Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to a bed equipped with a movable divided bed that is effective in preventing bedsores that tend to occur when living in bed.

(Prior Art) For example, patients undergoing long-term treatment spend a long period of time in bed, so they are more likely to develop pressure sores, which is a big pain for the patients.

Bedsores are said to occur due to the synergistic effects of lying on your back in the same position for a long period of time, which causes congestion in the skin on your back where the weight is particularly applied, and the combined effects of moisture, body grime, etc. .

Therefore, the caregiver must occasionally change the patient's position to change the weight-bearing areas of the back to eliminate prolonged back skin congestion.

To this end, in the past, the floor of the bed was divided into sections, and the adjacent floor sections were raised and lowered alternately at appropriate intervals to change the part of the back where the weight was particularly applied. There is.

(Problems to be Solved by the Invention) However, in such a bed, the floor portion must be subdivided to some extent. This is because if the division is rough (for example, about 4 divisions), the patient's body will be supported by the raised floor, and the back region will be unduly compressed by the end of the floor. This is because it may make sleeping uncomfortable for the patient. Moreover, since the floor part only moves up and down, the direction in which it is pressed remains the same, and therefore the area on the back, where the weight is particularly applied, does not change much and is not effective.

In addition, when subdividing the floor, the structure of the floor becomes complicated, and the floor is raised and lowered alternately, so
The drive mechanism is considerably stressed and requires a large drive torque, so that a drive power transmission mechanism has to be considered, especially in the manual case.

The present invention has been made in view of these points.

(Means for Solving the Problems) In order to achieve the above-mentioned problems, in the bed of the present invention, a plurality of strip-shaped divided beds are arranged in a row in the longitudinal direction of the bed to constitute a floor part, and each A rod-shaped support is provided protruding from the lower side of the divided bed, and the middle part of each rod-shaped support is supported on the bed frame so as to be swingable in the longitudinal direction of the bed. The rod-shaped supports were used as components of a parallel movement mechanism, and a common drive shaft was installed to simultaneously move the lower parts of the rod-shaped supports back and forth in the longitudinal direction of the bed.

(Function) When the lower part of each support body is simultaneously moved in the longitudinal direction of the bed frame by the drive shaft,
Since all the supports perform a parallel movement in which they rotate in the same direction using the fixed position of the intermediate portion as a fulcrum, the upper parts of these supports move simultaneously in opposite directions. Therefore,
The divided beds fixed on top of each of these supports move in the opposite directions mentioned above while tilting. If the direction of movement of each support body by the drive shaft is reversed, the divided bed tilts while moving in the opposite direction to the above movement.

For this reason, the part of the divided bed that supports the body's weight changes, which helps prevent bedsores.

(Example) Next, an example of a bed equipped with a movable divided floor according to the present invention will be described with reference to the accompanying drawings.

In the figure, reference numeral 1 denotes a bed equipped with a movable divided floor, and the floor portion of the bed 1 is constructed by arranging a plurality of band-shaped divided beds 2 in a row in the longitudinal direction of the bed 1.

A rod-shaped support 5 is provided protruding from the lower side of the divided bed 2, and the rod-shaped support 5 has an intermediate portion 10 rotatably attached to a bed frame 6, and extends in the longitudinal direction of the bed 1. It is supported so that it can swing freely. Therefore, the rod-shaped support 5 is connected to the bed frame 6 in the same way as the divided bed 2.
are arranged in rows in the longitudinal direction.

Further, a drive shaft 9 is installed in the longitudinal direction of the bed frame 6. In this embodiment, the drive shaft 9 is a screw shaft and is rotatably supported. A crank handle 3 is connected to one side of the end, which is the side of the footboard 4 in the figure. The drive shaft 9 has female threads 8 corresponding to each of the rod-shaped supports 5.
The lower part of the rod-shaped support 5 is rotatably connected to these female threads 8.

The operation of the above configuration will be explained next.

First, it is assumed that all the divided beds 2 are in a horizontal state as shown in FIG. 3a. In this state, when the caregiver operates the crank handle 3 to rotate the drive shaft 9, depending on the rotational direction of the crank handle 3, all the female screws 8 are rotated as shown in FIG. 3b, for example. They move all at once along the shaft 9 to the left in the figure. Therefore, all the rod-shaped supports 5 rotate clockwise in the figure using the intermediate portion 10 as a fulcrum due to parallel motion, so the divided bed 2 simultaneously moves to the right in the figure and tilts downward to the right. To go. Furthermore, when the direction of rotation of the crank handle 3 is reversed, all the female screws 8 simultaneously move to the right in the figure along the drive shaft 9, so all the rod-like supports 5 simultaneously move counterclockwise in the figure. As a result, the divided bed 2 simultaneously moves slightly to the left in the figure and tilts downward to the left.

In this way, a strip-shaped divided floor 2 is placed on top of each
By moving the plurality of rod-shaped supports 5 that support
Each of the divided beds 2 can be tilted at a predetermined angle in alternating directions, thus making it possible to change the part of the body of the patient lying supine on the bed on which the weight is applied.

The divided floor 2 can be tilted by rotating the rod-shaped support 5 in parallel motion about its intermediate portion 10, so the required force is smaller than when raising and lowering the divided floor up and down. Even if it is driven by the crank handle 3, it requires less labor and can be operated easily. The mechanism itself is also very simple, and the number of divided beds can be easily increased.

The drive shaft 9 may be driven by the crank handle 3 or the like at appropriate intervals, and as a result, the part of the patient's back that is being compressed changes from time to time, and therefore is not compressed for a long period of time. This prevents blood congestion and prevents pressure ulcers.

In the above embodiment, the crank handle 3 serving as the drive source is provided on the footboard 4 side, but it may also be provided on the headboard side or on the side of the bed 1. In addition, as a driving source,
A motor may also be applied.

Further, the common drive shaft 9 for simultaneously moving the lower portions of the respective supports 5 in the longitudinal direction of the bed frame 6 may have an appropriate structure other than the screw shaft described above.

Note that when the rod-shaped supports 5 rotate about their intermediate portions 10, their lower portions move slightly in the vertical direction, but this movement is caused by the drive shaft 9.
can be absorbed by making it movable by an appropriate mechanism.

(Effects of the invention) As described above, the present invention has a plurality of strip-like divided beds arranged in the longitudinal direction of the bed, and the longitudinal direction of the bed when the rod-shaped supports protruding from the bottom of the divided beds are moved in parallel. By swinging, the device can be tilted at a predetermined angle in alternate directions, so the portion that supports the body weight of a supine patient or the like can be changed. This prevents a portion of the patient's back from becoming congested over a long period of time due to pressure, and therefore, bedsores can be prevented.

In addition, because of the above configuration, the force required for driving is small, so it can be operated manually without difficulty, and the configuration can be simplified, making it easy to increase the number of divided beds. Can be configured.
