Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a bedsore prevention bed.

[Conventional technology]

A so-called bedridden patient who has a long-term medical treatment cannot move his / her body by himself, so that the blood circulation of the skin in contact with the bed is deteriorated and bed sores occur.

In order to prevent such bed sores, generally, a method of constantly moving the weight supporting portion of the bedridden patient, avoiding pressure at the same position for a long time, and improving blood circulation in the skin is used. JP-A-53-83394, JP-B-56-13943, JP-A-63-197458 and the like disclose techniques relating to beds capable of preventing bed slip.

For example, in a bedsore prevention bed (hereinafter referred to as a bed) disclosed in Japanese Patent Laid-Open No. 63-1974458, fulcrums serving as weight support portions work alternately so that a portion where the bed and the body come into contact can be arbitrarily changed. However, those disclosed in other publications are also based on almost the same technical idea, and all of them are intended to prevent bed slip by up and down operation.

[Problems to be solved by the device]

All of the beds described above are intended to prevent bed sores by simply moving up and down, but the cause of bed sores is that the skin of the body is pressed for a long time and blood circulation deteriorates.
Since a bed sore is generated, only the up and down operation can obtain a repeated action of pressing and releasing a certain part of the body, so that the effect of preventing the bed sore is small.

It is an object of the present invention to provide a bed capable of significantly reducing the time for compressing the body and having the so-called rubbing effect.

[Means for Solving the Problems]

The main structure of the present invention taken to eliminate the above-mentioned problems is a main body frame provided with a plurality of weight supporting first frames which are parallel to each other and arranged in a plane. A plurality of second frames for supporting the weight, which are provided at positions where they do not interfere with each other with the first frame of the body frame and are located in a plane formed by the first frame when not in operation, are supported by the support frame. The movable frame and the supporting frame are swingably supported at their four corners by a mounting frame that is integral with the main body frame,
A tilting means capable of tilting the moving frame three-dimensionally with respect to the main body frame; and a driving means for actuating the tilting means in a staggered manner.
Another feature is that tilting means for tilting the main body frame is provided, and the moving means is a cylinder and the tilting means is a cylinder. .

[Action]

The bed of the present invention includes a main body frame, a moving frame,
The moving frame includes moving means for moving the moving frame relative to the main body frame, and the moving frame can be moved three-dimensionally at a position where the moving frame does not interfere with the main body frame.

As described above, since the moving frame can be arbitrarily moved in three dimensions, it is possible to reduce the compression time at any part of the body and improve the circulation of blood in the skin. You can

In particular, the bed according to the present invention is not only subjected to vertical movements, but is also subjected to movements in which a force obliquely acts on the skin of the body such as forward and backward and left and right tilts. By this, a force along the skin of the body is generated, an action of stretching the skin is generated, and a so-called rubbing effect is obtained.

And, for example, the time difference operation of three basic movements up and down, front and back, and left and right can be easily implemented by computer control.

Furthermore, since the tilting motion of the main body frame can be added to the motion of the moving frame, the effect can be further improved.
