Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a floor support mechanism for a bed for a patient or the like.

(Prior art and its problems) When using a body support device such as a pinerest, when lying supine for a long period of time, blood flow in capillaries is inhibited by the pressure at the contact area with the body support surface, and cells are damaged. Pressure ulcers are likely to occur mainly due to necrosis. Therefore, for patients who are at risk of developing pressure ulcers, we turn them over at intervals of about two hours, or so-called position changes, and this change of position is highly effective in preventing pressure ulcers. It has been proven that there is.

Such a change in position is normally performed by one caregiver while supporting the patient's weight, but this is a task that requires considerable force and places an extremely heavy physical burden on the caregiver. In particular, in the case of home-based medical treatment, the majority of caregivers are middle-aged and elderly women, and the above-mentioned repositioning work is a heavy burden, so they have no choice but to cut corners. Bedsores often occur, causing problems not only for patients but also for their caregivers. For this reason, there is a need for a bed that allows the user to easily change their body position.

The present invention has been made in view of the above points, and it is an object of the present invention to provide a floor support mechanism for a bed that allows for easy body position changes.

(Means for Solving the Problems and Embodiments) The structure of the present invention for achieving the above-mentioned objects will be explained with reference to FIGS. 1a, b, and c corresponding to embodiments. The floor plate 1 of the bed is divided into three parts in the width direction and connected to each other in a flexible manner, and the central floor part 1b is swingably supported on the floor support 3 with its central part as a fulcrum 2, and the end part The floor parts 1a and 1c have support arms 6 on the central floor part 1b side.
a, 6c are vertically disposed, and an interlocking link 7 is connected between the lower sides of the support arms 6a, 6c so as to constitute a parallelogram mechanism together with the central floor portion 1b, and the interlocking link 7 is connected to the floor support 3. The end portion of the driving arm 8, which is configured to be dynamically drivable, is rotatably fixed to a connecting position 9 between the supporting arms 6a, 6c and the interlocking link 7, thereby configuring a bed floor support mechanism.

(Operation and Examples) Next, the operation of the present invention will be explained with reference to figures showing examples.

A shows a normal supine state, and all floor portions 1a, 1b, and 1c are supported in one plane. Such planar support is provided by the floor support 3 via the aforementioned parallelogram mechanism and the drive arm 8, thus allowing the patient 1 lying supine on the floorboard 1 to
When changing the body position of 0, first move the drive arm 8 to b.
When the supporting arm 6c and the interlocking link 7 are rotated counterclockwise as shown in FIG.
rises on the trajectory of the end of. As the connection position 9 rises, the connection position between the right end floor portion 1c and the center floor portion 1b rises, and at this time, the center floor portion 1b swings on the floor support 3 with its center as the fulcrum 2. Since it is movably supported, it rotates counterclockwise and the left side in the figure tilts downward. Due to the inclination of the central floor portion 1b, the support arm 6a of the left end floor portion 1a is connected to the central floor portion 1b and the interlocking link 7.
and the support arm 6c of the right end floor portion 1c, and the left end floor portion 1a is eventually inclined with the left side upward as shown in b. Therefore, the floor portion 1a on the left end side and the floor portion 1b in the center are undulating in the shape of a valley.

In this way, the nurse can easily further turn the patient 10 over in the inclination direction due to the inclination of the central floor portion 1b, similar to the mechanism described above, and at this time, the nurse can easily turn the patient 10 over in the inclination direction, and at this time, The floor portion 1b of the bed is undulating in the form of a valley, allowing the user to safely turn over. After the patient 10 is placed at a substantially right angle to the horizontal plane in this way, the drive arm 8
By rotating clockwise to return to the original position, the end side floor portions 1a, 1c and the central floor portion 1b can be brought into a flat state. can be raised almost perpendicularly to the horizontal plane as shown by the imaginary line a.

Contrary to b, c shows a state in which the driving arm 8 is rotated clockwise and the connecting position 9 of the supporting arm 6c and the continuous link 7 is lowered on the trajectory of the end of the driving arm 8. In this state, the center floor portion 1b rotates clockwise about its center as the fulcrum 2, and the right side in the figure inclines downward, and the right end floor portion 1c
is inclined with the right side facing upward, so that the floor portion 1c on the right end side and the floor portion 1b in the center rise in a valley shape. In this way, the patient 10 can be turned over in a similar manner to the above-described operation.

Note that the floorboard to which the mechanism of the present invention is applied may be the entire floorboard of a bed, or may be a part of the patient's 10 centering around the waist. Also, the central floor part 1b
It is preferable that the width is approximately the width of the torso of a human body, but it can be set as appropriate based on this width.

(Effects of the Invention) The present invention has the following features:
It is divided into two parts and connected together in a flexible manner, and the central floor part is swingably supported on the floor support with the central part as a fulcrum. The patient can be easily turned over in the direction of the inclination of the central floor part, and at this time, the floor part on the end side of the inclination side and the central floor part are undulating in the shape of a valley, so it is safe. This has the effect of allowing you to turn over in your sleep. After the patient is placed at a nearly right angle to the horizontal plane in this way, by supporting the patient in this state and making the end-side floor parts and the central floor part flat, the patient can be placed in the horizontal plane while the floorboards are flat. Thus, the present invention allows a patient lying supine on a bed to
Even a single caregiver can change the body position very easily, which has the effect of greatly contributing to the prevention of pressure ulcers. In particular, in the present invention,
Since the end-side floor sections are always connected to the central floor section, unlike a configuration in which they are separated, there is no inconvenience such as the patient's body being pinched, and such movements are not possible. The support of the floor section on the end side is made possible by a support arm hanging vertically on the floor section side and an interlocking mechanism connected between the lower side of this support arm so as to form a parallelogram mechanism together with the central floor section. Since it is configured using a link and a driving arm,
The mechanism for performing the tilting operation and the support mechanism are integrated, which has the effect of simplifying the configuration.
