Description

BACKGROUND OF THE INVENTION Field of the Invention [0001] The present invention relates to a local pressure-

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a local body pressure distributing mechanism, and more particularly, to a local body pressure distributing mechanism, in which pressure on a specific local region of a body is concentrated so that body pressure due to body weight is lowest in a local region, To a local body pressure distributing mechanism capable of supporting pressure and distributing it.

Patients who are paralyzed or inconvenienced most of the time lie on the bed. Patients who lie on the bed for a long period of time may suffer from excessive circulation of locally excessive pressure, such as back or hip, .

A pressure ulcer means that the pressure is applied to the skin due to the laying down or lying down in the same position for a long time, causing damage to the skin and subcutaneous tissues, resulting in a problem of blood circulation to the skin due to pressure and ultimately necrosis of the tissue.

The pressure ulcer can occur in any part of the body, but it occurs mainly in the protruding parts of the bones such as sacrum, osteotomy, sciatic nodule, vagina, heel, etc., and 65% of the pressure ulcers occur around the pelvis.

Pressure ulcers can occur in unconscious patients, patients with cranial nerve or spinal cord injuries, patients with severe, elderly patients, patients with chronic illness, patients with chronic debility, and patients lying in bed.

Such a patient does not feel uncomfortable in a place where pressure is applied even if it is in the same position for a long time, and even if he / she feels uncomfortable, the patient himself / herself is likely to suffer damage due to pressure because there is no power to change his position.

Prevention of pressure ulcers is very important to remove pressure. To avoid pressure, it is desirable to change the position at certain intervals to avoid long-term pressure.

To prevent the patient's pressure ulcer, various products such as a bed for preventing a pressure ulcer, a bed preventing mat, and an attitude changing device are disclosed.

FIG. 1 is a view showing a conventional air mattress for preventing bed dislocation, which is an air mattress for preventing a specific portion from being dented, which is made up of three sheets which are superimposed and sealed with a peripheral portion adhered thereto, A first layer air cell made up of a tubular air cell formed in a lateral direction by a sheet and a second layer air cell made up of a tubular air cell formed in a lateral direction by second and third sheets, The arrangement of the second-layer air cells is formed to be shifted in the longitudinal direction.

However, the conventional air mattress preventing air cushion as described above has an effect of dispersing the body pressure, but does not fundamentally show a solution to the main generated portion of the pressure cushion, so that the body pressure is excessively applied to the occurrence portion of the pressure cushion, There still remains a problem that skin damage may occur.

Hereinafter, the first cushion layer 110, the second cushion layer 120, and the third cushion layer 130 will be exemplarily described as shown in FIGS. 2 to 4.

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.

3 and 4, the first through-hole 110h formed in the first cushion layer 110 is the smallest and the second through-hole 120h formed in the second cushion layer 120 The size of the third through hole 130h formed in the third cushion layer 130 is larger than the size of the second through hole 120h, .

That is, the size of the through hole formed in the upper cushion layer of 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 are formed as in the present embodiment, the diameter of the first through-hole 110h, the diameter of the second through-hole 120h (The diameter of the third through-hole 130h) ".

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

Specifically, the second through-hole 120h is spaced apart from the first through-hole 110h by a step with the first through-hole 110h, and the third through-hole 130h is formed through the second through- 120h, and is formed with a step with the second through-hole 120h.

That is, the through-holes formed in the lower cushion layer are spaced apart from the rim of the through-holes formed in the upper cushion layer, and are formed with a step difference from the through holes formed in the upper cushion layer.

Meanwhile, the through holes 110h, 120h, and 130h as described above may be formed in the portion where the pressure ulcer is most likely to occur, as shown in FIGS. 5 and 6, for example, The through holes 110h, 120h, and 130h may be formed in a rectangular shape in the corresponding portions of the corresponding first cushion layer 110, the second cushion layer 120, and the third cushion layer 130, The through holes 110h ', 120h', and 130h 'may be formed in the corresponding portions of the corresponding first cushion layer 110, the second cushion layer 120, and the third cushion layer 130 in a bent shape.
