The invention comprises a lower panel having a plurality of plate-shaped air chambers formed by protruding downward, and a plurality of air adjusting members for independently supplying outside air to the plurality of plate-shaped air chambers; and an upper panel combined with the upper portion of the lower panel, having a plurality of upper air chambers arranged in a lattice shape formed by protruding upward. According to the invention, an air cushion structure for preventing bedsores can be provided, in which a user can use the structure in a state adjusted to the user's body characteristics caused by asymmetry of the pelvis and a decrease in muscle mass, by visually selecting air adjusting members corresponding to the positions of the left hip, right hip, left thigh, and right thigh, where the height and force of support are desired to be adjusted, according to the user's body characteristics caused by asymmetry of the hips and thighs.

Description

Technical Field

[0001] This invention relates to an air cushion structure for preventing pressure ulcers, and more specifically, to an air cushion structure for preventing pressure ulcers in which the user, based on their own physical characteristics of asymmetry in the hips and thighs, can intuitively select an air conditioner corresponding to the part of the left hip, right hip, left thigh, and right thigh where the support height and support force are to be adjusted, thereby enabling the user to use the air cushion in a state that is adapted to the physical characteristics caused by pelvic asymmetry and reduced muscle mass. Background Technology

[0002] To prevent bedsores in the elderly, infirm, or disabled, air cushions for preventing bedsores, which are installed in wheelchair seats or beds, are filled with air cushion blocks made of polyurethane foam or the like.

[0003] The aforementioned air cushion block is compressed by expelling air from the surroundings when the user applies a load, and returns to its original shape when the user's load is removed and it draws in surrounding air.

[0004] In this way, when the air cushion is compressed under the weight of the user, the air inside the air chamber is expelled to the surroundings. The support pressure of the air cushion used to prevent bedsores is reduced. As the support pressure in the user's buttocks decreases, the blood flow in the capillaries of the buttocks is not obstructed, thereby preventing bedsores.

[0005] On the other hand, when pelvic asymmetry occurs due to prolonged incorrect posture or when the muscle mass of the buttocks and thighs decreases due to prolonged use of air mattresses used to prevent bedsores, resulting in body asymmetry in the buttocks and thighs of the user, the existing air mattresses used to prevent bedsores have limitations in fully realizing their original functions. Summary of the Invention

[0006] Technical issues

[0007] Therefore, the object of the present invention is to provide an air cushion structure for preventing bedsores, in which the user can intuitively select an air conditioning unit corresponding to the part of the left hip, right hip, left thigh, and right thigh where the support height and support force are to be adjusted, based on the user's own physical characteristics caused by pelvic asymmetry and reduced muscle mass.

[0023] The present invention will now be described in more detail with reference to the accompanying drawings. It should be noted that the same structural elements in the drawings are indicated by the same reference numerals wherever possible. Furthermore, detailed descriptions of well-known functions and structures that might unnecessarily obscure the essence of the invention have been omitted.

[0024] Figure 1 This diagram illustrates the structure of the lower panel 100 constituting the lower part of an air cushion structure for preventing bedsores according to an embodiment of the present invention. Figure 2 for Figure 1 A magnified view of region A in the image.

[0025] Figure 3 This diagram illustrates the structure of the upper panel 300 constituting the upper part of an air cushion structure for preventing bedsores according to an embodiment of the present invention. Figure 4 for Figure 3 A magnified view of region B in the image.

[0026] Reference Figure 1 and Figure 3 An embodiment of the present invention provides an air cushion structure for preventing bedsores, comprising: a lower panel 100, the lower surface of which is disposed in contact with a wheelchair or the like; and an upper panel 300, which is coupled to the upper part of the lower panel 100.

[0027] like Figure 1 As shown, the lower panel 100 protrudes downward to form four rectangular plate-shaped air chambers 110. External air is independently supplied to the four rectangular plate-shaped air chambers 110 through four air conditioning components 200, as follows: Figure 3 As shown, the upper panel 300 is provided with a grid pattern of multiple upper air chambers 310 protruding upwards.

[0028] like Figure 1As shown, the four plate-shaped air chambers 110 consist of a first plate-shaped air chamber 110-1 supporting the user's left thigh, a second plate-shaped air chamber 110-2 supporting the user's right thigh, a third plate-shaped air chamber 110-3 supporting the user's left hip, and a fourth plate-shaped air chamber 110-4 supporting the user's right hip. The four plate-shaped air chambers 110 support the user's left and right hips and left and right thighs with independent support height and support force, respectively.

[0029] Specifically, the user can adjust the amount of air filling the first plate-shaped air chamber 110-1 through the first air conditioning component 200-1, and adjust the support thickness and elastic support force of the first plate-shaped air chamber 110-1 according to the muscle mass and height of their left thigh.

[0030] Meanwhile, the user can adjust the amount of air filling the second plate-shaped air chamber 110-2 through the second air conditioning component 200-2, and adjust the support thickness and elastic support force of the second plate-shaped air chamber 110-2 according to the muscle mass and height of their right thigh.

[0031] Furthermore, the user can adjust the amount of air filling the third plate-shaped air chamber 110-3 through the third air conditioning component 200-3, and adjust the support thickness and elastic support force of the third plate-shaped air chamber 110-3 according to the muscle mass and height of their left buttock.

[0032] Meanwhile, the user can adjust the amount of air filling the fourth plate-shaped air chamber 110-4 through the fourth air conditioning component 200-4, and adjust the support thickness and elastic support force of the fourth plate-shaped air chamber 110-4 according to the muscle mass and height of their right buttock.

[0033] On the other hand, such as Figure 3 As shown, the plurality of upper air chambers 310 are composed of an upper air chamber 310 in a first region 1 of the upper air chamber 310 located in the upper region 1 of the first plate-shaped air chamber 110-1, an upper air chamber 310 in a second region 2 of the upper air chamber 310 located in the upper region 2 of the second plate-shaped air chamber 110-2, an upper air chamber 310 in a third region 3 of the upper air chamber 310 located in the upper region 3 of the third plate-shaped air chamber 110-3, and an air chamber 310 in a fourth region 4 of the upper air chamber 310 located in the upper region 4 of the fourth plate-shaped air chamber 110-4.

[0034] Specifically, as the upper part of the lower panel 100 is combined with the upper panel 300, the internal space of the first plate-shaped air chamber 110-1 located at the corresponding position is integrated with the internal space of the upper air chamber 310 of the first region 1, thereby forming an internal space with a grid pattern forming hemispherical protrusions on a rectangular panel of a specified thickness.

[0035] Simultaneously, the internal space of the second plate-shaped air chamber 110-2 located at the corresponding position is integrated with the internal space of the upper air chamber 310 of the second region 2, the internal space of the third plate-shaped air chamber 110-3 located at the corresponding position is integrated with the internal space of the upper air chamber 310 of the third region 3, and the internal space of the fourth plate-shaped air chamber 110-4 located at the corresponding position is integrated with the internal space of the upper air chamber 310 of the fourth region 4, thereby forming internal spaces in the form of hemispherical protrusions in a grid pattern on a rectangular panel of a specified thickness.

[0036] In the internal spaces that are formed independently for each of the first region 1 to the fourth region 4, elastic materials such as polyurethane foam of the same shape (forming hemispherical protrusions in a grid pattern on a rectangular panel of a specified thickness) are filled.

[0037] On the other hand, when the elastic material is restored to its elasticity after being subjected to pressure by the weight of a person, the external air supplied through each of the open air conditioning units 200 fills the relevant internal space.

[0038] Meanwhile, users can individually adjust the air filling level in the internal spaces formed independently of the first zone 1 to the fourth zone 4 by operating multiple air conditioning components 200, thereby individually adjusting the support height and elastic support force of the cushion structure for preventing bedsores in the first zone 1 to the fourth zone 4.

[0039] On the other hand, such as Figure 1 As shown, the lower panel 100 has a downwardly protruding lower air delivery channel 130 that independently connects each air conditioning component 200 and each plate-shaped air chamber 110.

[0040] Specifically, the lower air delivery channel 130 is interconnected with the first air conditioning component 200-1 and the first plate-shaped air chamber 110-1, interconnected with the second air conditioning component 200-2 and the second plate-shaped air chamber 110-2, interconnected with the third air conditioning component 200-3 and the third plate-shaped air chamber 110-3, and interconnected with the fourth air conditioning component 200-4 and the fourth plate-shaped air chamber 110-4.

[0041] On the other hand, such as Figure 3 As shown, at the same position as the lower air delivery channel 130 described above, the upper air delivery channel 330 protrudes upwards from the upper panel 300.

[0042] That is, such as Figure 3 As shown, an upper air delivery channel 330 protrudes upward from the upper panel 300 and is formed therein, which independently connects each air conditioning component 200 to the upper air chamber 310 of each region 1, region 2, region 3, and region 4.

[0043] The aforementioned upper air delivery channels 330 are interconnected with the first air conditioning component 200-1 and the upper air chamber of the first region 1, interconnected with the second air conditioning component 200-2 and the upper air chamber 310 of the second region 2, interconnected with the third air conditioning component 200-3 and the upper air chamber 310 of the third region 3, and interconnected with the fourth air conditioning component 200-4 and the upper air chamber 310 of the fourth region 4.

[0044] The upper air delivery channel 330 is formed at the same position as the lower air delivery channel 130. Thus, with the lower panel 100 and the upper panel 300 combined, the lower air delivery channel 130 and the upper air delivery channel 330 overlap each other to form a cylindrical air delivery channel.

[0045] On the other hand, the upper air delivery channel 330 is formed in a symmetrical shape at the same position as the lower air delivery channel 130, and it is also formed at a position where the lower air delivery channel 130 is not formed.

[0046] Specifically, such as Figure 3 As shown, the upper panel 300 also protrudes to form upper air transport channels 330 for adjacent upper air chambers 310 in the first region 1, upper air transport channels 330 for adjacent upper air chambers 310 in the second region 2, upper air transport channels 330 for adjacent upper air chambers 310 in the third region 3, and upper air transport channels 330 for adjacent upper air chambers 310 in the fourth region 4.

[0047] In this way, the upper air delivery channel 330 of the upper air chambers 310 located in adjacent positions in each of the regions 1, 2, 3 and 4 serves as a connecting channel with a semi-cylindrical shape, which allows the air supplied by each air conditioning component 200 to diffuse to the entire upper air chamber 310 in the relevant regions 1, 2, 3 and 4.

[0048] The connecting channels of the aforementioned interconnected upper air chambers 310 are spread out along the upper surface of the elastic material in the form of a grid-shaped hemispherical protrusion on a rectangular panel of a specified thickness filled in the internal space formed independently relative to the first region 1 to the fourth region 4. Air moving along the connecting channels moves through the flat upper surface of the panel in the elastic material and is delivered to the adjacent upper air chambers 310.

[0049] On the other hand, such as Figure 2As shown, in the present invention, among the plurality of air conditioning members 200 disposed at the center of one side surface of the air cushion structure for preventing bedsores, the first air conditioning member 200-1 and the second air conditioning member 200-2 disposed at the center are respectively connected to the first plate-shaped air chamber 110-1 and the second plate-shaped air chamber 110-2 located adjacent to the plurality of air conditioning members 200 through the lower air delivery passage 130. The lower air delivery passage 130 connects the corner regions closest to the plurality of air conditioning members 200 in the first plate-shaped air chamber 110-1 and the second plate-shaped air chamber 110-2, so that the air delivery paths from the lower air delivery passage 130 to the first plate-shaped air chamber 110-1 and the second plate-shaped air chamber 110-2 can be set to the shortest distance, thereby realizing rapid external air supply and discharge in the first plate-shaped air chamber 110-1 and the second plate-shaped air chamber 110-2.

[0050] Meanwhile, as shown in Figure 2 , the lower air delivery passage 130 is respectively connected to the first plate-shaped air chamber 110-1 and the second plate-shaped air chamber 110-2 through a bifurcated structure, so that more rapid external air supply and discharge in the first plate-shaped air chamber 110-1 and the second plate-shaped air chamber 110-2 can be realized.

[0051] On the other hand, as shown in Figure 1 , among the plurality of air conditioning members 200 disposed at the center of one side surface of the air cushion structure for preventing bedsores, the third air conditioning member 200-3 and the fourth air conditioning member 200-4 disposed on the left and right sides are connected to the third plate-shaped air chamber 110-3 and the fourth plate-shaped air chamber 110-4 located at positions spaced apart from the plurality of air conditioning members 200 through the lower air delivery passage 130, and are connected through the lower air delivery passage 130 formed in a "U" shape along the edge of the lower panel 100, so that external air can be supplied to the third plate-shaped air chamber 110-3 and the fourth plate-shaped air chamber 110-4 without being interfered by the first plate-shaped air chamber 110-1 and the second plate-shaped air chamber 110-2.

[0052] Meanwhile, in the process of implementing the present invention, in the "U"-shaped lower air delivery passage 130 connecting the fourth air conditioning member 200-4 and the fourth plate-shaped air chamber 110-4, in the "L"-shaped region formed around the fourth plate-shaped air chamber 110-4, a plurality of branched structures formed by branching may be provided to simultaneously supply external air to the fourth plate-shaped air chamber 110-4 from a plurality of different positions.

[0053] Through the branch structure of the lower air supply channel 130, the length of the lower air supply channel 130 that supplies air to the fourth plate-shaped air chamber 110-4 is longer than the length of the lower air supply channel 130 that supplies air to the second plate-shaped air chamber 110-2. Nevertheless, it is still possible to make the supply and discharge speed of air in the fourth plate-shaped air chamber 110-4 consistent with the supply and discharge speed of air in the second plate-shaped air chamber 110-2.

[0054] Furthermore, in the implementation of the present invention, in the lower air supply channel 130 of the "U"-shaped structure connecting the third air conditioning member 200-3 and the third plate-shaped air chamber 110-3, in the left-right reversing "L"-shaped area formed around the fourth plate-shaped air chamber 110-3, in order to supply external air to the third plate-shaped air chamber 110-3 from multiple different positions simultaneously, multiple branch structures can be provided.

[0055] Through the branch structure of the lower air delivery channel 130, the length of the lower air delivery channel 130 that supplies air to the third plate-shaped air chamber 110-3 is longer than the length of the lower air delivery channel 130 that supplies air to the first plate-shaped air chamber 110-1. Nevertheless, it is still possible to make the supply and discharge speed of air in the third plate-shaped air chamber 110-3 consistent with the supply and discharge speed of air in the first plate-shaped air chamber 110-1.

[0056] And, as Figure 3 and Figure 4 As shown, in this invention, among the multiple air conditioning components 200 disposed in the center of one side of the air cushion structure for preventing bedsores, the first air conditioning component 200-1 and the second air conditioning component 200-2 disposed in the center are respectively connected to the upper air chamber 310 of the first region 1 and the upper air chamber 310 of the second region 2 located adjacent to the multiple air conditioning components 200 through the upper air delivery channel 330. In the rectangular first region 1 and the rectangular second region 2, the upper air delivery channel 330 connects the corner regions most adjacent to the multiple air conditioning components 200, so that the air delivery channel delivered to the upper air chamber 310 of the first region 1 and the upper air chamber 310 of the second region 2 through the upper air delivery channel 330 forms the shortest distance, thereby realizing the rapid supply and discharge of external air to the upper air chamber 310 of the first region 1 and the upper air chamber 310 of the second region 2.

[0057] At the same time, such as Figure 4 As shown, the upper air delivery channel 330 is connected to the first region 1 and the second region 2 respectively through a two-pronged branch structure, which can also realize a faster supply and discharge of external air to the upper air chamber 310 of the first region 1 and the upper air chamber 310 of the second region 2.

[0058] On the other hand, as shown in Figure 3 , among the plurality of air adjustment members 200 disposed at the center of one side surface of the air cushion structure for preventing bedsores, the third air adjustment member 200-3 and the fourth air adjustment member 200-4 disposed on the left and right sides are connected to the third region 3 and the fourth region 4 which are spaced apart from the plurality of air adjustment members 200 by the upper air delivery passage 330. The upper air delivery passage 330 is formed in a "U" shape along the edge of the upper panel 300, so that external air can be supplied to the upper air chamber 310 of the third region 3 and the upper air chamber 310 of the fourth region 4 without being interfered by the upper air chamber 310 of the first region 1 and the upper air chamber 310 of the second region 2.

[0059] Meanwhile, in the process of implementing the present invention, in the left-right reversed "U"-shaped upper air delivery passage 330 connecting the fourth air adjustment member 200-4 and the upper air chamber 310 of the fourth region 4, in the left-right reversed "L"-shaped region formed along the periphery of the fourth region 4, a plurality of branched structures formed by branching may be provided to simultaneously supply external air to the upper air chamber 310 of the fourth region 4 from a plurality of different positions.

[0060] Through the branched structure of the upper air delivery passage 330 described above, the length of the upper air delivery passage 330 that supplies air to the fourth region 4 is longer than the length of the upper air delivery passage 330 that supplies air to the second region 2. Nevertheless, the air supply and discharge speed in the upper air chamber 310 of the fourth region 4 can be made consistent with the air supply and discharge speed in the upper air chamber 310 of the second region 2.

[0061] Moreover, in the process of implementing the present invention, in the "U"-shaped upper air delivery passage 330 connecting the third air adjustment member 200-3 and the upper air chamber 310 of the third region 3, in the "L"-shaped region formed along the periphery of the third region 3, a branched structure formed by branching may be provided to simultaneously supply external air to the upper air chamber 310 of the third region 3 from a plurality of different positions.

[0062] Through the branched structure of the upper air delivery passage 330 described above, the length of the upper air delivery passage 330 that supplies air to the upper air chamber 310 of the third region 3 is longer than the length of the upper air delivery passage 330 that supplies air to the upper air chamber 310 of the first region 1. Nevertheless, the air supply and discharge speed in the upper air chamber 310 of the third region 3 can be made consistent with the air supply and discharge speed in the upper air chamber 310 of the first region 1.

[0063] On the other hand, as shown in Figure 1As shown, during the implementation of the present invention, the lower surface of each plate-shaped air chamber 110 is partially pressed and has a pressing part 150 that forms a joint with the lower surface of the upper panel 300. When too much external air is supplied by the air conditioning member 200, the bottom surface of the plate-shaped air chamber 110 bulges up, thereby preventing the user's comfort from decreasing when sitting down.

[0064] Thus, with this invention, when a user sits down, they can select at least one of the four air conditioning units 200 located under their crotch to operate, thereby intuitively and individually adjusting the support height and elastic support force of the left buttock, right buttock, left thigh, and right thigh in the cushion structure for preventing bedsores.

[0065] On the other hand, during the implementation of this invention, production personnel can also... Figure 3 The upper panel 300, which is shown in the shape pressing process, and the upper panel 300 with the shape pressing process. Figure 1 The four internal spaces formed between the lower panel 100, which are processed into the shape shown, are each filled with an elastic material of the aforementioned shape. With multiple air conditioning components 200 respectively installed, the upper panel 300 and the lower panel 100 are heat-pressed together by pressing. This process is carried out simultaneously with or after the heat-pressing of the upper panel 300 and the lower panel 100, and is then formed by pressing. Figure 1 The air cushion structure for preventing bedsores of the present invention is manufactured by pressing part 150.

Unless the context clearly indicates otherwise, singular expressions include plural expressions. In this application, terms such as "comprising" or "having" should be understood as specifying the presence of features, numbers, steps, operations, structural elements, components, or combinations thereof described in the specification, without precluding the possibility of the presence or addition of one or more other features, numbers, steps, operations, structural elements, components, or combinations thereof.

[0067] The preferred embodiments and application examples of the present invention have been illustrated and described above. However, the present invention is not limited to the specific embodiments and application examples described above.
