BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for caring for people who are bedridden or bed-ridden because they are difficult to walk, that is, for cared persons. The present invention relates to a care device that can be moved to a desired position and, if necessary, can take a bath.

[0002]

2. Description of the Related Art A lot of labor is required when a so-called bedridden person is moved and cared for from a bed to a bathtub, a toilet, a wheelchair or any other desired position. Furthermore, when taking care of such people in a bath, more labor and, in some cases, special equipment are required.

Until now, a wheelchair has been generally used as a mobile nursing device, and as a special device, a rail is attached to a ceiling portion of a house from a bed portion to a predetermined portion, and a hammock is hung on the rail. Devices for mobile nursing care are known. Similarly, as a bathing care device, there is a device in which a rail is provided on a ceiling of a bathroom and a hammock is movably suspended on the rail.

However, there has been no device which has both a mobile care device and a bathing care device until now.

DISCLOSURE OF INVENTION Problems to be Solved by the Invention
In particular, moving care using rails fixed to the ceiling requires a large amount of cost for improving the house itself and installing the rails, and the moving place is limited, and there are many problems in safety and operability. It is piled up. This is the same when used as a bathing care device. In addition, such a device requires a considerably large area and various equipments attached thereto, and is not yet widely used in general households. In addition, many volunteers are required to operate these care devices, which cannot be used at all when one needs to care for himself at home.

Therefore, according to the present invention, in order to solve such a problem, a bedridden person can be moved to a predetermined position by a simple operation, and one caregiver can safely take a bath in a bathtub at home. The present invention provides a nursing care device that can be operated.

[0007]

The present invention eliminates the need for mounting rails or the like, and causes a bedridden caregiver to safely lift with only one hand and maintain balance in a simple manner to cause a fall. There is provided a balanced type nursing care device with which a cared person can be carried to a desired position by a method similar to that of a known wheelchair, and gently lowered into a bathtub as required to take a bath.

In order to safely and easily lift a bedridden caregiver by one caregiver and move it to a predetermined position, and further, for example, to put it in a bathtub, the care apparatus of the present invention is moved for transfer. Means, a lifting means having a harness for wrapping and lifting the care-receiver, and position adjusting means for safely adjusting and operating the position of the lifting means. A chain block and a switch for operating the chain block are provided to safely lift a care receiver wrapped in a harness. An adjusting weight is provided so that the moving means does not fall down during lifting. Further, a carrier for attracting the cared person to the vertical column and a rope for operating the cared person are provided so that the cared person does not swing while moving.

In order to enable bathing care, the care receiver can be moved outside the range of the dolly of the present device by adjusting the adjusting weight.

DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described with reference to FIGS. Balanced lift care device 9 of the present invention
Reference numeral 0 is composed of a moving means 1, a position adjusting means 91, and a lifting means 92.

The moving means 1 is specifically composed of a movable carriage. This trolley has a base plate 2, a pair of casters 3 supporting the front side of the base plate 2, and a pair of wheels 4 supporting the rear side of the base plate 2.

Two holes are drilled in the vicinity of the right end of the base plate 2 in FIG. 1, and two horn support rods 29 and 30 are mounted in the holes. As shown in FIG. 2, the diameter of the portion of the strontium support rods 29, 30 above the upper edge of the base plate is preferably larger than the diameter of the portion below the upper edge of the base plate. This is an adjustment squirrel 35 described later.
This is so that the can be easily attached and detached. Reference numeral 31 is a fixed horn fixed to the lower part of the base plate. The fixed weight 31 is provided with two holes, and the cradle support rods 29 and 30 pass through the holes. Threaded portions are provided on the lower portions of the cradle support rods 29 and 30, and the fixed weight 31 is firmly fixed to the base plate by nuts 32 and 33 that are screwed together. 34

Reference numeral 35 is an adjusting stool placed on the upper part of the base plate, and holes having a diameter slightly larger than the diameters of the two strontium supporting rods are drilled. . Reference numeral 36 is a hand push rod whose lower end is fixed to the base plate 2.

The position adjusting means 91 is generally made of a non-deformable material such as steel and the like, and the frame 2
And a position adjusting mechanism 25 attached to 0.

The frame 20 is attached to the moving means 1 and extends upward from the vertical column 5, and the horizontal column 6 is attached to the vertical column 5 and extends laterally therefrom.
have. The horizontal pillar 6 has a load pillar 7 extending forward from the vertical pillar 5 and an operation pillar 8 extending rearward from the load pillar 7.

The position adjusting mechanism 25 has a function of adjusting the position of the lifting means 92 in the vertical and horizontal directions. The position adjusting mechanism 25 generally includes two rail receiving fittings 9 fixed to the load column 7, a hanger rail 10 mounted in the rail receiving fitting 9, and a hanger rail 10.
And a carrier 11 which is attached to the carrier 11 and can roll left and right along the horizontal column 6 and is connected to the carrier 11
A well-known electric chain block 12 operated by a 0 volt AC power source, a chain case 13 for accommodating an extra chain, a load chain 14 which is moved up and down by the electric chain block 12, and a chain fixed to the lower end of the load chain. It includes a hook 15, a stopper 21 for preventing the carrier 11 from coming off, a load side pulley 22, an operation side pulley 23, and an operation rope 24. One end of the operation rope 24 is connected to the carrier 11 and is connected to the load side pulley 22.
Then, it is inverted and hangs downward from the operation-side pulley 23, is inverted in a loop shape, rises up again, bends to the left at the operation-side pulley 23, and is again connected to the carrier 11. Reference numeral 26 is a movement switch hanging along the vertical column 5, 27 is a fixed switch fixed to the operation column 8, both of which are switch boxes for opening and closing a power source for adding to the electric motor of the electric chain block 12, Each has two pushbuttons, one for raising and the other for lowering, operating only while pushing the button. The movement switch 26 is mainly a suspending means 92.
The fixed switch is operated by the care giver by the care giver 19 suspended by the care giver.

Reference numeral 28, which is arranged on the base plate 2 of the moving means 1, is a cord box for accommodating a 100-volt power cord, which is pulled out as necessary to be connected to an indoor outlet. In FIG. 1, electrical wiring is omitted.

Further, FIG. 1a shows the distance between the hook 15 and the left end of the base plate when the carrier 11 is moved to the left end in FIG. The length of a depends on what the device is used for. For example, when the width of the bathtub is 1 m, a is usually 50 cm, which is half the width. b is the distance between the lower end of the caster 3 and the vertical column. The length of b is about half the shoulder width of the cared person.

The suspending means 92 is a means for suspending the cared person 19 from a bed or the like, and the hook 15
The horizontal bar 16 mounted on the vehicle, the harness support fittings 17 fixed to both ends of the horizontal bar 16, and the harness 18 for supporting the care receiver 19. The harness 18 and the harness support fitting 17 are easily attached and detached. ing. As a result, by pushing the harness 18 under the body of the care receiver 19 on the bed in advance and then mounting the harness 18 on the harness support fitting 17, the care receiver 19 can be easily operated by one care worker.
Can take care of.

Next, a method of using the device 90 will be described. FIG. 1 shows the cared person 19 lifted from a bed or the like. The weight and the like of the cared person 19 generate a moment to rotate the device 90 counterclockwise about the contact point P between the caster 3 and the bed. What balances this is the fixed slag 31 and the adjustment slag 35 that increases or decreases the number depending on the weight of the cared person 19. When the cared person 19 is lifted, the carer grasps the push rod 36 and puts both feet on the footboard 34.
It is possible to increase the clockwise moment that opposes the moment by mounting on the. The adjustment horn 35 is preliminarily attached only for compensating for this shortage of the clockwise moment. Next, the caregiver operates the fixed switch 27 in this state to slowly lift the care receiver 19 safely protected by the lifting means 92 upward from the bed or the like.
After that, the caregiver pulls one of the loops of the operation rope 24 to draw the care receiver 19 toward the vertical column 5, and finally the part of the body of the care receiver 19 is brought into light contact with the vertical column 5. This is to prevent the cared person 19 from swinging back and forth and left and right in a suspended state, and to reduce the counterclockwise moment as much as possible to prevent the occurrence of falls. The end of the operating rope 24 can be wound around the end of the horizontal column 6 several times. In this state, the counterclockwise rotation moment applied to the device 90 is reduced. Therefore, in such a state, the adjustment weight 35 is installed in advance so that the device 90 does not fall down even if the caregiver gets off the step board 34. In this state, the device 90 is moved to a desired position, for example, a bathtub, a toilet or a wheelchair.

After moving to the predetermined position, the caregiver rests on the footboard 34 and pulls the other of the operation rope 24 to separate the care receiver 19 from the vertical column 5 and slowly lowers the care receiver 19.

If the care receiver 19 is to be bathed,
It is preferable to remove the clothes in advance before placing the care receiver 19 on the harness 18 of the lifting means 92. Then, after the cared person 19 is transferred to the bathroom, the cared person again mounts on the footboard 34 and pulls the other side of the operation rope 24 to separate the cared person 19 from the vertical column 5 and position the cared person directly above the bathtub. After that, the fixed switch 27 is pushed to slowly lower the care receiver and put it in hot water. After that, the caregiver leaves the tread 34 to take care of the care receiver. When taking care of such a bath, the adjustment weight 35 is sufficiently used in order to give top priority to the safety of the fall prevention.

Generally, when the cared person 19 is lifted and moved, the cared person swings greatly, so that the direction of gravity particularly acting on the cared person 19 falls within the area occupied by the moving device 1. If not, there is a risk that the device 90 may fall due to the swinging movement. However, in this device, since the care receiver 19 is in contact with the vertical column 5 during moving care, the swinging is small, and the direction of gravity acting on the care receiver 19 is within the area occupied by the carriage. Moreover, since the caregiver holds the push bar 36 behind the device 90, there is no risk of falling. In addition, for example, when bathing and caring for the care receiver 19, if the direction of gravity acting on the care receiver 19 is within the range of the device 90, sufficient care cannot be provided, and thus care is usually taken outside the range. The direction of gravity acting on the person 19 moves. However, in this device, such a state occurs when the device 90 is stationary, and in that case,
Since the adjusting weight 35 is in a state of being perfectly balanced with the gravity acting on the care-receiver 19, there is no danger of falling.

The electric chain chain block 12 is preferably battery powered. In the case of the manual type, the manual type may be used when the cared person cannot lift the cared person while riding on the footboard 34, but the cared person himself / herself can operate the chain chain block.

In the apparatus of FIG. 1, the load column 7 projects from the surface occupied by the carriage 1 by a length a. For this reason, for example, when the care receiver 19 is put on the device 90 and moves from the home bedroom to the bathroom, it may not be possible to successfully pass through the corner of the corridor. In order to prevent this, for example, the horizontal column is composed of an interior portion and an exterior portion, the above-mentioned protruding portion is used as the interior portion, and the interior portion is inserted into the exterior portion as necessary, or the protruding portion is It is conceivable to make it possible to rotate it by approximately 180 degrees. 3 to 7 show an example of a specific mechanism of the latter means. FIG. 3 is almost the same as FIG. 1, but in comparison with FIG. 1, parts that are not necessary for this explanation are omitted. 60 is a horizontal pillar. The horizontal pillars 60 are connected by a block A, and only the left side portion of the block A can be bent. 61 is a rotating horizontal column, 62 is a fixed horizontal column, and 63 is a rotating shaft. Rotating horizontal pillar 6
It is assumed that 1 rotates about the rotary shaft 63 as shown in FIG. Reference numeral 64 denotes four rail receiving fittings, which are fixed to the side surface of the horizontal column 60, for example, at the positions shown in FIG. There are two hanger rails 65 on the left and right of the block A, and the orbits of the carriers are the same on the block A. In FIG. 3, the rotating horizontal column 61 and the fixed horizontal column 6
2 uses angle steel. The two 90-degree bent steel plates forming the angle steel are present on the front side and the upper side in FIG. 3 in the fixed horizontal column 62 and on the front side and the lower side in the rotary horizontal column 61. A square connector 66 is fixed to the separated portion of the fixed horizontal column 62, and the rotary horizontal column 61 has a semi-cylindrical steel plate 6 attached thereto.
7 is welded. The square connector 66 is sandwiched between the steel plate on the lower side of the rotary horizontal column 61 and the semi-cylindrical steel plate 67, and the rotary horizontal column 61 is caulked by the rotary shaft 63 so as to rotate smoothly. FIG. 4 is a view in which the rotating horizontal column 61 is rotated about 45 degrees (the adjusting rod 72 and the like described later are omitted in FIG. 4). The rotating horizontal column 61 and the fixed horizontal column 62 are in a straight line or 180
It must be locked and stable in a bent state. A mechanism therefor is shown in FIGS. 5 and 6 (a rail bracket and the like are omitted in both figures). Numerals 70 and 71 are protrusions fixed to a semi-cylindrical steel plate, 72 is an adjusting rod, and 73 is a fixed horizontal column 62

When the rotating horizontal column 61 and the fixed horizontal column 62 form a straight line,
The adjusting rod 72 engages with the projection 70 as shown in FIG. 6, so that the rotating crossbar 61 cannot rotate. When rotating the rotating horizontal column 61, the caregiver pulls the handle 76 at the right end of the adjustment rod 72 to the right to disengage the adjustment rod 72 from the protrusion 70. When locking the rotating horizontal column 61 at the point where it is fully rotated, the adjusting rod 72 and the protrusion 71 may be brought into an engaged state.

Reference numeral 80 is a handle for rotating the drum 79. When the handle 80 is turned, for example, the operation rope 81 wound on the right side of the divided winding portion is wound on the drum 79, and the operation rope wound on the left side is sent out.
The rotation of the drum 79 may be performed by a small motor instead of manually. In this case, if the caregiver previously installs a ridge for generating a balance force for balancing the weight on the moving device 1, most of the above-described operations can be performed only by the careee. Further, when the vertical column 5 is placed right above the rear wheel 4 in FIG. 1, the device 90 can also function as a known wheelchair.

Reference numeral 82 in FIG. 3 is a stool for allowing the cared person 19 to gain weight when the cared person 19 is moved without the lifting means 92.

Next, a second embodiment will be described with reference to FIGS. 8 and 9. 40 is a trolley, 41 is a fixed sledge, 42 is an adjustment sledge, 43 is a vertical column, 44 is a lifting means, 45 is an inclined plate,
