Background technique

The air mattress is a mattress that can be injected with air. It can promote the blood circulation of the human body when placed in the bed, and is widely used in the hospital. Bedridden patients, especially those who are bedridden for a long time and cannot change their position voluntarily, are subject to pressure on local tissues of the body due to long-term bed rest, and blood flow disorders are likely to occur in the compressed local tissues, resulting in tissue ischemia, local inflammatory responses and even external pathogens. Invasion produces local infection, which causes tissue necrosis, resulting in bedsores. As the number one "killer" of bedridden patients, bedsores should be paid enough attention. To prevent bedsores, the most important method is to avoid long-term pressure on local tissues of the body. Turn the patient over every 2-3 hours. This is the most convenient, easiest and most effective way to prevent bedsores. For patients with difficulty in moving and turning over by themselves, skilled nurses or escorts are often required to lead or guide the patient. Assist to roll over.
