Description

Cushion for preventing bedsore that can be alternately lifted}

The present invention is an alternate support bed sore prevention cushion, in more detail, by allowing the air cell unit to alternately support the pressure part of the bed sore through information detected by a temperature sensor or a pressure sensor to prevent bed sore from occurring and The present invention relates to an alternating support bed sore prevention cushion that can significantly reduce the risk of secondary infection at the site of bed sores.

Pressure sores are skin damage caused by ischemia of the skin, subcutaneous fat, and muscles in the area under pressure due to insufficient supply of oxygen and nutrients, and when pressure is continuously applied to a part of the body due to a long immobility. , That means ulcers. These bedsores frequently occur in people with disabilities, such as the elderly, neurological disorders, or patients with severe diseases. Various functional products are being released to prevent bedsores, and among them, cushions for preventing bedsores are most often used in terms of cost.

In this regard, looking at the prior art, for example, in Korean Patent No. 10-1298522, by repeating the process of introducing and discharging air for each independent air cell divided into a plurality of pieces, the pressure by the body's own weight is distributed and It can reduce bedsores, and in particular, detects the highest pressure point through the pressure transmitted to the cushion, recognizes the position of the sacrum, and introduces high-temperature air into the air cell at the highest pressure point to perform a high-temperature air massage. A cushion to prevent pressure sores that can help reduce the pressure caused by blood circulation and prevent skin irritation by removing moisture from the skin is presented.

However, Korean Patent No. 10-1298522 has a limitation in that its effect is inferior in preventing the occurrence of overall bedsores only by detecting the highest pressure point and introducing air. In addition, there is a concern that high-temperature air may be introduced into bedsores that are very vulnerable to high temperatures, resulting in bedsores.

Republic of Korea Patent Publication No. 10-1298522 (2013.08.22.)
