Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention makes it possible to keep a bedridden elderly person or the like in a sitting position in the care of a home, a hospital or a welfare facility, and a bedridden or incapacitated person from a bed. The present invention relates to a floor-traveling type elevator which can be moved to another place and excreted, eaten and rested by a disabled person while sitting.

[0002]

2. Description of the Related Art With the aging of Japan, the number of persons with disabilities due to aging is increasing rapidly, and the number of nuclear families is increasing. . In other words, most of the elderly who care for the elderly at home are spouses, and therefore the caregivers are also elderly. However, the nursing power required for this is more labor than I imagined, and it is often the case that elderly people with disabilities become bedridden because of tiredness of nursing care.
As a policy of Japan, the Gold Plan has been launched, and welfare policies are being implemented in various aspects, and even at home, they are working hard to “from on bed to on chair”. However, there are few devices that reduce the caregiving ability at home, and as mentioned above, due to the difficulty of nursing care as a result, elderly people with disabilities are made to be "sleep-only" rather than "sleep-only." It is in the situation of diaper attachment ”. As a result, the person with a disability has no motivation to maintain / recover the remaining function, and the mental status has deteriorated. On the contrary, maintaining the above-mentioned on-chair, that is, sitting posture, improves the ability to swallow when eating and drinking (makes it difficult), restores physical function by improving muscle strength of the body, and independence such as eating and excretion due to this recovery. , It will reduce the caregiver of caregivers and improve their motivation to live. When moving to another chair or wheelchair to hold this sitting position, if you try to do it without using equipment or equipment, the caregiver will hug and transfer the disabled person. It was quite difficult, and in some cases the caregiver often hurt his back. Therefore, in home-based nursing, bedridden elderly people with disabilities can be kept in a sitting position, and bedridden / ambulatory people are moved from the bed to other places, and the disabled people excrete themselves, eat, and rest while sitting. It is necessary to provide an elevator that can reduce the nursing power at this time, and also in hospitals / welfare facilities, such an elevator that can reduce the nursing power of nurses, nurses, caregivers, etc. Was needed.

Conventionally, there are roughly three types of elevators of this kind for moving a bedridden or disabled person who cannot walk from a bed. 1) One is to install a rail on the ceiling, and a lift attached to this rail and a sling sheet, which is a sewing product that holds the entire body, to lift the handicapped person and move along the rail (ceiling traveling lift). Is. 2) The second one has wheels so that it can run on the floor, can be inserted into the space under the bed, and has a frame equipped with wheels, an arm part formed above the person with a disability on the bed, and this arm part is installed. It is a device that lifts a handicapped person with a lift and a sling sheet similar to the above, and travels by moving the entire elevator with wheels. (Lift type floor traveling lift) 3) The third has a wheel that can travel on the floor, and a frame that can be inserted into the space under the bed and has wheels,
Hold the knee, waist, and back of the disabled person in a sitting position and lean forward or lift upward. (In this case, the knees are elastic knee pads, and the waist and back are fixed with sewn products.) It is a device that travels by moving the entire elevator with wheels (forward tilting-type traveling lift). 4) In addition, there is a gudget bed which can be backed up as a conventional device only for keeping the sitting position on the bed.

[0004]

Generally speaking, conventional elevators can be said to have a transfer purpose as their main purpose only, and therefore, to hold a sitting position other than on the bed, other chairs or wheelchairs can be used. When transferring, first attach the sling seat that holds the body on the bed (pass the belt or seat under the waist or back and fix the belt to the elevator), and then remove the sling seat on the chair after moving. Two steps of work were required (remove the belt from the elevator and pull out the seat and belt from under the waist). Also, when returning to the bed, the same work is required and two steps are required. Therefore,
There has been a problem that the work using the conventional elevator has a considerable burden on the caregiver. Moreover, since the conventional sling sheet is made of soft sewing products,
While it has the advantage that the thighs, waist, back, etc. fit into the sewn product when it is lifted up, and that it can be stress-free in a curved state, that is, in a hammock state, it can also be suppressed from the side, so the disabled person can There was no freedom to move it, and it had the drawback that it could not stay in this state for a long time.

Regarding the above-mentioned concrete three types of elevators, 1) In the "ceiling traveling lift", a large amount of equipment cost is required to install the rail on the ceiling, and the moving position is limited. There was a problem that it would end up. 2) In the "lifting floor traveling lift", since the equipment becomes considerably large and heavy, it requires a considerable amount of power to move and travel, and the burden on the caregiver becomes large.
Since such a device is large, it requires a large space and is unsuitable for housing in Japan. 3) In the “forward tilt suspension type traveling lift”, since the weight of the disabled is supported by the knees, hips and back, the burden of hitting the knees is large,
There was a problem that people with disabilities hurt. 4) In the "gadget bed", it is advantageous to consider sitting alone to wake up from the sleeping state.
For excretion, diapers, urinals, and toilets are required, and it is difficult to excrete in portable toilets and home toilets for more independence in gadget beds, and in rooms other than bedrooms for mental improvement (improvement of life). You cannot move to (living room, dining room, etc.) and spend time in the same room with your family. As described above, because there is no suitable device that can reduce the caregiving ability, not only the disabled person but also the caregiver are exhausted, and therefore the entire family is exhausted and worthwhile for one elderly person with disabilities. There was a big social problem that it ended up.

[0006] Therefore, the object of the present invention is to: -Structure that can easily hold the sitting position.・ Make it easy to move (lift) from the bed. -Reduce the caregiving ability by reducing the sling sheet attachment / detachment process. -Continue to use the device by reducing the caregiver of elderly caregivers.・ Persons with disabilities should be able to cope with excretion of heavy work even in nursing as much as possible. -The elevator itself should be able to run on the floor while maintaining a sitting position without the burden on the disabled.・ Make the equipment compact according to the housing situation in Japan. It is in.

[0007]

In order to solve the above problems, according to the present invention, there is provided a floor traveling type elevator, two rear wheel arms each having a moving wheel and extending rearward, and each of the rear wheels. A lower frame portion provided with a lower sliding frame extending upward from the arm for use; an upper sliding frame provided so as to be able to move up and down relative to the lower sliding frame; An upper frame portion having two sling arms attached thereto; a fixing means provided on the sling arm for detachably fixing a seat on which a person sits, to the sling arm; and the sliding upper portion. And an elevating means for elevating and lowering the frame and holding the height thereof. That is, the elevator body is a floor-running type using caster wheels, the upper frame is provided with two arms so that a person with a disability can hold both sides in a sitting state, and a sling seat is detachably attached to each arm. A total of four buckle fixing parts, two at the front and the rear, are formed, and a table for people with disabilities to eat and a handle for moving the elevator for helpers are integrally configured, and the entire upper frame part is the lower frame. It is slidable up and down with respect to the part.

The sling seat for holding the sitting position is
The back, the belt with a buckle for hanging, and the back holding belt that holds the angle of the seat back are integrally formed, and the seat and the back sit on a surface that is in contact with the body and a rigid member that does not bend even if a load is applied. It is made of a soft material for easy handling, and the seat and back are bent at an angle. For excretion, hold the thigh so that it does not fall downward,
If you can hold the entire torso on the front side, you can lean forward slightly, but you can still hold your weight.Therefore, install a detachable thigh holder on the upper frame and hold the entire torso around it. By using the body holding sewn product with fixing metal fittings at both ends, by fixing both ends of the body sewn product to the handles on the front side of the upper frame, the lower body can be taken off and excretion is prevented. It will be possible. This thigh holder and torso holding sewing product can be mounted while sitting on the sitting sling seat, and the body can be held for excretion even if the sitting sling seat is removed after mounting. It is a thing.

[0009]

[Operation] With the above configuration, the procedure for putting an elderly person with a disability sleeping on the bed on the sling sheet is as follows.
It looks like this: 1) First, turn the handicapped person sideways and lay it flat with the sling sheet for holding the sitting position open at the position where he / she was lying on his back. 2) Return the disabled person to his or her back and put it on the sling seat for sitting. 3) The caregiver lifts the back of the sling seat and the back of the handicapped person with one hand, rotates 90 degrees with the sling seat while pushing the foot with the other hand, and sits down on the edge of the bed. (At this time, the seat part is hard in the lateral direction, so it is easy to rotate.) 4) Fit the buckle of the back holding belt provided on the sling seat to the left and right sides. (In this state, the sitting position holding sling seat has a truss structure when viewed from the side, and it is possible to keep the bed end sitting position by just leaning on the back.) 5) The elevator body is moved, and the disabled person moves the bed end sitting position. Insert the elevator body from the front side and lock the caster wheels by rotation. 6) Lower the entire upper frame part and set the hanging belt at a position where it is easy to attach. 7) Hanging belt 4 provided on the sling sheet
Insert the book buckle into the arm of the lifter body and fix it. 8) Raise the entire upper frame part to float the disabled person on the bed. 9) Hold the elevator handle and pull it out of the bed. 10) Adjust the height of the entire upper frame by sliding it up or down to the height desired by the disabled. 11) Move in the bedroom or move to a room other than the bedroom. With the above procedure, it is possible to hold a true sitting position with the tip of the knee lowered, which could not be obtained on the bed, and the side that holds the body on the seat and back without pressing the waist from the side. Since it is a soft material, it is possible to obtain a device that can hold a sitting position for a long time. Furthermore, the two arms that suspend the seat serve as armrests, so that a comfortable sitting position can be achieved.

Also, since the entire seat is suspended, even if the body is tilted to the left or right, the entire seat follows the balance, and the sitting comfort is quite good.
In other words, even for people with disabilities with hemiplegia, the balance of the seat is followed, the two arms that suspend the seat rest on the armrests, and the back holding belt receives the lateral load. You will be able to maintain a sitting position without burdening yourself. In addition, with the conventional sling seat, you can attach it when you put it on and remove it when you put it down on a chair.
Assistance work required for one step is reduced to one step, and the caregiver can be halved, making it possible for the caregiver to continue using the device for a long time.

The procedure for excretion is as follows. 1) While sitting on the sling seat for holding the sitting position, insert the thigh holders into the thigh holder fixing portion of the elevator body one by one. 2) Wrap the trunk of the handicapped person with the body-holding sewing product and attach the fixing hooks to the handle on both sides while tilting the handicapped person forward slightly. 3) Sequentially remove the buckle on the body of the sling seat for holding the sitting position, which was previously installed, and then remove the entire sling seat. 4) If you can move to a home toilet, go to a home toilet. Move to a portable toilet if it is difficult due to the housing environment. 5) Remove the lower body clothes to the thigh holder, lower the entire upper frame until it sits on the toilet, and excrete. You can excrete by the procedure. At this time, the posture of holding the handicapped person is not very effective for holding for a long time, but when excreting, it can sit on the toilet seat and only needs to be held for the time of moving and putting on and taking off clothes, so that excretion becomes independent (from diapers). Can be measured.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. The elevator main body 1 is as shown in FIG. 1.-The entire structure can lift a disabled person on a bed.
The lower frame 3 is inserted under the bed so that the strength and center of gravity are safe. The whole structure is U-shaped (where the U-shaped connecting rod side is the "front side", The open side is referred to as the "rear side".)-Wheels are provided on the lower frame portion 3 to enable floor running. Further, the wheels are caster wheels 4 which are four wheels with a sense of stability so that the elevator body 1 can be easily handled even in a small room. The rear wheel arm 5 of the lower frame part 3 has a low height so that it can be used in a narrow space under the bed, and the caster wheels 4 are also small in size, and the front wheels have running force and casters. Large caster wheels 4 are used for the advantage of rotation. Two sliding lower frames 6 are integrally provided on the front side of the lower frame portion 3 from both sides so as to allow the upper frame portion 2 to slide up and down.
The reason why the sliding lower frame 6 is two from both sides is to provide a space for placing a foot when sitting. Also, the inclination to the front side is low when the caregiver moves while holding the handle 11 so as to secure a foot space so that the foot does not hit the lower frame portion 3 of the elevator, and is low when moving up and down with a handicapped person placed. The center of gravity is slightly on the rear wheel side at the position, and the center of gravity is slightly on the front wheel side at a higher position. This is because the distance between the front and rear wheels (wheel base) is shortened so that it can be maneuvered more compactly. Has become. -The upper frame 2 is provided with sling arms 7 on both sides so that the sling seat can be held and seated by the handicapped person in a sitting state, and the table 9 where the handicapped person can eat etc. A handle 11 for moving the is integrally formed. -The sling arm 7 is provided with a buckle fixing part for suspending and fixing the sitting-position holding sling sheet, and a thigh holding part fixing part 10 is provided for dealing with excretion. A sliding upper frame 13 with a roller corresponding to the sliding lower frame 6 is integrally provided on the lower portion of the upper frame portion 2 on the handle side, and the entire upper frame portion 2 is vertically slidable. In the lower part of the sliding upper frame 13, a foot step 14 for keeping the height of the upper frame portion 2 and a constant height is provided to form a foot storage space 14a. Normally, this is adjusted so that the entire sole of the foot comes into contact when sitting on a seating sling seat, which keeps the foot always in contact with the ground even if the seat height is raised or lowered. It is a feeling. Further, when the foot step 14 descends the upper frame part 2 to a certain height, contacts the lower frame part 3, and further descends the upper frame part 2, the foot step 14 has a structure in which it is pushed forward by an inclined surface provided on the descending frame. There is. This is because the height of the toilet at the time of excretion is generally low.
It is designed so that it does not hit the knee.

There are various methods of raising and lowering the upper frame portion 2, such as an electric method, a hydraulic method, and a mechanical method. However, the raising and lowering method of this embodiment is as shown in the mechanism principle diagram of FIG.
The mechanical system is characterized by low cost. Explaining the lifting principle, it is composed of a lifting operation handle 12, a worm gear 25, a belt winding roller 32 with a gear, a lifting belt 26, a roller A30, and a roller B31, and the lifting belt 26 is a belt winding roller 32.
It passes through the slot provided in, and is twisted 90 degrees symmetrically, passes through the roller B31 and the roller A30, and is fixed to the sliding lower frame 6. In this state, the upper frame part 2 is set to the lowermost part. Lifting operation handle 12
When the is rotated, the force is transmitted by the worm gear 25,
The belt take-up roller 32 rotates to wind the belt, and the belt lengths at both ends are shortened uniformly. Roller A
Since 30 is a pulley and the winding force is reduced by half, the lifting / lowering operation handle 12 of the present embodiment can weigh about 6 kg with a force of about 2 kg.
A person with a disability of 0 kg can be raised and lowered. Further, with the above structure, in the case where the caregiver is left-handed, it can be raised by moving the raising / lowering operation handle 12 in the reverse direction after moving it to the lowermost position, and both rotations can be accommodated. Further, since the worm gear 25 is used, the lifting operation handle 12 can be kept at the set height without being mechanically locked. Further, with the above structure, it is possible to easily reduce the assisting force by electrically using a motor.

As shown in FIG. 2, the sitting position holding sling seat includes: a seat portion 19, a back portion 20, and a belt 17 with a buckle for hanging.
・ 18. Detachable back holding belts 16, 16a, 16b for holding the angle between the seat and the back are integrally formed. -The seat portion 19 and the back portion 20 have a structure in which they can be bent at any angle. -The seat portion 19 and the back portion 20, as shown in the sectional view of FIG.
A hard member 22 is provided so as not to bend even if a weight or leaning force is applied, and a soft member 23 such as foamed urethane is provided so that it is easy to sit on the contact surface side of the body, and the entire surface is sewn with a surface cover 24. , Belts are firmly fixed by sewing. The hard member 22 in this embodiment is a combination of a metal pipe and a veneer material because the seat portion 19 uses a hygroscopic veneer material and the back portion 20 has a waist opening portion 21. The waist open portion 21 has two purposes. (1) In order to hold the sitting position for a long time, one should sit the legs deeply and lean on the back 20, which is for the escape of the waist.
(2) Another purpose is to improve the breathability during the hot summer months. In addition, the back surface of the front cover 24 is made of a slippery cloth, and the seat surface side is intermittently provided with a non-slip rubber material. This is because the sling sheet itself does not easily fall into the front side when sitting, and the sling sheet itself easily rotates with respect to the bed when moving on the bed.

When the back is raised, as shown in FIG. 3, the back holding belt 16 can be fixed on the seat side and the back side with one touch, and there is a length adjusting mechanism on the seat side. The angle can be adjusted.・ As a variation of the seating sling seat, a high back type that can hold the neck and head may be used.

During excretion, a body holder 27 and a thigh holder 29 are used as shown in FIGS. 7, 8 and 9. -Body part holder 27 comprises a body part fixing part 27a and an extension part 27b for detachably fixing the body part on the surface, and the extension part 2 thereof.
A handle fixing hook 28 is attached to the handle 7b, and this hook 28 is fixed to the handle 11, whereby most of the weight of the excretory person is received by the torso holder 27, and the elevator 28 is lifted via the hook 28 and the handle. Be transmitted to. The thigh holder 29 has a plurality of fixing pins 29a.
And a thigh rest member 29b, which is made of a metal member whose surface is covered with a soft material, and serves to support a part of the body weight by the thigh. -In addition, it goes without saying that there is also a sling sheet for excretion in the hammock state of the torso, waist, and thighs, which is a conventional fabric for the purpose of lifting and moving only for excretion directly from the bed.

[0017]

By doing so, it is possible to maintain a true sitting position with the tip of the knee lowered and the sole of the foot touching the ground, which could not be obtained on the bed. Grounding the soles of the feet is the first step in physical recovery. The seat and back structure is made of a hard material that does not bend easily even when a load is applied, so the seat and back surfaces that hold the body are soft materials without being pressed from the side such as the waist. In addition, since the waist is open so that the waist can be seated deeply, a device that can hold a sitting position for a long time can be obtained. In addition, the two arms that suspend the seat serve as armrests, allowing for a more comfortable sitting position. Also, since the entire seat is suspended, even if the body is tilted to the left or right, the entire seat follows the balance and a very good result as a sitting comfort is obtained. In other words, even for a person with a hemiplegic disability, following the seat balance, the two arms that suspend the seat rest on the armrests, and the back support 16a.
Since the 6b belt receives a lateral load, it becomes possible for such a disabled person to hold a sitting position without burdening the nursing power. Conventional sling seats require two steps, one for mounting when putting on the seat and one for removing it when lowering it on a chair, etc. The use can now be long lasting. The whole structure is compact and the four-wheel caster makes it easy to handle when moving. The structure and mechanism are simplified and simplified so that it can be supplied at low cost and home care can be strengthened in terms of social welfare.

As a result, it becomes possible to maintain a true sitting position that cannot be obtained on the bed indoors, and it is possible to recover the muscular strength necessary for daily life even by holding the sitting position for a short time. Since the table 9 is integrally formed on the upper frame portion 2, the same feeling as eating at a normal dining table can be felt and the quality can be improved mentally.

Outside of the bedroom: Since the elevator itself can run on the floor while sitting down, it is possible to move to a room other than the bedroom and have a meal with the family in the dining room.・ Going to the living room seems to give you peace of mind just by watching TV with your family or being at a place where you are chatting.

In excretion: Unlike toilets on diapers and beds, excretion becomes easy in portable toilets in the bedroom and toilets at home, which is the first step of independence.・ Even if you cannot move to the home toilet due to housing conditions, you can easily adjust the height up to the height of the portable toilet,
Since there is a frame space that fits within the width of a portable toilet, it is now possible to use the portable toilet with peace of mind. Even small changes in the environment, such as those seen in the bedroom or out of the bedroom, can provide a good stimulus to bedridden disabled persons and can result in an immeasurable recovery in their mental potential. This is also a proof that the effect of the elevator with the sitting position holding function is great.
