Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a tiltable bed, and is particularly suitable for use in assisting a patient in turning over in bed and preventing the occurrence of pressure sores. This invention relates to a tilting bed, and more particularly to a tilting bed that can prevent a patient from falling when the bed is tilted.

[Conventional technology]

Conventionally, methods for tilting the bed include methods in which a mat support member is pivotally supported on the bed frame and swung mechanically, and methods in which an air bag with a triangular cross section is inserted into the underside of the bed. It is being

[Problem that the invention seeks to solve]

By the way, with the conventional means of pivotally supporting the mat support member with respect to the belt frame, the driving device for tilting the mat support member is large-scale, and a safety mechanism such as a stopper is required.
This has the problem of complicating the structure and increasing costs.

In addition, if the air bladder with a triangular cross section is simply inserted under the mat, if the mat is tilted too far, there is a risk that the mat may shift from the air bladder or the patient on the mat may fall off the mat. .

The present invention attempts to solve the above-mentioned problems, and aims to provide a tilting bed that has a simple structure and can safely assist a patient in turning over and rocking.

[Means for solving problems]

In order to achieve the above object, the tilting bed of the present invention includes a substantially rectangular base plate, expandable and deflated air chamber members attached to the left and right sides of the bottom surface of the base plate, and a supply supply for these air chamber members. In the tilting bed equipped with an exhaust means, a push-up mechanism is attached to the left and right edges of the board to push up and bend the left and right edges of the bedding laid on the board, and the push-up mechanism The present invention is characterized in that it is comprised of a push-up member whose one side is pivotally attached to the left and right edges of the substrate, and a lock member capable of holding the push-up member in the push-up state.

[Effect]

In the above-mentioned tilting bed of the present invention, the board is inserted under the bedding such as a mattress or a mattress, and then the left and right edges of the bedding are pushed up by the push-up mechanism attached to the left and right edges of the board. is pushed upward.

Then, the substrate is tilted or swung by supplying air to one of the expandable and deflating air chamber members on the left and right sides of the lower side of the substrate, or by alternately supplying and exhausting both of them, Along with this, the patient also turns over and rocks along with the bedding.

At this time, the left and right edges of the bedding are pushed upward by the push-up mechanism and bent to form a fence, which acts to prevent the patient from falling off the bedding.

〔Example〕

Hereinafter, a tilting bed as an embodiment of the present invention will be explained with reference to the drawings. Figure 1 is an end view thereof, Figure 2 is an end view showing its tilting operation, and Figure 3 is an end view of the bed.
4 is a partial view showing a modification of the pushing up mechanism, and FIG. 5 is a partial diagram showing another modification of the pushing up mechanism.

As shown in FIGS. 1 to 3, a substrate 3 such as an aluminum lattice plate is placed between the underside of a mattress 1 or pinerest 2 as bedding on which a patient A lies and a support surface B such as a tatami surface. is inserted, and bi-foldable air chamber members 4, 4, which can be expanded and contracted, are attached to the left and right sides of the lower surface of the substrate 3, respectively.

As shown in FIG. 3, an electric pump 6 operated by a DC motor 6a is interposed in a supply/exhaust pipe 5 that communicates the left and right air chamber members 4, 4 with each other.

This electric pump 6 can be operated reversibly by rotating the electric motor 6a in the forward and reverse directions, thereby allowing air to be transferred from one of the left and right air chamber members 4, 4 to the other.

That is, one of the three-way switching valves 7, 7 installed in the supply/exhaust pipe 5 is opened to the atmosphere so that air can be taken into the pump 6, and the other is set in the open state of the supply/exhaust pipe 5, so that one side After inflating only the chamber member 4 by supplying air, the three-way switching valves 7, 7 are both shut off from the atmosphere, and the supply/exhaust pipes 5, 5 are opened, and in this way, the left and right air chamber members 4, Air can be moved from one side of 4 to the other by a pump 6. (See Figure 2) Therefore, by rotating the DC motor 6a in the reverse direction at regular intervals using the timer-equipped changeover switch 8 and alternately supplying and exhausting the left and right air chamber members 4, 4, the substrate 3 can be shaken. can be made to perform movements,
This makes it possible to constantly change the body position of patient A and prevent the occurrence of pressure sores.

By the way, in the tilting bed of the present invention, in order to prevent patient A from falling due to the above-mentioned tilting of the base plate 3, as shown in FIG. A push-up mechanism 9 is provided to push up and bend the left and right edges of a mattress 1 and a pine mattress 2 as bedclothes.

This push-up mechanism 9 includes a plate-shaped or frame-shaped push-up member 9b pivotally attached to the left and right edges of the board 3 by hinge pins 9a, and a push-up member 9b that is attached to the left and right edges of the floor covering 1 and the mattress 2. The chain 9c is a locking member capable of maintaining the pushing up state in which the chain 9c' is pushed up and bent.
b is locked near the tip of the end, and the other end 9
c'' can be removably hooked onto a fixing pin 3a on the board 3 via a hook 9d.

By the above-mentioned push-up mechanism 9, the left and right edges of the futon 1 and the mattress 2 are pushed up and bent to form a fence, so that one of the left and right air chamber members 4, 4 is pushed up as shown in FIG. Even if air is supplied to tilt the board 3, the patient A will not fall off the bedding 1, 2.

In addition, the reference numeral 10 in FIGS. 1 and 2 indicates a quilt, and 11 indicates a pillow.

In addition to the push-up mechanism 9 shown in Figs.
As shown in the figure, a wedge-shaped locking member 1 is provided between a push-up member 12b pivotally attached to the left and right edges of the board 3 by hinge pins 12a and the upper surface of the edge of the board 3.
2c may be used.

Further, as shown in FIG. 5, a push-up mechanism may be constituted by a flexible air bag 13 having a substantially triangular cross section when inflated and an air supply/exhaust means for the air bag 13. In this case, the lower surface of the air bag 13 is attached to the upper surface of the edge of the board 3, and the air supplied to the inside of the air bag 13 pushes the edges of the mattress 1 and pine mattress 2 upward as shown in FIG. They begin to form fences.

Note that the wedge-shaped lock member 12 in FIG.
c can also be configured like the air bag 13a in FIG.

〔Effect of the invention〕

As detailed above, the tilting bed of the present invention provides the following effects and advantages.

(1) For patients or elderly people who are sleeping on bedding such as a pine mattress on a support surface such as a tatami surface, place the board and the air chamber members on the left and right sides of the base as one body under the bedding. Just by inserting it, you can change your body position such as turning over or adjusting the tilt. At that time, the push-up mechanism attached to the left and right edges of the board lifts the edges of the bedding laid on the board. Since it can be pushed up to form a fence, it is possible to sufficiently prevent the person lying on the bed from falling to the side.

(2) By alternately supplying and exhausting air to and from the left and right air chamber members under the board, the board can swing smoothly.

(3) Items (1) and (2) above make it possible to efficiently and safely change the position of patients and the elderly, and the structure is simple, which has the advantage of significantly reducing costs compared to conventional swing beds. There is.
