Description

  The present invention relates to a bed apparatus that allows a cared person to easily excrete while lying on a bed body on his / her back.

  For example, for a cared person such as an elderly person requiring long-term care or a long-term care patient, keeping the body clean is an important purpose of daily life. However, in the case of a non-caregiver who is difficult to move the body, there are cases where effort is required even when taking a single excretion, and it is not easy to carry out the above purpose. In addition, since the body cannot be moved in a so-called bed-ridden state, it is difficult to maintain a posture suitable for excretion, which makes the situation more complicated. The present inventor has been working on the problem of long-term care, and from his experience, he has obtained knowledge that, for example, a person can hardly urinate or defecate when lying on his back. In other words, we found the fact that urination and defecation are difficult to urinate if left on the back, but urination and defecation can be facilitated if the posture is slightly raised.

  On the other hand, looking at the bed apparatus currently proposed, for example, utility model registration No. 3075497 aims at letting a bedridden elderly man evacuate to a toilet in the same manner as a normal person, but for that purpose one bed Is divided into three parts, and the middle part is further divided into three parts. Moreover, although it is necessary to raise the upper body of the cared person, it is unclear how to hold the upper body of the cared person with the back support necessary for this purpose, and it is considered that practical use is not easy. Japanese Patent Laid-Open No. 10-113364 has a width-diameter opening in which a buttock of a person lying on the bed body is placed, and a flush toilet is disposed below the opening, and urination and defecation are performed while the care recipient is lying down. As described above, it is difficult to urinate and defecate while sleeping. Japanese Patent Laid-Open No. 2002-10951 moves the slide sheet covering the opening of the stool container backward to enable urination and defecation when not in use. . Thus, the above-mentioned knowledge is not yet known, and it is judged that a bed apparatus that can practice this knowledge is not provided.

Utility model registration No. 3075497 JP 10-113364 A JP 2002-10951 A

  The present invention has been made paying attention to the above points, and its object is to make it possible for a cared person to easily excrete while lying on his / her back on the bed body. Moreover, the other subject of this invention is providing the bed apparatus with easy excretion which can be used comfortably also for a cared person and a caregiver.

In order to solve the above-mentioned problems, the present invention relates to an apparatus that allows a cared person to excrete while lying on his / her back on the bed body, and the bed body includes an upper half part that supports the upper body of the cared person It has two parts of the lower half that supports the lower body and is arranged on the pedestal, and the undulation mechanism provided between the pedestal and the lower half and the upper half from a substantially flat state to a substantially flat bottom The upper half can be raised and lowered to an inclined state where the upper half rises at an angle of several to 60 degrees with respect to the half,
At least on the upper surface of the lower half of the bed body, a covering mat is detachably provided at a place that supports the waist of the cared person, and an excretion port for dropping excrement at the bottom of the bed body when the covering mat is removed. Means is provided in the lower half (the invention according to claim 1).

  A problem recognized in the present invention is how to make urination and defecation of a cared person who is lying on his / her back on the bed body suitable. As described above, the inventor has obtained the knowledge that raising the upper body and taking it into effect is effective for urination and defecation. Therefore, the present invention is a bed apparatus that realizes this knowledge.

  In order to achieve the above-described knowledge, in the present invention, a bed body including two parts, an upper half part supporting the upper half of the cared person and a lower half part supporting the lower half, is arranged on the pedestal. The pedestal is the part that supports the bed body. The upper body is defined as the upper part from the waist and the lower body is defined as the lower part from the waist (according to "Kojien"). It is unclear whether the waist belongs to the upper body, the lower body, or neither. In the above, the means and configuration relating to excretion shall be equipped in the lower half. These upper and lower halves are desirably joined by means such as hinges at their respective ends, and may be considered normal, but need not necessarily be joined.

  The lower half and the upper half can be undulated from an almost flat state to an inclined state where the upper half rises from several degrees to 60 degrees, preferably 15 to 30 degrees with respect to the substantially flat lower half. Is formed. The range of the angle at which the cared person is raised is also based on the inventor's knowledge. In many cases, if the upper half is inclined at an angle of 15 to 30 degrees, the effect of the cared person's rising will appear. As a result, urination and defecation are reduced. Although the causal relationship of this phenomenon is not clear, as is often said, the position of the sigmoid colon approaches the anus perpendicularly due to the inclination of the upper body, or the function of muscles related to the large intestine, anus, urethra, etc. This is thought to be promoted. Therefore, if the upper body is raised beyond 60 degrees, urination and defecation will not be disturbed, but if it is up to 60 degrees, the posture of the cared person's upper body will be stable even if someone does not support it. On the other hand, if it is more than that, it will start up too much and the posture will become unstable, so the above angle is defined as the limit for obtaining stability.

  A hoisting mechanism is provided between the base frame and the hoisting operation. It is desirable that the bed main body is arranged on the pedestal, and as a hoisting mechanism, one end of the hoisting drive device is attached to the base and the other end is attached to the upper half of the bed main body. invention). In the first aspect of the present invention, the purpose is to raise the upper body of the cared person and make the upper body feel like it is, and in order to achieve the purpose, it is sufficient that only the upper half can be raised and lowered. The piston-cylinder device is an example of a driving device for undulations, but the operation sound is relatively quiet and a smooth operation can be easily obtained. Therefore, the piston-cylinder device is also suitable for the purpose and application of the present invention.

  In the present invention, a covering mat is detachably provided at a position that supports the waist of the cared person on the upper surface of at least the lower half of the bed body, and excrement is dropped at the bottom of the bed body when the covering mat is removed. Is provided in the lower half. The excretion opening is indispensable as a means and configuration relating to excretion in the present invention, and is arranged at the position of the lower half of the bed body in order to adapt to the position of the urethral opening and anus of the care recipient. The excretion opening is covered with a mat when not in use, and a sewage recovery unit is disposed below the excretion opening. A toilet seat can be provided around the excretion opening, and the toilet seat is provided so as to make contact with the cared person's body safe and prevent discomfort, and is formed using a material that can withstand washing.

  The pedestal of the bed body is provided on the bed base, and includes a fulcrum that supports the center of the pedestal, and a rolling drive device disposed on the left and right of the fulcrum. It is desirable to have a structure for supporting turning over that can be tilted. This is because, in order to perform urination and defecation using the device of the present invention, the covering mat is removed, but the covering mat can be removed by changing the posture of the cared person by the above-mentioned turning support structure. is there.

  Such a bed body is provided with a detachable bed mat arranged on the entire surface of the base frame and the upper surface thereof, and the bed mat at a position for supporting the upper body has a groove-shaped portion in the central vertical direction. It can be configured so that the spine portion of the cared person can be accommodated therein (the invention according to claim 4). Some care recipients have a spine that protrudes more than the surface of the back and may cause pain if they are sleeping in a supine position and continue to be pressed, but the position of the spine that protrudes into the groove-shaped part above This problem can be solved by combining the two. In addition, when a bed mat is provided in a place other than the portion covering the excretion opening, it is preferable that the bed mat can be attached to and detached from the bed main body because it is possible to clean the bed main body, but the attachment and detachment is not an indispensable requirement. .

  Since the present invention is configured and operates as described above, the upper half of the bed body is raised to a desired angle while lying on the back of the bed body, thereby being a bedridden caregiver. However, there is an effect that it can be excreted relatively easily. Further, according to the present invention, the care recipient is not forced to overload during urination and defecation, and the caregiver continues to support the body of the care recipient or changes the direction of the body. Therefore, it is possible to provide an easily excreted bed apparatus that can be used very comfortably.

  Hereinafter, the present invention will be described in more detail with reference to the illustrated embodiments. FIG. 1 shows an example of an easily excreted bed apparatus 10 according to the present invention. In order to allow a care recipient to excrete while lying on the bed main body 11 on his / her back, The upper half 12T supporting the upper half of the caregiver and the lower half 12B supporting the lower half are provided.

A hair washing space 24 is provided at a position corresponding to the bedside at the upper end of the upper half 12T of the bed main body, and the waste water is also flowed to the sewage receiver.

  In the bed main body 11, the lower half 12B and the upper half 12T are substantially flat and the upper half 12T is several degrees to 60 degrees from the substantially flat lower half 12B, preferably 15 degrees. It is formed to be able to undulate up to an inclined state where it rises at an angle of ˜30 degrees. For the above undulation operation, undulation mechanisms are provided on both sides of the bed body 11 between the upper half base frame 13T. The bed main body 11 is arranged on the pedestal, and in the example shown in the figure, as a raising / lowering mechanism, a raising / lowering drive device 25 comprising a piston cylinder device is used, and one end 25a is attached to the pedestal 20 and the other end 25b is attached to the bed main body. 11 is attached to the upper half 12T. With this configuration, the upper half 12T is inclined by, for example, an angle of 15 to 30 degrees, thereby having a rising effect on the cared person's body, thereby reducing the cause of troubles in urination and defecation. Become.

  In the illustrated example, the bed body 11 is provided on a pedestal 20, and the pedestal 20 is provided on a bed base 26. The pedestal 20 includes a fulcrum 27 that supports the center thereof, and rolling drive devices 28L and 28R arranged on the left and right of the fulcrum.

A link rod 31 is pivotably connected to the middle of the arm, and a link arm 32 is connected to the link rod 31. Since the link arm 32 is connected to the mounting shaft 33 of the bed mat 14, the bed mat 14 can be rotated alternately forward and reverse.

  FIG. 5 shows an example of a method that can change the swing motion of the floor rubbing prevention mechanism 29. That is, when the rotating bodies 34 of the adjacent bed mats 14 are connected by the parallel link 35, the adjacent bed mats 14, 14 are swung in the same direction (the left half in FIG. 5), When connecting with the cross link 36, the adjacent bed mats 14 and 14 can be swung in a contrasting direction (the right half of FIG. 5). As shown in the left half of FIG. 5, when the adjacent bed mats 14 and 14 are swung in the same direction, the cared person can be tilted to the left and right, so that the same actions and effects as turning over are provided. Can be obtained. In addition, the code | symbol 37 in a figure has shown hand rubbing, and arbitrary numbers are provided in the required location of the bed main body right and left.

  The bed apparatus 10 of the present invention has the above-described configuration, so that even a cared person who is lying on his / her back on the bed body 11 operates an operation unit (not shown) and has an upper body. In this way, it is possible to create a state in which it is easy to urinate and defecate physiologically and promote excretion. In order to obtain the above state, the covering mat 17 can be removed. For this purpose, it is not necessary to lift the body of the care recipient, and if the turning support device is activated, the body in the supine posture can be turned to the left or right. Therefore, the covering mat 17 can be removed in the meantime. The same operation can be performed when the removed covering mat 17 is mounted again.

  The above-mentioned turning support device is used to support a care recipient and a caregiver when the caregiver who cannot move his / her body by hitting a bed is turned on, and to reduce his / her efforts, As a result, it is possible to reduce the adverse effects of being in a sleeping position. In addition, floor rubbing that is unavoidable for a caregiver who is lying down can be reduced by changing the point of contact with the body at any time by the floor rubbing prevention mechanism 29.

  In the bed apparatus 10 of the present invention, the pedestal 20 also serves as a sewage receptacle, and the toilet seat 21 is also formed of a water-resistant material, so that the body dirt after excretion can be completely washed.
