Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a body posture change assisting device that assists a person lying on a bed to change his/her body posture such as turning over by himself or raising his/her upper body.

Beds used by the physically handicapped, the elderly, the sick, and the like are provided with side rails to prevent the users themselves and their futons from falling. Such side rails are also used for changing the user's posture such as turning over, lying on his back, lying on his side, and standing up.
However, users who have paralysis or pain due to disabilities, medical conditions, surgery, etc. may not be able to use the side fences or reach the side fences themselves because their range of motion and activity is limited. Therefore, there is a problem that posture change cannot be easily performed.
In such a case, it is necessary to assist in changing the position by a medical person, a caregiver, or a family member. Such a situation causes mental and physical pain for those who cannot change their posture by themselves.
In addition, if the patient remains in the same position for a long time without changing his or her posture, there is a risk that blood flow failure due to body pressure may lead to pressure ulcers, nerve compression, and physical injury. Such a situation causes further pain and discomfort in the body, and is a major factor in more serious mental and physical pain.

With a little ingenuity and assistance, you can make the most of your own strength and change your posture. It protects human dignity and leads to improvement of self-healing ability. In addition, since the patient himself/herself can take care of changing the patient's position, medical staff can concentrate on their own work, and the burden on caregivers and family members can be greatly reduced.

A body posture changing aid 1000 according to an embodiment of the present invention is a body posture changing aid that assists a person lying on a bed 900 to change their body such as turning over and raising the upper body by themselves. ,
A fixing member 100 fixed to a side fence 910 of a bed 900, a string member 200 connected to the fixing member 100, and a grip portion 300 provided at the tip of the string member 200 are provided. is set to a length that a person lying on the bed 900 can reach the grip part 300 by reaching out.

The bed 900 is provided with a side rail 910 for preventing the user, such as a physically handicapped person or the elderly, and the futon from falling. This side fence 910 is provided on the lower body side of the user mainly to prevent the futon from falling.
As shown in FIG. 5, the side fence 910 consists of a rectangular main frame 911 with rounded corners, and a pair of vertical beams 912 formed by connecting the upper and lower sides of the main frame 911 and protruding downward. , and a horizontal beam 913 that spans between the vertical beams 912 are integrally formed.
A lower end of the vertical bar 911 is connected to the frame 920 of the bed 900 .

The fixing member 100 that constitutes the body posture changing aid 1000 has a plurality of (four in the figure) laminated substantially belt-shaped hook-and-loop fasteners 110A to 110D.
The fixing member 100 is configured by stacking four hook-and-loop fasteners 110A to 110D of the same size so as to overlap each other, and sewing and connecting the substantially central portions thereof. In addition, in the drawings, the sewn portions are indicated by x marks.
The connection of the string member 200 to the fixing member 100 will be described later.
Needless to say, the fixing member 100 is not limited to the four laminated hook-and-loop fasteners 110A to 110D, and may be two hook-and-loop fasteners or five or more hook-and-loop fasteners. Each hook-and-loop fastener 110A to 110D has countless loops formed on one surface and countless hook-shaped hooks formed on the other surface.

The fixing member 100 is fixed to the vertical beam 912 above the intersection of the vertical beam 912 and the horizontal beam 913 of the side fence 910 . That is, the side fence 910 is used as a fixed portion.
The innermost hook-and-loop fastener 110A is wound around the vertical bar 912, and the second hook-and-loop fastener 110B is wound on the innermost hook-and-loop fastener 110A. Wrap it around. At this time, if the right side of the innermost hook-and-loop fastener 110A is wound directly around the vertical bar 912 and the left side is wrapped around the upper side of the hook-and-loop fastener 110A, the left side of the second hook-and-loop fastener 110B is the innermost hook-and-loop fastener 110A. , and the right side is wound on the left side of the second hook-and-loop fastener 110B.
By alternately winding the hook-and-loop fasteners 110A to 110D in this manner, the fixing member 100 is more firmly fixed to the vertical beam 912. As shown in FIG.

The grip portion 300 is a ball-shaped member made of wood or the like that is comfortable to grip and has excellent strength, and has a diameter of 5 to 10 cm. A pair of parallel through holes 310 are formed in the grip portion 300 . The through hole 310 is a portion through which the string member 200 is passed.
As will be described later, both ends of the string member 200 are connected to the fixing member 100 to form a loop. Therefore, by passing the string member 200 through the pair of through holes 310, the grip portion 300 is connected to the string member 200. It will be.

On the other hand, the cord member 200 has, for example, a plurality of core materials inside and a skin covering the core materials. A so-called parachute cord having excellent strength is used, which is constructed by weaving fibers of
Both ends of the string member 200 are divided into four parts, each of which is sewn to the applying cloth in a state of being sandwiched between two applying cloths (not shown). That is, the string member 200 is connected to four sets of patch cloths. These four sets of patch cloths are sewn and connected to the four hook-and-loop fasteners 110A to 110D constituting the fixing member 100, respectively. Then, the four hook-and-loop fasteners 110A to 100D are sewn together at the central portion to be connected to the fixing member 100. As shown in FIG.

Since both ends of the string member 200 are connected to the fixing member 100, the string member 200 has a loop shape, and as described above, the looped string member 200 is passed through the through hole 310 of the grip portion 300 and connected. can do.

In addition, the string member 200 is set to have a length that a person lying on the bed 900 can reach the grip portion 300 by reaching out. Specifically, it is 20 to 80 cm. However, since the optimum length differs depending on the physique of the user, it is conceivable to enable the user to appropriately select from a plurality of types of string members 200 having different lengths.
The string member 200 is twisted between the fixing member 100 and the grip portion 300 by a knotting method called left-right knot (left-right knitting) in which, for example, two strings are alternately knotted. It has become.

The body posture changing aid 1000 configured as described above is used as follows.
First, the fixing member 100 is fixed to the side fence 910 . The fixing member 100 is fixed to the side fence 910 by alternately winding and laminating the four surface fasteners 110A to 110D constituting the fixing member 100, as described above.
Fixing the body posture changing aid 1000 to the side fence 910 is a simple work of winding four hook-and-loop fasteners 110A to 110D, so anyone can do it, and besides, it can be easily attached to the side fence 910 of the existing bed 900. can be fixed.

The grip part 300 is positioned so that the user lying on the bed 900 can reach the grip part 300, so that the grip part 300 can be gripped while lying down.
The user pulls the body posture changing assisting tool 1000 with force while gripping the grip part 300, and rolls over or raises the upper body.
Since the body posture changing aid 1000 is firmly fixed to the side fence 910 by the fixing member 100, it will not come off with a force that changes the posture of the body.
If the user can change the posture of the body by himself/herself, it is useful for maintaining a good position of the limbs and correcting the posture. In particular, it is a useful exercise that can be done without overdoing it for the elderly, the physically handicapped, and the user who is undergoing rehabilitation after surgery.

In the above description, the grip part 300 is a ball-shaped member having a pair of parallel through holes 310, but the number of through holes 310 may be one as shown in FIG. When there is one through-hole 310 , the string member 200 is not loop-shaped, and connects with a fastening member 320 larger than the through-hole 310 at the tip of the through-hole 310 . Also, instead of the fastening member 320 , the end of the string member 200 may be a knot ball larger than the through hole 310 .
Also, the grip part 300 may be a ring-shaped member instead of a ball-shaped member.

In the above description, the fixing member 100 is formed by laminating four hook-and-loop fasteners 110 to 110D, but the present invention is not limited to this.
For example, the fixing member 100 may be a carabiner (a metal ring with a part (gate) that can be opened and closed) or the like. However, since the side rails 910 are often made of metal, if the fixing member 100 is a metal carabiner, there is a problem that contact noise will be heard. should be
Alternatively, the fixing member 100 may be composed of a strong nylon belt and a pair of D-rings connected thereto.

Also, the string member 200 may be a strong nylon belt instead of a parachute cord. In this case, the through holes 310 of the gripping portion 300 are a pair of flat plate-shaped holes through which the nylon belt can pass, and the nylon belt penetrates the flat plate-shaped holes in a loop shape, thereby connecting the gripping portion 300 to the string member 200. to connect. Of course, it goes without saying that the string member 200 may be made of ordinary natural fibers such as cotton.

Furthermore, in the above-described embodiment, the body posture changing aid 1000 is fixed to the side rail 910 of the bed 900, but in the case of the bed 900 without the side rail 910 as shown in FIG. The body posture changing aid 1000 may be attached by directly wrapping and fixing the member 100 around the frame 920 of the bed 900 .
Needless to say, the body posture changing aid 1000 may be fixed to the frame 920 even in the bed 900 provided with the side rails 910 .

Further, as shown in FIG. 10, a protrusion 951 is formed on a side surface 950 of a bed 900, and the fixing member 100 of the body posture changing aid 1000 is wrapped around the protrusion 951 as a part to be fixed. It can also be fixed. At the tip of the protrusion 951, a slip-off prevention member 952 is formed to be thicker than the portion around which the fixing member 100 is wound so that the wrapped fixing member 100 does not come off inadvertently.

Furthermore, as shown in FIG. 11, an opening 953 is formed in the side surface 950 of the bed 900, and the body posture changing aid 1000 can be fixed by winding the fixing member 100 around the opening 953 as a portion to be fixed. .
Positioning the opening 953 near the chest of the lying user is most convenient for changing the user's posture.

Further, in the case of the bed 900 in which the projection 951 and the opening 953 on the side surface 950 as described above are not formed, it is possible to use an auxiliary member 960 as shown in FIG. 12 as the fixed portion.
This auxiliary member 960 has a substantially concave-shaped main body 961 that sandwiches the side surface 950 of the bed 900 and a male screw portion 962 that is screwed into this main body 961 . The main body 961 is formed in a substantially concave shape as a whole by connecting a pair of parallel plate members 961A with a connecting member 961B.
The interval between the pair of plate members 961A is set larger than the thickness dimension of the side surface 950 of the standard bed 900. As shown in FIG. A female threaded portion (not shown) corresponding to the male threaded portion 962 is formed on one plate member 961A. The auxiliary member 960 is fixed to the side surface 950 of the bed 900 by screwing the male screw portion 962 into the female screw portion while the side surface 950 of the bed 900 is sandwiched between the pair of plate members 961A.
The male threaded portion 962 protrudes to a length that allows the fixing member 100 to be wound even when the main body 961 is fixed to the side surface 950 of the bed 900 . The body posture changing aid 1000 is fixed by winding the fixing member 100 around the projecting portion.
The externally threaded portion 962 of the auxiliary member 960 fixes the holding member 960 itself to the bed 900, and also serves as a portion to be fixed, around which the fixing member 100 is wound.
This auxiliary member 960 is also positioned near the chest of the lying user. However, it goes without saying that the position of this auxiliary member 960 can be changed according to the physique and preference of the user.

Instead of the bed 900, when using a normal futon or mattress (hereinafter referred to as a futon, etc. 800) that is directly laid on the tatami mat, the side rails 910, the frame 920, the side surfaces 950, and the auxiliary Member 960 cannot be used.
In this case, as shown in FIG. 8, a base plate 810 installed under a mattress 800 or the like is used. A protruding member 820 is provided on the side edge of the base plate 810 , and the fixing member 100 is fixed to the protruding member 820 . This protruding member 820 is set so as to be positioned approximately at the user's chest.
In order to minimize the risk, use materials that change position and shape, such as ropes, instead of materials that do not change position or shape, such as metal.

Further, instead of providing the projecting member 820 on the base plate 810, it is possible to form an opening in the side edge of the base plate 810 and wind the fixing member 100 of the body posture changing aid 1000 around this opening. . In this case, since there is no protruding part such as the protruding member 820, it can be used more safely.
The base plate 810 is preferably installed at a position where the weight of the user lying on the mattress or the like 800 is applied most, that is, between the waist and the chest. In this case, most of the user's weight is applied to the base plate 810, so that the base plate 810 and thus the body posture changing aid 1000 are less likely to move during use, which is safe.

Further, as shown in FIG. 9, it is also possible to form a projecting piece 830 formed on the side edge of a mattress 800 and use this projecting piece 830 as a fixed portion.
The protruding piece 830 is a tongue-like member firmly sewn to the side edge of the mattress 800, and has an opening 831 formed therein. The fixing member 100 is connected using this opening 831 .
It should be noted that the protruding piece 830 does not need to be substantially annular as shown in FIG. Just do it.
This protruding piece 830 is also positioned near the chest of the lying user.

In the above-described embodiment, the grip portion 300 is a ball-shaped member having a pair of parallel through holes 310. However, the through holes 310 are twisted as shown in FIG. It is needless to say that the crossing may be such that the crossings are made in the shape of an X, as shown in FIG. 13(B).

Furthermore, in the above-described embodiment, the grip part 300 is connected only to the tip of the string member 200, but as shown in FIG. may be provided. In this case, by providing a plurality of gripping portions 300, it is possible to appropriately deal with differences in user's posture and physique. It should be noted that the holding part 300 is kept in place by weaving or tying the string member 200 . Alternatively, the holding part 300 may be fixed with a fastener (not shown) so that the position does not shift.

Moreover, by connecting the grip part 300 only to the tip of the string member 300 and forming a loop 210 as shown in FIG. be able to respond. This loop 210 is kept in place by weaving or tying the string member 200 . Alternatively, the position of the loop member 210 may be prevented by fastening it with a fastener (not shown).

The gripping portion 300 may be a loop-shaped member as shown in FIG. 14(C) as well as a ball-shaped member as shown in FIGS. This loop-shaped 300 is not separate from the string member 200, but is formed by looping the end portion of the string member 200. As shown in FIG. If part of the string member 200 is used as the grip part 300 in this way, the number of constituent members can be further reduced, so that the cost of the body posture changing aid 1000 can be reduced.

Of course, a knotted ball formed by tying the string member 200 may be used instead of the plurality of gripping portions 300 and the loops 210 .

In the above-described embodiment, the body posture changing assisting device 1000 is configured by stacking four hook-and-loop fasteners 110A to 110D of the same size so as to overlap each other, and connecting them by sewing their approximate central portions. Was.
However, as shown in FIG. 15, it is also possible to configure the fixing member 100 by stacking four hook-and-loop fasteners 110A to 110D of the same size in a staggered manner so that only a portion of the fasteners overlap.

15, the hook-and-loop fastener 110A is on the left end of the drawing, the hook-and-loop fastener 110B is on the right end of the drawing, the hook-and-loop fastener 110C is on the left end of the drawing, and the hook-and-loop fastener 110D are connected with their right ends on the drawing being overlapped.
By laminating the hook-and-loop fasteners 110A to 110D so as to partially overlap each other in this way, the size of the hook-and-loop fasteners 110A to 110D can be reduced while the overall size can be reduced by stacking the hook-and-loop fasteners 110A to 110D so as to overlap each other. can be the same.

In addition, even if the hook-and-loop fasteners 110A to 110D are staggered and laminated, and even if they are stacked without being shifted, hook-shaped hooks or loops are formed only on one surface of each of the hook-and-loop fasteners 110A to 110D. , hook-like hooks formed on one side of each of the hook-and-loop fasteners 110A to 110D and loops formed on the other side.

The fixing member 100 is fixed to the fixed portion and cannot be easily removed.
It is sufficient if the fixing member 100 is completely fixed to the fixed part. , there is a risk of accidents such as the user falling.
In order to prevent such an accident, it is possible to provide a lock mechanism for maintaining the fixed state of the fixing member 100 to the fixed part so that the fixing member 100 fixed to the fixed part does not come off.
This lock mechanism includes general locks, such as a so-called padlock whose latch is opened by a special key, a so-called magnet lock whose latch can be locked and unlocked by a special key using a magnet, and a password. A dial lock that can be locked and unlocked by a latch is used. Note that the lock used for the lock mechanism is not limited to the one described above, and any common lock can be used.

For example, in the case of the fixing member 100 using four hook-and-loop fasteners 110A-110D, each hook-and-loop fastener 110A-110D is provided with an opening that matches when the hook-and-loop fasteners 110A-110D are fixed to the part to be fixed. By passing the hooks through all the openings at once, the hook-and-loop fasteners 110A to 110D do not come off, that is, the fixing member 100 does not come off from the fixed part.
When the fixing member 100 is to be removed from the part to be fixed, it can be easily removed by releasing the locking mechanism and then peeling off the four hook-and-loop fasteners 110A to 110D.

This locking mechanism does not come off when the fixing member 100 must not come off, and can be easily removed when it is removed, so that the body posture changing aid can be used more safely. is now possible.
