Description

  The present invention relates to an oscillating nursing bed apparatus that can easily prevent a care recipient from rubbing the floor.

  The present inventor has been unable to sleep on his back almost 20 years ago, and cannot sleep unless he is always left or right sideways. After that, when I slept on the bed about 6 years ago, I suddenly thought that it would be the same as hitting the bed if I tilted the bed to the left and right. As a result, I succeeded.

At first, I thought that the bed would not be effective unless it was tilted by 80 to 90 degrees, but it turned out that if the bed was tilted around 30 degrees, the effect would be the same as if it was turned over while repeating the experiment. It was. In addition, it was found that the time required for the bed to tilt back and forth and return to the original position is approximately 5 minutes.
When the present inventor heard in the hospital, in order to prevent bedridden patients from rubbing the floor, it was said that a few nurses are turning over every 3 hours.
The present invention can eliminate such a burden on a caregiver and is very useful for preventing floor rub of a care recipient such as a bedridden patient.

By the way, what was disclosed by patent document 1 is conventionally known as a bed apparatus for care which makes a care receiver turn over, for example.
This nursing bed apparatus is provided with lift cylinders under the left and right portions of the lift bed on which the mats are laid. The lift bed is lifted horizontally by simultaneously raising the left and right lift cylinders, and the toilet bowl is placed under the lift bed. In addition, the right and left lifting cylinders are lifted by only one side, and the lifting bed is tilted sideways so that the care recipient is turned over.

JP 2009-082388 A

However, although the known care bed apparatus described in the above patent publication is provided with a partition around the lifting bed so that the care recipient can sleep and take a bath, the partition is provided by the care recipient. Since it is low so that it does not hit during bathing, when the lifting bed is tilted, those partitions do not support the cared person, and the cared person slips down to the end of the lifting bed, There is a problem that you will feel the fear of falling from the lift bed.
Therefore, an object of the present invention is to provide a care bed apparatus that allows a care receiver to tilt a bed with peace of mind in order to prevent floor rubbing.

  As a result of earnest research on a technique capable of overcoming the above-described problems of the above-described conventional technology and realizing the above-described object reliably, the present inventor has the following summary configuration. The present invention has been conceived.

That is, the swing type nursing bed apparatus of the present invention is

Wherein on a rocking platform along its longitudinal direction are sequentially respectively supporting head floorboard said swing table is supporting the head of the caregiver in the case of a substantially horizontal direction perpendicular to the longitudinal direction, the A torso floor plate that supports a to- be-cared person's torso when the swing table is substantially horizontal in a direction orthogonal to the longitudinal direction, and a cover to be applied when the swing table is approximately horizontal in the direction orthogonal to the longitudinal direction. A leg floor plate that supports the leg of the caregiver;
Wherein are respectively erected on both ends of the floor plate, the head plate supporting the head of the caregiver when the swing table is inclined sideways in the direction perpendicular to the longitudinal direction, the rocking When the moving table is inclined in the direction orthogonal to the longitudinal direction, the trunk side plate for supporting the to-be-cared person's torso and the swinging table are inclined in the direction orthogonal to the longitudinal direction. a leg side plates for supporting the legs of the care if it is,
A body side plate interval adjusting mechanism that adjusts the interval between the body side plates using a screw mechanism ;
Have a, bed intervals between intervals and the leg side plates of the head plate to each other, that is narrower than the distance between the barrel plate,
The bed is swung laterally around a fixed horizontal axis extending in the longitudinal direction of the swing table, and the swing table is between a substantially horizontal state and a laterally inclined state in a direction perpendicular to the longitudinal direction. a swing mechanism that Ru is swung in,
It is made up of.

According to the swing type nursing bed apparatus of the present invention, the bed has a longitudinal direction substantially head floorboards which are sequentially respectively supported along its length on a rocking platform extending horizontally and the body floor And at least a head, a trunk, and a leg of a cared person lying on his / her back on a bed when the swing base is substantially horizontal in a direction (width direction) orthogonal to the longitudinal direction. In this state , the swinging mechanism swings the bed laterally around a fixed horizontal axis extending in the longitudinal direction of the swinging table, so that the swinging table is orthogonal to the longitudinal direction. Since the head floorboard, the trunk floorboard, and the leg floorboard are tilted to the left and right, for example, about 30 degrees, the cared person turned over. As in the case of the caregiver, it has the effect of moving the pressed part of the caregiver to the opposite side. It is possible to effectively prevent the person of pressure sores. Of course, the cared person may actually turn over by helping the bed tilt.

Moreover, according to the swing type nursing bed apparatus of the present invention, the bed is swung and the swing base is tilted laterally in the direction (width direction) perpendicular to the longitudinal direction thereof, so that the head floor plate, the trunk floor plate and the legs are tilted. When the head and floor boards are tilted sideways, the distance between the head side boards standing on both side edges of the head floor board and the distance between the leg side boards standing on both side edges of the leg floor board are The head side plate erected on both sides of the floor plate is narrower than the space between the side plates of the body plate standing on both side ends of the body floor plate. Supporting the head, the trunk side plates erected on both sides of the trunk floor slab supported the torso of the cared person lying on his back on the bed, and erected on both sides of the leg floor slab leg side plate supporting the legs of the care who lay on his back on the bed, the spacing of the body side plates for supporting the torso of particular weight, using a screw mechanism Adjustable to fit the width of the torso by the side plate spacing adjustment mechanism, the cared person does not fall off the bed, so the cared person can rest in bed without fear of falling from the bed Can be tilted.

Incidentally, in the swing type nursing bed apparatus of the present invention, the body portion is connected swingably to the bed is located on both outer sides of the side plate, between the barrel plate and the head plate, wherein When an edge plate is further provided to support the arm portion of the cared person that is exposed from the gap in the longitudinal direction of the rocking base (6) , the edge plate is used when the bed is tilted horizontally. This is preferable because the part is supported.
Further, in the swing type nursing bed device of the present invention, further comprising an edge plate posture maintaining mechanism that moves the edge plate in parallel with the swing of the bed and maintains a substantially horizontal constant posture. When the head floor plate, the trunk floor plate, and the leg floor plate are inclined sideways, the edge plate supports the arm portion more reliably, which is preferable.

Here, the edge plate posture maintaining mechanism may use a parallel link connected to one end of the edge plate and a horizontal movement guide mechanism for guiding the horizontal movement of the other end of the parallel link. In addition, both the vertical movement guide mechanism that guides the vertical movement of the support rod coupled to the edge plate and the horizontal movement guide mechanism that guides the horizontal movement of the vertical movement guide mechanism are both edges. This is preferable because the plate can be moved in parallel with the swing of the bed and maintained in a substantially horizontal and constant posture.
Furthermore, in the swing type nursing bed apparatus according to the present invention, when the bed further includes a head side plate interval adjusting mechanism that adjusts the interval between the head side plates using a screw mechanism , This is preferable because the distance can be adjusted to the height of the head when the bed is inclined by the head side plate distance adjustment mechanism.

Then, the swing type nursing bed apparatus of the present invention, the swing mechanism, when those having electrically controlled drive operable switch, that you install the switch at hand of the caregiver Then, when the cared person feels that the floor is rubbing, he / she switches on himself and tilts the bed, and when the tilt angle of the bed reaches the cared person's favorite angle, he / she switches off the bed This is preferable because it can be stationary.

Further, the swing-type nursing bed apparatus of the present invention, the swing mechanism, when those having a human power driving device inputted human power via a speed reduction mechanism, due to cost reductions and energy saving nursing bed Is preferable.

Further, the swing-type nursing bed apparatus of the present invention, the swing mechanism, while being driven by the operable electrically controlled drive switch, intended to be driven even by human power through the speed reduction mechanism by the switching It is preferable for an emergency such as a power failure.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. Here, FIG. 1 is a plan view showing an embodiment of the swing type nursing bed apparatus of the present invention with a part omitted, and FIG. 2 shows the section of the swing type nursing bed apparatus of the above embodiment. FIG. 3 is a plan view showing the trunk side plate interval adjusting mechanism and the head side plate interval adjusting mechanism of the swing type nursing bed device of the above embodiment, FIG. FIG. 5 is a side view showing the body side plate spacing adjustment mechanism and the edge plate posture maintaining mechanism of the swing type nursing bed apparatus of the above embodiment, and FIG. 5 shows the swing type nursing bed apparatus of the above embodiment. 1 is a front view showing an inclined state, in which 1 is a bed extending in a substantially horizontal direction, 2 is a rectangular frame-like base, 3 is a gate erected on both short sides of the base 2 The column of the mold (the front side is not shown), 4 is attached to both ends of the bed 1 in the extending direction so as to support the bed 1 A support shaft 5 and a support shaft 4 are rotatably supported on the upper end of the column 3 so as to support the bed 1 so as to be swingable in the horizontal direction about the horizontal axis extending in the longitudinal direction. Each provided bearing is shown. Moreover, the code | symbol P shows a care receiver.

The bed 1 here has two girders 6 connected to each other by a plurality of beams (not shown) to form a ladder-like swing base, and two trunk floor plates are placed on the two girders 6. The trunk | drum floor board 7 which is one of these is slidably passed. Reference numeral 8 denotes another trunk floor board slidably stacked on the trunk floor board 7. 9 when viewed bed 1 from the foot back side of the care P in the direction of the head, the left end of the barrel floor 7, a barrel plate which projects upward, body portion side plate 9 is shorter than the trunk | drum floor board 7, and is formed in the state which opened the pillow side partly. Also, a trunk side plate 10 shorter than the trunk floor plate 8 is projected upward at the right end portion of the trunk floor plate 8, and the trunk side plate 10 is also partially opened on the pillow side. It is formed in the state. The reason is that when the trunk side plates 9 and 10 are formed with the same length as the trunk floor plates 7 and 8, the cared person P enters the box and feels very cramped. Therefore, in this embodiment, in order to solve the above-described problem, the trunk side plates 9 and 10 are shortened, and the trunk side plates 9 and 10 and the head side plates 54 and 56 described later are interposed. The gap is sufficiently opened so that the cared person P can get his arm out of the gap.

Further, the leg floor plate 11 is fixed by passing the leg floor plate 11 on the two girders 6 on the leg side from the trunk floor plate 7, and the leg side plate 12 is protruded upward on both side ends of the leg floor plate 11. is doing.
Furthermore, in this embodiment, a plurality of bolts 13 are provided to project downward from the lower surface of the head floor plate 50 and the leg floor plate 11 described later of the bed 1 or the beam, and the heads are connected to the plurality of bolts 13. Two adjusting members 14 positioned below the floor plate 50 and the leg floor plate 11 are fixed from above and below using nuts 15, and the axis of a connecting shaft 30 described later of these adjusting members 14 is The bed 1 is configured to be positioned below a straight line connecting the two support shafts 4 provided at both ends of the bed 1.

  Further, two pedestals 16 are installed on the base 2 which is in a lateral position substantially opposite to these adjusting materials 14, and bearings 17 are fixed to the pedestals 16. The shaft 20 having one end fixed thereto is rotatably supported.

Further, in this embodiment, a sprocket 21 is fixed to an intermediate portion of a shaft 20 that rotates the crank 18, and a sprocket 23 fixed to the sprocket 21 and an output shaft of a worm gear mechanism type speed reducer 22 provided on the base 2. A controller (not shown) having a switch for operating and stopping the electric motor by winding the chain 24 around the shaft and connecting the output shaft of an electric motor (not shown) as an electrically controlled drive device to the input shaft of the speed reducer 22 In the bed 1, it is placed within the reach of the care recipient P or the attendant caregiver.

  Each adjusting member 14 is applied with two plate members constituting the rod 29 so as to be sandwiched from both sides of the adjusting member 14, one end of the rod 29 is connected to the adjusting member 14 by a connecting shaft 30, and the other end of the rod 29 is connected. A shaft hole is formed in the portion, one end portion of the turnbuckle 31 is sandwiched between two plate materials of the rod 29, and one end portion of the turnbuckle 31 is fixed to the hole formed in the rod 29 with a bolt 32. And the other end part of the turnbuckle 31 is connected with the other end part of the crank 18 with the axis | shaft 33, and the rocking | fluctuation mechanism is comprised.

  When the care receiver P or an accompanying caregiver who has received the instruction operates the switch of the controller to rotate the output shaft of the electric motor by the swing mechanism configured as described above, the rotation of the output shaft causes the operation sound to rotate. The speed is reduced as appropriate by the quiet worm gear mechanism type speed reducer 22 and is transmitted from the speed reducer 22 to the crank 18, whereby the crank 18 continuously rotates and pushes the adjusting material 14 via the turnbuckle 31. At the dead center position where the crank 18 is rotated approximately 90 degrees to the left and right from the vertical position, the bed 1 is tilted to an arbitrary angle, for example, about 30 degrees in the lateral direction.

  It should be noted that the height of the adjusting material 14 provided by a plurality of bolts 13 provided on the lower surface of the bed 1 is such that the cared person complains of pain when the bed 1 is tilted greatly due to the medical condition of the cared person. In this case, the maximum inclination of the bed 1 can be reduced by turning the nut 15 away from the bed 1 and the cared person who prefers to greatly tilt the bed 1 is provided with a plurality of bolts 13. This is because the maximum inclination of the bed 1 can be increased by turning the nut 15 screwed into the bed to bring the adjusting material 14 closer to the bed 1.

  In addition, the reason that the turnbuckle 31 is provided and the turnbuckle 31 is turned so that the adjusting member 14 is brought close to or away from the crank 18 is that the bed is left on the left side depending on the medical condition of the cared person. If 1 is tilted greatly, the pathological condition will be disturbed, and the adjusting material 14 is moved closer to the crank 18 to reduce the maximum tilt of the bed 1 to the left, and if the bed 1 is tilted significantly to the right, the pathology This is because the maximum inclination of the bed 1 to the right can be reduced by moving the adjusting member 14 away from the crank 18.

The electric motor basically only needs to rotate in one direction, but it may be forward / reversely rotated by the operation of the switch. In this case, when the inclination angle is too large, By making it reverse, the inclination angle can be reduced immediately.
In this embodiment, an edge plate 36 on which the arm portion of the cared person is placed using a plurality of hinges 35 is swingably provided on the outer side surfaces of the trunk side plate 9 and the trunk side plate 10.

In this embodiment, a plurality of bearings 37 are provided at arbitrary positions on the lower surface outside the edge plate 36 so that the edge plate 36 always maintains a substantially horizontal constant inclination angle regardless of the angle of the bed 1. projecting, on the other hand, the base 2 passes a plurality of rails 38, a plurality of rollers 39 rolling on the upper and lower surfaces of the rails 38, and the axial wear with the axis 41 to the plate 40 A horizontal movement guide mechanism is formed, and a bearing 42 is projected upward in the middle of a plate 40 provided so as to sandwich the roller 39 from both sides. Each of the bearings 37 and the bearing 42 are connected using a shaft 44 to constitute an edge plate posture maintaining mechanism.

With the edge plate posture maintaining mechanism as described above, the edge plates 36 on both sides can always maintain a constant angle regardless of the direction in which the bed 1 is inclined. This structure refers to a wiper of a large truck or a large bus, and the two rods 43 constitute a parallel link.
In the present embodiment, as described above, the edge plate 36 remains almost horizontal regardless of the direction in which the bed 1 is tilted. Therefore, it is very easy for the cared person to place his / her arm on the edge plate 36.

Further, in this embodiment, the distance between the trunk side plate 9 projecting from the left end of the trunk floor plate 7 and the trunk side plate 10 projecting from the right end of the trunk floor plate 8 superimposed on the trunk floor plate 7. In order to always adjust the length to match the physique of the cared person, leave a certain distance in the center of the two girders 6, and adjust the screw direction on the left and right so that the left side is left and the right side is right Two screw shafts 45 formed differently are provided so as to pass through, and a portion between the two beams 6 of the two screw shafts 45 is arranged so that the screw shaft 45 does not shift laterally.

Further, since the worm gear mechanism is used as the speed reduction mechanism, the bed 1 can be stopped at an arbitrary inclination angle without particularly fixing the handle 102 with a stopper or the like.

While the present invention has been described based on the illustrated examples, the present invention is not limited to the above-described examples, and can be appropriately changed within the scope of the claims. For example, the swing mechanism may be an electric motor or a hydraulic pressure. An electric control type driving device that swings the bed 1 with a cylinder and a human power type driving device that swings the bed 1 manually through a speed reduction mechanism are configured so that they can be switched and connected by a coupling or the like. Also good.

The swing mechanism is intended instead of hydraulic cylinders, may be used in an electrically controlled drive Pneumatic cylinder for pneumatically operated from the compressor, etc., in this case, the switch that controls the operation of the electric motor of the compressor Alternatively, an operation of an on-off valve provided in the pneumatic circuit may be controlled.

Further to the controller, the electrically controlled drive device provided with a timer or microcomputer controls the switch actuating the start time and end time of the operation of inclining to the right or left bed 1 from the horizontal state, yet their inclined state In addition, the horizontal holding time may be set.
Further, the speed reduction mechanism of the electric control type driving device or the manpower type driving device may be provided with a normal gear set or a belt type transmission mechanism and a stopper which is releasably latched. The screw mechanism of each interval adjusting mechanism may be driven by a motor.

Further reduction mechanism manpower driving device is in place of or in addition to the handle, it may be driven for example by a pedal foot踏式as a bicycle.
Further, the edge plate may be fixed to the trunk side plate and rocked integrally with the bed 1, or may be omitted if the cared person puts both arms inside the trunk side plate.
Further, in order to prevent the cared person from falling from the bed 1 more reliably when the bed 1 is tilted, a safety belt may be provided between the upper ends of the both body side plates, or the upper ends of the both body side plates. The part may be curved slightly inward.
Furthermore, in order to facilitate the defecation processing and urination processing of the cared person on the bed 1, an opening may be provided in the base of the trunk side plate, etc., and the trunk side plate can be folded with a hinge or removable. Or you can do it.

Thus, according to the swing-type nursing bed apparatus of the present invention, the bed has a longitudinal direction substantially turn each supported head floor and the body in its longitudinal direction on a rocking platform extending horizontally When the swing board is substantially horizontal in the direction orthogonal to the longitudinal direction , the floor board and the leg floor board respectively support at least the head, trunk, and legs of the care recipient who lies on his back on the bed. In this state , the swing mechanism swings the bed laterally around a fixed horizontal axis extending in the longitudinal direction of the swing base, and the swing base is substantially horizontal in a direction orthogonal to the longitudinal direction. The head floorboard, the trunk floorboard, and the leg floorboard are tilted horizontally, for example, to about 30 degrees, so that the cared person rolls over. Has the effect of moving the care recipient's pressed area to the opposite side, It is possible to prevent the bedsore effectively. Of course, the cared person may actually turn over by helping the bed tilt.

In addition, according to the swing type nursing bed apparatus of the present invention, the bed is swung to tilt the swing base horizontally in the direction perpendicular to the longitudinal direction, and the head floor plate, the trunk floor plate, and the leg floor plate are combined. When tilted horizontally, the distance between the head side plates standing on both side ends of the head floor plate and the distance between the leg side plates standing on both side ends of the leg floor plate are determined by the trunk floor plate. The head side plates erected on both side edges of the floorboard support the head of the cared person lying on his / her back on the bed. The torso side plates erected on both ends of the torso floor plate support the torso of the cared person lying on his back on the bed, and the leg side plates erected on both end portions of the leg floor plate are supporting the legs of the care who lay on his back on the bed, in particular a spacing of the body side plates for supporting the barrel with a weight, between barrel plate using a screw mechanism The adjustment mechanism can be adjusted to fit the width of the torso, so that the cared person will not fall off the bed, so the cared person can tilt the bed with peace of mind without fear of falling off the bed Can do.
