Device for preventing bedsores{Apparatus for preventing bedsore}

The present invention relates to a bed sore prevention device that is made in the form of a mattress so that the patient can lie down and that the part in contact with the patient can be changed at any time so that bedsores do not occur.

In general, patients and elderly people who are unable to move on their own spend most of their time lying in bed.

In recent years, as the number of elderly people increases, the number of people living in bed due to diseases such as old age or dementia continues to increase.

However, if you lie in bed for a long time, excessive pressure is continuously and repeatedly applied to areas that come into contact with the bed, such as the back or buttocks, and the capillaries in these areas continue to block, resulting in bedsores that cause the skin tissue to die. do.

These bedsores are a serious disease in which the skin is initially discolored and the upper tissues of the skin begin to become scarred, and the lower tissue, the dermis, is damaged as it progresses, and in severe cases, the subcutaneous fat layer or muscle and bone tissues are also damaged. It occurs frequently in the elderly, and once an outbreak occurs, it is difficult to recover easily.

In order to solve such inconvenience, a bed with an angle adjustment capable of easily changing a patient's posture has been widely used.

However, the angle adjustable bed simply changes the patient's posture by changing the angle of the back, legs, or knees, and the patient's back or buttocks are still in contact with the bed, so the effect of preventing bedsores is insufficient. .
