Description

{BODY PRESSURE DISPERSION MATTRESS}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pressure-pressure-dispersed mattress, and more particularly, to a pressure-pressure-dispersed mattress that automatically measures and informs the pressure of the pressure-distribution mattress.

In general, when a brain injury or a paraplegic is paralyzed due to various accidents or diseases, the behavior becomes uncomfortable and leads to an unavoidable illness. At this time, when the skin touching the sickbed is subjected to long-term pressure, the blood vessels in the skin are also pressed and the circulation of the blood is not smooth, thereby causing a pressure ulcer, which is a phenomenon of skin rash.

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. These symptoms can be seen in patients who have not been able to freely change their position due to a debilitating patient or cerebrospinal nerve disorder for a long time, and are likely to develop in areas where weight is stressed, especially where bones are exposed. Sometimes it may be stressed by splint or cast. The skin of the stressed part becomes bleak at first because the blood circulation deteriorates, and the circumference becomes red, and tenderness occurs. Later, blisters are formed, and when it goes further, it becomes darker, and the part causing the gangrene (gangrene) is eliminated, and ulcers are formed, which is one of the very dangerous illnesses where odorous secretions come out.

This is due to the unnaturalness of the body and the increased cost for the patient. Such pressure ulcers occur not only in the patients mentioned above but also in those who sit and work for a long time, and it is known that the incidence is high in summer.

To prevent these pressure ulcers, the patient should be wiped clean often. When the skin is red in the beginning, it is necessary to change the position, and it is also necessary to give a donut shaped donkey to the affected area to avoid pressure, and to lightly massage and promote blood circulation. If it is ulcerated, the site is constantly cleansed and an ointment containing a disinfectant is applied.

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, the pressure ulcer is a very dangerous skin injury, so the mattress used by the patient is also used to prevent it.

Various mattresses are now on the market to prevent pressure ulcers. As one of the most widely used types of beds, a cushion (mattress) for preventing bedsore is used as disclosed in Korean Patent Laid-Open No. 10-2008-0075812, in which a plurality of individual air chambers communicating with each other are arranged on a plane .

As shown in FIG. 1, the cushion for preventing pressure ulcer is composed of an upper plate 10 in which protruding structures protruding in one direction for forming a plurality of individual air chambers 40 are arranged in a matrix on a plane, The upper plate 10 and the lower plate 20 are formed of a lower plate 20 in the form of a planar superimposed structure and have a passage portion connecting the air chambers 40 formed by the projecting structure, And the overlapping portions are bonded to each other. 1, reference numeral 60 denotes an air inlet; 30, a liquid silicone rubber material adhesive for bonding the upper plate 10 and the lower plate 20; 11, And a reference numeral 123 denotes a flat portion between the protruding portions 11 of the top plate 10 as an adhesive portion.

In order to prevent the pressure ulcer from occurring by using the cushion for preventing the pressure ulcer, the air pressure inside the cushion for preventing the pressure ulcer must be kept constant while the patient is lying on the pressure ulcer prevention cushion.

However, after the patient was lying down or sitting on the cushion for preventing a pressure ulcer, the pressure of the pressure cushion for preventing the pressure ulcer was checked by a caregiver or the like by inserting the hand into the part where the cushion for preventing the pressure ulcer and the patient's abutment contact each other.

In other words, the caregiver felt the pressure transmitted from the cushion for preventing the pressure ulcer after the hand was put in the part where the cushion for preventing the pressure ulcer and the part for the patient came in contact with each other.

As a result, the pressure transmitted from the pressure ulcer cushion to the affected part of the patient can not be accurately known. Therefore, if the air pressure inside the cushion for preventing the pressure ulcer is not appropriate, the patient's pressure ulcer prevention can not be efficiently performed, but rather, the pressure ulcer can be deteriorated.

In addition, the pressure applied by the cushion for preventing the pressure ulcer must be checked by putting his / her hand into the abutment part between the cushion for preventing the pressure ulcer and the affected part of the patient from time to time. In this case, the caregiver's hands were inevitably in contact with the affected part of the patient.

Especially, in case that the patient 's lesion state is a state in which the ulcer is formed and the odorous secretion comes out, the caregiver can have discomfort when the hand touches the affected part.

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