[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a stretcher, and more particularly, to a structure that can easily and safely perform an operation of transferring a person who needs assistance such as an elderly person or a sick person who is difficult to walk independently from the bed and returning it to the bed.
[0002]
[Prior art]
In recent years, with the rapid advancement of medical technology, deaths due to illnesses and accidents have greatly decreased, while the number of people requiring assistance such as elderly people and sick people who are difficult to walk on their own tends to increase.
[0003]
Wheelchairs and stretchers are often used to move such care recipients. Since there are many assistive personnel at hospitals and nursing homes, it is possible to transfer a person requiring assistance from a bed to a wheelchair or stretcher, and from a wheelchair or stretcher to a bed by a large number of three or four people. Can do.
[0004]
On the other hand, there is a limit to the number of people who can be involved in assistance in the home, so it is very troublesome to transfer the person who needs assistance, and not only the person who needs assistance but also the person who is in need of physical and mental pain. receive. Furthermore, when the person requiring assistance is heavy, there is a risk that the person will fall over when moving, and there is a risk that not only the person who needs assistance but also the assistant will be in a very dangerous state.
[0005]
Therefore, a stretcher that can be transformed into a wheelchair (see Japanese Patent Application Laid-Open No. 59-160453, Japanese Patent Application Laid-Open No. 04-33654, etc.), the chair part is divided into a seating support and a seat, and the seat is further divided into left and right A wheelchair (see Japanese Patent Laid-Open No. 2000-166974, which can be transferred to an elderly person or a sick person by fixing the seat to a seating support after inserting a seat below the buttocks of an elderly person or sick person sitting on a bed ), The backrest can be folded into two chevron shapes, the backrest and seat can be straightened, placed sideways with respect to the wheelchair frame, and placed on the side of the bed so that elderly and sick people can transfer A wheelchair (see JP 2000-166977 A) has been proposed.
[0006]
By the way, the wheelchair has a structure in which a person requiring assistance sits on the seat, so when carrying a person who needs assistance who cannot support his body, the person who needs assistance may fall off the wheelchair or fall forward There is. Therefore, when a person who needs assistance is carried, a stretcher that can be moved stably in a sleeping posture may be preferable.
[0007]
[Problems to be solved by the invention]
However, the conventional stretcher requires at least two helpers to lift a person who needs assistance when moving the person from the bed and back to the bed, and there are restrictions on the number of people who can be involved in assistance, for example, at home There is a problem that it is difficult to employ in the case of nursing care in the hospital, or in the case of night care or assistance at a hospital or a nursing facility.
[0008]
In view of such a situation, the present invention provides a stretcher that can easily and safely perform an operation of transferring an assisting person such as an elderly person or a sick person who is difficult to walk independently from the bed and returning it to the bed. The issue is to provide.
[0009]
[Means for Solving the Problems]
Therefore, the stretcher according to the present invention is a stretcher suitable for the work of transferring a person requiring assistance from the bed and returning it to the bed, and a suspendable receiving surface member having a size that the person requiring assistance can lie on, A suspension member for lifting and lowering the receiving surface member and at least one movable carriage capable of moving the receiving surface member in a state of being suspended by the suspension member, the at least one movable carriage being rotated A base portion having a free wheel, movably mounted on the floor surface, and capable of being inserted into a gap between the bed and the floor surface; supported by the base portion; A suspension arm portion formed at a height at which the placed receiving surface member can be lifted from the bed and floated, and an upper end portion of the suspension arm portion, and the suspension member is suspended and suspended. Characterized in that it comprises a hanging means down, the.
[0010]
One of the features of the present invention is that the person requiring assistance is placed on the receiving surface member, and the receiving surface member is lifted from the suspension arm portion of at least one movable carriage by the suspension member and lifted from the bed to carry the assistance person. The surface member is suspended on the bed and returned to the bed.
[0011]
When moving a person who needs assistance, such as an elderly person or a sick person who is difficult to walk by himself / herself, from the bed, place the person who is lying on the bed in a recumbent position (sideways) between the back and the bed. Insert the member to return the person requiring assistance to the original supine position, or place a receiving member on the side of the person requiring assistance lying on the bed and receive the head or leg side of the person requiring assistance After placing on the member, the leg side or the head side is placed on the receiving member. When the person requiring assistance is placed on the receiving surface member in this way, the base portion of the moving carriage is inserted between the floor surface and the bed, and the receiving surface member is lifted from the upper end portion of the moving carriage by the hanging member. Can be lifted from the bed, and after that, if the base part of the movable carriage is pulled out from the lower side of the bed, the person who needs assistance can be stably carried in a posture in which the person is required to lie down. When returning to the bed, the reverse of the above may be performed.
[0012]
Therefore, the person requiring assistance can be easily and reliably transferred from the bed to the stretcher, and can be easily and securely returned from the stretcher to the bed by performing the reverse procedure.
[0013]
Moreover, when transferring a person who needs assistance between the stretcher and the bed, there is almost no need for a very harsh and dangerous work in which the assistant has to support a significant part of the weight of the person who needs assistance by himself. There is no physical and psychological burden on the caregiver, and the caregiver has less physical and mental burden.
[0014]
Further, since the person requiring assistance is in the supine position while moving, there is no fear that the person requiring assistance slides down or falls forward like a wheelchair, and the person requiring assistance can be carried in peace.
[0015]
In the present invention, at least one mobile carriage may be used. For example, both the front and rear sides in the longitudinal direction of the receiving surface member may be hung by one moving carriage, but in that case, the stability during movement may be impaired. Therefore, it is preferable that the receiving surface member is lifted and hung by at least two moving carriages.
[0016]
Also, the one end side of the receiving surface member is suspended by at least one moving carriage, and the other end side of the receiving surface member is placed at a height substantially equal to the one end side of the suspended receiving face member by the placing carriage. You may make it do. Furthermore, when there are two or more assistants, the assistant may lift the other end side of the receiving surface member by hand.
[0017]
The movable carriage may have any shape or structure as long as the receiving surface member can be moved while being suspended by the suspension member. For example, the base portion and the suspension arm portion are directly connected to each other at the upper end portions of two pipes having a substantially C-shaped side surface, the remaining portions are separated from each other, and the connection portion is connected to each other with a connecting pipe. Can be formed integrally.
[0018]
The receiving surface member may be any member that can be suspended and has a size that can be placed on the bed and can be laid by a person requiring assistance. For example, a metal plate, a wooden plate, or a synthetic resin plate can be used. Further, a structure in which insertion support portions are provided on both sides of the net body and a support pipe is inserted can be adopted, and such a receiving surface member is a receiver for the shower bed according to the applicant's patent application (Japanese Patent Application No. 2001-31756). It can be used for the body and the shower can be performed more easily and safely.
[0019]
The suspension means may be any mechanism or structure as long as the suspension means is provided at the upper end of the suspension arm and can suspend and suspend the suspension member. For example, the suspension means comprises an operation arm portion and a lock mechanism, the vicinity of the tip of the operation arm portion is rotatably attached to the upper tip portion of the suspension arm portion, and a rope member is locked to the tip of the operation arm portion. A locking part is formed on the other end side of the operation arm part, and a grip part for pressing the operation arm is formed, and the lock mechanism is configured to lock the operation arm part in the pressed state. Can do.
[0020]
Moreover, when using two or more mobile trolleys, or a mobile trolley and a mounting trolley, if the distance between the two fluctuates during movement, it may be difficult to stably carry a person requiring assistance. Therefore, it is preferable to further include a connecting member that removably connects between the moving carriages or between the moving carriage and the mounting carriage.
[0021]
The suspension member may be anything as long as it can suspend the receiving surface member, and a rope, a wire, a chain, an inverted U-shaped arm having hooks at both ends, or the like can be used.
[0022]
Furthermore, according to the present invention, a suspendable receiving surface member which is placed on a bed and has a size capable of being laid by a person requiring assistance, a suspending member for lifting and suspending the receiving surface member, and the receiver It is composed of at least one movable carriage that can move the surface member in a state of being suspended by the suspension member, and is the movable carriage in the stretcher suitable for the work of transferring a person requiring assistance from the bed and returning it to the bed, A base that has a rotatable wheel, is movably mounted on the floor, and can be inserted into a gap between the bed and the floor, and is supported by the base, and at least an upper tip is required. A suspension arm portion formed at a height that can be lifted from the bed on the receiving surface member on which the assistant is placed, and an upper end portion of the suspension arm portion, the suspension member is suspended and suspended. Be equipped with to hanging means, it is possible to provide a mobile carriage for a stretcher characterized by.
[0023]
Also in this movable carriage, any shape or structure may be used as long as the receiving surface member can be moved while being suspended by the suspension member. Further, the suspension means may be any mechanism or structure provided that it can be suspended at the upper end portion of the suspension arm portion to lift and suspend the suspension member.
[0024]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, the present invention will be described in detail based on specific examples. 1 to 8 show a preferred embodiment of the stretcher according to the present invention. The stretcher of this example basically includes a receiving plate (receiving surface member) 10, a rope (hanging member) 20, a moving carriage 30, a mounting carriage 40, and a connecting bar (connecting member) 50.
[0025]
The receiving plate 10 is made of a suitable material, for example, a lightweight metal material, for example, an aluminum-based alloy, and is formed into a thin rectangular plate having a size that can be laid by a person requiring assistance. A pipe 11 to be passed is extended and attached in the width direction, and a lifting handle 12 is fixed to the surface on the other end side.
[0026]
The movable carriage 30 includes a base portion 31, a suspension arm portion 32, and an operation arm portion 35. The base portion 31 and the suspension arm portion 32 directly connect the upper end portions of two metal pipes having a substantially C-shaped side surface to each other, separate the remaining portions from each other, and connect the two connecting pipes 33 therebetween. Are integrally formed with each other.
[0027]
A caster (wheel) 34 capable of rotating and turning is attached to the base portion 31 at positions corresponding to the four corners, and is set to a height that can be inserted between the floor surface and the bed.
[0028]
The upper end of the suspension arm 32 is set to a height at which the receiving plate 10 on which a person requiring assistance is placed can be lifted from the bed and floated. An upper end portion of the suspension arm portion 32 is rotatably attached to the vicinity of the distal end of the operation arm (suspension means) 35 by a horizontal pin 36, and an engagement hook 37 for engaging the rope 20 is attached to the distal end of the operation arm 35. Installed.
[0029]
The operation arm 35 has substantially the same shape as the suspension arm portion 32, and a grip 38 for pushing the operation arm 32 down is provided on the base side, and a pin hole (lock mechanism, suspension means) is provided in the vicinity of the grip 38. 39 is formed. On the other hand, a pin hole (lock mechanism, suspension means) 310 is formed in the suspension arm portion 32 at a position corresponding to the pin hole 39 of the operation arm 35, and the connection holes (lock mechanism, suspension) are aligned with the pin holes 39, 310. Means) By inserting 311, the operation arm 35 can be locked in the depressed state.
[0030]
The mounting carriage 40 is provided with a receiving portion 41, the height of the receiving portion 41 can be adjusted by a known mechanism, and the other end side of the receiving plate 10 is suspended by the moving carriage 30. It can be placed at a height substantially equal to the one end side. In addition, casters 42 are attached to the bottom four corners of the mounting carriage 40.
[0031]
In addition, the mobile carriage 30 and the mounting carriage 40 are provided with hooks 51 and 52 into which the connecting bar 50 can be fitted, and the mobile carriage 30 and the mounting carriage 40 are mutually in a state where the mobile carriage 30 is turned sideways or forward. It can be connected.
[0032]
For example, when a bedridden elderly person is moved using the stretcher of this example, the assistant places the receiving plate 10 on the side of the elderly person lying on the bed, as shown in FIG. At this time, the rope 20 is inserted through the pipe 11 of the receiving plate 10 in advance.
[0033]
When the receiving plate 10 can be set in this way, the caregiver places the old man on the plate 10 by a normal method. For example, when an elderly person in a supine position is placed in a supine position and the receiving plate 10 is inserted between the back and the bed and the elderly person is returned to the original supine position, the elderly person can be placed on the receiving plate 10. The Further, after placing the elderly person's head side on the receiving plate 10, the foot side is placed on the receiving plate 10, or conversely, the foot side is placed on the receiving plate 10, and then the head side receiving plate 10. It can be placed on the top, and thus an elderly person can be easily placed on the plate 10 by a single assistant.
[0034]
Next, the movable carriage 30 and the movable carriage 40 are moved to the bed side so that the distance between them corresponds to the length of the connecting bar 50, and the base portion 31 of the movable carriage 30 is inserted between the bed and the floor surface. After the upper end portion of the suspension arm portion 31 is positioned above the pipe 11 of the plate 10, the grip 38 of the operation arm 35 is pushed upward, the both end portions of the rope 20 are hooked on the end hook 37, and the operation arm 35 is When the clip 38 is pushed down and the pin hole 39 of the operation arm 35 and the pin hole 310 of the suspension arm portion 32 match, the connecting pin 311 is inserted into both the pin hole 39 and the pin hole 310 of the suspension arm portion 32, and the operation arm 35 is suspended. When locked to the arm portion 32, one end side of the receiving plate 10 is lifted and held in a state of floating from the bed.
[0035]
In such a state, at least half of the weight of the elderly person is shared by one end of the receiving plate 10 and supported by the rope 20, so that the other end of the receiving plate 10 can be lightly lifted by one assistant. Therefore, the assistant holds the handle 12 on the other end side of the receiving plate 10 and lifts the receiving plate 10 to place it on the receiving portion 41 of the mounting cart 40, and finally hooks 51, 52 of the moving cart 30 and the mounting cart 40. The connecting bars 50 are fitted to each other and connected to each other.
[0036]
In this state, since the movable carriage 30 and the mounting carriage 40 move integrally, the base portion 31 of the movable carriage 30 can be pulled out from the lower side of the bed and moved forward or backward.
[0037]
If there is not enough space on the side of the bed to move the movable carriage sideways, the movable carriage 30 and the loading carriage 40 are connected by the connecting bar 50 before the receiving plate 10 is placed on the mounting carriage 40. When the moving carriage 30 is turned forward while the base 31 of the moving carriage 30 is pulled out from the lower side of the bed before the moving carriage 30 and the mounting carriage 40 are connected in this state, the space on the side of the bed is narrow. The moving carriage 30 and the mounting carriage 40 can be moved inside.
[0038]
In order to return the elderly person to the bet, the reverse operation may be performed, and since it can be easily understood from the above description, the detailed description thereof is omitted.
