Description

BODY PRESSURE DISPERSION MAT

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a body pressure-releasing mat, and more particularly, to a body pressure-releasing mat for lowering pressure caused by an interfacial pressure on a floor or the like applied to the body.

Bedsore refers to a skin injury caused by contact of the back, waist, shoulder and elbow of a patient lying on the bed with the floor surface.

Pressure ulcers can be seen in patients who have been long-lived in their beds or who can not freely change their positions due to disorders of the cerebrospinal fluid, and they are prone to occur in areas under stress, especially where bones are exposed. In some cases pressure sores may occur due to splints or gibbs.

The skin of the stressed part becomes pale at first because it is bleeding, and it becomes reddened, and tenderness occurs, and later blisters are formed, and when it progresses further, the part causing the gangrene (glandular) disappears and the ulcer And a stinking secretion comes out.

Preventive pressure ulcers are difficult to treat, so prevention of pressure ulcers is important.

To prevent pressure ulcers, you should wipe your body often to keep it clean. It is necessary to change the position of the skin when the skin is initially reddened. Also, it is necessary to apply a donut-shaped scarf to the affected part to prevent the affected part from being pressed, and to massage the skin lightly to promote blood circulation. If you are ulcerated, you should constantly clean the area and apply an ointment with a disinfectant.

In order to prevent pressure ulcers, it is very important to change the patient's position several times a day. In this case, it is recommended that the bedding used is a soft one that does not feed on the pillow, and a quilt or cushion should be used with a lightweight but constant buffer .

For such a patient, pressure ulcers are extremely dangerous. In order to prevent the cushion used by a patient because of a skin injury, it is used.

Currently, various cushions for the prevention of pressure ulcers are sold in the market. Among them, a cushion for preventing bedsore is used in a configuration in which a plurality of individual air chambers communicating with each other are arranged on a plane as disclosed in Korean Patent Laid-Open No. 10-2008-0075812.

As shown in FIG. 1, the cushion for preventing bed dislocation includes an upper plate 10 having protruding structures protruding in one direction for forming a plurality of individual air chambers 40, the upper plate 10 being arranged in a matrix on a plane, The upper plate 10 and the lower plate 20 are formed of a lower plate 20 having a planar shape in which the air chambers 40 are formed by the protruding structure, And the overlapping portions are bonded to each other. 1, reference numeral 60 denotes an air inlet, 30 denotes a liquid silicone rubber material adhesive for adhering the upper plate 10 and the lower plate 20, 11 denotes a portion protruding in one direction (11), and reference numeral 13 denotes a bonding portion which is a flat portion between the protruding portions (11) of the top plate (10).

The interfacial pressure of the bottom surface generated due to the repulsive force of the bottom surface is lower than the interfacial pressure of the lower surface of the lower plate 20 due to the repulsive force of the bottom surface, The user is transmitted to the affected part through the entire surface of the user's body and the user is greatly pressed. This is contradictory to the need to reduce the pressure on the affected part for prevention of the pressure ulcer, thereby preventing the pressure ulcer from being effectively prevented.

A prior art related to the present invention is Korean Patent Laid-Open No. 10-2008-0075812 (published on Aug. 19, 2008).

Referring to these drawings, a body pressure-spreading mat according to an embodiment of the present invention is for preventing a pressure ulcer of a patient by lowering the pressure due to an interfacial pressure of a floor or the like applied to a patient's body, And a lower plate 120.

In the embodiment of the present invention, the upper plate 110 and the lower plate 120 may be made of a thermoplastic polyurethane film.

Thermoplastic Polyurethane is a kind of polyurethane (PU).

Due to the nature of the polyurethane, it is common for the polyurethane to be commercialized after the reaction. In other words, it is hard to use it again like other plastic materials such as vinyl chloride and propylene, and it is burned without melting when heat is applied.

In order to compensate for the disadvantages of such polyurethane and melt it several times and reuse it is thermoplastic polyurethane, which has various advantages as follows.

Thermoplastic polyurethanes are available in various hardness grades and are excellent for impact, friction, cutting and tearing. It is much higher than steel and rubber in friction wear. It has excellent tensile strength and tear strength, and has functions of flexibility and shape memory. Also, it has excellent sound absorption and vibration absorbing power and is sufficient to be applied to various functional products.

By applying the thermoplastic polyurethane which is an excellent material as described above to the upper plate 110 and the lower plate 120, it is possible to provide a body pressure dispersion mat which is excellent not only in various functions, particularly impact, friction, cutting and tearing, Can be provided.

The upper plate 110 includes at least one upper portion formed with a plurality of upper cells 111 protruding upward and having an inner space and a plurality of connecting passages 112 communicating with the upper cells 111 . Air can be supplied to the upper cell 111 through the connection passage 112.

In FIG. 2, only one upper portion 130 is illustrated in the upper plate 110. However, the present invention is not limited thereto. That is, one or more upper portions may be provided on the upper plate. For example, as shown in FIG. 18, four upper portions 310, 320, 330, and 340 may be provided on the upper plate 110.

The projecting height of the upper cell 111 may be formed to be higher than the projecting height of the connecting passage 112. This is because the upper cell 111 forms a large area and substantially supports the load of the patient evenly and bufferably.

On the other hand, the widths of the connection passages 112 connecting the upper cells 111 may be the same, but they may not necessarily be the same. Two to four connecting passages 112 may be formed in one upper cell 112.

The lower plate 120 includes at least one lower portion protruding downward and formed with a plurality of downward cells 121 having an inner space formed therein.

3, only one lower portion 140 is provided in the lower plate 120. In FIG. However, the present invention is not limited thereto. That is, one or more lower portions may be provided on the lower plate. For example, as shown in FIG. 19, four lower portions 510, 520, 530 and 540 may be provided on the lower plate 120.

The lower plate 120 is joined to the upper plate 110 so that at least one upper portion and at least one lower portion are coupled to each other to form at least one coupling portion.

Thus, a plurality of coupling cells each having one coupling space can be formed by being coupled with a plurality of upper cells forming the coupling portion and a plurality of downward cells below the coupling portion.

4, the inner space of the upper cell 111 and the inner space of the lower cell 121 are connected to each other by a coupling cell 170 having one coupling space, ), And then may be disposed through high-frequency bonding or the like.

The downward cell 121 may protrude in the same shape as the upper cell 111, but may not necessarily be. The arrangement of the plurality of downward cells 121 of the lower plate 120 may have the same lattice structure as the arrangement of the plurality of upper cells 111 of the upper plate 110, but this is not necessarily the case.

Therefore, due to the structure in which the conventional anti-sosis prevention cushion shown in Fig. 1 is in contact with the bottom surface of the bottom plate 20 in the planar shape, the interface pressure of the bottom surface, which is generated due to the repulsive force of the bottom surface, The lower surface of the lower plate 120 may be provided with a plurality of (for example, a plurality of By disposing the arrangement structure of the downward cells 121 in a lattice structure, the interface pressure area of the bottom surface is reduced as shown in FIG. 4, so that the phenomenon of pressing of the user's affected part can be alleviated. Accordingly, it is possible to prevent the occurrence of the pressure ulcer of the patient in comparison with the prior art.

Further, the protruding height of the upper cell 111 may be formed to be higher than the protruding height of the lower cell 121, or may be formed to be the same as the protruding height of the lower cell 121.

That is, the protruding height of the downward cell 121 may be lower than the protruding height of the upper cell 111 or may be equal to the protruding height of the upper cell 111, so that the center of gravity of the pressure-

Accordingly, the body pressure-applying dispersion mat according to an embodiment of the present invention has a plurality of downward cells having a lattice structure and a height of the downward cells 121 at the same time Is lower than the height of the upper cell (111).

This makes it possible to relieve the pressure applied to the affected part of the user while stably supporting the affected part of the user when the user touches the body pressure-dispersing mat (for example, when the user sits on the body pressure-dissipating mat).

The upper cell 111 and the lower cell 121 may be formed by expanding a thermoplastic polyurethane (TPU), which is a material of the upper plate 110 and the lower plate 120, in the shape of a metal mold.

At this time, for the uniformity of the thickness, it is necessary to limit the width of the upper cell 111 and the width of the lower cell 121 to about 5 cm or less.

If the thickness is not constant, air pressure is concentrated on the thin part, so that the body pressure dispersion mat may burst, and the prevention of the pressure ulcer can not be stably performed.

In general, cushioning is effective about 6cm when injecting air, and mattress is effective about 8cm when air is injected.

In the case of the thermoplastic polyurethane (TPU) as the material of the cushion for preventing bedsore of the structure shown in Fig. 1, only the upper cell is protruded and its height is limited (about 5 cm) so that the effect of pressure dispersion is low, can not do it.

On the other hand, according to the embodiment of the present invention, when the upper cell 111 and the lower cell 121 protrude simultaneously, 6 cm or 8 cm can be easily applied to a cushion or a mattress, Is efficiently performed.

In addition, each of the plurality of downward cells 121 formed on the lower plate 120 of the body pressure-dispersion mat according to an embodiment of the present invention has a shape of a rectangular parallelepiped having an upper surface opened as shown in FIG. 6 and an inner space formed therein And the lower surface may have a planar structure. The downward cell 121 has a rectangular parallelepiped shape, but is not limited thereto.

Further, each of the plurality of downward cells 121 formed in the lower plate 120 of the body pressure-spreading mat according to an embodiment of the present invention may form the lower cells 121 in different aspects, as shown in FIGS. 7 and 8 A plurality of sub-downward cells 220, 220 formed by a part of the lower plate 120 rising upward from the downward cell 121 and separated by a barrier 210 having a predetermined shape formed in the inner space of the downward cell 121, 222, 224, 226).

In other words, in the case of the downward cell according to another aspect shown in FIGS. 7 and 8, the area contacted with the bottom surface is smaller than that of the downward cell shown in FIG. 6, The interface pressure of the small floor surface is received.

Accordingly, the body pressure dispersion mat having the downward cell structure of FIGS. 7 and 8 further reduces the interfacial pressure of the floor surface given to the user than the body pressure dispersion mat having the downward cell structure of FIG. 6, It may be more effective in preventing bedsore than a dispersed mat.

In FIGS. 7 and 8, it is exemplified that a plurality of subordinate downward cells have four rectangular parallelepiped shapes with open top faces, but the shape and the number are not limited thereto.

As shown in FIGS. 9 and 10, the air injecting portion 116 may be provided at each of the coupling portions and may be formed at a portion other than the coupling portion forming portion of the joining portion of the upper plate 110 and the lower plate 120.

In this case, although not shown in the drawing, the joining portion forming region may be the same as the upper region 130 when viewed from the upper plate 110, or the lower region 140 when viewed from the lower plate 120.

That is, the air injecting portion 116 may be formed in a region other than the upper portion 130 of the joining portion of the upper plate 110 and the lower plate 120. Or the air injecting portion 116 may be formed in a region other than the region of the lower portion 140 among the joining portions of the upper plate and the lower plate 120.

The air injection unit 116 includes an air injection body 113, an air adjustment valve 114, and a sensor housing 115.

The air injection body 113 is formed with air injection holes 113a for introducing air into a plurality of coupling cells 170 forming a coupling portion. One side of the air injection body 113 is inserted into the coupling space of the coupling cell 170 closest to the installation position of the air injection body 113 among the plurality of coupling cells 170.

The air control valve 114 is provided on the other side of the air injection body 113 to adjust the amount of air injected into the air injection hole 113a. At this time, the main body of the air control valve 140 is made of brass material and a separate plastic stopper is installed, so that the air control valve 114 can be installed.

The sensor housing 115 may be installed at one side of the air injection body 113. That is, the sensor housing 115 is inserted into the engagement space of the nearest coupling cell 170. At this time, one side of the sensor housing 115 and one side of the air injection body 113 may be coupled by screwing or may be integrated.

The sensor housing 115 includes an air outlet 115a through which the air through the air injection hole 113a is injected into the coupling space of the closest coupling cell 170 and a plurality of coupling cells 170 And a communication module (not shown) for transmitting the detected vacuum pressure by wire or wireless are mounted.

The structure and configuration of the air injection unit 116 are the same as those of the air injection units 316, 326, 336, and 346 shown in Figs. 18 and 19.

The inner space of the upper cell 111 and the inner space of the downward cell 121 may be filled with all or part of the polyurethane foam or may be filled with the polyurethane foam Can be filled with air, not filled. It may be preferable to fill all or part of the polyurethane foam rather than filling only the air in the coupling space and the connecting passage 112.

The polyurethane foam is a foamed foam using the principle of a mushroom mat. When the air-regulating valve 114 is closed while it is compressed or folded, the air-regulating valve 114 keeps a small volume. .

As a result, the polyurethane foam is filled in the coupling space formed by the inner space of the upper cell 111 and the inner space of the lower cell 121 and the connection passage 112, The downward cell 121, and the connecting passage 112 can be torn or burst, the impact of the user against the floor surface can be alleviated by supporting the user's body.

In addition, due to the self-restoring force of the polyurethane foam, it can be automatically charged even without an air pump, and the ease of use can be greatly improved and the amount of air can be automatically adjusted with proper pressure, thereby providing the most effective buffering function according to the body shape and weight of the patient, It can contribute to prevention.

The body pressure dispersion mat according to an embodiment of the present invention may be disposed in the engagement space formed by the inner space of the upper cell 111 and the inner space of the lower cell 121, And a sensing sensor 150 for sensing an upward pressure of the liquid.

And the detection sensor 150 is provided in the coupling space. However, the present invention is not limited thereto.

The first aspect is a case where the detection sensor 150 is inserted into the polyurethane foam in a state that the polyurethane foam is fully charged in the joint space as shown in FIG. 11, the case where the polyurethane foam is completely filled in each bonding space is exemplified. However, the present invention is not limited thereto, and the sensing sensor 150 may be inserted into the polyurethane foam filled in only a part of the bonding space.

As shown in FIG. 12, in the second cell of FIG. 12, the polyurethane foam is completely filled in the upper cell 111 and the bonding space formed by the lower cells having the plurality of sub- And inserted into the detection sensor 150 on the polyurethane foam. 12 illustrates a case where the polyurethane foam is completely filled in each bonding space. However, the present invention is not limited thereto, and the sensing sensor 150 may be inserted into the polyurethane foam filled in only a part of the bonding space.

The third aspect is that, as shown in FIG. 13, for each bonding space formed by the lower cell 111 and the lower cells having a plurality of sub-down cell structures as shown in FIGS. 7 and 8, the polyurethane foam is completely charged The detection sensor 150 is mounted on the partition 210 separating a plurality of sub-down cells. In this case, the polyurethane foam is fully filled in each joint space in FIG. 13, but the present invention is not limited to this, and the polyurethane foam may be filled only in a part of the joint space.

As shown in FIG. 14, in the fourth embodiment, as shown in FIG. 14, for each coupling space formed by the lower cell 111 and the lower cells having a plurality of sub-down cell structures as shown in FIGS. 7 and 8, The detection sensor 150 is mounted on the partition 210 separating a plurality of sub-cells below the sub-cell.

In the first to third aspects, the polyurethane foam may be formed of a hardened portion of the polyurethane foam that contacts the top of the sensor 150, and a non-hardened portion that is not cured in the remaining region. A diagram illustrating this is shown in Fig. The portion of the polyurethane foam corresponding to the hardened portion is merely an example and is not limited thereto.

The reason why the hardened portion is brought into contact with the upper end of the sensing sensor 150 inserted into the polyurethane foam is that the upper pressure applied to the coupling space is further transmitted to the sensing sensor 150.
