On the other hand, a running gear (pinion) 112 as a rear wheel for moving the toilet 100 is provided on each of the left and right sides on the leg side of the bed of the toilet 100. Each of the running gears 112 is connected by a shaft 116, meshes with the racks 82 and 87 described above, and moves on the racks 82 and 87. A pulley 114 is provided on the side of the traveling gear 112 disposed on the right side of the shaft 116, and the pulley 114 is connected to a pulley 118 by a belt 117. The pulley 118 is used to rotate the running gear 112
00 is connected to the output shaft of a motor 119 installed in the motor. Therefore, the rotational force due to the driving of the motor 119 is
Running gear 112 from pulley 118 via belt 117
Is transmitted to Also, the traveling gear 112 disposed on the right side
Is connected by a belt 120 to a traveling gear 113 disposed on the right side, and the rotation of the traveling gear 112
13 is transmitted. The central portion of the shaft 116 and the motor 119 are accommodated and fixed in the housing 121. The operation of moving the toilet 100 is as follows.
For example, the operation can be automatically performed by operating an operation box (not shown) that can be operated while the patient 5 is lying on the bed.

Next, the specific operation of the nursing care bed 1 will be described in detail. The operation procedure of the nursing care bet 1 described below is an example, and the present invention is not limited to this.

When the patient 5 lying on the nursing care bed 1 excretes, first, the operation box at hand of the patient 5 is operated to drive the motor 26. By this operation, the screw shaft 24 is rotated via the pulley 27, the belt 28 and the pulley 25. The rotation of the screw shaft 24 moves the nut 60 toward the head of the bed, and the angle between the arm 73 and the arm 74 increases. By this operation, the upper body mat 11 is raised with the connection portion with the buttocks mat 13 as a fulcrum. At this time, the buttocks mat 13 remains fixed, and only the upper body mat 11 is raised, so that the patient 5 can be easily raised in a stable state. The angle of the upper body mat 11 is adjusted with the substantially central position of the opening 30 as a fulcrum,
The recess 16 allows the waist of the patient 5 to escape to the head side of the bed, so that the alignment between the buttocks of the patient 5 and the opening 30 is very simple. When the upper body mat 11 reaches the desired inclination angle of the patient 5, the driving of the motor 26 is stopped.

Next, the operation box is operated to drive the motor 45. By this operation, the pulley 46,
The shaft 41 rotates via the belt 48 and the pulley 43, and the shaft 42 rotates via the pulley 47, the belt 49 and the pulley 44. As a result, the right cover mat 33 is rotated about 90 degrees downward about the shaft 42 as a fulcrum, and the left cover mat 34 is rotated about the shaft 41 as a fulcrum, so that both are open (see FIG. 5). Thus, the opening 30
Open. In this state, the driving of the motor 45 automatically stops.

Next, the operation box is operated to drive the motor 119. By this operation, the pulley 11
8, running gear 1 via belt 117 and pulley 114
12 is rotated. The rotation of the traveling gear 112 is transmitted to the traveling gear 113 via the belt 120, and the traveling gear 113 also rotates. Thus, the traveling gear 11
The racks 2 and 113 move on the racks 81 and 82 toward the head of the bed. The running gear 113 is provided on the vertical portion 92 of the rack 82, and the running gear 112 is provided on the vertical portion 91 of the rack 81.
, The running gears 112 and 113 are raised by meshing with the teeth formed on the vertical portions 91 and 92, and the toilet seat 101 is fitted into the step portion 31 of the buttocks mat 13. As a result, the excrement receiving port 101a is
Set to 0. The toilet 100 is fixed in this position (see FIGS. 5 and 6). Here, the thickness of the opening 30 can be reduced by the presence of the stepped portion 31, so that the side wall of the opening 30 can be minimized from being stained during excretion.

Next, the operation box is operated to drive the motor 52 according to the preference of the patient 5. By this operation, the screw shaft 50 is rotated via the pulley 53, the belt 54, and the pulley 51. Due to the rotation of the screw shaft 50, the nut 64 moves to the leg side of the bed, and the thigh mat 14 is raised with the joint portion with the buttocks mat 13 as a fulcrum by the same operation as the arm mechanism 71 described above. At this time, the leg side end surface of the lower leg mat 15 moves from the leg side to the head side of the bed on the mat placing plate 21e, and the inclination angle is changed. Thereby, the knee of the patient 5 is bent (see FIG. 6). When the thigh mat 14 reaches the desired inclination angle of the patient 5, the driving of the motor 52 is stopped. Note that this operation may be performed as needed, and this operation is not performed when excretion is desired only by raising the upper body mat 11.

Next, by operating the operation box, air is discharged from the fumarole 57 of the thigh mat 13, and
From 8, the air around the patient 5 is sucked. By this operation, it is possible to prevent the patient 5 from rubbing on the floor and deodorize during excretion. Moreover, comfortable excretion can be performed by warming the temperature of the discharged air as needed.

With the above operation, the preparation for excretion is completed.

When the excretion is completed, the operation box is operated to wash the patient 5 with the washing device 110. At this time, the cleaning liquid is warmed to about the body temperature of the patient 5, and comfortable cleaning can be performed.

Next, the operation box is operated to discharge the cleaning liquid from the cleaning liquid outlet 131 to clean the toilet 100. At this time, the cleaning liquid is stored in the lower part of the toilet 100 in advance, and it is possible to prevent the excrement from adhering to the toilet 100 to some extent, so that the amount of the cleaning liquid can be minimized. By this operation, the weight of the filth stored in the toilet 100 is reduced at the fulcrum 108 by the weight 107.
, The opening and closing valve 105 is inclined downward to open the discharge port 102, and the waste is discharged into the storage bag 103. The waste discharged into the storage bag 103 is solidified by a coagulant. When the waste in the toilet 100 is discharged, the weight of the waste becomes lighter than the weight of the weight 107 at the fulcrum 108, and the on-off valve 105 returns to the original position. Thereafter, an appropriate amount of cleaning liquid is again stored in the lower part of the toilet 100.

Next, by operating the operation box, the motor 1 is rotated so that the pulley 118 rotates in the direction opposite to the above.
After the toilet 19 is driven to lower the toilet 100, the bed is moved to a predetermined leg-side position (original position).

Next, the operation box is operated to drive the motor 45 so as to rotate the shafts 41 and 42 in the opposite direction. By this operation, the right lid mat 33 is supported by the shaft 42 as a fulcrum,
4 rotates about 90 degrees upward with the shaft 41 as a fulcrum, and closes the opening 30 by the projection 40. (Figure 2
reference). In this state, the driving of the motor 45 automatically stops.

In the present embodiment, at this time, the air is discharged from the blowhole 57 of the buttocks mat 13 and
Although the suction (deodorization) of the air from 8 was stopped, this may be performed at a desired time.

Next, the operation box is operated to drive the motor 52 so that the screw shaft 50 is rotated in the opposite direction to the above, and the thigh mat 14 is returned to the original state. At this time, the leg side end surface of the lower leg mat 15 moves from the head side of the bed to the leg side on the mat mounting plate 21e, and is returned to the state shown in FIGS.

Next, by operating the operation box, the motor 26 is driven so that the screw shaft 24 is rotated in the opposite direction to the above, and the upper body mat 11 is returned to the original state.

With the above operation, the patient 5 is again turned on as shown in FIG.
And as shown in FIG. 4, it will be in an original state (state of lying down).

Here, the storage bag 103 attached to the toilet bowl 100 that has been returned to its original state is removed from the toilet bowl 100 and discarded. At this time, since the waste in the storage bag 103 is in a hardened state, it does not spill out of the storage bag 103 and can be sanitarily and easily discarded. Thereafter, the same storage bag as described above is attached to the toilet 100.

In this embodiment, the upper body mat 1
1, the upper body mat 11 is configured such that the inclination angle is changed with the fulcrum about the substantially center position of the opening 30 of the buttocks mat 13, but the present invention is not limited to this. The tilt angle of the upper body mat can be freely adjusted, and a portion corresponding to the buttocks of the patient in the lower body mat is provided with an opening that can be opened and closed, and when the opening is opened, the toilet moves and the It is sufficient that the opening is closed when the toilet faces the opening and the toilet bowl retreats.

The mechanism for adjusting the inclination angle of the upper body mat 11 and the thigh mat 14 described in the present embodiment is merely an example, and the upper body mat 11 and the thigh mat 14 are different from the other mechanisms. It is needless to say that the inclination angle may be adjusted by utilizing the same.

Further, in the present embodiment, the thigh mat 14 is raised so that the patient 5 stands up (see FIG. 6). However, the present invention is not limited to this. Alternatively, the lower leg mat 15 may be lowered and the patient 5 may be seated on a chair without changing the inclination angle (in a state where the lower leg is fixed to the mat mounting plate).

Further, in the present embodiment, the configuration in which the racks 81, 82, 86 and 87 and the traveling gears 112 and 113 (pinions) are used to move the toilet 100 is not limited to this. The toilet may be moved by another configuration, such as moving the toilet horizontally using a combination of rails and wheels, and vertically using a lifting device.

In the present embodiment, the toilet 10
Although the structure in which 0 is moved from the leg side to the head side and from the head side to the leg side of the bet has been described, the present invention is not limited to this.
The toilet may be moved to the left and right of the bed. Further, in the present embodiment, a disposable bag is used as a storage unit for storing waste, but not limited to this, various forms such as using a detachable container or connecting the storage unit directly to sewage. Can be taken.

The present embodiment is an example. For example, a deodorizing device, a toilet cleaning mechanism, a patient cleaning mechanism, a blowing hole for preventing floor rubbing, a fume pipe, a gas supply device, etc.
It may be installed as desired, and its configuration can be freely determined.
