Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bed provided with a floor undulation mechanism, wherein the floor is displaced laterally of the floor to support the back of the patient while the patient is on the bed while supporting the back of the bed. So that it takes a sitting posture,
The present invention relates to a care support bed that reduces the burden on the caregiver and promotes the patient's independence.

[0002]

2. Description of the Related Art A bed provided with a floor undulating mechanism can oscillate the floor to take various postures.
Numerous qualities can be provided for both the patient and the caregiver, with the majority of beds now having undulating features on the floor.

[0003]

However, when a patient who has difficulty in supporting himself or herself wakes up the floor and back, the upper half of the body becomes extremely unstable, and the patient is left on the side of the bed. There is a risk of falling into. Therefore, when transferring such a patient from the bed to a wheelchair or the like, the caregiver supports the upper half of the body of the patient while raising the back bed and moves the legs laterally to move the bed floor end. I had to try to sit in the club. The present invention has been proposed in order to improve such a problem, in a bed provided with a floor undulation mechanism, when the floor wakes up, the floor is displaced laterally to the floor to move the patient to the bed. While supporting the patient's back while riding, the patient can move to the side of the bed and take a sitting posture to reduce the burden on the caregiver and promote the patient's independence. The purpose is to provide nursing care beds.

[0004]

In order to solve the above-mentioned problems, the present invention provides a bed provided with a floor undulating mechanism, which comprises a undulating back floor corresponding to the patient's back of the floor. together constituted by a Seyuka movable portion which is divided along the floor base and the bed longitudinal axis, provided with a rolling mechanism for raising and lowering the Seyuka movable portion to the back floor around the bed longitudinal central axis, the rolling mechanism Is the back base

[0005]

[Function] While the patient is lying down, the caregiver supports the upper half of the patient's upper body so as not to fall to the side while raising the floor. When the user finishes getting up, this time, the rolling mechanism attached to the back floor is activated to displace the back floor movable portion around the central axis in the bed longitudinal direction. At this time, the caregiver holds the patient's leg and shifts it to the side of the bed in accordance with the protrusion of the back bed. The patient's upper body is turned to the side of the bed, and the patient can take a sitting position at the end of the floor.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, a nursing care bed according to the present invention will be described below with reference to the accompanying drawings, with reference to an embodiment. 1 and 2 show a nursing care assist bed 1 according to the present invention. In this care assist bed 1, the floor 2 is the back floor 3,
It is divided into a waist floor 4, a knee floor 5, and a leg floor 6, and is equipped with a floor undulation mechanism (not shown). The floor undulation mechanism undulates the back floor 3,
It has a function of raising and lowering the connecting portion between the knee floor 5 and the leg floor 6.

The back floor 3 is divided into a back floor base 3a and a bed longitudinal center axis toward the side where the back floor 3 is connected, and is rotationally displaced about the bed longitudinal center axis. It is composed of a back movable part 3b. The back floor 3 is provided with a rolling mechanism 7 that undulates the back floor movable portion 3b around the central axis in the bed longitudinal direction (FIG. 3).
reference).

The rolling mechanism 7 is staggered with respect to the abutment surface, which is the split central axis of both split floor movable portions 3b, through a bearing portion 8 provided on the underfloor-facing side of the back floor base 3a. A support shaft 10 which is inserted into a bearing portion 9 provided to connect and support the back floor base portion 3a and the back floor movable portion 3b.
And the motor 11 connected to the support shaft 10 in the back floor base 3a, and the bearing portion 9 in both the back floor movable portions 3b.
Is attached to the support shaft 10 via the
and a support arm 12 that is brought into contact with b and interlocks with the support shaft 10 (see FIGS. 4 and 5).

The back movable part 3b is provided with a winding spring 13 which is fitted into the support shaft 10 and constantly urges the two movable back parts 3b in a flat state (see FIG. 6). ). Further, a groove 14 into which the support arm 12 is fitted is formed in the bearing portion 9 of each of the back floor movable portions 3b, and the support arm 12 is supported by the support shaft 12 via the groove 14.
I am trying to attach it to 0. The support arm 12 is interlocked with the rotation of the support shaft 10 to rotate the back floor movable part 3b (see FIG. 7).

The motor 11 may have, for example, a deceleration mechanism built therein so that the support shaft 10 can obtain a rotational driving force of about one rotation per minute. Alternatively, the driving force may be transmitted from the motor 11 to the support shaft 10 via the worm gear mechanism 15 (see FIGS. 8 and 9).

A nursing care auxiliary bed 1 constructed as described above.
First, the floor undulating mechanism is activated to wake up the back bed 3 with the patient lying down. At that time, the caregiver takes care so that the upper half of the patient's upper body does not fall to the side while raising the back 3. After waking up the back bed 3, this time,
The rolling mechanism 7 attached to the back floor 3 is activated. Then, the support shaft 10 is rotated by the motor 11, the support arm 12 is interlocked, and the back floor movable portion 3b is rotationally displaced about the support shaft 10 against the biasing force of the coil spring 13.
At this time, the caregiver holds the patient's legs and shifts them to the side of the bed in accordance with the protrusion of the back movable part 3b. The patient's upper body is supported by the rising back movable part 3b and is directed toward the side of the bed. You can Thus, in order to move the body of the patient, the upper body is raised by a normal floor undulation mechanism, and the back movable part 3b is attached to the back floor 3 to change the body direction to the bed side. Since it is achieved by activating the rolling mechanism 7 and raising it, the labor of the caregiver is greatly reduced. In addition, if the patient can support himself / herself to some extent, he / she can operate the patient himself / herself by lowering the legs to the floor at the end of the floor and taking a sitting posture. It can also be used as training for patients and can promote the patient's independence.

[0012]

As described above, according to the present invention, when the floor is raised, the floor is raised to the side of the floor to support the patient's back while the patient is on the bed, and the bed side is supported. Since the patient is moved to take a sitting posture, the burden on the caregiver can be reduced and the patient's independence can be promoted.
