Description

Bedsore prevention mat

The present invention relates to a pressure ulcer preventive mat capable of dispersing pressure to prevent a pressure ulcer, and more particularly, to a pressure ulcer preventive mat which is improved in firmness by attaching a wick to a leg constituting a mat.

The term "pressure ulcer" refers to a ulcer caused by the death of a tissue due to poor blood circulation due to continuous or repetitive stresses applied to the protrusions of the bones in any part of the body (the tissue surface is locally deficient due to inflammation or necrosis ), The common cause of these symptoms is pressure, more appropriately because it is called compression ulcers.

Pressure ulcers are usually caused by pressure in the same position for extended periods, such as unconscious patients, patients with cranial nerve or spinal cord injuries, patients with severe, elderly, chronic illness, chronic debilitating patients, It does not feel uncomfortable in the receiving area, and it occurs mainly in patients who are uncomfortable but do not have the power to change their position.

The pressure ulcer is caused by the force of compression and tilting. When the pressure ulcer compresses the bone protrusion for a long time, the blood circulation of the soft tissue becomes insufficient, blood clot is formed in the small blood vessel, and the tissue is necrotic. It starts in tissues deep in the vicinity and results in a cone-shaped ulcer with a point on the surface of the skin.

On the other hand, the pressure ulcer caused by the leaning force causes the skin covering the bone to slip on the bone when the force of leaning on the skin occurs. At this time, due to the pulling force between the membrane (fascia) covering the muscle, small blood vessels are folded, pulled or torn When ulcers occur, these ulcers become worse when the bacteria grow and become infected. In order to move the patient in bed, the skin on the sacrum (sac bone) slips even if it is slightly raised to the bed head, resulting in tissue damage due to blood flow disturbance between the shallow fascia of the sacrum and deep fascia.

In order to prevent pressure ulcers, it is very important to remove the pressure. In order to avoid pressure, it is necessary to change the position at least every 2 hours to avoid long-term pressure and to sit vertically on the side of the chair rather than sitting diagonally Thereby reducing tissue damage.

Patients sitting on the chair should change position every hour, and patients who are able to move their weight by themselves should change position every 15 minutes. To remove the pressure, remove pressure such as cushion, air or water mattress It is effective to use the device.

Accordingly, various techniques have been proposed to prevent the pressure ulcer of a patient who is inconvenienced in motion, such as those related to the pressure ulcer prevention cushion.

The upper body 10 is formed by injection molding using rubber to form a plurality of air cells 101 that are upwardly expanded by the pressure of the air at regular intervals in the lateral and vertical directions and another air cell 101 to communicate with the inner space of the air passage 102.

The air cell 101 may be formed in a conical shape or a hemispherical shape when viewed from the front and may have a rectangular, hexagonal, or octagonal cross section. However, the air cell 101 may be formed in a hexagonal shape, And the wrinkled recess 101a are opposed to each other so that the air cells 101 are engaged with each other when viewed in a plan view. When the air cells 101 are completely inflated by the pressure of the air filled in the air cells 101, Effectively suppressing the generation of bedsores by effectively supporting and dispersing the applied pressure.

The upper and lower air cylinders 10 are formed in the shape of a square having a width of about 40 cm and a width of about 40 cm, The edges of the upper portion 10 are formed with the edge portions 103 of 2 to 3 cm to form an air cell 101 for solid connection with the bottom sheet 30 .

The wick 20 is interposed between the upper and lower layers 10 and 30 so that when the upper layer 10 and the bottom layer 30 are adhered together and integrally formed, Thereby increasing the adhesion between the upper and lower layers 10 and 30 to prevent the upper layer 10 and the bottom layer 30 from being separated even under high air pressure.

The core (20) is made of a textile material which is made of a fiber material excellent in durability and flexibility, and is made of polyester or nylon, thereby using a tire cord excellent in durability and excellent in tensile strength, durability and heat resistance .

The bottom paper 30 is formed to have the same size as that of the upper surface of the upper body 10 by using the same rubber as that of the upper body 10 and then the wipes 20 are inserted into the bottom paper 30 to have a durable, 20 are integrally formed with the upper body 10 by being adhered to the lower portion of the upper body 10 together with the upper body 10 and the bottom body 30 so that the wick 20 is interposed therebetween.

That is, the upper surface of the top sheet 10 is joined to the upper surface of the bottom sheet 30 by adhesion so that the upper sheet 10 excluding the air cell 101 and the air passage 102 formed to protrude upward from the upper sheet 10 Are integrally formed with the bottom sheet 30.

The air valve 40 is installed at the inlet of the air inlet 101c protruding from any one of the air cells 101 located at the edge of the plurality of air cells 101 formed in the upper body 10, Or the air injected into the air cell 101 is discharged.

The air valve 40 injects air using a mouth or an air infusion pump. In order to prevent leakage of air injected into the air valve 40, an inlet of the air valve 40 is manually opened and closed It is possible to selectively install any one of the automatic type which is automatically closed by the pressure of the coil spring installed manually or internally and opened by the air pressure when the air is injected from the outside.

The connecting ring 50 is fixed by punching at the corners of the upper and lower pieces 10 and 30 integrally formed of a metal material by bonding so that the string or the like is inserted into the connecting ring 50, It is desirable to install them all at the four corners of @ of the present invention.

Hereinafter, the use of the pressure ulcer-type mat with the technique of the present invention as described above and its operation will be described.

In order to use the pressure ulcer prevention mat of the present invention, the air valve 40 provided at the air inlet 101c formed at one side of the air cell 101 is connected to the air inlet pump by a hose, and then the air inlet 101c, All of the air cylinders 101 formed in the upper body 10 by the air passage 102 connecting the plurality of air cells 101 formed at regular intervals at the upper and lower sides in four directions by injecting tools into the air cells 101 formed with the upper The air cell 101 expands due to the air pressure and swells upward.

When the air cell 101 is pushed upward by hand, the air valve 101 is sealed by sealing the cap of the air valve 40 after completing the air pressure to the air inlet 101c to such an extent that the air cell 101 is not squashed Thereby preventing the air introduced into each of the air cells 101 from leaking through the air valve 40.
