Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bed for preventing acne, so-called bed sore.

[0002]

2. Description of the Related Art Since most of the conventional lying surfaces of beds are fixed type, there are various cases such as bedridden old people, sick people who need time to recover after surgery, and sick people who have weak muscles and cannot turn over by themselves. For people, not only sleepiness but also insomnia, bed sores, etc. are painless.

In addition, it may be difficult for the nurses in the surroundings to assist in changing the posture of the sick person, such as turning over every 1-2 hours at night, depending on the medical condition.

For this reason, beds for preventing acne of this kind have been conventionally developed, and there are beds in which the lying surface is made to roll, and beds in which the lying surface is constituted by an air mat.

The rolling bed drive system is mechanical, that is, a motor is used, or a hydraulic cylinder or an air cylinder is used.

[0006]

However, since the above-mentioned conventional rolling type bed is mechanically driven, not only is the manufacturing cost high, but in some cases noise and vibration are large, which disturbs sleep. Had challenges.

Further, in the above conventional air mat type bed, a concentrated load is applied to a specific portion that supports the body,
There was a problem that the part was always compressed, poor blood circulation was not improved, and it was not very useful for preventing bed sores.

Therefore, the present invention has been made in order to solve the problems of the conventional beds for preventing pimples, and it is a bed for preventing pimples in which noise and vibration are small and poor blood circulation is completely eliminated. It is made for the purpose of providing.

[0009]

Therefore, in the bed for preventing acne according to the present invention, a fixed base 2 having a plurality of convex portions 6 formed in the width direction and a movable base 4 having a plurality of openings 7 formed in the width direction are provided. And the movable table 4 is movable up and down and swingable in the width direction by the airbag 3 of the airbag type drive device, and the convex portion 6 of the fixed table 2 can be retracted from the opening 7 of the movable table 4. .

The bed for preventing acne according to the present invention comprises:
The four corners of the fixed base 2 are supported by the legs 1, and the airbags 3 of the airbag drive device are installed on the upper portions of the legs 1, respectively.
Therefore, the four corners of the movable table 4 can be supported.

[0011]

In the bed for preventing acne according to the present invention, since the movable table 4 can be vertically moved and swung in the width direction by the airbag 3 of the airbag type drive device, the structure can be simplified. , The manufacturing cost is reduced, and the noise and vibration are reduced.

Further, the bed for preventing acne according to the present invention comprises:
Since it is possible to completely replace the part that supports the body,
Poor blood circulation can be completely eliminated.

[0013]

Embodiments of the bed for preventing acne according to the present invention will be described below in detail with reference to the drawings shown as embodiments.

FIG. 1 is an overall perspective view of a bed for preventing acne according to the present invention, in which four legs 1 support four corners of a fixing base 2 and the upper portions of these legs 1 are supported. An air bag 3 of an air bag type drive device is installed, and the four corners of a moving table 4 are supported by these air bags 3.

Although not shown, the air bag type drive device is provided with a pressurized air supply valve and a switching valve in addition to the air bag 3, and a switching valve is provided in the air bag 3 via a hose 5. By the operation, the pressurized air is supplied from the pressurized air supply source and the air in the airbag 3 is discharged. The supply of the pressurized air and the exhaust of the air inside the airbag 3 are controlled by a timer or a switch.

The fixed base 2 has a plurality of convex portions 6 formed in the width direction, and the movable base 4 has a plurality of openings 7 formed in the width direction. The movable table 4 is vertically movable and swingable in the width direction by the airbag 3 of the airbag drive device, and the convex portion 6 of the fixed table 2 is freely retractable from the opening 7 of the movable table 4.

The operating state of the bed for preventing acne according to the present invention having the above-described structure will be described below.

First, as shown in FIG. 1, in a state where the convex portion 6 of the fixed base 2 is projected from the opening 7 of the movable base 4, after a certain period of time, the switching valve is activated by a timer or a switch operation. Pressurized air is supplied from the compressed air supply source to the airbag 3 on one side of the bed, and one side of the moving table 4 moves upward. Then, as shown in FIG. 2, when one side of the movable table 4 moves above the fixed table 2 to a certain position, the switching valve closes.

In the state shown in FIG. 2, after a lapse of a certain period of time, a switching valve is operated by a timer or a switch operation, air in the airbag 3 is discharged, and one side of the moving table 4 that has moved upward is shown in FIG. Return to the original state shown in.

In the state shown in FIG. 1, after a lapse of a certain period of time, a switching valve is actuated by a timer or a switch operation so that pressurized air is supplied from the pressurized air supply source to the airbag 3 on the other side of the bed, and the movable table is moved. The other side of 4 moves upward.
Then, when the other side of the movable table 4 moves above the fixed table 2 to a certain position, the switching valve closes.

After a lapse of a certain period of time, a switching valve is operated by a timer or a switch operation to discharge the air in the airbag 3, and the other side of the moving base 4 which has moved upward is in the original state shown in FIG. Return to.

Thereafter, by repeating the same operation,
Since the movable table 4 swings in the width direction of the bed, the position where the sleeping person's body is supported is constantly changed, so that blood circulation at a certain part of the sleeping person's body does not deteriorate. In addition, since the effect of turning over by changing the body position is exerted, a good sleep can be obtained.

In the bed for preventing acne according to the present invention,
By supplying pressurized air from the pressurized air supply source to the airbags 3 on both sides of the bed, both sides of the moving table 4 are simultaneously moved upward as shown in FIG. 3, and both sides of the moving table 4 are fixed. The switching valve may be closed when it moves to a certain position above the table 2. By doing so, the body supporting portion is completely replaced from the fixed base 2 to the movable base 4, so that the sleeping person can eliminate the poor blood circulation of the body without turning over.

[0024]

The bed for preventing acne according to the present invention is configured as described above and has a simple structure.
Manufacturing costs are lower, and noise and vibration are lessened by the air bag drive, so sleep is no longer disturbed.

In the bed for preventing acne according to the present invention,
Since it is possible to completely replace the part that supports the body,
It is possible to completely eliminate poor circulation, which is very effective in preventing bedsores.
