Description

Technology Field

[0001] The present invention relates to a pressure sore prevention mattress, and more specifically, to a pressure sore prevention mattress characterized by allowing a plurality of cells that support the body to alternately rise and fall, and by allowing air to be discharged between the cells so as to prevent pressure sores, and allowing the length to be variable to fit the body. Background Technology

[0002] Below, the air circulation mat (1) according to the background technology, together with the attached drawings, is as follows.

[0003] FIG. 1 is a perspective view illustrating an air-circulating mat according to the background technology, and FIG. 2 is a cross-sectional view of FIG. 1 taken by cutting a portion of FIG. 1 in the longitudinal direction.

[0004] For the elderly or patients who must remain lying down for long periods due to old age or illness, it is common for bedsores to develop. Since they must stay on a mattress 24 hours a day, sweat generated on the skin in contact with the mattress does not dry, causing the skin to become macerated, and poor blood circulation leads to necrosis. To prevent this, nurses and caregivers frequently assist the elderly or patients in changing their lying positions so they can turn over, but this is an extremely strenuous task.

[0005] To solve this, the prior art literature presented below suggests an air circulation mat (1).

[0006] This comprises a rectangular main body (10) and a plurality of cells (15) protruding from the upper surface of the main body (10). The main body (10) and the cells (15) are formed with an outer shell made of a flexible material, and a space (17) communicating with each other is formed inside the main body (10) and the cells (15). Additionally, an air hole (13) is arranged between the cells (15) on the upper surface of the main body (10). Polyurethane gel (20) that provides a cushioning function is filled into the space (17). Furthermore, an air hose (30) is configured to be introduced laterally from the outside of the main body (10) and penetrate the polyurethane gel (20). The air hose (30) is connected to each other in a rectangular manner inside the main body (10), and an air discharge pipe (40) is configured to be connected to the air hose (30), pass through the polyurethane gel (20) upwardly, and connect to the air hole (13). In addition, an air pump (50) is configured to be placed outside the main body (10) to be connected to the air hose (30).

[0007] According to the air circulation mat (1) described above, when an elderly person or patient lies down, the cell (15) is compressed and provides a cushioning function. Additionally, external air passes laterally through the cell (15), causing sweat generated on the skin to dry. Furthermore, air introduced through the air pump (50) is discharged upward from the main body (10) through the air hose (30) and air discharge pipe (40), thereby drying the sweat and preventing bedsores.

[0008] However, the above air circulation mat (1) had the following problems.

[0009] First, since air is discharged through the air exhaust pipe (40) between the cells (15) and external air is introduced to the sides of the cells (15), bedsores do not occur on the skin that is not in contact with the cells (15). However, since pressure is applied to the skin for a long time in the part of the skin that is in contact with the cells (15), there was a problem that bedsores also occurred on the skin in contact with the cells (15). In particular, the bedsores that occurred in this way spread to the entire area of ​​the skin, and there was a problem that it was not much different from the existing mattress.

[0010] Second, when an elderly person or patient lies on the air-circulating mat (1), the polyurethane gel (20) inside the cell (15) is compressed and presses the air hose (30), causing it to become blocked. As a result, air cannot be discharged smoothly through the air discharge pipe (40), and the sweat generated on the skin cannot be properly dried, which causes the skin to become chafed.

[0011] Third, although it is necessary to manufacture products in various lengths according to human height, the manufacturing process is cumbersome if produced for each size, so they are manufactured uniformly to fit the tallest height. Consequently, there was a problem where people of shorter heights had to bear the additional cost because they purchased products manufactured to fit tall heights. In other words, since products designed for tall heights require more material, the purchase cost is higher than those designed for short heights, which inevitably becomes a burden. Prior art literature

[0012] Korean Utility Model Registration No. 20-0250619 (Registration Date: October 4, 2001) The problem to be solved

[0013] The problem to be solved by the pressure ulcer prevention mattress according to the present invention is as follows.

[0014] First, we aim to solve the problem of pressure sores occurring on the skin in contact with the cell in the background technology, as pressure is applied to the skin for a long time in the part of the skin in contact with the cell.

[0015] Second, when an elderly person or patient lies on the air-circulating mat, the polyurethane gel inside the cell is compressed, which compresses the air hose and causes it to become blocked. Consequently, air cannot be discharged smoothly through the air exhaust pipe, preventing the sweat generated on the skin from being properly dried, which leads to skin irritation.

[0016] Third, we aim to resolve the problem of not being able to manufacture in various lengths depending on human height. means of solving the problem

[0017] The pressure sore prevention mattress according to the present invention is configured as follows to solve the above problem.

[0018] It includes a plurality of support manifolds that support the human body in a bar shape, formed as a rectangular shape extending laterally and having an internal space, and a plurality of exhaust manifolds that are attached to the longitudinal side of the support manifolds, formed as a bar shape extending laterally and having an internal space, and receive air and discharge it upward, and the support manifolds and exhaust manifolds include detachable means attached to mutually opposing sides to allow mutual detachment.

[0019] The support manifold comprises an injection valve connected to one end of the left or right side for injecting air, an exhaust valve connected to the opposite end of the injection valve for exhausting air, an upper hole perforated in the upper surface, and a cell, which is a tube connected to the support manifold to cover the upper hole and protruding upward by the injection of air.

[0020] The exhaust manifold described above includes an air valve connected to one end of the left or right side to allow air to be injected, and an exhaust hole perforated in the upper surface through which the air injected from the air valve is exhausted.

[0021] Additionally, it includes a plurality of branch hoses connected to each of the injection valves, a single main hose connected to each of the branch hoses, and an air pump connected to the main hose, and includes a plurality of branch hoses connected to each of the air valves, a single main hose connected to each of the branch hoses, and an air pump connected to the main hose.

[0022] Additionally, it includes a cushioning sheet that is seated on the upper surface of the support manifold and the exhaust manifold, with a through hole through which the cell passes and an air hole connected to the exhaust hole being perforated.

[0023] In addition, the injection valve and the exhaust valve are solenoid valves, and the apparatus includes a control unit that controls the injection valve and the exhaust valve so that the cell alternately rises and falls. Effects of the invention

[0024] The pressure sore prevention mattress according to the present invention has the following effects through the above-mentioned solution.

[0025] First, since the cell moves up and down periodically, it is possible to prevent pressure sores from developing on the body parts that come into contact with the cell.

[0026] Second, since the body is supported by the cell, air naturally flows in and is discharged from the side of the cell, and since air is blown upward through the exhaust manifold, sweat can be removed quickly. Therefore, it is possible to prevent skin diseases caused by skin chafing or eczema from occurring due to sweat.

[0027] Third, since the length can be adjusted by attaching the support manifold and the exhaust manifold using the above-mentioned detachable means, the size can be easily adjusted according to the height during manufacturing. Brief explanation of the drawing

[0033] Hereinafter, a detailed embodiment of the bedsore prevention mattress (90) according to the present invention will be examined together with the attached drawings as follows.

[0034] FIG. 3 is a perspective view illustrating a pressure ulcer prevention mattress according to the present invention, and FIG. 4 is a perspective view illustrating FIG. 3 with the cushioning cover removed. FIG. 5 is a perspective view illustrating FIG. 3 with the injection hose, air hose, and respective air pump removed, and FIG. 6 is a perspective view illustrating FIG. 5 with the cushioning cover separated. FIG. 7 is a perspective view illustrating a part of the main body of the pressure ulcer prevention mattress according to the present invention, separated into a support manifold and an exhaust manifold, and FIG. 8 is a cross-sectional view taken along the line F-F' of FIG. 4.

[0035] As shown in FIG. 7, a plurality of support manifolds (100) are configured to support the human body in the shape of a bar, which is a metal or synthetic resin material having rigidity, and is formed in a rectangular shape extending to the left and right sides, has a space (107) formed inside, and is formed as a bar.

[0036] In addition, a plurality of exhaust manifolds (200) are configured to be attached to the longitudinal side of the support manifold (100), are formed to be long in the left and right directions, have a space (207) formed inside, and are bar-shaped materials made of a metal or synthetic resin material having rigidity, and receive air and discharge it upward.

[0037] The support manifold (100) and the exhaust manifold (200) are configured with detachable means (180, 260) attached to mutually opposing sides, for example, Velcro tape or rubber magnets. Thus, they are configured to allow for combinations of various lengths depending on the height of the human body.

[0038] The support manifold (100) described above can be examined in conjunction with FIGS. 7 and FIGS. 8 as follows.

[0039] An injection valve (110) is configured to be connected to one end of the left or right side for injecting air, and an exhaust valve (120) is configured to be connected to the opposite end of the injection valve (110) for exhausting air. Additionally, a plurality of upper holes (130) are perforated along the longitudinal direction on the upper surface, and a plurality of cells (140), which are tubes connected to the support manifold (100) to cover the upper holes (130) and protrude upward by the injection of air, are configured. The cells (140) are formed, for example, of rubber material and are configured to support the human body by expanding upward and protruding when filled with air.

[0040] The exhaust manifold (200) described above can be examined in conjunction with FIGS. 7 and FIGS. 8 as follows.

[0041] An air valve (210) is configured to be connected to one end of the left or right side to allow air to be injected, and a plurality of exhaust holes (200) are formed on the upper surface along the length direction to allow the air injected from the air valve (210) to be exhausted.

[0042] Additionally, as shown in FIGS. 3 and 4, a plurality of branch hoses (150) connected to each of the injection valves (110) are configured, a single main hose (160) connected to each of the branch hoses (150) is configured, and an air pump (170) is connected to the main hose (160).

[0043] Additionally, as shown in FIGS. 3 and 4, a plurality of branch hoses (230) connected to each of the air valves (210) are configured, and a single main hose (240) connected to each of the branch hoses (230) is configured, and an air pump (250) is connected to the main hose (240). It is preferable that the air pump (250) be temperature-adjustable so that it can supply cold and hot air. This means that the temperature of the air being sprayed can be adjusted by adjusting the amount of current, like a hair dryer.

[0044] In addition, as shown in FIGS. 3, 5, and 6, a cushioning sheet (300) is formed by perforating a through hole (310) through which the cell (140) passes and an air hole (320) connected to the exhaust hole (220), and is seated on the upper surface of the support manifold (100) and the exhaust manifold (200). For example, it is composed of a cushioning sheet such as styrofoam, urethane foam, non-woven fabric, or woven fabric.

[0045] The injection valve (110) and exhaust valve (120) are solenoid valves, and a control unit (not shown) is configured to control the injection valve (110) and exhaust valve (120) so that the cell (140) is alternately raised and lowered. The control unit is a controllable component, such as a CPU (Central Processing Unit) or a circuit board, and enables a process according to a set program.

[0046] In addition, a pressure sensor (not shown) is configured to be mounted within the support manifold (100) and to transmit pressure data to the control unit (not shown).

[0047] The above control unit (not shown) is configured so that the process is carried out as follows.

[0048] First, when all air is exhausted from the support manifold (100) and the cell (140) is in a contracted and lowered state, each exhaust valve (120) is closed, each injection valve (110) is opened, and the air pump (170) is operated so that air is injected into each support manifold (100) and filled into the cell (140), causing the cell (140) to expand and rise upward. At this time, if the pressure data transmitted from each pressure sensor (not shown) is a set value, the injection valve (110) of the support manifold (100) to which the set pressure data was transmitted is closed, and the air pump (170) corresponding to the injection valve (110) is turned off so that the expanded state of the cell (140) is maintained.

[0049] Next, in one of the support manifolds (100), the exhaust valve (120) is opened and the injection valve (110) corresponding to the exhaust valve (120) is closed so that air inside the support manifold (100) is discharged. At this time, if the pressure data transmitted from the pressure sensor (not shown) is a set value, the exhaust valve (120) is closed and the injection valve (110) is opened, and the air pump (170) is operated to inject air back into the support manifold (100) so that the cell (140) expands and rises upward. At this time, if the pressure data transmitted from the pressure sensor (not shown) is a set value, the injection valve (110) is closed and the air pump (170) is turned off so that the expanded state of the cell (140) is maintained. This process is programmed to operate sequentially for each support manifold (100). For example, the lowering and raising of the cell (140) may be repeated sequentially from the front, or sequentially from the rear, or repeated in an even order such as the second and fourth from the front, and then repeated in an odd order such as the first and third from the front. Of course, the lifting and lowering that operate for each support manifold (100) according to the program can be performed in various sequences.

[0050] The above examples of use of the bedsore prevention mattress (90) according to the present invention are as follows.

[0051] First, the present invention has the advantage of being able to vary the length according to the elongation during manufacturing. That is, by attaching the support manifold (100), exhaust manifold (200), and support manifold (100) in sequence using the detachable means (260), it can be manufactured to a desired length. Therefore, the inconvenience of having to set up production lines for each size during manufacturing can be resolved.

[0052] When using the device manufactured in this way, first, when all air is exhausted from the support manifold (100) and the cell (140) is in a contracted and lowered state, the control unit (not shown) closes each of the exhaust valves (120), opens each of the injection valves (110), and operates the air pump (170) so that air is injected into each of the support manifolds (100) and filled into the cell (140), causing the cell (140) to expand and rise upward. At this time, if the pressure data transmitted from each of the pressure sensors (not shown) is a set value, the injection valve (110) of the support manifold (100) to which the set pressure data was transmitted is closed, and the air pump (170) corresponding to the injection valve (110) is turned off so that the expanded state of the cell (140) is maintained. In this state, when a user lies on the pressure sore prevention mattress (90), multiple cells (140) support the human body. Therefore, there is a gap between the body and the cushioning sheet (300), and air is drawn in laterally and discharged laterally, thereby drying the sweat generated from the body. At the same time, the air pump (250) is operated to inject air into the exhaust manifold (200), and air is sprayed upward through the exhaust hole (220), allowing for more efficient drying of sweat. In particular, since cold air can be sprayed through the air pump (250) in the summer and warm air in the winter, there is an advantage in being able to adjust the air sprayed according to the temperature. Therefore, it is possible to prevent the occurrence of skin diseases such as skin chafing or eczema caused by sweat not being discharged.

[0053] In this state, as shown in FIG. 8, the cells (140) are sequentially raised and lowered for each support manifold (100). Then, because the cells (140) in contact with the body repeatedly touch and fall off periodically, continuous pressure is applied to the skin touching the cells (140), thereby preventing the phenomenon of impaired blood circulation and subsequent ventilation. Additionally, since the cells (140) descend at this time, a part of the body comes into contact with the cushioning sheet (300), thus preventing the phenomenon of ventilation caused by contact with the support manifold (100) or the exhaust manifold (200).
