DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention mainly relates to prevention of bedsore when a patient lying on a bed cannot move his / her body freely, and to easily change his or her body position in a treatment accompanying nursing care. The present invention relates to a device for changing the position of a bed that allows the user to do so.

[0002]

2. Description of the Related Art Heretofore, if a patient undergoing medical treatment has long been unable to change his or her body direction while lying on a sickbed, the area subject to compression due to weakness of the body will gangrene,
A so-called bedsore occurs, further depleting the physical strength. For this reason, when a patient cannot move his or her body, a person engaged in nursing care sometimes changes the posture of the patient to prevent the occurrence of a compression region. In addition, when it is difficult for the patient to change his or her body orientation, it is often necessary for the caregiver to change his or her posture during nursing care, such as by wiping the body. Required measures.

[0003] At present, almost all humans are required to change the position of such patients. Therefore, in the case of a patient with a heavy weight, it takes a great deal of effort to move the patient on which one caregiver lies, and it is difficult to frequently change the position of the patient. In particular, in a place where a large number of patients are nursing, such as a hospital, or in a general home that has a patient who has undergone long-term home medical treatment, the labor is a heavy burden.

[0004] For these reasons, it has been known to use an air mat in order to ease the work relying on manual labor. There is also an expensive type in which a water bed is used to actively disperse body pressure.

[0005]

However, when the air mat is used, the sound of the motor for sending air and the sound when air is exchanged impair the silence, causing mental fatigue not only for patients but also for people around them. There is a problem of causing it to wake up. In addition, since the mat cannot be washed, it cannot be kept clean, and there is a hygiene problem.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-described situation, and it is possible to significantly reduce the labor required by humans, and to easily change the position of a patient in a lying position according to the patient's condition. It is an object to provide a conversion device.

[0007]

Means for Solving the Problems and Action / Effect In order to achieve the above-mentioned object, the body position changing apparatus in the bed according to the present invention is provided with sheet holding members at both side positions of the bed. The sheet is spread from the sheet holding body to the other sheet holding body and held, and one or both of the sheet holding bodies are associated with elevating / lowering means capable of ascending / descending at least above the sheet arrangement surface of the bed. It is characterized by the following.

According to the present invention having the above-described structure, both ends in the width direction of the sheets laid on the bed are held by the sheet holding members provided on both sides of the bed, and the sheets are normally placed on the bed. The sheets are held in an expanded state. Then, when one of the elevating means provided in association with one or both of the sheet holding members is operated, the sheet holding member is moved upward from the sheet arrangement surface (laying surface) of the bed. The sheets deployed between the sheet holders are lifted together with the lying patient. On this occasion,
The sheet is slanted and tensioned by raising only one sheet holder on one side. As a result, the patient's body on the sheet is lifted on one side and the posture is changed. Therefore, the patient's body can be moved through the sheets, and the patient can be repositioned without directly moving by hand,
At the same time, there is an effect that the contact pressure on the bed (mat) surface can be dispersed. If you can set the degree of elevation of the sheet holder,
There is an advantage that the degree of repositioning can be adjusted. In addition, since the sheets are lifted from the bed surface, the air permeability is improved, and there is an effect that the occurrence of bed sores can be prevented in combination with the elimination of local pressure on the patient. In addition, when the elevating means is associated with both the sheet holders, the sheet holders are alternately moved up and down left and right, so that the posture can be easily changed to a side having a different direction.

It is preferable that the sheet holding member is installed without being connected to a bed frame. This facilitates the movement of the bed, the transfer of the sheet holder, and the like, and prevents the occurrence of a trouble in the installation. Further, the sheet holding body is preferably connected to a bed frame. In this way, a bed provided with a posture changing function can be made convenient for nursing care at home, for example.

The sheet holding body is erected by a supporting frame, and one of the supporting frames is provided with means for raising and lowering the sheet holding body. Preferably, a member is provided. In this way, the sheet holding body can be stably moved up and down by the support frame, and when the sheet holding body is moved up and down, either the sheet is wound or unreeled at the sheet attaching portion, and the sheet is appropriately tensioned. This has the effect that the body position of the patient lying down by applying force can be positively displaced.

In the present invention, the pair of sheet holders is suspended from a ceiling of the building, and the mechanism for suspending the sheet holders includes the elevating means for the sheet holders. Is good. Such a suspension system does not require a space for arranging a support frame or the like on the floor where the bed is installed, so that there is an advantage that the foot is not obstructed around the bed at the time of nursing care.

[0012] Further, the mechanism for suspending the sheet holding body includes:
Hang the sheet holder with ropes or chains,
It is preferable that the rope or chain can be lifted and lowered by a winding type lifting means mounted on the ceiling. In this case, the sheet holding member is lifted by winding up a required amount of the rope or chain hanging the sheet holding member by the lifting / lowering means, thereby changing the position of the patient lying on the bed by lifting the sheet on one side. Can be performed. When the nursing operation is not required, if the rope or chain is removed from the sheet holding body and rolled up by the elevating means, there is an advantage that the device can be used as a normal bed without removing the device without removing it.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, a specific embodiment of the bed posture changing apparatus according to the present invention will be described with reference to the drawings.

FIG. 1 is a schematic diagram showing one embodiment of a body position changing apparatus in a bed according to the present invention. FIG.
1 shows a plan view of FIG.

The postural change apparatus in the bed according to the present embodiment is mainly used for a nursing bed (hereinafter simply referred to as a bed) used in a general hospital or the like.

The postural change apparatus 1 is provided with supporting frames 13 and 14 which stand close to each other on both sides in the longitudinal direction of the bed 2, and the upper portions of the supporting frames 13 and 14 correspond to almost the entire length of the bed 2. The sheet holders 11 and 12 are arranged in parallel with the bed 2. The sheets 10 are spread and expanded such that the sheets 10 are laid on the bed 2 with the respective ends held between the sheet holding bodies 11 and 12 located on both sides of the bed 2. A support frame 14 supporting one sheet holding body 12 is provided with an elevating mechanism for the sheet holding body 14 (corresponding to an elevating means of the present invention).

The sheet holders 11 and 12 are both supported by support frames 13 and 14 so as to be located slightly lower than the upper surface of the mat 3 of the bed 2. As the sheet holder 11 on the stationary side, a roll (not necessarily a roll) having a length corresponding to substantially the entire length of the bed 2 is supported at both ends by the support frame 13 and is kept in a stationary state. On the other hand, the sheet holder 12 to be moved up and down is constituted by a roll of a required length rotatably supported at both ends by a support frame 14 having an elevating mechanism 18.

The sheet 10 has a width extending from the stationary sheet holder 11 to the movable sheet holder 12 on the movable side with the bed 2 interposed between the sheet holders 11 and 12. Something longer than the bed and having a length corresponding to the length of the bed 2 is used. Needless to say, it is preferable that the dough is a conventionally used sheet fabric or a tougher one. In such a sheet 10, both side edge portions 10a are fixed to the sheet holder 11 on the stationary side.
For example, as shown in FIG. 3, a groove 15 having an appropriate width is provided on the roll surface of the sheet holding body 12 on the movable movable side, and the edge 15 a of the sheet 10 is formed in the groove 15.
Is fixed from the top with a holding metal 16 such as a holding rod and fixed with screws 17, spread over the bed 2 on the mat 3, and expanded.

The support frame 14 of the sheet holder 12 which can be raised and lowered is a direct-acting type such as a hydraulic jack as the lifting mechanism 18.
The sheet holder 12 can be operated at both ends in the axial direction. The lifting mechanism 18 (hydraulic jack) is driven up and down by pressure oil supplied by driving a motor of a separately installed small hydraulic unit (not shown). The rising stroke can be set in a plurality of stages as necessary by controlling the oil amount or setting the position by a limit switch. In addition, a ball screw type, a rack gear type or the like can be adopted in place of the hydraulic jack. In the case of these threaded structures or meshed structures, the amount of movement of the sheet holding body 12 can be set by detecting the amount of movement.

Further, the sheet holding body 12 on the movable side
Although not shown in the drawing, a sheet winding mechanism (for example, a spring-type winding means and a clutch with a brake) is attached to the supporting section, and the fixed sheet 10 is wound and fed to adjust the tension. It is better to be able to.

In this embodiment having the above-described structure, the sheet holding body 12 on the movable side can be moved up and down during use.
When the sheet 8 is operated and raised to a suitable height, the sheet 10 whose edge is fixed to the sheet holding body 12 is lifted on one side as shown in FIG. Can be Then, the patient A lying on the bed 2 can lift a part (one side) together with the sheets 10. At this time, the body position of the patient A changes from the initially lying posture while wearing the medical treatment suit. Also,
When the lifting time of the sheet 10 is maintained at an appropriate amount, the sheet 10 is separated from the mat 3 so that the back side of the patient A is in a state of easy ventilation. After a while, the lifting mechanism 18 is reversely operated to return the sheet holding body 12 to the original position.
The patient A is returned to the bed 2 in a state (position) different from that before the operation by being lowered after being lifted on one side together with the sheet 10. By repeatedly performing such an operation after a lapse of time according to the medical condition, the body posture is changed, a local compressive force is not applied for a long time, and bedsores can be prevented. Similarly, it can be used to turn the body of a patient to wipe it clean. The lifting height of the patient A can be appropriately changed according to the state of the patient.

The sheet holder 1 on the movable movable side as described above.
When the position of the patient A lying on the sheet 2 is changed by ascending the sheet 2, the sheet 10 is naturally tensioned and pulled up. A spring-type winding means and a clutch with a brake) are provided so that when the tension starts to increase, the sheet 10 is appropriately fed so as not to apply an excessive tension to the sheet 10, and the patient A It is possible to prevent a change in body position such as a sudden roll due to a tilt caused by one-sided lifting.

In addition, the patient's posture changing operation by lifting the sheet 10 on one side can be automatically performed at set time intervals by connecting the elevating mechanism 18 to a control mechanism incorporating a timer, for example. Of course, if the procedure is performed automatically under the care of the caregiver, there is an effect that the user is released from heavy labor such as manually moving the patient's body. In particular, if such an automatic operation function is added, the burden of nursing care at night can be reduced, which is more effective.

Further, in the bedsore prevention device 1 of this embodiment,
As described above, since the sheet 10 is detachably attached to the sheet holding members 11 and 12, if the sheet 10 becomes dirty, the holding member is removed from the attachment portion to replace it with a new one. And can be used sanitarily.
