To get the person F for care off the stretcher 1, first and second supports 12, 13 are both rotated in a direction for extending a sheet 16 so as to loosen the sheet 16 to lower the person C for care; to return the person C for care onto the stretcher 1, the supports 12, 13 are rotated in the opposite direction so as to wind the sheet 16 to lift the person C for care.

Description

Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to a stretcher for placing and transferring a care receiver.

[0002]

2. Description of the Related Art There is a stretcher as a means for transferring a cared person in a hospital or a nursing home. As this stretcher, for example, as shown in FIG.
A pedestal 101 on which a cared person is placed is supported by a column 102, and a column 103 is provided with a caster 103 for movement.

[0003]

When the care receiver is moved from the bed to another place by using the stretcher, the caregiver holds the care receiver and moves the care worker from the bed onto the stretcher. That work is required first. However, if one person tries to move while lying down, even if the caregiver is strong, at least two caregivers are needed, and the care recipient is forced into an unreasonable posture. If you try not to do so, the task will be very difficult.

Therefore, various transfer means have been proposed in order to easily move the care receiver. For example, in US Pat. No. 5,038,424, a support surface for supporting a patient on a lift system movable by wheels is used.
face) is arranged along the long side edge of the bed, and the long side edge of the bed opposite the table side and the length of the table opposite the bed side. Disclosed is a cared person transfer system in which rollers are rotatably supported at respective side edges, and both ends of a flexible web are fixed and wound around the rollers. Has been done. According to this transfer system, the care receiver is placed on the web, and in this state, the roller is rotated by the motor to feed the web in one direction, thereby transferring the care receiver on the web from the bed to the table. Can be changed.

However, in the above-mentioned transfer system, since the support shafts are attached to both the table and the bed and the web is passed between the support shafts, the care receiver is placed on the table and placed at another place. It is necessary to remove the support shaft attached to the bed and attach it to the table when transferring it to the table, but there is a problem that the work of replacing the support shaft is troublesome. Further, there is a problem that it is necessary to provide a mechanism for supporting the support shaft on the bed.

Further, in the above-mentioned transfer system, when the cared person is lowered from the table or returned to the table, for example, when the cared person takes a bath in a bathtub installed on the floor. In the end, it is necessary to carry the cared person while moving.

The present invention has been made to solve such a problem, and an object of the present invention is to safely and safely perform the work of moving a care receiver in a horizontal direction or a vertical direction with minimum labor. It is to provide a stretcher that can be easily performed and has a simplified mechanism.

[0008]

A stretcher according to the present invention made to solve the above-mentioned problems has a plurality of columns having casters at its lower end, and includes a first support shaft and a second support shaft. However, both ends are rotatably supported by the support column so that they are substantially horizontal and parallel, and the both support shafts are driven by motors, respectively, and are longer than the distance between the both support shafts. A sheet made of a material having a smoothness such that the care receiver can be slid and moved is stretched between the both support shafts by winding both ends thereof, and the both support shafts are supported. In between, the cared person can be supported only by the seat.

[0009]

BEST MODE FOR CARRYING OUT THE INVENTION When a cared person is transferred, one long side portion of a stretcher is horizontally attached to one long side portion of a bed so that their heights are substantially the same. Slide the cared person above to the center of the stretcher. When lowering the care receiver from the stretcher, lower the care receiver by loosening the seat by rotating both the first and second support shafts in the direction in which the seat is rolled out, and then returning to the stretcher. In this case, both support shafts are rotated in the opposite direction to the above to wind up the sheet, and the care recipient is lifted.

[0010]

[Effect] According to the stretcher of the present invention, the care receiver is slid to move from the bed to above the stretcher, so that even one care worker can put the care receiver on the bed in a substantially sleeping position. You can move it from the bed onto the stretcher without changing its posture. Therefore, this stretcher becomes a particularly useful transfer means in the case of transferring a cared person whose change of posture causes pain. Furthermore, it is not necessary to provide a special mechanism on the bed, and the operation is simple and the cost can be suppressed. Furthermore, since the care receiver is supported only by the seat on the stretcher, the seat can be loosened and the care receiver can be lowered to take a bath, and the vertical movement can be easily performed.

[0011]

The present invention will be described below with reference to examples. FIG.
Is a front view showing an embodiment of the stretcher of the present invention,
FIG. 2 is a side view of FIG. The stretcher 1 shown in FIGS. 1 and 2 has four columns 11 each having a caster 111 at a lower end portion thereof, and has first and second support shafts 12 and 1.
Both ends of each of the shafts 3 are rotatably supported by the column 11 so that they are substantially horizontal and parallel to each other. Each of the support shafts 12 and 13 is configured to be driven by a motor (only the motor 14 for the support shaft 13 is shown in FIG. 2) at one end. A sheet 16 longer than the distance between the support shafts 12 and 13 is wound around the support shafts 12 and 13 at both ends, whereby the seat 16 is wound.
Is stretched between both support shafts 12 and 13.

One end of the first support shaft 12 is connected to a motor via a speed reducer (not shown) (reduction ratio is preferably about 1/50 to 1/60). Similarly, the second support shaft 1
One end of 3 is connected to another motor 14 via a speed reducer. A brake (not shown) is provided on each of the support shafts 12 and 13 or their motors, so that even if a strong tensile force is applied to the seat 16, the support shafts 12 and 13 are reversely rotated and unwound. There is no. In addition, this brake,
For safety in the event of a power failure, it is desirable to release the brake when energized and to tighten the brake with a spring when de-energized.

One of the support shafts 13 is held by a column 11a so as to be able to move up and down. A mechanism known in the art may be used as the lifting mechanism for the support shaft 13. For example, the pillar 11
It is possible to provide a leaf spring on each upper part of a and fix both ends of the support shaft 13 to the tip of each leaf spring. In this aspect, the strength of the both leaf springs is set so that the force of the both leaf springs to pull up the support shaft 13 becomes substantially equal to the weight of the support shaft 13 (including the motor 14). When,
The support shaft 13 can be manually moved up and down with a light force. The stopper 1 is attached to the column 11a that supports the support shaft 13.
7 are respectively provided, whereby the support shaft 1 is provided.
3 is fixed in the state of being pulled up to the uppermost end.

FIG. 3 is an enlarged view of the stopper 17. As shown in the figure, the stopper 17 has a support portion 171 for supporting the support shaft 13 and a grip portion 172, and the support point 17
3 is pivotally supported by the column 11a. Bearing part 171
The arcuate portion 171a supporting the support shaft 13 at the
It has an arc shape having a center 171b slightly below 73. Therefore, the support shaft 13 placed on the arc-shaped portion 171a has the free end side (the left side in FIG. 3) of the arc-shaped portion 171a.
It becomes higher in the gravity direction as it goes toward, and conversely becomes lower in the gravity direction as it goes toward the handle portion 172 side.
This prevents the stopper 17 from naturally rotating due to the weight of the support shaft 13 and causing the support shaft 13 to slide down from the arc-shaped portion 171a.

A sheet 16 is stretched between the first and second support shafts 12 and 13 by winding both ends thereof, respectively. The sheet 16 is made of a material that has flexibility and sufficient tensile strength so that it can be wound around a spindle. For example, a nylon material having a thickness of about 0.2 to 0.5 mm (preferably about 0.25 to 0.30 mm) can be exemplified. Further, since the seat 16 has a smoothness such that the care receiver C can be slid and moved on the seat 16, friction between the care receiver C and the second moving seat 3 described later is provided. It is made of a material with a small coefficient. Examples of the material of such a sheet 16 include the same materials as those of the first moving sheet 2 described later.

Each of the columns 11 is provided with an appropriate height adjusting mechanism so that the height of the seat 16 can be adjusted according to the height of the bed. For example, in the column 11 on the bed 4 side, a screw is axially passed through each column 11, and female threads are provided at both ends of the support shaft 12 so that the screw is axially supported by the female thread. A method of raising and lowering the support shaft 12 by rotating it can be mentioned. On the other hand, on the column 11a on the side opposite to the bed 4, a plurality of holes for supporting the stoppers 17 are provided so as to be aligned in the vertical direction, and the mounting position of the stoppers 17 is changed up and down step by step. There is a method of adjusting the height. A caster 111 for movement is provided at the lower end of each column 11.

The support 11 on the bed side and the support 11a on the opposite side are connected by a support rod 112. The support rod 112 is provided with a length adjusting mechanism (not shown), which allows the width of the stretcher 1 to be changed according to the size of the installation location or the like. As a length adjusting mechanism of the support rod 112, one of two pipe-shaped support rods having different thicknesses is inserted into the other, and a pin is inserted at a predetermined length position at a portion where the both support rods overlap. Known ones such as those which are inserted and fixed are exemplified.

The second moving sheet 3 is for placing the care receiver C on it and moving it from the bed to the stretcher (and vice versa). The second moving sheet 3 has a thickness of about 1 to 3 mm and is formed in a rectangular shape having a length and a width substantially equal to those of the care-receiver C.

At both edges on the long side of the second moving sheet 3, an appropriate number (for example, 4 to 8) of handle holes or handles (for example, 4 to 8) are provided for the convenience of moving the care receiver C. (Not shown)
Is provided.

The first moving sheet 2 is laid on the mattress of the bed 4, and the second moving sheet 3 is moved on the mattress. The first moving sheet 2 has a length substantially equal to the body length of the care receiver C and the bed 4
Formed in a rectangular shape with a width slightly larger than the width of
It is fixed so as to cover the upper surface of the mattress of the bed 4 by an appropriate fixing means.

As the second moving seat 3 and the first moving seat 2, it is easy to slide the second moving seat 3 on the first moving seat 2 to move it. A material having a small friction coefficient is used. Examples of such materials include "Tetoron [taffeta] cloth" and "Tetoron [taffeta 130 umbrella]" manufactured by Toray Industries, Inc., and nylon cloth that has been subjected to acrylic treatment, silicone treatment, calendar treatment, etc. Is mentioned.

FIG. 4 is a diagram showing a method of using the stretcher of the present invention. Hereinafter, a procedure for moving the care receiver from the bed to another place will be described with reference to FIG.

First, as shown in FIG. 4A, the bed 4
The first moving sheet 2 and the second moving sheet 3 are laid between the mattress and the cared person C, and the stretcher 1 is horizontally attached to one long side of the bed 4.

The first moving seat 2 is fixed so as to cover the upper surface of the bed by an appropriate fixing means as described above, and the second moving seat 2 is fixed between the first moving seat 2 and the care-receiver C by the second. Then, the moving sheet 3 is inserted. When the first moving sheet 2 and the second moving sheet 3 are laid under the care-receiver C, it is not always necessary to lift the care-receiver C, and the care-receiver C can be turned over from side to side. The sheets 2 and 3 may be laid under the care-receiver C one by one while being hit.

The height of the seat 16 of the stretcher 1 is made substantially the same as the height of the upper surface of the bed 4 by the height adjusting mechanism (not shown) as described above.

Then, as shown in FIG. 4 (b), the second moving seat 3 on which the cared person C is placed is pulled in the direction of the arrow A, and the second moving seat 3 is stretched. 1 Slide it to the center and move it.

As described above, the first moving seat 2,
Since the second transfer sheet 3 and the sheet 16 are made of a material having a small friction coefficient, the second transfer sheet 3 has a relatively small force even when the care receiver C is placed. You can pull it with. At this time, if the head side and the leg side of the second moving seat 3 are alternately pulled, this moving work can be performed more easily. In this embodiment, the care receiver C is slidably moved from the bed 4 to the stretcher 1 using the first moving seat 2, the second moving seat 3 and the seat 16 in this way. Therefore, it is not necessary to provide a special mechanism on the bed 4, and the operation is simple.

After the cared person C is placed on the stretcher 1 as described above, the casters 111 of the columns 11 are placed.
Thus, the stretcher 1 is moved and the care receiver C is transferred to the intended place. When the care-receiver C is returned to the bed after the transfer, the procedure opposite to the above may be performed.

In the case of performing vertical movement such as lowering the care receiver from the stretcher or returning to the stretcher, such as when taking a bath, the first and second operations are performed.
The cared person is lifted up and down by rotating the support shaft and loosening or tensioning the seat. FIG. 5: is a figure which shows an example of the procedure of bathing a cared person using the stretcher of the said Example. This work will be described below with reference to FIG.

First, as shown in FIG. 5 (a), with the cared person C placed, the stretcher 1 is moved onto the bathtub 5 (or the bathtub 5 is moved below the stretcher 1). ), So that the care receiver C is almost directly above the bathtub 5. The procedure for placing the care receiver C on the stretcher 1 may be the same as that shown in FIG.

Next, as shown in FIG. 5 (b), the first and second support shafts 12 and 13 are both rotated in the direction in which the seat 16 is unwound to loosen the seat 16, and the care receiver C To the bathtub 5 for bathing.

At this time, the care-receiver C is seat 1 while descending.
Since the pressure is applied from both sides by 6, it is desirable that the second moving sheet 3 be capable of holding a flat plate shape even when the care-receiver C is weighted. Examples of the material of the second moving sheet 3 include synthetic resin such as low foam resin. Further, the seat 16 and the second moving seat 3 may be provided with a large number of small holes (not shown) in order to facilitate discharge of hot water when the care receiver C is lifted from the bathtub 5. desirable. Further, the width of the seat 16 and the length of the second moving seat 3 need to be slightly smaller than the inner length of the bathtub 5, and the width of the second moving seat 3 is smaller than that of the inner bathtub 5. It needs to be slightly narrower than the width. Further, the length of the sheet 16 is the first and the second.
The length is such that it reaches the bottom of the bathtub 5 when it is unwound from the spindles 12 and 13. Furthermore, the sheet 16 and the second moving sheet 3 are preferably made of a material having water resistance, and further, it is desirable that the surface thereof be subjected to a water repellent treatment (coating).

The bath tub 5 may be preliminarily filled with hot water as shown in FIG. 5, or the care receiver C may be lowered into the bath tub 5 and poured into the bath with a shower or the like. You may do it.

Next, as shown in FIG. 5C, the support 1
The handle portion of the stopper 17 of 1a is pulled to the outside to tilt the stopper 17, whereby the second support shaft 13 is released from the fixed state and pulled down to a position close to the side edge of the bath 5.

By pulling down the second support shaft 13 as described above, one side of the bathtub 5 is opened. The body of the care-receiver C is washed from the opened side.

After bathing, the motor is rotated to unwind the sheet 16 and the second support shaft 13 is pulled up to the uppermost end of the column 11a and fixed again by the stopper 17. Then, the first and second support shafts 12 and 13 are both rotated in the direction in which the seat 16 is wound, and the care receiver C is slowly lifted from the bathtub 5. When the care-receiver C rises a little from the surface of the bath, the motor is temporarily stopped and drained. In this state, the body of the care-receiver C may be wiped with a towel. After that, both the support shafts 12 and 13 are further rotated in the direction in which the sheet 16 is wound, and the sheet 16 is tensioned.

In addition, it is preferable to form the bathtub 5 so that the head side is shallow, or to put an appropriate pillow on the head side in the bathtub 5. According to this, the care recipient C can be When descending into the bathtub 5, the head of the care-receiver C moves to the bathtub 5
The head is prevented from sinking in hot water because it abuts on the shallow part of the floor or the pillow.

In the stretcher of the above-mentioned embodiment, when raising and lowering the care-receiver, the sheet is unrolled or rolled up by the rotation of both support shafts. As shown in FIG. The cared person can be moved in the horizontal direction by using the unwinding or winding of the sheet by rotating the both support shafts. Hereinafter, such a method of moving the care receiver will be described with reference to FIG.

First, as shown in FIG. 6A, the bed 4
The first moving sheet 2 and the second moving sheet 3 are laid between the mattress and the cared person C, and the stretcher 1 is horizontally attached to one long side of the bed 4. This operation may be the same as that shown in FIG.

Then, as shown in FIG. 6 (b), the second moving seat 3 is pulled in the direction of the arrow A, and the end edge of the second moving seat 3 on the stretcher 1 side is stretched. The lettcher 1 is placed on the edge of the seat 16 on the bed 4 side.

In this embodiment, the movement of the second moving seat 3 from the bed 4 to the end edge of the seat 16 on the bed 4 side is carried out in the same manner as the operation shown in FIG. 4 (b). It is done by sliding No. 3.

Next, as shown in FIG. 6C, the first support shaft 12 is rotated in the direction in which the sheet 16 is wound, and the second support shaft 13 is rotated in the direction in which the sheet 16 is wound. Then, the seat 16 is sent out in the direction opposite to the bed side, whereby the second moving seat 3 on which the care receiver C is placed is moved to the center of the stretcher 1.
At this time, as the seat 16 of the stretcher 1, the second
If a material having a large friction coefficient with the moving sheet 3 is used, the sheet 3 can be pulled out only by placing the end of the second moving sheet 3 on the sheet 16 as it is. Alternatively, a fixing means such as a velcro is provided at an end edge portion of the second moving sheet 3 on the stretcher 1 side and an appropriate position (or the entire surface) of the sheet 16, and thereby the second moving sheet 3 is fixed. It may be fixed on the seat 16. In the latter case, the seat 16 itself is made of a material having a small friction coefficient with the second moving seat 3 (that is, the same as the first moving seat 2 as in the embodiment shown in FIG. 4). ) Is good.

In order to increase the friction coefficient between the second moving sheet 3 and the second moving sheet 3, nylon 402D-
It is exemplified to use a sheet of OX or the like coated with urethane.

In this embodiment, the length of the seat 16 is preferably twice the distance between the support shafts 12 and 13. Further, it is desirable to provide a load sensor (not shown) on the motor so that the motor does not operate when the care-receiver C is not placed on the seat 16.

In order to keep the sheet 16 taut while the sheet 16 is being fed out as described above, both the support shafts 12,
13 motors rotate in synchronization with each other, or
The motor of the spindle 12 on the feeding side is rotated by the spindle 13 on the winding side.
It is advisable to apply back tension such as rotating the motor slightly slower than the motor.

When the care receiver C is placed on the stretcher 1 as described above and the care receiver C is transferred to the intended place and then the care receiver C is returned to the bed, The work may be performed in the reverse order.

It should be noted that, as in the embodiment shown in FIG. 4, a method of performing all the horizontal movement of the care-receiver from the bed to the stretcher by sliding, and the method shown in FIG. 6 on the stretcher. A method of moving the sheet in the horizontal direction by using the unwinding or winding of the sheet by rotating the support shaft may be appropriately used in combination.
