Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a bed for preventing bedsores for bedridden patients, and the bed is equipped with a number of rollers whose positions change in the horizontal direction on the bed to receive the weight of the patient. It is an object of the present invention to make it possible to efficiently prevent bedsores by changing the pressure point on the body by changing the position of the roller.

The present invention will be described below based on drawings showing an example of implementation.

In the figure, reference numeral 1 denotes a stand placed on the bed frame 2, which is shaped like a box with an opening at the top. Inside the box 1, there is a ■-shaped frame 3 that is long in the longitudinal direction of the bed 1. A large number of them are arranged horizontally with gaps in the width direction.

The mouth-like frame 3 is supported near both longitudinal ends thereof by common rollers 4, 4 which are rotatable around a lower horizontal axis.

5... are rollers that are rotatably supported in each frame 3 at equal intervals in the length direction of the frame 3 around a horizontal axis, and the rollers 5 and 5 of the adjacent frames 3, 3 are
... are provided with their positions shifted from front to back.

Further, the upper side of each roller 5 protrudes from the frame 3 and is located at the upper end opening 1a of the box-shaped base 1.

6 is a rod provided near both lengthwise ends of the frame 3 on the lower side in order to connect every other frame 3. ... are combined into one every other one.

Reference numerals 7 and 7 designate elemental bodies such as wires that connect two adjacent frames 3 and 3 located in the center of the large number of frames 3 to each other at both ends in the length direction, and each elemental body 7 is hung in a U-shape on a pulley 8 which is rotatably supported around a vertical axis 9 at both ends of the box 1.

Reference numeral 10 denotes a motor installed in the box molding 1 to reciprocate forward and reverse rotation of one pulley 8 at one end of the box molding 1.The rotation shaft of this motor 10 is oriented in the vertical direction, and the motor 10 is attached to this rotation shaft. Gear 11 and the one pulley 8
and a gear 12 mounted coaxially with each other, so that the one pulley 8 is rotated by rotation of the motor 10.

At this time, when one of the pulleys 8 is rotated by the motor 10, the element 7 hung on the pulley 8 moves in the rotation direction of the pulley 8, and the adjacent frames 3... 4.It is designed to slide horizontally on the top.

Although not shown in the drawing, every other frame 3.
. . is moved in one direction by the pulley 8 and the cable-shaped body 7, and then a limit switch or the like is provided to reversely rotate the motor 10 so that the motor 10 is moved in the opposite direction.

13 is a canvas that covers the box deposit 1, 14 is a mat placed on the canvas 13, and 15 is a sheet that covers the mat 14, on which the sick person sleeps.

Therefore, the patient's weight is transferred to the frame 3 through the mat 14.
It is received by the roller 5 inside...

Therefore, since the frames 3... move back and forth on the rollers 4, 4 so that the adjacent frames 3, 3 are in opposite directions, the position of the rollers 5... changes, and the pressure point on the body changes. Prevent bedsores.

If the adjacent frames 3, 3 are configured to move in opposite directions, the rollers 5 will not be biased towards one end of the bed, and can stably receive the weight of the bed. .

In the above embodiment, the rollers 5 and 5 of the adjacent frames 3, 3
... are provided by shifting their positions back and forth, but they do not need to be shifted.

By the way, the inside of the box 13 is made airtight by the canvas 13, and a large number of small holes are provided in the campus 13 so that air at an appropriate temperature and humidity is sent from inside the box 13 to the mat 14 side through the small holes of the canvas 13. You can also do it.

The bed for preventing bedsores of the present invention can be implemented as described above, and is equipped with a large number of rollers whose positions change in the horizontal direction so that the weight is received on these rollers, and the pressure on the body is reduced by changing the position of the rollers. Since the location is changed, pressure sores can be prevented efficiently.

In particular, according to the present invention, since adjacent roller support frames alternately reciprocate in opposite directions, blood is not constantly suppressed in one direction, but rather has the effect of mussing the pressing part. It has the effect of increasing blood flow more than in other areas, and has a remarkable effect on preventing blood circulation disorders and, by extension, bedsores.

Claims (1)

[Claims] 1. A large number of roller support frames, which are long in the front and back directions of the box-shaped base, are arranged side by side in a box molding with an opening at the top so that they can be moved in the front and rear directions, and each roller support frame has a frame that protrudes from the top end of the roller support frame. For preventing bedsores, the weight bearing is configured such that rollers are rotatably provided around a horizontal axis at appropriate intervals along the length of the frame, and adjacent frames are alternately reciprocated in opposite directions. bed.
