A pedestal having a running part, a seating part disposed on the pedestal and seated by the user from the back or side, and a chest part standing on the front end side of the seating part and contacting the chest of the user; And at least one of the seating portion and the chest support portion is held movably in the front-rear direction or the vertical direction with respect to the base portion.
The present invention can be easily used by a cared person who needs care, such as a healthy person, an elderly person with a weak leg, a physically handicapped person, etc. It can be used without any load on the back and waist, especially when the user's spine is damaged, and it can be easily transferred to a bed, toilet seat, wheelchair, etc. The present invention relates to a transfer / movement device.
2. Description of the Related Art Conventionally, wheelchairs in which a person who has difficulty walking even with a cane or the like due to paralysis of the lower limbs can be moved while being operated by himself instead of his / her foot are widely used. 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, it is important to have a well-balanced training in addition to getting on and off and running training. In the case of the standard type, the operation is difficult to improve unless the muscle strength of the upper limb is strong. 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 When transferring, I often had to get help from my caregiver.
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, a fall accident may occur due to a loss of balance when getting in and out of a wheelchair, resulting in lack of usability.
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.
In order to solve these problems, for example, (Patent Document 1) discloses a “care chair with a transfer function including a carriage unit that conveys a cared person in a seated state”. Yes.
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”.
