Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a nursing bed.

[0002]

2. Description of the Related Art In a nursing bed, a back bottom can be raised and lowered in order to support a state in which a patient has an upper body raised. However, in the conventional nursing bed, the position of the waist bottom is fixed, and the back bottom is mounted independently of the waist bottom so that it can be raised and lowered and moved in the motor block direction. In the care bed having such a structure, when the back bottom is moved from the horizontal state to the standing state, the back bottom moves in the headboard direction, but the position of the waist bottom does not change. Therefore, in a patient whose body cannot be freely moved, the lower end of the back bottom becomes a position corresponding to the abdomen of the patient as the back bottom stands up. As a result, the back bottom rises, and the abdomen is strongly pressed. Therefore, in order to raise the back bottom to the state where the upper half of the patient is raised, it is necessary for the caregiver to move the position of the patient's waist to the back bottom side to relieve pressure on the abdomen.

As a solution to the above-mentioned problems, there has been proposed a structure in which the connecting portion between the waist bottom and the back bottom is constructed in the shape of a slats so that the length of the portion can be changed. However, even in this structure, the abdominal pressure can be relieved, but the movement of the waist position toward the foot is inevitable, and the movement of the patient by the caregiver is essential.

[0004]

DISCLOSURE OF THE INVENTION The present invention is designed so that the position of the patient's waist is located at the lower end of the back bottom regardless of the ups and downs of the back bottom, and the patient's abdomen is compressed when the back bottom is raised. The problem is to solve the problem.

[0005]

According to the present invention, in a care bed in which a back bottom is attached to a motor block so as to be capable of undulating, a lower end of the back bottom is rotatably attached to a waist bottom, and the waist bottom is the motor. It is characterized by being attached so as to be movable along the block.
As the mounting structure for the waist bottom, means for mounting a roller guide on the motor block, mounting waist bottom rollers on both sides of the waist bottom, and mounting the waist bottom roller on the roller guide can be considered (claim 2). The waist bottom is preferably provided with a mattress fixing means on its upper surface so that the mattress moves together with the waist bottom when the waist bottom moves (claim 3).

[0006]

In the present invention, the waist bottom is movable along the motor block, and the waist bottom is attached to the waist bottom. Therefore, when the waist bottom is moved from the horizontal position to the standing position, the waist bottom and the waist bottom are moved together. The bottom also moves toward the headboard. Therefore, the waist of the patient is always located at the lower end of the back bottom regardless of the state of the back bottom, and the back bottom does not press the abdomen. Further, in the invention of claim 3, since the mattress is fixed to the waist bottom, the waist bottom and the mattress are not displaced, and the patient's waist on the mattress always moves together with the waist bottom. The position shift is reduced as much as possible.

[0007]

BEST MODE FOR CARRYING OUT THE INVENTION Referring to FIG. 1, a supporting frame 27 is attached to a base 1 via a height adjusting arm 2.
The tenter frame 28 is attached to one end thereof, and the headboard 4 is attached to one end thereof. A tenter frame 28 and a footboard 5 are attached to the other end of the support frame 27. A motor block 3 is attached to the support frame 27, and a first bottom 6 and a second bottom 7 supporting a leg of a patient are connected to a foot board 5 side of the motor block 3 so as to be capable of undulating. Installed. A waist bottom 8 is attached above the motor block 3 independently of the first bottom 6, and a back bottom 9 is connected to the waist bottom 8 on the headboard side via a rotary shaft 10.

The waist bottom 8 supports the waist of the patient, and the waist bottom rollers 1 are provided on the lower portions of both sides of the waist bottom 8.
The waist bottom roller 11 is mounted in a groove of a rail-shaped roller guide 12 mounted on the motor block 3, and the waist bottom 8 is movable along the motor block 3.

The back bottom 9 supports the back and head of a patient, and the lower end thereof is attached to the waist bottom 8 by a rotary shaft 00 so as to be able to rise and fall. The undulating device for the back bottom 9 is configured as follows. In FIG.
A base end of a back-raising drive rod 14 is rotatably attached to the tip of a rod 13a of an actuator 13 attached below the motor block 3, and this back-raising drive rod 1
The tip of 4 is fixed to the central portion of the back-raising rotary shaft 15 which is installed between the motor blocks 3 on both sides. A base end portion of a back raising flat bar 16 is rotatably attached to both sides of the back raising rotary shaft 15, and a back raising roller 17 is attached to a tip end of the back raising flat bar 16. A raising roller 17 is attached to a groove of a rail-shaped roller guide 18 attached to the back bottom 9 in parallel with the motor block. Further, a base end portion 19a of a fixed rod 19 is rotatably attached to the headboard side of the back raising rotary shaft 15 of the side frame, and a tip end portion 19b of the fixed rod 19 is attached to an end portion of the back bottom 9. It is rotatably attached. In FIG. 1, reference numeral 20 is a back bottom receiver attached to the tenter frame 28. In addition,
In addition to the above, a known structure can be appropriately adopted as the undulating device for the back bottom.

With the above construction, when the rod 13a of the actuator 13 is retracted, the back bottom 9 becomes horizontal (FIG. 2), and when the rod 13a is pushed out, the back raising flat bar 16 rotates in the direction of arrow 21 in FIG. , The back raising roller 17 moves the roller guide 18 to the right in the figure,
The back bottom 9 stands up. Flat bar for raising the back 1
6, the distance between the back-raising rotary shaft 15 and the rotary shaft 10 to which the back bottom 9 is attached decreases, and the rotary shaft 10 moves in the direction of arrow 22 (headboard direction) in FIG. Moving. Here, since the waist bottom 8 is connected to the back bottom 9 via the rotating shaft 10, and the waist bottom 8 is independent of the second bottom 7, the waist bottom roller 11 guides the roller guide 12. It moves and moves in the same direction as the back bottom by the same distance.

As shown in FIG. 6, a hook-and-loop fastener 23 is attached to the upper surface of the waist bottom 8 as a mattress fixing means, and a hook-and-loop fastener 25 corresponding to the hook-and-loop fastener 23 is also attached to the back surface of the mattress 24. It is attached (Fig. 7). Reference numeral 26 in FIG. 7 is a nylon belt for preventing extension of the mattress. The fixing means of the mattress is not limited to the above, and snap hooks and buttons can be used.

To use the care bed of this embodiment, the patient is laid on the bed with the back bottom 9 shown in FIG. 2 horizontal, and the patient's waist is positioned on the waist bottom 8.
When the actuator 13 is operated from this state to raise the back bottom 9, the waist bottom 8 moves in the headboard direction together with the back bottom 9 as described above. In this way, since the patient's waist placed on the waist bottom 8 also moves with the waist bottom 8 and the back bottom 9, the patient's waist is located near the back bottom rotation shaft 10 regardless of the movement of the back bottom 9. The abdomen is not located at the lower end of the back bottom 9.
Therefore, even if the patient cannot move by himself, the abdomen is not pressed when the back bottom is moved to the standing position.

Further, by fixing the mattress 24 to the waist bottom 8, the waist bottom 8 and the mattress 24 are not displaced, and the lower surface of the mattress 24 is lifted from the waist bottom 8 regardless of the ups and downs of the back bottom 9. (If not fixed, the mattress will bend at the bend as the back bottom rises, causing the hip position to shift). Therefore, the shift of the waist position due to the displacement between the mattress and the waist bottom and the bending of the mattress is prevented, and the compression of the abdomen is further effectively prevented.

[0014]

According to the present invention, in a care bed in which a back bottom is attached to a motor block so as to be up and down, a lower end of the back bottom is rotatably attached to a waist bottom, and the waist bottom is attached to the motor block. Since it is mounted so as to be movable along the back, the waist bottom follows the lower end of the back bottom along with the ups and downs of the back bottom. Therefore, the back bottom does not push the patient's abdomen,
By raising the back bottom, the patient's upper body can be raised without difficulty. In the invention of claim 3, mattress fixing means is provided on the upper surface of the waist bottom,
Since the mattress moves along with the waist bottom when the waist bottom moves, the waist bottom and the mattress do not slip and the patient's waist position is kept constant.
