Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mobile lifter, and particularly to a mobile lifter without causing pain to an assisting person such as an elderly person or a sick person whose muscle strength is weak, and without causing pain or mental burden to the assisting person. The present invention relates to a mobile lifter which enables a caretaker to be safely transferred from a bed to a mobile lifter and from the mobile lifter to a bed or a passenger compartment of an automobile.

[0002]

2. Description of the Related Art In recent years, with the rapid progress of medical technology,
While deaths due to illness and accidents have decreased significantly, on the other hand, the number of elderly and sick people who have difficulty walking on their own tends to increase, and the care and care of such elderly and sick people has become a major social problem.

When an elderly person or a sick person (hereinafter referred to as a person requiring care) who is difficult to walk by himself is moved from the bed and returned to the bed,
The caregiver has an elderly person or a sick person according to a care manual,
Transferring from the bed to a wheelchair or stretcher, or back to the bed from the wheelchair or stretcher is performed.

By the way, in hospitals and nursing homes, etc., where staff members are required to assist, it is relatively easy to safely move a person requiring assistance from bed to wheelchair or from wheelchair to bed, even though the caregiver is physically burdened. Is. However, since there is a limit to the number of people who can be assisted at home, it is very difficult to move from bed to wheelchair, or from wheelchair to bed. Suffer physical and mental distress. In addition, if the care-requiring person has a heavy weight, he or she may accidentally fall down while moving.
Not only the person requiring care, but also the person who needs help may be in a very dangerous state.

Therefore, a bed that can be transformed into a wheelchair (Japanese Patent Laid-Open No. 59-160453 and Japanese Patent Laid-Open No. 04-
(See No. 33654, etc.), the chair part is divided into a seating support and a seat, and the seat is further divided into left and right, and the seat is inserted under the buttocks of an elderly person or a sick person sitting on the bed, and then fixed to the seating support. Wheelchairs that enable the elderly and sick people to be transferred (Japanese Patent Laid-Open No. 2000-166)
No. 974, reference), etc. have been proposed.

However, the system in which the bed is transformed into a wheelchair has a very complicated structure, which increases the cost and is difficult to adopt for home care.

Further, in the method of inserting the seat from the left and right, the buttocks may be caught in the seat when the seat is inserted to the lower side of the buttocks, and in order to avoid this, it is necessary for the caregiver to lift while holding the body of the elderly or sick. There is a physical and mental burden not only on the elderly and sick but also on the caregiver.

On the other hand, the chair portion is divided into a support and a seat portion, and the seat portion is configured to be able to be lifted with respect to the support. There has been proposed a moving lifter in which the seat portion is lifted from a bed surface after being seated in a sitting posture, and the seat portion is lifted from the bed surface and pulled out (see Japanese Patent No. 2796620).

[0009]

However, in the above-mentioned movable lifter, when the person requiring assistance sits on the seat in the end sitting posture,
Depending on the person requiring care, there is a risk of falling forward or sideways.In such a case, it is necessary to support the person with one hand while handling the wheelchair with the other hand, which is extremely dangerous. Is.

Further, in the above-mentioned moving lifter, when a person requiring assistance moves from a wheelchair to a seat of an automobile, the person requiring assistance takes a sideways posture, so that the person requiring assistance needs to hold it with both hands and recline forward. There was room for improvement in this respect.

In view of such a situation, the present invention provides a person requiring assistance between the bed and the movable lifter, and an automobile, without imposing physical and mental burdens on the person requiring assistance as well as the person requiring assistance. It is an object of the present invention to provide a mobile lifter that can be easily and safely transferred between a seat and a mobile lifter.

[0012]

Therefore, the movable lifter according to the present invention has a long sitting position in which a person requiring assistance in a supine position is transferred, the legs are bent, and the upper half of the body is inclined obliquely rearward, Furthermore, it is a moving lifter suitable for the work of returning to the original supine position while taking the end sitting position, and is composed of a chair, a trolley and a lifting mechanism, and the chair includes a removable receiving member. , The receiving member is composed of a leg receiving portion, a seat portion and a backrest portion, and the leg receiving portion, the seat portion and the backrest portion receive the upper body from at least the thigh of the person requiring assistance in a supine position. While it can be deployed in a flat state, it can be bent into a three-dimensional shape that keeps the person requiring assistance in a sitting position when attached to the chair, and the trolley can be moved at least in the front-rear direction and the left-right direction. Provided on the side A suspension strut is erected, and the lifting mechanism is provided for suspending the trolley with the chair positioned to the side of the chair so that the person requiring assistance sitting in the chair can assume the long sitting position or the end sitting position. The feature is that it is hung from a hanging column.

One of the features of the present invention is that the chair receiving member is laid flat on a bed, a futon or a tatami mat, and a person requiring assistance is placed in a supine position, and the receiving member is attached to the chair so that the receiving member is fixed. Bend it so that the person requiring assistance sits down,
The point is that the chair is hung from the hanging column of the trolley by the lifting mechanism to a long sitting position or even an end sitting position.

As a result, when the person requiring care on the bed takes a supine posture from the supine posture, and when the receiving member is deployed to the side and returned to the position above, the person requiring care takes a supine posture. When the receiving member is attached to the chair, the posture is such that the legs are bent, and after that, the receiving member can be transferred to the moving lifter only by mechanical operation. As a result, there is no need for the person requiring care to sit on the bed in the end-sitting posture, the person needing to support the person requiring care with one hand, and the person being able to concentrate on handling the mobile lifter can be physically assisted. The burden can be greatly reduced.

Further, since the person requiring assistance bends his / her legs from the supine position and is lifted while shifting from that position to the sitting position, he / she may fall forward or sideways when transferring to / from the moving lifter. There is no risk of falling down toward the person, the safety of the person requiring care can be secured, and the mental burden on the person requiring care can be reduced.

Further, in the mobile lifter described in the above-mentioned prior art, when a person requiring assistance moves from the mobile lifter to the seat of the vehicle, the person requiring assistance takes a sideways posture with respect to the seat, and therefore the person holding the assistant with both hands holds it. There is room for improvement in this respect. On the other hand, in the present invention, since the trolley can be moved in the left-right direction and lifted and lowered while the person requiring assistance is in a forward-looking posture, it can be directly seated on the seat of the automobile from the moving lifter.

Further, since the movable lifter is constituted by the chair, the trolley and the lifting mechanism, the structure is simple, the cost is not increased, and it can be easily adopted for home care.

Here, there are two sitting postures, one in which the legs are thrown forward and the upper half of the body is raised, and the other in which the legs are bent and the upper half of the body is slanted backward. Since the latter is more stable and safe, the present invention refers to the latter sitting position.

The receiving member may be attached to and detached from the chair, but from the viewpoint of weight reduction, it is preferable that the chair is composed of a holding frame and a receiving member that can be engaged and disengaged from each other.

The holding frame may be constructed such that the holding frame is assembled and attached to a receiving member placed flat on a bed, a futon or a tatami mat, but the burden on the caregiver is large. Therefore, if the holding frame is formed into a flat shape that can be covered from above the flattened receiving member, the receiving member is received in the supine position, and then the holding frame is covered from above to attach the receiving member to the holding frame. , The burden on caregivers can be significantly reduced.

However, in order to easily work when attaching the receiving member to the holding frame, the holding frame is composed of a main body portion to which the leg receiving portion of the receiving member, a seat portion and a backrest portion are attached, and a front leg, It is preferable that the front leg be detachable from the main body.

The dolly may have any structure and shape as long as it is movable in at least the front-rear direction and the left-right direction, and the suspension columns are erected on the side portions. For example, the hanging pillar can be configured in a substantially inverted L shape on the front surface, which includes a pillar body extending vertically upward and a horizontal rod extending horizontally from the upper end portion of the pillar body in the lateral width direction of the trolley.

In order to assist the person requiring care, it is desirable that the person requiring care on the bed can be smoothly transferred to the chair. Therefore, it is preferable that the trolley has a shape in which the lower base portion can be inserted into the gap between the bed and the floor surface.

Further, it may be necessary to smoothly transfer the person requiring assistance lying on the futon to the chair. Therefore, it is preferable that the lower base part of the trolley is formed into a substantially U-shape in plan view, and casters are attached to the four corner cat parts.

The hoisting mechanism is not limited so long as it is possible to make the person requiring care sitting on the chair by suspending the chair from the hanging column of the trolley with the chair positioned to the side, in the sitting position or the end sitting position. Such a structure or method may be used.

For example, the hanging column has a substantially inverted L-shaped front surface including a column main body extending vertically upward and a horizontal rod extending horizontally from the upper end portion of the column main body in the lateral width direction of the trolley. The left and right wound bodies that are hooked on the holding frame of the chair can be made profitable, and the left and right wound bodies can be wound by the winding rollers on both sides of the horizontal rod portion of the hanging column. The material to be wound may be a rope or a chain, or a belt-shaped member such as a belt can be adopted.

Further, the lifting mechanism may be constructed such that the take-up roller is rotated or reversely rotated by manual operation, or the take-up roller is rotated or reversely rotated by rotation or reverse rotation of the drive motor. Good.

By the way, the above-mentioned chair comprising a holding frame and a receiving member is also novel. That is, according to the present invention, a person requiring assistance in a supine posture is transferred,
A movable lifter with a trolley and a lifting mechanism that is suitable for bending the legs and tilting the upper body diagonally rearward to a long sitting position, and even an end sitting position and returning to the original supine position A chair that comprises a holding frame and a receiving member that are detachable from each other,
The receiving member is composed of a leg receiving portion, a seat portion and a backrest portion, and the leg receiving portion, the seat portion and the backrest portion receive the body above at least the thigh of the person requiring assistance in a supine position. It is possible to provide a chair for a moving lifter, which is capable of being deployed in various states, and can be bent into a three-dimensional shape that keeps a person requiring assistance in a sitting posture when attached to the chair. .

A person who needs help sitting in a chair not only feels anxious when his / her feet are floating in the air, but also the back side of the knee and the back side of the thigh are squeezed to form blood clots in the foot. If a blood clot separates and flows out due to the cause, it may clog the capillaries of the brain, heart, or lungs, causing cerebral infarction, myocardial infarction, heart attack, pulmonary thrombosis, and the like. Therefore, it is preferable to provide a foot rest on the holding frame for placing the foot of the person requiring care and forming a gap between the receiving member and the back of the knee.

The holding frame and the receiving member of the chair may be detachable by any method. For example, locking holes may be provided in the receiving member, locking hooks may be provided in the holding frame, and the locking holes may be hooked on the locking hooks to engage with each other. It is annoying to hook on the hook by hand.

Therefore, rods are detachably attached to both side edges of the receiving member, a plurality of locking projections are formed on both outer edges of the holding frame, and the rod is hooked on each of the plurality of locking projections. It is preferable that the receiving member is attached to the holding frame by locking the rod to the locking projection in response to the weight of the person requiring assistance.

The lifting mechanism is designed to hold the chair in a long sitting position or an end sitting position by hoisting the chair, but it is possible for a person requiring care to be kept in the long sitting position or the end sitting position. A support member for supporting the chair,
Preferably, it is provided so as to be freely attached and detached.

When the person requiring assistance is placed on the seat of the vehicle, the chair may be lowered and placed, but considering the comfort of the person requiring assistance and workability when returning from the vehicle to the moving lifter, It is preferable to remove the holding frame and leave the receiving member.

A plate member may be used as the receiving member, and a cushioning material may be attached to the surface of the receiving member if necessary. However, a member in which a plurality of belt-like members are hung between a pair of rods at intervals, or It is preferable to use a sheet-shaped member. Also,
Since it is more convenient to use a shower, the receiving member may be formed by stretching a net body, or a hole may be formed at a position where the bottom of the sheet-shaped receiving member hits.

Further, when the care-requiring person has a bed sickness or the like, the bed sickness may be aggravated if the chair is left sitting on the chair for a long time. Therefore, if a hole is made in the receiving member at a position corresponding to the bed sore of the person requiring care, pressure on the affected area can be eliminated, the affected area can be dried, and the cause of bed sore can be removed.
