DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lower back washing chair suitable for seating a disabled person or a bedridden elderly person (hereinafter, simply referred to as "sick person, etc.") and washing the lower back.

[0002]

2. Description of the Related Art A technique of interest to the present invention is described, for example, in Japanese Patent Application Laid-Open No. 6-125965.
Here, a waist-washing device that enables simple bathing for a sick person or the like is described. The waist-washing device includes a waist-washing chair for sitting a sick person or the like. In addition, this lower back washing apparatus, while sitting on a lower back washing chair, in order to wash the lower body of the sick, etc., in order to spray water toward the lower body of the sick, etc. from all around as much as possible. In addition to having a plurality of injection ports, a housing is provided to cover the lower body of a sick person or the like in order to prevent the water from scattering around.

[0003]

In order to enhance the cleaning effect of such a lower back washing apparatus, the seat provided on the lower back washing chair has, for example, an opening while receiving the buttocks of a sick person or the like. By making it into a mesh shape, water is allowed to flow from the injection port, and the water can reach the buttocks.

[0004] However, when this lower back washing apparatus is actually used, washing of the buttocks can be performed only inadequately in spite of the adoption of the above-described structure allowing the flow of water in the seat. There was no time. This is known only when the sick person or the like stands up from the lower back washing chair after washing, and sometimes excreta remains on the buttocks. Therefore, the sick person or the like must be seated again on the lower back washing chair and the washing must be repeated.

[0005] It has been found that incomplete cleaning as described above is likely to occur when the crotch of a sick person or the like sitting on a lower back cleaning chair remains closed. Therefore, if the crotch of the sick or the like seated in the lower back washing chair is sufficiently opened, the problem of incomplete washing can be considerably solved, but actually, for the following reasons, It is sometimes difficult to open the crotch of a sick person or the like.

That is, the reason why the washing is performed by the lower back washing apparatus while sitting on the lower back washing chair is as follows.
Like a normal bath, you can not enter the bathtub,
This is because the sick and the like often have severe illness, and therefore may not have enough power to maintain the state in which the crotch is widened. Also, when the sick person is in a dementia state, even if there is a force to keep the crotch open, the crotch cannot be kept open by one's own intention. Often, you get stuck.

As described above, when the crotch of a sick person or the like is closed, it is conceivable that the caregiver lends power to open the crotch, but the lower back provided with a housing covering the lower body of the sick person or the like is considered. When the cleaning device is used, once the cleaning is started, the caregiver cannot care for the sick or the like from the outside, and thus may end the cleaning with the crotch closed.

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to improve the washing effect on the hips of the human body to be washed under the waist, so that the crotch of a sick person or the like can be easily maintained in an open state. Trying to provide a chair.

[0009]

SUMMARY OF THE INVENTION The present invention is for seating a human body to be cleaned under the lower back, and includes a seat portion for forming a seat for receiving a buttocks of the human body, and each leg of the human body. And a footrest for forming a footrest surface for receiving the sole of the back, which is directed to a lower back washing chair, in order to solve the above-mentioned technical problem, the footrest surface is placed here. Each of the feet is provided with a slope that makes the inside of the sole of the foot higher than the outside.

[0010] In the present invention, the height relationship between the seating surface and the foot resting surface is such that, when the buttocks are placed on the seating surface and each foot is placed on the foot resting surface, the front of the thigh of the human body is relatively high. It is preferable that the part is set so as to float from the seat. In the present invention, the inclination given to the footrest surface is:
Preferably, it is selected in the range of 15 to 20 degrees with respect to the horizontal plane.

Further, in the present invention, it is preferable that the seat surface has a structure that allows the flow of water.

[0012]

As described above, according to the present invention, the foot rest surface for receiving the sole of each foot of the human body, which is formed on the footrest provided in the lower back washing chair, is placed here. Since the inside of each sole is inclined so as to be higher than the outside, the crotch of the human body seated on the lower back washing chair can be naturally spread.

[0013] Therefore, the crotch cannot be spread by its own power, and even if it is severely sick, etc., it is not possible to maintain this spread state. Even a sick person or the like who cannot expand their crotch by their own intention, if the chair for washing under the waist according to the present invention is used, the crotch will be naturally expanded, so that the crotch will be maintained in an expanded state. It becomes easy to put.

Thus, irrespective of the condition of the sick person, sufficient water can be reliably circulated toward the buttocks of the sick person, and the cleaning effect on the buttocks can be enhanced. Further, according to the present invention, the natural opening of the crotch of the human body can be basically achieved only by the inclination of the footrest surface. Therefore, in order to forcibly open the crotch, for example, it is not necessary to rely on means such as interposing any member between the kneecaps, so that the member for opening the crotch, rather than obstructing the washing, It does not cause such a problem. In addition, for example, it is conceivable that the foot rest surface of the footrest is widened and the interval between both feet is widened to force the crotch to open. However, in this case, since the width dimension of the lower back cleaning chair becomes large, handling of the lower back cleaning chair becomes complicated, but according to the present invention, such a problem is not encountered. .

In the present invention, the height relationship between the seating surface and the foot resting surface is such that, when the buttocks are placed on the seating surface and each foot is placed on the foot resting surface, the thigh is relatively forward of the human body's thigh. If the part is set to float from the seat, the kneecaps of the human body can move relatively easily in the lateral direction, so that the crotch is opened more reliably and more according to the inclination of the footrest surface. Can be easily enforced. Also, when the relatively forward part of the thigh of the human body is lifted off the seat, a space is formed between the thigh and the seat that allows water to pass through. Contributes to the improvement of the cleaning effect.

In the present invention, if the inclination provided to the footrest surface is selected in the range of 15 to 20 degrees with respect to the horizontal plane, the crotch can be securely and sufficiently provided without causing pain to the sick or the like who is seated. Can be opened. Further, in the present invention, the above-described effects are more favorably exhibited when the seating surface has a structure that allows the flow of water.
