[Object of the Invention]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a care bed for physically handicapped persons such as bedridden elderly people and persons with severe physical disabilities.

[0002]

2. Description of the Related Art Today, with the shift to an aging society, the rapid increase in the number of care recipients such as bedridden elderly people has become a serious social problem. In many cases, these care recipients are incapable of moving themselves, so care is essential, but because of their heavy weight, healthy caregivers are required when changing clothes, bathing or cleaning the body, treating excrement, etc. However, with the progress of the nuclear family, much of the care for these people is actually the labor of a close relative, such as an old wife or old husband who is weakened in physical strength and energy. Depends on. Therefore, many people who have long-term care need to expect the improvement of life-long-term care facilities such as nursing homes, but on the other hand, due to lack of youth workforce and refusal to 3K labor, Since it is difficult to secure human resources such as nurses, nurses, and helpers as personnel in the field, its development has not progressed as late. Therefore, the number of patients per caregiver is increased by improving the care facilities in the facility to develop a care method that is relatively easy, and is hygienic and humanitarian for as many care recipients as possible. It can be said that it is an urgent task to extend the caregiver's hands.

[0003]

Based on the above concept, the present invention has developed a bed dedicated to the care of severely handicapped persons (hereinafter referred to as "patients") such as bedridden elderly and unconscious persons. The important purpose is to solve the problem of the shortage of personnel in facilities for the elderly and hospitals. Secondly, the present invention has an object to provide a care means that can be implemented by simple modification even in a home with a patient.

[0004]

[Means for Solving the Problems] In order to solve the above problems, the present invention provides a bed surface of a bed composed of a large number of unit bed materials along the width direction, and each bed material is used alone or separately. Of the auxiliary bed together with the auxiliary bed of the auxiliary bed to form a complete surface of the bed, and the unit bed of material is at least between the side surface of the unit bed of the adjacent bed or the side surface of the bed of the auxiliary bed. A gist of a nursing bed is that it is provided with a function of raising or lowering so as to form a step so that a heavy fork can enter. Hereinafter, various elements constituting the invention will be described by dividing them into items.

Basic Structure A basic feature of the bed of the present invention is that the bed surface of the bed is composed of a large number of unit beds along the width direction, and a fork for loading a voluntary patient is provided between adjacent bed materials. That is, a space that can be inserted can be formed. Each decubitus material, when the patient is supine or lying down, adjacent unit decubitus materials are close to each other to form a single flat decubitus surface, but a bath,
When the patient needs to be weighed from the bed for the purpose of inspection, surgery, rehabilitation, etc., the steps for inserting the fork for heaviness are inserted between the two adjacent timbers by alternately raising or lowering the all-folded material. To form.

[0006] In order to maintain the above functions, (A) the bed itself is provided with a unit bed material that is in close contact with each other,
(B) The bed is composed of a main bed and a movable auxiliary bed, and both beds are provided with comb-shaped beds and the auxiliary bed and the auxiliary bed are provided. A type in which when the bed and the bed are united, the bed material of one bed enters between the bed materials of the other bed to form a complete bed surface. It can take two forms.

The former format is the most standard format. The latter type allows the auxiliary bed to be used instead of a stretcher and does not require the transfer work of a stretcher.

Bedclothes In the bed of the present invention, it is a principle that the patient is laid directly on the bedclothes. Therefore, in any of the above-mentioned formats, each unit bedclothes constituting the bed (or the main bed and the auxiliary bed). ,
In particular, it is desirable that the upper surface be made of an appropriate soft material so that the patient does not feel uncomfortable. For example, a hard polyurethane dressing covered with soft polyurethane is an example of a suitable dressing because it has appropriate breathability and is soft against the skin. However, a decubitus material composed of a rubber bag or the like filled with a liquid such as water is suitable because the contact state with the skin is soft and the load is dispersed. In particular, when considering heating, it is technically easy to heat the liquid pressure pudding.

Patients who are users of the bed of the present invention are usually unable to move themselves, so it is necessary to give sufficient consideration to the prevention of pressure sores. Therefore, if necessary, it is desirable to give some depressions and projections to the surface of the bed, and therefore, each bed material may be subjected to a periodic or irregular small elevation movement. In particular, if the lifting motion is automatically performed via a timer, not only the pain of the patient but also the labor of the caregiver can be significantly reduced. However, since the pressure side is a synthetic surface, it is not a strict plane, and there is a slight gap between each unit pressure fold material, and fresh air circulates through the gap to the back of the patient, etc. Breathability is better than conventional mattresses.

The raising and lowering of the bedclothes can be performed individually for each unit bedclothes, and this is necessary especially for the purpose of imparting a wavy uneven movement to the bedclothes, but normally, alternately and It suffices to give the lifting function as a unit. For this reason, in the integrated type, it is preferable that the movable bed member be fixed to the movable frame and the frame be vertically moved by a pressurized fluid pressure (for example, hydraulic pressure) cylinder. Further, in the case of the composite type including the main bed and the auxiliary bed, it is preferable that each bed material of the main bed is fixed to the movable frame and the frame is moved up and down by the pressurized fluid pressure.

Contrary to these, when it is desired to impart a wavy undulating movement to the face of the foot, it is necessary to attach a small lifting mechanism such as a roller type tractor to the column unit that supports each of the face materials.

The method of supporting the decubitus material is determined by the structure of the bed. In the composite bed, it is necessary to have a cantilever structure for the bed material of this bed so as not to obstruct the entrance of the frame material supporting the auxiliary bed. On the other hand, in the integrated bed, there is no particular need to be concerned with the method of supporting the pressure sores.

The above-described lifting and lowering movement of the bedclothes further raises one of the left and right portions (both sides along the longitudinal direction of the bed) and lowers the other absolutely or relatively (that is, the movable bedclothes are moved to the bed). It is desirable to have a function of inclining along a surface along the width direction. This allows the patient to be tilted by the action of the raised movable decubitus, allowing a posture change from a supine position to a recumbent position or vice versa. Since such a posture change has a great effect on the prevention of pressure sores, it is not only to reduce the labor of the caregiver but also to prevent the pain of the patient to configure such exercises every other hour and automatically. Is also useful. In order to carry out this method, for example, the support columns for supporting the pressure sores may be configured to be driven by separate left and right hydraulic mechanisms.

Additional Mechanism, etc. The bed of the present invention can have, as additional equipment, for example, a heating mechanism for a bedclothes, a vibration mechanism for a bedclothes, a hole for defecation, and the like. Although a fork as an auxiliary equipment and its moving means are not the subject of the present invention, in general, a rail leading to a bathroom or the like is attached to the ceiling of a patient room, and a small hoist or pulley is attached from a pulley engaging with the rail. A fork may be attached to the tip of the arm that hangs down via the space between the above-mentioned pressure pleats (see FIG. 2).

[0015]

In the bed according to the present invention, the decubitus material constituting the decubitus surface is movable and allows the fork to enter while the patient is in a supine position.
It is possible to eliminate the trouble of lifting from the bed for the purpose of inspection, rehabilitation, etc., and it is possible for a single woman to easily carry it to a predetermined position. And, since the pressure surface is divided and the air permeability is good, there is little risk of pressure sores, especially by adding wavy motion or partial tilting motion to the pressure surface, the occurrence of pressure sores is eliminated, It is possible to further reduce the pain of the patient and the labor of the caregiver.

[0016]

The present invention will now be described in more detail by way of examples, but the examples are merely for the purpose of illustration and are not meant to limit or limit the inventive idea.

Embodiment 1 FIG. 1 is a cutaway perspective view showing an example in which the present invention is applied to an integrated bed, and FIG. 2 is a perspective view showing an example of a fork lifter.

The bed 1 of this embodiment is a unit which is fixed to the lowermost fixed (base) frame 2, a hydraulic jack 3 mounted on the frame 2, and fixed from above the frame 2 via columns 5 and 5. .., the movable frame 4 fixed on the jack 3, and fixed from the upper surface of the frame 4 via columns 5 ', 5' ... and 5 ", 5". .., movable casters 7, 7 ... Installed below the frame 2, and a pair of guards 8 attached to the front and rear ends of the movable frame 4. The movable unit beds 6b, 6b and 6c, 6c. , 8 and. And each of the beds 6a to 6c are integrated to form a complete bed surface 6. Further, the above hydraulic jack 3
Is a foot-operated hydraulic pump 3a and hydraulic cylinders 3b, 3b.
-, And consists of a foot-operated lever 3c and a foot-operated release lever 3d.

In the state shown in FIG. 1, the movable frame 4 is slightly raised from the lowest position and a step c is formed between the movable frame 4 and the bed surface 6. However, if the frame is further lowered,
The step c is further increased so that each soft material-covered fork 12 of the fork lifter 11 shown in FIG. 2 can enter into the gap (step) between the two adjacent beds. Therefore, when the release lever 3d is stepped on from the state shown in the figure, the frame 4 is gently lowered by its own weight, and the fork 12 is allowed to enter,
Insert the fork 12 into the gap between the patient's back (not shown).

Carry. When the predetermined process is completed, on the contrary, the patient is lowered onto the bed surface 6, the foot lever 3c is operated to raise the movable frame 4, and the bed surface 6 is restored to a substantially flat state to finish the work.

Since the above work is simple and requires little labor, the caregiver's labor is remarkably reduced, and at the same time, the patient is not inflicted with excessive force. And because some clearance between each pressure bolster enhances breathability and circulates fresh air on the patient's back,
Concerns about pressure sores are also significantly reduced.
