Description

Local body pressure dispersion mechanism

The present invention relates to a local body pressure dispersing mechanism, and more particularly, the pressure to a particular local part of the body is concentrated so that the body pressure by body weight is the lowest local part and gradually increases toward the surroundings. And a local body pressure dispersion mechanism capable of preventing and spraying and supporting pressure.

Paralyzed patients or people with reduced mobility spend most of their time lying on the bed. As such, patients who lie in bed for a long period of time, due to local or excessive pressure, such as back or buttocks, are repeatedly or repeatedly applied, resulting in poor blood circulation and pressure sores.

Bed sores are caused by excessive pressure on the skin due to lying or lying down in the same position for a long time, resulting in tissue damage of the skin and subcutaneous tissue. This compression causes problems with blood circulation to the skin, resulting in necrosis of tissue resulting in tissue damage of the skin and subcutaneous tissue.

Bed sores can occur anywhere in the body, but mainly occurs in the protruding part of the bone, such as sacrum, coccyx, sciatic nodules, trochanters, heel, 65% of the bedsores occur around the pelvis.

Bed sores are most common in unconscious patients, patients with cerebral or spinal nerve damage, critical patients, elderly patients, patients with chronic diseases, chronically debilitated patients, and patients lying in bed.

Such patients do not feel uncomfortable where they are under pressure even if they are in the same position for a long time, and even if they feel uncomfortable, they are likely to be damaged by pressure because they do not have the ability to change their position.

The prevention of pressure sores is very important to remove pressure, it is desirable to avoid the long-term pressure by changing the position every time to avoid the pressure.

In order to prevent bedsores of patients, various products such as bedsore prevention bed, bedsores prevention mat, posture changer tools are disclosed.

First, the

cushion layers

110, 120, and 130 will be described.

The

cushion layers

110, 120, 130 are composed of a plurality.

For example, as shown in FIG. 3, the

cushion layers

110, 120, and 130 include a first cushion layer 110, a second cushion layer 120, and a third cushion layer 130. Can be.

The cushion layer described above may be composed of at least two cushion layers. In addition, the above-described cushion layer may be composed of four or more cushion layers, of course.

Hereinafter, as shown in FIGS. 2 to 4, a case in which the first cushion layer 110, the second cushion layer 120, and the third cushion layer 130 are configured will be described.

Through

holes

110h, 120h, and 130h are formed in the first cushion layer 110, the second cushion layer 120, and the third cushion layer 130, respectively.

As shown in FIGS. 3 and 4, the size of the first through hole 110h formed in the first cushion layer 110 is the smallest.

The size of the second through hole 120h formed in the second cushion layer 120 is larger than that of the first through hole 110h.

The size of the third through hole 130h formed in the third cushion layer 130 is larger than that of the second through hole 120h.

That is, the size of the through hole formed in the upper cushion layer among the upper and lower neighboring cushion layers is smaller than the size of the through hole formed in the lower cushion layer.

When the first cushion layer 110, the second cushion layer 120, and the third cushion layer 130, as shown in the present embodiment, 'the diameter of the first through hole (110h) <the second through hole (120h) ) Is formed so as to satisfy the relationship of diameter < diameter of third through hole 130h '.

Meanwhile, as shown in FIG. 4, the first through hole 110h, the second through hole 120h, and the third through hole 130h are formed to communicate with each other.

Specifically, the second through hole 120h is spaced apart from the edge of the first through hole 110h and is formed at a step with the first through hole 110h.

In addition, the third through hole 130h is spaced apart from the edge of the second through hole 120h and is formed at a step with the second through hole 120h.

That is, the through holes formed in the lower cushion layer are formed at a step with the through holes formed in the upper cushion layer spaced apart from the edges of the through holes formed in the upper cushion layer.

Meanwhile, as shown in FIGS. 5 and 6, the through

holes

110h, 120h, and 130h as described above may be formed in a portion where the bedsore most frequently occurs.

For example, the through

holes

110h, 120h, and 130h may have rectangular shapes corresponding to portions of the first cushion layer 110, the second cushion layer 120, and the third cushion layer 130 corresponding to the hips of the patient. It can be formed as.

For example, the through

holes

110h, 120h, and 130h may correspond to the first cushion layer 110, the second cushion layer 120, and the third cushion layer 130 corresponding to the heel portion of the patient. It may be formed in a bent portion.

Through holes 110h ', 120h', and 130h 'are bent in corresponding portions of the first cushion layer 110, the second cushion layer 120, and the third cushion layer 130 corresponding to the heel portion of the patient. As it is formed to have the advantage that it can be applied to all patients of different body sizes with different height or leg length.

On the other hand, the upper cushion layer is preferably configured to have a greater buffering force than the lower cushion layer.

For example, the uppermost first cushion layer 110 is formed of a softer and more buffered material than the second cushion layer 120 or the third cushion layer 130 is configured to make the patient feel comfortable. desirable.

The first cushion layer 110, the second cushion layer 120, and the third cushion layer 130 described above are preferably formed of a material having good ventilation.

For example, the first cushion layer 110, the second cushion layer 120, and the third cushion layer 130 may be made of a 3D air mesh fabric having breathability.

Specifically, the first cushion layer 110 may be configured by overlapping two 3D air mesh fabric having a thickness of about 7mm.

The second cushion layer 120 may be composed of one piece of 3D air mesh fabric having a thickness of about 15 mm.

In addition, the third cushion layer 130 may be configured by overlapping two sheets of 3D air mesh fabric having a thickness of about 15 mm.

Comparing the 3D air mesh fabric having a thickness of about 7 mm and the 3D air mesh fabric having a thickness of about 15 mm, the thickness of the inner fiber yarn of the 7 mm 3D air mesh fabric is thinner than that of the 15 mm 3D air mesh fabric. It can be seen that formed.

This is inferred that the 15mm 3D air mesh fabric, which is thicker than the 7mm 3D air mesh fabric, has a thickened internal fiber to form a three-dimensional space as the forming thickness becomes thick so that it is not broken during the forming process. You can try

On the other hand, as shown in Figure 3, the first cushion layer 110, the second cushion layer 120, the third cushion layer 130 may be configured to be detachable to each other by the fastening means.

For example,

Velcros

111, 121, and 131 may be provided at at least corner portions of the first cushion layer 110, the second cushion layer 120, and the third cushion layer 130 to form upper and lower cushion layers 110. , 120 and 130 may be coupled to or separated from each other.

According to the cushion layer (110, 120, 130) of the above-described configuration, the body pressure due to the weight is the lowest in the bedsores generated area, so that the body pressure is gradually increased toward the around the bedsores generated area so that the pressure of the bedsores It will help relieve and prevent additional skin damage around the bedsores.

In particular, for example, in a structure such as a concentric tailbone cushion in which all the through holes have the same diameter and are formed to have a cylindrical through hole, the upper edge of the through hole in contact with the body may be reduced, although the pressure of the body to the center of the through hole may be reduced. Because body pressure is concentrated in the part, it causes another problem.

On the contrary, when the size of the through holes formed in the upper cushion layer among the upper and lower neighboring cushion layers, such as the cushion layers 110, 120, 130 of the present embodiment, is smaller than the size of the through holes formed in the lower cushion layer and is configured to communicate with each other. As shown in FIG. 6, as the pressure gradually increases from the pressure sore to the peripheral part of the pressure so that the body pressure is not concentrated in a specific area, the pressure sore can be effectively prevented and the additional skin damage around the pressure sore. You can do it.

Next, the cover layer 200 and the finishing layer 300 will be described.
