Description

Position change mattress for prevention of bedsores}

The present invention relates to a position change mattress for preventing bedsores that automatically changes the position periodically to prevent the occurrence of bedsores.

In general, bedsores are a condition in which circulation is impaired and subcutaneous tissue is damaged due to continuous pressure being applied to parts of the body when sitting or lying down in one position.

In other words, it is a phenomenon that occurs when air circulation in capillaries is inhibited, which initially causes pain and changes in skin tissue, and if treatment is mild, it can lead to skin necrosis, complications, sepsis, osteomyelitis, and even death.

To solve this problem, air cushions for preventing bedsores with multiple air cells are being released.

The air cushion for preventing bedsores is composed of multiple air cells connected to each other through multiple communication pipes to cushion the user's body weight and facilitate ventilation of parts of the body in contact with the floor. The goal is to create an environment that encourages this.

However, the above-mentioned air cushion for preventing bedsores is not only difficult to manufacture due to its complicated structure, but also requires a large manufacturing cost. Also, replacement and repair occur frequently due to defects in a large number of air cells, so it is not suitable for use by users who require immediate use. The problem is that the inconvenience is very great.

In particular, conventional air cushions for preventing bedsores only reduce the size of body pressure by dispersing it, but the body pressure still acts for a long time, so the effect of preventing bedsores is extremely low.

Figure 1 is a plan view of the position conversion mattress for preventing bedsores according to the present invention, and Figure 2 is a cross-sectional view of the position conversion mattress for preventing bedsores according to the present invention. As shown, the position conversion mattress for preventing bedsores according to the present invention is an air mat ( 100), a diaphragm 200 dividing the interior of the air mat 100, an air inlet pipe 300 connected to the air mat 100, and an air pump 400 connected to the air inlet pipe 300. ), the first valve 500 and the second valve 600 installed on the air inlet pipe 400, and the operation of the air pump 400, the first valve 500, and the second valve 600. It includes a control unit 700 that controls.

The air mat 100 has wrinkles 110 formed along the edges to enable expansion and contraction up and down. And, a diaphragm 200 is provided inside the air mat 100.

The diaphragm 200 divides the interior of the air mat 100 inclined to the left and right. In this way, the interior of the air mat 100 is divided into a left air part 101 and a right air part 102 by the diaphragm 200.

The left air part 101 and the right air part 102 must be securely airtight so as not to communicate with each other.

Meanwhile, the air mat 100 may be made of a synthetic resin material such as PVC, PP, or PE resin, and a buffer portion (not shown) of artificial leather or polyurethane may be formed on the surface.

In addition, the buffer portion may be manufactured using natural bast fibers that have been treated to be antifouling to give a luxurious appearance and prevent it from being easily stained by sweat or contaminants.

In this case, the bast fiber can be selected from flax, jute, and hemp, and after performing a natural dyeing process to obtain the desired color with indigo salt, yellow earth salt, or safflower salt, etc., it is subjected to anti-fouling/stain-repelling processing by impregnating it with chitosan or acetic acid coating solution. It can be manufactured by performing the (Soil Guard, SG) process.

The air inlet pipe 300 is connected to the left air part 101 and the right air part 102, respectively, from the outside of the air mat 100 to allow air to flow into the left air part 101 and the right air part 102. It serves as a passageway for entry and exit.

And, the air pump 400 is connected to the air inlet pipe 300 and supplies air to the left air unit 101 and the right air unit 102.

In this case, the air inlet pipe 300 is composed of a main pipe 310 connected to the air pump 400, and a left branch pipe 320 and a right branch pipe 330 branched from the main pipe 310. You can. The left branch pipe 320 is connected to the left air unit 101 and the right branch pipe 330 is connected to the right air unit 102.

The first valve 500 is installed between the left branch pipe 320 and the right branch pipe 330 to control air supply to the left air unit 101 and the right air unit 102.

The second valve 600 is installed in the left branch pipe 320 and the right branch pipe 330, respectively, to control air discharge.

The control unit 700 controls the operation of the air pump 400, the first valve 500, and the second valve 600.

The control unit 700 is programmed so that the left air unit 101 and the right air unit 102 alternately expand and contract at regular intervals.

Meanwhile, it is preferable that a pressure sensor 800 that detects internal pressure and outputs pressure data to the control unit 700 in real time is installed in the left air unit 101 and the right air unit 102. The pressure sensor 800 is connected to the control unit 700 via wired/wireless.

In this case, the control unit 700 operates the air pump 400, the first valve 500, and the second valve until it reaches a normal value only when the internal pressure input from the pressure sensor 800 is outside a certain range. The operation of the valve 600 is emergency controlled.

In addition, this control unit 700 may be connected to the remote control (R) via wired/wireless.

The remote control (R) is equipped with a button to select three types of position modes: left, horizontal, and right.

The position conversion mattress for preventing bedsores according to the present invention configured as described above operates as follows.

First, when the user turns on the power through the remote control (R), the air pump 400 operates and at the same time the first valve 500 opens in both directions and flows through the left branch pipe 320 and the right branch pipe 330. The same amount of air is supplied to the left air unit 101 and the right air unit 102, respectively.

When air is supplied to both the left air unit 101 and the right air unit 102, the wrinkles 110 of the air mat 100 are straightened and the air mat 100 is expanded flat to a certain height.

The user can relax by lying down or sitting on the flat air mat (100).

Afterwards, when a certain period of time preset by the user elapses or the user changes the position mode using the remote control, the air pump 400, the first valve 500, and the second valve 600 automatically operate and the air mat ( 100) is tilted to the left or right.

That is, when selecting the right mode, as shown in FIG. 3, the first valve 500 opens toward the left branch pipe 320 and closes toward the right branch pipe 330, supplying air to the left air unit 101. At the same time, the second valve 600 installed in the right branch pipe 330 is opened for a certain period of time, and the air from the oil side air portion is discharged.

In this state, the left side of the air mat 100 is inflated higher as the wrinkles 110 are further spread, and on the contrary, the right side of the air mat 100 is contracted as the wrinkles 110 are folded.

As a result, the air mat 100 is inclined overall to the left and upward, and the user's position changes to lie down on the right side.

When a certain period of time passes, the first valve 500 opens on both the left branch pipe 320 side and the right branch pipe 330 side, and the air in the left air part 101 moves to the right air part 102. As a result, the left side of the air mat 100 shrinks as the wrinkles 110 are folded, and conversely, the right side of the air mat 100 shrinks as the wrinkles 110 fold.

In this state, as shown in FIG. 2, the air mat 100 is flattened to a horizontal state and the user's position is changed to lie down flat.

Then, when a certain period of time elapses or the user selects the left mode using the remote control (R), as shown in FIG. 4, the first valve 500 opens toward the right branch pipe 330 and the left branch pipe ( As it closes on the 320 side, air is supplied to the right air part 102, and at the same time, the second valve 600 installed in the left branch pipe 320 is opened for a certain period of time, and the air in the left air part 101 is discharged.

In this state, the right side of the air mat 100 expands higher as the pleated portion 110 is further expanded, and conversely, the left side of the air mat 100 contracts as the pleated portion 110 is folded.

As a result, the air mat 100 is inclined overall to the right, and the user's position changes to lie down on the left side.

In this way, since the user periodically turns to the left and right alternately, the position is automatically switched, so the user's body pressure is not continuously applied to only one side for a long time, thereby preventing the occurrence of bedsores.

Meanwhile, a pressure sensor 800 may be installed in the left air unit 101 and the right air unit 102 to detect internal pressure and output pressure data to the control unit 700 in real time.

In this case, the control unit 700 operates the air pump 400, the first valve 500, and the second valve until it reaches a normal value only when the internal pressure input from the pressure sensor 800 is outside a certain range. The operation of the valve 600 may be set to emergency control.

Therefore, it is possible to prevent an accident in which the air mat 100 bursts when air is excessively supplied to the left air unit 101 and the right air unit 102 at an excessively high pressure.

In addition, as air is excessively discharged from the left air unit 101 and the right air unit 102, the cushioning property decreases, causing pain or promoting the development of bedsores, and the left air unit 101 and the right air unit 102 ) As only one side of the air is discharged excessively, the inclination angle of the air mat (100) increases, preventing an accident in which the user falls away from the air mat (100) while rolling to the left or right.

As such, although the preferred embodiments of the present invention have been described in detail with reference to the drawings, the present invention is not limited to the above-described embodiments, and modifications may be made by those skilled in the art without departing from the spirit of the present invention. It is possible, and such modifications will fall within the scope of the present invention.
