons with disabilities, that is, direct support for life problems other than movement, such as cleaning of bedclothes and excretion, is diverse and varies according to the physical condition of the bedridden person It is a thing. With the aging of society, the need for beds with out-of-motion support mechanisms is increasing, but conventional beds are a limited part of the variety of out-of-motion support required by the bedridden. Therefore, all of them have the weakness of lacking practicality.

  In the seat laying material replacement bed or the like of the present invention, all the laying materials including the seating laying material can be replaced, that is, the bedridden person can be replaced without being lowered from the bed or the like. Therefore, it is possible to easily replace and use various types of coverings with functions necessary for non-operation support according to the situation, thereby providing a wide range of non-operation support required by the bedridden. it can.

  The seat laying bed replacement bed etc. of the present invention makes it possible to easily replace and use various types of laying sheets having a support function outside the operation, thereby preventing obstacles without impairing the bedding function that the bed should originally have. The present invention provides a bed and the like having a highly practical out-of-motion support mechanism that can perform a wide range of out-of-motion support required by the bedridden person.

  Most out-of-motion assistance is related to the seat. Accordingly, it is desirable that various types of seat coverings can be used. In the seat part laying material replacement bed or the like according to claims 3 and 4, first, even if the laying material thickness is thinner than a predetermined thickness, it can be used without any trouble. Moreover, even if the laying material thickness is thicker than a predetermined value, it can be used as long as it is within the range of the limitation due to the laying material descending depth of the third movement according to each of the above claims. Furthermore, it is possible to use the seat plate directly, that is, to use the seat plate without the laying device as it is instead of the laying device.

  If a sanitary device or the like is installed below the seat plate and the sanitary device or the like can be used with the replaced special laying material, it becomes possible to provide more effective outside support. The seat bed laying replacement bed or the like according to claim 5 can use predetermined equipment under the seat, that is, predetermined hygiene equipment / medical equipment, etc. installed under the seat from above the bed etc. with a dedicated floor covering. It is.

  The sitting bed laying replacement bed or the like according to claim 6 or 7 is a sitting bed laying replacement bed or the like having the following three characteristics, and can provide a wide range of excellent off-operation support and health. As a bed with a toilet bowl that can be used without resistance even at any time, it is useful for maintaining the health of the elderly.

The first of the three characteristics is that the seat plate can be used directly, that is, the seat plate without the laying tool can be used as it is instead of the laying tool. If you compare the replacement work between sitting seat coverings that replace the sitting seat covering in use with another sitting floor covering, and the work that switches the sitting seat covering to the direct use of the seat plate, the latter Is much easier to work with. In the former case, it is necessary to remove the existing rug before inserting it, while in the latter case, it is not necessary to completely remove the used rug. This is because the seat plate can be lifted and used while leaving the end portion of the seat. In particular, considering the case where a bedridden on a bed or the like replaces himself / herself, the difference in workability between the two becomes more remarkable. Therefore, in beds that can be used directly, it is easy for the bedridden on the bed to perform their own operations by using a seat plate that has been properly processed to use the equipment under the seat. You can use the equipment under the seat.
The second of the above characteristics is that the bedridden person can sit on the seat plate. As a result, the bedridden person can use the device under the seat while sitting on the seat plate.
The third of the characteristics is that the seat plate can be lowered within a predetermined range. The optimum position for using a sanitary device or the like installed under the seat is usually at a position where the seat plate is slightly lowered from the basic position. Therefore, the bedridden person can adjust the height of the seat plate and use the sanitary equipment under the seat at the optimum position by the third characteristic.

  For bedriddens with disabilities, there are three important items in their daily life: cleaning the bedding, excretion at each stage of the physical condition, and preventing bed slipping. A specific description will be given of how the seat laying bed replacement bed according to claim 1 or 2 can specifically support each of the above items.

  First, the cleaning and maintenance of the bedclothes can be quickly dealt with by replacing the dirty bedclothes in use with the spare bedsheets that have been prepared in advance. This support is very effective because the bedding is updated immediately if the bedding is replaced with a repaired one.

Next, for assistance in excretion processing, here, for convenience, the physical condition of the bedridden is divided between a mild stage where there is no worry of incontinence and a severe stage where incontinence has become normal, and an intermediate stage that is an intermediate state of both. Simplify and explain in three steps. It is mainly defecation that becomes a problem in the excretion processing in the mild stage. While urination at this stage can be handled without difficulty in the posture of a bedridden person using a suitable urine collection tool, stool is extremely unnatural when using a simple toilet on a futon. This is because an unstable posture is forced, and there are problems such as pain in the contact portion with the toilet bowl, which often causes great problems for the bedridden. In the seat laying tool replacement bed or the like, for example, a laying tool as shown in FIG. 56 can be used at the time of defecation. This lay has a main body in which a seat mat B is mounted on a wooden base A, and a toilet C which is freely detachably combined with the main body. The structure is very simple. However, since the seat is wide and it is installed directly on the seat plate, the stability is sufficient, so that it is much better than the conventional case where a simple toilet is used on a futon. Can be given to. In addition, the use feeling can be further enhanced by using a laying tool that can raise the base after the bedded person sits on the laying sheet.
In the excretion process in a severe period in which diapers are usually used, the workability of exchanging diapers and cleaning the lower abdomen becomes a practical problem. In the above-mentioned bed part replacement bed, etc., the diaper can be easily exchanged by utilizing the movement of the bed, etc. when the seat part lay sheet is replaced, and the accompanying change in the position of the bedridden (FIGS. 19, 35, etc.). Can do. At this time, if a suitable tray is placed under the seat, the lower abdomen can be easily cleaned.
In the interim period, there is a possibility of incontinence, and urination processing is a stage in which there are many cases of failure in a method such as a mild stage. Conventional beds tend to start using diapers early to avoid excretory stains on bedding, especially laying. However, since wearing a diaper causes considerable mental distress to the bedridden, it is desirable to stop wearing it for a minimum period. In the above-mentioned bed stool replacement bed and the like, cleaning and maintenance of the laying material is basically simple, and for example, a laying material as shown in FIG. 57 can be used. It is possible to do this by simply wearing incontinence underwear. The laying material shown in FIG. 57 is composed of a base mat D that is waterproofed, five overlays E that are mounted on the base mat D, and a middle mat F that is disposed so as to be combined with the notch portion of the base mat. Both the overlay and the inner mat are detachable. In this laying tool, the inside mat can be removed, and a toilet as shown in FIG. 56 can be placed there. In addition, if a disposable sheet with water absorption is attached to the overlay and middle mat around the base mat notch, in many cases the stain of the laying equipment due to incontinence can be treated simply by replacing the sheet. There is no need to replace the tool itself.
56 and 57 is merely a simple and simple reference model shown for convenience of explanation, and in fact, a more convenient lay can be selected and used.

  Lastly, there is support for bedsore prevention. In order to prevent bedsores, it is necessary to comprehensively take measures such as preventing the body from pressing, and protecting the skin from sweat, urine, feces, and excessive moisture. In the above-mentioned seat laying bed replacement bed or the like, it is possible to prevent the compression point from being fixed by appropriately using various existing floor slip prevention mats. It is also possible to change the position of the bedridden so that the compressed portion is not fixed by using the movement of the bed at the time of replacement of the seat covering. Also, dirt and excessive dampness due to sweat, urine, and stool are most likely to occur around the seat. By utilizing the accompanying posture change of the bedridden person, it is easy to treat the area around the bedside of the bedridden person to keep it clean.

The upper body leg 1c includes an upper body base 110 and an upper body support 120 fixed to the upper part of the upper body base 110, and the seat leg 1d includes a seat base 130, And a lifting plate 140 attached to the base of the seat portion so as to freely move up and down. The elevating plate 140 includes a follower 141 at the lower part of the outer surface. The lower leg leg 1g includes a lower leg base leg 150, a rotating plate 160, a moving leg 170, a rotating arm 180, and a connecting body 190. As shown in FIG. 9, the rotating plate 160 includes a follower 161 and a moving leg operator 162, and is pivotally attached to the inner surface of the lower leg base 150 by a shaft 151. As shown in FIG. 10, the moving leg 170 includes moving leg members 171, 172, and 173, and the moving leg member 173 is pivotally attached to the upper ends of the moving leg members 171 and 172 by shafts 174 and 175. The lower ends of the moving leg members 171 and 172 are pivotally attached to the outer surface of the lower leg base leg 150 by shafts 152 and 153. The lower leg plate support surface of the moving leg member 173 is parallel to the substrate 1a, and the four axes 152, 153, 174, and 175 form a parallelogram having one side parallel to the substrate 1a. As shown in FIG. 11, the rotating arm 180 includes an arm front wheel 184, a lower leg plate joint receiving part 182, and a lower leg plate stator hole 183. The rotating arm 180 is pivotally attached to the moving leg material 173 by a shaft 181, and the left and right arms are coupled and integrated by a connecting body 190 including a pair of connecting body legs 191. The upper body plate 1k and the lower leg plate 1n are each composed of a support plate body and a laying plate application plate. The upper body plate 1k and the seat plate 1m are attached to the respective leg bodies by attachment means that do not move in a parallel direction with respect to the support surface but can be easily detached if lifted in a right angle direction. The lower leg plate 1n is attached to the rotating arm 180 so that the pair of left and right joints 231 pass through the joint receiver 182, respectively. The lower leg plate 1n includes a wheel 232 and a lower leg plate fixing device at left and right end portions. As shown in FIGS. 13 and 14, the lower leg plate fixing device includes a lower leg plate stator 234, a handle 235, a handle support 236, and a spring 237 that urges the support 236 rearward. Yes. When the claw portion of the stator 234 pivotally attached to the side wall of the apparatus housing portion falls in the stator hole 183 of the rotating arm, the rear end of the pull support 236 presses the stator 234 from above, so that the lower leg plate 1n does not move. On the other hand, when the handle 235 is moved forward from this fixed state, the handle support 236 moves forward to release the upper portion of the stator 234, so that the stator 234 can be rotated and the lower leg plate 1n moves forward. It becomes like this. Therefore, if the handle 235 is pulled forward, the lower leg plate 1n moves forward, and if the lower leg plate 1n is returned to a predetermined position by pulling the handle 235 backward, the lower leg plate 1n is fixed. The operation of the puller 235 is performed with, for example, a pull string that is stretched over the left and right pullers. The drawstring hung over the handle can also be used as a hook processing means when the seat laying piece is replaced. The attachment means for the upper body part 1p, the seat part 1q and the lower leg part 1r is usually a hook-and-loop fastener. If the bedding is special and it is not appropriate to use a hook-and-loop fastener, it can be dealt with by replacing the seat plate or the backing plate. Any of the seat plate 1m, the contact plate 210, and the contact plate 240 can be easily replaced. In addition, since it is necessary to attach and remove the seat part laying tool 1q under the seating part of the bedridden person, the seat part laying means attaching means is provided only on the laying tool replacement side. Since the seat laying material is originally in a state of being difficult to move because it is sandwiched between other lining materials, such a mounting method does not cause a problem. As shown in FIGS. 3 and 4, the driving device 1t has a prime mover 250 attached to each of a pair of left and right screw shafts 270 that use 280 as a power source via screwed runners 260.
