Description

  The present invention can easily move a cared person who needs care such as an elderly person or a physically handicapped person who has weak legs, and in particular, gives a load to the back and waist of the cared person. In addition, the present invention relates to a transfer / movement device that can be used without difficulty even when the spine or the like is damaged, and that can be used as a movement support device by young people as well as healthy people.

  Conventionally, a wheelchair has been widely used as a means for a person who is difficult to walk even if a cane or the like is used for paralysis of the lower limbs to move while operating on his / her own foot. The most popular type of wheelchair is composed of a small front wheel and a large rear wheel attached to a chair. The small wheel is called a caster and is a free wheel that freely turns. The large wheels are drive wheels, and have a traveling ring (hand rim) attached to them, so that they can drive by themselves. In order to operate this at will, in addition to getting on and off training and running training, training in a well-balanced sitting is also important. In the standard type, if the upper limbs are not strong, the operation is difficult to improve. I can say that. Other than wheelchairs, the front large wheel type that is the easiest to operate and suitable for elderly people, one-hand drive type for people who cannot use both hands, manual chain type for outdoor running, hand-held type, prone position running type There are also special types. There are also light and easy to fold and portable, which can easily be put on a car, and for those who cannot operate by hand, there is an electric wheelchair that can be operated simply by pressing a switch.

However, since a normal wheelchair has a backrest behind the seating part and must get on and off from the front, it is necessary to stand up, change the direction of the body and sit down, such as from the bed or toilet seat In general, caregivers should help with the transfer. In particular, when a caregiver who is physically disabled and needs care, such as a bedridden person or an elderly person with weak legs, is to be transferred between a bed and a wheelchair, However, if the caregiver is holding the cared person and supporting the weight, the burden on the caregiver will be large, which may cause back pain, etc. It was. In addition, there is a possibility of falling over due to loss of balance when getting on and off the wheelchair.
In addition, normal wheelchairs also put pressure on the back due to the backrest, but especially in patients with spinal cord injury, loss of sensation due to spinal cord injury can not perceive physical pain and may cause blood flow problems. there were. In addition, the wheelchair sitting posture of patients with spinal cord injury is a posture in which the spinal column is backed and the pelvis is largely tilted backwards, and pressure tends to concentrate in a narrow range compared to healthy subjects, so pay special attention to the sitting posture. It was necessary to take.

On the other hand, when a lifter is used, it takes time and effort to suspend the cared person, which increases the burden on the carer, and also requires a large space for installing and storing the machine. In particular, the structure that suspends the cared person's buttocks has the problem of giving fear and discomfort to the cared person. In the structure that supports the cared person's side, the weight of the cared person is measured on both sides. There was a problem that it had to be supported and caused pain and discomfort to the care recipient.
In addition, the cared person who continues to be bedridden may have a muscle drop and hospitalization may be prolonged. In order to prevent these problems, it is necessary to regularly move the body by assistance or rehabilitation, and frequently change positions, which is a heavy burden on caregivers.
A walker that can alleviate the burden on caregivers and care recipients and is effective for rehabilitation is also used, but there is no seating area, so if you get tired, prepare another chair. It is necessary, and a wheeled walker lacks a sense of stability when it stops because it does not have a stop device, and is particularly unsuitable for use outdoors or on slopes. It was a thing.
The most important issue is the depletion of the human dignity of the cared person. A cared person sitting in a wheelchair feels close to the caregiver during the transfer, is always in a position overlooked by a healthy person while riding, and cannot reach a high object, I was forced to become negative. This led to a decline in the willingness to rehabilitate, and also led to repression of the ego.

In order to eliminate some of these problems, for example, (Patent Document 1) includes a “care chair with a transfer function including a carriage unit that conveys a cared person in a seated state”. It is disclosed.
In addition, (Patent Document 2) states that “a main pillar is erected on a pedestal having a caster, a table and a chair are provided on a hollow shaft fitted to the main pillar, and the table and the chair are arranged along the main pillar. There has been disclosed a “human body moving device for care comprising an elevating device for elevating and lowering”.

However, the above conventional technique has the following problems.
(1) Since the nursing chair with a transfer function of (Patent Document 1) has a backrest behind the seat as in the case of a general chair, the backrest is used until the seat and the backrest are parallel before use. After sitting down or removing the backrest, move the seat on the bed, adjust the height of the seat to the bed height, place the cared person on the seat, The whole nursing chair with a transfer function had to be pulled out of the bed, and the process was complicated and lacked usability.
In addition, there is a problem that in use, there is pressure on the back due to the backrest, which is particularly unsuitable for use by persons with spinal cord injury.
(2) In the human body movement device for care of (Patent Document 2), the chair is formed so as to be able to open both sides by a shaft provided in the center of the rear, and the opened chair is brought into contact from the rear of the waist of the transferred person, The caregiver must lift the left and right thighs of the transferee alternately while inserting the seat into the buttocks, which is troublesome for the caregiver and lacks usability, and the chair structure is complex and mass-productive There was a problem of lacking.
Moreover, since the seat is divided into left and right, there is a problem that the strength is apt to be insufficient, it is difficult to reliably support the weight of the caregiver, and durability and stability of weight support are lacking.
The present invention solves the above-mentioned problems, and can be transferred to and from a bed, toilet seat, etc. without changing the direction of the body, has a simple structure and can be used by one person, and can be used on the back or waist of a cared person.

  Here, the trolley part can be selected in any form, but the front, rear, left and right dimensions of the trolley part are balanced when the cared person rides and the seating part and the breast pad part are rotated or moved up and down. It is preferably formed so as not to collapse and fall. It should be noted that the upper surface of the carriage unit on which the cared person places his / her foot is a flat surface having no irregularities, so that the movement of the foot is not hindered during transfer, and the usability is excellent. The number and arrangement of the wheels of the carriage unit can be selected as appropriate. When two front wheels and two rear wheels are provided, the weight of the cared person can be reliably supported and the transfer / moving device can be moved freely indoors or outdoors, and the weight support and stability of movement are excellent. A motor capable of rotating in the forward and reverse directions is preferably used for the carriage unit. At least one of the front wheel and the rear wheel may be a drive wheel, but all-wheel drive may be used. The driving wheel may be any wheel that can move the main body of the moving / moving device by operating an operating device disposed near the front center of the moving / moving device. In particular, when the trolley part can be moved in all directions, a small turn is effective and the mobility is excellent.

As a power source, a battery can be installed in the cart. In the case where the battery capacity is insufficient and the vehicle cannot run, it is preferable that the caregiver can move by hand by clutch operation. When the driving wheel is disposed in front of the carriage unit together with the power unit and the power source, when the seated part is lowered or tilted while the cared person is seated, the center of gravity moves to the rear of the carriage unit. Can serve as a weight to stabilize the carriage part horizontally. In addition, by making the rotational speed difference between the left and right drive wheels, a right turn or a left turn can be performed, and the rotational radius can be changed by the ratio of the rotational speed difference. In particular, when the rotational directions of the left and right drive wheels are configured to be independently controllable, the vehicle can turn on the spot by rotating one side forward and the other side reversely, resulting in excellent mobility. Further, the front wheel and the rear wheel may be formed to have the same size, and a steering mechanism similar to that of a car or a motorcycle may be provided. This is because it is particularly excellent in running performance and operability outdoors.
As the battery, a rechargeable secondary battery is preferable, and a nickel-cadmium battery, a nickel-hydrogen battery, a lithium ion secondary battery, a lead battery, or the like can be used. In addition, when the battery is removable, it can be driven with another charged battery even while it is charged after removing the empty battery from the transfer / moving device, and it has excellent usability. .

As the brake, a wire having a structure in which a wire is connected to a brake lever and the brake pad is pressed against a rim of a driving wheel by pulling the wire can be used. The brake lever can be installed at any position that is easy for the care recipient to handle, but by placing it near either the left or right side of the chest support part, the brakes can be applied to fix the carriage part during transfer. It can be made excellent in safety.
The wheel can be selected in any form, but when a puncture tire containing urethane foam is used, there is no need to worry about puncture or gas pressure adjustment, and the wheel is excellent in usability. Further, if a suspension is disposed on each drive wheel, a comfortable ride can be achieved.
In addition, by arranging a foot guard formed in a grid shape with metal pipes or the like in front of the carriage portion, it is possible to participate in a competition such as soccer in a standing position.

The seating part supports the caregiver's buttocks and can be selected in any shape, but the width gradually increases from the tip to near the center and then widens at a larger rate as it goes backward from there. When it is formed into a head shape, it does not get in the way during transfer, and does not hinder the operation of the thigh when taking a standing posture by raising the seating portion, and is excellent in usability.
During transfer, the surface of the seat is covered with a material such as leather, polyurethane fiber, or aramid fiber having a low coefficient of friction so that the buttock can be easily slipped on the surface of the seat and moved easily. Many rollers may be provided. In addition, when a foam made of polymer chemicals such as urethane is inserted between the metal base or synthetic resin base of the seating part and the skin, in addition to absorbing vibration and impact, Pressure can be dispersed, nerve compression and blood circulation can be improved, and pain in the buttocks can be reduced. Furthermore, it is also possible to provide a vent hole in the seating part for the purpose of preventing the buttock from being stuffy, and to form the skin with a fabric having a mesh structure.

Although an arbitrary shape can be selected for the chest contact portion, it is preferable to select an area, shape, and hardness that do not give partial pressure or discomfort to the cared person's chest. It is desirable to use a foam (cushion) made of a polymer chemical such as urethane between the base made of metal or synthetic resin and the skin. In addition, for the purpose of preventing the chest from becoming stuffy, a vent hole may be provided in the chest abutting part, or the skin may be formed of a mesh-structured cloth, like the seating part.
A display unit for displaying the remaining capacity of the battery may be provided on the upper surface of the chest support portion that can be directly viewed when the cared person gets on the transfer / movement device. The remaining capacity of the battery can be displayed by changing the color or lighting state of the lamp, so that the cared person can go out in peace.

The drive mechanism part should just be able to rotate or move up and down the seating part and / or the chest part. The seating portion and the chest support portion may be rotated or moved up and down integrally, or may be independently rotated or moved up and down. For example, one that is rotated by a four-bar linkage mechanism, a combination of a rack and a pinion, a link mechanism such as a lazy tong, and one that is moved up and down by an elevating means such as a hydraulic or gas pressure cylinder can be used. The drive mechanism is arranged so that the rear end of the seating part protrudes rearward from the rear end of the carriage part or the rear end of the carriage part when the seating part is moved to the same height as the object to be transferred. Thus, the seating part and the transfer object such as a toilet can be brought close to each other, and a gap is hardly generated between the transfer object and the seating part, so that the transfer work can be easily performed.
The transfer / movement device can also be driven by a remote communication using a mobile communication device such as a mobile phone or a wireless LAN. In that case, move the moving / moving device located at a remote (unreachable) position with a remote control such as a joystick while the care recipient is seated on the bed, etc., and position it at the optimal transfer position. Can be transferred from a bed or the like to a transfer device without the assistance of a caregiver, and the burden on the caregiver can be reduced.

  Here, the shape of the leg holding portion can be selected as appropriate, but it is preferable that it can support a part of the weight of the cared person and can be fixed so that each foot does not move in the lateral direction and the front-rear direction. . What has two knee contact parts in which the horizontal cross section was formed in the substantially semicircular arc shape or the substantially U-shaped notch shape so that the front surface and both side surfaces of each leg may be hold | maintained is used suitably. In particular, in order to softly support the lower part of the cared person's knee (the upper end of the tibia), the knee contact part or the entire leg holding part is formed of an elastic member such as urethane, or the contact surface of the knee contact part It is preferable to partially apply an elastic body.
