DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, the nursing mattress of the present invention will be described in more detail based on examples.
FIG. 1 is a side view of the use condition of the care mat of the present invention as seen from the direction of the head of the cared person, and (a) is a diagram showing the condition where the cared person is sleeping in the center of the comforter 1 (B) is a diagram showing a state in which the cared person is turned sideways, and (c) is a state in which the cared person in the state where the mattress 1 is rotated and turned sideways is moved to the center. It is a figure which shows a state. FIG. 2 is a plan view showing a use state of the nursing mattress of FIG.
[0012]
The mattress 1 of the present embodiment has a crushed cylindrical shape. In FIG. 1, rotating bars 2 and 2 are installed along the inner side of the left and right folded portions of the mattress 1. On the other hand, the drive shafts 3 and 3 are arranged along the width direction of the mattress 1 at both ends in the rotational center direction of the mattress 1. The drive shafts 3 and 3 are connected to both ends of the rotation rods 2 and 2 in the rotation center direction . The drive shaft 3 is provided with a worm gear, the rotary rod 2 is provided with a worm, and the worm gear and the worm are engaged with each other. Thereby, the rotation of the drive shaft 3 is transmitted to the rotating rod 2.
[0013]
The drive shafts 3 and 3 are connected to drive units 4 and 4 made of a motor or the like. In addition, this drive part 4 and 4 is installed in the width direction center of the mattress.
The drive shaft 3 is rotated by the operation of the drive unit 4, and the rotating rod 2 is rotated accordingly. At this time, both the rotating rods 2 and 2 are simultaneously rotated in the same direction. Thereby, the mattress 1 rotates in the entire circumference rotation direction . Moreover, when the drive shaft 3 and the rotating rod 2 are configured to be detachable, the drive unit 4 and the drive shaft 3 can be detached when not used for driving. In addition, it is possible to drive only one of the driving units 4 and 4 arranged at the center in the width direction of the mattress 1 and to make the other idling type.
[0014]
The inner peripheral surface 1a of the mattress 1 is covered with a sheet that is lubricated with a fluororesin or the like. On the other hand, the drive shaft 3 is subjected to a process for increasing the frictional resistance with the inner peripheral surface 1 a of the mattress 1.
[0015]
The mattress 1 is laid on a crushed cylindrical auxiliary futon 10. The auxiliary futon 10 is wider than the width of the mattress 1. In addition, the inner peripheral surface 10a of the auxiliary futon 10 is subjected to a lubrication process.
[0016]
Next, a method of using this nursing mattress will be described.
First, the auxiliary futon 10 is laid, and the mattress 1 is laid in the center of the auxiliary futon 10 in the width direction. And as shown to Fig.1 (a), the cared person 20 is made to lie in the center of the mattress 1 on its back. Then, for example, the cared person 20 is turned to the left or right every two hours. FIG. 1 (b) shows a recumbent state turned over to the right. At this time, the cared person 20 is located at the end of the mattress 1.
[0017]
In this state, the sleeping comfort is poor, and there is a possibility of falling from the mattress 1, so it is necessary to move the care recipient 20 to the center of the mattress 1. Therefore, by operating the driving unit 4, a drive shaft 3 is rotated, the rotation rod 2 is rotated, mattress 1 with the rotation of the rotating rod 2 starts to rotate the entire circumference direction of rotation, and FIG. 1 (b) , The mattress 1 rotates counterclockwise. When the cared person 20 is arranged at the center of the mattress 1 as shown in FIG. 1 (c), the drive unit 4 is operated to stop the rotation of the drive shaft 3 and the rotating rod 2.
[0018]
Then, after two hours have passed, the cared person 20 can be placed in the center of the mattress 1 by laying the cared person 20 on his back again and rotating the mattress 1 clockwise.
[0019]
Similarly, when turning to the left, if the driver 4 is operated, the drive shaft 3 is rotated, the rotating rod 2 is rotated, and the mattress 1 is rotated clockwise, the cared person 20 is moved. It is possible to lie down in the center of the mattress 1 while lying on the left side.
In this manner, the cared person 20 can always be placed at the center of the mattress 1 by sequentially rotating the mattress 1 clockwise and counterclockwise.
[0020]
When the mattress 1 rotates, the auxiliary futon 10 laid under the mattress 1 also rotates. At this time, since the upper surface 10b of the auxiliary futon 10 is shifted, the mattress 1 can rotate smoothly. Moreover, when the upper surface 10b of the auxiliary futon 10 is displaced, the mattress 1 laid on the auxiliary futon 10 can rotate in the rotation direction at the fixed position without moving. That is, the mattress 1 can be rotated in the same space.
[0021]
Figure 3 is a side view of a use state of use as viewed from the direction of the head of the care in the bed a nursing mattress of the present invention, (a) is the caregiver sleeping in the middle of the mattress 1 (B) is a diagram showing a state in which the cared person is turned sideways, and (c) is a figure in which the cared person who has turned the mattress 1 sideways is placed in the center. It is a figure which shows the state which moved to. FIG. 4 is a plan view of a state in which a nursing mattress is used on a bed.
[0022]
When used in the bed 15, the left and right ends of the auxiliary futon 10 hit the frames 16, 16 on the side of the bed 15, and are bent slightly upward. And the mattress 1 should just be laid on it. The method of use is the same as before.
When used in the bed 15, the driving unit 4 on the head side of the cared person 20 is supported by the frame of the bed 15 through the headboard 17 or the like, and the driving unit 4 on the foot side passes through the footboard 18 or the like. Supported by the frame.
[0023]
In addition, you may give the flexibility to the rotating rods 2 and 2 so that it may respond | correspond to the time of the bed 15 being gagged. Further, by making the outer diameter dimension of the central part of the rotating rods 2 and 2 larger than the outer diameter dimension of both end parts, the positional relationship with the mattress 1 during rotation (mismatch) may be prevented. .
[0024]
When the mattress 1 is used, as shown in FIG. 5, the inner surfaces of the upper and lower sides (upper surface 1b and lower surface 1c) of the mattress 1 and the inner surfaces of the upper and lower sides (upper surface 10b and lower surface 10c) of the auxiliary futon 10 are in contact with each other. Is expected. However, since the inner peripheral surface 1a of the mattress 1 is covered with a sheet that has been subjected to a sliding process with a fluororesin or the like, even if the upper and lower surfaces 1b and 1c come into contact with each other, it may interfere with the rotation of the mattress 1. It rotates smoothly. Further, since the inner peripheral surface 10a of the auxiliary futon 10 is also lubricated, it rotates smoothly without hindering rotation.
[0025]
Further, when the floor surface is slippery or when the floor surface is wide, the auxiliary futon 10 need not be used. Further, the mattress 1 may be rotated by manually pulling a handle (not shown) attached to the mattress 1 without using the driving unit 4. At this time, the mattress 1 may be rotated with the rotating rod 2 removed.
[0026]
Furthermore, in the said Example, although the care receiver 20 was described regarding the state of the recumbent about 90 degrees sideways, the width | variety of the auxiliary | assistant futon 10 was made necessary amount wide, and the care receiver 20 was rotated about 180 degrees. It can be used pronely in prone position therapy.
[0027]
Usually, it is necessary to be careful not to drop the caregiver from the mattress 1 to make the caregiver in a prone state. But it's not easy. In addition, since the work is quite physical, caregivers have to spend a great deal of labor.
[0028]
However, according to the mattress 1 , even if the cared person 20 is rotated in a lying or prone state, the cared person 20 can always be arranged in the center of the mattress 1 by rotating the mattress 1. Since it is possible, even if there is only one caregiver, it is possible to make the cared person 20 in a prone state.
[0029]
In the present embodiment, the substantially cylindrical futon 1 and the auxiliary futon 10 are arranged in two stages up and down and laid in a shape of approximately 8, but the auxiliary duvet has two stages and the substantially tubular futon 3 It can also be set as the structure arranged in steps.
[0030]
By the way, every time the cared person's back is raised several times a day for meals, rehabilitation, etc., the cared person's body has moved in the direction of the feet. Therefore, the caregiver needs to hold the cared person in the direction of the head and move it, and it has been hard labor as when turning over.
[0031]
Therefore, the method of laying the cared person in the direction of the center of rotation of the substantially cylindrical mattress 1 and moving the cared person 20 to the left and right has been described above, but as shown in FIG. 6, the width direction (the rotation direction of the mattress 1). It is good also as a structure which makes the care receiver 20 sleep. In this case, since the cared person 20 is laid down along the width direction, it is preferable to form a mattress that is elongated in the width direction. By rotating the mattress 1 in the direction of the center of rotation of the cared person 20, the cared person 20 can always be laid down in the center of the direction of the center of rotation of the mattress 1.
[0032]
Further, in order to raise the back of the care recipient 20, an inclined pile is provided on the inner peripheral surface 1a of the mattress 1 so that the upper surface 1b and the lower surface 1c of the mattress 1 do not slip when the mattress 1 and the auxiliary futon 10 are tilted. Also good. In FIG. 6, an inclined pile 40 facing obliquely downward to the right is provided on the inner peripheral surface 1 a on the upper surface 1 b side of the mattress 1, and an inclined pile 41 facing obliquely upward on the left is provided on the inner peripheral surface 1 a on the lower surface 1 c side.
[0033]
As a result, when the mattress 1 is rotated in the direction of the head of the cared person 20, the mattress 1 rotates smoothly, and the weight of the cared person 20 may cause the mattress 1 to slip down in the direction of the feet of the cared person 20. The inclined piles 40 and 41 are difficult to slip and fall off.
Similarly, an inclined pile may be provided on the inner peripheral surface 10 a of the auxiliary futon 10.
[0034]
The nursing mattress of the present invention is not limited to the configuration of the above embodiment, and can be changed as appropriate. For example, the mattress 1 may be an air mat used for preventing a floor slip or the like, and the method for rotating the mattress 1 may be a method other than the above. In addition, the inner peripheral surfaces of the mattress 1 and the auxiliary futon 10 may be made of a material that is originally excellent in lubricity, such as a fluororesin, without being lubricated. Further, in the above embodiment, the mattress 1 is rotated after the cared person 20 is in a state such as lying or lying on the bed, but first, the mattress 1 is rotated and the cared person 20 is placed on the side. Needless to say, the mattress may be used for both the bed and the stretcher when moving from the bed to the stretcher or the like with the heel of the back.
[0035]
