Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bedsore prevention bed used in homes, nursing homes, hospitals, etc., by bedridden elderly people, long-term caregivers, etc., who cannot roll over on their own.

[0002]

BACKGROUND OF THE INVENTION Many bedridden people suffer from so-called bedsores. Bedsores are caused by compression of a particular part of the body (particularly the heavier buttocks) for a long time, resulting in poor circulation and necrosis of the tissue in that part. To prevent bedsores, caregivers must turn a bedridden person at least once every four hours at night. However, a bedridden person who cannot freely turn over on his own will usually not be able to spend a comfortable time turning around once every four hours. In particular, the mental and physical distress caused by not being able to turn over on their own is difficult for a healthy person to understand, but is very large. On the other hand, the work of turning over a bedridden person is a heavy burden on the caregiver, since the work must be performed at regular intervals of day and night.

Under such circumstances, various bedsore prevention beds for bedridden persons have recently been proposed. In Japanese Utility Model Publication No. 5-30434, a plurality of strip-shaped divided floors are arranged in the longitudinal direction of the bed to form a floor portion, and each divided floor keeps the floor surface parallel to each other. A bed configured to be swingable in the longitudinal direction of the bed is described. Japanese Patent Application Laid-Open No. Hei 8-196576 discloses a bed having a floor on which a person can sleep and a base on which the floor is placed, wherein the floor is arranged in a plurality in a lateral direction of the bed. A bed is described, comprising a floor member, wherein the base body has a floor member driving means capable of rotating all or part of the floor member about the longitudinal direction of the bed as an axis. .

[0004]

In each of the techniques described in the above two publications, each of the plurality of floor members that divide the floor is configured to be rotatable. For this reason, by rotating the floor member, the contact point between the sleeping person and the floor of the bed can be appropriately changed, but the posture of the sleeping person is changed, that is, the person sleeping on the back is moved. You cannot turn over to the right or left. The present invention has been made in view of the above-described problems of the related art, and enables a sleeping person to turn over without using human power, and a contact point between a sleeping person and a bed floor varies in various ways. Another object of the present invention is to provide a bedsore prevention bed capable of preventing bedsores.

[0005]

A bed for preventing bedsores according to the present invention has a floor surface formed by arranging a plurality of floor surface members side by side. Each of the plurality of floor surface members is formed of a bed. The floor has a long upper surface shape that is cut by dividing the floor surface in a direction parallel to the longitudinal direction of the bed, and has a step of an arbitrary height with respect to an adjacent floor surface member. It is configured to be able to move up and down (claim 1). As one embodiment of the bedsore prevention bed of the present invention, a bed provided with a manually operated floor surface control device so that each of the plurality of floor surface members can be freely raised and lowered independently of each other. (Claim 2). As another embodiment of the bedsore prevention bed of the present invention, the floor formed by the plurality of floor members can be automatically and sequentially changed to various pre-programmed irregularities. In addition, an apparatus having a floor control device for controlling the elevation of the plurality of floor members can be cited (claim 3).

[0006]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to the drawings. FIG. 1 is a perspective view showing an example of a bed for preventing bedsores of the present invention, FIG. 2 is a plan view thereof, FIG. 3 is a cross-sectional view in a lateral direction of the bed showing an example of a height adjusting mechanism of a floor member, FIG. 4 is a cross-sectional view in the longitudinal direction of the bed showing an example of a height adjusting mechanism of the floor member, and FIG. 5 is a cross-sectional view in the longitudinal direction of the bed showing another example of the height adjusting mechanism of the floor member.

In FIG. 1, bedsores 1 for preventing bedsores have a pair of frame plates 2 facing each other, a perforated horizontal plate 3 provided between the frame plates 2, and six beds located above the horizontal plate 3. Floor members 4 and 6
Floor control device 5 for controlling the elevation of individual floor members 4
Are the main components. Here, the floor control device 5 includes a central control device 6, an electric motor 7, and the like.

The floor member 4 has a long upper surface obtained by cutting the floor surface (the surface on which a person sleeps) of the bed 1 for preventing bedsores in a direction parallel to the longitudinal direction of the bed. A slight gap may be formed between the adjacent floor members 4 so as not to impair the sleeping comfort of a sleeping person, or
The floor members 4 may be in contact with each other as long as the floor members 4 are slidable in the vertical direction. Although not shown, if a mat, a mattress or the like is laid on the floor member 4 and further covered with sheets, it can be used for actual use.

The vertical section of the floor member 4 (transverse direction of the bed 1 for preventing bedsores) is usually formed in a rectangular shape (see FIG. 3), but may have another shape. For example, in order to prevent bedridden persons from feeling uncomfortable due to a step formed between adjacent floor members 4, both edges of the upper surface of the floor member are cut out round or diagonally. A part may be formed. In particular, when the material of the floor member 4 is firm, it is preferable to form a rounded edge.

When a material having an appropriate elasticity is used as the material of the floor member 4, sheets may be directly placed on the floor member 4. As the material having elasticity, besides a material usually used as a material for a mattress (such as cotton), a material in which a fluid such as water is filled in a bag made of a synthetic resin (a so-called water bed) may be used. When the sheets are placed directly on the floor member 4, the sheets may be ordinary sheets covering the entire floor surface, or may be attached to each floor member 4. In a case where the sheet is attached to each floor member, it is preferable that the sheets can be attached to the upper surface and both side surfaces of the floor member.

As the number of floor members 4 increases, the unevenness of the floor surface can be made smoother, but the number of height adjustment mechanisms provided for each floor member 4 increases, and The whole surface control device becomes large and complicated. Therefore, the number of floor members 4 is generally 4 to 10, preferably 6 to 8. The inclination of the floor surface can be any angle. However, the inclination angle (an angle formed by a straight line connecting the center point of the upper surface of the floor member and the horizontal plane) is locally set to about 20 degrees at maximum so as not to give a feeling of anxiety to a sleeping person. Is preferred. The time required for the floor in the horizontal state to change to a floor having a slope of 20 degrees is preferably, for example, about 1 to 3 minutes. As a result, the sleeping person gradually changes his or her posture, does not put a burden on the body, and does not cause a feeling of psychological anxiety.

A support plate 8 as shown in FIGS. 3 and 4 is fixed to the lower surface of the floor member 4 at a location indicated by a dotted line in FIG. Rods 9 are fixed to the lower surfaces of these support plates 8. The rod 9 is inserted into the through hole of the horizontal plate 3 and hangs downward, and the horizontal plate 10
Is fixed. In addition, the horizontal plate 3 fixes the frame plate 2 and determines the position of the floor member 4.

The horizontal plate 10 has an appropriate thickness, and has a through hole formed in a vertical direction and having an inner peripheral surface threaded. A rod-shaped slide screw 11 whose outer peripheral surface is threaded is screwed into the through hole from below. The slide screw 11 is connected to a rotation shaft of the electric motor 7 disposed below, and can rotate by a desired number of rotations as needed. Similarly, another electric motor 7 and the like are provided for the other support plate 8 of the same floor member 4. The rotating shafts of the pair (two) of electric motors 7 provided for one floor member 4 are controlled by the central control device 6 so as to make the same rotation. Thereby, the floor member 4 is moved up and down and adjusted to an arbitrary height while always keeping its upper surface horizontal.

A total of 12 (6 × 2) motors 7 arranged for each floor member 4 are controlled by a central controller 6. The floor members 4 can be moved up and down to different heights according to instructions from the central control device 6. In this specification, a floor control device refers to the entire means for controlling the height of a plurality of floor members. In FIG. 1, the floor control device 5 includes a central control device 6, a plurality of electric motors 7 connected to the central control device 6, and a slide screw 11 connected to each electric motor 7.

The floor control device 5 has various modes. One embodiment of the floor control device 5 includes a plurality of floor members 4.
Are manually operated so that each of them has an arbitrary height independently of each other. In this case, it is desirable to provide a portable remote control device for instructing the central control device 6. Thereby, the bedridden person or caregiver can adjust the height of each of the floor members 4 by simply operating a switch on the remote control device, and can adjust the height of the floor 1 of the bedsore prevention bed 1 to a desired level. Can be inclined. In a welfare facility or the like that takes care of a large number of bedridden elderly people, a plurality of beds may be centrally managed in one place, and one staff member may remotely control the operation of each bed.

Another mode of the floor controller 5 is to control the plurality of floor members 4 as a whole. That is, the irregularities on the floor surface are programmed in advance so that the irregularities on the floor surface change continuously, and only when the bedridden person or caregiver turns on the switch first, the irregularities on the floor surface automatically and periodically change. It is changing. For example, if the three postures of turning to the right, turning on the back, and turning to the left are programmed so that they can be alternately taken periodically (for example, every 30 minutes to 3 hours), a bedridden person can be programmed. ,
It can be turned over at regular intervals without relying on human power.

At this time, as shown in FIG. 3, in order to prevent the beds from falling off the beds 1 for preventing bedsores, the floor members 4 at both ends of the floor are smaller than the inner floor members 4 adjacent thereto. It is desirable to keep the program high. It is convenient for the control of the floor member 4 to make it possible to appropriately change only the period of the change in the case where the change in the uneven shape of the floor is programmed in advance. Thereby,
It is possible to control the posture of the bedridden person every hour during the day and every three hours at night, or to shorten or lengthen the period of change according to the needs of the sleeping person. Will be possible.

An arbitrary mechanism other than the one shown in FIG. 4 can be adopted as the elevation mechanism of the floor member 4. For example, as shown in FIG. 5, a link mechanism may be used. In FIG. 5, an electric link device 13 is disposed on the lower surface of the floor member 4 via a metal support plate 12. The link device 13 moves the connecting portion 17 toward or away from the connecting portion 16 by rotating the slide screw 15 connected to the shaft of the electric motor 14, and as a result, the distance between the connecting portion 18 and the connecting portion 19. And the height of the floor member 4 can be changed.

[0019]

According to the beds for bedsore prevention of the present invention,
Bedridden people can turn over at short intervals without the assistance of a caregiver. In addition, in the case where the height of each floor member can be arbitrarily adjusted by using a portable control device or the like, the bedridden person himself / herself can use the portable control device only to operate the buttons of the bed. A desired inclination (irregular shape) can be formed on the floor surface, and a desired posture can be taken on the bed. If the floor surface of the bedsore prevention bed is configured to automatically change to various pre-programmed irregularities, the bedridden person or caregiver first switches the floor control device. It is only necessary to insert the bed, and there is no need to perform any subsequent operations, so that the trouble of adjusting the shape of the floor of the bed is released.

As described above, by using the bedsore-preventing bed of the present invention, the bedridden person's posture can be changed at any time or periodically. Can be prevented and the physical and mental distress of a bedridden person can be significantly reduced. In the future aging society, the number of bedridden elderly people is expected to increase. Along with this, there is a strong demand for a recuperation bed that can be comfortably used even by bedridden elderly people. The bedsores prevention bed of the present invention meets such social needs and is extremely useful.
